Construction method for repairing lateral displacement of retaining wall

Abstract

The invention relates to a construction method for repairing lateral displacement of a retaining wall. The method is characterized by comprising steps as follows: vertical borrow holes are vertically drilled in a soil body on the outer side of the wall back of the retaining wall, and dual-layer pressure balance hoses are inserted; transverse reaction steel plates and vertical reaction steel plates are arranged on the wall surface of the retaining wall, and transverse tie bar penetration holes and retaining wall ejection limiting grooves are formed in the transverse reaction steel plates and the vertical reaction steel plates respectively; a temporary reaction column is arranged on the outer side of the retaining wall, ejection devices are arranged between the reaction column and the reaction steel plates, and obliquely downward ejection force is applied to the retaining wall; transverse tie bars are arranged between the retaining wall and the soil body on the outer side of the wall back; obliquely downward ejection force and transverse pull force are applied to the retaining wall while vertical borrowing is performed; finally, oblique grouting holes are formed in the bottom of a foundation of the retaining wall, and solidified reinforcing bodies are formed through grouting. With the adoption of the method, the lateral displacement of the retaining wall can be repaired quickly, the integrity of the repaired retaining wall and the soil body on the outer side of the wall back can be enhanced, and the carrying capacity of the foundation of the retaining wall can also be improved.

Description

technical field [0001] The invention relates to a construction method for repairing the lateral displacement of a retaining wall, in particular to a construction method that can effectively prevent and control quality accidents in the process of repairing the displacement of the retaining wall, restore the lateral displacement of the retaining wall, and enhance the stability of the retaining wall Construction method for lateral displacement repair of retaining wall. The utility model belongs to the field of geotechnical engineering and is suitable for the lateral displacement repairing project of the retaining wall. Background technique [0002] Retaining wall is a common form of retaining structure in various engineering constructions, and has been widely used in highways, railways, port engineering, construction engineering and other fields. After the retaining wall is built, it mainly bears the loads such as its own weight and the earth pressure on the outside of the wal...

AI Technical Summary

Problems solved by technology

Although the structure takes into account the restoration of the lateral inclination of the retaining wall, the soil behind the wall needs to be excavated, and the construction work area is large; the reinforcement body needs to be re-arranged, which is easy to cause waste of the reinforcement body; The soil behind the wall is prone to stability problems, and the construction work is difficult
