[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a novel pile-plate type retaining wall which can prevent the unstable settlement of the retaining plate.

[0026] The utility model provides Figure 1-4 A new type of pile-plate retaining wall for preventing unstable settlement of a retaining plate shown in the figure comprises a plurality of pile bodies 1 and a special-shaped ground beam 2 fixedly arranged between two adjacent pile bodies 1, wherein the special-shaped ground beam 2 is arranged in a T shape, and a retaining plate 3 is placed on the top of the special-shaped ground beam 2;

[0027] A plurality of symmetrically arranged positioning rods 4 are fixedly provided on the top of the special-shaped ground beam 2, and the retaining plate 3 is arranged between the plurality of positioning rods 4. A pressure ring 5 is rotatably sleeved on the outer upper end of the positioning rod 4, and an operating groove 6 is opened on the outer wall of the pressure ring 5. The two ends of the pressure ring 5 are convex.

[0028] When constructing a retaining wall, the position of the pile body 1 is first fixed, and then the special-shaped ground beam 2 is fixed between two adjacent pile bodies 1. Therefore, during the installation of the retaining plate 3, the retaining plate 3 can be stably and rigidly supported by the setting of the special-shaped ground beam 2, and uneven settlement of the bottom of the retaining plate 1 during installation can be avoided as much as possible. Before installing the bottom retaining plate 3, the retaining plate 3 can be placed between multiple positioning rods 4 to install and position the retaining plate 3, thereby improving the installation convenience of the retaining plate 3.

[0029] In order to stably squeeze and position the retaining plate 3 when installing the bottom retaining plate 3, and further improve the installation convenience of the retaining plate 3, as shown in FIG. Figure 1 and Figure 3-4 As shown, a positioning and squeezing mechanism for limiting the position of the pressure ring 5 is provided in the operating groove 6, and the positioning and squeezing mechanism includes an insert rod 8. A plurality of positioning grooves 9 are symmetrically arranged on the outer side of the positioning rod 4. The insert rod 8 is slidably arranged in the operating groove 6 and inserted into the positioning groove 9. A spring 10 is sleeved on the rod wall of the insert rod 8. Both ends of the spring 10 are respectively fixedly connected to the insert rod 8 and the operating groove 6. A connecting block 11 is fixedly provided at the end of the insert rod 8. A cross bar 12 is rotatably penetrated through the inner wall of the connecting block 11, and pull rings 13 are fixedly provided at both ends of the cross bar 12.

[0030] When installing the bottom retaining plate 3, the retaining plate 3 is first placed between the multiple positioning rods 4, and then the pull rings 13 inside the operating grooves 6 outside the multiple pressure rings 5 ​​are pulled in turn, so that the pull ring 13 stretches the insertion rod 8, so that the insertion rod 8 stretches the spring 10 and is pulled out of the positioning groove 9, and then the pressure ring 5 is rotated so that the protruding ends on both sides of the pressure ring 5 contact the retaining plate 3, and then the pull ring 13 is released. Under the elastic force recovery of the spring 10, the insertion rod 8 is inserted into the positioning groove 9 to fix the positions of the insertion rod 8 and the pressure ring 5. Therefore, after the multiple pressure rings 5 ​​are adjusted, the retaining plate 3 can be stably squeezed between the multiple pressure rings 5 ​​and the positioning rods 4, thereby improving the convenience of connection between the retaining plate 3 and the pile body 1.

[0031] In order to stably support the rotation of the pressure ring 5, Figure 1 and Figure 4 As shown, two symmetrically arranged annular baffles 7 are fixedly provided at the upper end of the rod wall of the positioning rod 4 , and the pressure ring 5 is arranged between the two annular baffles 7 .

[0032] When the pressure ring 5 rotates, the two annular baffles 7 can support and limit the rotation of the pressure ring 5 so that the pressure ring 5 can be in stable contact with the retaining plate 3.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
