Abstract

The invention relates to a method for reinforcing soft soil foundation in a cushion layer replacement mode. The method for reinforcing the soft soil foundation in the cushion layer replacement mode comprises the steps that (1) a position to be excavated is marked out in the soft soil foundation and an excavator is arranged at the position to be excavated; (2) a pit slot is excavated through the excavator and a soil layer and surface dust are cleaned up; (3) filling-replacement filling materials are prepared; (4) the filling-replacement filling materials are filled in the pit slot and are paved flatly and smoothly; (5) a vibration roller is used for grinding the pit slot filled with the filled filling-replacement filling materials; (6) the surface of the filling-replacement filling materials is kept being wet after being grinded, maintenance is started after the filling-replacement filling materials are finally coagulated, and the maintenance time is 30 to 40 days. Compared with the prior art, the method for reinforcing the soft soil foundation in the cushion layer replacement mode enables the soft soil foundation to be high in reinforcing quality, high in intensity, convenient to construct, low in cost, and significant in economical benefit.

Description

technical field

[0001] The invention relates to a method for strengthening soft ground, in particular to a method for strengthening soft ground by replacing cushion layers. Background technique

[0002] With the rapid development of power grid construction, the basic design of transmission lines is related to the safe operation of the line, and more importantly, the investment and comprehensive benefits of the project. At present, the commonly used foundation types are: ① slab foundation; ② bored pile foundation. Among them, the straight column foundation is generally used in areas with good geological conditions, while the cast-in-situ pile foundation is generally used in unfavorable geological areas such as river ponds and soft soils.

[0003] In the area of ​​soft soil foundation, the design of the tower foundation in the soft soil foundation area has its particularity because the design of the tower foundation should not only meet the design requirements of the general ...
