Description

Technical Field

[0001] This utility model relates to the field of foundation pit drainage technology, specifically a foundation pit sidewall drainage structure. Background Technology

[0002] An excavation pit is a pit dug at the foundation design location according to the base elevation and foundation plan dimensions. Before excavation, an excavation plan should be determined based on geological and hydrological data and the conditions of nearby buildings, and waterproofing and drainage work should be carried out.

[0003] During rain, especially when the rainfall is heavy, if the drainage effect inside the foundation pit is poor, the pit will be easily eroded by rainwater, causing soil erosion on the side walls and even leading to the collapse of the pit side walls. Traditional drainage methods mostly involve opening drainage channels or installing drainage pipes on the side walls of the foundation pit. However, because the surface of the foundation pit is mixed with rainwater, particles or debris will form, which will cause the drainage structure to be blocked. In addition, the structural strength of the drainage channels cannot be guaranteed during use, and they are prone to collapse.

[0004] Therefore, a drainage structure for the sidewall of the foundation pit is needed. Utility Model Content

[0005] The purpose of this utility model is to provide a drainage structure for the sidewall of a foundation pit, so as to solve the problems mentioned in the background art of drainage troughs being prone to collapse and drainage pipes being prone to blockage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drainage structure for the sidewall of a foundation pit, comprising a drainage pipe, a reinforcing mechanism fixedly installed on the side of the drainage pipe, and a filter replacement mechanism provided inside the drainage pipe; the filter replacement mechanism includes an installation sleeve, a limiting ring fixedly installed on the side of the installation sleeve, a positioning ring fixedly installed on the side of the installation sleeve, a positioning groove fixedly opened on the inner wall of the drainage pipe, the sides of the positioning ring and the limiting ring being mutually adapted to the inner wall of the positioning groove, an installation plate fixedly installed on the top surface of the installation sleeve, a handle fixedly installed on the fixed end surface of the installation plate, a drainage groove fixedly opened inside the installation sleeve, a connecting groove fixedly opened inside the installation sleeve, the connecting groove being connected to the drainage groove, and a filter plate fixedly installed on the inner wall of the installation sleeve.

[0007] Preferably, the reinforcing mechanism includes a retaining ring, and the retaining ring is fixedly installed on the side of the drain pipe.

[0008] Preferably, a reinforcing rib is fixedly installed on the side of the fixing ring, the side of the reinforcing rib is fixedly connected to the side of the drainage pipe, and a ground nail is fixedly installed on the side of the fixing ring. Two ground nails are installed on the side of each fixing ring, which can further improve the stability of the connection with the foundation pit.

[0009] Preferably, a connecting block is fixedly installed on the side of the drain pipe, a hinge is fixedly installed on the side of the connecting block, a cover plate is fixedly installed on the side of the hinge, and a rubber gasket is fixedly installed on the inner wall of the cover plate, which can effectively improve the sealing degree of the contact surface with the drain pipe.

[0010] Preferably, a buckle is fixedly installed on the side of the drain pipe, and the side of the buckle is snapped into the surface of the cover plate. The buckle can effectively improve the connection stability between the cover plate and the drain pipe, and further improve the structural strength.

[0011] Preferably, the cover plate has an installation groove on its surface, and an arc-shaped transparent acrylic plate is fixedly installed on the inner wall of the installation groove. The transparent acrylic plate allows for a clearer observation of the blockage inside the drain pipe, thereby improving the efficiency of handling blocked pipes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) When the drainage structure on the side wall of the foundation pit becomes blocked and needs to be cleaned, first open the buckle, then open the cover plate, then grip the handle and pull upwards to lift the mounting plate and mounting sleeve. At this time, the limit ring and positioning ring disengage from the positioning groove, and lift the filter plate installed on the inner wall of the mounting sleeve to remove the debris accumulated between the mounting sleeve and the filter plate. After cleaning, grip the handle to align the limit ring and positioning ring with the limit groove and make the three engage. Then the installation can be completed. At this time, close the cover plate. This can effectively improve the efficiency of cleaning impurities inside the drainage pipe.

[0014] 2) The drainage structure of the pit sidewall first installs the device on the pit surface with ground nails, and then improves the overall structural strength of the drainage pipe with fixing rings and reinforcing ribs to prevent the structure from being affected and damaged due to large water flow inside the drainage pipe. The rubber pad installed at the bottom of the cover plate can be tightly attached to the side of the drainage pipe to improve the sealing of the device, prevent water from overflowing, prevent the drainage effect from deteriorating, and improve the practicality and drainage effect of the device.
