Abstract
The utility model relates to an improved clamping sheet type anchorage device which comprises an anchoring ring assembly, a clamping sheet assembly, a protective sleeve, and an insulation sleeve. The anchoring ring assembly is provided with an anchoring hole. An expanding part is arranged in the anchoring hole. The protective sleeve is arranged in the anchoring hole. When the clamping sheet assembly is inserted into the anchoring hole, the protective sleeve is clamped in the anchoring hole through the anchoring ring assembly and the clamping sheet assembly. The insulation sleeve is arranged on the end portion of the anchoring ring assembly. The protective sleeve is provided with an electric heating device and is made of fusible materials. The improved clamping sheet type anchorage device can bear 28-ton drawing force in the foundation ditch and slope supporting process and fully meets requirements of current supporting. Meanwhile, when recovering is needed, a guide line can be used for heating an electric heating device so as to enable the protective sleeve to be softened or fused, and friction resistance between core materials and the clamping sheet assembly is reduced or removed, and therefore the purpose of recovering the core materials conveniently is achieved. The improved clamping sheet type anchorage device is simple in scheme and practical. Moreover, the core material recovering method is simple and convenient to implement.

Technical field
The utility model relates to a kind of being applied to can realize the large-tonnage drawing in geotechnical engineering foundation ditch and the slope retaining, and the convenient improved strand tapered anchorage of realizing that core reclaims.
Background technology
Along with the propelling of urbanization process, the construction of underground installations such as underground parking, underground walkway, subterranean commercial area, underground railway need be carried out foundation ditch and slope retaining.
In the prior art, be widely used in the geotechnical engineering as castinplace pile, anchor pole and soil nailing, core raw material as main bearing member is steel, as reinforcing bar, steel pipe, steel strand, wire rope, be used for reinforcing foundation ditch and side slope, obtained extraordinary result of use, but the steel of using all are disposable uses usually, and use the back core and all be retained in the soil layer, not only waste material is also constructed to adjacent structure and is formed obstacle.Rock-bolt length as common employing substantially all reaches 20-30 rice, and soil nailing reaches 8-15 rice, is difficult to it is reclaimed according to prior art.In considerable case history, adjacent structure because the influence of anchor pole, soil nailing has to take special working measure, is handled difficulty and the expense of underground obstacle when having increased exploitation greatly in follow-up construction.For this reason, press for a kind of strand tapered anchorage and the core recovery method thereof that can conveniently tear core open of exploitation, not only convenient recovery, and in foundation ditch and slope retaining process, can not influence supporting performance.
The utility model content
At the technical problem of above-mentioned existence, the purpose of this utility model is: propose a kind of being applied to and can realize the large-tonnage drawing in geotechnical engineering foundation ditch and the slope retaining, and the convenient improved strand tapered anchorage of realizing that core reclaims.
For achieving the above object, the technical solution adopted in the utility model is: a kind of improved strand tapered anchorage comprises anchor ring assembly, intermediate plate assembly, sheath, disrance sleeve; Described anchor ring assembly is provided with anchor hole; Be provided with the expansion section in the described anchor hole; Described sheath is arranged in the anchor hole; When the intermediate plate assembly inserted anchor hole, described sheath was clamped in sheath in the anchor hole by ground tackle assembly, intermediate plate assembly; Described disrance sleeve is arranged on the end of anchor ring assembly; Described sheath is provided with electric heater unit.
Preferably, described improved strand tapered anchorage also comprises lead, and described lead is electrically connected with electric heater unit.
Preferably, described sheath is made by epoxy resin or plastics or wax or nylon.
Preferably, the outer setting of described anchor ring assembly has reinforcing portion.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
Improved strand tapered anchorage of the present utility model in foundation ditch and slope retaining process, can bear 28 tons pulling capacity, can be fit to the structural strength of 26 tons of φ 15.2 steel strand, thereby satisfies existing supporting needs fully; Simultaneously, when needs reclaim, can utilize lead energising to make the electric heater unit heating, can make the softening or fusing of sheath, reduce or removed frictional resistance between core and the intermediate plate assembly, thereby reach the purpose of convenient recovery core; Improved strand tapered anchorage described in the utility model is simple in structure, practical, and its core recovery method is simple, and it is convenient to implement.
