Caulking and jointing construction method for brick joints of tiles in tunnel

Abstract

The invention discloses a caulking and jointing construction method for brick joints of tiles in a tunnel. The caulking and jointing construction method is characterized in that a brick joint caulkingand jointing device is adopted to caulk or joint the brick joints of the tiles in the tunnel; the brick joint caulking and jointing device includes a caulking and jointing trolley capable of moving back and forth on the surface of a masonry structure and a storage hopper for storing filling mortar which is used for filling the brick joints; when caulking is actually performed, the steps of jointing device removal, storage hopper connection, filling mortar adding, being-in-place of a caulking trolley with a hopper and caulking are included; and when jointing is actually performed, the steps ofstorage hopper connection, filling mortar adding, being-in-place of a jointing trolley with a hopper and jointing are included. The caulking and jointing construction method has reasonable design, simple and convenient construction, high construction efficiency and good use effect, the movable brick joint caulking and jointing device is used for caulking or jointing the brick joints, the fillingmortar can be automatically fed into the treated brick joints, compaction and groove pressing forming can be performed on the filling mortar fed into the brick joints, and the quality of caulking andjointing can be ensured.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a method for filling and pointing joints between ceramic tiles in a tunnel. Background technique [0002] Brick joint refers to the gap between two adjacent masonry blocks, where the masonry blocks are bricks (referring to sintered bricks), stones, stone plates, ceramic tiles, mosaics, wood boards, glass boards, aluminum-plastic boards, etc. , multiple masonry blocks are built to form a masonry structure. Filling refers to filling the gap between two adjacent masonry blocks with caulking agent (also known as jointing agent, filling material, filling mortar, caulking mortar or jointing mortar). The gap is filled, and the actual gap filling only needs to be filled with the gap filler between two adjacent masonry blocks. Pointing refers to the use of jointing agent to fill the gap between two adjacent masonry blocks. Its function is to effectively make the ...

AI Technical Summary

Problems solved by technology

Among them, the first type of electric caulking machine and similar manual caulking equipment use the principle of electric screw grout feeding to continuously send the mortar in the storage bin from the grout outlet for caulking, so as to achieve the purpose of mortar caulking in brick joints. The machine has obvious effect on the grouting and filling of brick joints with a width of 5 mm to 10 mm. The mortar filling is relatively full, but the mortar is uneven and wavy after the electric joint filling machine fills the joints, and it still needs to be manually hooked in the later stage seam

The second type of electric caulking machine and similar manual caulking equipment use the principle of electric hose slurry feeding to continuously send the mortar in the storage bin through the slurry delivery hose from the slurry outlet for caulking. The machine has a width of 5 The grouting and filling of the brick joints with a thickness of mm to 10 mm has obvious effects, and the mortar filling is relatively full, but the mortar is still uneven and wavy after filling with the electric grout feeding machine, and manual pointing is still required in the later stage

The third type of electric caulking machine and similar manual caulking equipment use charging power to continuously send the mortar in the storage bin from the slurry outlet to fill the joints by using electric push rods to achieve the purpose of mortar joints between bricks. The machine has an obvious effect on the grouting and filling of brick joints with a width of 5 mm to 10 mm. The mortar filling is relatively full, but the mortar is uneven and wavy after the electric push rod joint filling machine is filled, and it still needs to be manually hooked in the later stage. seam

But all three have the following disadvantages: first, the fluidity of the grouting material is large, and it is easy to deform after grouting; second, the grouting is uneven and wavy, requiring manual pointing in the later stage; third, the grouting mortar is easy to If the brick joint overflows, it is easy to pollute the brick surface (that is, the surface of the masonry block or the surface of the masonry structure); fourth, when the brick joint is small, it is easy to produce a large amount of overflow mortar. Cause the mortar to flow down and fall; Fifth, due to the large fluidity of the mortar and the overflow of the mortar, the material waste of the caulking mortar is relatively large

Therefore, the existing electric jointing machines cannot meet the actual jointing needs, and all need manual jointing in the later stage

[0005] However, manual caulking or manual pointing requires construction personnel to use special caulking or pointing tools to manually fill and point brick joints inch by inch, which consumes a lot of labor; The density and depth of the joints are uneven, the quality of the joints is poor, the labor intensity of the workers is extremely high, the construction efficiency of the joints is low, and the manual filling and joints cannot meet the large-area filling Seam and pointing construction requirements

[0006] To sum up, the existing brick joint filling and pointing methods and the corresponding electric joint filling equipment have problems such as backward equipment, many hours of work, large material loss, and high labor intensity. Different methods and operating levels of users cause problems such as different depths of joint filling and pointing, different construction standards, and differences in work efficiency, which is time-consuming and labor-intensive, and the construction quality is poor

Especially for the construction of large-area brick joints, such as the brick joints of the tile face protection layer in long tunnels, the problems existing in the existing brick joint filling and pointing methods and the corresponding electric joint filling equipment are more prominent

Tile armor in the tunnel refers to the tile armor formed on the lower part of the side walls on the left and right sides of the tunnel. It is laid on the whole line in the tunnel, so the area of ​​the tile armor is very large. Therefore, the existing brick joint filling and pointing methods and the corresponding electric joint filling equipment are difficult to meet the construction needs
