grouting in soil stabilization The problem of subsidence can be solved in the following ways:

First, preventive measures

1. Control the quality of filling soil: choose good quality soil for backfilling, avoid the use of wet soil, organic soil and silt soil.

2. Uniform compaction: the fill is uniformly compacted, especially near the building, to ensure that there is no obvious fluctuation in the surface of each layer.

3. Control the construction speed: the backfill construction should avoid being too fast to prevent soil consolidation and affect the stability of the foundation.

4. Properly set drainage measures: During the backfill process, properly set drainage measures to prevent surface water from soaking the soil and affecting the stability of the foundation.

5. Reasonable selection of backfill materials: For areas with high groundwater level, materials with good water permeability can be selected for backfill, such as medium and coarse sand.

Second, post-sinking treatment measures

1. Geological Investigation and analysis:

① Geological survey is carried out to obtain geological information related to backfill collapse, including soil type and formation structure. Geological characteristics were analyzed to determine the physical and mechanical properties of soil and the possible causes of backfill collapse.

(2) Conduct site investigation of backfill collapse and record information such as location and type of subsidence or collapse point.

Measure the deformation of the surface or underground, and analyze the degree and trend of deformation.

(4) Analyze the influence of buildings or structures on backfill collapse.

2. Trenchless repair technology: The use of new materials, microhole injection, rapid consolidation of soft foundation backfill to form a new structure. In the process of filling and compaction, it can effectively strengthen the backfill and other soil layers, control the deformation of the foundation, and generate the lifting force to achieve the lifting effect.

Tongcheng soft base surface settlement repair technology is simple, strong operability, can adapt to a variety of complex construction environment, and lightweight equipment, easy to carry out work.

3. Strengthen monitoring: Install deformation monitoring equipment, regularly monitor the foundation, and timely deal with abnormal situations. Timely maintenance and repair of collapsed areas, filling of stable soil, and strengthening of plant structures.
