專利文獻1：日本國特開平7-62924號公報 Patent Document 1: Japanese Patent Laid-Open No. 7-62924

上述先前技術中，為了支撐被安裝於藉由舉升裝置而被舉升之內側槽板的下側之下一個內側槽板，係設置附腳架台(參考專利文獻1的第8圖)。然後在將最下段的內側槽板安裝於內槽屋頂後，撤除附腳架台，並將珍珠岩混凝土塊及環形平板組裝於內槽應被放下之環形區域(參考專利文獻1的第11圖)。亦即，上述先前技術中，由於將附腳架台設置在外槽的底部，而使將保冷材鋪設於外槽的底部之保冷作業成為作業瓶頸，而無法充分地縮短圓筒型槽的工期。 In the above prior art, in order to support the lower inner side groove plate which is attached to the lower side of the inner groove plate which is lifted by the lifting device, a foot stand is provided (refer to Fig. 8 of Patent Document 1). Then, after attaching the lowermost inner groove plate to the inner groove roof, the foot stand is removed, and the perlite concrete block and the annular flat plate are assembled in the annular region where the inner groove should be lowered (refer to FIG. 11 of Patent Document 1). . That is, in the above prior art, since the foot stand is placed at the bottom of the outer tub, the cold-preserving operation of laying the cold-preserving material on the bottom of the outer tub becomes a work bottleneck, and the period of the cylindrical groove cannot be sufficiently shortened.

本發明係鑒於上述問題點而創作者，其目的在於提供一種能夠消除內槽的組裝作業與外槽底部的保冷作業之干涉而縮短工期之圓筒型槽的構築方法。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a method for constructing a cylindrical groove which can eliminate the interference between the assembly work of the inner tank and the cold storage operation at the bottom of the outer tank to shorten the construction period.

為了解決上述課題，本發明之第一型態是一種圓筒型槽的構築方法，其係具有下述步驟：在混凝土製外槽的內側，交互地重複進行由舉升裝置所進行之內槽側板的上升、以及下一個內槽側板對前述上升後之內槽側板的下側之安裝，以組裝金屬製的內槽之步驟；該圓筒型槽的構築方法係具有：以橫跨位在前述外槽的底部且為前述所組裝之內槽應被放下之環形區域之方式，設置用以支撐前述內槽側板之附腳架台之步驟；在前述附腳架台的下方，將用以支撐前述所組裝之內槽之環形部形成於前述環形區域之步驟；以及在前述環形部的形成後，將配置在較前述 環形部更靠近槽內側之前述附腳架台的腳部，插換至前述環形部之上之步驟。 In order to solve the above problems, a first aspect of the present invention is a method of constructing a cylindrical groove, which has the following steps: alternately repeating an inner groove by a lifting device on the inner side of a concrete outer groove The step of assembling the metal inner groove by the rise of the side plate and the mounting of the next inner groove side plate to the lower side of the raised inner groove side plate; the cylindrical groove is constructed by: a step of supporting the abutment frame of the inner groove side plate in a bottom portion of the outer groove and a ring-shaped region in which the inner groove to be assembled is to be laid down; below the aforementioned foot stand, for supporting the foregoing a step of forming an annular portion of the inner groove formed in the annular region; and after the formation of the annular portion, is disposed in the foregoing The step of the annular portion closer to the foot of the aforementioned footrest table on the inner side of the groove is inserted into the annular portion.

本發明之第一型態中，係在形成於用以支撐內槽側板之附腳架台的下方之空間中，於外槽的底部形成環形部。然後在環形部的形成後，將配置在較環形部更靠近槽內側之附腳架台的腳部插換至環形部之上，藉此可消除在槽內側的外槽底部之與保冷作業的干涉。因此，本發明中，可避免內槽的組裝作業與外槽底部的保冷作業之干涉。 In the first aspect of the present invention, an annular portion is formed in a bottom portion of the outer groove in a space formed below the foot stand for supporting the inner groove side plate. Then, after the formation of the annular portion, the leg portion of the abutment frame disposed closer to the inner side of the groove than the annular portion is inserted over the annular portion, thereby eliminating interference with the cold-keeping operation at the bottom of the outer groove at the inner side of the groove. . Therefore, in the present invention, interference between the assembly work of the inner tub and the cold-preserving operation at the bottom of the outer tub can be avoided.

此外，本發明之第二型態中，在前述外槽的側壁設置用以吊掛前述舉升裝置之吊掛點，並藉由前述舉升裝置，將用以連接槽屋頂部與前述內槽側板之關節部吊起，以使前述內槽側板上升。 In addition, in the second aspect of the present invention, a hanging point for hanging the lifting device is disposed on a side wall of the outer groove, and the lifting device is used to connect the groove roof portion and the inner groove. The joint portion of the side plate is lifted to raise the inner groove side plate.

本發明之第二型態中，係經由關節部將內槽側板舉升。關節部是用以連接槽屋頂部與內槽側板者，該強度相對較強(具有板厚)，故即使懸載含有內槽側板之重量，亦不會有產生壓曲等疑慮。 In the second aspect of the present invention, the inner groove side plate is lifted via the joint portion. The joint portion is a member for connecting the groove roof portion and the inner groove side plate, and the strength is relatively strong (having a plate thickness). Therefore, even if the weight of the inner groove side plate is suspended, there is no fear of buckling or the like.

此外，本發明之第三型態中，係具有：將前述舉升裝置的吊掛點依序往上方變更之步驟；以及在變更前述吊掛點之間，藉由保持手段，將包含前述關節部及前述內槽側板之槽構成構件保持在前述外槽的側壁之步驟。 Further, in a third aspect of the present invention, the step of: changing a hanging point of the lifting device to the upper side; and including the joint between the hanging points by a holding means The groove and the groove forming member of the inner groove side plate are held by the side wall of the outer groove.

以下參考圖式來說明本發明之圓筒型槽的構築方法。以下的說明中，係例示出貯藏LNG之地面式的PC(預應力混凝土)雙重殼貯槽作為圓筒型槽。 The construction method of the cylindrical groove of the present invention will be described below with reference to the drawings. In the following description, a floor-type PC (prestressed concrete) double-shell tank in which LNG is stored is shown as a cylindrical tank.

首先如第1圖所示，係進行大致圓板狀之基礎版(外槽的底部)1的施工。用以組裝後述PC壁(外槽的側壁)2之基礎部3，係以往上方突出之方式設置在基礎版1的外周緣部。此外，沿著基礎部3的內側設置內槽錨箍4。 First, as shown in Fig. 1, the construction of a substantially circular plate-shaped base plate (bottom of the outer groove) 1 is performed. The base portion 3 for assembling the PC wall (the side wall of the outer groove) 2 to be described later is provided on the outer peripheral edge portion of the base plate 1 so as to protrude upward. Further, an inner groove anchor 4 is provided along the inner side of the base portion 3.

接著如第2A圖所示，於基礎版1上組裝側襯板(外槽側板)5。側襯板5係兼作為混凝土模框。側襯板5通常為板厚約6mm的鋼材，本實施形態中，將板厚作成為約20mm或提升強度後之強化材，以提升強度。 Next, as shown in FIG. 2A, the side liner (outer groove side panel) 5 is assembled on the base plate 1. The side lining plate 5 also serves as a concrete formwork. The side lining plate 5 is usually a steel material having a thickness of about 6 mm. In the present embodiment, the thickness of the side lining plate 5 is about 20 mm or a reinforcing material after the strength is increased to increase the strength.

側襯板5係沿著基礎部3的內側而組裝。如第2B圖所示，於基礎部3的基端部設置埋入平板6，並於其上方安置側襯板5。 The side lining plate 5 is assembled along the inner side of the base portion 3. As shown in Fig. 2B, a buried plate 6 is provided at the base end portion of the base portion 3, and a side lining plate 5 is placed above it.

此外，如第2A圖所示，於基礎版1上鋪設底部襯板7。如第2B圖所示，底部襯板7的緣部係重疊於埋入平板6上而鋪設。 Further, as shown in Fig. 2A, the bottom liner 7 is laid on the base plate 1. As shown in Fig. 2B, the edge of the bottom liner 7 is laid over the buried flat plate 6 and laid.

接著如第3圖所示，進一步組裝側襯板5。此外，沿著側襯板5之基端部的內側，設置內槽側板組裝用的附腳架台8。附腳架台8為用以支撐後述內槽側板9之門型架台。該附腳架台8係以橫跨組合有複數個內槽側板9而成之圓筒狀的內槽最終 應被放下之環形區域X之方式來設置。 Next, as shown in Fig. 3, the side liner 5 is further assembled. Further, a leg stand 8 for assembling the inner groove side plate is provided along the inner side of the base end portion of the side lining plate 5. The stand stand 8 is a door type stand for supporting the inner groove side plate 9 described later. The foot stand 8 is formed by traversing a cylindrical inner groove formed by combining a plurality of inner groove side plates 9 It should be set in such a way as to drop the ring area X.

接著如第4圖所示，側襯板5從最下段依序往最上段組裝。在此，側襯板5例如被組裝至第4段為止。 Next, as shown in Fig. 4, the side lining sheets 5 are assembled from the lowermost stage to the uppermost stage in order. Here, the side lining plate 5 is assembled, for example, to the fourth stage.

然後如第5圖所示，沿著先前被組裝至第4段為止之側襯板5，於基礎部3上，PC壁2從最下段依序往最上段澆灌達例如與側襯板5相同之數目(圖中為第4段為止)而組裝。 Then, as shown in Fig. 5, along the side lining 5 which has been previously assembled to the fourth stage, on the base portion 3, the PC wall 2 is sequentially poured from the lowermost stage to the uppermost stage up to, for example, the same as the side lining 5 The number is assembled (up to the fourth paragraph in the figure).

此外，於附腳架台8上，沿著槽的周方向豎設複數個內槽側板9(亦為內槽的側壁)，並在橫方向一體地熔接此等各內槽側板9的相鄰彼此，而將此等各內槽側板9組裝為環狀結構。在此所組裝之內槽側板9，係對應於最上段(本實施形態中為第9段)。內槽側板9，是由具備有優異韌性與強度之Ni鋼材所構成。 Further, on the beading stand 8, a plurality of inner groove side plates 9 (also referred to as side walls of the inner groove) are vertically arranged along the circumferential direction of the groove, and integrally welded to each other of the inner groove side plates 9 in the lateral direction These inner groove side plates 9 are assembled into a ring structure. The inner groove side plate 9 assembled here corresponds to the uppermost stage (the ninth stage in the present embodiment). The inner groove side plate 9 is made of Ni steel having excellent toughness and strength.

接著如第6圖所示，於基礎版1的中央部組裝屋頂架台10。此外，於最上段之內槽側板9的上端部，組裝關節平板(關節部)11。此外，將高處作業車12運入基礎版1上。此外，於附腳架台8之下方的環形區域X，暫時設置珍珠岩混凝土塊或構造用輕量混凝土塊等之環形部13的構成構件。 Next, as shown in Fig. 6, the roof stand 10 is assembled at the center of the base plate 1. Further, a joint flat plate (joint portion) 11 is assembled at the upper end portion of the innermost groove side plate 9 in the uppermost stage. In addition, the upper work vehicle 12 is transported to the base plate 1. Further, a structural member of the annular portion 13 such as a perlite concrete block or a lightweight concrete block for structural use is temporarily provided in the annular region X below the beacon stand 8.

接著如第7圖所示，於屋頂架台10上裝載內槽屋頂塊，以組裝內槽屋頂(槽屋頂部)14。此外，於內槽屋頂14的外周緣部，經由關節平板11安裝最上段的內槽側板9。關節平板11係以在內槽屋頂14的外周緣部朝下方彎曲之方式形成。該關節平板11的下端緣部連接於最上段之內槽側板9的上端緣部。 Next, as shown in Fig. 7, an inner tank roof block is placed on the roof gantry 10 to assemble the inner tank roof (slot roof portion) 14. Further, on the outer peripheral edge portion of the inner tank roof 14, the uppermost inner groove side plate 9 is attached via the joint flat plate 11. The joint flat plate 11 is formed to be curved downward at the outer peripheral edge portion of the inner tank roof 14 . The lower end edge portion of the joint flat plate 11 is connected to the upper end edge portion of the innermost groove side plate 9 of the uppermost stage.

接著在較基礎版1更上方且位於內外槽間(PC壁2與內槽側板9之間)15中，在較關節平板11更上方之PC壁2，沿著槽周方向設置有複數個吊掛側千斤頂架台(吊掛點)16。吊掛側 千斤頂架台16係從既定高度的PC壁2朝槽內方側大致水平地突出。該吊掛側千斤頂架台16，係穩固且可裝卸地連結固定在例如埋入於PC壁2之錨平板等。 Then, in the PC wall 2 above the base plate 1 and between the inner and outer grooves (between the PC wall 2 and the inner groove side plate 9) 15, a plurality of cranes are arranged along the circumferential direction of the PC wall 2 above the joint plate 11 Hanging side jack stand (hanging point) 16. Hanging side The jack stand 16 protrudes substantially horizontally from the PC wall 2 of a predetermined height toward the inner side of the groove. The hanging side jack stand 16 is fixedly and detachably coupled to an anchor plate embedded in the PC wall 2, for example.

此外，於關節平板11，設置有對應於複數個吊掛側 千斤頂架台16之複數個被吊掛側千斤頂架台21。被吊掛側千斤頂架台21，係從朝內外槽間15大致水平地突出。該被吊掛側千斤頂架台21可裝卸地固定在關節平板11。此外，藉由將被吊掛側千斤頂架台21安裝於關節平板11，即使被吊掛側千斤頂架台21為強度上較為大型時，與內外槽間15相比，亦可藉由關節平板11的彎曲形狀來確保相對於PC壁2之間隙，而容易進行作業。 In addition, the joint plate 11 is provided with a plurality of hanging sides A plurality of jack side jacks 21 of the jack stand 16 are suspended. The side jack stand 21 is suspended from the inner and outer groove portions 15 substantially horizontally. The suspended side jack stand 21 is detachably fixed to the joint plate 11. Further, by attaching the suspended side jack stand 21 to the joint flat plate 11, even if the suspended side jack stand 21 is relatively large in strength, it can be bent by the joint plate 11 as compared with the inner and outer groove portions 15. The shape ensures a gap with respect to the PC wall 2, and the work is easy.

然後在組裝內槽屋頂14後，在任意之時間點中，如 第8圖所示，在內槽屋頂14上組裝外槽屋頂17。外槽屋頂17係藉由圖中未顯示的連結材與內槽屋頂14連結，並與內槽屋頂14一體地組裝。 Then after assembling the inner trough roof 14, at any point in time, such as As shown in Fig. 8, the outer trough roof 17 is assembled on the inner trough roof 14. The outer tank roof 17 is coupled to the inner tank roof 14 by a connecting material (not shown) and is integrally assembled with the inner tank roof 14.

此外，在進一步組裝側襯板5的同時，於側襯板5 的外側設置單邊鷹架(鷹架)18，並持續進行PC壁2的澆灌。PC壁2係可不採用以往般的雙足鷹架，而構成為單邊鷹架18。藉此可避免與在側襯板5的內側所進行之後述舉升作業之干涉。 Further, while the side liner 5 is further assembled, the side liner 5 is The outer side is provided with a unilateral scaffold (eagle) 18, and the PC wall 2 is continuously watered. The PC wall 2 system can be configured as a single-sided scaffold 18 without using a conventional bipedal scaffold. Thereby, interference with the lifting operation described later on the inner side of the side lining 5 can be avoided.

接著如第9圖所示，涵蓋吊掛側千斤頂架台16與被 吊掛側千斤頂架台21之間，設置舉升裝置19。舉升裝置19係如第10圖所示，係構成為中空式油壓千斤頂，並具有：吊掛於被吊掛側千斤頂架台21的下方之圓筒狀的千斤頂本體19a；以及在上下方延伸並於千斤頂本體19a可保持行程，並且經由均衡器20a將上端部卡合於吊掛側千斤頂架台16之舉升桿20。 Then, as shown in Figure 9, the hanging side jack stand 16 and the quilt are covered. A lifting device 19 is disposed between the hanging side jack stands 21. The lifting device 19 is a hollow hydraulic jack as shown in Fig. 10, and has a cylindrical jack body 19a suspended below the suspended side jack stand 21; and extending above and below The stroke is maintained in the jack body 19a, and the upper end portion is engaged with the lift lever 20 of the hanging side jack stand 16 via the equalizer 20a.

上述構成的舉升裝置19係如第9圖所示，在內外槽 間15中，以既定間隔在槽周方向設置複數個。如此，在設置舉升裝置19後，去除屋頂架台10。當去除屋頂架台10時，乃成為內槽屋頂14及外槽屋頂17之重量的一部分或全部藉由複數個舉升裝置19所支撐之狀態。 The lifting device 19 configured as described above is as shown in Fig. 9, in the inner and outer slots In the space 15, a plurality of grooves are arranged at predetermined intervals in the circumferential direction of the groove. Thus, after the lifting device 19 is installed, the roof stand 10 is removed. When the roof gantry 10 is removed, a part or all of the weight of the inner tank roof 14 and the outer tank roof 17 is supported by a plurality of lifting devices 19.

接著如第11A圖所示，藉由舉升裝置19來吊起關節 平板11，而使內槽側板9上升。具體而言，藉由將千斤頂本體19a正旋轉地驅動，使該千斤頂本體19a與被吊掛側千斤頂架台21一同帶動舉升桿20地上升，而將組裝中途的槽構成構件(在本實施形態中為包含內槽側板9、關節平板11、內槽屋頂14及外槽屋頂17)舉升。 Then, as shown in FIG. 11A, the joint is lifted by the lifting device 19. The flat plate 11 is raised to raise the inner groove side plate 9. Specifically, by driving the jack body 19a in a positively rotating manner, the jack body 19a is lifted together with the suspended side jack stand 21 to raise the lift lever 20, and the groove forming member in the middle of assembly (in the present embodiment) The lift is included in the middle groove side plate 9, the joint plate 11, the inner groove roof 14, and the outer groove roof 17).

藉由舉升裝置19所吊起之關節平板11，係用以連接 內槽屋頂14與內槽側板9者，由於強度比內槽側板9相對較強(具有板厚)，故即使懸載含有內槽側板9之重量，亦不會有產生壓曲等疑慮。亦即，下段側的內槽側板9，係對應於在槽的完成後之內容液相對較大的液壓而增加板厚，另一方面，上段側(尤其是最上段)的內槽側板9，乃對應於內容液相對較小的液壓而薄化板厚。因此，當藉由舉升裝置19將最上段的內槽側板9直接吊起時，在懸載含有下方的內槽側板9之重量時，應力集中於最上段的內槽側板9，而有最上段的內槽側板9產生挫曲之疑慮。然而，本發明中，由於藉由舉升裝置19來吊起關節平板11，所以可防止應力往最上段的內槽側板9集中，而防止伴隨於此應力集中所致之最上段的內槽側板9之壓曲。如此，可消除內槽側板9產生壓曲之疑慮，不須增加上段側的內槽側板9之板厚，而能夠達到內 槽側板9的輕量化及成本降低。 The joint plate 11 hoisted by the lifting device 19 is connected Since the inner groove side wall 14 and the inner groove side plate 9 are stronger than the inner groove side plate 9 (having a plate thickness), even if the weight including the inner groove side plate 9 is suspended, there is no fear of buckling or the like. That is, the inner groove side plate 9 on the lower stage side increases the plate thickness corresponding to the relatively large hydraulic pressure of the content liquid after the completion of the groove, and on the other hand, the upper groove side plate 9 of the upper stage side (especially the uppermost stage), The thickness is thinned corresponding to a relatively small hydraulic pressure of the content liquid. Therefore, when the uppermost inner groove side plate 9 is directly lifted by the lifting device 19, when the weight of the inner groove side plate 9 including the lower side is suspended, the stress concentrates on the uppermost inner groove side plate 9, and the most The inner groove side plate 9 of the upper stage has a fear of buckling. However, in the present invention, since the joint plate 11 is lifted by the lifting device 19, it is possible to prevent the stress from being concentrated toward the uppermost inner groove side plate 9, and to prevent the uppermost inner groove side plate due to the stress concentration. 9 of the buck. In this way, the problem of buckling of the inner groove side plate 9 can be eliminated, and the thickness of the inner groove side plate 9 on the upper side can be increased without being increased. The weight of the groove side plate 9 is reduced and the cost is reduced.

接著如第11B圖所示，藉由保持手段22，將藉由舉 升裝置19使舉升桿20上升達1行程份(本實施形態中，相當於內槽側板9單體的上下寬度)之槽構成構件保持在PC壁2。本手法中，由於進行內外槽的同時施工，所以無法進行例如等待PC壁2的完成並將舉升裝置19設置在該頂部等作業。因此，在藉由保持手段22將槽構成構件保持在PC壁2之間，必須將成為舉升裝置19的吊掛點之吊掛側千斤頂架台16的位置，變更成如第12圖所示者。 Then, as shown in FIG. 11B, by holding the means 22, The lifting device 19 raises the lift lever 20 by one stroke (in the present embodiment, the groove constituent member corresponding to the vertical width of the inner groove side plate 9 alone) is held by the PC wall 2. In this method, since the simultaneous construction of the inner and outer grooves is performed, it is not possible to perform operations such as waiting for the completion of the PC wall 2 and installing the lifting device 19 on the top. Therefore, when the groove constituting member is held between the PC walls 2 by the holding means 22, the position of the hanging side jack stand 16 which is the hanging point of the lifting device 19 must be changed to the one shown in Fig. 12. .

保持手段22係分別配置在相鄰之舉升裝置19之間。 本實施形態之保持手段22具有：設置在槽構成構件側之被吊掛側保持架台23、設置在PC壁2的側壁側之吊掛側保持架台24、以及設置在被吊掛側保持架台23與吊掛側保持架台24之間之高度調節手段25。本實施形態之高度調節手段25具有螺絲構件26。 The holding means 22 are respectively disposed between the adjacent lifting devices 19. The holding means 22 of the present embodiment includes a hanging side holder frame 23 provided on the groove forming member side, a hanging side holder frame 24 provided on the side wall side of the PC wall 2, and a hanging side holding frame table 23 A height adjusting means 25 is provided between the hanging side holding frame 24 and the hanging side. The height adjusting means 25 of the present embodiment has a screw member 26.

被吊掛側保持架台23係從關節平板11朝向內外槽 間15大致水平地成對突出。該被吊掛側保持架台23係可裝卸地固定於關節平板11。吊掛側保持架台24係從既定高度的PC壁2朝向槽內側大致水平地成對突出。該吊掛側保持架台24係穩固且可裝卸地連結固定在例如埋入於PC壁2之錨平板等。 The hanging side holding frame 23 is oriented from the joint plate 11 toward the inner and outer grooves The spaces 15 protrude substantially horizontally in pairs. The suspended side holder frame 23 is detachably fixed to the joint plate 11. The hanging side holding frame 24 protrudes substantially horizontally from the PC wall 2 of a predetermined height toward the inside of the groove. The hanging side holding frame 24 is firmly and detachably coupled and fixed to, for example, an anchor plate embedded in the PC wall 2.

螺絲構件26具有螺栓螺帽構造，並涵蓋被吊掛側保 持架台23與吊掛側保持架台24之間而設置。該螺絲構件26的螺栓部分係以夾持於被吊掛側保持架台23之間與吊掛側保持架台24之間之方式來配置，螺絲構件26的螺帽部分係卡止於被吊掛側保持架台23及吊掛側保持架台24。藉此可使槽構成構件以被 吊掛在PC壁2之方式來保持。 The screw member 26 has a bolt and nut configuration and covers the side hanging The holder 23 is provided between the holder 23 and the hanging side holder 24. The bolt portion of the screw member 26 is disposed between the suspended side holder frame 23 and the hanging side holder frame 24, and the nut portion of the screw member 26 is locked to the suspended side. The holder 23 and the hanging side holder 24 are held. Thereby, the groove forming member can be Hang in the PC wall 2 way to keep.

如此，當槽構成構件被保持在PC壁2時，如第12 圖所示，舉升裝置19的吊掛點被變更。在此之前，較佳係藉由高度調節手段25來調節槽構成構件的保持高度。此係由於槽構成構件的斜率會影響下一次的舉升之故。此外，在槽構成構件傾斜之狀態下，對於下一個內槽側板9的安裝會造成影響，且對完工後之內槽的精度亦造成影響之故。 Thus, when the groove constituent member is held on the PC wall 2, as in the 12th As shown, the lifting point of the lifting device 19 is changed. Prior to this, it is preferable to adjust the holding height of the groove constituent member by the height adjusting means 25. This is because the slope of the groove constituting member affects the next lift. Further, in the state where the groove constituting member is inclined, the installation of the next inner groove side plate 9 is affected, and the accuracy of the inner groove after completion is also affected.

由高度調節手段25所調節之槽構成構件的保持高 度，可藉由轉動螺絲構件26的螺帽部分來調節。如此，藉由使用螺絲構件26，並非階段性，而是可連續性地調節槽構成構件的高度，故可精確度佳地調節槽構成構件的高度。此外，由於槽構成構件的外周緣部係藉由複數個保持手段22所保持，所以在外周緣部的複數部位可選擇性地調節構成構件的高度，而可任意地調節槽構成構件的斜率。如此，藉由調節槽構成構件之保持高度，而提升伴隨著舉升裝置19變更至下一吊掛點時之位置調節及連接作業性。 The groove constituting member adjusted by the height adjusting means 25 is kept high The degree can be adjusted by turning the nut portion of the screw member 26. As described above, by using the screw member 26, the height of the groove constituting member can be continuously adjusted without being stepwise, so that the height of the groove constituting member can be accurately adjusted. Further, since the outer peripheral edge portion of the groove constituent member is held by the plurality of holding means 22, the height of the constituent member can be selectively adjusted at a plurality of portions of the outer peripheral edge portion, and the slope of the groove constituent member can be arbitrarily adjusted. In this manner, by adjusting the holding height of the groove constituent member, the position adjustment and the connection workability when the lifting device 19 is changed to the next hanging point are improved.

一旦調節槽構成構件的高度，則解除吊掛側千斤頂 架台16對PC壁2之固定，並將千斤頂本體19a反轉地驅動。藉此，如第12A圖及第12B圖所示，使舉升桿20及吊掛側千斤頂架台16僅上升1行程份。然後，使用設置在PC壁2的對應位置之錨平板等，再次將吊掛側千斤頂架台16可裝卸地固定在PC壁2，以變更舉升裝置19的吊掛點。 Once the height of the groove forming member is adjusted, the hanging side jack is released. The gantry 16 is fixed to the PC wall 2, and the jack body 19a is driven in reverse. Thereby, as shown in FIGS. 12A and 12B, the lift lever 20 and the hanging side jack stand 16 are raised by only one stroke. Then, using the anchor plate or the like provided at the corresponding position of the PC wall 2, the hanging side jack stand 16 is detachably fixed to the PC wall 2 again to change the hanging point of the lifting device 19.

如此，藉由千斤頂本體19a的反轉驅動使舉升桿20 上升，藉此，在變更舉升裝置19的吊掛點時，不須進行相對較重 之千斤頂本體19a側的上升和裝卸。因此，僅需進行較千斤頂本體19a相對更輕之舉升桿20側的上升和裝卸，即可容易地變更舉升裝置19的吊掛點。 Thus, the lift lever 20 is driven by the reverse rotation of the jack body 19a. Rising, whereby the relative lifting point of the lifting device 19 is not required to be relatively heavy The jack body 19a side is raised and loaded and unloaded. Therefore, the lifting point of the lifting device 19 can be easily changed by merely raising and attaching and detaching the lifting rod 20 side of the jack body 19a.

一旦結束舉升裝置19的吊掛點之變更，則解除由保 持手段22所進行之槽構成構件的保持。具體而言，卸下螺絲構件26，並從PC壁2移除下一次舉升時被吊掛側保持架台23所干涉之吊掛側保持架台24。當解除保持手段22所進行的保持時，係成為槽構成構件的重量再次藉由複數個舉升裝置19所支撐之狀態。 Once the change of the hanging point of the lifting device 19 is finished, the release is guaranteed. The holding of the groove by the means 22 constitutes a member. Specifically, the screw member 26 is removed, and the hanging side holder 24 that is interfered by the hanging side holder 23 at the next lift is removed from the PC wall 2. When the holding by the holding means 22 is released, the weight of the groove constituent member is again supported by the plurality of lifting devices 19.

在至此舉升裝置19的吊掛點變更為止之間，如第13 圖所示，藉由舉升，將下一個內槽側板9搬入至在內槽側板9的下部所形成之空間。內槽側板9的搬入係經由設置在PC壁2的下段之施工口(開口部)29來進行。於施工口29設置有搬送裝置30。 搬送裝置30係具有：從施工口29往PC壁2的外側延伸之導軌31、以及可沿著導軌31移動自如之滑輪32。 Until the lifting point of the lifting device 19 is changed, as in the 13th As shown in the figure, the next inner groove side plate 9 is carried into the space formed by the lower portion of the inner groove side plate 9 by lifting. The loading of the inner tank side plate 9 is performed via a construction port (opening) 29 provided in the lower stage of the PC wall 2. A conveying device 30 is provided at the construction port 29. The conveying device 30 has a guide rail 31 that extends from the construction port 29 to the outside of the PC wall 2, and a pulley 32 that is movable along the guide rail 31.

導軌31係沿著槽周方向(切線方向)而延伸，沿著該 導軌31被搬入於內外槽間15之內槽側板9，係在內外槽間15中經由具有沿著槽周方向所延伸之環狀導軌之第2搬運裝置(皆未圖示)，在槽周方向被搬送至既定位置。該內槽側板9係被放下至附腳架台8上，並以環狀配置在被舉升後之內槽側板9的下方。 The guide rail 31 extends along the circumferential direction of the groove (tangential direction) along the The guide rail 31 is carried into the inner groove side plate 9 of the inner and outer groove portions 15, and is disposed in the inner and outer groove portions 15 via a second conveying device (not shown) having an annular guide rail extending in the circumferential direction of the groove. The direction is transferred to the intended location. The inner groove side plate 9 is lowered onto the bead stand 8 and disposed in an annular shape below the lifted inner groove side plate 9.

接著，將配置為環狀之複數個內槽側板9彼此予以 熔接，且將上下排列之內槽側板9彼此予以熔接，而使此等內槽側板9形成為一體的圓筒狀。複數個內槽側板9彼此亦可在槽外預先在橫方向連結，在將此內槽側板容納於內外槽間15並形成為 環狀結構後，再將上下排列之內槽側板9彼此熔接。如此，藉由在作業空間的限制少之PC壁2的外側進行複數個內槽側板9彼此的熔接，可容易進行熔接作業而有效率地組裝內槽。 Next, a plurality of inner groove side plates 9 arranged in a ring shape are given to each other The inner groove side plates 9 arranged in the upper and lower sides are welded to each other, and the inner groove side plates 9 are formed in an integral cylindrical shape. The plurality of inner groove side plates 9 may be connected to each other in the lateral direction in advance in the lateral direction, and the inner groove side plates are accommodated in the inner and outer groove portions 15 and formed as After the annular structure, the inner groove side plates 9 arranged up and down are welded to each other. In this way, by welding a plurality of inner groove side plates 9 on the outer side of the PC wall 2 having a small restriction in the working space, the welding operation can be easily performed and the inner grooves can be efficiently assembled.

在安裝內槽側板9後，一旦結束舉升裝置19的吊掛 點之變更後，如第11圖所示，使舉升裝置19動作，經由關節平板11使內槽側板9僅上升1行程份，藉此，如第13圖所示地形成用以安裝下一個內槽側板9之空間。然後將應予新安裝之內槽側板9搬入至該空間。如此，藉由交互地重複進行：由舉升裝置19所進行之內槽側板9的上升、以及下一個內槽側板9對上升後之內槽側板9的下側之安裝，可將內槽側板9從最上段者依序安裝至最下段者。 After the installation of the inner groove side plate 9, once the lifting device 19 is suspended After the change of the point, as shown in Fig. 11, the lifting device 19 is operated, and the inner groove side plate 9 is raised by only one stroke via the joint flat plate 11, thereby forming the next one as shown in Fig. 13 The space of the inner groove side plate 9. Then, the newly installed inner groove side plate 9 is carried into the space. In this way, by repeating the interaction: the rise of the inner groove side plate 9 by the lifting device 19 and the attachment of the lower inner side plate 9 to the lower side of the inner groove side plate 9 after the rise, the inner groove side plate can be 9 from the top of the list to the bottom of the list.

於此等步驟中，係在基礎版1上同時進行環形部13 的保冷施工及中央部的保冷施工。環形部13的保冷施工係如第10圖所示，在附腳架台8的下方，將珍珠岩混凝土塊41A、41B、以及構造用輕量混凝土塊42組裝於底部抗冷熱緩衝材39上，然後將環形平板43安裝於該上方而進行。環形部13為最終地支撐組裝後之內槽側板9之構件，所以將環形平板43形成較厚，並且該保冷構造亦由混凝土塊等之硬質者所形成。 In these steps, the ring portion 13 is simultaneously performed on the base plate 1. Cold construction and cold preservation construction in the central part. The cold-preserving construction of the annular portion 13 is as shown in Fig. 10, and the perlite concrete blocks 41A, 41B and the lightweight concrete block 42 for construction are assembled on the bottom anti-cold heat-absorbing cushion member 39 below the beacon stand 8, and then The annular flat plate 43 is attached to the upper side. The annular portion 13 is a member that finally supports the assembled inner groove side plate 9, so that the annular flat plate 43 is formed thick, and the cold insulation structure is also formed by a rigid person such as a concrete block.

一旦環形部13的保冷施工結束，則將配置在較環形 部13更靠近槽內側之附腳架台8的腳部8a，如第13圖所示插換至環形部13的上方。腳部8a係考量到環形部13的高度而縮短，並將用以調節高度之襯板材27夾持於其間，並將附腳架台8的支撐面保持在一定高度。藉由如此之插換，干涉物會在較環形部13更靠近槽內側處消失，所以如第14圖所示，可進行將保冷材33 鋪設於基礎版1上的中央部之保冷施工。 Once the cold preservation construction of the annular portion 13 is completed, it will be arranged in a relatively ring shape. The leg portion 8a of the abutment table 8 closer to the inner side of the groove is inserted into the upper portion of the annular portion 13 as shown in Fig. 13. The leg portion 8a is shortened in consideration of the height of the ring portion 13, and the lining plate 27 for adjusting the height is sandwiched therebetween, and the support surface of the gusset table 8 is held at a certain height. By this insertion, the interference object disappears closer to the inner side of the groove than the annular portion 13, so that as shown in Fig. 14, the heat retaining material 33 can be performed. The cold construction of the central part laid on the basic plate 1.

本手法中，在如此地支撐內槽側板9之附腳架台8的下方所形成之空間中，將環形部13形成於基礎版1上。因此可避免內槽側板9的組裝作業與環形區域X中的保冷作業之干涉。此外，本手法中，在形成環形部13後，將配置在較環形部13更靠近槽內側之附腳架台8的腳部8a插換至環形部13的上方。因此，可消除槽內側中央部之與基礎版1上的保冷作業之干涉。因此可避免內槽側板9的組裝作業與基礎版1上的保冷作業之干涉，使兩作業可同時施工。 In the present method, the annular portion 13 is formed on the base plate 1 in a space formed below the bead mount 8 that supports the inner groove side plate 9. Therefore, interference between the assembly work of the inner groove side plate 9 and the cold keeping operation in the annular region X can be avoided. Further, in the present method, after the annular portion 13 is formed, the leg portion 8a of the beading table 8 disposed closer to the inner side of the groove than the annular portion 13 is inserted above the annular portion 13. Therefore, the interference of the central portion of the inner side of the groove with the cold keeping operation on the base plate 1 can be eliminated. Therefore, the interference between the assembly work of the inner groove side plate 9 and the cold preservation operation on the base plate 1 can be avoided, so that both operations can be simultaneously constructed.

該步驟中，如第14圖所示，可一邊設置單邊鷹架18，一邊將PC壁2組裝至最上段。此外，該步驟中，升降階梯34係設置在PC壁2的外部。此外，該步驟中，屋頂階梯35、珍珠岩人孔36或內外槽屋頂人孔37等係設置在外槽屋頂17。 In this step, as shown in Fig. 14, the PC wall 2 can be assembled to the uppermost stage while the single-sided eagle frame 18 is provided. Further, in this step, the elevating step 34 is provided outside the PC wall 2. Further, in this step, the roof step 35, the perlite manhole 36, or the inner and outer groove roof manholes 37 are provided on the outer tank roof 17.

接著如第15圖所示，一旦至內槽側板9的最下段之安裝結束，則撤除附腳架台8，內槽側板9之最下段的下端部係放下至環形部13上，並安裝於基礎版1上所設置之內槽錨箍4。此外，係解除由連結材所構成之與內槽屋頂14一同被舉升之外槽屋頂17和內槽屋頂14之連結，外槽屋頂17係經由圖中未顯示的頂部襯板平板，被安裝於組裝至最上段之PC壁2的上端部。 Next, as shown in Fig. 15, once the mounting to the lowermost portion of the inner groove side plate 9 is completed, the bead stand 8 is removed, and the lower end portion of the lowermost portion of the inner groove side plate 9 is lowered to the annular portion 13 and attached to the base. The inner groove anchor 4 is provided on the plate 1. Further, the connection between the trough roof 17 and the inner trough roof 14 which is constituted by the connecting material and which is lifted together with the inner trough roof 14 is released, and the outer trough roof 17 is installed via a top liner plate not shown in the drawing. The upper end portion of the PC wall 2 is assembled to the uppermost stage.

於最上段的PC壁2上，較佳係預先設置用以使外槽屋頂17上升至安裝高度之暫時架台(圖中未顯示)。然後再撤除附腳架台、舉升裝置19、吊掛側千斤頂架台16及被吊掛側千斤頂架台21等。 Preferably, on the uppermost PC wall 2, a temporary gantry (not shown) for raising the outer trough roof 17 to the installation height is provided. Then, the foot stand, the lifting device 19, the hanging side jack stand 16, and the suspended side jack stand 21 are removed.

此外，上述步驟中，如第16A圖所示，係鋪設內槽 底板38。藉此完成底部的保冷施工。於第16B圖中，符號1為基礎版，符號7為底部襯板，符號38為內槽底板，符號39為底部抗冷熱緩衝材，符號40為泡玻璃，符號41為輕量氣泡混凝土，符號41A及41B為珍珠岩混凝土塊，符號42為構等用輕型混凝土塊，符號43為環形平板。 In addition, in the above steps, as shown in Fig. 16A, the inner groove is laid. Base plate 38. This completes the cold insulation construction at the bottom. In Fig. 16B, the symbol 1 is the basic plate, the symbol 7 is the bottom liner, the symbol 38 is the inner groove bottom plate, the symbol 39 is the bottom anti-cold heat buffer material, the symbol 40 is the bubble glass, and the symbol 41 is the lightweight bubble concrete, the symbol 41A and 41B are perlite concrete blocks, symbol 42 is a lightweight concrete block for construction, and symbol 43 is a circular flat plate.

然後進行PC壁2的張設施工。在經過圖中未顯示之內槽施工口的關閉、圖中未顯示之泵筒的設置後，進行注水以實施耐壓、氣密試驗。 Then, the facility of the PC wall 2 is carried out. After the installation of the inner tank construction port not shown in the figure and the installation of the pump cylinder not shown in the figure, water injection is performed to carry out the pressure resistance and airtightness test.

最後如第17圖所示，將保冷材44(例如珍珠岩)充填於內外槽間15來進行內外槽間保冷施工，然後經過塗裝施工、配管保冷施工，而構築圓筒型槽100。 Finally, as shown in Fig. 17, the cold-preserving material 44 (for example, perlite) is filled in the inner and outer tanks 15 to perform cold-insulation between the inner and outer tanks, and then the cylindrical tank 100 is constructed by coating construction and piping cooling construction.

第18圖係顯示本發明實施形態之構築方法之整體的流程圖。第18圖中，附加陰影線之步驟(基礎、PC壁、側PUF)為由土木業者所進行之步驟。如第18圖所示，在進行基礎的施工後，較PC壁更先進行襯板(側襯板5)的施工，並且在PC壁構築中，進行屋頂、內槽及底板之施工，所以可大幅縮短工期。 Fig. 18 is a flow chart showing the entire construction method of the embodiment of the present invention. In Fig. 18, the step of adding hatching (base, PC wall, side PUF) is a step performed by the civil engineer. As shown in Fig. 18, after the foundation construction, the construction of the lining (side lining 5) is carried out earlier than the PC wall, and the construction of the roof, the inner tank and the bottom plate is carried out in the PC wall construction, so Significantly shorten the construction period.

如此，於上述本實施形態中，具有：在混凝土製外槽的內側，交互地重複進行由舉升裝置所進行之內槽側板的上升、以及下一個內槽側板對前述上升後之內槽側板的下側之安裝，以組裝金屬製的內槽之步驟；在圓筒型槽100的構築方法中係具有：以橫跨基礎版1上且為所組裝之內槽應被放下之環形區域X之方式，設置用以支撐內槽側板8之附腳架台8之步驟；在附腳架台8的下方，將用以支撐所組裝之內槽之環形部13形成於環形區域X之步驟；以及在環形部13的形成後，將配置在較環 形部13更靠近槽內側之附腳架台8的腳部8a，插換至環形部13的上方之步驟。藉由採用該手法，可使將保冷材鋪設於基礎版1之保冷作業不會成為作業瓶頸。因此，可消除內槽的組裝作業與基礎版1的保冷作業之干涉而縮短工期。 As described above, in the above-described embodiment, the inner groove side plate by the lifting device is alternately repeated on the inner side of the concrete outer groove, and the inner groove side plate is lifted by the next inner groove side plate. The lower side is mounted to assemble the inner groove of the metal; in the method of constructing the cylindrical groove 100, there is an annular area X which is placed across the base plate 1 and the inner groove to be assembled is to be lowered. In a manner of providing a foot stand 8 for supporting the inner groove side plate 8; a step of forming an annular portion 13 for supporting the assembled inner groove in the annular region X below the bead stand 8; After the formation of the annular portion 13, it will be arranged in a relatively ring The portion 13 is closer to the leg portion 8a of the beading table 8 on the inner side of the groove, and is inserted into the upper portion of the annular portion 13. By adopting this method, the cold storage operation in which the cold storage material is laid on the base plate 1 does not become a work bottleneck. Therefore, it is possible to eliminate the interference between the assembly work of the inner tank and the cold storage operation of the basic plate 1 and shorten the construction period.

以上係參考圖式來說明本發明的較佳實施形態，但 本發明並不限定於上述實施形態。上述實施形態中所示之各構成構件的各形狀或組合等僅為一例，在不脫離本發明之主旨的範圍內，可根據設計要求等來進行各種變更。 The preferred embodiments of the present invention have been described above with reference to the drawings, but The present invention is not limited to the above embodiment. The respective shapes, combinations, and the like of the respective constituent members shown in the above-described embodiments are merely examples, and various modifications can be made according to design requirements and the like without departing from the gist of the invention.

例如亦可採用第19圖及第20圖所示之手法。第19 圖及第20圖中，對於與上述實施形態同一或同等的構成部分，係附加同一符號並簡化或省略該說明。 For example, the methods shown in Figs. 19 and 20 can also be employed. 19th In the drawings and the drawings, the same or equivalent components as those in the above-described embodiments are denoted by the same reference numerals, and the description is simplified or omitted.

於第19圖所示之其他實施形態中，於保持手段22 之成對的吊掛側保持架台24，隔著可上下通過之間隙來配置被吊掛側保持架台23。然後遍及成對之吊掛側保持架台24的上表面來配置保持塊B，並將螺絲構件26卡合於該保持塊B，藉此由保持手段22承受槽構成構件的重量。根據該保持手段22，即使藉由舉升，被吊掛側保持架台23與吊掛側保持架台24亦不會干涉。 因此，不須如上述實施形態般在舉升之前須去除吊掛側保持架台24，所以容易進行舉升裝置19的吊掛點之變更作業。 In another embodiment shown in FIG. 19, in the holding means 22 The pair of hanging side holding frames 24 are arranged with the hanging side holding frame 23 interposed therebetween. Then, the holding block B is disposed over the upper surface of the pair of hanging side holding frames 24, and the screw member 26 is engaged with the holding block B, whereby the weight of the groove constituent member is received by the holding means 22. According to the holding means 22, the suspended side holding frame 23 and the hanging side holding frame 24 do not interfere even by lifting. Therefore, it is not necessary to remove the hanging side holding frame 24 before lifting, as in the above embodiment, so that it is easy to change the hanging point of the lifting device 19.

此外，於第20圖所示之其他實施形態中，係在PC 壁2另外設置承受槽構成構件的重量之舉升裝置19B來取代保持手段22，並一邊交互地藉由舉升裝置19A及舉升裝置19B來保持槽構成構件，一邊使該槽構成構件上升。此外，由於舉升裝置19A、19B本身可調節槽構成構件的高度，所以亦可不另外設置如 螺絲構件26般之高度調節手段。 In addition, in the other embodiment shown in FIG. 20, it is in the PC. The wall 2 is provided with a lifting device 19B that receives the weight of the groove constituting member instead of the holding means 22, and the groove constituting member is held by the lifting device 19A and the lifting device 19B alternately, and the groove constituting member is raised. In addition, since the lifting devices 19A, 19B themselves can adjust the height of the groove forming member, they may not be separately provided. A height adjustment means like the screw member 26.

此外，例如最上段的內槽側板9之組裝作業，可在舉升作業後(亦即在內槽側板9之前先組裝關節平板11)進行。 Further, for example, the assembly work of the uppermost inner groove side plate 9 can be performed after the lifting operation (that is, assembling the joint flat plate 11 before the inner groove side plate 9).

此外，例如可與舉升作業同時地進行內槽屋頂14、外槽屋頂17的組裝。 Further, for example, the assembly of the inner tank roof 14 and the outer tank roof 17 can be performed simultaneously with the lifting operation.

此外，例如使舉升桿20與吊掛側千斤頂架台16上升之手法，並不限定於千斤頂本體19a的反轉驅動，因情況的不同，亦可藉由其他吊起裝置來實施。 Further, for example, the method of raising the lift lever 20 and the hanging side jack stand 16 is not limited to the reverse driving of the jack body 19a, and may be implemented by another lifting device depending on the situation.

此外，例如在上述實施形態中，係說明於舉升裝置19的每1行程中進行內槽側板9的組裝作業，但亦可於舉升裝置19的每1行程中進行複數個內槽側板9的組裝作業。 Further, for example, in the above-described embodiment, the assembly operation of the inner tank side plate 9 is performed in each stroke of the lift device 19. However, a plurality of inner groove side plates 9 may be performed in each stroke of the lift device 19. Assembly work.

此外，例如附腳架台8之腳部8a的插換，不僅是上述之舉升關節平板11之手法，亦可適用先前技術之直接舉升內側槽板之手法。 Further, for example, the insertion of the leg portion 8a of the foot stand 8 is not only the above-described method of lifting the joint plate 11, but also the technique of directly lifting the inner groove plate of the prior art.
