Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039] refer to figure 1 , is pebble stratum soil nail drilling equipment disclosed by the present invention, comprises water drilling rig 1, and output shaft 2 is connected with transmission on water drilling rig 1, and drill rod 3 is screwed on output shaft 2, and drill rod 3 is multi-section, each drill Rod 2-4m, thereby can select the drilling rod 3 of different lengths according to different drilling depths. The adjacent drill rods 3 are threaded. One end of the drill rod 3 away from the water drilling rig 1 is screwed with a drill bit 4 .

[0040] refer to figure 2 , the drill bit 4 comprises a rod body 41, a plurality of drill teeth 42 fixed on the peripheral surface of the rod body 41 at uniform intervals and a drilling portion 43 fixed at the end of the rod body 41, the drill teeth 42 are at least three, and the drilling portion 43 It is U-shape...

Abstract

The invention relates to cobble stratum soil nail drilling equipment and relates to the technical field of soil nail construction. The cobble stratum soil nail drilling equipment comprises a water drilling machine, multiple sections of drills rod detachably connected to the water drilling machine and a drill bit connected to the drill rod; adjacent drill rods are in threaded connection; the drillbit comprises a rod body, multiple drilling teeth fixedly arranged on the circumferential surface of the rod body and a drilling portion fixedly arranged at the end part of the rod body; the drillingportion is in a U shape; and one end, far away from the drilling portion, of the rod body is connected with the drill rods. Cobble blocks are extruded to the periphery through the drill bit to form holes, and the cobble stratum soil nail drilling equipment has the advantages of simple structure, low cost, high construction efficiency and easiness in hole formation in the cobble layer.

Description

technical field [0001] The invention relates to the technical field of soil nailing construction, in particular to soil nailing drilling equipment for pebble formations. Background technique [0002] Soil Nail Wall (Soil Nail Wall) is an in-situ soil reinforcement technology. The side slope of the foundation pit is reinforced by soil nails made of steel bars, and a reinforcement mesh is laid on the surface of the side slope, and then a layer of concrete surface layer is sprayed and the earthwork side slope is combined with the side slope reinforcement support construction method. Its structure is a complex formed by the reinforcement rods (i.e. soil nails or anchors) set in the slope and the surrounding soil firmly bonded, and a support structure similar to a gravity retaining wall formed by the surface layer. [0003] At present, the following three methods are generally used for soil nailing wall drilling: [0004] 1. Use a Luoyang shovel to form a hole, then insert a st...
