Structure suitable for large diameter underground vertical shaft type parking garage and construction method of structure

Abstract

The invention provides a structure suitable for a large diameter underground vertical shaft type parking garage and a construction method of the structure. The parking garage structure includes a plurality of high-pressure jet grouting piles, reinforced concrete filling piles and garage inner walls, wherein the high-pressure jet grouting piles are circumferentially arranged along the inner wall ofan underground vertical shaft, the reinforced concrete filling piles are arranged between two adjacent high-pressure jet grouting piles and face towards the inner side of the underground vertical shaft, and the garage inner walls are arranged on the inner sides of the reinforced concrete filling piles; and wherein a plurality of vertical columns extending to the reinforced concrete shaft bottom are arranged in the circumferential direction of the position where the underground vertical shaft and the garage inner walls are concentric circles, the vertical columns are connected with the garageinner walls through a plurality of horizontal supporting rod pieces in the vertical direction, and the upper and lower adjacent horizontal supporting rod pieces are connected through inclined rods. The construction method is based on the parking garage structure, a fabricated reverse order construction method is adopted, and construction is convenient; and an underground vertical shaft type parking garage makes full use of underground space, is used for solving the problem of parking difficulty in prosperous downtown areas and old residential areas, and the aboveground part of the vertical shaft type parking garage is only for vehicle entrance and exit, and land conservation is achieved.

Description

technical field [0001] The invention belongs to the technical field of building structure engineering, and in particular relates to a large-diameter underground shaft type parking garage structure and a construction method thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, the car ownership continues to increase, and the contradiction with the lagging construction of urban parking facilities is very prominent. Building a three-dimensional garage is a feasible way to save urban space and alleviate parking difficulties. However, with the development of the urbanization process, the land resources in the central area of ​​the city have become more scarce, especially in the old residential areas of the old city. Due to the limitation of the site, the newly built three-dimensional garage on the ground also has limited space and occupies the extremely limited activity space of residents. problem. Contents...
