Construction method of composite barricade with massif sloping field based on gravity and geogrid reinforcement

Abstract

The invention relates to a construction method of a composite barricade with a massif sloping field based on gravity and geogrid reinforcement. The construction method includes the following steps that A, a slide-resistant pile construction is carried out, wherein slide-resistant piles are evenly arranged along a wall foot positioning line positioned in advance; B, breast boards are installed, wherein the breast boards are installed on the inner sides of the slide-resistant piles, and gaps between adjacent slide-resistant piles are stopped; C, flat filling of a foundation is carried out, wherein the combining part of the foundation and an original slope is dug to be in a step shape, foundation soil with the geogrid paving scope is removed, and the foundation is subject to replacement treatment through reinforced soil; D, geogrid paving is carried out; and E, the step D is repeated until the barricade structure design elevation is obtained. According to the construction method, throughthe slide-resistant piles and the breast boards, the barricade bearing force is improved, the barricade horizontal displacement is prevented, the requirement for the barricade bearing force is met, the construction cost of projects is saved, and the green and eco-environment protection requirement is met.

Description

technical field [0001] The invention belongs to the field of construction of retaining walls on mountain slopes, in particular to a construction method of a gravity-based and geogrid-reinforced composite retaining wall on mountain slopes. Background technique [0002] Retaining wall, referred to as retaining wall, refers to a structure that supports roadbed fill or hillside soil and prevents the deformation and instability of fill or soil. A building that can resist lateral earth pressure and is used to support natural or artificial slopes and keep the soil stable. There are currently two common forms of retaining walls: gravity retaining walls and geogrid-reinforced retaining walls. [0003] Gravity retaining wall maintains the stability of the retaining wall under the action of earth pressure by the weight of the retaining wall itself. It is a kind of retaining wall commonly used in our country. Gravity retaining walls can be used as masonry blocks, flakes, and prefabri...

AI Technical Summary

Problems solved by technology

However, the geogrid reinforced retaining wall has low bearing capacity and is easy to deform. The slope is washed by rain for a long time, and it is easy to produce horizontal displacement.
