旋挖鉆機成孔優點

Advantages of hole forming in rotary drilling rig

1.選用電腦系統操控定位，確保成孔的各項目標：旋挖鉆機操作由全液壓系統操控（全電腦操控），樁孔對位便利準確，在對位過程中操作手在駕馭室內使用先進的電子設備就能夠精確地完成對位，使鉆機抵達最佳鉆進狀況，有用確保成孔的各項目標。

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.適用不同地質狀況，成孔效率高：旋挖鉆機是慣例橋梁樁基回旋鉆機成孔的5～6倍，是沖擊鉆成孔的28～35倍。且旋挖鉆機的履帶組織可將鉆機便利地移動到所要抵達的方位，而不像傳統循環鉆機移位那么繁瑣，有用地促進施工進度。

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，不污染環境：與傳統的循環鉆機相比，旋挖鉆機能夠取土外運確保施工現場平整，而傳統循環鉆機是不斷地發生泥漿，并且旋挖鉆機也可適用于無泥漿（稱干鉆）成孔作業。

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.質量牢靠：孔壁穩定性好，成孔后清孔完全，施工進度快，施工質量有確保。

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.
