Integrated construction device and method

Abstract

The invention relates to an integrated construction device and an integrated construction method. The integrated construction device is used for repairing and protecting a damaged or degraded concretesurface layer and comprises a steeping cavity (11), negative pressure equipment (9) and a liquid storage tank (8); the steeping cavity (11) comprises a cover plate (6) and a cushion layer (4), and the cover plate (6), the cushion layer (4) and the concrete surface layer (10) are used for jointly enclosing a sealing cavity used for being filled with steeping liquid (110); the negative pressure equipment (9) is connected with the steeping cavity (11) and used for providing negative pressure to the sealing cavity; and the liquid storage tank (8) is connected with the steeping cavity (11) and used for storing the steeping liquid (110). According to the integrated construction device and the integrated construction method, when the concrete surface layer is repaired, a protecting layer is formed on the concrete surface at the same time, so that repairing and protecting of the concrete surface layer are simultaneously realized through one-time construction.

Description

technical field [0001] The present invention relates to an integrated construction device and an integrated construction method, in particular to an integrated construction device and a corresponding method for simultaneously realizing concrete surface repair and protection through vacuum polymer impregnation on the surface of damaged or deteriorated concrete buildings . Background technique [0002] The climatic conditions in western my country are very severe and harsh: hot summer, dry and cold winter, large temperature difference, high wind speed, low relative humidity, etc., which pose a great threat to the durability of local concrete structures. According to the field investigation results of relevant scholars on concrete buildings in western my country, cracks, surface erosion and steel corrosion can be seen everywhere in the built concrete channels, bridges, roads, etc., which seriously affect the safety and service life of structures, and bring great impact to our c...

AI Technical Summary

Problems solved by technology

[0004] 1. The impregnation solution in the flexible negative pressure impregnation chamber has no residue and no residual monomer, so the protection of the concrete surface is not ideal

The flexible negative pressure impregnation process only plays a certain role in repairing the surface defects of concrete buildings, and it cannot achieve the ideal effect of "repairing the old as new" for the surface with serious damage and erosion; after the impregnation is completed, follow-up wiping is required Flat, multiple coating and other processes to improve the appearance and achieve protection;

[0005] 2. The construction process is cumbersome

Before impregnation, it is necessary to lay and fix the liner, and the liner needs to be removed after the impregnation solution is cured. The process is cumbersome, and the construction on the vertical surface or the slope with a large slope is especially inconvenient;

[0006] 3. The impregnation efficiency is low, and the area in the impregnation cavity cannot be 100% impregnated and repaired

For large-area construction, because the film is close to the repaired surface during impregnation, it is difficult to control the flow path of the impregnating liquid in the vacuum chamber, and it is easy to form impregnation blind spots in the surrounding area, and the impregnation area only accounts for about 90% of the area covered by the impregnation chamber. , the remaining 10% of the area can only be repaired by manual smearing, which will affect the construction progress and repair effect;

[0007] 4. The vacuum degree in the impregnation chamber is low, and the repair effect on concrete is limited

The low vacuum in the impregnation chamber leads to low impregnation depth of the impregnating liquid in the concrete, so the repair and reinforcement of the concrete is limited; at the same time, the low vacuum makes it almost impossible to absorb the impregnating liquid into the cracks during facade construction
