If you are in the industry, you are generally clear about the construction and treatment operation of grouting reinforcement of soft soil foundation, but for ordinary people, you generally know less about it, and the relevant content is introduced below.
The construction treatment operation of grouting reinforcement of soft soil foundation is a common method for reinforcing soft foundation. In the construction process, it is necessary to select appropriate grouting materials according to the foundation conditions, and increase the bearing capacity and stability of the foundation through grouting reinforcement.
The steps of the soft soil foundation grouting reinforcement construction treatment operation comprise:
1. Foundation survey: determine the nature and strength of the soft soil foundation through foundation survey, and provide data support for subsequent construction.
2.Design scheme: According to the foundation survey results and engineering requirements, design the grouting reinforcement scheme, including the selection of grouting materials, the location and depth of grouting holes, etc.
3.Construction preparation: Prepare the required grouting equipment and materials to ensure the smooth progress of the construction process.
4.Drilling: Drilling holes in the foundation to form grouting holes so that the grouting material can fully penetrate into the foundation.
5.Grouting : Inject the selected grouting material into the foundation, and strictly control the grouting pressure and speed to ensure that the grouting penetrates evenly into the foundation.
6.Construction acceptance: Acceptance is carried out after the grouting is completed, and the reinforcement effect of the foundation is checked to see if it meets the design requirements to ensure the construction quality.
Features of grouting reinforcement of soft soil foundations include:
1. Simple construction: the grouting reinforcement construction process is relatively simple, and no large-scale earthwork is required, which reduces the project cost and construction period.
2.The effect is remarkable: the bearing capacity and stability of the soft soil foundation can be effectively increased through grouting reinforcement, and the overall performance of the foundation can be improved.
3.Wide range of application: grouting reinforcement of soft soil foundation is suitable for all kinds of soft foundations, including foundations with poor geological conditions such as silt and fine sand.
The methods of grouting and reinforcement of soft soil foundation mainly include: liquid spray method, drilling grouting method, fracturing method, etc. Each method has its own applicable foundation conditions and engineering requirements, and it is necessary to select the appropriate reinforcement method according to the specific situation. At the same time, it is necessary to pay attention to strictly control the quality and grouting pressure of grouting materials during the construction process to ensure the reinforcement effect.
