Easy-to-disassemble precipitation well structure and assembly method

Abstract

The invention discloses an easy-to-disassemble precipitation well structure and an assembly method. The easy-to-disassemble precipitation well structure comprises a precipitation well body, a precipitation well base and connecting ribs; through holes are axially formed in the pipe wall of the precipitation well body in a penetrating manner; the precipitation well base blocks the bottom end of theprecipitation well body, sleeves are fixed to the positions, right opposite to the through holes, of the precipitation well base, and the sleeves are correspondingly inserted into the through holes; and the connecting rib penetrates through the through holes, and the bottoms of the connecting ribs are in threaded connection with the sleeves. According to the structure and the assembly method, by means of the connecting mode among the connecting ribs, the precipitation well base and the precipitation well body, the precipitation well can be conveniently assembled and disassembled, and multiplepipe sections can be combined into the complete precipitation well body through the connecting ribs so that the pipe sections can be conveniently taken out together during backfilling, and the precipitation well body can be conveniently recycled; and through the arrangement of stiffening rings and a capping sleeve, the integrity of a precipitation well is improved, and the precipitation well is not prone to deforming.

Description

technical field [0001] The invention belongs to the field of engineering construction, and in particular relates to an easily disassembled dewatering well structure and an installation method. Background technique [0002] For structures with basement space, such as airport terminals, airport parking buildings, large businesses, high-rise residences, etc., the construction of these buildings will involve excavation of foundation pits. Before excavation of foundation pits, the groundwater level must be lowered. Especially in geology with abundant water sources, it is necessary to set up a large number of precipitation wells to dewater the foundation pit. The production of conventional dewatering wells requires a large number of steel bars, steel mesh sheets, filter screens, etc., as well as a large number of welding processes, mechanical connection processes, and large-scale mechanical hoisting. The cage has also become a waste material, especially after the bottom plate con...

Problems solved by technology

The production of conventional dewatering wells requires a large number of steel bars, steel mesh sheets, filter screens, etc., as well as a large number of welding processes, mechanical connection processes, and large-scale mechanical hoisting. The cage has also become a waste material, especially after the construction of the base plate is completed, the dewatering well needs to be backfilled, and most of the materials are filled underground, which is a huge waste in terms of construction period and cost
