Embodiment 1

[0052] Embodiment one: a kind of slope support structure, such as figure 1 As shown, it includes: a pile foundation assembly buried in the rock and soil layer of the slope as a supporting base; The flexible reinforced soil component 2 of the body; and the barrier component carried on the pile foundation component for preventing the flexible reinforced soil component 2 and the compacted soil layer 4 from sliding down.

[0053] Specifically, the pile foundation assembly includes: a plurality of first supporting piles 11 buried on the side of the rock and soil layer of the slope near the bottom of the slope and arranged along the extending direction of the slope; fixed between the adjacent first supporting piles 11 Between the first crown beam 12; a plurality of second support piles 13 buried in the rock and soil layer of the slope, the second support piles 13 correspond to the first support piles 11 one by one; fixed between the adjacent second support piles 13 Between the seco...

Embodiment 2

[0065] An integrated system for slope support and drainage, comprising: the slope support structure described in Embodiment 1; and a plurality of drainage pipes 5 buried in the compacted soil layer 4 and passing through the barrier assembly; specifically, A through hole is opened on the first barrier part 31, and the drain pipe 5 is plugged into the through hole and arranged obliquely downward, the inclination angle is 5-10°, 10° in this embodiment, and the drain pipe 5 adopts three-dimensional porous The flexible permeable pipe, the permeable pipe is supported by the anti-rust spring steel ring from the inside to the outside, thus forming a high-pressure-resistant soft structure. The inside of the pipe is bonded with non-woven fabric as a lining filter. The outer body is wound with polypropylene filaments, the diameter of the drain pipe 5 is 80-120 mm, and the diameter of this embodiment is 100 mm, and the water permeability coefficient is ≥ 0.02 cm / sec, so that the drain pipe...

Abstract

The invention relates to a slope supporting structure and a slope retaining and draining integrated system, wherein the slope supporting structure comprises a rock soil layer buried on a slope as a pile foundation assembly of a supporting base, a flexible reinforced soil assembly carried on the pile foundation assembly and compressed and fixed on the rock soil layer by means of a compressed rock soil layer for supporting a slope body of the slope, and a barrier assembly carried on the pile foundation assembly for preventing the flexible reinforced soil assembly and the compressed rock soil layer from sliding down. The pile foundation assembly is of relatively great rigidity and great in bending carrying capacity and anti-shear carrying capacity, can carry a relatively great load, and is small in structural deformation, so that the pile foundation assembly is of relatively high stability. The flexible reinforced soil assembly is of relatively great elasticity and toughness, can fit relatively great deformation, and is also relatively excellent in earthquake resistant behavior. In a supporting process, the pile foundation assembly is fixed on the rock soil layer and forms a stable supporting structure while the flexible reinforced soil assembly can fit the soil layer to deform adaptively, so that the slope is stably and firmly supported.

Description

technical field [0001] The invention relates to the technical field of slope support, more specifically, it relates to a slope support structure and an integrated system of slope support and drainage. Background technique [0002] With the rapid development of engineering construction and the increasing shortage of engineering land, in the development and construction of highways, railways, water conservancy, municipal and residential quarters, it is inevitable to encounter a large number of high fill vertical slopes, and usually vertical support The height is above 15m. [0003] High fill vertical slopes not only have high safety risks, but also have high construction costs. According to the "Technical Code for Building Slope Engineering" (GB50330-2013), gravity retaining walls are suitable for buildings with a height of less than 10m and no important buildings on the top of the slope. The height of the reinforced concrete buttress retaining wall should not exceed 10m; the...
