Embodiment 1

[0048] exist figure 1 , figure 2 , Figure 7 In the shown embodiment, a combined gabion anti-seepage isolation structure includes:

[0049] The gabion 1 is used for the support and load-bearing flexible box unit of pollution control or support protection projects such as trash dams and weirs; the inside of the gabion 1 is filled with filler 2; several gabions 1 are combined to form a flexible lattice bin combination isolate 3; and

[0050] In order to realize the double anti-puncture of the anti-seepage body 6, lining boards 16 can also be arranged on both sides of the anti-seepage body 6;

[0051] Inner liner 16, used for the protective body of anti-blocking packing, described inner liner 16 is arranged at the opening of two horizontally split gabion bodies and forms an insertion channel 5 between the two gabion bodies; and

[0052] The anti-seepage body 6 is inserted inside the insertion channel 5 formed by the buffer grid 4 and extends up and down at both ends to form ...

Embodiment 2

[0066] exist image 3 In the shown embodiment, its structure is basically the same as that of Embodiment 1, the difference is that it is suitable for higher engineering conditions, and according to the height requirements of the project, the combined gabion anti-seepage isolation structure of the present invention is carried out on site. On-site assembly, first, insert the anti-seepage body into the bottom of the warehouse, and unwind upwards, then combine the gabion 1, and combine the gabions in a single group in the horizontal direction at the unwinding position of the anti-seepage body, take two Only large-scale gabion body 1 with inclined angled bottom surface is provided with lining plate 16 respectively at the opening of gabion body, and buffer grid 4 is set inside gabion body 1 near liner plate 16, and buffer lattice The six faces of the grid are provided with isolation bags 43, and the inside of the isolation bags 43 is filled with anti-permeable air sand, stone powder...

Embodiment 3

[0068] exist Figure 4 In the shown embodiment, its structure is basically the same as that of Embodiment 1, the difference is that it is suitable for the engineering working conditions of realizing the anti-seepage isolation on both sides inside the blocked body, and according to the requirements of the engineering height, the combination of the present invention on site On-site assembly of the type gabion anti-seepage isolation structure. First, insert the anti-seepage body into the impermeable layer at the bottom of the reservoir, and unwind upwards, then combine the gabion 1, and align the gabion at the unwinding position of the anti-seepage body Carry out a single-group combination in the horizontal direction, take two gabion bodies 1 that are equal in size and have an inclined bottom surface, and set lining boards 16 at the openings of the gabion bodies respectively, and close to the lining board 16 The inside of the gabion 1 is provided with a buffer grid 4, and isolati...

Abstract

The invention discloses a combined gabion anti-seepage isolation structure. The combined gabion anti-seepage isolation structure comprises gabion bodies, anti-seepage bodies and buffer grids, whereinthe gabion bodies are used for supporting and bearing flexible box units in pollution control or retaining protective engineering of waste barrages, weir bodies, anti-seepage isolation walls and the like; the gabion bodies are filled with fillers; the plurality of gabion bodies are combined to form a flexible gabion combination isolation body; insertion channels are formed at the openings of everytwo horizontally-spliced gabion bodies; the anti-seepage bodies are inserted into the insertion channels formed by the buffer grids, and extend to the upper end and the lower end to form an anti-seepage main body of a waterproof geological unit; and the buffer grids are arranged inside the gabion bodies and close to the insertion channels, and are used for preventing the fillers from piercing buffer anti-seepage bodies of the anti-seepage bodies. The invention further discloses a construction method for the combined gabion anti-seepage isolation structure. The anti-seepage bodies are connected with engineering bottom or top anti-seepage layers to form the waterproof geological unit, so that the integrity and continuity of the anti-seepage system of the entire reservoir area are realized,and the anti-seepage safety of the entire reservoir area is improved.

Description

technical field [0001] The invention relates to the technical fields of environmental protection engineering, water conservancy engineering and municipal engineering, in particular to a combined gabion anti-seepage isolation structure and a construction method thereof. Background technique [0002] In environmental protection projects, water conservancy projects, and municipal engineering, it is often necessary to set up anti-seepage isolation structures to prevent liquid leakage. In particular, environmental protection projects must intercept leachate in sewage or solid waste to prevent pollution of the surrounding environment. The requirements for anti-seepage relatively high. The more common way to isolate the structure is to use the retaining wall or dam body as the support structure, and set the anti-seepage body on the support structure. There are two ways to install the anti-seepage body. One is to install it on the facing surface of the support structure, which adop...
