A kind of method for hanging safety belt for underground continuous wall

Abstract

The invention discloses a safety belt hanging method for an underground continuous wall. The safety belt hanging bracket arranged on the surrounding wall of the foundation pit under construction is used to hang the safety belt worn by the construction personnel; The wall includes an underground diaphragm wall and a water retaining wall arranged on the underground diaphragm wall, and the safety belt hanging bracket includes a safety rope connected with the safety belt, a mobile bracket, a safety rope winding mechanism, a safety rope anti-reverse mechanism and a safety rope guiding mechanism; When the safety belt is hung, the steps include: 1. The construction platform is erected; 2. The safety belt hanging bracket is moved into place; 3. The safety belt is hung. The method of the present invention is simple, the design is reasonable, and the use effect is good. The seat belt hanging bracket that can be easily moved and firmly fixed can be used to provide a flexible, safe and reliable seat belt hanging point, which can effectively meet the requirements of underground continuous operation. Safety belt hanging requirements during large-area manual chiseling operations to ensure the safety and reliability of the construction process.

Description

technical field [0001] The invention belongs to the technical field of underground diaphragm wall construction, and in particular relates to a safety belt hanging method for an underground diaphragm wall. Background technique [0002] Diaphragm wall (also known as underground diaphragm wall) is a long and narrow deep groove excavated along the peripheral axis of the deep excavation project under the condition of mud retaining wall on the ground, and steel bars are hung in the groove after cleaning the groove Cage, and then use the conduit method to pour underwater concrete to build a unit trough section; in this way, a continuous reinforced concrete wall is built underground as a water interception, seepage prevention, load-bearing, and water retaining structure. The underground diaphragm wall belongs to an advanced construction method, which utilizes the outer wall of the same retaining wall of the underground space structure as the support of the deep foundation pit, and c...

AI Technical Summary

Problems solved by technology

Especially when the excavation area on the underground diaphragm wall of the foundation pit of the subway station is large, for example, when the underground diaphragm wall with a height of 9.3 meters and a length of 76 meters is manually excavated, since the height of the excavation area is 9.3 meters And its length is 76 meters, the chiseling area is very large, frequent high-altitude operations will inevitably cause great safety hazards, and bring certain difficulties to safety management
