Description

Sunk cone well pile for construction of biogas collection well of refuse landfill

Technical Field

The utility model mainly relates to the technical field of landfill treatment, in particular to a sunk cone well pile for construction of a methane collection well of a landfill.

Background

The landfill is still the most main method for solving the domestic garbage to go out in most cities in China, 356 domestic garbage landfill sites are provided in the whole country at the end of 2005, and 85% of the domestic garbage is subjected to landfill treatment. The landfill technology has the characteristics of simple operation and capability of treating all kinds of garbage.

A large amount of building and domestic garbage are piled in a garbage landfill site, and waste plant roots or putrefying organisms contained in the garbage are piled for a long time, the interior of the garbage becomes an anoxic state because of being isolated from air, and at the moment, the internal substances are decomposed by microorganisms to form methane. If the biogas is not treated, the biogas can bring about huge harm, not only is hidden danger of fire and explosion, but also can be diffused to damage the health of people, and can generate greenhouse effect when being discharged into the atmosphere.

SUMMERY OF THE UTILITY MODEL

In view of the defects in the prior art, the utility model provides a sunk cone well pile for construction of a landfill marsh gas collecting well.

In order to solve the technical problem, the utility model discloses a following technical scheme: the utility model provides a landfill marsh gas is collected well construction and is used countersink well stake which characterized in that: the pile comprises a pile cover, a pile barrel and a pile head, wherein the pile barrel is in a hollow tubular shape, one end of a support is connected with an annular partition plate, the other end of the support is connected with a central shaft, a net rack body is arranged between the annular partition plate and the central shaft, an air inlet hole is arranged on the net rack body, a filter screen is arranged in the net rack body, and a quartz stone interlayer is filled between the net rack body and the filter screen.

As a further improvement of the utility model, the diameter of the bottom surface of the pile head is slightly larger than the diameter of the section of the pile cylinder and is used for being connected with one end of the pile cylinder; the outer diameter of the pile cover is slightly larger than the outer diameter of the pile cylinder and is used for covering the other end of the pile cylinder.

As a further improvement of the utility model, the pile head is a cone, and a spiral sheet is arranged on the cone.

As a further improvement of the utility model, the top of the pile barrel is provided with a lifting ring or a hook for connecting the lifting device to lift the pile barrel from the landfill.

Compared with the prior art, the utility model discloses the beneficial effect who has does: the pile barrel collects methane under a garbage landfill site, the quartz stone interlayer is filled between the net rack body and the filter screen, so that the gas outlet is smooth, the porous collecting pipe is effectively prevented from being buried by percolate, the annular clapboard can separate the garbage layer, so that the gas inlet hole on the net rack body is smooth, and the methane enters the methane treatment system through the pile cover under the action of an external exhaust fan after passing through the hollow pipe at the central shaft of the pile barrel.

Drawings

The invention will be further described with reference to the accompanying drawings and specific embodiments:

FIG. 1 is a schematic structural view of a sunk cone well pile for construction of a biogas collection well of a refuse landfill;

fig. 2 is a plan view of the utility model of a sunk cone well pile for the construction of a marsh gas collecting well of a refuse landfill.

In the figure: 1 pile cover, 2 pile barrels, 3 pile heads, 4 air outlet pipes, 5 annular partition plates, 6 net frame bodies, 7 air inlet holes, 8 quartz stone interlayer, 9 filter screens, 10 central shafts and 11 spiral sheets.

Detailed Description

In order to make the technical solution and the advantages of the present invention more clear and obvious, the present invention is further described in detail with reference to the following specific embodiments, it should be understood that the specific embodiments described herein are only used for understanding the present invention, and are not used for limiting the present invention, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention.

Examples

The utility model discloses a landfill marsh gas collecting well construction is with countersink well stake, including pile cover 1, pile section of thick bamboo 2, pile head 3, pile section of thick bamboo 2 is hollow tubulose, and annular baffle 5 is connected to support one end, center pin 10 is connected to the other end, is equipped with net rack body 6 between annular baffle 5 and center pin 10, is equipped with inlet port 7 on net rack body 6, is equipped with filter screen 9 in net rack body 6, fills quartzy stone interlayer 8 between net rack body 6 and the filter screen 9.

The diameter of the bottom surface of the pile head 3 is slightly larger than the diameter of the section of the pile cylinder 2 and is used for being connected with one end of the pile cylinder 2; the outer diameter of the pile cover 1 is slightly larger than the outer diameter of the pile cylinder 2 and is used for covering the other end of the pile cylinder.

The pile head 3 is a cone, and a spiral sheet 11 is arranged on the cone.

The top of the pile barrel 2 is provided with a lifting ring or a hook which is used for connecting lifting equipment to lift the pile barrel 2 out of a landfill.

When a biogas collection system of a refuse landfill is established, firstly, a certain number of biogas collection wells are drilled on the refuse landfill for landfill of biogas collecting pipes, and the collection wells need to go deep into a refuse layer, so that the depth of the collection wells is generally related to the depth of the refuse layer according to the specific conditions of the refuse landfill; the number of the collecting wells is related to the area of a landfill site, generally, one collecting well is arranged at intervals of 20 meters, vertical sunk cone well piles are embedded in each collecting well, and are connected through a transverse conveying pipe and conveyed to an air storage tank through an air feeder.

The pile barrel collects methane under a garbage landfill site, the quartz stone interlayer is filled between the net rack body and the filter screen, so that the gas outlet is smooth, the porous collecting pipe is effectively prevented from being buried by percolate, the annular clapboard can separate the garbage layer, so that the gas inlet hole on the net rack body is smooth, the methane passes through the hollow pipe at the central shaft of the pile barrel and enters the methane treatment system through the pile cover under the action of the external exhaust fan, and the methane can be effectively enriched.
