Description

Underground parking system and construction method thereof

Technical Field

The invention relates to an underground parking system and a construction method of the underground parking system, and belongs to the technical field of construction of parking systems.

Background

Along with the acceleration of the urban process, people flow and logistics tend to be concentrated, the demands of storing and keeping articles are greatly improved, and parking spots need to be widely built in different areas of the city. The ground three-dimensional parking system is adopted for the construction of the existing parking spot, and the ground resources can be utilized to the maximum extent by utilizing the vertical space, so that the problem of insufficient ground space is effectively solved.

However, the ground three-dimensional parking system has influence on the urban landscape, and damages the urban overall planning; the above-ground three-dimensional parking system is dependent on advanced intelligent technology and equipment for storing and taking articles, the access speed is low, and the flow is long; the technical requirement of the ground three-dimensional parking system is high, and the operation and maintenance management difficulty is high; the construction period of the ground parking structure is long, and the construction cost is high.

In order to meet the increasing parking demands of cities and simultaneously avoid occupying the ground space, a novel underground three-dimensional parking system which is rapid in research and development, low in cost, convenient to store and take and convenient to operate and maintain is required.

For the construction of an underground three-dimensional parking system, the prior art has the following schemes:

scheme one: the multi-layer underground garage is built on an underground floor of a building, the number of entrances and exits is small, vehicles can automatically find parking places and park after entering the underground garage, and only a small number of vertical traffic channels are arranged between each layer of underground garage. .

Scheme II: an underground elevator shaft is built in an open caisson mode, and vehicle transportation is achieved through a vertical elevator.

Scheme III: the underground parking pipe gallery is formed by driving water stop piles into the soil, soil bodies on two sides are stabilized through the inner support, the underground pipe gallery and other underground structures are further built, and the parking space is usually the same as the ground parking.

The main disadvantages of the prior art are as follows:

1. the existing underground parking engineering construction needs to be carried out with water stop piles firstly, then support and then back cover, and therefore the construction cost is high, the construction period is long, and the influence on the surrounding environment is great. This is the most significant problem restricting the development of underground construction.

Along with the transformation requirements of the construction engineering industry, the construction industrialization is required to be gradually realized, and the assembly type construction is pushed. At present, the assembly type building on the ground engineering is widely popularized. The assembly type underground engineering mainly uses tunnel segments, and requires complex and high-cost construction machinery.

2. The existing multi-layer parking system is complex in structure and poor in running stability.

3. In the existing underground structure, rainwater can flow into the underground structure through an overground entrance in rainy season.

4. At present, the assembled tunnel segment structure and the open caisson structure are all circular cross sections, and the circular cross sections can be better suitable for the underground water and soil pressure. But multiple circular cross sections do not allow for cell parallel expansion. The rectangular cross section can be expanded in parallel, but the rectangular cross section is difficult to bear huge underground water pressure, soil pressure and buoyancy, and no rectangular assembled underground structure exists at present.

5. The existing parking frame is of a vertical supporting structure, and when the number of layers of the goods shelf is large, the running stability is poor and the anti-seismic performance is poor.
