Description
Technical field
The utility model relates to a kind of second class storage, disposal site seepage control system and draining shaft bridging arrangements, are suitable for
The second class storage containing this class formation, disposal site, may extend to household refuse landfill sites, hazardous waste security landfill disposal site
Etc. engineerings.
Background technique
In recent years, the second class industrial solid wastes yield is increasing, and brought environmental problem also becomes increasingly conspicuous.Especially
If being that percolate that harmful substance in waste residue occurs after rainwater leaching leaching cannot be effectively treated will be to surrounding enviroment and ground
It is lauched and causes greatly to pollute.Currently, national environmental protection authorities have put into effect corresponding laws and regulations and Regulations, it is desirable that second
Class industrial solid wastes must be provided with seepage control system and flood drainage system.
The storage of second class general industry solid waste, disposal site reservoir area seepage control system generally use single layer HDPE geomembrane conduct
Main impervious material, when using draining shaft as flood discharge facility in library, the rank of geomembrane and draining shaft concrete structure
It connects as antiseepage weak spot, easily generation leakage of leachate accident.Currently, the overlap joint of geomembrane and draining shaft mostly use it is single
Lap joint form will cause seepage control system when geomembrane welding quality is bad or sedimentation occurs for draining shaft leads to weld seam drawing crack
Destruction, and repair difficulty it is very big, so as to cause environmental pollution accident；Draining shaft stores as the second class, disposal site place
One of key facility to drain off floodwaters inevitably has overlap joint with seepage control system in the construction process.Seepage control system and draining shaft clinch
Weak link of the position as the storage of the second class, disposal site antiseepage if mishandling is easy to that percolate leakage pollution week occurs
Surrounding environment and underground water.
The bridging arrangement of existing seepage control system and draining shaft is mainly by anchoring groove connection, directly by antiseepage film anchor
Gu connecting three kinds in concrete blocks and through connection lock.The specific practice connected by anchoring groove are as follows:
1. the groove with annular edge is arranged on draining shaft；
2. the bed course in Construction Anti-seepage system, bed course top is concordant with annular edge；
3. being laid with antiseepage film, antiseepage film need to go deep into groove；
4. the casting concrete on groove, concrete top are concordant with annular edge；
5. being laid with clay protective layer in antiseepage film.

Certain distance is increased up to the draining shaft borehole wall and along the borehole wall 1. being laid with seepage control system；
2. carrying out seepage control system anchoring in draining shaft borehole wall casting concrete briquetting.
Pass through the specific practice of connection lock connection are as follows:
1. the pre-buried twice connection lock when draining shaft pours；
2. being laid with seepage control system until first of the connection of the draining shaft borehole wall is locked, and main antiseepage film is welded on first of company
It connects and locks；
It is locked 3. antiseepage film one end will be reinforced and be welded on second connection, the other end and main antiseepage film are welded, to antiseepage system
System carries out local strengthening.
The bridging arrangement of existing seepage control system and draining shaft cannot avoid leakage preventing structure due to discontinuity completely
Or the possibility that tearing causes antiseepage leakage of leachate occurs for the reasons such as stress is excessive, needs to take new method to seepage control system and row
The bridging arrangement of water vertical shaft improves.
Utility model content
