Problems solved by technology

[0002] At present, the building structures at home and abroad are mainly constructed by using masonry, cement, sandbags and wooden boards, or directly poured by foaming materials. However, the walls of some building structures such as bridges, mines, and tunnels, As time goes by, it is subject to dynamic pressure changes and is prone to cracking. Once cracks are formed, it will affect the safety and firmness of the building structure.
In order to ensure the long-term safe service of the building, it is necessary to pour multiple times and deal with the cracks in the wall, which is time-consuming and expensive

Embodiment 1

[0034] A building self-repair system includes repair pipes 6 filled with adhesive distributed inside the building structure, and the repair pipes 6 are brittle pipes.

[0035] Preferably, the repair pipe 6 is a pipe structure with two parallel pipes, the repair pipe 6 is a double-hole pipe, and two-component chemical adhesives are respectively poured into the repair pipes. The two-component chemical adhesive is a flame-retardant polyurethane grouting material and its catalyst. The material of the repairing pipe 6 is glass or ceramics, and the wall thickness is 1mm; preferably, the repairing pipe 6 can be arranged in a straight line or in a continuous U-shape.

[0036] Preferably, a main slurry delivery pipe 2 communicating with the repair pipe is distributed inside the building structure. The main slurry delivery pipe 2 is a double-pipe parallel pipeline structure, and catalysts and grouting materials are respectively injected in the two pipelines; preferably, the main slurry...

Embodiment 2

[0039] A construction method of a building self-repair system, comprising the following steps:

[0040] (1) Two main slurry pipes 2 are installed on the left and right sides of the building wall structure, and the distance from the walls on both sides is 200mm-600mm;

[0041] (2) Open an air hole 4 on the upper part of each pipe of the main grouting pipe 2 to discharge the air in the pipe, and open a grout inlet 3 at the lower part of the air hole. After the grouting is completed, the grout inlet 3 and the air hole 4 must be closed;

[0042] (3) Set a group of continuous U-shaped or several straight double-hole repair pipes 6 between the two main slurry delivery pipes 2, connect the double-hole repair pipes 6 with the main slurry delivery pipes 2 on the left and right sides, and repair the pipes 6 The distance between each other is 100mm-400mm;

[0043] (4) Build a building wall, the distance between the building wall and the main slurry pipe 2 is 200mm-600mm;

[0044] (5) ...

Embodiment 3

[0045] Embodiment 3 Application of the self-repairing system of the present invention on the structure of the closed wall of the mine

[0046] The repair pipes used in this embodiment are several linear glass pipes, the closed filling material used is foamed concrete, and the two-component adhesive used is flame-retardant polyurethane grouting material and its catalyst.

[0047] Two main slurry delivery pipes 2 are respectively installed on the left and right sides of the position where the airtight wall needs to be set, and the distance from the roadway walls on both sides is 200mm-600mm, and an air hole 4 is opened on each pipeline upper part of the main slurry delivery pipeline 2. In order to discharge the air in the pipeline, a slurry inlet 3 is opened at the lower part of the air hole, and a number of linear double-hole quartz glass repair pipes 6 are arranged between the front and rear main slurry pipes 2, and the repair pipes 6 are connected to the main delivery pipes on...

Abstract

The invention belongs to the technical field of building construction structures and particularly relates to a building self-repair system and a constructing method and application thereof; the building self-repair system is characterized in that a repair network injected with bi-component adhesive is distributed in a building structure, repair pipes break under the action of stress when the building structure cracks, the adhesive inside is released, and a wall is repaired quickly. The building self-repair system has the advantages of high efficiency, high speed and self-repair capacity.

Description

technical field [0001] The invention belongs to the technical field of building construction structures, and in particular relates to a building self-repair system and its construction method and application. Background technique [0002] At present, the building structures at home and abroad are mainly constructed by using masonry, cement, sandbags and wooden boards, or directly poured by foaming materials. However, the walls of some building structures such as bridges, mines, and tunnels, With the passage of time, the dynamic pressure changes and it is easy to crack. Once the cracks are formed, it will affect the safety and firmness of the building structure. In order to ensure the long-term safe service of the building, it is necessary to pour multiple times and deal with the cracks generated in the wall, which is time-consuming and material-intensive. [0003] Therefore, a building self-repair system that can be widely used in various building structures such as bridges...
