Description

Technical Field

[0001] This utility model relates to the field of geotechnical engineering construction technology, specifically a protective device for geotechnical engineering construction. Background Technology

[0002] In geotechnical engineering construction, it is often necessary to blast rock slopes before mining and excavation. During mining and excavation, broken rock fragments can easily fall from the rock slope. Therefore, it is necessary to install a protective net structure at the bottom of the rock slope to block falling rock fragments and prevent them from injuring construction workers.

[0003] Existing protective devices for geotechnical engineering construction rely on support rods that are merely fixed to the ground. This makes the support rods and the protective netting susceptible to damage from falling rocks, causing them to tilt and loosen the netting, thus reducing its protective effectiveness. Furthermore, the lack of an effective connection between the lower edge of the netting and the base of the support rod allows fallen rocks to leak out at the point where the lower edge of the netting contacts the ground, further diminishing the protective effect. Utility Model Content

[0004] The technical problem this utility model aims to solve is to overcome existing defects and provide a protective device for geotechnical engineering construction. Through the installation of a diagonal brace, base, fixing ring, inclined steel cable, steel cable anchor, hinge seat, and base anchor, the bottom of the diagonal brace is fixed to the rock face via the base anchor, and the upper part of the diagonal brace is fixedly connected to the rock face via the inclined steel cable and steel cable anchor. This secure connection ensures that the diagonal brace and protective net are not damaged by falling rocks, and prevents the diagonal brace from tilting, effectively solving the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective device for geotechnical engineering construction, comprising a base and a diagonal brace, wherein a pressure plate is provided on the upper side of the base, a soil-entry rib is welded to the lower side of the base, a mesh holder is provided on the diagonal brace, a fixing ring is welded to the diagonal brace, a diagonal steel cable is connected to the fixing ring, an expansion bolt is provided on the base, a hinge seat is provided on the upper side of the base, and a base anchor rod is connected to the hinge seat.

[0006] Furthermore, the wire mesh holder includes a cover plate, a fixing seat, a wire threading hole, and a fixing bolt, wherein the cover plate and the fixing seat are connected by the fixing bolt.

[0007] Furthermore, a cable anchor is provided at one end of the inclined steel cable, and a protective net is installed on the inclined support rod through the net seat.

[0008] Furthermore, the protective net is connected to the fixed base via the cover plate and the fixing bolts, the fixed base is welded to the diagonal brace, and the lower end of the diagonal brace is welded to the base.

[0009] Furthermore, the steel cable anchor is connected to the inclined steel cable via a wire rope buckle, and the inclined steel cable is connected to the fixing ring via a wire rope buckle.

[0010] Furthermore, the lower edge of the protective net is connected to the base via the pressure plate, and the pressure plate is connected to the base via bolts.

[0011] Furthermore, the hinge seat is welded to the base, and the hinge seat is rotatably connected to the base anchor rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the setting of diagonal bracing rods, bases, fixing rings, diagonal steel cables, steel cable anchors, hinge seats, and base anchors, ensures that the bottom of the diagonal bracing rod is fixed to the rocky mountain through the base anchors, and the upper part of the diagonal bracing rod is fixedly connected to the rocky mountain through the diagonal steel cables and steel cable anchors. This ensures that the diagonal bracing rod and the protective net are not damaged when impacted by falling rocks, and that the diagonal bracing rod will not tilt.

[0014] 2. This utility model uses a pressure plate and a base to press and fix the lower edge of the protective net onto the base, preventing stones from leaking out from the gap between the lower edge of the protective net and the base when they fall, thus improving the protective effect.

The other end of the inclined steel cable 5 is fixed to the rocky hillside using steel cable anchors 4, so that the diagonal brace 11 and the protective net 8 are effectively fixed, ensuring that the protective net 8 and the diagonal brace 11 effectively protect against falling rocks and prevent the diagonal brace 11 from tilting under the huge impact force of falling rocks, thus ensuring the protective effect. The lower edge of the protective net 8 can be fixed to the base 1 using pressure plates 9, so that the gap between the lower edge of the protective net 8 and the base 1 is sealed, preventing falling rocks from leaking out from the gap between the lower edge of the protective net 8 and the base 1, thus ensuring the protective effect.
