Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a well point dewatering insertion hole device. BACKGROUND

[0002] Well point dewatering is a method of artificially lowering the groundwater level, also known as "well point dewatering method". Before excavation of the foundation pit, a certain number of filter pipes are buried around the foundation pit, and water is pumped out using pumping equipment to keep the excavated soil dry. The types of well points used include light well points, jet well points, electro-osmotic well points, pipe well points, and deep well points, which are widely used.

[0003] The traditional well point dewatering has the following shortcomings in the construction process. During the well point dewatering construction, the insertion pipe needs to be inserted into the pre-set hole. The hole is generally formed by high-pressure water flushing. After the hole is formed, the inner wall of the hole lacks support, which may cause the hole to deform due to collapse, making it difficult to lower the well pipe to the designed elevation, affecting the construction progress and increasing the construction difficulty. At the same time, the material requirements for the well pipe are high, resulting in high cost. Therefore, we propose a well point dewatering insertion hole device. SUMMARY

[0004] The technical problem to be solved by the present application is to overcome the existing defects and provide a well point dewatering insertion hole device. After determining the insertion hole position of the well point dewatering, the sleeve ring is inserted into the ring groove from the bottom of the sleeve, and the sleeve ring and the filter cover are inserted into the bottom end of the sleeve. At this time, the bowl buckle is buckled to the bottom of the sleeve, which plays a sealing role on the bottom of the sleeve. The power end of the drilling machine is operated to press the sleeve into the insertion hole position. The prepared insertion pipe is inserted between the guide wheels, which can guide and limit the insertion process of the insertion pipe to ensure its vertical movement. When the insertion pipe is inserted to the designed depth, its end will be inserted into the filter cover and will open the bowl buckle, which will not affect the overall extraction of the sleeve. After the insertion pipe is inserted in place, the lifting buckle top is connected to the lifting equipment for vertical lifting, so that the sleeve can be removed from the hole. The insertion pipe inserted in place remains in the hole, and the insertion pipe operation is completed. After lifting, the filter cover is connected to the bottom end of the insertion pipe, which can play a filtering role during drainage and reduce the entry of silt. The sleeve is reusable, and the insertion pipe end is connected and connected to the water pumping assembly after the insertion of each group of pipe bodies is completed. The dewatering operation can be performed, avoiding the problem of difficult insertion of the insertion pipe caused by the collapse of the hole wall. Any material can be used for the insertion pipe structure, reducing the use cost.
