Abstract

The invention discloses a reinforcing and strengthening processing method of chemical grout, a injected body is slightly divided into a plurality of injected rock surfaces through being layered and segmented, then holes are drilled on the injected rock surfaces, the grout injecting pressure and the grout injecting speed of the grout injection are controlled, and the grout injecting time is sufficient, the surface tension whose initial viscosity is 2.0 m Pa.s-15.0 mPa.s and is less than the surface tension of water is used, the surface tension is not less than 0.050 m N / m at 20 DEG C, and epoxide resin grout materials with 1-16 degrees contact angles and the like are used, thereby epoxide resin slurry uniformly filters into a hole and a minuteness crack of the injected body, the gluing of gelatinization matter is good, the properties of the injected body is integrally improved, the strength of the injected body and the like are greatly improved, the over-high engineering cost is avoided, and the manufacturing cost is saved through controlling the infiltration range.

Description

technical field

[0001] The invention relates to the field of engineering construction reinforcement, in particular to the technical field of chemical grouting reinforcement and reinforcement treatment. Background technique

[0002] Engineering foundation and engineering component reinforcement problems are often encountered in engineering construction, especially in hydropower development. When hydropower development and construction of dams, many dam foundations have poor geological conditions. Often a good dam site has poor geological phenomena, among which weak and low-permeability strata are the most difficult geological phenomena encountered in the process of dam construction. The technical problems to be solved have great, even world-class technical difficulties. Usually, when the dam foundation encounters complex geological conditions, the method of cement grouting and excavation and replacement can be used to deal with it; when more complex geological phenomena, suc...
