Embodiment 1

[0026] like Figure 1 to Figure 3 As shown, a reinforced gabion slope support structure includes a reinforced gabion, and the reinforced gabion includes a strip-shaped gabion basket 1, and the inside of the gabion basket 1 is a filling space filled with a filling layer 4 3. The filling layer 4 is made of crushed stones, and a net 2 is fixed on at least one side of the gabion basket 1 .

[0027] Specifically, although the prestressed anchor composite soil nail wall has been widely used as the support, reinforcement and protection measures of the foundation pit, in practice, the prestressed anchor composite soil nail wall is more suitable for the non-water level above the groundwater level or after precipitation. For soft soil foundation pits, when the groundwater level is high or the foundation pit is soft soil despite the precipitation measures, the prestressed anchor bolts will gradually fail, the concrete sprayed surface may collapse, and there is a risk of slope collapse. ...

Embodiment 2

[0031] like Figure 1 to Figure 3 As shown, this embodiment is further limited on the basis of Embodiment 1: as mentioned above, the reinforced gabion can be used as a gravity retaining wall in the supporting structure. After the reinforced gabion is installed in the foundation pit, the steel bar The center of gravity of the gabion can be shifted to one side of the edge of the foundation pit so that the steel gabion can better compress the slope, and the section of the gabion basket 1 is trapezoidal. As those skilled in the art, the trapezoidal structure includes two bases and two sides, wherein the longer base is the lower base, and the shorter base is the upper base. The reinforced gabion face is installed facing the side slope, and the reinforced gabion face where the lower bottom is located faces the center of the foundation pit, so that the center of gravity of the reinforced gabion can be shifted toward one side of the slope.

[0032] As a specific implementation of the...

Embodiment 3

[0037] This embodiment further limits this case on the basis of the technical solution provided in embodiment 2, as image 3 As shown, as an implementation form of a support structure with strong soil retaining ability, it also includes a concrete spray surface 5 arranged on the slope, and the upper bottom of the gabion basket 1 leans against the concrete spray surface 5 .

[0038] In order to improve the structural stability of the concrete sprayed surface 5 on the slope, the steel gabion serves as the bottom support of the concrete sprayed surface 5 .

[0039] In order to form an underdrain with a large flow rate or to make the reinforced gabion have better soil-retaining performance, there are multiple reinforced gabions, and the reinforced gabion is stacked on the bottom of the concrete spray surface 5 .

[0040] In order to improve the structural strength of the concrete surface, the concrete sprayed surface 5 is also built with a reinforcement mesh.

[0041] In order to...

Abstract

The invention discloses a rebar gabion slope supporting structure. The structure comprises rebar gabions, wherein the rebar gabions comprise strip-shaped gabions; filling spaces filled with filling layers are formed in the gabions; the filling layers are formed by piling up crushed stones; and blanket nets are fixed on at least one sides of the gabions. The slope supporting structure can be applied to soft soil side slopes where the underground water level is high and the soil is soaked by rain water for a long time; the slope supporting structure has an ideal drainage performance; and meanwhile, the structure is low in construction cost, short in construction period, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of foundation pit protection construction, in particular to a reinforced gabion slope support structure. Background technique [0002] The foundation pit support is to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit, and the support, reinforcement and protection measures are adopted for the side wall of the foundation pit and the surrounding environment. Common foundation pit support structure types mainly include: retaining structure, soil nail wall, gravity cement-soil wall, grading, etc. Composite soil nail wall support has the characteristics of light weight, flexible maneuverability, wide application range, low cost, short construction period, safety and reliability, strong support capacity, can be used as advanced support, and has the effects of support and water interception. In the prior art, for example, prestressed anchor composite ...
