Due to the fact that more and more family members have recently begun to pay attention to the construction steps of foundation sinking grouting reinforcement, this article is about its relevant information, hurry up and save it for collection.
Ground sinking grouting reinforcement is a common method of reinforcement of civil engineering structures, which is suitable for various civil engineering structures that need to be reinforced, such as building foundations, roadbeds, bridges, etc. The following introduces the construction steps of foundation sinking grouting reinforcement from many aspects such as concept, preliminary investigation and construction.
1. Concept: Foundation sinking grouting reinforcement is to repair and strengthen the foundation by injecting specific materials to solve the structural problems caused by foundation subsidence or instability. The grouting material is usually concrete, polymer or polyurethane, etc., which has high strength and stability.
2.Preliminary investigation: Before carrying out the foundation sinking grouting reinforcement construction, detailed preliminary investigation work is required. This includes measuring and assessing the extent of foundation subsidence, its causes, and the extent of its impact. It is also necessary to investigate the soil type, groundwater level, geological conditions, etc., to determine the appropriate grouting material and construction plan.
3.Pile foundation treatment: If it is found that there is a large instability or liquefaction risk in the lower part of the foundation during the survey, it is necessary to use the pile foundation for reinforcement. Pile foundations can be constructed by piling or pouring to increase the stability and bearing capacity of the foundation.
4.Grouting hole construction: according to the design requirements, drilling in the lower part of the foundation, generally using a drilling machine. The location, spacing, and depth of the holes vary depending on the project.
5.Grouting material preparation: According to the engineering needs, select the appropriate grouting material, usually a mixture, whose fluidity and setting time can be controlled as needed. At the construction site, it is necessary to prepare and mix the materials according to the instructions for the use of the materials.
6.Grouting construction: The prepared grouting material is injected into the pre-drilled grouting hole through the pipeline or pumping equipment. Grouting construction needs to be selected according to the design requirements of the construction point and the control of the construction pressure to ensure that the grouting material fully fills the pores and achieves the expected reinforcement effect.
7.Settlement observation: After the grouting construction is completed, the settlement observation of the reinforcement area needs to be carried out to evaluate the reinforcement effect. Observations can be made over a period of time, based on which the quality of construction is assessed, and subsequent repair or reinforcement measures can be carried out if necessary.
Ground subsidence grouting reinforcement is an effective method for reinforcing civil engineering structures, which can realize the repair and reinforcement of foundation subsidence problems and ensure the safety and stability of civil engineering structures through conceptual understanding, preliminary investigation, pile foundation treatment, grouting hole construction, grouting material preparation, grouting construction and settlement observation.
