Problems solved by technology

[0002] The traditional soil nailing wall slope protection construction drilling equipment uses a crawler-type screw bolt drill. During the drilling process in soft soil layers, the construction speed is slow, the dust is large and the construction cost is high. Often, the foundation pit cannot be closed in time after excavation. The soil around the foundation pit is prone to cracking or even slipping after rain
Therefore, in the construction process of soil nailing wall protection for slopes in soft soil layers, the traditional screw bolt drilling rig has certain limitations in terms of construction speed, environmental protection and cost.

Abstract

The invention relates to a soft soil layer foundation pit side slope anchor rod drilling device, which comprises a mounting bracket arranged on the breaking hammer head of a hydraulic breaker, a first mounting plate arranged at the bottom of the mounting bracket, and a The steel pipe used for drilling on the board; the present invention forms a drill rod by installing a steel pipe on the breaking hammer head of a hydraulic breaker, and uses the hydraulic function of the breaking hammer to push the steel pipe into the soil layer and form a hole after reaching the designed depth. Suitable for soft soil slopes.

Description

technical field [0001] The invention relates to the field of building construction equipment, in particular to a soft soil foundation pit side slope bolt drilling device. Background technique [0002] The traditional soil nailing wall slope protection construction drilling equipment uses a crawler-type screw bolt drill. During the drilling process in soft soil layers, the construction speed is slow, the dust is large and the construction cost is high. Often, the foundation pit cannot be closed in time after excavation. Cracking or even slipping of the soil around the foundation pit is prone to occur after rain. Therefore, in the construction process of soil nailing wall protection for slopes in soft soil layers, the traditional screw bolt drilling rig has certain limitations in terms of construction speed, environmental protection and cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a soft soil layer founda...
