Problems solved by technology

At this time, if the local geological conditions are soft soil layer, broken rock-soil layer or other complex geological conditions, coupled with the disturbance of the passing vehicles on the passing road to the vertical excavation slope, the vertical excavation slope will easily collapse. This is not only a serious safety hazard, but also brings difficulties to the construction

Embodiment Construction

[0031] This application is aimed at the construction scheme of the half width open to traffic and the half width implemented in the reconstruction and expansion project of the existing expressway, especially the stability reinforcement problem of the façade slope formed by the subgrade of the passing road section after the back of the half abutment abutment is excavated during the demolition of the old bridge. For example, see figure 1 , in the reconstruction project for road section A, it is assumed that the center line of the road surface is used as the boundary, and the north half (upper) is opened to traffic, and the south half (lower) is constructed to demolish the back of the old abutment.

[0032] refer to figure 2 , the embodiment of the present application provides a method for road reconstruction and establishment of excavated slope reinforcement, the method includes the following steps:

[0033] Step S110, according to the geotechnical physical and mechanical para...

Abstract

The invention discloses a highway reconstruction and expansion vertical slope strengthening method. A vertical slope is strengthened by arranging row protection piles and top beams, and the construction scheme of the row protection piles and top beams is obtained based on vertical slope rock-soil physical and mechanics parameters and vertical slope engineering size data. According to the method, digging and guniting construction is divided into three stages to be conducted, after digging in each stage is conducted, a spray protection steel wire mesh is installed and fixed immediately, gunitingstrengthening is conducted, and meanwhile, anchor cables are buried for further reinforcement; and by adopting the row protection piles, guniting rebar meshes and the anchor cables for protection, the structural stability of a roadbed vertical slope is effectively improved, and especially, under the vehicle passing condition, great safety guarantee is provided for platform back construction, platform base construction and platform body construction. Compared with steel plate pile protection piles, the bending strength is effectively improved.

Description

technical field [0001] The present application relates to the technical field of building structures, and in particular to a method for strengthening excavated side slopes in highway reconstruction. Background technique [0002] Usually, in expressway reconstruction and expansion projects, a half-width construction plan is implemented to reduce traffic inconvenience caused by construction and relieve urban traffic pressure under the condition of normal construction and reconstruction. [0003] When implementing the half-width half-width construction plan, especially after the half-width abutment back is excavated during the demolition of the old bridge, the subgrade of the traffic section forms a facade slope. At this time, if the local geological conditions are soft soil layer, broken rock-soil layer or other complex geological conditions, coupled with the disturbance of the passing vehicles on the passing road to the vertical excavation slope, the vertical excavation slope...
