Problems solved by technology

At present, most of the existing underground parking garages use reinforced concrete piles combined with reinforced concrete inner supports as the enclosure structure, but the enclosure structure will lose its function after the completion of the underground garage, and the enclosure structure cannot be used for secondary use, causing great damage. Waste of resources; under the background that the country vigorously promotes the promotion of prefabricated buildings, the scientific and reasonable use of steel structures and prefabricated components for the construction of underground parking garages is in line with the concept of sustainable development

Abstract

The invention discloses a prefabricated type foundation pit support structure for an environment-friendly underground garage. The prefabricated type foundation pit support structure is characterized in that the prefabricated type foundation pit support structure comprises prefabricated supporting piles, prefabricated profile steel annular supports and a prefabricated profile steel coping annular beam, the prefabricated profile steel annular supports are arranged on the inner walls of the prefabricated supporting piles, and the prefabricated profile steel coping annular beam is arranged at thetop ends of the prefabricated supporting piles. Environment-friendly underground garage supporting is conducted by adopting the prefabricated elements, after the underground garage is completed, the prefabricated elements can be recycled and reutilized, and therefore the prefabricated type foundation pit support structure has the characteristics of being economical and environmentally friendly; the installing mechanical degree of the prefabricated elements is high, and the operation environment is safe and comfortable; and the prefabricated elements do not need to be maintained after being installed, the next process can be conducted, and the construction period can be greatly shortened.

Description

technical field [0001] The invention relates to a foundation pit enclosure structure in the field of foundation and foundation engineering, in particular to a prefabricated foundation pit enclosure structure for an environment-friendly underground garage. Background technique [0002] With the acceleration of the urbanization process, the scale of the city continues to expand, resulting in an overload of urban population, traffic congestion, increasing road congestion, and serious environmental pollution, which has added enormous pressure to urban construction and development. In the current situation where urban land prices are getting more and more expensive, it is a great waste of resources to occupy limited ground space to build parking lots. As an above-ground space, it should provide people with an elegant natural environment and a comfortable living space as much as possible, and the underground development of the parking lot is an inevitable choice for modern parking...
