Underground pipe rack prefabrication assembly structure

Abstract

The invention discloses an underground pipe rack prefabrication assembly structure. The underground pipe rack prefabrication assembly structure comprises two pairs of blind hole T-shaped slots formedin the top surface of an underground pipe rack and slide plates on the bottom surface of the underground pipe rack, wherein the blind hole T-shaped slots are perpendicular to an opening of the underground pipe rack in direction; T-shaped blocks are arranged in the blind hole T-shaped slots; circular rings arranged above the T-shaped block extend out of upper portions of the T-shaped slots; the direction of the two or more slide plates, which are metal plates, is parallel to the blind hole T-shaped slots; and the slide plates are bulged out of the bottom surface of the underground pipe rack by1-3 mm. According to the underground pipe rack prefabrication assembly structure disclosed by the invention, on one hand, a structure form of a hanging point above is changed, and T-shaped slots and T-shaped blocks are arranged on the top surfaces of the two sides, on the other hand, the bugled slide plates, which are additionally arranged, can slide underground while hoisting cannot be performed,so that the assembly is simple, convenient and quick, and construction efficiency is improved.

Description

technical field [0001] The invention belongs to the field of pipe galleries, and in particular relates to a prefabricated assembly structure of an underground pipe gallery. Background technique [0002] The underground pipe gallery is a public tunnel used for centralized laying of municipal pipelines such as electricity and communications in the city. The existing underground pipe gallery is a square structure with openings on both sides. It is hoisted and connected to each other during laying. The current hoisting method The hook is installed on the roof of the pipe gallery. This structure has the following defects: (1) During the prefabrication process of the pipe gallery, there will be conflicts between the hook and the outer formwork, which is not conducive to formwork support. (2) During on-site installation, the protruding part of the hook will affect the waterproof construction of the outer wall; (3) In the later use process, the hook is the weak point of the structur...

[0002] The underground pipe gallery is a public tunnel used for centralized laying of municipal pipelines such as electricity and communications in the city. The existing underground pipe gallery is a square structure with openings on both sides. It is hoisted and connected to each other during laying. The current hoisting method The hook is installed on the roof of the pipe gallery. This structure has the following defects: (1) During the prefabrication process of the pipe gallery, there will be conflicts between the hook and the outer formwork, which is not conducive to formwork support. (2) During on-site installation, the protruding part of the hook will affect the waterproof construction of the outer wall; (3) In the later use process, the hook is the weak point of the structure, and it will start to corrode from the hook, which will further cause structural reinforcement Corrosion is not conducive to the durability of the pipe gallery structure; (4) Sometimes it cannot be hoisted underground due to the limited terrain, and it is difficult to assemble it manually, so it needs to be improved
