Abstract
The invention discloses combined steel with core materials convenient to recover and a recovery method of the combined steel with the core materials convenient to recover. The combined steel with the core materials convenient to recover comprises a steel body and a fusible holding wrapping layer, wherein the fusible holding wrapping layer is provided with a plurality of sections which are arranged on the outer portion of the steel body at intervals and tightly wraps the steel body, a sleeve is arranged between adjacent sections of the fusible holding wrapping layer, each sleeve wraps the steel body, and an electric heating device is arranged at the inner portion or on the side wall of each section of the fusible holding wrapping layer. The recover method of the combined steel with the core materials convenient to recover includes a first step of enabling each electric heating device to be turned on to heat until the fusible holding wrapping layer softens or fuses and a second step of extracting the steel body. The combined steel with the core materials convenient to recover cannot influence support performance in the process foundation ditch support and slope support. Meanwhile, when the combined steel with the core materials convenient to recover is needed recovering, each electric heating device is turned on and heat to enable the fusible holding wrapping layer to soften or fuse, friction resistance between the steel body and the fusible holding wrapping layer is reduced, and therefore a purpose of convenient recovery is achieved. The recovery method of the combined steel with the core materials convenient to recover is simple and practical.
