Underground structure anti-floating system and construction method thereof

Abstract

The invention discloses an underground structure anti-floating system and a construction method thereof and is applied to the field of underground structures. According to the technical scheme, the underground structure anti-floating system is characterized by comprising a foundation trench and further comprising a plurality of vertical fender piles which are arranged along the periphery of the foundation trench, the vertical fender piles are close to one another and form a fender pile wall, the bottom of the foundation trench is provided with a plurality of cable-stayed piles buried in a soilbody, the cable-stayed piles are obliquely and downwards arranged, one ends of the cable-stayed piles are connected with the vertical fender piles, and the ends, far away from the vertical fender piles, of the cable-stayed piles extend to the middle of the foundation trench. The underground structure anti-floating system and the construction method thereof have the technical effects that the stability of the underground structure can be enhanced, and the anti-floating performance of the underground structure is improved.

Description

technical field [0001] The invention relates to the field of underground structures, in particular to an anti-floating system of an underground structure and a construction method thereof. Background technique [0002] There is a large amount of groundwater in the gaps of the soil and the fissures of the rock mass, and the groundwater will generate a buoyancy force on the underground structure or depression structure buried in or on the rock mass, such as the foundation pit For underground structures, if the self-weight of the underground structure is less than the upward buoyancy force generated by groundwater, the underground structure will arch or float up, causing cracks and water seepage in the underground structure, which will affect the normal use of the underground structure. [0003] In recent years, a large number of underground structures such as high-rise buildings with basements, underground garages, sunken squares, subways and underground shopping malls have be...
