Abstract
The invention discloses a steel product with a fusible bounding layer and a recovery method thereof. T he steel product with the fusible bonding layer comprises a steel product body and the fusible bounding layer, wherein the fusible bounding layer is arranged on the outer part of the steel product body and tightly packages the steel product body. The recovery method of the steel product with the fusible bonding layer comprises the following steps of: I, heating the steel product until the fusible bonding layer is softened or melted; and II, pulling the steel product body out. According to the steel product with the fusible bonding layer, during a foundation ditch and slope supporting process, the support performance cannot be affected; simultaneously, when needing to be recovered, the steel product body is electrified so as to be heated, and the fusible bonding layer can be softened or melted due to favorable heat-conducting property of the steel product, so that frictional resistance between the steel product body and the fusible bonding layer is reduced, and the aim of convenience in recovery is achieved; and the recovery method of the steel product with the fusible bounding layer is simple and practical.
Description
Technical field
The present invention relates to a kind of be applied to geotechnical engineering foundation ditch and slope retaining can conveniently reclaim with the fusible steel that bond layer and described with the fusible recovery method of steel that bonds layer.
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 be applied to geotechnical engineering foundation ditch and slope retaining can conveniently reclaim with the fusible steel that bond layer and described with the fusible recovery method of steel that bonds layer.
Technical solution of the present invention is achieved in that a kind of with the fusible steel that bond layer, 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.
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, described with the fusible recovery method that bonds the steel of layer, comprise following steps:
One, makes described steel body self-heating cooking, 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:
Of the present invention with the fusible steel that bond layer, in foundation ditch and slope retaining process, can not affect supporting performance; Simultaneously, when needs reclaim, can give the energising of steel body, the good heat conductive performance of steel makes the steel body self-heating cooking, owing to can make fusible bond layer deliquescing or fusing, reduce steel body and the fusible frictional resistance that bonds between the layer, thereby reached the convenient purpose that reclaims; Perhaps heat to this programme by other means, also can realize same purpose; Described simple, practical with the fusible recovery method of steel that bonds layer.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is of the present invention with the fusible schematic diagram that bonds the steel of layer;
Accompanying drawing 2 is of the present invention with the fusible application state schematic diagram that bonds the steel of layer;
Accompanying drawing 3 is of the present invention with the fusible recovery view that bonds the steel of layer;
Wherein: 1, reinforcing bar; 2, the fusible layer that bonds; 3, Rock And Soil; 4, anchor hole; 5, concrete; 6, electric wire.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Be illustrated in figure 1 as of the present invention a kind of with fusible bond the layer steel, comprise the steel body, fusible bond the layer 2; The described fusible outside that layer 2 is arranged on the steel body that bonds tightly wraps the steel body; In the present embodiment, described steel body is reinforcing bar; 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.
Be illustrated in figure 2 as of the present invention a kind of with the fusible application state schematic diagram that bonds the steel of layer, be provided with anchor hole 4 in the Rock And Soil 3, arrange in the anchor hole 4 this programme with fusible bond the layer steel, then fill up concrete 5, to reach the effect of supporting Rock And Soil 3.When the supporting purpose reaches, in the time of need to from anchor hole 4, taking out reinforcing bar 1, can switch on to reinforcing bar, make reinforcing bar 1 heating, because the good heat conductive performance of reinforcing bar 1, can make fusible bond layer 2 deliquescing or fusing, reduce steel body and the fusible frictional resistance that bonds between the layer, thereby reach the convenient purpose that reclaims; Can certainly heat to this programme by other means, also can realize same purpose.
Be illustrated in figure 3 as of the present invention a kind ofly with the fusible recovery view of steel that bonds layer, described with the fusible recovery method that bonds the steel of layer, comprise following steps:
One, makes described steel body self-heating cooking, until fusiblely bond the softening or fusing of layer; Two, extract the steel body.In the present embodiment, described with in the fusible recovery method of steel that bonds layer, connect electric wire 6 for first reinforcing bar 1, then make electric wire 6 energisings, the good heat conductive performance of reinforcing bar 1 makes reinforcing bar 1 heating, owing to 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 reached 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.
Of the present invention with the fusible steel that bond layer, in foundation ditch and slope retaining process, can not affect supporting performance; Simultaneously, when needs reclaim, can give the energising of steel body, the good heat conductive performance of steel makes the steel body self-heating cooking, owing to can make fusible bond layer deliquescing or fusing, reduce steel body and the fusible frictional resistance that bonds between the layer, thereby reached the convenient purpose that reclaims; Perhaps heat to this programme by other means, also can realize same purpose; Described simple, practical with the fusible recovery method of steel that bonds layer.
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.
