Embodiment 1

[0040] A certain slope is located in Xianning Mountain, Hubei Province. The site is a fill and excavation area, and the geological environment of the site is a relatively stable area. Large-area filling and small-area excavation shall be carried out on the site at the existing location. The filling height shall be about 15-18m, and a high-voltage electric tower shall be built on the soil layer where the filling reaches the design height. Due to the importance of the slope, according to the above-mentioned project overview, combined with regional experience, and in accordance with the design principles of safety and economy, this project adopts the pile-supported reinforced soil combined retaining structure design scheme. Geogrid reinforced soil structure with two-stage filling, such as figure 2 As shown, the total height of the filling is 14.5m, of which, from bottom to top, the height of the first-level reinforced soil fill slope is 7.5m, and the height of the second-level r...

Abstract

The invention belongs to the field of slope support and relates to a pile-penetration filling body reinforcing load-bearing structure and a construction method thereof. The structure comprises a reinforced soil replacement treating area arranged at a toe of a slope original terrain line, a filling body arranged on the upper surface of the reinforced soil replacement treating area and a prefabricated antiskid pile arranged at a top of the slope original terrain line and driven into or pressed into a slope from the upper surface of the filling body, and each of the reinforced soil replacement treating area and the filling body comprises a geosynthetic material in layered arrangement and compacted filling which is filled in the geosynthetic material and compacted. The structure can effectively improve integrity of filling soil and prevent landslide and can bear large upper load.

Description

technical field [0001] The invention belongs to the field of slope support, and relates to a reinforced load-bearing structure and a construction method, in particular to a reinforced load-bearing structure and a construction method of a pile penetration type filling body, which can improve the integrity and stability of the fill body. Stability, effectively preventing the slope from slipping, and a joint support structure that can bear a large upper load, is mainly used for the stability control of the adjacent filling body of the upper load-bearing slope. Background technique [0002] With the development of economic construction, the natural environmental conditions of engineering construction are becoming more and more complex. When carrying out mountain construction and building construction, the problem of high fill is often encountered. Due to the constraints of terrain and other conditions, high fill is usually adjacent to high excavation, especially when soil fillin...
