Description
Technical field
The utility model belongs to garbage loading embeading facility field, is specifically related to a kind of refuse landfill air guide gabion and collects well.
Background technology
The structures such as it is different that well form collected by refuse landfill air guide gabion of the prior art, percolate discharge guiding pipe at the bottom of the field that the crushed rock filler that air guide gabion collection well generally comprises the air guide floral tube of insertion in the middle of column iron wire grid, iron wire grid, iron wire grid inside is filled of main flow, air guide floral tube lower end are fixedly connected with.This kind of air guide gabion is collected well and mainly be there is following defect:
1. fill the crushed rock filler no matter granular size of iron wire grid, mixing is inserted in iron wire grid completely, in actual operation process, there is gap between the rubble of local excessive, the filtration that rubbish or mud can not be orderly in crushed rock filler, thus causes air guide floral tube to block.
2. air guide floral tube is directly connected with percolate discharge guiding pipe at the bottom of field, execute man-hour requirement at the bottom of field percolate discharge guiding pipe upper shed then with the sweat soldering of air guide floral tube, add difficulty of construction undoubtedly, there is the insecure risk of quality brought because of construction technology difference in work progress, on percolate discharge guiding pipe at the bottom of field, perforate also impacts the life-span of discharge guiding pipe itself undoubtedly.
In addition, because air guide floral tube is directly connected with discharge guiding pipe, filter and not exclusively cause dirt may enter discharge guiding pipe from air guide floral tube, thus cause discharge guiding pipe to block, lose its function.
3. argillic horizon of the prior art is generally the structure of tiling at wireway and neighboring area thereof, and thickness of clay soil is limited, and gabion region can not be made to have good sealing, and portion gas can be caused excessive.
Utility model content
For the problems referred to above, the utility model aims to provide one can prevent percolate discharge guiding pipe blocking at the bottom of air guide floral tube and field, gas guide good airproof performance, and difficulty of construction is low, and well collected by the refuse landfill air guide gabion of reliable construction quality.
The technical scheme that the utility model is dealt with problems is: well collected by a kind of refuse landfill air guide gabion, comprise the iron wire grid vertically arranged, iron wire grid center vertical is provided with air guide floral tube, bottom of the reservior percolate rubble guide layer is provided with, percolate discharge guiding pipe at the bottom of being embedded with in this bottom of the reservior percolate rubble guide layer below iron wire grid; Be provided with overburden layer in the middle of end above iron wire grid, be provided with closing rubble exhaust level above overburden layer in the middle of end, be equipped with graded broken stone between air guide floral tube and iron wire grid, and the grade of graded broken stone reduce to air guide floral tube direction gradually along iron wire grid;
The height of air guide floral tube extends to closing rubble exhaust level bottom iron wire grid;
Be provided with closing argillic horizon above closing rubble exhaust level, air guide floral tube upper end is connected with air guide pipe in fact, and the real pipe of this air guide communicates with ambient atmosphere through closing argillic horizon, and the real pipe exposure of air guide height is in an atmosphere all the time higher than the height of heap body after closing.
Further, there is gap at the bottom of described field between percolate discharge guiding pipe and air guide floral tube, namely the two is not directly connected.
Preferably, described wire netting especially surface coverage have geotextiles.
Further, the cross sectional shape being positioned at the closing argillic horizon in the real territory, area under control of air guide is inverse-T-shaped, it comprises tiling part and vertical portion, tiling part is for being laid on the horizontal argillic horizon in closing rubble exhaust level, and vertical portion is be positioned at the real territory, area under control of air guide and lay the argillic horizon to earth's surface along the real pipe of air guide always.
The tiling upper of described closing argillic horizon is provided with closing rubble drainage blanket, overlying soil, closing nutrition soil layer and vegetable layer successively.
Remarkable result of the present utility model is:
1. the rubble of filling iron wire grid is graded broken stone, and rubble is laid according to granular size classification, reduces gradually from iron wire grid to air guide floral tube direction, make the filtration that rubbish or mud can be orderly in crushed rock filler, gap uniformity between rubble and rubble, can prevent air guide floral tube from blocking.
2. air guide floral tube is not directly connected with percolate discharge guiding pipe at the bottom of field, but there is certain distance, and the percolate in air guide floral tube flows into discharge guiding pipe after bottom of the reservior percolate rubble guide layer filters further, avoids discharge guiding pipe blocking.
Such design reduces difficulty of construction while being not affect discharge opeing, and without the need to carrying out the welding between tube and tube, the life-span of discharge guiding pipe self is unaffected, does not also have construction risk.
3. wire netting periphery covers geotextiles, prevents rubbish from entering, serve the effect of primary filter while permission percolate enters.
4. because the gas of guide mostly concentrates on air guide gabion region, be designed to inverse-T-shaped by the argillic horizon in air guide gabion region, the area thickness that guide gas is comparatively concentrated increases, and makes the gas of guide have better sealing, gas can not be caused excessive.
