Description

A High and Steep Reinforced Slope Structure

technical field

The utility model relates to a high and steep reinforced slope structure. the

Background technique

At present, with the rapid development of my country's economic construction, a large number of ports, wharfs, roads, railways and other projects have been built in areas with poor terrain conditions such as the middle and upper reaches of the Yangtze River. Due to the complex terrain, high filling is required when land areas or roads are formed. Generally, two methods are adopted for high fill slopes: 1. Grading according to the natural slope; 2. Setting masonry retaining walls. Slope grading for high-fill slopes will occupy a large area; setting masonry retaining walls for high-fill slopes can overcome the problem of large land occupation, but if the masonry structure is too high, not only the project investment is high, the landscape effect is poor, and The structure itself has many potential safety hazards. the

Detailed ways

Further illustrate the embodiment of the present utility model below in conjunction with accompanying drawing. the

Referring to Figures 1 and 2, a high and steep reinforced slope structure, after back excavating steps 1008 for the filling base, cast-in-place concrete foundation 1005, and then layered tamping and filling of sandstone filler 1007, layered stacking and paving grid The gabion 1002 and the gabion cage 2001 are filled with filler stones 2002 to form the gabion 1002; the mesh structure of the gabion cage 2001 is hexagonal, and the tail of the gabion 1002 is provided with a lacing net 2003 and a lacing net 2003 The network structure is hexagonal; the grid 1004 is a uniaxially stretched polyethylene soil grid, and the gaps between the grids 1004 of each layer are filled with fillers 1007, and the fillers 1007 are extremely sandstone fillers. Layered tamping, filler 1007 has gradation requirements, and the gradation requirements are unevenness coefficient Cu≥5, curvature coefficient Cc=1~3; gabion cage 2001 and lacing mesh 2003 are both galvanized and plastic-coated low-carbon steel wire materials It is formed by mechanical double-twisting, the grid 1004 and the lacing net 2003 are bound and connected with galvanized plastic-coated low-carbon steel wires, and the back of the gabion 1002 is laid with a non-woven geotextile 2007. A concrete platform 1003 is arranged between two adjacent high and steep reinforced slope bodies, and the concrete platform 1003 is closed with cast-in-place concrete. the

In order to form a reinforced slope structure during the filling process, a prism 1011 is filled at the rear of the reinforced slope; in order to prevent the fine particles of the filler from being lost with the groundwater, a non-woven geotextile 2007 is placed behind the gabion 1002; Concrete foundation 1005 is set at the base, concrete topping 1001 is set at the top of the reinforced slope, platforms between slopes at all levels are closed with concrete platform 1003; each layer of grid 1004 is fixed with U-shaped fixing nails 2006 after laying; filler 1007 uses Roller 2008 Layer compaction. the

The grid 1004 is a uniaxially stretched polyethylene soil grid with a unique mesh structure. Its reinforcement performance is mainly manifested in the interlocking force and embedding force between the mesh of the grid 1004 and the filler 1007. The deformation will cause the grid 1004 and the filler 1007 to have a strong interlocking and anchoring force. While generating tensile stress, the grid 1004 exerts an effect similar to lateral restraint pressure on the filler 1007, so that the filler 1007 has higher shear strength and deformation modulus. At the same time, the grid 1004 with high elastic modulus will generate vertical stress after being stressed, offsetting part of the load. In addition, under the action of vertical load, the land subsidence causes the fillers 1007 on both sides to bulge or move laterally, causing the grid 1004 to generate tensile stress, preventing the bulge or lateral movement of the filler 1007, and increasing the friction between the grid 1004 and the filler 1007 . It achieves the effect of enhancing the anti-sliding force of the reinforced slope body, thereby increasing the stability coefficient of the reinforced slope body and ensuring the safety of high and steep slopes. the

This structure ensures the stability of the high and steep slope, saves the land area, reduces the project cost, and at the same time makes better use of the spoiled earth and rocks at the project site. the
