[0019] This utility model provides a drainage structure for a retaining wall in a hydraulic engineering project, including a retaining wall body 101 and a drainage component 102. The drainage component 102 includes an outer pipe 103, an inner pipe 104, a mesh cylinder 105, a threaded ring 106, a connecting member 107, and a sealing member 117. The mesh cylinder 105 includes a cylinder body 108 and a baffle 109. The connecting member 107 includes a compression spring 110, a locking member 111, and a driving component 112. The driving component 112 includes a tension spring 113, a driving seat 114, a connecting rod 115, and a pressure... Ring 116, the sealing component 117 includes an abutment plate 118, a mounting plate 119 and a sealing gasket 120. The inner tube 104 is installed through the connecting component 107, so that the inner tube 104 can be removed from the outer tube 103, thereby facilitating the removal of the mesh cylinder 105. At this time, it is convenient to clean and replace the mesh cylinder 105. It can be understood that the above solution can be used to facilitate the cleaning and replacement of the mesh cylinder 105, and can also be used to facilitate the installation and removal of the inner tube 104.

[0020] In this specific embodiment, the outer pipe 103 is fixedly connected to the retaining wall body 101 and located inside the retaining wall body 101; the inner pipe 104 is connected to the outer pipe 103 and located inside the outer pipe 103; the threaded ring 106 is fixedly connected to the inner pipe 104 and located inside the inner pipe 104; the mesh cylinder 105 is threadedly connected to the threaded ring 106 and sleeved on the threaded ring 106; the connecting member 107 is disposed on the outer pipe 103; multiple drainage components 102 are provided; the inner pipe 104 is detachably connected to the outer pipe 103 through the connecting member 107; and the mesh cylinder 105 is used to filter water.

[0021] In use, the mesh cylinder 105 is threadedly connected to the threaded ring 106, and then the inner tube 104 is inserted into the inner side of the outer tube 103. The inner tube 104 is fixedly installed on the outer tube 103 by the connecting member 107. The mesh cylinder 105 filters the water entering the drainage structure, blocking impurities such as mud, sand, and stones from entering and preventing blockage of the drainage pipe. When the mesh cylinder 105 becomes blocked, the locking of the inner tube 104 by the connecting member 107 is released. At this time, the inner tube 104 and the mesh cylinder 105 are removed from the outer tube 103, making it convenient to replace and clean the mesh cylinder 105. This facilitates the replacement and cleaning of the mesh cylinder 105 and avoids affecting the normal drainage of the retaining wall body 101.

[0022] The cylindrical body 108 is threadedly connected to the threaded ring 106 and is fitted onto the threaded ring 106; the baffle 109 is connected to the cylindrical body 108 and contacts the threaded ring 106, and is located inside the cylindrical body 108; the interior of the cylindrical body 108 is filled with sand 121; the mesh cylinder 105 and the baffle 109 have a mesh structure, allowing water to flow through while preventing the sand 121 from passing through; a cavity is formed inside the baffle 109 and the mesh cylinder 105, which is filled with sand 121. The sand 121 can intercept finer impurities, making the water entering the drainage structure clearer and effectively reducing the risk of the inner pipe 104 being blocked; when the mesh cylinder 105 is threadedly connected to the threaded ring 106, the sand 121 is confined inside the cavity by the baffle 109, preventing the sand 121 from entering the inner pipe 104.

[0023] Secondly, the locking member 111 is connected to the outer tube 103 and is disposed on the outer tube 103; the two ends of the compression spring 110 are respectively connected to the outer tube 103 and the locking member 111, and the compression spring 110 is located inside the outer tube 103; the driving component 112 is disposed on the outer tube 103.

[0024] Meanwhile, the drive seat 114 is slidably connected to the outer tube 103 and contacts the locking member 111; the connecting rod 115 is fixedly connected to the drive seat 114 and is located on one side of the drive seat 114; the pressure ring 116 is fixedly connected to the connecting rod 115 and is located at the end of the connecting rod 115 away from the drive seat 114; the two ends of the tension spring 113 are respectively connected to the drive seat 114 and the outer tube 103, and the tension spring 113 is sleeved on the connecting rod 115.

[0025] Multiple locking members 111 and driving seats 114 are provided. The locking members 111 and driving seats 114 have mutually cooperating inclined surfaces. The inner tube 104 has a locking groove that mates with the locking members 111. When the inner tube 104 is installed, it is inserted into the inner side of the outer tube 103. When the locking groove on the inner tube 104 moves to the locking member 111, the locking member 111 extends into the inner tube 111 under the action of the compression spring 110. The inner tube 104 is installed on the outer tube 103 by locking the groove on the inner tube 104. When the inner tube 104 needs to be disassembled, the pressure ring 116 is pressed. The pressure ring 116 drives multiple connecting rods 115 and multiple drive seats 114 to move, so that the drive seats 114 drive the locking member 111 to rise. At this time, the locking member 111 moves out of the locking groove on the inner tube 104, and the inner tube 104 can be removed from the outer tube 103.

[0026] Additionally, the sealing component 117 includes an abutment plate 118, a mounting plate 119, and a sealing gasket 120. The abutment plate 118 is fixedly connected to the outer tube 103 and located inside the outer tube 103; the mounting plate 119 is fixedly connected to the inner tube 104 and sleeved on the inner tube 104; the sealing gasket 120 is fixedly connected to the mounting plate 119 and located on the side of the mounting plate 119 closest to the abutment plate 118; when the inner tube 104 is installed in place, the sealing... The gasket 120 is pressed between the mounting plate 119 and the abutment plate 118. The gasket 120 seals the gap between the inner pipe 104 and the outer pipe 103, preventing dirt and other impurities from entering between the outer pipe 103 and the inner pipe 104, which could cause jamming or difficulty in disassembling the inner pipe 104 and the outer pipe 103. At the same time, it can also effectively prevent water from leaking from the connection between the inner pipe 104 and the outer pipe 103, ensuring the normal operation of the drainage structure.

[0027] When using the drainage structure of the retaining wall in water conservancy engineering of this utility model, the inner pipe 104 is installed inside the outer pipe 103 through the connecting member 107. At this time, the water flow is filtered by the mesh cylinder 105 and the sand and gravel 121 inside it to prevent the inner pipe 104 from becoming blocked and affecting drainage. When the mesh cylinder 105 is blocked, the pressure ring 116 is pressed to drive the connecting rod 115 and the drive seat 114 to move, so that the drive seat 114 drives the locking member 111 to move out of the locking groove on the inner pipe 104. At this time, the inner pipe 104 and the mesh cylinder 105 can be removed from the outer pipe 103, so as to facilitate the cleaning and replacement of the mesh cylinder 105 and avoid affecting the normal drainage of the drainage component 102.
