Problems solved by technology

[0003] In the prior art, steel materials, such as steel bars, anchor rods and soil nails, are widely used in geotechnical engineering to reinforce foundation pits and slopes, and have achieved very good results, but the steel materials usually used are disposable , and the pole body remains in the soil layer after use, which not only wastes materials, but also forms obstacles to the construction of adjacent buildings, which increases the cost of dealing with underground obstacles during development

Embodiment Construction

[0017] The present invention is described below in conjunction with accompanying drawing.

[0018] Such as figure 1 Shown is a steel material with a fusible grip layer according to the present invention, which includes a steel body and a fusible grip layer 2; the fusible grip layer 2 is arranged outside the steel body to tightly wrap the steel material Body; in this embodiment, the steel body is a steel bar; of course, the steel bar body can also be steel pipe, steel strand, section steel; the fusible grip layer 2 is made of epoxy resin or plastic or wax or nylon become.

[0019] Such as figure 2 Shown is a schematic diagram of the application state of a steel material with a fusible grip coating according to the present invention. An anchor hole 4 is arranged in the rock and soil body 3, and the steel material with a fusible grip coating layer of this scheme is set in the anchor hole 4. , and then fill the concrete 5 to achieve the role of supporting the rock and soil mas...

Abstract

The invention relates to steel with a fusible wrapping layer. The steel comprises a steel body and a fusible wrapping layer. The fusible wrapping layer is arranged on the outside of the steel body to warp the steel body tightly. According to the steel with the fusible wrapping layer, when foundation pits or side slopes are supported, the supporting performance cannot be affected; and simultaneously, when the steel is needed to be recycled, the steel body can be electrified, so that the steel body emits heat, the fusible wrapping layer is softened or fused as the heat-conducting property of the steel is good, and frictional resistance between the steel body and the fusible wrapping layer is reduced, accordingly, recycling is facilitated; or the steel is heated through other modes, and the recycling can also be facilitated. The steel with the fusible wrapping layer is simple in structure, convenient to operate and practical.

Description

technical field [0001] The invention relates to a conveniently recyclable steel material with a fusible grip layer applied to foundation pits and side slope supports of geotechnical engineering. Background technique [0002] With the advancement of urbanization, the construction of underground facilities such as underground parking lots, underground pedestrian passages, underground commercial streets, and underground railways requires foundation pit and slope support. [0003] In the prior art, steel materials, such as steel bars, anchor rods and soil nails, are widely used in geotechnical engineering to reinforce foundation pits and slopes, and have achieved very good results, but the steel materials usually used are disposable , and the pole body remains in the soil layer after use, which not only wastes materials, but also forms obstacles to the construction of adjacent buildings, causing it to increase the cost of dealing with underground obstacles during development.
