Description
Technical field
The utility model relates to a kind of pipe laying systems, specifically, can be effective when being a kind of refuse landfill sealing
The pipe laying system of draining.
Background technique
In recent years, the processing mode of China's house refuse is mostly sanitary landfills, country promulgate " house refuse health is filled out
Bury field closing technical specification " (GB 51220-2017) and " Sanitary Landfill closing technical regulation " (CJJ112-
2007) the specified in more detail covering system of refuse landfill sealing in, the refuse landfill sealing sequence row of being followed successively by from top to bottom
Gas-bearing formation, impervious barrier, drainage blanket and vegetable layer, wherein the effect of drainage blanket is that the rainwater for penetrating into upper layer is fast and effeciently discharged,
To avoid rainwater from entering the amount of increase landfill leachate in rubbish heap.Traditional drainage blanket is simple laying filler,
Resistance to water-flow is big, and water flow easily disperses to retain, and easily collecting is not discharged, and drainage effect is poor.Once there are a large amount of water to accumulate in drainage blanket and
It can not be discharged, rainwater is saturated in soil layer easily causes soil layer to come down.
Summary of the invention
Goal of the invention: the utility model patent can be drained effectively when being designed to provide a kind of refuse landfill sealing
Pipe laying system, this system can replace traditional drainage blanket, thus the rainwater etc. that quickly and efficiently discharge upper layer is penetrated into.
Technical solution:
A kind of pipe laying system of the efficient rain sewage diversion of landfill yard, including rainwater diversion layer, pipe-line system, impervious barrier,
The pipe-line system is laid on the lower section of rainwater diversion layer, and the impervious barrier is laid on the lower section of pipe-line system, pipe-line system packet
Supervisor and branch pipe are included, the landfill yard includes having acclive top and side slope, and the supervisor is along the gradient of landfill yard along slope
Parallel laid is connected to supervisor in 30 ° or 45 ° along the branch pipe of side slope, and the branch pipe at the top of landfill yard intersects company in 90 ° with supervisor
It connects, the rainwater that branch pipe is collected imports in supervisor, and supervisor is connected to landfill yard Cut-off ditch, and rainwater diversion layer includes cobble or rubble.
Further, the partial size of cobble or rubble is 40~60mm in the rainwater diversion layer, and thickness is not less than 300mm.
Further, the laying gradient of the supervisor at the top of landfill yard is 5-15 ‰, on the laying slope of landfill slope
It spends identical as landfill slope.
Further, spacing is 5~20m between the supervisor.
Further, supervisor's caliber is not less than 200mm, and branch diameter is not less than 100mm.
Further, the supervisor uses aperture floral tube with branch pipe, is surrounded by composite geotextile material outside gravel or rubble, prevents
Only rubble and particle enter in floral tube.
Further, aperture is round, strip or diamond shape.
Further, percent opening 30%~50%.
Further, the aperture of circular opening is 20~30mm.
The utility model has the advantages that the utility model can substitute the drainage blanket in existing refuse landfill sealing, mesh duct is inhaled
Water flow conductivity is strong, stronger than traditional rubble water absorbing capacity；It is in 30 ° or 45 ° along the branch pipe and supervisor of side slope, it is ensured that main
Rainwater between pipe in slope surface can obtain effectively comprehensive collect；The gradient of pipeline is 5-10 ‰, effect of the water flow in gravity
Lower direct current discharge, drainage effect is good, to overcome conventional discharge layer resistance to water-flow big, water flow easily disperses to retain, and easily collecting is not arranged
Out, the problem of drainage effect difference, is collected into rainwater with guaranteeing maximum magnitude；Supervisor uses aperture floral tube with branch pipe, can be with
Guarantee that the rainwater for flowing through supervisor and branch pipe passes through pore and carries out summarizing collection；Composite geotextile material hole is small, can stop broken
Stone particle, prevents line clogging.
Detailed description of the invention
