Embodiment 1

[0024] Such as figure 1 with figure 2 As shown, the road structure for driving on the garbage dump of the landfill in this embodiment includes a layer of rolled stones 2, a layer of graded pebbles 3, an anti-seepage layer of HDPE film 4, and cement Stabilized gravel base 6, emulsified asphalt lower seal 7, medium-grained asphalt concrete surface 8, emulsified asphalt sticky layer 9 and fine-grained asphalt concrete surface 10, emulsified asphalt lower seal 7 is used to bond the cement-stabilized gravel base 6 and the medium-grained asphalt concrete surface course 8, and the emulsified asphalt adhesive layer 9 is used for bonding the medium-grained asphalt concrete surface course 8 and the fine-grained asphalt concrete surface course 10.

[0025] The rolled stone layer 2 is laid on the garbage dump body 1, and then the graded pebble layer 3 is laid on the rolled stone layer 2, which is used to reinforce the bearing capacity of the garbage layer, slow down the uneven settlemen...

Embodiment 2

[0032] The road structure of driving on the rubbish dump body of the landfill of the present embodiment is basically the same as that of the embodiment, the difference only being:

[0033] In this embodiment, an upper composite geotechnical drainage net and a lower composite geotechnical drainage net are respectively provided on the upper and lower sides of the anti-seepage layer 4 of the HDPE film. The upper and lower layers of composite geotechnical drainage net and HDPE membrane anti-seepage layer 4 form an interlayer, which has the function of guiding water and air, and can guide water and air in the same horizontal plane into other drainage and exhaust systems.

Abstract

The invention discloses a road structure for driving on a refuse heap body of a refuse landfill. The road structure comprises a rolling block stone layer, a graded pebble layer, an HDPE film impermeable layer, a cement stabilized gravel base layer, an emulsified asphalt lower sealing layer, a medium-grain asphalt concrete surface layer, an emulsified asphalt adhesive layer and a fine-grain asphaltconcrete surface layer which are sequentially arranged from bottom to top. The rolling block stone layer is paved on the refuse heap body; the emulsified asphalt lower sealing layer is used for bonding the cement stabilized gravel base layer and the medium-grain asphalt concrete surface layer; and the emulsified asphalt adhesive layer is used for bonding the medium-grain asphalt concrete surfacelayer and the fine-grain asphalt concrete surface layer. The flexible structure is adopted wholly, so that the structure damage to the road caused by the uneven settlement of the garbage can be adapted, the integral bearing capacity is improved, the horizontal impermeable function is added, the water guide efficiency is enhanced, the problem of low service life is solved, and the environmental pollution risk control capability is improved.

Description

technical field [0001] The invention relates to the technical field of garbage disposal, in particular to a road structure for driving on a garbage dump in a garbage landfill. Background technique [0002] With the increasing amount of urban garbage, the difficulty of garbage disposal is also increasing. The existing waste disposal generally adopts landfill. Garbage landfills generally plan supporting auxiliary roads, but the existing technology is to directly pave a 1-meter-thick earth-stone rolling roadbed (80% stone and 20% soil mixing) on ​​the garbage dump body, and lay a layer of roadbed on the roadbed surface. Gravel road. Its structure has a short service life and frequent maintenance, and because the road is built on the garbage dump, the road is prone to cracks, flooding, mud and other diseases due to the uneven settlement of garbage, and there is an environmental risk of sewage overflow in severe cases. Based on environmental protection standards, the requireme...
