Flexible drainage ditch construction method
The invention provides a flexible drainage ditch construction method. The flexible drainage ditch construction method comprises the steps that S1, the trend and size of a drainage ditch are designed according to distribution of gas collecting vertical shafts in a landfill; s2, a trench foundation pit of the drainage ditch is excavated through an excavator, and the excavated trench foundation pit is filled with broken stones; s3, the foundation pit is excavated through a shaping excavator bucket, and the gravel is shaped into a groove shape; s4, geocells are machined according to the shape of the cross section of the groove, and the geocells are laid in the groove; s5, the geocell is filled with plain concrete, and the plain concrete is flattened; and S6, geotextile is laid on the upper surface of the plain concrete before the plain concrete is solidified, the plain concrete is poured again, and then the plain concrete is cured. The foundation pit is filled with broken stones, the broken stones cope with the settlement stress of the landfill site, the drainage ditch is prevented from being damaged, meanwhile, the drainage ditch can bear certain deformation tensile stress through the earthwork standard room, the overall stability of the drainage ditch structure is kept through deformation when settlement occurs, and the anti-seepage performance of the wasteyard can be further improved.
本发明提供一种柔性排水沟施工方法，包括：步骤S1，根据填埋场内的集气竖井分布设计排水沟走向以及尺寸；步骤S2，通过挖掘机进行排水沟的沟槽基坑开挖，在开挖的沟槽基坑内填充碎石；步骤S3，利用定型挖斗在基坑进行开挖，使碎石定型为沟槽形状；步骤S4，根据沟槽截面形状加工土工格室，将土工格室铺设在沟槽内；步骤S5，在土工格室内填充素砼并抹平；步骤S6，在素砼凝固之前在素砼上表面铺设土工布，并再次浇入素砼后进行素砼养护。基坑内填充碎石，通过碎石应对填埋场沉降应力，避免排水沟损坏，同时排水沟通过土工格室，能够承受一定的变形拉伸应力，在发生沉降时通过变形保持排水沟结构整体稳定性，能够进一步的提高垃圾场的防渗流性能。
