It is understood that there are many people in Qiongzhong house foundation backfill sinking grouting construction treatment operation is not very understood, this article is a related article introduction, welcome to read.
Preparation: 1. Determine the construction nature and requirements of the backfill sinking grouting construction.
2.Formulate the construction plan, including the construction process, construction process and construction safety measures.
3.Check the condition of the foundation at the construction site to ensure that the foundation meets the construction requirements.
4.Prepare the materials and equipment required for construction, including grouting materials, grouting equipment, testing instruments, etc.
Construction technology: 1. Clean up the construction site to ensure that the construction area is clean and tidy.
2.Ground treatment is carried out, including excavation of the layer of soil to be filled, removal of debris and loose soil from the surface of the foundation.
