[0029] The cover plate 3 includes a circular disk body and an annular limiting strip fixed in the center on the bottom surface of the disk body; the diameter of the disk body is larger than the outer diameter of the casing 1, and a plurality of rows of water collecting hole groups are arranged on the disk body from its center to its edge, and each row of water collecting hole groups is composed of a plurality of arc-shaped water collecting holes evenly distributed along the circumferential direction; an annular limiting strip is fixed in the center on the bottom surface of the disk body, and the outer diameter of the annular limiting strip is adapted to the inner diameter of the casing 1, so that the cover plate 3 is covered at the top opening of the casing 1, and its annular limiting strip is embedded in the inner side of the casing 1, so that the cover plate 3 is easy to open and is not easily displaced by external collision force.

[0030] In this embodiment, the cover plate 3 is cut from a steel plate of the same material as the casing 1, and the water collection holes are processed. Specifically, the cover plate 3 has a thickness of 5 mm and a diameter of 1100 mm. Four circles of water collection hole groups are arranged from the center of the cover plate 3 to the outer edge.

[0039] See also Figure 8 The specific construction process of using the anti-collapse reusable open drainage well equipment to complete the drainage operation is as follows:

[0040] S1. Construction preparation: Before construction, determine the diameter, depth, quantity and other construction parameters of the open drainage water collection equipment according to the construction geological conditions, groundwater level and drainage volume; process the corresponding specifications, dimensions and quantity of water collection wells, and transport the water collection well equipment to the site after processing;

[0041] S2. Determine the construction plan: According to the engineering drawings and the actual situation on site, locate and lay out the lines, and clarify the specific installation and construction locations of each water collection well on site;

[0042] S3, drainage operation: excavate the earthwork according to the positioning of step S2, and excavate in layers according to the soil conditions and the depth of the foundation pit; after the excavation is completed, use a crane to lift and transport the casing using the lifting ear holes, lift it to the designated position and lower it, and backfill the surrounding earthwork behind the casing. It should be noted that the top elevation of the water collection well should be 20 cm higher than the upper opening of the foundation pit to prevent the water collection well from being buried; excavate the drainage ditch below the casing to connect the water collection well with the drainage ditch; the width of the drainage ditch The depth is determined according to the drainage volume and flow rate to ensure smooth drainage; the appropriate water pump model and quantity are selected according to the drainage volume; the water pump is installed in the casing of the water collection well and placed on the wire mesh to ensure that the water inlet of the water pump is lower than the lowest water level of the water collection well so that the accumulated water can be pumped out in time. The cover plate placed above the casing can effectively protect the water pump and prevent construction debris from entering the water collection well. A drainage ditch is set outside the foundation pit to intercept surface water and rainwater; the water collection wells are arranged in multiple locations according to the construction location to form a complete water collection and drainage system;

[0043] S4. Construction monitoring: After the construction of the water collection well is completed, the accumulated water in the water collection well is pumped out by a water pump and discharged outside the foundation pit. During the discharge process, it is necessary to control the water discharge speed and direction of the water pump to prevent the impact on the surrounding environment. At the same time, the drainage system should be inspected and maintained regularly to ensure unobstructed drainage;

[0044] S6. Construction completion: When the dewatering work is completed, take out the water pump, use the lifting ear holes on the casing to take out the casing, and carry out necessary cleaning and maintenance work for the next use of the equipment.
