摘要： PURPOSE:To effectively eliminate waves is keeping the permeable function of water alive by a method wherein multi pieces of horizontally disposed piles are disposed and wave eliminating materials are fitted between the disposed piles with sliding position. CONSTITUTION:For the first row of the horizontally disposed piles 1a 1b... a wave eliminating material 2 is placed between the pile 1b and the pile 1c and between piles 1d and 1e, respectively. For the second row of the horizontally disposed piles 1a, 1b..., the material 2 is placed between piles 1a and 1b, between piles 1c, and 1d, and between the piles 1e and 1f. For the third row of the horizontal disposed piles 1a, 1b..., the material 2 is placed between the piles 1b, and 1c and between the piles 1d and 1e. These materials are placed in zigzag in the proceeding direction of waves. Waves sequentially hit the materials placed in zigzag to disappear, however, water penetrates through the space of piles 3 where the material 2 is not placed. As a result, obstruction does not occur for the exchange of water and spending can be expected in the same degree of a wave eliminating wall in which waves are completely intercepted.

摘要： PURPOSE:To join a follow-up pile to a preceding pile without using field welding, and to make the inner and outer diameters of the joined part equal to those of a main pipe part. CONSTITUTION:The rear end of a preceding steel pipe pile 10 and the front end of a follow-up steel pipe pile 11 are beforehand attached thereto with auxiliary short pipes 12, 13 having diameters smaller than the outer diameters of the steel pipe piles, and a coupler 14 adapted to be fitted on both short pipes is fitted on the auxiliary short pipe 12 on the preceding steel pipe pile 10 side. Then, the auxiliary short pipe 13 on the follow-up steel pipe pile 11 side, is made into press-contact with the rear end of the auxiliary short pipe 12 on the preceding steel pipe pile 10 side. A filling and solidifying material is filled in the coupler 14 and in a space between both short pipes 12, 13 from a small hole 14a in the coupler 14.

摘要： PURPOSE:To make its form easier to manufacture and combine it with a rectilinearly shaped steel sheet-pile equipped with forked joints so as to construct it at a low cost, by integrally forming each wing piece for engagement on each end of the web of a steel sheet-pile in its longitudinal direction, the cross section of which latter pile is in a U-shape, so as to form them together in a pi-shape. CONSTITUTION:Each wing piece 1d for engagement is installed on each end of the web 1a of the main body of each steel sheet-pile in its longitudinal direction, the pile constituted of its web 1a, its flanges 1b and its joints 1c, and the cross section of which is in a U-shape, so that they are formed together in a pi-shaped steel sheet pile 1. And each pi-shaped steel sheet-pile 1 is placed with the surface of its web 1a facing toward a water area, then each U-shaped steel sheet-pile 2 is placed with the surface of its web 2a facing toward a bank while each of joints 2c and each of the joints 1c are engaged together. After they have successively been placed in sequence likewise, each rectilinearly shaped steel sheet pile 3 provided with each forked joint paired (a) on each end is placed while each wing piece 1d is fittingly inserted into each forked joint 3a.
