卵砾石地层深基坑土钉和锚杆桩联合支护技术
卵砾石地层深基坑土钉和锚杆桩联合支护技术
摘要:卵砾石地层硬度大,可钻性差,易坍塌,这种地层的深基坑支护若采用传统的锚杆桩,施工难度大,工效低,工程造价高。在卵砾石地层中,采用土钉和锚杆桩联合支护技术进行深基坑支护,节省工程投资,提高工效,缩短施工工期。
Abstract:The traditional method of anchor pile on the deep foundation pit bracing in the gravel stratum with high hardness, poor drilling and easy slump is complicated owing to difficult construction, low efficiency and high cost In gravel stratum,the method combined soil nails and anchor pile is adopted in deep foundation pit bracing, it can obviously cut down engineering cost, raise efficiency and shorten construction period.
