Embodiment 1

[0031] Such as Figure 1 to Figure 3 Shown as shown, a kind of slope support construction method, this method comprises that concrete spray surface 5 is set on the slope and retaining wall is set at the bottom of the slope, described retaining wall is a reinforced gabion, and the reinforcing bar The gabion includes a bar-shaped gabion basket 1, inside the gabion basket 1 is a filling space 3 filled with a filling layer 4, and the filling layer 4 is formed by stacking crushed stones, and the gabion basket 1 has at least one There is also a pocket net 2 fixed on the side;

[0032] The installation method of the steel gabion is as follows:

[0033] S1, install the gabion basket 1 provided with the net 2 on the slope bottom of the slope, and make the outer side of the gabion basket 1 away from the slope be the side of the gabion basket 1 fixed with the net 2;

[0034]S2 , filling gravel into the filling space 3 of the gabion basket 1 to obtain a filling layer 4 .

[0035] Speci...

Embodiment 2

[0038] Such as 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, so that the reinforced gabion can be installed in the foundation pit , the center of gravity of the reinforced gabion can be shifted to one side of the edge of the foundation pit so that the reinforced gabion can better compress the slope, and the section of the gabion basket 1 is trapezoidal. In the step S1, The reinforced gabion surface where the bottom edge of the section is located faces the slope and is installed, and the reinforced gabion surface where the upper bottom edge is located faces the center of the foundation pit. 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, so that the center of gravity of the steel bar can be used t...

Embodiment 3

[0049] This embodiment further limits this case on the basis of any one of the technical solutions provided by any one of the above embodiments. As a kind of foundation pit backfill, the steel gabion needs to be buried in the backfill soil, and the net 2 has good resistance. Corrosion ability, with the realization of ideal structural strength, the net 2 is a stainless steel wire mesh bound on the gabion basket 1.

Abstract

The invention discloses a construction method of a slope support. The method comprises the steps: arranging a concrete spray surface on a slope, and arranging a soil retaining wall at the bottom of the slope, wherein the soil retaining wall is a reinforced gabion comprising a strip-shaped gabion basket, a packing space filled with a packing layer is formed in the gabion basket, the packing layer is formed by piling gravels, at least one side of the gabion basket is also fixedly provided with a blanket net, and the mounting way of the reinforced gabion is as follows: S1, mounting the gabion basket provided with the blanket net at the bottom of the slope, and setting the outer side, far away from a slope surface, of the gabion basket to be the side, fixedly provided with the blanket net, of the gabion basket; and S2, packing the packing space of the gabion basket with the gravels to obtain the packing layer. The construction method of the slope support can be applied to a soft soil slope where the underground water level is relatively high and the soil is soaked in rainwater for a long term; a slope support structure obtained by using the construction method has an ideal drainage performance; and meanwhile, the construction method is low in construction cost, short in construction period as well as safe and reliable.

Description

technical field [0001] The invention relates to the technical field of foundation pit protection construction, in particular to a slope support construction method. 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 soil nai...
