Problems solved by technology

Therefore, in areas rich in groundwater, spring water often pools and bulges, and the anti-seepage layer bursts, making the anti-seepage function invalid and polluting water quality
In order to restore the remedy, it will consume a huge amount of manpower and material resources

Embodiment Construction

[0021] As shown in Figure 1, the mesh blind ditch guiding system proposed by the present invention includes a mesh blind diversion ditch 1 on the side arm slope, an annular blind diversion ditch 2 at the bottom of the reservoir, a general groundwater drainage pipe 3, a fishbone Shaped diversion blind ditch 4, fan-shaped diversion pipe 5, there is an anchor ditch 6 on the reservoir mouth, and the anchor ditch 6 at each layer of the reservoir mouth is connected with the flood discharge ditch 14 buried in the reservoir dam. Circumferential flood interception and drainage canal 7. A diversion pipe 11 is arranged on the spring eye 10 and is communicated with the general underground water diversion pipe 3 along the diversion blind ditch downward along the slope.

[0022] As shown in Figure 2, all blind ditches are more than 300mm deep and 400-1000mm wide at the mouth, filled with crushed stones 8 with a particle size of 6cm or more, and covered with geotextiles 9 .

[0023] As show...

Abstract

The invention relates to a meshed blind drain leading and draining water method for groundwater in landfill life waste site, and installs a meshed directing blind drain on an entire warehouse bottom and a side slope which is grade separated with the anchoring groove of every layer opening. An upper opening is up to the planning regional of the landfill site, while a lower opening is connected with an annular directing blind drain. A main groundwater drain is longitudinal installed on the lowest part of the warehouse bottom, and a fishbone-shaped directing blind drain is spread between the main groundwater drain and the annular directing blind drain. The outlet end of the main groundwater drain is positioned at the warehouse dam which is equipped with actinoform fan-shaped draining pipes at the forward. The invention drains out the water timely and ordered via the groundwater influence channel with the meshed directing blind drain, and prevents overflowing, forming water collection and ballooning bag, thereby guaranteeing the soil of the warehouse keeping hard, protecting impervious layers, and eliminating water contamination accidents. The invention guarantees the base and the impervious layer of the warehouse in working order, thereby preventing the water contamination and keeping safety and healthy.

Description

technical field [0001] The invention relates to a construction method of a drainage system, in particular to a method for guiding and draining underground water in sanitary landfills of domestic garbage. Background technique [0002] There are strict requirements for the site selection of sanitary landfills for domestic waste, which should meet the conditions of reliable technology, reasonable economy, safety and sanitation, pollution prevention, and gas collection. For the selected landfill, it is required that the site is stable without subsidence, can bear the load after garbage accumulation, and must be treated with anti-seepage. The role of anti-seepage treatment is to prevent groundwater and surface water from entering the landfill area on the one hand, and to prevent leachate from seeping out and polluting water quality on the other hand. [0003] The existing sanitation landfills for domestic waste treatment only passively build an anti-seepage layer, and the key po...
