Precipitation method for fan foundation of 200MW wind power project
The invention relates to the technical field of wind power project construction, in particular to a 200MW wind power project fan foundation precipitation method which comprises a deep well point precipitation method and further comprises the step of conducting light pipe network precipitation on a foundation pit where deep well point precipitation cannot achieve a precipitation task, and the light pipe network precipitation comprises the following steps that S001, paying-off positioning is conducted; step S002, drilling a well hole; s003, a well casing is buried; s004, a header pipe is installed; s005, the well pipe communicates with the main pipe; according to the construction method, deep well dewatering construction needs to be adopted for foundation pits on the construction site of the fan foundation of the 200MW wind power project, light well points are added in a targeted mode, deep well and light ring network pipe combined dewatering construction is conducted, and the geological characteristic difficulty that the water level is too high is overcome through the technology that deep well dewatering is combined with light pipe network dewatering; and the construction quality and progress are guaranteed, engineering construction is better promoted, and better reference is provided for solving draught fan foundation precipitation construction work of a wind power project in the actual engineering operation process.
本发明涉及风电项目施工技术领域，具体公开了一种200MW风电项目风机基础降水方法，包括深井井点降水方法还包括对深井井点降水无法达到降水任务的基坑进行轻型管网降水，所述轻型管网降水包括如下步骤：步骤S001：放线定位；步骤S002：打井孔；步骤S003：埋设井管；步骤S004：安装总管；步骤S005：将井管与总管接通；步骤S006：安装抽水，在本发明中，200MW风电项目风机基础施工现场基坑均需采用深井降水施工，有针对性的增加轻型井点，深井与轻型环网管联合降水施工，通过深井降水结合轻型管网降水技术，克服了水位过高的地质特性困难，保证了施工质量和进度，更好地促进工程的施工，也为工程实际操作过程中解决风电项目风机基础降水施工工作提供更好的参考。
