[0002] In water conservancy projects, excavation is a crucial step, involving the excavation and modification of rivers, lakes, and reservoirs. To ensure safety during the excavation process, slope protection is essential, making the design and application of support devices particularly important. Currently, most water conservancy slope protection devices utilize monolithically cast concrete retaining walls. To enhance the stability of these retaining walls during use, a top-support structure is typically added to the bottom.

[0003] To facilitate installation and construction, these support devices are generally prefabricated. However, existing prefabricated concrete retaining walls are quite heavy, making transportation time-consuming and labor-intensive, increasing construction costs and timelines. Therefore, this proposal suggests a slope excavation support device for water conservancy projects to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a slope excavation and support device for water conservancy projects to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slope excavation support device for water conservancy projects, comprising a retaining wall, wherein the top of the retaining wall is provided with multiple sand-filling grooves, and further comprising:

[0009] Preferably, the top support structure includes:

[0010] A support block, which is fixedly connected to the front of the bottom of the retaining wall, has a triangular vertical cross-section.

[0011] A retaining block is fixedly connected to the back of the bottom of the retaining wall, and the vertical cross-section of the retaining block is trapezoidal.

[0012] Preferably, the retaining wall has a sand discharge hole at its bottom and on the side near the back, and the sealing mechanism is disposed in the sand discharge hole.

[0013] Preferably, the sealing mechanism includes a sealing block, which is inserted into the sand discharge hole, and a pull ring is provided at the middle of the sealing block and at the end away from the sand discharge hole.

[0014] Preferably, one side of the retaining wall has multiple docking holes in the vertical direction, and the other side of the retaining wall has multiple docking columns fixedly connected in the vertical direction.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a slope excavation support device for water conservancy projects, as shown in Figures 1-4, including a retaining wall 1. The top of the retaining wall 1 is provided with multiple sand filling grooves 104. One side of the retaining wall 1 is provided with multiple docking holes 105 in the vertical direction. The other side of the retaining wall 1 is fixedly connected with multiple docking columns 106 in the vertical direction. The docking holes 105 and docking columns 106 are used for splicing multiple retaining walls 1 along the side.

[0027] It should be noted that by opening the sand filling trough 104, the volume of the retaining wall 1 can be reduced. In this scheme, the sand filling trough 104 is opened from top to bottom along the top of the retaining wall 1 and is a rectangular trough structure.

[0028] The dimensions of the connecting hole 105 and the connecting column 106 are adapted to each other. This allows for the stable assembly of multiple retaining walls 1 when they need to be horizontally joined, through the interlocking of the connecting hole 105 and the connecting column 106. A sealing mechanism 4, with multiple sets arranged at the bottom of the retaining wall 1, is used for sealing the sand discharge from multiple sand-filling troughs 104.

[0029] Specifically, a sand discharge hole 107 is provided at the bottom of the retaining wall 1, on the side closest to the back. The sand discharge hole 107 is interconnected with the bottom of the sand filling trough 104, and the sand discharge hole 107 is opened at an angle, with the bottom being the lowest point. The sealing mechanism 4 is disposed inside the sand discharge hole 107. Furthermore, the sealing mechanism 4 includes a sealing block 401, which is inserted into the sand discharge hole 107. A pull ring 402 is provided at the middle of the sealing block 401, at the end furthest from the sand discharge hole 107.

[0030] It should be noted that the structure of the sealing block 401 is compatible with the sand discharge hole 107. In order to ensure the stability of the installation of the sealing block 401 and the sand discharge hole 107, the two can be combined by threaded connection. The pull ring 402 is provided to facilitate the removal of the sealing block 401 from the sand discharge hole 107.

[0031] The top support structure is installed at the bottom of the retaining wall 1 and is used to support the bottom of the retaining wall 1.

[0032] Specifically, the supporting structure includes:

[0033] Support block 2 is fixedly connected to the front of the bottom of retaining wall 1, and the vertical cross section of support block 2 is triangular.

[0034] The retaining block 3 is fixedly connected to the back of the bottom of the retaining wall 1, and the vertical cross section of the retaining block 3 is trapezoidal.

[0035] It should be noted that by setting the support block 2 and the abutment block 3 at the bottom of the retaining wall 1, the erection of the retaining wall 1 is made more stable, thereby ensuring that the retaining wall 1 has the ability to resist impact.

[0036] The retaining wall 1 has multiple openings 101 in the middle, and a sealing mechanism can be detachably installed at each of the multiple openings 101. The sealing mechanism is used to block the openings 101. The front of the retaining wall 1 and located at the openings 101 have multiple mounting slots 102, which are used to install the sealing mechanism.

[0037] Specifically, the sealing mechanism includes a sealing plate 5, which is sleeved in the mounting groove 102, and the sealing plate 5 has multiple leakage holes 501 in the middle.

[0038] It should be noted that by opening the opening 101, the initial volume of the retaining wall 1 is further reduced, and the opening 101 avoids the sand filling groove 104. When it is necessary to seal the corresponding area, the opening 101 at the corresponding position is sealed by the nested installation of the sealing plate 5.

[0039] Furthermore, each end corner of the mounting groove 102 is fixedly connected with a threaded post 103, and multiple threaded posts 103 are respectively inserted and connected to the end corner of the sealing plate 5. Each threaded post 103 has a fastening nut 6 threadedly sleeved on its outer wall.

[0040] It should be noted that the threaded post 103 is installed in the mounting groove 102. Therefore, when installing the sealing plate 5, a mounting hole needs to be opened at the end corner of the sealing plate 5. The sealing plate 5 and the threaded post 103 are connected by the mounting hole. Then, the fastening nut 6 is tightened. The installation of the sealing plate 5 in the mounting groove 102 is achieved by the cooperation between the fastening nut 6 and the threaded post 103.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
