Earthwork backfilling construction spoil cofferdam and rockery construction method
The invention provides a construction method for constructing a spoil cofferdam and a rockery through earthwork backfilling. The construction method comprises the following steps that an excavation area, a spoil site and an excavation flow direction are planned; measuring and verifying the original terrain and landform in the spoil site, and determining the size and the earthwork storage amount of the spoil site; vegetation, miscellaneous fill and sludge in the spoil site are cleaned; filling a spoil cofferdam at the periphery of the spoil site; after the spoil cofferdam is filled, slurry conveying pipelines are orderly placed at the top of the spoil cofferdam, a drain opening is formed in the spoil cofferdam, and an intercepting ditch is formed near the outer edge line of the spoil cofferdam; flushing and digging the flushing and digging area to form slurry, and leading the slurry to a spoil yard through a slurry conveying pipeline to stand, precipitate, drain water and solidify to form the rockery; after the rockery reaches the designed height, a side slope is constructed, and after the side slope is constructed, soil monitoring is conducted on the rockery through observation points. According to the construction method, the problems that the engineering danger coefficient is high, and clay is difficult to excavate mechanically are solved, the transportation process is reduced, and the working efficiency is improved.
本发明提供一种土方回填构筑弃土围堰及假山施工方法，包括以下步骤：规划冲挖区域、弃土场以及冲挖流向；对弃土场内的原始地形、地貌进行测量，核实并确定弃土场尺寸及土方存放量；清理弃土场内的植被、杂填土、淤泥；在弃土场外围填筑弃土围堰；在弃土围堰填筑完成后，将输浆管道有序地安放在弃土围堰顶部，在弃土围堰上施作泄水口，并在弃土围堰外边线附近施作截水沟；对冲挖区域进行冲挖形成泥浆，通过输浆管道将泥浆通往弃土场内进行静置、沉淀、排水和固化以形成假山；在假山达到设计高度后施作边坡，在施作完边坡后，通过观测点对假山进行土体监测。本发明的施工方法解决了工程危险系数高、粘土难以用机械进行挖掘的问题，减少了运输过程，提高了工作效率。
