Abstract
The utility model relates to a local explosion hole reaming anchoring device, comprising a high-strength rod member, several explosion force sealing plates are disposed on the high-strength rod member at intervals, explosive packages are disposed at the end of the lower part of the high-strength rod member and between two explosion force sealing plates, and fuses of the explosive packages are arranged along the high-strength rod member. The local explosion hole reaming anchoring device, via placement of the explosive packages on the high-strength rod member at intervals, uses explosion force generated during explosion of the explosive packages to realize local hole reaming to enlarge the slurry cross section of a hole reaming part after grouting. Then an explosion hole reaming device is taken out, the hole is cleaned, an anchor rod is placed in the hole, and grouting injection and anchoring are performed. The anchoring technology effectively improves effect of reinforcing a slope, strengthens slope safety, effectively shortens anchoring depth, saves length of a drill hole, an anchor rod, and grouting (or an anchor rod diameter), reduces construction cost, and is provided with important social and economic meanings.
Description
Technical field
The utility model relates to a kind of a kind of local explosion reaming anchor device that can be widely used in the reinforcing of soil-slope, broken rock side slope.
Background technology
Along with the develop rapidly of geotechnical engineering, anchoring has become important branch wherein.In geotechnical engineering, adopt anchoring, can fully excavate the ground energy, call self intensity and self-bearing capacity of ground, alleviate dead load greatly, practice thrift engineering material, obtain the remarkable economical effect, and guarantee construction safety and engineering stability.At present; China mainly adopts cylindrical anchoring body anchor pole, and such anchor pole supporting capacity in some stratum is difficult to reach designing requirement, and the anchor pole reliability is poor; Often cause duration delay or engineering accident etc., cause great harm and loss for the country and people's lives and properties.Usually when prestressed anchor designs,, just take to increase the method for anchorage length, in the hope of reaching the purpose that enough anchored force are provided if the pore-creating of major diameter anchor hole at need.Practical experience for many years shows that in interior anchoring section, shear stress is not again that total length is all stressed neither evenly distribute, but near interior anchoring section oral area, has the stress of height to concentrate, and the phenomenon of plastic failure appears in the part rock mass that exists port.Obviously, increase anchorage length merely and can not effectively increase anchored force, increase anchoring section length lack of science simply.
Summary of the invention
The purpose of the utility model is for overcoming the deficiency of above-mentioned prior art; A kind of local explosion reaming anchor device is provided; This device can effectively improve the slope reinforcement effect, when strengthening side slope safety, effectively shortens anchorage depth; Save boring, anchor pole and grouting length (or bolt diameter), reduce construction costs.
For realizing above-mentioned purpose, the utility model adopts following technical proposals:
A kind of local explosion reaming anchor device; Comprise a high-strength rod member; Be interval with some force of explosion closure plate on the said high-strength rod member, install the blasting charge in the middle of the lower end of said high-strength rod member and the two force of explosion closure plate, the fuse of the blasting charge is arranged along high-strength rod member.
The utility model is through lay cartridge bag at interval on high-strength rod member, the force of explosion that produces when utilizing blasting charge explosion is realized local reaming, to strengthen the slurry cross section at reaming position, grouting back.Then the explosion Counterboring apparatus is taken out, anchor pole is inserted, the slip casting anchoring in clear hole in the hole.This anchoring is effectively improving the slope reinforcement effect, when strengthening side slope safety, effectively shortens anchorage depth, saves boring, anchor pole and grouting length (or bolt diameter), reduces construction costs, has important society and economic implications.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 2, a kind of local explosion reaming anchor device comprises a high-strength rod member 2, is interval with the vertical force of explosion closure plate 3 of some and said high-strength rod member 2 on the said high-strength rod member 2, and force of explosion is concentrated in the time of guaranteeing the cartridge bag explosion.Install the blasting charge 4 on the high-strength rod member 2 in the middle of the lower end of said high-strength rod member 2 and the two force of explosion closure plate 3, the fuse of the blasting charge 4 is arranged along high-strength rod member 2.
The concrete method for using of the utility model is following:
1, makes novel explosion Counterboring apparatus (Fig. 2) in advance; Different parts at high-strength rod member 2; Weld force of explosion closure plate 3 at interval, and install the blasting charge 4, lay the explosive of some in the blasting charge 4 in advance in the lower end and two force of explosion closure plate, 3 centres of high-strength rod member.
2, in the soil body that needs reinforcement or the boring of rock mass 5 side slope places, aperture and boring length should guarantee to insert smoothly explosion Counterboring apparatus shown in Figure 2.When being bored into projected depth, stop boring.
3, the explosion Counterboring apparatus that will make in advance inserts boring, and is as shown in Figure 3, guarantees that the fuse of the blasting charge 4 stretches out outside the hole.
4, the fuse of explosive blasting bag, the ignition charge bag.
5, wait to ignite finish after, take out the explosion Counterboring apparatus, clean the dirt above it use so that continue next time.
6, the boring that will pass through after the explosion is cleaned out, and inserts common bolt 1 then, injects cement mortar and forms injecting cement paste 6, accomplishes anchoring.
Claims (2)
1. a local explosion reaming anchor device is characterized in that: comprise a high-strength rod member, be interval with some force of explosion closure plate on the said high-strength rod member, install the blasting charge in the middle of the lower end of said high-strength rod member and the two force of explosion closure plate.
2. local explosion reaming anchor device according to claim 1 is characterized in that: the fuse on the said blasting charge is arranged along high-strength rod member.
