Loose rock fill slope anchor cable eccentric down-the-hole hammer full casing and pipe anchoring construction equipment

Abstract

The present invention relates to the technical field of anchor cable construction, and discloses construction equipment for anchoring anchor cables with eccentric down-the-hole hammers on loose rock-filled slopes, including scaffolding, concentric down-the-hole hammers, eccentric down-the-hole hammers, pull-out equipment and injection molding equipment. Slurry equipment, the scaffold has a workbench, the workbench is provided with a support frame, the support frame has a guide surface, and the support frame is equipped with a drilling rig; the concentric down-the-hole hammer is placed on the guide surface, and is driven by the drill rig to drill through the retaining wall; the eccentric down-the-hole The hammer is placed on the guide surface, driven by the drilling rig to drill into the slope to form an anchor cable hole, and the full casing is embedded in the anchor cable hole; the extraction device is fixed on the retaining wall of the slope, and the anchor cable hole The full casing is pulled out, and the grouting equipment is injected into the anchor cable hole where the anchor cable is placed; the eccentric down-the-hole hammer full casing and pipe anchoring construction equipment for the loose fill stone slope anchor cable has high rock breaking efficiency, good anchoring quality, The advantages of simple operation and low overall cost.

Description

technical field [0001] The patent of the present invention relates to the technical field of anchor cable construction, in particular, it relates to the construction equipment for anchor cable eccentric down-the-hole hammer complete casing and pipe anchoring on loose rock fill slopes. Background technique [0002] The following problems exist in the anchor cable drilling construction on the loose rock fill slope: 1), the crawler anchor cable drilling rig is heavy, and the ordinary scaffolding operation platform is difficult to meet the operation requirements; 2), the rock fill distribution is large and the block is large , High hardness, ordinary anchor cable drilling rigs have low hole-forming and rock-breaking efficiency, slow drilling speed, and high overall cost; 3) When the drilling rig is drilling, the loose fill soil on the loose rock-fill slope is prone to collapse, resulting in hole formation Difficulty, which greatly affects the quality of hole formation and anchor...
