Description
本發明係有關於一種建構圓形接地線下支撐的方法，該圓形接地線下支撐是在使用裝在鑽吊機(auger crane)上的開挖螺桿來進行機械化立桿工作的情形下用於支撐及固定電線桿(utility pole)的，且更特別的是，有關於一種使用可延伸之液壓開挖螺桿建構高強度圓形接地線下支撐的方法，藉此增加圓形接地線下支撐埋在地下的表面積以改善圓形接地線下支撐的拔出阻力(pull-out resistance)，使用藉由液壓壓力自動伸出的開挖螺桿依序挖掘用於埋設圓形接地線下支撐的區段與接地線棍的介入區段以有效獲得用於支撐有高重量之電線桿的力而只通過單一圓形接地線下支撐即可成為大容量配電設備的一部份，以及用該可延伸之液壓開挖螺桿可迅速有效地建構該圓形接地線下支撐。The present invention relates to a method of constructing a circular grounding wire support which is used in the case of using a digging screw mounted on an auger crane for mechanized pole work. For supporting and fixing utility poles, and more particularly, a method for constructing a high-strength circular grounding wire support using an extendable hydraulic excavation screw, thereby increasing the circular grounding wire under support The surface area buried in the ground is used to improve the pull-out resistance of the support under the circular grounding wire, and the excavating screw automatically extended by the hydraulic pressure is used to sequentially excavate the area for burying the support under the circular grounding wire. The segment of the segment and the grounding bar can be used as part of a large-capacity power distribution device by effectively obtaining a force for supporting a high-powered utility pole and supporting only under a single circular grounding wire, and can be extended by the same. The hydraulic excavation screw can quickly and effectively construct the circular grounding wire under the support.
通常在建構電力輸配電線路(electric power transmission and distribution line)及通信線路時，如果安裝電線桿以及接上電線與通信電纜，則安裝接地線供加強電線與通信電纜的不平衡張力以防電線桿傾斜或倒下。此外，在安裝接地線的時候，首先是用人力或機器進行埋設接地線下支撐的挖掘工作。之後，將接地線下支撐埋在挖掘地點上，以及通過電線棍將接地線連接至電線桿。Usually, when constructing electric power transmission and distribution lines and communication lines, if installing poles and connecting wires and communication cables, install grounding wires to strengthen the unbalanced tension between the wires and the communication cables to prevent wires. The lever is tilted or fallen down. In addition, when installing the grounding wire, firstly, the excavation work of the underground grounding support is carried out by manpower or machine. After that, bury the ground wire support at the excavation site and connect the ground wire to the pole by wire rods.
習知接地線下支撐與用於建構接地線下支撐的方法已揭示於韓國專利第710649號、第738279號、第740013號及第761778號，該等專利的申請人與本發明的相同。The conventional grounding wire support and the method for constructing the ground wire lower support are disclosed in Korean Patent Nos. 710649, 738279, 740013, and 761778, the applicants of which are the same as the present invention.
用於最近接地線下支撐建構法的接地線下支撐包含兩種類型，第一種是長度為0.7米及1.2米的矩形接地線下支撐，另一種是直徑有43米及62米以及長度與上述矩形接地線下支撐相同的圓形電線下支撐。The grounding wire support for the recent grounding support construction method consists of two types, the first one is a rectangular ground wire with a length of 0.7 m and 1.2 m, and the other is a diameter of 43 m and 62 m and the length and The rectangular ground wire below supports the same circular wire under the support.
接地線下支撐在大小及形狀上的差異是基於待裝上電線桿之設備的設計負載以便根據設計負載的要求完成有足夠張力的設備。隨著工業領域的發展與需要電力的設施數大幅增加，供電系統已變為大容量。The difference in size and shape of the grounding wire support is based on the design load of the equipment to be fitted with the utility pole to complete the equipment with sufficient tension according to the design load requirements. With the development of the industrial field and the number of facilities requiring electricity, the power supply system has become a large capacity.
由本發明申請人引進的上述圓形接地線下支撐是用圓形接地線下支撐取代習知矩形接地線下支撐的新穎技術。The circular grounding wire lower support introduced by the applicant of the present invention is a novel technique of replacing the lower rectangular grounding wire support with a circular grounding wire lower support.
更詳細言之，韓國配電系統的配電電壓(distribution voltage)為22.9kV，不過已有人做出提高配電電壓的研究用來增強大容量的配電供給。In more detail, the distribution voltage of the Korean power distribution system is 22.9 kV, but studies have been made to increase the distribution voltage to enhance the large-capacity power distribution.
因此，家庭會進行用於使配電電壓由110V升高至220V的建構，之後，將韓國配電電壓由6.6kV改變成22.9kV。Therefore, the family will construct the distribution voltage from 110V to 220V, and then change the Korean distribution voltage from 6.6kV to 22.9kV.
由於配電電壓被改變，因此用於建構電力設備所需要的所有材料也應改變，而就此情形而言，用於支撐電力設備的電線桿，用於支撐電線桿的接地線，以及用於固定接地線的接地線下支撐都是極為重要的材料。Since the distribution voltage is changed, all the materials required to construct the power equipment should also be changed, and in this case, the utility pole for supporting the electric equipment, the grounding wire for supporting the utility pole, and the fixed grounding The underlying ground wire support is an extremely important material.
鑑於配電線路的路線，配置在電線桿上的電線及相關材料是在設計負載的考量下加上，使得它們的重量是在接地線耐得住配電線路之張力的範圍內以免破壞電線桿。因此，在解決上述問題時，以更高的程度整合配置在一配電線路(亦即，配電線路的路線)上的電力設備相關材料。In view of the route of the distribution line, the wires and related materials disposed on the utility pole are added under the consideration of the design load, so that their weight is within the range that the grounding wire can withstand the tension of the distribution line to avoid damaging the utility pole. Therefore, in solving the above problems, the power equipment related materials disposed on a distribution line (that is, the route of the distribution line) are integrated to a higher degree.
例如，假設，有一區域(其中要豎立電線桿於道路兩旁以及配置配電線路於電線桿上)，此時，如果有可能進行高強度接地線的建構，可將待配置於道路兩旁的重負載設備整合於道路之一側。隨著電力需求增長，安裝大容量的電力線路以改善電力供給，以及安裝電力設備會破壞道路的容貌以及會因佔用土地而破壞周遭環境。隨著變成電力設備有大容量以及負載也在增加，因此確實有需要開發具有高強度的接地線下支撐。For example, suppose that there is an area (where the utility pole is to be erected on both sides of the road and the distribution line is placed on the utility pole). At this time, if it is possible to construct the high-strength grounding line, the heavy-duty equipment to be placed on both sides of the road can be disposed. Integrated on one side of the road. As power demand grows, installing large-capacity power lines to improve power supply, as well as installing electrical equipment, can ruin the appearance of the road and can damage the surrounding environment by occupying land. As the power equipment becomes large in capacity and the load is also increasing, there is a real need to develop a grounding line support with high strength.
另外，目前的配電建構裝有兩條或更多電力線路與供通信線路共用的設施，從而在一接地線耐不住電力線路及通信線路所施加的張力時，另外加裝電線，這種事常發生。然而，如果進行高強度接地線的建構，接地線建構只施加一次高張力，藉此只用單一接地線下支撐即可實質耐得住根據配電設備及通信線路共用設施之增加數得到的材料重量與線路的張力。因此，絕對有需要開發高強度接地線下支撐。In addition, the current power distribution construction is equipped with two or more power lines and facilities shared by the communication lines, so that when a ground line cannot withstand the tension applied by the power lines and communication lines, additional wires are added. Often occurs. However, if the construction of the high-strength grounding wire is carried out, the grounding wire construction only applies a high tension once, so that only a single grounding wire can be used to support the weight of the material obtained according to the increase of the power distribution equipment and the communication line sharing facility. With the tension of the line. Therefore, there is absolutely a need to develop high-strength ground wire support.
因此，基於先前技術的上述問題，已做出本發明，以及本發明的目標是要提供一種使用可延伸之液壓開挖螺桿建構高強度圓形接地線下支撐的方法，其中提供直徑至少72公分或更多的一圓形接地線下支撐，以及使用裝在鑽吊機上的該可延伸之液壓開挖螺桿來形成用於埋設該圓形接地線下支撐的一開挖區段，該開挖區段包含一接地線下支撐埋設區段以及利用藉由液壓壓力擴張及收縮之數個輔助挖刀部件來形成的一接地線棍介入區段，藉此大幅增加對著地面及土壤的表面積供埋設尺寸擴大的圓形接地線下支撐以便改善拔出阻力，同時用有數個可延伸之液壓輔助刀片部件的開挖螺桿以機械方式進行該開挖程序而沒有任何人工操作，藉此取代使用延伸人工操作用之機器建構圓形接地線下支撐的現有方法以提供快速的建構時間與高品質的建構成果。Accordingly, the present invention has been made based on the above problems of the prior art, and an object of the present invention is to provide a method of constructing a high-strength circular grounding wire support using an extendable hydraulic excavation screw, wherein a diameter of at least 72 cm is provided.

下文是用附圖詳述用於建構圓形接地線下支撐的方法。The following is a detailed description of the method for constructing a circular ground wire lower support using the drawings.
第1圖的透視圖係圖示用於本發明的液壓開挖螺桿，第2圖的透視圖圖示用於本發明的圓形接地線下支撐。The perspective view of Fig. 1 illustrates a hydraulic excavation screw for use in the present invention, and the perspective view of Fig. 2 illustrates a circular ground line support for the present invention.
如圖示，用於本發明的液壓開挖螺桿20包含輔助挖刀部件21、21'，彼等係藉由鑽吊機所施加之液壓壓力而可水平擴張及收縮，開挖螺桿20係安裝於該鑽吊機且沿著外周面裝上螺旋螺桿部件22。As shown, the hydraulic excavation screw 20 used in the present invention includes auxiliary digging members 21, 21' which are horizontally expandable and contractible by hydraulic pressure applied by the drilling and hoisting machine, and the excavating screw 20 is installed. The screw crane 22 is attached to the hoisting machine and along the outer peripheral surface.
此外，用於本發明的圓形接地線下支撐10有至少72公分或更多的直徑且包含固定彼之中心的垂直延伸接地線棍11。Further, the circular ground wire lower support 10 for use in the present invention has a diameter of at least 72 cm or more and includes a vertically extending grounding bar 11 that is fixed to the center thereof.
在有圓形接地線下支撐10及液壓開挖螺桿20的狀態下，將液壓開挖螺桿20裝上鑽吊機，然後，開挖裝有電線桿的場地。In a state where the circular grounding wire is supported by the lower 10 and the hydraulic excavating screw 20, the hydraulic excavating screw 20 is attached to the drilling and hoisting machine, and then the site where the electric pole is installed is excavated.
此時，是在輔助挖刀部件21、21'不擴張的情形下，用液壓開挖螺桿20開挖場地，藉此移除有接地線棍11的介入區段。At this time, in a case where the auxiliary cutter members 21, 21' are not expanded, the site is excavated by the hydraulic excavation screw 20, whereby the intervention section having the grounding bar 11 is removed.
在此狀態下，將液壓開挖螺桿20移到與由開挖程序形成的接地線棍拔出區段30毗鄰的場所，然後，在輔助挖刀部件21、21'不擴張的狀態下，進行第一接地線下支撐開挖程序。In this state, the hydraulic excavating screw 20 is moved to a position adjacent to the grounding bar pull-out section 30 formed by the excavation process, and then, in a state where the auxiliary digging members 21, 21' are not expanded, The first grounding wire supports the excavation procedure.
在進行第一接地線下支撐開挖程序時，根據場地及地質的狀態以及卵礫石層(gravel layer)的存在，施加於液壓開挖螺桿20的開挖壓力會很強，因此，在輔助挖刀部件21、21'由液壓開挖螺桿20不水平擴張的狀態下，進行第一接地線下支撐開挖程序不會增加液壓開挖螺桿20及鑽吊機的負載。When the first grounding line supports the excavation procedure, the excavation pressure applied to the hydraulic excavation screw 20 is strong according to the site and geological state and the presence of the gravel layer, and therefore, the auxiliary digging is performed. In the state where the cutter members 21, 21' are not horizontally expanded by the hydraulic excavation screw 20, the first ground line lower support excavation procedure does not increase the load of the hydraulic excavation screw 20 and the drill crane.
在第一接地線下支撐開挖程序完成後，施加液壓壓力至液壓開挖螺桿20的輔助挖刀部件21、21'，使得輔助挖刀部件21、21'由液壓開挖螺桿20水平擴張。在輔助挖刀部件21、21'擴張後，用液壓開挖螺桿20進行第二接地線下支撐開挖程序以便延伸第一開挖程序的開挖區段。就此情形而言，施加至液壓開挖螺桿20及鑽吊機的負載會相對減少，藉此可溫和及迅速地完成下支撐埋設區段40的開挖程序。After the completion of the support excavation procedure under the first grounding line, hydraulic pressure is applied to the auxiliary digging members 21, 21' of the hydraulic excavation screw 20, so that the auxiliary digging members 21, 21' are horizontally expanded by the hydraulic excavating screw 20. After the auxiliary digging members 21, 21' are expanded, the second grounding line support excavation procedure is performed by the hydraulic excavation screw 20 to extend the excavation section of the first excavation program. In this case, the load applied to the hydraulic excavation screw 20 and the drill hoist is relatively reduced, whereby the excavation procedure of the lower support burying section 40 can be completed gently and quickly.
接下來，進行將圓形接地線下支撐10***下支撐埋設區段40的***程序，以及通過形成於下支撐埋設區段40一旁之接地線棍拔出區段30向地面拔出圓形接地線下支撐10之接地線棍11的拔出程序。Next, an insertion procedure for inserting the circular ground wire lower support 10 into the lower support buried section 40 is performed, and a circular ground is pulled out to the ground through the grounding bar pull-out section 30 formed on the side of the lower support buried section 40. The pull-out procedure of the grounding bar 11 of the offline support 10.
如上述，根據本發明，用尺寸加長的接地線下支撐來增加抵抗受挖掘埋土及埋砂的表面積，從而，用固定於接地線下支撐上的接地線棍來支撐電線桿的力會變成很強，即使為了提高配電電壓而增加各種材料的重量，此法仍然有效。由於可額外安裝與電力設備數有關的材料於現有線路上，可設計整合的大容量配電線路，從而可解決因安裝電力設備而破壞道路容貌的問題以及實質減少佔用土地的面積。此外，由於高強度接地線建構是用一個接地線下支撐達成，因此不需要額外的接地線建構，以及用藉由鑽吊機所施加之液壓壓力而自動擴張的輔助挖刀部件可迅速有效地挖掘下支撐埋設區段與接地線棍介入區段，從而具有優異的可使用性與經濟效益以及取代使用延伸人工操作用之機器建構圓形接地線下支撐的現有方法。As described above, according to the present invention, the lengthening of the grounding wire is used to increase the surface area against the excavated buried and buried sand, and thus the force of supporting the utility pole by the grounding bar fixed to the lower support of the grounding wire becomes Very strong, even if the weight of various materials is increased in order to increase the distribution voltage, this method is still effective. Since additional materials related to the number of electrical equipment can be additionally installed on existing lines, an integrated large-capacity distribution line can be designed, thereby solving the problem of destroying the road appearance due to the installation of electric equipment and substantially reducing the area occupied by the land. In addition, since the construction of the high-strength grounding wire is achieved by a grounding wire support, no additional grounding wire construction is required, and the auxiliary cutting tool component that is automatically expanded by the hydraulic pressure exerted by the drilling and hoisting machine can be quickly and effectively Excavating the lower support section and the grounding rod intervention section, which has excellent workability and economical efficiency, and replaces the existing method of constructing a circular ground line support using an extended manual operation machine.
