Well point pipe light intelligent insertion device for river channel inner foundation pit dewatering

Abstract

The invention discloses a well point pipe light intelligent insertion device for river channel inner foundation pit dewatering. The device comprises a sectional well point pipe system, a static pressure power system, an intelligent control system and a movable operation platform. The upper end of a segment head pipe is connected to a pressure plate, the lower end is connected to a segment tail pipe, and a side end is connected with a water pump. A loop bar type pressure shaft pushes the pressure plate to apply static pressure to the segment head pipe, and meanwhile water is conveyed into the segment head pipe through the water pump, so that the segment tail pipe is perpendicularly inserted into soil and forms a well point hole through water flushing. By adding the section standard pipe between the section head pipe and the section tail pipe, the precipitation requirements of different depths are met. The device is simple in structure and light and handy in structure, well point hole drilling and well point pipe placement are carried out in parallel, and the double benefits of quickening the construction progress and reducing the construction cost are achieved.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a light intelligent insertion device for a well-point pipe used for dewatering a foundation pit in a river channel. Background technique [0002] As an important part of construction engineering, the foundation pit is an important guarantee for the stability and reliability of the main structure of the building. In the process of excavating the foundation pit, if the surface and groundwater in the foundation pit are not removed in time, the construction environment of the foundation pit will gradually deteriorate, the bearing capacity of the foundation will be reduced, and the soil wall of the foundation pit may even be induced to collapse. Therefore, in order to ensure the quality of foundation pit construction, it is necessary to do a good job in the corresponding dewatering construction work. [0003] Light well point dewatering is one of the commonly used co...

AI Technical Summary

Problems solved by technology

For the drilling of drilling rigs, mud or high-pressure water circulation is required on the job site, and large-scale machinery and equipment are required. The construction environment is poor, the labor intensity is high, the construction efficiency is low, and the cost is high.

For high-pressure water impacting holes, in soft soil or filled soil that is prone to collapse or shrinkage holes, this method is difficult to construct, and there are difficulties in hole formation. And other issues

[0005] In view of the technical and economic disadvantages of the traditional light well point dewatering technology, a light intelligent insertion device is urgently needed to reduce labor intensity and construction costs, ensure construction quality, and improve construction efficiency
