Arrangement method of longitudinal and transverse drainage and seepage system structure of composite drainage and seepage wall of solid waste landfill
The invention discloses a longitudinal and transverse seepage drainage system structure arrangement method for composite seepage drainage walls of a solid waste landfill, which comprises the following steps: arranging 1-2 seepage drainage wall composite seepage drainage bodies along the longitudinal direction of the solid waste landfill, and arranging 4-6 seepage drainage wall composite seepage drainage bodies along the transverse direction of the solid waste landfill, so as to form longitudinal and transverse seepage drainage systems; the composite seepage drainage body of the seepage drainage wall comprises a coarse sand protection layer (6) and a melon-seed-shaped piece permeable layer (4) from left to right, and vertical non-woven geotechnical cloth (5-1) is externally attached to the two sides of the melon-seed-shaped piece permeable layer (4) respectively; and a broken brick covering layer (7) is laid at the upper part of the composite seepage drainage body of the seepage drainage wall at the heightening stage. The seepage drainage wall composite seepage drainage body is arranged along with the running stage of the landfill, seepage drainage of the landfill is completed by increasing the seepage fracture surface of the percolate and rapidly entering the bottom percolate collecting blind ditch along the seepage drainage wall, construction is convenient, the investment cost is low, pertinence is high, and the seepage drainage requirements of the II-type solid waste landfill with poor water permeability can be well met.
本发明公开了一种固废填埋场复合排渗墙纵横向排渗系统结构布置方法，沿固废填埋场纵向布设1～2道排渗墙复合排渗体，沿固废填埋场横向布设4～6道排渗墙复合排渗体，从而形成纵、横向排渗系统；排渗墙复合排渗体自左向右分别为粗砂保护层(6)、瓜子片透水层(4)、粗砂保护层(6)，在瓜子片透水层(4)两侧分别外贴竖直向无纺土工布(5‑1)；在所述的排渗墙复合排渗体加高阶段上部铺设碎砖块覆盖层(7)。本发明随填埋场运行阶段设置排渗墙复合排渗体，通过增大渗滤液渗流断面，沿排渗墙快速进入底部渗滤液收集盲沟，完成对填埋场的排渗，施工方便、投资成本低、针对性强，能较好的适用于透水性较差的Ⅱ类固废填埋场的排渗要求。
