Abstract

The invention provides an old retaining wall provided with a stretching buffer layer for treatment, and belongs to the technical field of pavement infrastructure engineering. The old retaining wall provided with the stretching buffer layer for treatment comprises a left underground layer, a right underground layer is fixedly connected to one side face of the left underground layer, and an existing retaining wall is fixedly connected to the inner wall of the left underground layer. The tensile buffer layer is arranged, the elasticity and the bearing capacity of a soil body are utilized, the pavement load is released, the situation that a newly-built road is damaged by the counter-acting force of an old retaining wall on the lower layer is avoided, meanwhile, the two-way double-layer reinforcing band is arranged, and the integrity and the adaptability of the tensile buffer layer can be improved. Internal stress and differential settlement caused by non-uniform materials of an old retaining wall on the lower layer, an original road bed and a surrounding backfill soil layer are effectively reduced, so that the strength of a newly-built pavement is better enhanced, and long-term use is facilitated.

Description

technical field [0001] The invention belongs to the technical field of pavement infrastructure engineering, and in particular relates to a method for treating old retaining walls with stretch buffer layers. Background technique [0002] In the design and construction of road expansion and widening projects, old retaining walls matching the original roads are often encountered. The old retaining wall plays the role of supporting the original road structure system and maintaining the stability of the slope where the original road and the surrounding natural ground are at a height difference. The existing construction technology for dealing with the old retaining wall is: large excavation Completely abolished construction method, in which all retaining walls are excavated and smashed, and earthwork is backfilled on the original site to build the subgrade of the new road. The rate method grading and large excavation of the surrounding earthwork is to maintain the stability of t...
