Description

Construction method of waste dumping and its device for preventing environmental pollution

The present invention forms a drainage hole at the bottom of the waste dumping area at the periphery of the waste dumping area where the waste is accumulated, and then installs a PVC water curtain and a drain pump by using a separate support frame in the drainage hole to form a waste dumping area. By blocking it from the outside, it is possible to easily remove the effluent generated by the decay of the garbage, and install a filtration corrugated pipe for collecting and discharging the gas in the upper part of the garbage dump and then the outside of the PVC The PVC barrier membrane, which is fused with the upper part, is installed to be sealed with the outside, so that the odorous gas generated when the garbage is buried is burned as a gas burner through the gas discharge pipe to prevent the environment and pollution pollution around the dump site. Garbage inside the dump site is centralized by impact compression. Standing construction method of garbage Arena for the prevention of environmental pollution, so can increase the promotion of soil strength and avoid differential settlement and bearing capacity and to the device.

In general, the waste accumulated in the dumping ground is only landfilled, so the waste water caused by the decay of the trash is permeated into the surrounding ground, which causes environmental pollution, and the odors such as gas are emitted to the outside. It has been a source of pollution, and because of the uneven compression of accumulated waste, there is a defect that the bearing capacity and the strength of the ground decrease.

Therefore, the present invention forms a drainage hole in the circumference of the garbage dump and fills the sand gravel with the PVC water repellent membrane and the drainage pump installed therein, thereby forming a sand circumference wall in which the wastewater sedimentation chamber is formed to be blocked from the outside. Form a garbage dump.

Thus, the waste accumulated in the interior of the sand circumference blocked by the outside forms a plurality of central compaction holes by the impact compression compact to fill the sand gravel to form a gas collecting cylinder, and the upper part of the gas collecting cylinder In the gas collection chamber, a filtration corrugation pipe serving as a gas collection discharge passage is installed, and a clay layer is laid on the upper part to cover the PVC barrier film, and the waste accumulated in the sand circumference wall is sealed by the water barrier film and the barrier film. By installing it as much as possible, it is easy to remove the odors of waste water and gas tanks caused by garbage decay, and to prevent the pollution of the environment and pollution. Also, by compacting the impact impact, it is possible to promote settlement of ground, increase strength and prevent inequality. It is proposed to increase the bearing capacity.

After installing the pump (9), which is drawn out, and filling the sand gravel (10), the drain hole (2) forms a sand circumferential wall (11) that blocks the outside of the dump site while the pump (9) The lower portion to be installed is to form the chip chamber 11a of the waste water.

In this way, the applicant's first invention is selected by using an ordinary crane (not shown) or the like on the top of the rubbish 1 accumulated in the sand circumference 11 installed at the circumference of the dump site. A number of pivotal compaction holes 12 are formed while performing the impact compression compaction by dynamic compaction, which is proposed in No. 96-3748. Filling the sand gravel 10 in each of the central compaction hole 12 so that the respective gas collecting container 13 is formed, so that the upper portion of each gas collecting container 13 formed as described above becomes a gas collecting chamber 14, In the gas collecting chamber 14, the filtration corrugated pipe of the structure proposed in the selection of the applicant (Patent Publication No. 96-3745) was buried so as to be the gas collecting discharge passage 15. The collection discharge passage 15 is connected to the gas burner 17 by the gas discharge pipe 16.

The structure of the filtration corrugated pipe to be the respective gas collection discharge passage 15 has a concave inlet ring 19 and the protruding wheel 20 through which the gas collecting holes 18 are drilled as shown in Patent Publication No. 96-3745. It is a structure formed by surrounding the filter cloth 22 around the formed corrugated tubular body 21 and easily collects and discharges gas such as odors emitted as the garbage 1 decays.

The upper part of the gas collection chamber 14 in which the filtration corrugated pipes which become the respective gas collection discharge passages 15 were embedded from the upper part of the sand circumferential wall 11 serving as the upper part of the waste dumping site installed in such a configuration is the soil layer 23. ) Is installed so as to be laid, and then the outer surface of the laminar layer 23 is covered with a PVC blocking film 24 so that the peripheral end of the blocking film 24 is attached to the outer frame 4a forming the support frame 3. The waste 1 accumulated in the waste dumping site is installed to be sealed to the outside by being fusion-fixed and installed as a fusion unit 24a at the upper end of the PVC water shield 7, and the outside of the PVC barrier 24 is covered with soil 25.
