Description
Technical field
The utility model relates to landfill leachate collection pipeline rain dirty dividing technology, the particularly switch gear of a kind of leachate collection pipeline before the subregion dam.
Background technique
The dirty shunting of the national current rain for landfill is paid much attention to, and has clearly proposed household refuse landfill sites and should carry out the dirty regulation of shunting of rain in related specifications and standard.By the understanding to domestic conventional garbage landfill yard and investigation, find that the dirty shunting of rain also belongs to weak link in the practical application of refuse landfill, this patent is exactly the technology of being innovated for the node details of the dirty shunting of refuse tip rain design and construction.
In the dirty shunting of the rain implementation process of refuse landfill; usually can take, in the landfill yard bottom, multiple tracks subregion dam is set; landfill yard is divided into to a plurality of landfills district, and bottom, landfill district arranges the leachate collection pipeline, and the leachate collection that the landfill waste zone is produced is transported to leachate equalization basin.Through the separation on subregion dam, the rainwater in landfill waste zone does not enter leachate equalization basin, is discharged into outside place.For reduce cost, what the design of most series-connection multi-partition percolate from garbage filling field collecting pipe adopted is the same collection conduit, mix for fear of rainwater and sewage, wear subregion Ba Chu at collecting pipe and need on pipeline, carry out switch designs by mounted valve, to reach the purpose of the dirty shunting of rain.
By factual survey and the understanding to the dirty shunting of a plurality of series-connection multi-partitions refuse tip rain using process, discovery wears at collecting pipe the valve that subregion Ba Chu installs, in naked state, much corrosion and the phenomenon be not closed completely all occur due to throughout the year, caused the dirty problem of mixing of rain.The valve that stainless steel or other should not corrosion material if select, investment can be very high.And valve forever is arranged on pipeline, by garbage loading embeading below, the corrosion of valve also can impact the unimpeded of pipeline.
The model utility content
The utility model provides a kind of percolate from garbage filling field collection conduit blind plate blocking device, and the valve cost of leachate collection pipeline that solve the conventional garbage landfill yard is high, and the valve place is not closed completely, and causes the dirty technical problem of mixing of rain.
The utility model solves the technological scheme that its technical problem adopts:
This percolate from garbage filling field collection conduit blind plate blocking device, comprise successively the HDPE leachate collection pipe through each landfill district and subregion dam, and HDPE leachate collection pipe is connected with the leachate collection pond outside the landfill district side slope in downstream.
Described HDPE leachate collection pipe is imperforate section at the pipeline section through the subregion dam, and the pipeline section in the landfill district is porose section; The intersection that described HDPE leachate collection pipe imperforate section and HDPE leachate collection pipe are porose section disconnects, and is reserved with pipe linear expansion spacing;
The tube head that described HDPE leachate collection pipe imperforate section and HDPE leachate collection pipe are porose section all adopts HDPE blind plate welding shutoff;
Porose section of described HDPE leachate collection pipe imperforate section and HDPE leachate collection pipe wherein on the tube head of a section cover HDPE sleeve pipe of the use that when blind plate is opened, pipeline is flexible coupling is arranged, leave between HDPE sleeve pipe and tube head and can make the spacing promoted before and after sleeve pipe.
Be equipped with the HDPE antiseepage film on the field underlayment in described subregion dam and landfill district, the HDPE antiseepage film welding of laying on HDPE leachate collection pipe imperforate section and subregion dam.
Percolate guide layer at the bottom of also being equipped with in described each landfill district.
The length of described HDPE sleeve pipe is pipe linear expansion spacing+1～2 meter.
The beneficial effects of the utility model are as follows:
Percolate from garbage filling field collecting pipe of the present utility model is divided into perforated pipe and perforated pipe not according to the position difference.Wherein wear subregion dam pipeline section for perforated pipe not, need to be welded wearing the antiseepage film of laying on subregion Ba Chu and dam body, prevent the percolate seepage; It is perforated pipe that subregion dam pipeline section is not worn in place, is convenient to collect the percolate of on-site.
The position of the utility model mounted valve on the HDPE collecting pipe, collection conduit is disconnected, utilize the HDPE pipe to belong to the HDPE blind plate performance that material of the same race can be welded, welded shutoff in the termination of two segment pipes herein with the HDPE blind plate, collection conduit is closed herein, replaced the installation of valve.While in this landfill district, there is no landfill waste, blind plate is not opened, and the rainwater that on-site is collected, can not enter the downstream leachate collection pipeline in landfill waste zone, has reached the purpose of the dirty shunting of rain; When local area starts landfill waste, blind plate is all removed and is opened herein, and the HDPE sleeve pipe of having laid is shifted onto to two segment pipe jointings, with sleeve pipe, gap reserved between two segment pipes is entangled, and prevents that foreign material from entering pipeline.By being flexible coupling of two segment pipes, make the collecting pipe UNICOM in local area and other landfill waste zone.
The utility model has been reserved the spacing of expanding with heat and contract with cold to the percolate from garbage filling field collection conduit, reduced the harm that the pipeline linear expansion causes.
The utility model provides a kind of new solution for the switch of leachate collection pipeline in the dirty shunting of refuse landfill rain implementation process, has stopped the not tight potential safety hazard of closedown of pipeline, greatly reduces construction cost, has reduced difficulty of construction.
