人工挖孔桩群桩施工效率的提升

Construction Efficiency Improvement of Group Artificially Excavated Piles

人工挖孔桩具有承载力大、适应性强、造价低等优点,在当代桩基工程施工中依然发挥着重要的作用。人工挖孔桩采取手工或半机械化施工,在数量较多的群桩施工中施工组织难度大。如组织不当,施工工效将大大降低,严重影响工程施工进度。采取临时电路架空、集中排水、机械化水平运输、定性钢模、排孔凿岩等方法,将大大提升群桩施工效率,加快施工进度。

Artificial digging pile has the advantages of large bearing capacity,strong adaptability and low cost. It plays an important role in the contemporary pile foundation construction. Artificial digging pile to take manual or semi-mechanized.Construction organization is difficult with group artificially excavated piles. If improper organization,construction efficiency are greatly reduced,the progress of construction will be seriously affected. Adopting overhead temporary electricity lines,concentrated drainage,horizontal transport mechanization,qualitative steel mold,row hole drilling and other methods,will greatly enhance the efficiency of pile group construction and speed up the construction schedule.
