Description
Technical field
The present invention relates to environmental improvements such as household garbage, industrial solid wastes, hazardous waste, soil pollution and petrochemical industry, hydrotechnics field, especially relate to mounting method based on the vertical flexible barrier system of native stone ground.
Background technology
Along with rapid economic development, industrialization and quickening of urbanization process; Generations such as domestic waste, industry are useless admittedly sharply increase; The soil in the original urbanization work area after the resettlement utilizes gradually and increases; And people are increasingly high for the requirement of dwelling environment, and the anti-seepage effect in still present solid waste landfill site, dump leaching field, mine, high-concentration waste water pond etc. is unsatisfactory.China's seepage control technique development has simple and easy yard of some rubbish and nonstandard refuse landfill to pollute seepage than later.Certainly, also have some requirement of engineering to stop that underground liquid comprises that the lateral transfer of liquid such as fresh water, salt solution prevents to destroy engineering and construction.
Summary of the invention
The purpose of this invention is to provide mounting method, so that address the above problem based on the vertical flexible barrier system of native stone ground.
In order to realize the foregoing invention purpose, the technical scheme that the present invention adopts is following:
A kind of mounting method of the vertical flexible barrier system based on native stone ground comprises the steps:
The first step is excavated the ditch be used to install said vertical flexible barrier system;
In second step,, form the retaining wall topping to recharging impervious mud in the said ditch;
In the 3rd step, utilize supporting tool that the HDPE geomembrane is installed to and form HDPE geomembrane wall in the said ditch;
The 4th step, the chemical grouting sealing is carried out in the bottom of said HDPE geomembrane wall, form the bottom seals layer;
The 5th step, withdraw from said supporting tool, form said vertical flexible barrier system.
The width of said ditch is 0.8～1.2m, and the degree of depth of said ditch is excavated 1.5～2m after will excavating natural impervious barrier again.
In the degree of depth of the said ditch of distance the top 1.5m, excavate width to the 3.2～3.6m of said ditch again.
In the said first step, in the process of excavating said ditch, to recharge impervious mud while excavating, guarantee to be full of at any time in the said ditch impervious mud.
In said second step; The right ends of said HDPE geomembrane is provided with the connection latch fitting; First said HDPE geomembrane supported with said supporting tool directly be placed in the said ditch and fix, the expansion waterstop pad is compressed into the cavity on the said connection latch fitting of this said HDPE geomembrane; Support and make the said cavity on cavity and said first on the said connection latch fitting on it to align with said supporting tool second said HDPE geomembrane again; Then said second said HDPE geomembrane inserted in the said ditch; Simultaneously the said cavity on said second said HDPE geomembrane realizes working in coordination installation with the said cavity on said first, and said expansion waterstop pad is positioned at the interlocking sealing device that cavity formation that the said cavity on said second said HDPE geomembrane becomes with said cavity cover on said first comprises said expansion waterstop pad; When the said HDPE geomembrane of N piece is installed, by that analogy.
Said connection latch fitting comprises T font structure vertical with the interarea of said HDPE geomembrane and inverted L shape structure; Said T font structure is installed near the edge of said HDPE geomembrane, and said inverted L shape structure is positioned at that said T font structure is installed away from a side at the edge of said HDPE geomembrane and the direction of the crotch of said inverted L shape structure is pointed to said T font structure.
In said the 4th step; The said chemical grouting of solidifying under the uniform discharge water of chemical grouting device mesohigh that is provided with in advance from the bottom of said HDPE film wall; The height of the said chemical grouting of discharging is 1.0～2.0m, treats to form said bottom seals layer after said chemical grouting is solidified.
Said supporting tool is a stainless steel strut, and said stainless steel strut is provided with the fastening devices of fixing said HDPE geomembrane.
The present invention relates to be used for comprehensive shutoff and intercept refuse landfill and ooze drop liquid pool, industry and hazardous waste, oil, chemical plant, Coal Chemical Industry, mining industry, toxic gas etc., even also comprise a kind of a kind of mounting method of needs excavation of high-density polyethylene geomembrane leakage preventing structure of pollution sources lateral transfer polluted underground water and the soil resource of wetland and hydraulic engineering.
Mounting method of the present invention is fit to various soil environments, is applicable to following field: 1. field of environment protection: the collection of hazardous waste and obstruct, protection underground water source etc.; 2. wetland field: the protection of environment and construction etc.; 3. building field: lower destruction that Groundwater Flow possibly cause, build flood control dyke, allow in digging process draining etc.
The construction equipment that the present invention needs comprises:
