Embodiment 1
[0065] A prefabricated underground garage, which includes a closed underground wall formed by mutually overlapping enclosure piles, the horizontal section of the underground wall is rectangular; in this embodiment, reinforced concrete sheet piles are specifically used as the enclosure pile.
[0066] According to the specific geological structure and standard requirements, the enclosure piles can also use steel piles such as steel sheet piles or similar sheet piles, steel pipe piles, H-shaped steel piles, or various types of cast-in-place piles constructed on site. Long auger bored piles, short auger bored piles for dry operation, cast-in-situ piles for mud retaining method, and cast-in-place piles for casing retaining method.
[0067] The underground garage also includes a top plate, a base plate, and four intermediate parking floors, and four permanent columns are arranged vertically in the underground garage; in other embodiments, the number of permanent columns can be adjus...
Embodiment 2
[0093] This embodiment is to construct the prefabricated underground garage described in Embodiment 1, and the symbol 90 in the drawings represents the ground.
[0094] The specific steps of construction are as follows:
[0095] (1) Please refer to image 3 and Figure 5 , the reinforced concrete sheet piles used as enclosure piles are sunk along the edge of the foundation pit to be excavated, the pile bottom elevation of the reinforced concrete sheet piles reaches the set elevation, and the adjacent reinforced concrete sheet piles overlap each other to form a closed underground wall 1. The horizontal section of the underground wall is rectangular; when other types of piles are used as enclosure piles, corresponding construction needs to be carried out according to the specific type of piles.
[0096] (2) Sink the temporary column 4 to the set position, so that the temporary column is arranged along an ellipse.
[0097] (3) In the area of the foundation pit to be excavate...

Abstract
The invention discloses an assembly type underground garage. The garage comprises underground walls, a top plate, a bottom plate and at least three middle parking layers. Permanent upright columns are vertically arranged in the underground garage. The top plate and each middle parking layer both comprises a purlin supporting the corresponding underground wall, an oval ring bracket abutting against the inner wall of the purlin, two first supporting beams and a plurality of second supporting beams, wherein the two ends of each first supporting beam abut against the oval ring bracket and are supported on the corresponding permanent upright column, and the second supporting beams are supported between the first supporting beam and the oval ring bracket. The bottom parking layer is arranged on the bottom plate. The bottom parking layer and each middle parking layer are both provided with a vehicle carrying board capable of moving. Reinforcing treatment is conducted between prefabricated components of the underground garage, the integrity of the underground garage structure is improved, and accordingly the anti-seismic property of the underground garage is improved. The invention further discloses a building method of the underground garage.
Description
technical field [0001] The invention belongs to the field of underground garage structure and construction, and in particular relates to an assembled underground garage and a construction method thereof. Background technique [0002] With the continuous expansion of the city scale, the number of family cars in the city continues to increase. Due to the development of less and less ground space, the development of underground garages has become a trend. In order to adapt to the rapid development of modern society and save construction costs , The prefabricated underground garage has also been developed rapidly. The prefabricated underground garage uses a large number of prefabricated parts, which can not only realize the standardization of garage accessories, but also realize large-scale production to reduce the manufacturing cost of prefabricated parts. When building an underground garage, prefabricated parts can be directly used for construction in the foundation pit, suppl...
