Embodiment Construction

[0038] Refer to attached figure 1. The shaft wall structure of the elevator-type underground three-dimensional garage shaft is a reinforced concrete composite shaft wall, which is composed of a reinforced concrete inner shaft wall 2 and a reinforced concrete outer shaft wall 1, the outer shaft wall is composed of piles or underground continuous walls, and the inner surface of the outer shaft wall It is chiseled until its steel bars are exposed, and the steel bars on the inner well wall and the outer well wall are welded and / or bound together, the inner well wall is on the inner side of the outer well wall, and the inner well wall is formed by pouring in multiple sections from top to bottom; In this embodiment, the multiple sections are respectively represented by the following symbols 20-1, 20-2, 20-3, 20-4, 20-5, 20-6, 20-7; The upper end 21 of that section presses out the lower end 22 of the section above and forms in this area a ring-shaped convex transverse structural sup...

Abstract

The invention provides an elevator-type underground stereo garage shaft. A shaft wall of the elevator-type underground stereo garage shaft is a reinforced concrete composite shaft wall; an external shaft wall is formed by piles or underground continuous walls; reinforcing steel bars of an internal shaft wall are connected with reinforcing steel bars of the external shaft wall; the internal shaft wall is formed by casting multiple sections divided from top to bottom; the relationship between two adjacent sections is that the upper end of the lower section is pressed outside the lower end of the upper section; and an annular and convex lateral structure support protruding from the surface of the internal shaft wall is formed in the region. The invention further provides a construction method of the shaft; the external shaft wall is constructed in one time before excavating foundation ditches to form a vertical structure support; and the internal shaft wall is constructed section by section from top to bottom under the soil retaining and water stopping function of the external shaft wall, so as to finish shaft structure construction and form the annular and convex lateral structure support, and the internal shaft and the external shaft wall form an integer. The method is simple, safe and low in cost; the constructed shaft is firm in structure, and the depth can be up to 50 meters; the city land utilization is improved; and the urban parking problem is solved.

Description

technical field [0001] The invention relates to the technical field of underground construction engineering, in particular to an elevator-type underground three-dimensional garage and a construction method thereof. Background technique [0002] At present, there is an intelligent tower-type stereo garage (PCS type) with a high degree of automation and space utilization in China. Because it occupies ground space, the tower height is between 30-50 meters, which is relatively limited by the urban construction planning management department. Many, unable to scale development. In order to solve the bottleneck problem that restricts the development of the tower-type three-dimensional garage, if all the three-dimensional garages are built 30-50 meters underground, since the parking shaft is built at a depth of 50 meters underground, the underground shaft requires structural safety, leak-proof and anti-seepage, such as According to the existing construction method, the cost and tec...
