Construction method for barrel type underground garage

Abstract

The invention relates to a construction method of a cylindrical underground garage, belongs to the technology field of underground buildings, and aims to solve the technical problems of constructing an underground garage in an area with large population, small space and crowed buildings. The construction method comprises the following steps of: (1) performing preparation work including reinforcing the soil in a certain range around a well mouth, preparing a well mouth ring beam and a well drilling platform, and placing equipment and leveling; (2) drilling an underground vertical well pit; (3) performing slurry replacement when the drilled well reaches a designed depth and diameter; (4) installing a reinforced concrete well wall by sinking according to a suspension method; (5) correcting the verticality of the well wall after the well is sunk to a predetermined position, and backfilling the wall; (6) pumping out the counterweight water in the well pit; and (7) installing the in-well equipment and the ground appurtenant facilities. The inventive construction method has the advantages of low construction cost, short construction period, low construction difficulty, wide application range, and low influence on peripheral environment.

Description

technical field [0001] The invention relates to underground building technology, more specifically to the building technology for building a tubular underground three-dimensional garage. The underground building technology is also applicable to the construction of tubular underground shaft stores such as underground warehouses, underground oil depots, and underground cold stores. Background technique [0002] With the advancement of my country's urbanization process and the development of social economy, the number of cars has gradually increased, and the problem of "difficult parking" has become prominent. In order to solve this problem better, it is common practice to build underground garages under urban high-rise buildings, but it still cannot fundamentally solve the difficult problem of parking. Subsequently, some related units have developed the above-ground three-dimensional garage, that is, a three-dimensional parking lot is built above the ground to alleviate the p...

AI Technical Summary

Problems solved by technology

The ground parking lot has been slow to advance due to the overall planning of the city, the impact on the landscape, and the rise in land prices, and has not completely solved the problem of difficult parking

Invention patent ZL03116973.2 proposed the concept of an underground three-dimensional garage, and announced a construction method for an underground garage. It mainly introduced the construction process of an underground three-dimensional garage. The ground conditions are quite restrictive, and the construction quality is difficult to control, and the impact on the surrounding environment during construction is also unavoidable. It is difficult to successfully complete the construction of the underground three-dimensional garage

[0012] The framing joints of the underground diaphragm wall are prone to leakage;

[0013] The verticality of the underground diaphragm wall is not enough to meet the accuracy requirements of later equipment installation;

[0014] ●The technical requirements for the bottom sealing of the cylinder are high, and the effect is not easy to meet the requirements;
