Abstract

The invention discloses a composite steel capable of conveniently recovering a core material and a recovering method of a composite steel. The composite steel capable of conveniently recovering the core material comprises a steel body and a fusible gripping layer, wherein the fusible gripping layer is arranged at the outer part of the steel body and tightly wraps the steel body, and an electric heating device is arranged at the inner part or on the side wall of the fusible gripping layer. The recovering method of the composite steel capable of conveniently recovering the core material comprises the following steps of: 1, electrifying and heating the electric heating device until the fusible gripping layer is softened or melted; and 2, extracting the steel body. With the adoption of the composite steel capable of conveniently recovering the core material, in the foundation pit and slope supporting process, the supporting performance cannot be influenced; and meanwhile, when the composite steel needs to be recovered, the electric heating device can be electrified and heated to enable the fusible gripping layer to be softened or melted, thus weakening the frictional resistance between the steel body and the fusible gripping layer and reaching the purpose of conveniently recovering the composite steel. The recovering method of the composite steel capable of conveniently recovering the core material is simple and practical.

Description

A kind of bimetal and recovery method thereof that can conveniently reclaim core
Technical field
The present invention relates to a kind of bimetal and recovery method thereof that can conveniently reclaim core that is applied to geotechnical engineering foundation ditch and slope retaining.
Background technology
Along with the propelling of urbanization process, the construction of the underground installations such as underground parking, underground tunnel, subterranean commercial area, underground railway need to be carried out foundation ditch and slope retaining.
In the prior art, steel, be widely used in the geotechnical engineering such as reinforcing bar, anchor pole and soil nailing, be used for reinforcing foundation ditch and side slope, obtained extraordinary result of use, but the steel of usually using all are disposable uses, and using the rear body of rod is retained in the soil layer, not only waste material, also construction forms obstacle to adjacent structure, processes the expense of underground obstacle when causing it to increase exploitation.For this reason, reclaim in the urgent need to developing a kind of convenient steel that reclaim, not only making things convenient for, and in foundation ditch and slope retaining process, can not affect supporting performance.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of bimetal and recovery method thereof that can conveniently reclaim core that is applied to geotechnical engineering foundation ditch and slope retaining.
Technical solution of the present invention is achieved in that a kind of bimetal that can conveniently reclaim core, comprises steel body, the fusible layer that bonds; The described fusible outside that layer is arranged on the steel body that bonds tightly wraps the steel body; Described fusible bond the layer inside or sidewall on be provided with electric heater unit.
Preferably, the described fusible layer that bonds is made by epoxy resin.
Preferably, the described fusible layer that bonds is made of plastics.
Preferably, the described fusible layer that bonds is made by wax.
Preferably, the described fusible layer that bonds is made by nylon.
Preferably, the described recovery method that can conveniently reclaim the bimetal of core comprises following steps:
One, makes described electric heater unit heating power, until fusiblely bond the softening or fusing of layer;
Two, extract the steel body.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
The bimetal that can conveniently reclaim core of the present invention in foundation ditch and slope retaining process, can not affect supporting performance; Simultaneously, when needs reclaim, can switch on to electric heater unit, make to make fusible bond layer deliquescing or fusing, reduce steel body and the fusible frictional resistance that bonds between the layer, thereby reach the convenient purpose that reclaims; The recovery method of the described bimetal that can conveniently reclaim core is simple, practical.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the schematic diagram that can conveniently reclaim the bimetal of core of the present invention;
Accompanying drawing 2 is the application state schematic diagram that can conveniently reclaim the bimetal of core of the present invention;
Wherein: 1, reinforcing bar; 2, the fusible layer that bonds; 3, electric heater unit; 4, anchor hole; 5, concrete; 6, Rock And Soil; 7, electric wire.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Be illustrated in figure 1 as a kind of bimetal that can conveniently reclaim core of the present invention, comprise steel body, the fusible layer 2 that bonds; The described fusible outside that layer 2 is arranged on the steel body that bonds tightly wraps the steel body; Described fusible layer 2 inside that bond are provided with electric heater unit 3; In the present embodiment, described steel body is reinforcing bar 1; Certainly, described reinforcing bar body also can be steel pipe, steel strand, shaped steel; The described fusible layer 2 that bonds is made by epoxy resin or plastics or wax or nylon.Certain described electric heater unit 3 also can be arranged on fusible bonding on layer 2 the inside wall or lateral wall.
Be illustrated in figure 2 as a kind of application state schematic diagram that can conveniently reclaim the bimetal of core of the present invention, be provided with anchor hole 4 in the Rock And Soil 6, the bimetal that can conveniently reclaim core of this programme is set in the anchor hole 4, then fills up concrete 5, to reach the effect of supporting Rock And Soil 6.When the supporting purpose reaches, in the time of need to from anchor hole 4, taking out reinforcing bar 1, can switch on to electric heater unit 3, make electric heater unit 3 heatings, thereby make fusible bond layer 2 deliquescing or fusing, reduced steel body and the fusible frictional resistance that bonds between the layer 2, thereby reach the convenient purpose that reclaims; Can certainly heat to this programme by other means, also can realize same purpose.
The recovery method that can conveniently reclaim the bimetal of core of the present invention comprises following steps:
One, makes described electric heater unit 3 heating powers, until fusiblely bond the softening or fusing of layer; Two, extract the steel body.In the present embodiment, in the recovery method of the described bimetal that can conveniently reclaim core, connect electric wire 7 for first electric heater unit 3, then make electric wire 7 energisings, make electric heater unit 3 heatings, can make fusible bond layer 2 deliquescing or fusing, reduce reinforcing bar 1 and the fusible frictional resistance that bonds between the layer 2, thereby reach the convenient purpose that reclaims; Utilize at last professional tool, such as jack, extract reinforcing bar 1, can realize light recovery to reinforcing bar 1.
The bimetal that can conveniently reclaim core of the present invention in foundation ditch and slope retaining process, can not affect supporting performance; Simultaneously, when needs reclaim, can switch on to electric heater unit, make to make fusible bond layer deliquescing or fusing, reduce steel body and the fusible frictional resistance that bonds between the layer, thereby reach the convenient purpose that reclaims; The recovery method of the described bimetal that can conveniently reclaim core is simple, practical.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
