Description

[Detailed description of the invention] [Field of industrial application] The invention can be easily constructed by combining reinforced concrete members, and the constructed retaining wall is not only flexible, but also flexible. This invention relates to a well-girder retaining wall body made of reinforced concrete that can be made into a high retaining wall and is also durable.

[Conventional technology]

In general, even if an earth retaining wall is strong in itself, if it is not flexible against uneven ground subsidence or flow, there is a risk of destruction due to localized excessive force. If measures are not taken to drain spring water, surface water, etc. flowing from the mountainside, this water may accumulate behind the retaining wall and cause it to collapse, but conventional retaining walls are not necessarily perfect. However, the masonry work was often complicated and time-consuming.

[Problem that the invention attempts to solve]

First, the required number of rods G11, G12, G13...
... are installed on the ground at appropriate regular intervals with the locking flange 12 in front and the pedestals 15 and 16 upward, and the vertical reinforcing bars T are inserted into the through holes 17 and 17' for vertical reinforcing bars, and the lower part is Fix by means.

Next, the hanging part 56' between the small wing part 54' and the wing part 52' of the rod C11 is connected to the hanging part 1 of the front part of the rod G11.
3, and the left end of the rod C11 is similarly placed on the hanging portion 13 at the front of the rod G12. Rod A11
The right end of the curved through hole 27 on the end face of the rod C11
is installed on the hanging part 13 of the rod G12 so as to face the curved through hole 55 on the left end face of the rod with a ring 71 made of synthetic resin or rubber interposed therebetween. Connect the hanging part 28' to the rod G13.
The left end of the rod A11 is mounted on the front hanging part 13 of the rod G14, and
The connecting curved bolt 72 is inserted through the curved through-holes 55, 27 and the ring 71, and the end portion is screwed with a nut 73.

Next, similarly, the right end of the rod A12 is placed on the hanging part 13 of the rod G14, with the curved through hole 27 on the end face facing the curved through hole 26 on the left end face of the rod A11 via the ring 71. The hook 28' between the wings 22' and 23' at the intermediate position is connected to the front hook 13 of the rod G14, and the left end of the rod A12 is connected to the front hook of the rod G15 (not shown). 13 respectively, and connect the curved connecting bolts 72 through the curved through holes 2.
6, 27 and ring 71, and screw the ends with nuts 73.

Hereafter, the masonry work is continued in the same manner as above on the rod A, and when the masonry of the front rods C and A is completed, the rod C' is laid on the left end side, and the masonry work is continued in the same manner as above. Complete the masonry. The rear part of the first stage is the same as the front part when viewed from the back, that is, the rod C' is placed opposite the rod C, and the rod A is placed opposite the rod A, with the wing sides facing each other. masonry

Next, the rods F11, F12, F13... are erected through the vertical reinforcing bars T through the through holes 7, 7', and the pedestals 3', 4' are attached to the rods G11, G1.
2, G13... placed on the pedestals 15, 16.
Next, the hooking portion 37′ between the small wing portion 39′ and the wing portion 33′ of the rod B21 and the hooking portion 36′ between the wing portions 32′ and 33′ are attached to the front hooks of the rods F21 and F22, respectively. The left end portion of the rod B21 is similarly placed on the front hanging portion 5 of the rod F23. next,
The right end of the rod A21 is connected to the curved through hole 27 on the end surface of the rod B21, and the ring 71 is inserted into the curved through hole 38 on the left end surface of the rod B21.
mounted on the hanging part 5 of the rod F23, facing each other through the
The hanging part 28' between the middle wings 22' and 23' of the rod A21 is connected to the front hanging part 5 of the rod F24 (not shown), and the left end of the rod A21 is connected to the rod F25.
The connecting curved bolts 72 are inserted through the curved through holes 38, 27 and the ring 71, and the ends are screwed with nuts 73.

In this way, rod A22... is changed to rod A21.
After completing the masonry of the front part of the second stage by building the rod B' on the leftmost side, the rear part of the second stage is built in the same way as the rear part of the first stage. masonry

Hereafter, the appropriate number of stages is laid using the same method as the second stage, and when that is completed, the rod Gn
1, Gn2, Gn3... vertical reinforcing bar penetration holes 17,
A vertical reinforcing bar T is erected through the pedestal 15,1 at 17'.
6 on the pedestals 3 and 4 of the rods F(n-1)1, F(n-1)2..., and tighten the upper ends of the vertical reinforcing bars with nuts, the rods A located on the front and rear sides ，
B, B', C, and C' are locked to the edges of rods G and F, and rods A, B, B', C, and C' are connected laterally on the front and rear sides. When connected by the bending bolts 72, a parallel cross-shaped frame with four sides is formed.

In the above example, when building the rods, the cross-shaped frame was formed while installing the vertical reinforcing bars T and the connecting curved bolts 72, but these installations should be performed after the frame is formed. is possible.

The hollow space D of the cross-shaped frame constructed as described above is filled with chestnut stone E to form a retaining wall, but the rods A, B, B', C, and C' are Since each rod has a wing section, the gap between the rods is small, and Kuriishi E
Even if it is small, it can be filled without escaping.

[Effect of idea]

The present invention is as described above, and includes rods F, G,
A, B, B', C, and C' are stacked, and in the height direction, the rods G and F are placed on the pedestal of the lower rod, and are connected by vertical reinforcing bars placed upright in the front and back. The rods G and F are placed on the pedestal of the lower rod, and the rods A, B, B', C, and C' are connected by pins using curved connecting bolts. A gap is formed between the rod-like base and the rods F and G are not directly mounted on the rods A, B, B', C, and C', so even when the ground changes or flows, the rods G and F Due to the gaps between the rods A, B, B', C, and C', and the pin connection using the curved connecting bolts, the rods act like a futon and are protected against ground movement. It can be easily tracked without causing major damage, and since the inside of the frame is filled with chestnut stone, even if spring water from the mountainside on the back or surface water flows into the frame, there will be no gaps. Since there are many retaining walls, drainage is also good, and overall it is easy to construct, and compared to conventional retaining walls, it has great economic effects such as shortening the construction period.
