Subsurface deep space parking well structure for soft soil foundation

Abstract

A subsurface deep space parking well structure for a soft soil foundation is characterized in that single-axis or multi-axis cement stirring piles or SMW construction method piles with the pile diameter being 0.5 m to 1.2 m and the pile length exceeding the parking well depth by 1 m to 10 m serve as a peripheral stopping water curtain, drilling cast-in-place piles or occlusive piles with the pile diameter being 0.7 m to 1.5 m and the pile length exceeding the parking well depth by 8 m to 30 m serve as an outer wall, a reinforced concrete inner wall with the thickness of 0.3 m to 0.8 m is poured in a segmented form erecting manner from top to bottom or from bottom to top, the well bottom is a reinforced concrete bottom plate or plain concrete bottom sealing layer, the plane is of a square or rectangular well structure, and a stopping water belt composed of cement stirring piles or high-pressure rotary spraying piles being 5 m to 10 m is laid below the bottom seal layer. Compared with the prior art, the structure is used in the urban downtown areas with the national coastal soft soil area, and the beneficial effects that the well bottom soil layer is free of upwelling, the needed construction site is small, construction equipment is simple, the construction speed is high, engineering cost is low, and water leakage is avoided are achieved.

Description

technical field [0001] The invention relates to the construction field, in particular to an underground deep space parking well structure for soft ground. Background technique [0002] As we all know, the difficulty of parking in cities is a bottleneck of current urban development, and it is also an important popular project, especially in cities with soft soil foundations in the eastern coastal areas of my country. For parking, there is basically no basement or only one basement for parking. Nowadays, even if the roadside is full of private cars at night, it still cannot meet the growing demand for private car parking. Contents of the invention [0003] The invention provides an underground deep space parking well structure for soft soil foundations, which can be used in the downtown area of ​​cities with soft soil foundations along the coast of my country, and has the advantages of small required construction site, no upwelling of the bottom soil layer, simple constructio...
