Problems solved by technology
[0002] At present, with the rapid development of my country's economic construction, more and more engineering projects need slope treatment during construction. Gravity retaining walls are widely used in my country's railways, highways, water conservancy, harbors, mines and other projects. However, due to Its volume and weight are large, and its construction on weak foundations is often limited by its bearing capacity.
If the wall is too high, it consumes a lot of materials and is not economical

Embodiment Construction
[0023] The present invention will be further described below in conjunction with specific embodiments. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0024] Below in conjunction with accompanying drawing and embodiment the patent of the present invention is further described.
[0025] like Figure 1-3 As shown, the present invention provides a manhole composite reinforced soil high retaining wall, including an inner retaining wall near the slope side and an outer retaining wall on the far side of the slope, and the inner retaining wall and the outer retaining wall pass through several geogrids One end of the geogrid is fixed on the steel wire mesh reserved for the outer retaining wall through a low-carbon steel wire, and the other end is wound on the inner retaining wall; a geotechnical grid composed of medium or coarse sand materials is arranged...

The invention provides a manhole compound type high reinforced-soil retaining wall. The manhole compound type high reinforced-soil retaining wall comprises an internal retaining wall close to a side slope side and an external retaining wall far away from the side slope side, the internal retaining wall and the external retaining wall are connected through a plurality of geogrid, and one end of each geogrid is fixed on a steel wire mesh reserved on the external retaining wall through a low carbon steel wire, and the other end of each geogrid is wound on the internal retaining wall; and geotechnical fillers are arranged between the geogrid. In addition, the invention further provides a manufacturing method for the manhole compound type high reinforced-soil retaining wall.
Description
technical field [0001] The invention relates to a manhole composite reinforced soil high retaining wall and a manufacturing method thereof, belonging to the field of civil engineering. Background technique [0002] At present, with the rapid development of my country's economic construction, more and more engineering projects need slope treatment during construction. Gravity retaining walls are widely used in my country's railways, highways, water conservancy, harbors, mines and other projects. However, due to Its volume and weight are large, and its construction on weak foundations is often limited by its bearing capacity. If the wall is too high, it consumes a lot of materials and is not economical. Reinforced earth retaining walls are being used more and more, and reinforced retaining fill plays an important role in high fill projects. The water permeability of the retaining wall has a great influence on the performance of the retaining wall. The pullout resistance provi...
