Construction method of water-rich red sandstone geological underground water level control
The invention discloses a construction method of water-rich red sandstone geological underground water level control. According to the construction method of water-rich red sandstone geological underground water level control, layered excavation is adopted, a set of independent light well point dewatering equipment is arranged on the layer before each layer is excavated, and before the next layeris excavated, the water level of the water-rich red sandstone soil layer is lowered to below 1 meter of the excavated layer through the light well point dewatering equipment on the layer; and the steps are repeated till a foundation pit is excavated to 0.5 m above the designed elevation of a pit bottom, manual excavation is adopted, and the foundation pit is excavated manually to the designed elevation and leveled. According to the construction method, the underground water level of the red sandstone-rich construction area can be effectively controlled, the red sandstone is prevented from being disturbed by the disturbance intensity when encountering water, and meanwhile the construction efficiency is improved.
本发明公布了一种富水红砂岩地质地下水位控制的施工方法，采取分层开挖，每层开挖前本层设置一套独立的轻型井点降水设备，下一层开挖之前，通过本层轻型井点降水设备将本层富水红砂岩土层的水位降到被开挖层的1米之下，如此往复，直至基坑开挖至坑底设计标高以上0.5米时转用人工开挖，人工开挖至设计标高并整平。本发明的施工方法可有效控制富红砂岩施工地区的地下水位，防止红砂岩遇水受到扰动强度下降，同时提高施工效率。
