High-rise deviation rectifying drainage well construction device, pressure relief well construction device and deviation rectifying method

Abstract

The invention provides a high-rise deviation rectifying drainage well construction device, a pressure relief well construction device and a deviation rectifying method. The high-rise deviation rectifying drainage well construction device comprises an outer casing pipe, an inner pipe and a pipe tip, the pipe tip comprises a large-diameter pipe, a circular steel plate, a guide pipe fitting and a small-diameter pipe, the large-diameter pipe, the circular steel plate and the small-diameter pipe are coaxially welded and fixed in sequence, the guide pipe fitting is in a horn shape and fixed outsidethe small-diameter pipe in a sleeving mode, the large end of the guide pipe fitting is welded and fixed to the circular steel plate, the small end of the guide pipe fitting is welded and fixed to thesmall-diameter pipe, the outer diameter of the outer casing pipe is matched with the inner diameter of the large-diameter pipe, one end of the outer casing pipe is inserted into the large-diameter pipe, a lubricating oil layer is arranged between the outer casing pipe and the large-diameter pipe, and the inner pipe is inserted into the outer casing pipe. According to the high-rise deviation rectifying drainage well construction device, the pressure relief well construction device and the deviation rectifying method, the device structure is simple, the cost is low, the method is easy to operate, construction time is short, and safety is high.

Description

technical field [0001] The invention relates to the technical field of deviation correction for high-rise buildings, in particular to a high-rise deviation correction dredging well construction device, a relief well construction device and a deviation correction method. Background technique [0002] In order to save limited land resources and at the same time ensure a comfortable building area for residents, the building expands from the simple plane area to the height of the space. Therefore, the total height of the building is constantly refreshing the height record of the built building, which is invisible. Higher requirements are placed on the foundation of the building. In real life, due to the fact that many buildings do not have enough foundation surveys before the design, or even no foundation surveys, etc., the buildings have problems of varying degrees after construction, such as uneven settlement of the foundations leading to cracks in the walls, and even How to ...

AI Technical Summary

Problems solved by technology

[0003] Precipitation rectification is a commonly used method in building rectification. Its principle is to use the method of extracting groundwater to rectify the deviation, rely on the extraction of water in the soil, reduce the groundwater level, reduce the pores of the soil to speed up the compression of the soil, and increase the compactness of the soil. Make the soil under the building foundation subside to adjust the uneven settlement of the building and achieve the purpose of correcting the deviation, but the existing methods have the problems of complicated equipment, high cost, complicated operation and long construction time
