しかし、アプローチの構築中では、構築しようとするアプローチの幅に加えてアプローチの両脇にも歩道幅を狭くして作業帯を確保する必要があり、工事の開始時から完了時まで長期間にわたって車線規制をする必要がある。例えば、既設道路が片側２車線である場合には、中央寄りの車線を封鎖して片側１車線に規制する必要がある。   However, during the construction of the approach, it is necessary to secure a work zone by narrowing the sidewalk width on both sides of the approach in addition to the width of the approach to be constructed. Lane regulation is necessary. For example, when the existing road has two lanes on one side, it is necessary to block the lane closer to the center and restrict it to one lane on one side.

そこで、本発明は、アプローチの工事開始時から完了時まで常に車線規制せずともアプローチを構築することができるアプローチ構築方法を提供することを目的とする。   Therefore, an object of the present invention is to provide an approach construction method capable of constructing an approach without always restricting the lane from the start to completion of the approach construction.

以上の課題を解決するため、請求項１に係る発明では、道路に沿ってアプローチを構築するアプローチ構築方法において、２列の覆工を間隔をおいて道路に沿って施工した後に前記覆工の間及び前記覆工の下を道路に沿って溝状に掘削し、その掘削した溝の底に基礎を施工し、前記基礎の上に２列の擁壁を前記覆工よりも上方に延出するよう前記道路に沿って立設し、前記覆工を撤去した後に前記２列の擁壁の間隔を広げ、前記２列の擁壁の間に床版を架設することを特徴とする。 In order to solve the above problems, in the invention according to claim 1, in the approach construction method for constructing an approach along a road, the lining is performed after constructing two rows of lining along the road at intervals. And under the lining are excavated into a groove along the road, a foundation is constructed at the bottom of the excavated groove, and two rows of retaining walls are extended above the foundation above the lining. It is characterized by standing along the road so as to exit, and after removing the lining, the interval between the two rows of retaining walls is widened, and a floor slab is installed between the two rows of retaining walls.

請求項２に係る発明では、前記床版の下であって前記２列の擁壁の間の中空を充填材で充填する。   In the invention according to claim 2, the space between the two retaining walls under the floor slab is filled with a filler.

本発明によれば、擁壁を立設している間は覆工が設置されているため、覆工の上を車線として確保することができ、アプローチの工事開始時から完了時まで常に車線規制を行わなくとも済む。
また、覆工を撤去してからアプローチが完成するまでの工程は、２列の擁壁の間隔を広げる工程と、２列の擁壁の間に床版を設置してアプローチの路面を構築する工程だけであるから、車線規制を長時間必要としない。 According to the present invention, since the lining is installed while the retaining wall is erected, it is possible to secure the lining on the lining as a lane, and always control the lane from the start to the completion of approach construction. You don't have to.
Also, the process from the removal of the lining to the completion of the approach is the process of widening the spacing between the two rows of retaining walls and constructing the road surface of the approach by installing a floor slab between the two rows of retaining walls Since it is only a process, lane regulation is not required for a long time.

以下に、本発明を実施するための最良の形態について図面を用いて説明する。但し、以下に述べる実施形態には、本発明を実施するために技術的に好ましい種々の限定が付されているが、発明の範囲を以下の実施形態及び図示例に限定するものではない。また、以下に挙げる寸法は本発明の理解を助けるための一例であり、本発明を下記寸法に限定するものではない。   The best mode for carrying out the present invention will be described below with reference to the drawings. However, although various technically preferable limitations for implementing the present invention are given to the embodiments described below, the scope of the invention is not limited to the following embodiments and illustrated examples. The dimensions listed below are examples for helping understanding of the present invention, and the present invention is not limited to the following dimensions.

図１に示すような既設の道路１にアプローチを構築する方法について説明する。この道路１は別の道路に交差し、その別の道路と立体交差する高架道路の橋梁部が構築され、構築しようとするアプローチは橋梁部の端から道路１の路面に接続するものである。   A method for constructing an approach on an existing road 1 as shown in FIG. 1 will be described. This road 1 intersects with another road, and a bridge portion of an elevated road that is three-dimensionally intersected with the other road is constructed.

アプローチの構築工事が行われる前では、道路１が片側２車線の道路であって、道路１の両脇に歩道２が設けられ、車道４の中央に中央分離帯３が設けられている。寸法の一例として挙げると、道路１の全体の幅が２５ｍであり、植え込み部を含む歩道２の幅が４．２５ｍであり、車道４の片側２車線分の幅が７．５ｍであり、中央分離帯３の幅が１．５ｍである。   Before the construction of the approach is performed, the road 1 is a road with two lanes on one side, a sidewalk 2 is provided on both sides of the road 1, and a median strip 3 is provided in the center of the road 4. As an example of the dimensions, the width of the entire road 1 is 25 m, the width of the sidewalk 2 including the planting part is 4.25 m, the width of two lanes on one side of the road 4 is 7.5 m, The width of the separation band 3 is 1.5 m.

まず、車道４の幅を歩道２側に拡張し、歩道２の幅を縮小する。例えば、歩道２の幅を４．２５ｍから２．８ｍに縮小する。   First, the width of the roadway 4 is expanded to the sidewalk 2 side, and the width of the sidewalk 2 is reduced. For example, the width of the sidewalk 2 is reduced from 4.25 m to 2.8 m.

次に、図２に示すように、夜間等に一時的に車線を規制して、２列の覆工を間隔をおいて道路１に沿って施工する。具体的には、車道４の両側に片側１車線５を確保し、その車線５の内側に沿って背板材、矢板、杭等を地盤に打ち込むことで２列の山留め６をアプローチ構築区間にわたって平行に構築する。そして、受桁７を山留め６の上端から道路１の中央に向かって延出するように設置し、アプローチ構築区間にわたって複数の覆工板８を車線５の路面と面一となるように受桁７の上に配設していく。以上のように道路１の中央を挟んで２列の覆工を施工することによって、片方の覆工の覆工板８の上と外側の車線５とによって片側２車線分を確保することができる。なお、片側の覆工ともう片側の覆工との間の間隔Ａは６．４ｍである。   Next, as shown in FIG. 2, the lane is temporarily restricted at night or the like, and two rows of linings are constructed along the road 1 at intervals. Specifically, one lane 5 on one side is secured on both sides of the roadway 4, and backboard materials, sheet piles, piles, etc. are driven into the ground along the inside of the lane 5, so that two rows of mountain fasteners 6 are parallel across the approach construction section. To build. And the girder 7 is installed so that it may extend toward the center of the road 1 from the upper end of the retaining ring 6, and a plurality of lining boards 8 are flush with the road surface of the lane 5 over the approach construction section. 7 is arranged on top. By constructing two rows of lining across the center of the road 1 as described above, it is possible to secure two lanes on one side by the upper lining plate 8 and the outer lane 5 of one lining. . The distance A between the lining on one side and the lining on the other side is 6.4 m.

次に、図３に示すように、覆工板８の上にフェンス３２をアプローチ構築区間にわたって２列の配列し、２列の山留め６の間をアプローチ構築区間にわたって溝状に掘削する。ここで、覆工板８の下も掘削する。必要に応じて、受桁７を支柱３１で支えるとともに、切梁及び腹起しを架設して山留め６を支える。   Next, as shown in FIG. 3, the fences 32 are arranged in two rows over the approach construction section on the lining plate 8, and the space between the two rows of mountain retaining 6 is excavated in a groove shape over the approach construction section. Here, the bottom of the lining plate 8 is also excavated. If necessary, the beam support 7 is supported by the support column 31 and the beams 6 and the erection are erected to support the mountain stopper 6.

次に、図４に示すように、掘削溝の底に基礎を施工する。具体的には、杭が必要となる場合には掘削溝の底から地盤へ基礎杭９を打設し、掘削溝の底に基礎スラブ１０を打設する。掘削溝の底に基礎を施工するに際しては、図６に示すように、アプローチ構築区間にわたって複数の基礎スラブ１０を配列させる。   Next, as shown in FIG. 4, a foundation is constructed at the bottom of the excavation groove. Specifically, when a pile is required, the foundation pile 9 is driven from the bottom of the excavation groove to the ground, and the foundation slab 10 is driven at the bottom of the excavation groove. When constructing the foundation at the bottom of the excavation groove, as shown in FIG. 6, a plurality of foundation slabs 10 are arranged over the approach construction section.

基礎の構築後、基礎スラブ１０の上に滑りシート１１を敷設する。ここで、滑りシート１１はフッ素樹脂（例えば、テフロン（登録商標））からなるものである。なお、各図において、滑りシート１１を示すために滑りシート１１を他のもの比較して厚く図示している。   After the foundation is constructed, the sliding sheet 11 is laid on the foundation slab 10. Here, the sliding sheet 11 is made of a fluororesin (for example, Teflon (registered trademark)). In addition, in each figure, in order to show the sliding sheet 11, the sliding sheet 11 is shown thickly compared with another.

次に、図５及び図６に示すように２列の鉄筋コンクリート製の擁壁１２を基礎スラブ１０上に立設し、２列の擁壁１２をアプローチ構築区間にわたって互いに平行となるように構築する。ここで、擁壁１２は、基礎スラブ１０の上に構築された土台部１３と、その土台部１３の上に立てられた壁部１４と、壁部１４の上部から道路１の中央に向かって延出した受部１５とからなる。   Next, as shown in FIGS. 5 and 6, two rows of reinforced concrete retaining walls 12 are erected on the foundation slab 10, and the two rows of retaining walls 12 are constructed to be parallel to each other over the approach construction section. . Here, the retaining wall 12 includes a base portion 13 constructed on the foundation slab 10, a wall portion 14 standing on the base portion 13, and an upper portion of the wall portion 14 toward the center of the road 1. It consists of the receiving part 15 extended.

擁壁１２を構築するに際して、壁部１４を覆工板８の中央側の縁に沿わせるように設置し、更に壁部１４を掘削溝から覆工板８よりも上に延出させるよう設置する。図６に示すように、擁壁１２を構築するに際して、沿道側から擁壁１２を見て、１列の擁壁１２を基礎スラブ１０の上で分割するように設置し、隣り合う基礎スラブ１０に擁壁１２を架け渡すように擁壁１２を設置する。また、擁壁１２を構築するに際して、沿道側から擁壁１２を見て、壁部１４の上縁及び受部１５がアプローチの傾斜に沿うように傾斜させる。そのため、図７に示すように道路１に接続される妻部では擁壁１２の壁部１４の高さが道路１の路面とほぼ同じになり、反対側の橋梁部に接続される妻部では擁壁１２の壁部１４の高さが橋梁部の路面とほぼ同じになる。また、片側の土台部１３ともう一方の土台部１３との間隔を１ｍにする。なお、図８に示すように、擁壁１２の壁部１４を厚くして、壁部１４の内部に空洞１７を形成しても良い。   When the retaining wall 12 is constructed, the wall portion 14 is installed along the central edge of the lining plate 8, and the wall portion 14 is further extended above the lining plate 8 from the excavation groove. To do. As shown in FIG. 6, when the retaining wall 12 is constructed, the retaining wall 12 is viewed from the side of the road and is installed so as to divide the row of retaining walls 12 on the foundation slab 10. The retaining wall 12 is installed so as to span the retaining wall 12. Further, when the retaining wall 12 is constructed, the retaining wall 12 is viewed from the side of the road, and the upper edge of the wall portion 14 and the receiving portion 15 are inclined along the inclination of the approach. Therefore, as shown in FIG. 7, the height of the wall portion 14 of the retaining wall 12 is substantially the same as the road surface of the road 1 in the wife portion connected to the road 1, and in the wife portion connected to the bridge portion on the opposite side The height of the wall portion 14 of the retaining wall 12 is substantially the same as the road surface of the bridge portion. Moreover, the space | interval of the base part 13 of one side and the other base part 13 shall be 1 m. In addition, as shown in FIG. 8, the wall part 14 of the retaining wall 12 may be thickened and the cavity 17 may be formed inside the wall part 14.

次に、擁壁１２の橋梁部側妻部に妻壁を設け、擁壁１２の上端に高欄１６を沿道側縁部に沿って設置する。   Next, a gable wall is provided on the bridge-side side gable portion of the retaining wall 12, and a rail 16 is installed along the roadside edge at the upper end of the retaining wall 12.

次に、２列の擁壁１２の間にジャッキ１８をセッティングする。具体的には、掘削溝の中において２列の擁壁１２の土台部１３の間にジャッキ１８をセッティングする。次に、覆工板８を撤去する。次に、図９に示すように、ジャッキ１８を伸長させ、２列の擁壁１２の間隔を広げる。具体的には、両方の土台部１３を合わせて２．３ｍスライドさせ、壁部１４の外側の縁の間隔を８．５ｍに広げる。間隔を広げる量が大きい場合には、ジャッキ１８の盛替えを行う。基礎スラブ１０と擁壁１２との間に滑りシート１１が設けられているため、擁壁１２を軽い荷重で滑らせることができる。   Next, the jack 18 is set between the two rows of retaining walls 12. Specifically, the jack 18 is set between the base portions 13 of the two rows of retaining walls 12 in the excavation groove. Next, the lining plate 8 is removed. Next, as shown in FIG. 9, the jack 18 is extended to widen the interval between the two retaining walls 12. Specifically, both base portions 13 are combined and slid by 2.3 m, and the interval between the outer edges of the wall portion 14 is increased to 8.5 m. When the amount to increase the interval is large, the jack 18 is replaced. Since the sliding sheet 11 is provided between the foundation slab 10 and the retaining wall 12, the retaining wall 12 can be slid with a light load.

次に、図１０に示すように、２列の擁壁１２の受部１５の間にＲＣ床版１９を架け渡すように複数のＲＣ床版１９を受部１５に載置していき、ＲＣ床版１９を擁壁１２に接合する。次に、ジャッキ１８を撤去し、両方の土台部１３の間に鉄筋コンクリート製のベース２３を打設して、土台部１３の間隔を固定する。次に、ＲＣ床版１９の上に路盤２０を施工し、路盤２０の両端に排水舗装用の有孔管２１を敷設し、路盤２０の上に舗装２２を施工し、舗装２２に線引きを施工する。   Next, as shown in FIG. 10, a plurality of RC floor slabs 19 are placed on the receiving parts 15 so as to bridge the RC floor slabs 19 between the receiving parts 15 of the two rows of retaining walls 12. The floor slab 19 is joined to the retaining wall 12. Next, the jack 18 is removed, and a base 23 made of reinforced concrete is placed between both the base portions 13 to fix the interval between the base portions 13. Next, the roadbed 20 is constructed on the RC floor slab 19, the perforated pipe 21 for drainage pavement is laid on both ends of the roadbed 20, the pavement 22 is constructed on the roadbed 20, and the pavement 22 is drawn. To do.

このように構築されたアプローチにおいては、ＲＣ床版１９の下に中空２４が形成され、橋梁側妻部にその中空２４の開口が形成されるが、中空２４を土砂、コンクリート、軽量な材料等の充填材で充填しても良いし、橋梁側妻部の開口を化粧壁で閉塞しても良い。   In the approach constructed in this way, a hollow 24 is formed under the RC floor slab 19 and an opening of the hollow 24 is formed in the bridge side end portion. The hollow 24 is made of earth, sand, concrete, lightweight material, etc. It may be filled with a filler, or the opening on the bridge side end may be closed with a decorative wall.

以上のように本実施形態によれば、図３〜図５に示すように、工事開始時から２列の擁壁１２が完成するまでの間、覆工板８が設置されているため、覆工板８の上を車線として確保することができ、アプローチの工事開始時から完了時まで常に車線規制を行わなくとも済む。   As described above, according to the present embodiment, as shown in FIGS. 3 to 5, the lining plate 8 is installed from the start of construction until the two rows of retaining walls 12 are completed. The top of the work board 8 can be secured as a lane, and it is not always necessary to perform lane regulation from the start to the completion of approach construction.

また、図９〜図１０に示すように、覆工板８を撤去してから２列の擁壁１２の間隔を広げ、２列の擁壁１２の間に床版１９等を設置してアプローチの路面を構築すれば、アプローチの上を車道として解放することができる。このように、片側の車線が１車線となるとは、覆工板８を撤去してから床版１９等を設置するまでの間だけで済み、車線規制を長時間必要としない。従って、アプローチ構築工事を実施することで生じる交通渋滞が少なく、社会的・経済的な損失を低減することができる。   Further, as shown in FIGS. 9 to 10, after removing the lining plate 8, the interval between the two rows of retaining walls 12 is widened, and a floor slab 19 or the like is installed between the two rows of retaining walls 12. If the road surface is constructed, the approach can be released as a roadway. Thus, the lane on one side becomes a single lane only after the lining plate 8 is removed until the floor slab 19 is installed, and lane regulation is not required for a long time. Therefore, there is little traffic congestion caused by implementing the approach construction work, and social and economic losses can be reduced.

なお、上記実施形態では、滑りシート１１を基礎スラブ１０の上に敷設することによって擁壁１２を滑らせやすくしているが、他の滑り機構を基礎スラブ１０の上に設け、その滑り機構の上に擁壁１２を立設しても良い。例えば、滑り機構としての複数の滑り球を基礎スラブ１０の上に並べて、その上に擁壁１２を立設しても良いし、滑り機構として丸太などの円柱状部材を基礎スラブ１０の上に並べて、その上に擁壁１２を立設しても良い。このような各種の滑り機構によって、擁壁１２を軽い荷重で滑らせることができる。つまり、ジャッキ１８で擁壁１２の間隔を広げると、滑り球又は円柱状部材が転がって、擁壁１２を軽荷重で滑らすことができる。   In the above embodiment, the retaining wall 12 is easily slid by laying the sliding sheet 11 on the foundation slab 10, but another sliding mechanism is provided on the foundation slab 10, and the sliding mechanism The retaining wall 12 may be erected on the top. For example, a plurality of sliding balls as a sliding mechanism may be arranged on the foundation slab 10 and the retaining wall 12 may be erected thereon, or a columnar member such as a log may be placed on the foundation slab 10 as the sliding mechanism. The retaining walls 12 may be erected side by side. With such various sliding mechanisms, the retaining wall 12 can be slid with a light load. That is, when the interval between the retaining walls 12 is widened by the jack 18, the sliding ball or the cylindrical member rolls, and the retaining wall 12 can be slid with a light load.
