Description

Novel reinforced retaining wall structure

Technical Field

The utility model belongs to building civil engineering field especially relates to a retaining wall for side slope protection.

Background

The retaining wall is a structure for supporting roadbed filling or hillside soil and preventing the filling or soil from deforming and destabilizing. The reinforced earth retaining wall is composed of three parts of filling, tie bars in the filling and wall panels, and the like, and the reinforced earth retaining wall cuts and reduces the lateral pressure of soil into the soil body through the friction action between the filling and the tie bars to play a role in stabilizing the soil body. The reinforced earth retaining wall belongs to a flexible structure and has strong adaptability to foundation deformation.

However, the structure of the conventional retaining wall is calculated according to the conventional retaining wall principle and the loose soil structure, so that the general excavated surface of the bottom is large. In the slope protection engineering of some buildings, the site is not suitable for large-area excavation, and certain difficulty is brought to engineering construction. In addition, the overlarge structure of the retaining wall also increases the construction cost, and restricts the application range of the retaining wall.

Disclosure of Invention

In order to solve the technical problem, the utility model provides a novel muscle retaining wall structure adds.

In order to achieve the above purpose, the utility model adopts the technical scheme that:

a novel reinforced retaining wall structure is characterized by comprising an inner wall body and an outer wall body; the outer wall body is a poured reinforced concrete wall body, the section of the outer wall body is in a right trapezoid shape, the thickness of the bottom of the outer wall body is calculated according to 12% of the height of the wall body and is not less than 0.5 m, and the thickness of the top of the outer wall body is designed to be 0.2-0.3 m; the inner wall body is a three-dimensional square lattice body formed by building, and dry clay is backfilled and tamped in the lattice space at each building layer, wherein the vertical face of the innermost lattice space, which is in contact with the original soil body, is the original soil body serving as the lattice wall, so that the dry clay and the original soil body are tamped together, and the vertical face of the outermost lattice space, which is in contact with the outer wall body, is the outer wall body serving as the lattice wall, so that the dry clay and the outer wall body are tamped together.

Because the inner wall body is a three-dimensional square body built by building bricks and is backfilled with the dry vegetarian clay, when the three-dimensional square body is built by the building bricks, one layer of the dry vegetarian clay is backfilled every building layer, and the process is finished layer by layer from the bottom layer to the top layer.

Explanation: the bottom thickness refers to the length of the lower base of the right trapezoid, and the top thickness refers to the length of the upper base of the right trapezoid.

The building block brick can also be one of clay brick, gangue brick, fly ash brick, in-situ stone block and the like. Or more than two of building block bricks, clay bricks, gangue bricks, fly ash bricks, in-situ stone blocks and the like are mixed for use.

The length and the height of each lattice of the three-dimensional square lattice body are designed to be 0.7-1.0 meter, the width of each lattice is in accordance with the following principle, the inner wall body is not divided into two lattices when the width is less than 1.0 meter, is divided into two lattices when the width is more than or equal to 1.0 meter and less than 2.0 meters, is divided into three lattices when the width is more than or equal to 2.0 meters and less than 3.0 meters, and the like.

The utility model discloses a theory of operation and positive effect: the block brick three-dimensional grid structure plays a role in reinforcing, the lateral pressure of soil is cut and reduced into the soil body through the friction effect of filling and the block brick structure, the effect of stabilizing the soil body is achieved, the problem that the section of the traditional retaining wall structure is too large is solved, the construction difficulty and the engineering cost are reduced, the retaining wall has stronger applicability, and the market competitiveness is improved; the utility model discloses it is big to ground deformation adaptability, can be used in the high very high occasion of bank protection height needs.
