What is foundation reinforcement? Chengde foundation reinforcement refers to the lack of natural foundation, which can not meet the main points of foundation bearing capacity and deformation design, and the foundation needs manual treatment, that is, foundation reinforcement. Foundation reinforcement is a method to strengthen the foundation according to the requirements of the superstructure on the foundation, improve the bearing capacity of the foundation, ensure the stability of the foundation, reduce the settlement or uneven settlement of the superstructure, remove the loess collapsibility, and improve the anti-liquefaction ability.

Chengde foundation reinforcement method

1, Chengde grouting reinforcement method

Grouting reinforcement method is applicable to gravel soil, sand soil, clay, artificial filling and other foundation reinforcement. It is used for preventing seepage and plugging leakage. Improve the strength and deformation modulus of the foundation soil or control the formation settlement.

2. Root pile method

The root pile method is applicable to the restoration and addition of existing buildings on the foundation soil such as silt, silt soil, clay soil, gravel soil, artificial fill soil, and some reinforcement projects, such as the upgrading of ancient buildings and the crossing of underground railways.

3, Chengde anchor static pressure pile method

The anchor static pile method is applicable to the foundation soil such as silt, silty soil, sand soil and artificial filling soil.

4, Chengde increase the base area method

For the foundation with small bearing capacity difference, increase the base area, increase the contact area between the foundation and the foundation, reduce the soil stress, and achieve the purpose of strengthening the foundation.

5, high pressure jet grouting method

High pressure jet grouting method is applicable to silt, silt soil, viscous soil, gravel soil, artificial fill, gravel soil and other foundations.
