摘要
邯钢新区污水处理站和换热站工程中的地下水池为深基坑施工,基坑深分别为13.7,13.5 m。上部为黏土层,下部为砂卵层,地下水位丰富。根据工程实际选择上土钉墙下护壁桩组合支护技术,该技术充分利用上部较浅部位的土钉墙支护作用和下部较深部位护壁桩支护作用,在工程中成功应用,安全可靠,经济实用。在深基坑支护中值得推广使用。
The undergrand pool is deep foundation pit in the sewage treatment station and heat exchange station in new developed area of Handan Steel Iron Co.Ltd,the excavation is 13.7 m and 13.5 m deep respectivly.the excavation has rich groundwater and with claypan at upper part and sand gravel stratum at lower part.According to the real engineering situation,the combined supporting technology is adoped with soil nailing wall at upper part and retaining piles at lower part,the technology makes full use of the soil nailing wall support at upper shallow position and retaining piles at lower deep position,the technology is safe,reliable,economical and practical.It is worth popularizing in deep excavations.
