Combined earth retaining wall structure and construction method thereof

Abstract

The invention discloses a combined earth retaining wall structure and a construction method thereof. A platform is arranged under a common concrete wall body; the lower part of the platform is provided with a straight steel tube concrete anchor pile, an oblique steel tube concrete anchor pile and a wall bottom reinforcing region; and anti-slide steel piles are arranged at the outer side of the wall surface of the common concrete wall body. The construction method comprises the following steps of: stirring and reinforcing a soft soil region at the lower part of a soil blocking wall in construction; installing the straight steel tube concrete anchor pile, the oblique steel tube concrete anchor pile and the anti-slide steel piles; placing a platform reinforcing mesh, and welding the platform reinforcing mesh with the top parts of the straight steel tube concrete anchor pile and the oblique steel tube concrete anchor pile, and pouring platform concrete; and placing a bottom reinforcing mesh and a lateral reinforcing mesh, welding the top parts of the anti-slide steel piles and the lateral reinforcing mesh, and pouring common concrete. According to the combined earth retaining wall structure and the construction method, the safety and the reliability of the soil blocking wall at the soft soil region can be ensured; the integral stability of the soil blocking wall can be enhanced; the deformation settlement of the soil blocking wall can be reduced; and the integral slippage and overturn damage on the soil blocking wall can be prevented.

Description

technical field [0001] The invention relates to a foundation structure in the construction field and a construction method thereof, in particular to a retaining wall suitable for building slopes and road slopes in various soft soil areas and a construction method thereof. Background technique [0002] At present, retaining walls are mainly used to maintain the stability of slopes in soft soil areas and prevent landslides in soft soil areas. A retaining wall refers to a structure that supports roadbed fill or hillside soil and prevents the deformation and instability of fill or soil. Due to the low strength of the soft soil and the high compressibility of the soil at the lower part of the retaining wall, the upper retaining wall is very prone to overall sliding damage and overturning damage, leaving a safety hazard for the project and causing huge economic losses. loss. [0003] At present, the design and construction methods of retaining walls in soft soil areas and non-so...
