A method for constructing underground garages between residential buildings

Abstract

The invention provides a method for constructing an underground garage between residential buildings. The method comprises the following steps that: enclosing piles and middle upright post piles are pressed into the stratum in set positions; the pile tops of the upright post piles are positioned under a garage top slab; rotary jet grouting is performed above the position of the garage top slab; excavation is performed at the two sides of the garage to the garage depth; the excavation parts are used as underground excavation soil outlet openings; soil digging excavation is started under a cement soil layer from a garage entrance and exit part; after the excavation reaches a certain distance, a bottom slab or a side wall of a foundation pit is cast in an underground excavation completion region; a circle of corbels are manufactured on the top end of each upright post pile; sectional steel is put on the corbels arranged on the top ends of the adjacent piles; a top slab steel bar cage is bound; a prefabricated slab element is put under the steel bar cage and is used as a bottom die for casting to form the garage top slab; and an underground garage inner lining structure is constructed after the concrete maintenance is completed. The method has the advantages that under the condition of not influencing underground pipelines and upper part structures of a residential area, the underground garage can be completed through underground excavation; the periphery construction disturbance is small; and the environment pollution is avoided.

Description

technical field [0001] The invention relates to a method for constructing an underground garage between residential buildings, and belongs to the technical field of underground engineering. Background technique [0002] With the development of the economy and the improvement of people's living standards, the growth of motor vehicles is constantly breaking new records, and the problem of difficult parking is becoming more and more serious. Especially in the residential quarters built in the past few years, there is no underground parking lot, so there is no parking place for motor vehicles in the community. Parking on the side of the road not only occupies the lane, but is also unsafe. In order to alleviate the difficulty of parking, measures such as planning parking spaces on the roadside are mainly adopted at present. However, areas facing parking shortages are often located in prime locations in the city. Planning ground parking spaces often leads to traffic congestion and...

AI Technical Summary

Problems solved by technology

[0005] 1. Larger mechanical equipment is required for large-diameter pile foundation construction, which is not easy to work in residential areas;

[0006] 2. It requires a large construction space, and it cannot be constructed in densely populated areas of residential buildings;

[0007] 3. Large-scale construction machinery is very noisy, which is very disturbing;

[0008] 4. The construction period is long and the construction efficiency is low, so it is not suitable for working in residential areas
