Fill side slope gravity type retaining wall reinforcing structure and construction method thereof

Abstract

The invention provides a fill side slope gravity type retaining wall reinforcing structure and a construction method thereof. The reinforcing structure comprises an original gravity type retaining wall, a fill side slope above the retaining wall, a high-pressure rotary spraying reinforcement body constructed in the retaining wall foundation, a lattice anchor cable supporting structure constructedon the retaining wall and a slope reinforcing structure constructed on the soil filling side slope. According to the reinforcing structure, the original retaining wall foundation is subjected to high-pressure rotary jet reinforcement treatment, the bearing capacity of the retaining wall foundation is directly improved, the passive protection of the original retaining wall is changed into active protection of the lattice pressure type anchor cable, the anti-overturning, anti-slip and other stability of the original retaining wall is greatly improved, and the displacement of the retaining wall can be effectively controlled; and according to the upper fill side slope, a geogrid is laid in the filling soil, and the deformation condition of the soil body is improved and the engineering performance of the soil body is improved by utilizing the interaction between the geogrid and the filling soil of each layer, so that the stability of the upper fill side slope is guaranteed, and the adverseeffect of the upper filling soil on the original retaining wall can be effectively reduced.

Description

technical field [0001] The invention relates to the field of slope reinforcement, in particular to a filling slope gravity retaining wall reinforcement structure and a construction method thereof. [0002] technical background [0003] The gravity retaining wall uses the gravity of the retaining wall to maintain the stability of the retaining wall under the earth pressure behind the wall. Gravity retaining walls can be constructed of masonry or concrete and are generally made into a simple trapezoid. For natural slopes or building slopes of general height, gravity retaining walls are a widely used method of protection or governance. When the gravity retaining wall is used for building slope support in warehouses, industrial plants or other sites, the land utilization rate in the site is relatively high. Due to the change of the planned use of the site behind the wall, the situation of filling the site behind the wall to increase the height of the site Occurs from time to ti...

Problems solved by technology

Since the grouting body in the fixed section of the tensile anchor (cable) is in a tension state after the anchor is loaded in the working state, and the tensile strength of the grouting body is very small, the grout is prone to tension cracks in the working state, and groundwater It is very easy to penetrate into the inside of the bolt through cracks, resulting in poor long-term corrosion resistance of the tension anchor (cable) body and uneven stress
