振动锤沉拔钢护筒与旋挖钻机钻进的组合应用

Combined Application of Steel Casing by Vibrating Hammer and Rotary Drilling Rig

摘要:

振动锤沉拔钢护筒与旋挖钻机钻进工艺相结合，充分发挥了振动锤适用于软土地区各种施工环境和各类桩型，包括陆地、水上、水下的打桩、拔桩、沉箱作业，地下防渗墙、土壤压实优越性，也发挥了旋挖钻机施工速度快的优越性，同时也拓宽了旋挖钻机对软土地区施工的领域，提高了旋挖钻机施工软土地区桩基的效率和质量，为旋挖钻机施工类似地层提供了技术参考和借鉴的经验。

Abstract:

Advantages of vibrating hammer were brought into play while sinking steel supporting tube by vibrating hammer combining with rotary drilling rig in different construction environments and pile types, such as piling on land, in and under water, pile pulling, caisson, underground seepage wall and soil compaction in soft ground. And high velocity of rotary drilling rig was also fully played. It provided the reference for rotary drilling rig construction in similar ground.

Key words:vibrating hammer; steel casing; rotary drilling rig; pile foundation construction
