出のために水中ポンプ等の使用が一般には行われ
ている。(Conventional technology) Conventionally, retaining walls using steel sheet piles for underground construction of this type of building were simply connected one after another and driven into the ground. When excavation is carried out, groundwater leaks from the joints of the steel sheet piles and flows into the excavated area. Therefore, submersible pumps and the like are generally used to discharge the water.
また、海洋や河川の水中構造物の構築工事等に
おいては、海水や川水等の遮断を目的として鋼矢
板を二重に設置する等の点に問題があつた。 Furthermore, in the construction work of underwater structures in the ocean and rivers, problems have arisen in the installation of double steel sheet piles for the purpose of blocking seawater, river water, etc.

経済である等の点に問題がある。 For this reason, some contractors apply a sealant to the joints of steel sheet piles during construction. However, with this sealing method, the sealant is applied before driving the steel sheet piles, so the work is complicated, and it is uneconomical because it has to be applied to all the steel sheet piles. There is.

孔１２に挿通して押え材４に打込む。 Next, at the location where water leaks in the joint 2 of the steel sheet piles 1, 1, a water-swellable rubber material 3 is placed at the front corner of the joint 2 of the steel sheet piles 1, 1 on both sides, as shown in FIG.
The water-swellable rubber material 3 is pressed against the front corner using the presser material 4, and the front surface of the gutter 5 of the rear steel sheet pile 1 and the side surface of the front steel sheet pile 1 adjacent thereto. Hand it over to touch it. Therefore, at appropriate locations, the receivers 11 of the presser washers 9 on both sides of the extension fitting a were engaged with the front inner corners of the pressers 4 on both sides, and the presser washers 9 were applied to the pressers 4, 4. After that, the pegs 17 are inserted into the nail holes 12 of the presser washer 9 on both sides and driven into the presser member 4.

３，３を継目部２，２に圧接させる。 Then, use the wrench to connect the engaging part 7 of the turnbuckle 6 .
When the turnbuckle 6 is rotated in one direction, the extension fitting a is extended by the screw engagement of the bolts 15 1 and 15 2 with the internal threads 8 1 and 8 2 of the turnbuckle 6 in opposite left and right directions. The pressers 4, 4 are pushed outward by the presser washers 9 , 9 , and the water-swellable rubber materials 3, 3 are brought into pressure contact with the joint portions 2, 2.
従つて、鋼矢板１，１の継目部２の隙間を水膨
潤性ゴム材３により密封するから、地下水が鋼矢

行うことができる。(1) After driving steel sheet piles and excavating the building side, apply a water-swellable rubber material to the joints of the steel sheet piles on the excavated side, and press it with an extension fitting and holding material to remove the steel sheet piles. Since it prevents water from leaking from the joints, the construction is simple and can be carried out easily and accurately.
(2) 鋼矢板の継目箇所中で漏水する箇所だけに水
膨潤性ゴム材を当てて施工するから、その施工
箇所が少なくて資材および手数を節減して経済
的である。(2) Since the water-swellable rubber material is applied only to the joints of steel sheet piles where water leaks, the number of construction points is small, which saves on materials and labor, making it economical.
(3) 伸長金具により両側の押え材を介して両側の
水膨潤性ゴム材を同時に鋼矢板の継目部に押圧
するから、その操作が簡単で、着脱を迅速にな
し得て作業上便利である。(3) Since the water-swellable rubber material on both sides is simultaneously pressed against the seam of the steel sheet piles using the extension fittings via the holding members on both sides, the operation is easy and the attachment/detachment can be done quickly, making it convenient for work. .
(4) 水膨潤性ゴム材を使用するから、鋼矢板の継
