Description
Technical field
The utility model relates to garbage loading embeading field device field, particularly a kind of anti-floating evacuation system for refuse landfill.
Background technology
The evacuation system of refuse landfill regulating reservoir, comprise exhaust pipe, as shown in Figure 1, the refuse landfill regulating reservoir of prior art is outdoor structure, exhaust pipe is perforation HDPE pipe (high density polyethylene pipe), and exhaust pipe is placed on impervious barrier, and HDPE pipe density ratio water is little can float in water, therefore need at the exhaust pipe at slope place, many places cranse is set, and in bottom, pond by concrete pier come ballast fix HDPE pipe.In order to prevent solid refuse from entering exhaust pipe, blocking exhaust pipe, the pump drainage mercury that impact is placed in exhaust pipe runs, and makes evacuation system cisco unity malfunction, and the aperture of perforation HDPE pipe can arrange smaller, and blind plate shutoff can be used in the end of exhaust pipe.But because aperture is smaller, be generally 20mm ~ 25mm, the discharge of sewage is lower, especially after some time of use, eyelet is easy to fouling, long mycelia or mud accumulation thus blocking inlet opening.After the blocking of inlet opening, the discharge of sewage can be caused to lower further, when making pump drainage mercury pump drainage, the outer sewage supply of pipe is too late and can form cavity in exhaust pipe, produce huge buoyancy, when the buoyancy that cavity produces exceedes the restraint forces of concrete ballast weight and cranse, exhaust pipe causes evacuation system to lose efficacy by floating and cause antiseepage film to destroy.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of anti-floating evacuation system for refuse landfill, and this evacuation system can keep exhaust pipe eyelet to circulate smoothly in Long-Time Service, prevents the floating evacuation system that makes of exhaust pipe to lose efficacy.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of anti-floating evacuation system for refuse landfill, comprise exhaust pipe to be all closed with the oilysewage surface regulating reservoir with the floating head film covered on regulating reservoir, described floating head film edge is fixed on outside regulating reservoir; Described exhaust pipe end is uncovered structure, described exhaust pipe has multiple large scale inlet opening, and described large scale inlet opening diameter is D, wherein D >=80mm; Be lined with one deck non-woven geotextile on described regulating reservoir impermeable layer on pond bottom upper berth, described non-woven geotextile has been built concrete foundation layer, the pipeline section that described exhaust pipe is positioned at the bottom of regulating reservoir pond is provided with the cranse of concrete foundation layer anchoring with fixing exhaust pipe.
Further, described floating head film be by HDPE diaphragm be welded entirety, close cover on the whole sewage regulating reservoir water surface.
Further, described large scale inlet opening diameter is D, wherein D=100mm.
Further, described concrete foundation layer thickness is preferably 150mm.
Compared with prior art, the utility model prevents that floating evacuation system avoids solid refuse to enter regulating reservoir by sewage surface on regulating reservoir covering floating head film, ensure that can not be circulated smoothly by solid refuse blocking in inlet opening; And by arranging large scale inlet opening on exhaust pipe, exhaust pipe end is that uncovered structure is to expand the discharge of sewage, and large scale inlet opening is not easy fouling, long mycelia or has mud to pile up, such guarantee sewage is in liberal supply and can not form cavity in exhaust pipe, thus avoid producing huge buoyancy and cause exhaust pipe floating, cause evacuation system to lose efficacy and destroy antiseepage film.
Accompanying drawing explanation
Fig. 1 is the structural representation of the evacuation system of prior art.
Fig. 2 is the structural representation that the utility model prevents floating evacuation system.
Detailed description of the invention
As shown in Figure 2, a kind of anti-floating evacuation system for refuse landfill, the pump drainage mercury comprising exhaust pipe 1 and be placed in exhaust pipe 1.Regulating reservoir is also coated with floating head film 5, floating head film 5 be by HDPE diaphragm be welded entirety, close to cover on the whole sewage regulating reservoir water surface, can with the floating head film 5 of dirty SEA LEVEL VARIATION fluctuation, floating head film 5 edge is fixed on outside regulating reservoir, and described floating head film 5 can be fixed by anchor device and seal.By arranging the floating head film 5 covered on the regulating reservoir water surface, effectively can stop that solid refuse enters in regulating reservoir, can also prevent the diffusion of sewage foul smell and grow mosquitos and flies.
Described anchor device comprises steel plate, expansion bolt and concrete ballast, floating head film 5 edge stretches out regulating reservoir and is laid on regulating reservoir outward flange platform, steel plate is pressed in described floating head film 5 upper surface, expansion bolt is squeezed in platform through steel plate and floating head film 5, and the concrete ballast that platform is provided with cast is pressed on described floating head film 5, steel plate and expansion bolt.
Entering the speed of exhaust pipe 1 in order to improve sewage, avoiding because sewage supply is too late and cavity can be formed in exhaust pipe 1, producing huge buoyancy, described exhaust pipe 1 end is uncovered structure 13, exhaust pipe 1 adopts large scale inlet opening 12, and described large scale inlet opening 12 diameter is D, wherein D >=80mm.Preferred version is, D=100mm.Due to the regulating reservoir water surface being coated with floating head film 5, therefore do not need to worry that solid refuse blocks exhaust pipe 1.
Garbage leachate directly can enter pipeline from the end of exhaust pipe 1 or large scale inlet opening 12, so just greatly can improve the discharge of sewage, large scale inlet opening 12 also can effectively be avoided using perforations fouling, long mycelia or mud to pile up thus this situation of blocking inlet opening long-time, thus ensure that sewage is in liberal supply, cavity can not be formed in exhaust pipe 1 and cause exhaust pipe 1 floating.And when pump drainage mercury stops pumping because of Action of Gravity Field, the sewage of backflow then to wash away bottom exhaust pipe 1 thus to take the mud of deposition out of, effectively prevent space in the exhaust pipe 1 that causes because mud deposits gradually and reduce, ensure the running space of pump drainage mercury.
Because exhaust pipe 1 adopts HDPE to manage, this material density ratio water is low, therefore needs to adopt correspondingly fixation.In order to prevent, side slope antiseepage film be damaged simultaneously, side slope not adopt any fixation to exhaust pipe 1, and at the pipeline section that exhaust pipe 1 is positioned at the bottom of regulating reservoir pond, it being fixed.In order to prevent fixation from damaging regulating reservoir impermeable layer on pond bottom 2, be lined with one deck non-woven geotextile 3 on described regulating reservoir impermeable layer on pond bottom 2 upper berth.Described non-woven geotextile 3 has built concrete foundation layer 4, and exhaust pipe 1 pipeline section be positioned at the bottom of regulating reservoir pond is provided with cranse 14, and this cranse 14 and concrete foundation layer 4 anchoring are with fixing exhaust pipe 1.Concrete foundation layer 4 thickness is preferably 150mm.
