Drainage system of housing construction site and use method

Abstract

The invention relates to a drainage system of a housing construction site and a use method. The drainage system comprises a foundation pit, wherein the foundation pit is formed in the construction site, a plurality of water seepage pipes which surround the foundation pit are inserted in the construction site, the bottom ends of the water seepage pipes communicate with a water suction pump which is arranged on the construction site in advance through water suction pipes which are arranged in advance, and the peripheries of the tops of the water seepage pipes communicate with a water injection pump which is arranged on the construction site in advance through water injection pipes which are arranged in advance; a plurality of groups of water seepage holes which are arranged at intervals are formed in the peripheries of the bottoms of the water seepage pipes and are obliquely coiled on the peripheries of the water seepage pipes in the length direction of the water seepage pipes; and plugging pipes which are attached to the inner walls of the water seepage pipes are rotatably embedded in inner cavities of the water seepage pipes, driving assemblies which are used for driving the plugging pipes to rotate are arranged in the inner cavities of the water seepage pipes, avoidance holes which extend in the length direction of the plugging pipes are formed in the plugging pipes, and the avoidance holes can be aligned with any group of water seepage holes in the process of rotating along with the plugging pipes. According to the drainage system, the construction difficulty in the foundation pit can be reduced, and the condition of collapse of the side wall of the foundation pit is reduced.

Description

Technical field [0001] The present application relates to the field of construction, in particular, in particular, a standard construction site drainage system and method of use. Background technique [0002] With the development of society, the continuous improvement of science and technology, the improvement of economic level, more and more housing buildings, solve people's housing problems, improve the quality of people's living environment. [0003] Housing buildings need to excavate foundation pits during construction, foundation pits is the foundation design position according to the solar pit excaving the base elevation and the foundation plane size. When the depth of the foundation pit is below the natural groundwater level, the groundwater will continue to penetrate into the foundation pit from the base pit side and the bottom of the foundation pit. In order to ensure that the foundation pit can be constructed under dry conditions, the slope is stopped, the base flow, th...

Problems solved by technology

[0004] However, the inventor believes that groundwater continuously infiltrates into the foundation pit from the side walls and bottom of the foundation pit, which indicates that the soil on the side walls of the foundation pit and the bottom of the foundation pit contains a large amount of water, which will easily increase the difficulty of construction, and even easily lead to the collapse of the foundation pit. Collapse of side walls; therefore, room for improvement
