Retaining wall structure with composite foundation and reinforced gabions and construction method

Abstract

The invention discloses a retaining wall structure with a composite foundation and reinforced gabions and a construction method. The retaining wall structure is composed of the composite foundation (1), the multiple reinforced gabions (2), a geogrid (3), inverted filter layers (4) and filling bodies (5). The composite foundation (1) is located underground and composed of a plurality of vibration blunt gravel piles (1.1), the multiple reinforced gabions (2) are stacked on the upper portion of the composite foundation (1), the filling bodies (5) are arranged on the inner sides of the reinforcedgabions (2), and the geogrid (3) is arranged on the lower portions of the filling bodies (5). The inverted filter layers (4) are arranged between the reinforced gabions (2) and the filling bodies (5).According to the retaining wall structure and the construction method, the defects that in the prior art, the bearing capacity of a foundation is low, and a retaining wall and filling bodies behind the wall greatly deform accordingly and are even instable to be damaged are overcome, and the retaining wall structure and the construction method have the advantages that construction is easy and convenient, the construction speed is high, and the wall body manufacturing cost is low.

Description

technical field [0001] The invention relates to the technical fields of water conservancy, highway, water and soil conservation, etc., and more specifically relates to a composite foundation reinforced gabion retaining wall structure and a construction method. Background technique [0002] During the filling process of revetment embankment, highway embankment, spoil yard and other projects, retaining walls are usually used to resist the filling pressure. When the above-mentioned engineering construction is located in coastal areas, river and lake banks, soft soil areas, and deep overburden areas, the stratum structure is mostly composed of silty sand, silt, silty clay, and silty soil. The traditional retaining wall structure cannot meet its own requirements. In order to meet the stability requirements of the filling body behind the wall, other methods must be combined with the retaining wall to jointly bear the filling pressure behind the wall.

Problems solved by technology

When the above-mentioned engineering construction is located in coastal areas, river and lake banks, soft soil areas, and deep overburden areas, the stratum structure is mostly composed of silty sand, silt, silty clay, and silty soil. The traditional retaining wall structure cannot meet its own requirements. In order to meet the stability requirements of the filling body behind the wall, other methods must be combined with the retaining wall to jointly bear the filling pressure behind the wall.

[0003] Traditional retaining wall materials are concrete or masonry masonry. Concrete retaining walls involve concrete production, transportation, and pouring, with many construction equipment and complicated procedures; masonry masonry walls require manual masonry, which consumes a lot of manpower and slow construction speed

Chinese patent CN104674841B uses machinery to place block stones to quickly form a retaining wall. Although the degree of mechanized construction of the retaining wall has been improved and the construction speed of the retaining wall has been accelerated, it faces the same problem as the concrete retaining wall and the masonry masonry retaining wall: When encountering the above-mentioned poor geological conditions, due to the low bearing capacity of the foundation, the retaining wall and the filling body behind the wall will experience large deformation and even failure. layer foundation use

Although the Chinese patents CN205116214U, CN104389320B, and CN103321243B use cast-in-situ piles, steel pipe micro-piles, screw piles, rotary spray piles, and mixing piles to reinforce the foundation of the retaining wall, the above-mentioned piles are all plain concrete or reinforced concrete structures, and the construction process is complicated. , long construction period and high project cost

[0004] When the height of the filling body behind the retaining wall is high, only relying on the retaining wall itself to resist the filling pressure will make the masonry structure bulky. At the same time, the requirements for the bearing capacity of the foundation are high, and the construction cost is also high
