Sanitary filler dwg
Design of proofing bottom and cover in sanitary filler. a filler gives security ;must guarantee the tightness through barriers designed to avoid the negative goods on the environment .this method was applied in those residuals that have been treated until its maximun possibilities;that can not be actionable ; recyclables; fuel,or can be mitigated their risk characteristics.technical characteristics for the construction of a secure landfill: 1) also in this type of fillings can not be use fillers with the following ones characteristics;: a) that they possess free liquids. b)generating spill at room temperature. c) that they possess substances which may contain barriers under the landfilll. d) that they possess transportable pollutants in the air. e)high solubility in the water ;in concentration of agreement to the type and danger gives the substance . f) substances that generate combustion in the local situation g)dangerous like the group of tetra; penta;hexacloro , ibenzoparadioxinas; dibenzofuranos; tri; tetra y penta clorofenoles;and derivatives clorofenoxidos halogenated compound and derivatives. 2) no rots to prepare in the same cell residuals that can produce adverse reactions like : a) heat , pressure , explosion or react violently . b) any kind of toxic or flammable fumes . c)damage to the srtucture of filling .in the case that the filler no fullfills the mentioned characteristics the treatment will be made for the adaptation to the same ones . 1) do not install fillers in flood areas or of use potable water .exceptionally must be authorized by the authority of application; being the pollution limits of transportation the limits for the drinking water.in cases in which was naturally contaminated and can not be used as a drinking water; the authority of application will define the limits of contamination in the table as the product among a factor of mayoracion and the limits of drinking water . 2) the minimal distance between the filling of safety to the first phreatic water table should be of 3m metros. 3)the minimun distance to the urban centers will be 5km kmfor smaller values must apply for approval to tha authority of application with the technical justification. 4)perimeter strip may not be below taken to the edge 50m to the property ; should build attending the landscape and as physical barrierto prevent the action of wind increase risks,spill of waste . 5)the land will be closed to the limit of the property with controlled access . 6)waste transportation to avoid traffic for urban areas . 7) waterproofing of bases and slopes;minimun requirements :double layer waterproofing system i(primary and secondary) composed. . 8)drainage layer to driver unwanted flows and that ensures the absence of a load on hydraulic waterproofing system. 9)drainage ducts should be hdpe or equivalent materialwith a diameter minimun of 20cm and sufficient thickness to prevent warping pressure ;and placed on such a form that it allows the drain only under gravity and the possiilityof being controlled stop after the close 20 years secure landfill. 10) waterproof cover must comply with them recommendations regarding minimum thickness ,permeability and features physical - chemical barrier to fundcover design to ensure : the free glide avoiding the depressions of accumulation water preventing the waste outlet outside the tank. including the period of closure.be installed on a base to support the coating and resitance to pressure gradients that may act allow and bellow the coating to prevent the colaps of this for the compression 11)on the cover waterproof must be a layer of vegetable floor permitted by evaporation and prevent erosion . 12)must be ensured that the gases formed found a road of controled exit and monitor to avoid internal over pressure . 13)between the base and landfill secure ground water must design a water table of monitoring system to detect pollution by transport by leachape before coming to the napa.
