Abstract
The utility model relates to an anchor chock integrated tube type anchorage cable, which is used for rock and soil engineering, such as a side slope, a road cutting, a mountain, a tunnel, an underground chamber, etc., and is especially suitable for strengthening and supporting loose and broken and weathered rock (soil) bodies. The utility model is composed of an anchorage cable body made of a full-length threaded steel pipe or a seamless steel pipe, a grouting section, a sealed anchoring section, a free section, a grout jetting hole, etc. Since a sealing anchoring volume is arranged outside the sealed anchoring section, which effectively solves the problem of anchoring and strengthening sealing holes, sealing and anchoring are slickly combined simultaneously, so as to achieve the integration of anchoring and sealing. Moreover, rock (soil) bodies are grouted and strengthened with high pressure via an external port of the anchorage cable connected with a high-pressure grouting pump, so as to achieve the integration of anchoring and pouring and enlarge the working range and the reliability of a preload stress anchorage cable reinforcing in incompact and weathered rock (soil) bodies. The utility model has the advantages of low cost and simple structure.
Description
The utility model is applicable to side slope, cutting, massif, large cross-section tunnel, underground chamber, underground power house, intersection, tunnel isolith geotechnique Cheng Jiagu and supporting, is particularly useful for raveling, the reinforcing of the decomposed rock soil body.
At present, prestressed anchorage technology mainly adopts steel hinge rope or solid reinforcing bar to make anchor cable, complex structure, cost height, need be constructed with special tensioning equipment, and problem such as exist prestressing force easily to lose, consolidation effect is unreliable, in the engineerings such as China's Beijing-Kowloon Railway Ganzhou section massif slope reinforcement, a lot of prestress anchoraging barricade collapse accidents once took place, and caused the tremendous economic loss.Though now the slurry injection technique of Cai Yonging is reliable, but need special Grouting Pipe and complicated sealing device, " stop grouting plug " sealing device is all adopted in sealing between Grouting Pipe and the borehole wall at present, " stop grouting plug " adopts rubber, cork, plastic or other material, only seals no anchorage effect, when high-pressure slip-casting, sealing was easily lost efficacy, so grouting and reinforcing only is confined to use in the special engineerings such as urgency is repaiied, water blockoff up to now.
The purpose of this utility model be design a kind of novel with anchoring and sealing combine together, with anchoring and slip casting combine together, good sealing effect, practical anchor annotate integrated tubular type anchor cable.
The purpose of this utility model is achieved in that and adopts total length threaded steel pipe or seamless steel pipe to be made into anchor cable body (1), is divided into slip casting section (2), sealing anchoring section (3), free section (4) and tailing screw flight section (8) along length by its function.Because side slope, cutting and the general top layer of massif are weathered layer, loose, broken or be layer structure, large-scale underground engineering wall rock surfaces such as large cross-section tunnel, underground chamber, underground power house, intersection, tunnel are often own broken fully, formed the fragmentation circle of certain width, utilize the utility model, can realize the double Grouting Pipe of doing of anchor cable, slip casting is inner from geotechnical body, by lining and table, significantly improve the geotechnical body bulk strength, carry out anchoring by apply prestressing force to anchor cable again, prestress anchorage cable and grouting and reinforcing are organically combined, more effectively reinforce geotechnical body.At this key technical problem of the sealing between grouting cable anchor and the hole wall, the sealing cement anchor (5) that open circles ring body shape is hard, high-strength soon is placed in anchoring section (3) outside of anchor cable body (1), not only solved the sealing problem of anchor pouring reinforcement effectively, the leaking of slurries when having prevented high-pressure slip-casting, and played anchorage effect.
The utility model is owing to adopted fast hard, high-strength sealing cement anchor to seal and anchoring, solved the sealing problem of anchor pouring reinforcement effectively, improved the consolidation effect of prestress anchoraging, enlarge the scope of application of prestress anchorage cable in side slope, cutting, massif, large cross-section tunnel, underground chamber, underground power house isolith geotechnique journey, had characteristics such as cost is low, simple in structure, easy to operate, practical.
Fig. 1 is a structure chart of the present utility model.
Narrate embodiment of the present utility model according to Fig. 1 below: the utility model is made up of anchor cable body (1), slip casting section (2), sealing anchoring section (3), free section (4), supporting plate (6), nut (7) and tailing screw flight section (8) etc.Anchor cable body (1) adopts hollow total length threaded steel pipe or seamless steel pipe to make.The anchor cable body is divided into slip casting section (2), sealing anchoring section (3), free section (4) and tailing screw flight section (8).The length of anchor cable body (1) is 5～20 meters, and slip casting section (2) length is 1/2～2/3 of anchor cable body (1) total length, and sealing anchoring section (3) length is 2～4 meters, and tailing screw flight section (8) is about 100～200 millimeter.On slip casting section (2), be drilled with penetrating of cross-distribution and starch hole (9).The outside of sealing anchoring section (3) be the sealing cement anchor (5) of hard, high-strength soon torus shape, and the length of sealing cement anchor (5) and sealing anchoring section (3) are with length, and its front portion is welded with baffle ring (10).The material of sealing cement anchor (5) can be the rapid setting cement volume, and its internal diameter is more bigger than the external diameter of anchor cable body (1), and external diameter is then smaller than boring aperture.Can adjust the length of sealing anchoring section (3) according to the structural plane feature of geotechnical body, to seal cement anchor during use earlier and immerse 5～10 seconds in the water, and put into the boring tamping then and get final product, and can prevent effectively that like this high pressure slurries from leaking from hole, simultaneously play the anchoring effect again, improve consolidation effect.Then, carry out slip casting by anchor cable.At last, load onto supporting plate (6) at the afterbody of anchor cable body (1), tighten supporting plate nut (7) with fixing anchor cable.
Claims (3)
1. an anchor that is used for side slope, cutting, massif, tunnel, underground chamber isolith geotechnique Cheng Jiagu and supporting is annotated integrated tubular type anchor cable, it is characterized in that forming by the steel pipe type anchor cable body of making of total length threaded steel pipe or seamless steel pipe (1), slip casting section (2), sealing anchoring section (3), free section (4), supporting plate (6), nut (7), tailing screw flight section (8), the outside of sealing anchoring section (3) is the sealing cement anchor (5) of torus shape, and the front portion is welded with baffle ring (10).
2. a kind of anchor according to claim 1 is annotated integrated tubular type anchor cable, it is characterized in that: the length of sealing anchoring section (3) is 2～4m.
