In summer, there are heavy rains and extreme weather, the amount of rainwater is large, the soil water content is high, and the stability of the soil will increase. The foundation of the building is easy to be soaked by rain for a long time, and the soil may dissolve and lead to collapse.

First, the impact of heavy rain on the foundation

There is a real possibility that heavy rain could cause the tilt settlement to collapse. Specifically, the impact of heavy rain on the foundation is mainly reflected in the following aspects:

1. Softening of the foundation: rainwater infiltration into the ground may cause the foundation soil to become soft and reduce its carrying capacity. This makes the foundation of the building unstable and increases the risk of settlement and tilt.

2, soil saturation: A large amount of precipitation may make the soil saturated, reducing the friction and stability of the soil. In the saturated state, the effective stress between soil particles decreases, resulting in a significant decrease in soil carrying capacity. When the soil contains fine grained materials such as clay, its load bearing capacity decreases more significantly after saturation.

3, the rise of the groundwater level: continuous precipitation may raise the groundwater level, increase the buoyancy effect of groundwater on the foundation of the building, and have an adverse impact on the basement, underground pipes and other structures.

4, water erosion: the flow formed by rainfall may wash away the foundation and slope, resulting in soil erosion and loss, weakening the stability of the geological structure.

tilt settlement Method

tilt settlement is a serious issue that needs to be addressed accordingly. Here are some common tilt settlement treatments:

1. Strengthen the foundation:

① Foundation settlement repair technology: Tongcheng Soft Foundation uses new special composite materials to be injected into the depth of the ground and consolidated with the soil to form a new composite foundation, improve the strength of the soil and the bearing capacity of the foundation, and realize the tilting and flexible lifting of the main body of the building. The technology is suitable for complex geological conditions, has high economic benefit, simple and convenient process, and short construction period.

Compared with the traditional foundation reinforcement method that needs to destroy the building structure, the process is complex and time-consuming, Tongcheng soft foundation trenchless restoration technology, the use of miniaturized equipment, micro-hole treatment, no relocation, no demolition, does not affect the production and life, can achieve deep soil reinforcement of buildings, industrial buildings and other building foundations, flexible lifting, so that the building can restore the balance state.

② Reinforced pile: By driving reinforced piles into the foundation, such as reinforced concrete piles, cast-in-place piles, etc., to improve the bearing capacity of the foundation.

2. Fill soil reinforcement: Fill the area of tilt settlement with an appropriate amount of soil to achieve the purpose of increasing the bearing capacity of the foundation. The filled soil should meet certain thickness and quality requirements.

3, install support structure: install support structure in the lower part of the foundation, such as steel support, concrete support, etc., to increase the strength and stability of the foundation.

4. Redesign the building: If tilt settlement is severe and cannot be solved by, for example, strengthening the foundation, it may be necessary to redesign the building to adopt a more stable structural form.

5, drainage treatment: ensure that the drainage system around the building foundation is normal, such as drainage ditches, collection Wells, etc., reduce water penetration into the foundation, ensure that the rain can be discharged in time, avoid the foundation being soaked, prevent the foundation from further softening and sinking.

6, regular monitoring and maintenance: After the completion of foundation reinforcement and repair, it is necessary to regularly monitor the foundation and the building to observe whether the foundation continues to sink and the stability of the building. Strengthen the maintenance and management of buildings, discover and deal with potential safety hazards in a timely manner, and ensure the long-term safe use of buildings.

7. Professional consultation: Dealing with the deviation of the main body of the building caused by the foundation settlement requires professional knowledge and experience. Therefore, it is recommended to consult a professional engineer, architect or relevant institution for accurate advice and solutions.
