Problems solved by technology

However, during the construction of the gabion gabion, the gabion gabion stacked up and down is prone to misalignment, and the gabion gabion is prone to deformation, and the connection of the gabion gabion stacked up and down is poor, so it cannot form a flexible overall protection surface, making The overall structure of the retaining wall is poor, which weakens the ability to resist erosion

Embodiment Construction

[0037] Such as Figure 1 to Figure 7 Shown, be the construction method of a kind of stable gabion gabion retaining wall of the present invention, comprise the steps:

[0038] (a) Excavation of foundation pit: Excavate the foundation pit according to the construction level points on the design and construction drawings, and adopt the method of mechanical slotting and manual cleaning. During the excavation process, reserve 5-8cm at the bottom of the pit for manual cleaning, and control the slope of the bottom of the foundation pit so that it slopes 2-5% toward the shore.

[0039] Dig ditches on both sides of the bottom of the pit, slope on both sides of the ditch according to 1:2~1:3, leave a drainage ditch with a width of 10~20cm in the middle, and the setting of the ditch and drainage ditch can increase the drainage around the entire retaining wall performance.

[0040] (b) Gabion gabion production: use low-carbon zinc-coated plastic steel wires to be machine-woven into a ca...

Abstract

The invention discloses a construction method of a stable gabion stone cage retaining wall. The method comprises the following steps of (a) foundation pit excavation, (b) manufacturing of gabion stonecages, (c) gabion stone cage assembling at a foundation pit (d) mounting of a support rod, (e) mounting of a sliding rod at the bottom of a workbench, (f) mounting of the workbench, (g) hanging of asteel wire gauze, (h) stacking of the gabion stone cages from bottom to top layer by layer, (i) fixing of the gabion stone cages stacked up and down, (j) earthwork backfilling, (k) greening and (l) monitoring and measurement. Protective surfaces of the gabion stone cages stacked up and down can be located on the same inclined surface, every two gabion stone cages stacked up and down can be rapidlyand fixedly connected, a flexible integral protection surface is formed, thus, the overall structure of the retaining wall is firm, the stability is good, the retaining wall can adapt to various soillayer properties, can be combined well with soil layers and can adapt well to ground deformation, the overall structure is not weakened, fracture and damage are not prone to occurring, the water permeability is high, and the erosion resistibility is improved.

Description

technical field [0001] The invention belongs to the technical field of river regulation engineering, and in particular relates to a construction method of a stable gabion gabion retaining wall. Background technique [0002] In river regulation projects, traditional river revetments such as dry stone or concrete prefabricated blocks block the circulation of the natural ecosystem in the river because of their impermeability, and are not suitable for the concept of ecological river governance. The gabion gabion retaining wall filled with stones or pebbles in a twisted hexagonal metal mesh has the characteristics of strong erosion resistance, self-permeability, strong integrity, strong wind and wave resistance, and because it is easy for biological habitats Porous structure, with the rapid development of steel wire anti-corrosion technology, gabion gabion is more and more widely used in ecological river construction. [0003] The characteristics of the gabion gabion specificall...
