Anti-floating underground garage only with supporting piles and construction method of anti-floating underground garage

Abstract

The invention discloses an anti-floating underground garage only with supporting piles and a construction method of the anti-floating underground garage, and belongs to the technical field of underground garage construction. The anti-floating underground garage comprises an underground garage main body which is composed of a garage bottom plate, garage wall plates and a garage top plate; cast-in-situ bored piles are arranged at the side edge of the underground garage main body, and cement jet grouting piles are arranged between the adjacent cast-in-situ bored piles; and pile top longitudinal bars are arranged at the upper ends of the cast-in-situ bored piles, and upper steel bars and lower bars are arranged at the side edge of the garage top plate. Measures are taken from the initial construction stage, the upper steel bars, the lower steel bars and the pile top longitudinal bars are connected in penetrating and inserted modes, welded and fixed, thus it is guaranteed that the garage top plate and the cast-in-situ bored piles form a whole, and the effect of overall reinforcement of the underground garage main body is achieved; and the lower ends of the cast-in-situ bored piles and the cement jet grouting piles resist groundwater jointly, it is guaranteed that the groundwater has no buoyancy effect on the underground garage main body, and the anti-floating safety of the garage iseffectively improved.

Description

technical field [0001] The invention relates to the technical field of underground garage construction, in particular to an anti-floating underground garage with only support piles and a construction method thereof. Background technique [0002] In some areas of China where there is a lot of rain, due to the limited drainage capacity of the land and the lack of drainage capacity of the underground waterway, the rainwater often flows into the basement or underground garage, forming water accumulation in the basement and underground garage, increasing the drainage pressure of the underground garage At present, for the construction of large-span underground garages, it is mainly to overcome the buoyancy generated by groundwater on the garage. Groundwater generation includes surface water leakage and groundwater flow. Since the underground garage is a box-shaped concrete structure, it is vulnerable to groundwater and groundwater during construction. The effect of rainwater or su...

[0002] In some areas of China where there is a lot of rain, due to the limited drainage capacity of the land and the lack of drainage capacity of the underground waterway, the rainwater often flows into the basement or underground garage, forming water accumulation in the basement and underground garage, increasing the drainage pressure of the underground garage At present, for the construction of large-span underground garages, it is mainly to overcome the buoyancy generated by groundwater on the garage. Groundwater generation includes surface water leakage and groundwater flow. Since the underground garage is a box-shaped concrete structure, it is vulnerable to groundwater and groundwater during construction. The effect of rainwater or surface water produces buoyancy. If measures such as water isolation and drainage are not adopted, the effect of groundwater on the buoyancy of the garage cannot be removed.
