Construction method of indoor solid waste landfill for preventing rain and seepage

Patent No.: ZL201310448462.5

Application date: 2013.09.27

Announcement (announcement) date: 2014.01.01

Main technical features:

ü Construction of buildings at the same time as the construction of landfills, including excavation, construction of foundations and anti-seepage treatment above them, construction of building structures, anti-seepage treatment of base soil in landfills and anti-seepage treatment of engineering membranes. Excavation includes earth excavation and partial or complete excavation of earthwork around the landfill; the building structure includes columns, beams and roofs, the column net adopts economic span, the roof adopts organized drainage; the building foundation and columns are made of steel.砼 structure, and anti-corrosion treatment, the combination of building foundation and landfill anti-seepage; construction of pre-treatment station to ensure that solid waste meets landfill standards, so that water content is lower than standard, avoiding leachate

ü The sectional construction method is adopted, that is, a part of the construction is first, and when the landfill is almost filled, the next part is constructed, and the capital investment can be segmented to reduce the capital cost.

ü The landfill is located indoors without rainwater erosion, no leachate production, no leachate treatment cost, environmentally friendly and energy-saving; it can also avoid or significantly reduce the generation of harmful gases in the landfill, and a small amount of exhaust gas that may be generated. It is convenient to collect and process indoors, realize that the landfill has no pollution to the surrounding environment, greatly reduce the site selection of landfills, solve the problem of difficult site selection of solid waste (hazardous waste) landfill and the building can be used as a factory or Use of warehouses to make effective use of land resources
