Anchor foundation pit drainage system and construction method thereof

Abstract

The invention discloses an anchor foundation pit drainage system and a construction method thereof. The anchor foundation pit drainage system adopts a multistage drainage system structure, and comprises a pit top drainage structure, a slope drainage structure and a pit bottom drainage structure; the pit top drainage structure comprises a intercepting ditch and a water retaining wall; the slope drainage structure is arranged on a peripheral slope of a foundation pit, and comprises a drainage pitch and a water pipe; the pit bottom drainage structure is positioned at the bottom of the foundationpit, and comprises a water gathering ditch and a water collecting well; different drainage structures are arranged in each layer of structures according to specific structures; all the drainage structures are combined to form one complete drainage system; and the whole system is simple in structure. The invention further discloses a construction method of the anchor foundation pit drainage system;each grade of the drainage system is constructed one by one through a construction mode from top to bottom; construction is simple, stable and reliable; drainage is smooth; and the effects of damp prevention and drainage are achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of building foundation pit drainage, in particular to an anchor foundation pit drainage system and a construction method thereof. 【Background technique】 [0002] The foundation pit is an earth pit excavated at the foundation design position according to the elevation of the bottom of the foundation pit and the plane size of the foundation. After the excavation of the ordinary foundation pit is completed, the foundation pit needs to be waterproofed, otherwise it will cause water seepage in the foundation pit and affect the normal use of the equipment in the foundation pit. Since there are uncertain factors in the leakage time and water seepage amount in the foundation pit, it will seriously affect the normal use of the foundation pit, and re-waterproofing is time-consuming, laborious and costly, which affects the orderly progress of normal production activities. [0003] During the excavation of deep found...
