[0029] in, Figure 1 The reference direction coordinate system of the embodiment of the present application is given below. Figure 1 The embodiments of the present application are described with reference to the directions shown.

[0030] Thin-wall retaining walls are common in engineering projects. These are reinforced concrete structures and come in two main types: cantilever and buttress. A cantilever retaining wall consists of a vertical wall and a base plate, with three cantilevers: the vertical wall, toe plate, and heel plate. When the wall is tall, ribs (i.e., buttresses) can be installed at regular intervals along the length of the wall to connect the vertical wall plate and heel plate, creating a buttress retaining wall.

[0031] Reinforced concrete retaining walls can be prefabricated and transported to the site for installation. However, for retaining walls that are too large, factory prefabrication is not feasible due to the size requirements for road transport, and they must be cast in place. This cast-in-place method requires the construction of scaffolding and other working platforms, which is not conducive to improving construction efficiency and carries certain risks.

[0032] An embodiment of the present application provides a retaining wall structure, characterized in that it includes a wall 100, a first connecting component 110, a base 200 and a second connecting component 220, one end of the first connecting component 110 is pre-buried in the bottom of the wall 100, and the other end of the first connecting component 110 is fixedly connected to a rotating shaft 120, and the axial direction of the rotating shaft 120 is arranged along the length direction of the wall 100; a support portion 210 is provided on the base 200, and the support portion 210 is arranged along the length direction of the wall 100; the second connecting component 200 is arranged on the rear side of the support portion 210, and a card slot 221 cooperating with the rotating shaft 120 is provided on the second connecting component 200.

[0033] The retaining wall structure is provided with a first connecting component 110 at the bottom of the wall 100, and a second connecting component 200 is provided on the rear side of the support portion 210 on the base 200. The first connecting component 110 is rotatably connected by a rotating shaft 120 and a second connecting component 220 with a card slot 221 matched therewith, so as to realize the rotation connection between the wall and the base 200. During construction, the wall 100 and the base 200 are prefabricated on site at the construction site and then hoisted and assembled to complete the production and installation of the entire retaining wall structure, that is, the retaining wall structure is decomposed into several components, which are laid flat on the ground for prefabrication. After the production is completed, the rotating shaft 120 is inserted into the card slot 221, and the wall is hoisted by a hoisting device until it is The wall 100 stands upright on the base 200. When the wall 100 is in the upright state, the support part 210 supports the bottom of the wall 100, and the structure is stable, thereby realizing the assembly of the retaining wall structure. The use of this retaining wall structure for the construction of the retaining wall can eliminate the need for scaffolding, operating platforms and other auxiliary measures for high-altitude operations, thereby saving costs. The wall 100 and the base 200 can be prefabricated, reducing the use of casting formwork, facilitating construction, and reducing construction costs. During the construction of the retaining wall structure, only the wall 100 needs to be hoisted, and the wall 100 only needs to be flipped over with the rotating shaft 120 as the fulcrum. The lifting weight requirement for the lifting machinery when hoisting the wall is low, and construction is convenient.

[0034] In some embodiments, a slot 221 is provided at the top of the first connecting part 110 to form a first opening for inserting the rotating shaft 120, so that the rotating shaft 120 can be smoothly inserted into the bottom of the slot 221. The rear side of the support part 210 is provided with a second opening 222 to provide a rotation space for the first connecting part 110, so as to avoid the first connecting part 110 interfering with the rotation of the first connecting part 110. Specifically, the rotating shaft 120 is a cylindrical protrusion provided on the left and right sides of the first connecting part 110, and the rotating shaft 120 is stuck in the slot 221, so that the first connecting part 110 and the second connecting part 220 can rotate relative to each other.

[0035] In some embodiments, the base 200 includes a wall heel portion 230 located in front of the support portion 210 and a wall toe portion 240 located behind the wall 100. The wall heel portion 230 and the wall toe portion 240 are an integral structure to form the base 200, and the base 200 is rectangular as a whole.

[0036] In some embodiments, a rib 300 is provided between the wall 100 and the base 200. The rib 300 is located above the wall heel 230. The rib 300 is arranged along the width direction of the wall 100 to form a buttress retaining wall. The rib can increase the anti-slip and anti-overturning capabilities of the retaining wall, making the retaining wall more stable. The rib can provide additional support and resist soil pressure, reducing the risk of movement and deformation of the wall 100; the rib can also share the vertical and horizontal loads on the retaining wall structure and transfer them to the base 200, which helps to evenly distribute the load. The ribs 300 can distribute the load, reduce the burden on the retaining wall structure itself, and improve the bearing capacity of the entire structure; when the retaining wall structure is affected by external pressure or temperature changes, cracks may occur, and the ribs 300 can limit the expansion of the cracks to prevent the cracks from being too large and affecting the strength and stability of the wall; the ribs can improve the seismic resistance of the structure, help absorb and disperse earthquake energy, and reduce the risk of damage and collapse of the wall. It can be understood that in this application, the ribs 300 are prefabricated on-site at the construction site like the wall 100 and the base 200.

[0037] In some embodiments, the wall 100 is provided with a first embedded steel bar 130 on both sides along its length direction. The first embedded steel bar 130 runs through the wall 100. There are multiple walls 100, and adjacent walls 100 are tied together by the first embedded steel bars 130. It can be understood that the base 200 is also provided with multiple ones. The embedded steel bars can provide a firm connection, increase the integrity and stability between the walls; and the tensile strength of the steel bars can effectively resist seismic forces and enhance the seismic performance of the wall during earthquakes; the embedded steel bars can make the load between the walls evenly transferred, avoiding local concentrated force; the connection between the embedded steel bars can reduce the probability of problems such as wall cracking and deformation, and improve the safety of the retaining wall structure; the method of tying the embedded steel bars reduces the workload of connecting between the walls 100 and improves construction efficiency; and compared with other connection methods, the tying of the embedded steel bars is relatively low in cost and has reliable performance.

[0038] In some embodiments, a second embedded steel bar 310 is provided on the rear side of the rib 300. The second embedded steel bar 310 is tied together with the first embedded steel bar 130 to provide a stable connection between the rib 300 and the wall 100. The construction is simple, and the material cost and labor cost are low. As long as the tying is firm, the connection between the steel bars can provide sufficient strength and stability, which is convenient for the subsequent pouring between the rib 300 and the wall 100. The steel bar connection after tying is easy to check, and any problems found can be dealt with in a timely manner.

[0039] In some embodiments, a positioning portion 231 is provided at the top of the wall heel 230, and a positioning hole is provided at the bottom of the rib 300 to cooperate with the positioning portion 231. A pre-buried pipe is provided at the bottom of the rib 300, and a positioning hole is formed in the pre-buried pipe. The positioning portion 231 is a third embedded steel bar embedded in the wall heel 230. The inner diameter of the positioning hole is larger than the diameter of the third embedded steel bar. The connection between the positioning hole and the third embedded steel bar can improve the accuracy of the connection, make the connection between the rib 300 and the base 200 more stable, and reduce the possibility of displacement and deformation. Such a setting can also speed up the construction speed of the retaining wall structure and reduce the time for on-site adjustment. The third embedded steel bar protrudes from the base 200, and the connection part is clearly visible, which is convenient for inspection and maintenance. The setting of the third embedded steel bar makes the rib 300 tightly connected to the base 200 to form a whole, jointly bear the load, improve the safety of the structure, maintain the reliability of the retaining wall structure for a long time, and reduce the cost of maintenance and replacement.

[0040] In some embodiments, a slurry inlet hole 320 is provided on the rib 300, and the slurry inlet hole 320 is connected to the positioning hole. The slurry inlet hole 320 is located at the bottom of the rib 300. The rib 300 and the base 200 are firmly connected by grouting into the slurry inlet hole, so that the rib 300 and the base 200 become a whole and can jointly withstand external forces, which helps to improve the overall stability of the retaining wall structure, reduce the risk of tilting and shaking, and enable the load to be more evenly distributed on the base 200 and the wall 100, avoiding local concentrated force on the retaining wall structure. The grouting method can also fill the tiny gap between the base 200 and the wall 100 to prevent moisture penetration and air entry, improve the bonding strength between the base and the wall, ensure a firm and reliable connection, and the slurry pouring is relatively simple, the construction process is relatively convenient, the cost is low, and it has good economic benefits.

[0041] In some embodiments, a slurry outlet hole 330 is provided on the rib 300, and the slurry outlet hole 330 is connected to the slurry inlet hole 320. The slurry outlet hole 330 is located above the slurry inlet hole 320. When the grouting amount is sufficient, the excess slurry emerges through the slurry outlet hole, which proves that the grouting is completed.

[0042] In some embodiments, multiple positioning portions 231 and positioning holes are provided along the width direction of the wall 100, and positioning portions 231 are provided on both sides of the base 200 along the length direction of the wall 100. In other words, the position spacing of the third embedded steel bars and the positioning holes corresponds one to one.

[0043] In some embodiments, a hook 140 is provided on the top of the wall 100 to facilitate lifting the wall 100 .

[0044] It can be understood that after the wall 100 is flipped 90 degrees, the wall 100 stands upright on the base 200, and then it is necessary to cast between adjacent walls 100 so that the wall 100, the base 200 and the ribs 300 form a whole, completing the construction of the retaining wall structure, saving the time of moving the wall, speeding up the construction progress, avoiding damage to the wall 100 during the flipping process, and ensuring the safety of the wall 100 lifting process.
