Construction method for protecting slope of soil-nail wall and special equipment for protecting slope of soil-nail wall

Abstract

The invention discloses a construction method for protecting a slope of a soil-nail wall and special equipment for protecting the slope of the soil-nail wall. After the method and the special equipment of the invention are adopted, the equipment can be operated in the position at which a soil excavating machinery can pass through because a drill hole and a blow-in bolter is linked with an excavator or an excavator type platform. The equipment has low requirements on the site and can finish the slop protection working under extremely serious working conditions. When the lower part in a base pit of the construction site has no working scene, the equipment can be stopped at the upper slope opening and constructs downwards by adjusting large and small arms of the excavator, and the excavator can construct in the base pit from bottom to top vice versa. When a vertical anchor rod is required for construction, the equipment has no any difficulty and extremely high efficiency. The construction working method and the special equipment of the invention can solve the difficulty of working surface competition with the excavator machinery, the base pit working surface exposed due to soil excavation can be reinforced and processed in the shortest time, and the working efficiency can be greatly enhanced.

Description

Technical field [0001] The invention relates to a slope protection construction method and related equipment, in particular to a soil nail wall slope protection construction operation method. Background technique [0002] The bolter is also called an anchor drill in some places, and it is a drilling tool for bolt support in coal mine roadways. It has outstanding advantages in improving the supporting effect, reducing supporting costs, accelerating the speed of roadway formation, reducing auxiliary transportation, reducing labor intensity, and increasing the utilization rate of roadway section. The bolting rig is the key equipment for bolt support. It affects the quality of bolt support-the orientation, depth, and hole diameter accuracy of the bolt hole, and the quality of bolt installation, as well as the personal safety and labor of the operator. Strength and working conditions, etc. According to the structure, it is divided into single type and drill carriage type; according ...

AI Technical Summary

Problems solved by technology

However, the existing soil nail wall anchor construction machinery basically adopts the construction method combining manual and mechanical from the hole forming anchor to the driving anchor, and its disadvantages are obvious: labor intensity is large, and two Different Construction Machines: Electric Drilling Machines and Pneumatic Driving Hammers

More importantly, these special hole-forming equipment need a relatively spacious or ideal working surface, and the transportation and walking of these special equipment require ideal roads, which are precisely what the construction site is difficult to provide

Sometimes there is a conflict with the working surface of the excavator, which causes the equipment to fail to work when the excavator is working, which affects the work efficiency of the entire project

At the same time, the pneumatic bolter also has many disadvantages such as difficulty in driving in, high labor intensity, low production efficiency, and hidden dangers of unsafe construction personnel.
