Description

  The present invention relates to a technique for building shade concrete using a shade block on a sheet pile wall.

  A large number of sheet piles are driven in parallel on the shores of waterways, rivers, lakes and harbors, and a sheet pile wall for revetment is constructed. In the sheet pile wall, the vertical ridges and the vertical grooves are alternately arranged on the front surface on the water side and the rear surface on the land side, and are uneven in the left-right direction. A large number of shade blocks are placed on top of the sheet pile wall. The shade block on the sheet pile wall connects the neighbors. Concrete is packed between the top of the sheet pile wall and the shade block covering it. Steel sheet pile wall, concrete shade block and filled concrete are integrated. Shade concrete covering the upper part of the sheet pile wall is constructed.

The shade block used on the shore where the fluctuation of the water level is small is exemplified in Patent Document 1.
The shade block includes a front plate, a rear plate, and a top member. The top member penetrates the work hole. At the time of construction, the shade block is put on the sheet pile wall. The top member is placed on the sheet pile wall, the front plate is disposed on the front side and the water side of the sheet pile wall, and the rear plate is disposed on the rear side and the land side of the sheet pile wall and is placed on the ground surface. The lower end of the gap between the front plate of the shade block and the sheet pile wall is open. A plurality of formwork plates are fixed to the lower side of the front plate of the shade block with a receiving metal fitting or a vise, respectively. As for a formwork board, an upper surface contacts the lower end surface of a front board, and a rear end surface contacts the front surface of a sheet pile wall. The rear end surface of the formwork plate is uneven so as to fit into the unevenness on the front face of the sheet pile wall. In the gap between the front plate of the shade block and the sheet pile wall, the lower end opening is closed by a plurality of formwork plates. A recess is formed between the front plate of the shade block and the sheet pile wall. The recess is filled with concrete through the work hole of the top member. After the concrete has hardened, remove the metal fittings and vise from each formwork plate. Each formwork plate is peeled off from the filled concrete.

  The other shade block is provided with a bottom plate projecting rearward from the lower end of the front plate of the shade block, and a packing is fixed to the rear end surface of the bottom plate. The back end face with packing of the bottom plate is made uneven so as to fit into the unevenness on the front face of the sheet pile wall. At the time of construction, when the shade block is put on the sheet pile wall, the packing at the rear end of the bottom plate hits the front face of the sheet pile wall. In the gap between the front plate of the shade block and the sheet pile wall, the opening at the lower end is closed by the bottom plate with packing.

The shade block used on the shore where the fluctuation of the water level is large is exemplified in Patent Document 2.
The shade block is provided with a top member and a bottom plate protruding rearward at the upper and lower ends of the front plate. The top member penetrates the work hole. The bottom plate has a packing fixed to the rear end face. The back end face with packing of the bottom plate is made uneven so as to fit into the unevenness on the front face of the sheet pile wall. At the time of construction, the shade block is put on the sheet pile wall. The top member is placed on the sheet pile wall, the front plate is disposed on the front side of the sheet pile wall, and the packing at the rear end of the bottom plate is in contact with the front surface of the sheet pile wall. The shade block pulls the front plate toward the sheet pile wall and presses the packing at the rear end of the bottom plate against the front surface of the sheet pile wall. In the gap between the front plate of the shade block and the sheet pile wall, the opening at the lower end is closed by the bottom plate with packing. The gap between the front plate of the shade block and the sheet pile wall is filled with concrete through the work hole of the top member.

[Task]
In the sheet pile wall, the vertical ridge and the vertical groove are shifted in the front-rear direction and the left-right direction from the design position due to an error in the parallel position of the sheet piles. On the front surface of the sheet pile wall, unevenness in the left-right direction is uneven. Since the sheet pile wall for revetment has a large tolerance for the inclination of the sheet pile, the amount of deviation and unevenness of the unevenness in the left-right direction on the front surface increases.

  In the construction using the above-mentioned formwork plate and the shade block, the position where the formwork plate is attached to the shade block can be adjusted according to the position of the unevenness in the left-right direction on the front face of the sheet pile wall. A gap through which concrete leaks hardly occurs between the sheet pile wall and the formwork plate. However, it takes time to attach the mold plate to the receiving metal fitting or vise, to remove the metal fitting or vise, and to remove the mold plate from the filled concrete. Construction takes a lot of work.

  In the construction using the shade block with the above-mentioned bottom plate, the bottom plate is fixed to the shade block, and the position of the bottom plate cannot be adjusted according to the position of the unevenness in the left-right direction on the front face of the sheet pile wall. A gap through which concrete leaks easily occurs between the sheet pile wall and the bottom plate with packing.

  Eventually, a technique is desired that makes it difficult to generate a gap through which concrete leaks at the lower end of the gap between the sheet pile wall and the front plate of the shade block without much effort.

In addition, the bottom plate is movable, and the attachment position can be adjusted according to the position of the unevenness in the left-right direction on the front face of the sheet pile wall. At the time of construction, the shade block is put on the sheet pile wall. The front plate, the mounting member, and the movable bottom plate are disposed on the front side of the sheet pile wall. The movable bottom plate is moved in the front-rear direction and the left-right direction according to the position of the left-right unevenness on the front face of the sheet pile wall, the unevenness on the rear end face is fitted to the left-right unevenness on the front face of the sheet pile wall, and the rear end face is the front face of the sheet pile wall To touch.

Adjust. The rear end surface with the packing 23 is brought into contact with the front surface of the sheet pile wall 1. The unevenness of the rear end face with the packing 23 is closely fitted to the unevenness in the left-right direction on the front face of the sheet pile wall.

  After adjusting the mounting position of the movable bottom plate 21, each movable bottom plate 21 is fastened to the lower end of the front plate 12 via the mounting member 15 by tightening the bolt 27 with a rotary tool inserted from the work hole 16. The lower end of the gap between the front plate 12 and the sheet pile wall 1 of the shade block 11 is closed with a plurality of movable bottom plates 21 attached to the attachment member 15.

  After fixing the movable bottom plate 21, the space between the front plate 12, the rear plate 13 and the sheet pile wall 1 of the cap block 11 is filled with concrete 29 through the work hole 16, as shown in FIG. The concrete 29 hardens in a state where the upper portion of the sheet pile wall 1, the height adjuster 3 and the front / rear position adjuster 4, the movable bottom plate 21, the bolt 27 and the seat plate 26 are buried. On the top of the sheet pile wall 1, cap concrete is constructed.

[Second Example (see FIGS. 10 to 15)]
In the shade block of this example, the relative positions of the movable bottom plate and the sheet pile in the sheet pile wall in the first example are changed. Each movable bottom plate is arranged on the front side of one sheet pile in the sheet pile wall, and the unevenness on the rear end face is fitted to the left and right direction unevenness on the front face of one sheet pile located on the rear side. One movable bottom plate copes with the positional deviation of one sheet pile in the sheet pile wall.
