Construction method for building inspection well in quicksand layer and sludge layer
The invention discloses a construction method for building an inspection well on a quicksand layer and a sludge layer, which comprises the following steps: step 1, drilling a pit on the ground, adding high-concentration slurry by adopting an impact drilling machine, and drilling the pit on the ground; a working pit larger than the diameter of the inspection well is dug; step 2, manufacturing an inspection well: manufacturing the inspection well on site according to design requirements and the size fit of the working pit; and 3, water is injected into the inspection well, and the prefabricated inspection well is filled with water. The effect of efficiently utilizing waste heat of the dilute nitric acid production system is achieved, the requirement for digging a precipitation well is omitted, cost is reduced, construction time is short, meanwhile, large-area damage to a construction site is avoided, influences on life of people are reduced to the maximum extent, and pollution to the environment is prevented.
本发明公开了一种在流沙层和淤泥层建造检查井的施工方法，该在流沙层和淤泥层建造检查井的施工方法包括以下步骤：该在流沙层和淤泥层建造检查井的施工方法包括以下步骤：步骤一：地面钻坑，采用冲击式钻机，加入高浓度的泥浆，打出一个大于检查井直径的工作坑；步骤二：检查井制作，根据设计要求，以及工作坑的尺寸配合，在现场制作检查井；步骤三：检查井注水，预制好的检查井内注满水。本发明实现稀硝酸生产系统余热高效利用的效果，省去了打降水井的需求，不仅降低了成本，并且施工时间短，同时不会对施工现场造成大面积破坏，最大程度降低影响人民的生活，也防止了对环境的污染。
