This article is a related introduction to the construction and treatment specifications of high-pressure grouting reinforcement of foundations, and if you want to know more thorough friends, let's take a look at the following related introduction.
The construction treatment specification for high-pressure grouting reinforcement of foundation refers to a series of specifications and standards followed when using high-pressure grouting technology for reinforcement treatment in foundation engineering, aiming to ensure the quality and safety of the project. High-pressure grouting reinforcement of foundation is an effective foundation treatment method, which can improve the bearing capacity and stability of the foundation and prolong the service life of the foundation.
The relevant characteristics and reinforcement methods are as follows:
1. High-pressure grouting is a soil reinforcement method without vibration and excavation and filling, which can effectively strengthen weak soil layers such as loose soil, fill, and soft soil, and improve the bearing capacity and seismic capacity of the foundation.
2.The high-pressure grouting reinforcement construction treatment specification requires that the construction personnel must have the corresponding professional skills and certificates to ensure the quality and safety of the construction.
3.The construction treatment specification for high-pressure grouting reinforcement of the foundation requires that a detailed investigation and analysis of the foundation be carried out before construction, and the construction plan and grouting hole location should be determined.
4.The grouting material is generally cement slurry, bentonite slurry or polymer slurry, and the grouting material is injected into the foundation through a high-pressure pump to fill the soil gap and form a solid soil slurry.
5.The layout of the grouting holes should be uniform and dense, and the hole diameter and hole spacing should meet the requirements of the specification to ensure that the grouting effect is uniform and sufficient.
6.After high-pressure grouting, quality testing should be carried out, including parameters such as pressure in the grouting hole, grouting concentration, slump, etc., to ensure that the foundation reinforcement effect meets the design requirements.
The construction treatment specification of high-pressure grouting reinforcement of foundation is an important foundation treatment method, which has high effect and reliability, can effectively improve the bearing capacity and stability of the foundation, and prolong the service life of the foundation. In the actual construction, the construction personnel should operate in strict accordance with the requirements of the specification to ensure the quality and safety of the project.
