The following article on construction experience: pressure grouting reinforcement common problems are quite good, by reading the following article, you can have a more in-depth understanding of this.
Grouting reinforcement is a commonly used method of structural reinforcement in civil engineering, which is suitable for all kinds of buildings and structures, especially those where there are cracks, deformations, or insufficient strength. During the construction process, there are often some common problems that need to be paid attention to and solved in time to ensure the reinforcement effect and project quality.
1. Concept: Pressure grouting reinforcement refers to the engineering technology of enhancing the bearing capacity and stability of soil or concrete by injecting cement slurry or other specific slurry into existing holes or excavated caverns. Grouting reinforcement can fill and reinforce soil voids, improving the overall strength and stability of the structure.
Second, the preliminary survey:
Before the pressure grouting reinforcement construction can be carried out, detailed preliminary investigation work is required, including a comprehensive investigation and assessment of the disease and damage of the structure, and the location and scope of the reinforcement need to be determined. At the same time, it is also necessary to determine the construction plan and technical parameters of grouting reinforcement to ensure the smooth progress of construction.
3. Construction:
1. Hole cleaning: Before grouting reinforcement, it is necessary to clean up the debris and cement mortar in the hole to ensure that the grouting grout can fully fill the hole.
2.Grouting equipment: select suitable grouting equipment and slurry, and debug and set up according to the construction requirements.
3.Construction process control: control the pressure, speed and amount of grouting, adjust the parameters in time to ensure that the grouting effect meets expectations.
4.Quality inspection: After the construction is completed, the quality inspection of the reinforced structure is required to ensure that the reinforcement effect meets the design requirements.
Common problems of pressure grouting reinforcement include uneven grouting, slurry loss, pore blockage, etc., and it is necessary to pay attention to construction quality and on-site management during the construction process, find and solve problems in time, and ensure the reinforcement effect and project quality.
