葫芦素选煤厂位于鄂尔多斯乌审旗图克镇,该区域地处毛乌素沙漠腹地,厂区自然地坪绝对高程为1305.30m,地下水丰富,地下水静止水位埋深约1.2m,土质条件复杂,土层分布不均匀,各层土的渗透性不同,降水难度大。葫芦素选煤厂4号转载点基础底标高-14.5m,工程根据地质情况及周边环境采用了深井与轻型井点相结合的降水方案,放坡与钢管桩喷锚支护相结合的支护方案,安全快速的完成深基坑施工,节约了施工成本,该施工方法和思路在地下水丰富、周边环境复杂的砂土地区深基坑施工具有很好的借鉴意义。
The cucurbite coal preparation plant is located in Tuoke Town, Wushenqi, Ordos. This area is located in the hinterland of the Maowusu Desert. The natural elevation of the natural floor of the plant is 1,305.30m, and the groundwater is abundant. The groundwater still water depth is about 1.2m, and the soil conditions are complex. The distribution is not uniform, the permeability of each layer of soil is different, and precipitation is difficult. The base elevation of the 4th transfer point of the Hulusu Coal Preparation Plant is -14.5m. The project adopts a combination of deep wells and light wells based on geological conditions and surrounding environment. The combination of grading and steel pipe piles with anchored bolts The protection plan can safely and quickly complete the construction of the deep foundation pit and save the construction cost. The construction method and ideas have a good reference for the construction of deep foundation pits in sandy soil areas where the groundwater is abundant and the surrounding environment is complex.
