Luban Prize Shopping Mall Project construction organization design
Meteorological conditions at the construction site Temperature Extreme maximum temperature and duration 30 ℃ Maximum rainfall in August and rainy season Annual rainfall 607mm, daily maximum rainfall 147mm/June September Extreme minimum temperature and duration - 10 ℃/maximum wind force, wind direction and occurrence time in January are greater than 8/northerly wind in December The freezing depth of winter soil is 0.7m when the average snowfall in winter is less than 10mm Engineering hydrogeological condition Geological structure The upper Quaternary overburden of the site area is mainly miscellaneous fill, silty clay, breccia (silty clay), and the lower bedrock is Sinian Qiaotou Formation slate. The weathering degree starts from the shallow part and gradually goes down to completely weathered slate, strongly weathered slate (strong wind fossil quartzite), and moderately weathered slate (apoplectic quartzite). Nature and type of soil Benchmark and absolute elevation of strongly weathered slate construction area 18.920m The groundwater level elevation and the groundwater flowing to the site are phreatic water, which is recharged by atmospheric precipitation and seawater. The stable phreatic water level is about 0.30~6.10m below the ground, equivalent to 18.04~18.18m of the Yellow Sea elevation.
