旋挖钻机成孔优点

Advantages of hole forming in rotary drilling rig

1.选用电脑系统操控定位，确保成孔的各项目标：旋挖钻机操作由全液压系统操控（全电脑操控），桩孔对位便利准确，在对位过程中操作手在驾驭室内使用先进的电子设备就能够精确地完成对位，使钻机抵达最佳钻进状况，有用确保成孔的各项目标。

1. use the computer system control and positioning to ensure the objectives of the hole. The rotary drill is operated by the full hydraulic system (full computer control), the pile hole is convenient and accurate. In the counterposition, the manipulator can accurately complete the position by using the advanced electronic equipment in the control room, so that the drill can reach the best drilling condition. Use the targets to ensure the hole.

2.适用不同地质状况，成孔效率高：旋挖钻机是惯例桥梁桩基回旋钻机成孔的5～6倍，是冲击钻成孔的28～35倍。且旋挖钻机的履带组织可将钻机便利地移动到所要抵达的方位，而不像传统循环钻机移位那么繁琐，有用地促进施工进度。

2. for different geological conditions, the efficiency of drilling is high: the rotary drilling rig is 5~6 times the conventional bridge pile foundation rotary drilling machine, and 28~35 times the impact drilling hole. And the crawler organization of the rotary drilling rig can move the drill conveniently to the direction to reach, rather than the traditional circular drilling rig, which is so complicated and useful to promote the construction progress.

3.施工噪音低，不污染环境：与传统的循环钻机相比，旋挖钻机能够取土外运确保施工现场平整，而传统循环钻机是不断地发生泥浆，并且旋挖钻机也可适用于无泥浆（称干钻）成孔作业。

3. the construction noise is low and the environment does not pollute the environment. Compared with the traditional circular drilling rig, the rotary drilling rig can take the soil to ensure the smooth construction site, while the traditional circulating drilling rig is constantly occurring in mud, and the rotary drilling rig can also be applied to the drilling operation without mud (called dry drill).

4.质量牢靠：孔壁稳定性好，成孔后清孔完全，施工进度快，施工质量有确保。

4. the quality is reliable: the stability of the hole wall is good, the hole after completion is complete, the construction progress is fast, and the construction quality is ensured.
