It includes: a cantilever retaining wall (1), which is arranged on the outside of the embankment slope; reinforcement piles (2), which are arranged at intervals longitudinally along the line; a buttress connecting wall (3), which is arranged on the cantilever retaining wall (1) and the reinforcement piles (2) ) between and consolidated with it; the reverse filter layer (4) is fixedly arranged on the inner side of the cantilever retaining wall (1).

Description

High cantilever combined retaining wall structure

technical field

The invention relates to high-fill embankment slope closure structures for railways, highways, municipal engineering, etc., and in particular to a high-cantilever combined retaining wall structure.

Background technique

In the construction of roads and municipal projects in our country, there are usually requirements for slope closure of embankments in special sections, especially for railway stations, which require slope closure of high-fill embankments due to the needs of site, landscape and special projects. Traditional shoulder walls, embankment pile-slab walls, and pile foundation joists have problems such as limited appearance requirements, limited slope height, large cantilever height deformation, and special engineering structure forces that cannot meet the requirements. The new cantilever retaining wall and buttress The appearance of the cantilever retaining wall is good, but the same as the traditional slope closing structure, its slope closing height and service conditions are limited. Use is restricted in areas with bad geology and high-intensity earthquakes. Therefore, there is an urgent need for a new structure with good structural integrity, high strength, good slope closing effect, wide application range, simple construction technology, effective reduction of construction costs, and compliance with environmental protection requirements.

Contents of the invention

The technical problem to be solved by the present invention is to provide a high cantilever combined retaining wall structure with good integrity, high structural strength and good slope closing effect, so as to effectively solve the problem of high embankment slope closing.

The technical solution adopted by the present invention to solve its technical problems is as follows:

The high cantilever combined retaining wall structure of the present invention is characterized in that it comprises: a cantilever retaining wall arranged outside the side slope of the embankment; reinforcing piles arranged longitudinally along the line at intervals; a buttress connecting wall arranged between the cantilever retaining wall and the reinforcing piles And consolidated with it; the anti-filter layer is fixedly arranged on the inner side of the cantilever retaining wall.

The beneficial effect of the present invention is that it effectively solves the problem of slope closure of high embankments, and overcomes the limitation of the slope closure height of the traditional retaining wall structure and the new cantilever type retaining wall and buttress type retaining wall, the limited use conditions, the anti-sliding of the retaining wall structure and the Overturning and other problems, the structure has good integrity, high structural strength, good slope closing effect, wide application range, simple construction process, and can reduce the project cost by more than 10%, and meets environmental protection requirements, and has broad application prospects.

Description of drawings

This manual includes the following drawing:

Fig. 1 is a three-dimensional schematic diagram of a high cantilever combined retaining wall structure of the present invention.

The figure shows component names and corresponding marks: cantilever retaining wall 1, reinforcement pile 2, buttress connecting wall 3, and filter layer 4.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Referring to Fig. 1, the high cantilever combined retaining wall structure of the present invention includes: a cantilever retaining wall 1, which is arranged on the outside of the embankment slope; reinforcement piles 2, which are arranged at intervals along the longitudinal direction of the line; buttress connecting walls 3, which are arranged on the cantilever retaining wall 1 Between and consolidated with the reinforcement pile 2; the reverse filter layer 4 is fixedly arranged on the inner side of the cantilever retaining wall 1. The present invention uses the cantilever retaining wall 1 to close the slope of the embankment, and the reinforcement pile 2 provides the anti-sliding force and anti-overturning force to the cantilever retaining wall, effectively solving the main problems of anti-sliding and anti-overturning in the retaining wall structure; Provide the resistance of the reinforcement pile 2 to the cantilever retaining wall 1, and greatly improve the structural force of the cantilever retaining wall 1, and set the anti-filter layer 4 to discharge the cantilever retaining wall 1 and fill the soil for water seepage. The combined retaining wall structure effectively solves the problem of high embankment slope closure, and overcomes the limitation of the traditional retaining wall structure and the new cantilever retaining wall and buttress retaining wall. The structure has good integrity, high structural strength, good slope closing effect, wide application range, simple construction technology, and can reduce the project cost by more than 10%, and meets environmental protection requirements, and has broad application prospects.

The buttress connection wall 3, the cantilever retaining wall 1, and the reinforcement pile 2 are casted simultaneously with reinforced concrete to form a whole, and the main reinforcements thereof overlap each other. The structural size and reinforcement of the cantilever retaining wall 1 shall meet the requirements of the earth pressure behind the retaining wall. At the bottom of the cantilever retaining wall 1, drainage holes are arranged at intervals, the spacing is generally 1-2m, and the hole diameter is generally Φ80mm. The thickness of the reverse filter layer 4 is 0.3-0.5m. The thickness of the arm connecting wall 3 is not less than 0.6m, and not greater than the width of the reinforcement pile 2 .

The above description is only to illustrate some principles of the present invention, not to limit the present invention to the specific structure and scope of application shown and described, so all corresponding modifications and equivalents that may be used belong to this invention. The scope of the patent application for the invention.
