Recyclable prefabricated composite soil nail wall support structure system based on anchor cables and soil nails

Abstract

The invention discloses a recoverable assembly type composite soil nailing wall supporting structure system based on anchor cables and soil nails. The recoverable assembly type composite soil nailing wall supporting structure system comprises a plurality of anchor cables arranged on a slope of a foundation pit in multiple rows and multiple columns, the recoverable soil nails are arranged between every two adjacent rows of anchor cables, each row of anchor cables are connected with the corresponding adjacent row of soil nails through panels, an anchorage section of each anchor cable is provided with a plurality of inner anchor heads with the width larger than that of the anchor cable so as to bear supporting force, and the anchor cables can be recovered. The recoverable assembly type composite soil nailing wall supporting structure system has the beneficial effects that all supporting structure components can be machined in a factorization manner, and assembling can be carried out for conducting construction; supporting materials are recoverable and can be recycled so that resources can be saved; and the construction cost is saved, the supporting materials cannot be left underground, and therefore construction of newly-built underground engineer on the periphery in the later period cannot be influenced.

Description

technical field [0001] The invention relates to foundation pit and side slope support, in particular to a recyclable assembled composite soil nail wall support structure system based on anchor cables and soil nails. Background technique [0002] Green building and building industrialization are the inevitable requirements of national ecological construction. At present, with the continuous advancement of urbanization in our country, there are more and more foundation pit projects. The composite soil nail wall support structure combined with prestressed anchor cable and soil nail wall has been widely used in foundation pit engineering, but only as a temporary support measure. After the construction of the main underground structure is completed, the composite soil nail wall is abandoned underground. Practice has proved that the prestressed anchor cables and soil nails left in the ground have become dangerous obstacles to the subsequent development of underground space, resu...
