Abstract

The invention provides a recoverable soil nail and a method for construction with the recoverable soil nail. The recoverable soil nail comprises a soil nail end, a tubular soil nail body, a grouting pipe and an outer sleeve. The soil nail end comprises a nail point, an end plate and a connection pipe, the nail point, the end plate and the connection pipe are welded sequentially, a sealing partition provided with a via hole is arranged in the connection pipe, and the outer wall of the connection pipe is provided with an external thread. The soil nail body is formed by sequential threaded connection of at least two soil nail sections, adjacent soil nail sections are positioned through anti-rotating pins, the soil nail section at one end is in threaded connection with the connection pipe, and the outer wall of each soil nail section is provided with an external thread. One end of the grouting pipe is penetratingly arranged in the via hole of the sealing partition, and the other end of the grouting pipe penetrates out of the whole soil nail body. The inner wall of the outer sleeve is provided with an internal thread, and the outer sleeve sleeves the connection pipe and the soil nail body through the thread. By the sectional structure, soil nail recovery in a narrow space is realized.

Description

technical field [0001] The invention relates to the field of soil nail support structures, in particular to a recyclable soil nail and a construction method using the recyclable soil nail. Background technique [0002] Soil nailing is a new soil retaining technology for building foundation pits and slope stability. It has been widely used because of its economy, reliability, quick and easy construction. Soil nailing makes full use of the strength of the foundation soil itself, and the purpose of support is achieved by setting soil nails while excavating the soil. The stress behavior of soil nails is different from that of bolts. Bolts are generally provided with a free section and an anchor section, and provide greater pull-out resistance by stabilizing the anchor section in the soil at the far end. Compared with the anchor rod, the soil nail is usually not long and the tensile force it receives is generally small. The conventional method is to use the full-length grouting ...
