Abstract
The utility model relates to a landfill gas collection well based on a gas guide stone cage. The landfill gas collection well based on the gas guide stone cage comprises a gas collection pipe and a movable well head, wherein the movable well head is fixedly connected with the gas collection pipe, a sealing tray is arranged on the top of the movable well head, a gas exhausting pipe is arranged on the lateral wall of the movable well head, the gas exhausting pipe is connected with a valve, and the gas collection pipe is fixed on the inner side wall of a stone cage floral pipe. A sealing layer is arranged between the gas collection pipe and the stone cage floral pipe, and a penetrating fluid draining pipe and a high-pressure air inlet pipe begin from the bottom of the stone cage floral pipe, penetrate through the interior of the gas collection pipe upwards, are communicated with the sealing tray of the movable well head, and stretch into the air. The landfill gas collection well based on the gas guide stone cage has the advantages of being simple in construction craft, reducing construction intensity and construction period, greatly improving speed of building a landfill gas collection well, and being mature in construction craft, strong in environment adaptability, and good in gas collection effect. An original existing gas guide stone cage is utilized to rapidly form a well. The penetrating fluid draining pipe is additionally arranged, percolate is convenient to exhaust, and cost of maintenance is greatly reduced.
Description
Technical field
The utility model relates to a kind of for refuse landfill gas collection well, a kind of landfill-gas collecting well based on the air guide gabion of special design.
Background technology
Refuse landfill in China, assemble in the heap body for the landfill gas that prevents from producing in the junk-heap body, consist of hidden peril of explosion, common way is in garbage loading embeading, in the heap body, build many landfill gas guide gabions, allow being discharged in the atmosphere of the landfill gas nature that produces in the rubbish.Because this part guide gabion technique is relatively simple, advance easily oxygen, be not suitable for doing the collection well of utilization of LFG, so way in the past is that it is abandoned burying, again inflates body at junk-heap body and collect well, so just cause the waste of this part facility.How to effectively utilize the guide gabion and collect landfill gas, be the problem that we are concerned about always.
Application number is that 201120171061.6 patent has been announced a kind of movable well head for vertical collecting well, but this patent also is again to dig a well to install on rubbish heap, and workload is large, and it is also higher to implement cost.
Summary of the invention
The utility model proposes a kind of landfill-gas collecting well based on the air guide gabion for the problem that prior art exists.
The technical solution of the utility model is:
A kind of landfill-gas collecting well based on the air guide gabion, comprise gas collecting pipe, movable well head, wherein movable well head is fixedly connected with the gas collection tube, the top of movable well head is provided with seal disc, the sidewall of movable well head is provided with exhaust tube, be connected with valve on the exhaust tube, the gas collecting pipe is fixed on gabion floral tube madial wall, be provided with sealant between gas collecting pipe and the gabion floral tube, penetrating fluid drainpipe and pressure-air air inlet pipe start from the bottom of gabion floral tube, be upward through the inside of gas collecting pipe and run through the seal disc of movable well head, extend in the air.
Described landfill-gas collecting well based on the air guide gabion, the lower end of described gas collecting pipe is lower than sealant bottom.
Described landfill-gas collecting well based on the air guide gabion, the material of described sealant are plastic sheeting and fine sand.
Described landfill-gas collecting well based on the air guide gabion is laid overburden layer at the topmost of sealant and gabion floral tube.
The beneficial effects of the utility model are: 1. the utility model construction technology simple, utilize original already present air guide gabion quick well formation, reduce construction intensity and construction period, greatly improve the speed of setting up landfill-gas collecting well.
2. the utility model is based on original air guide gabion, and construction technology is ripe, and environmental suitability is strong, gas collection is effective, is provided with in addition the penetrating fluid drainpipe, makes things convenient for percolate to discharge, and greatly reduces the expense of maintenance.
3. the utility model belongs to based on air guide gabion well, and movable well head and air guide gabion all can reuse, reduce the environmental pollution that the solid waste gas dissipation that brings of again driving a well causes, and has the advantage that reduces rubbish landfill gas dissipation.
Description of drawings
Fig. 1 is side of the present utility model sectional structure schematic diagram;
Among the figure: 1 is the gas collecting pipe, and 2 is sealant, and 3 is exhaust tube, and 4 is overburden layer, and 5 is valve, and 6 is the penetrating fluid drainpipe, and 7 is the pressure-air air inlet pipe, and 8 is the gabion floral tube, and 9 is cobblestone, and 10 is movable well head, and 11 is seal disc.
The specific embodiment
Embodiment 1: in conjunction with Fig. 1, a kind of landfill-gas collecting well based on the air guide gabion, comprise the gas collecting pipe, movable well head, wherein movable well head is fixedly connected with the gas collection tube, the top of movable well head is provided with seal disc, the sidewall of movable well head is provided with exhaust tube, be connected with valve on the exhaust tube, the gas collecting pipe is fixed on gabion floral tube madial wall, be provided with sealant between gas collecting pipe and the gabion floral tube, penetrating fluid drainpipe and pressure-air air inlet pipe start from the bottom of gabion floral tube, are upward through the inside of gas collecting pipe and run through the seal disc of movable well head, extend in the air.
The lower end of described gas collecting pipe is lower than sealant bottom; The material of described sealant is plastic sheeting;
Topmost at sealant and gabion floral tube is laid overburden layer.
Work progress: excavate lower 50-60cm rubbish or the clay, radius 1.8-2m of digging by the collection well construction requirement with around the air guide gabion.Cut air guide gabion reinforcing bar, remove cobblestone, in the hole of excavation, bury and fill clay and compacting.On request plastic sheeting is fixed on the gas collecting tube-surface; The gas collecting pipe of making is inserted in the air guide gabion floral tube.
