Problems solved by technology

[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 be arched or floated up, causing cracks and water seepage in the underground structure, which will affect the normal use of the underground structure

Embodiment 1

[0035] Embodiment 1: a kind of underground structure anti-floating system, such as figure 1 , including the foundation pit 1, and also includes several vertical retaining piles 2 arranged along the periphery of the foundation pit 1, each vertical retaining pile 2 is adjacent to each other and forms a protective pile wall, so as to protect the periphery of the foundation pit 1 and reduce the The foundation pit 1 is subjected to the pressure of the soil body 10 . The bottom of the foundation pit 1 is provided with a number of cable-stayed piles 3 embedded in the soil 10. The cable-stayed piles 3 are arranged obliquely downward and the lower end extends to the middle of the foundation pit 1. In this embodiment, the inclination of the cable-stayed piles 3 is set is 30°. The higher end of the cable-stayed pile 3 is connected to the bottom of the vertical guard pile 2, and the vertical guard pile 2 and the cable-stayed pile 3 are all pierced with steel cages to improve the structur...

Embodiment 2

[0041] Embodiment 2: a kind of construction method that is used for the anti-floating system of underground structure in embodiment 1, comprises the following steps:

[0042] The operator first uses the excavator to excavate the soil 10 to form the required foundation pit 1, and then drills a number of cable-stayed holes slanting downward toward the middle of the foundation pit 1 at the bottom of the foundation pit 1 along the periphery of the foundation pit 1. Put steel reinforcement cage inside, and pour concrete to form cable-stayed pile 3. Afterwards, the bottom of the foundation pit 1 is excavated and filled with fine sand to form a buffer layer 9, and the upper surface of the buffer layer 9 is filled with soil to re-form the bottom of the foundation pit 1.

[0043] Then backfill a layer of soil body 10 to the inner side wall of the foundation pit 1, and fill the bottom of the foundation pit 1 and the middle and lower parts of the side wall of the foundation pit 1 with gr...

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...
