旋挖鉆機(jī)成孔優(yōu)點(diǎn)

Advantages of hole forming in rotary drilling rig

1.選用電腦系統(tǒng)操控定位，確保成孔的各項(xiàng)目標(biāo)：旋挖鉆機(jī)操作由全液壓系統(tǒng)操控（全電腦操控），樁孔對(duì)位便利準(zhǔn)確，在對(duì)位過程中操作手在駕馭室內(nèi)使用先進(jìn)的電子設(shè)備就能夠精確地完成對(duì)位，使鉆機(jī)抵達(dá)最佳鉆進(jìn)狀況，有用確保成孔的各項(xiàng)目標(biāo)。

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(zhì)狀況，成孔效率高：旋挖鉆機(jī)是慣例橋梁樁基回旋鉆機(jī)成孔的5～6倍，是沖擊鉆成孔的28～35倍。且旋挖鉆機(jī)的履帶組織可將鉆機(jī)便利地移動(dòng)到所要抵達(dá)的方位，而不像傳統(tǒng)循環(huán)鉆機(jī)移位那么繁瑣，有用地促進(jìn)施工進(jìn)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(huán)境：與傳統(tǒng)的循環(huán)鉆機(jī)相比，旋挖鉆機(jī)能夠取土外運(yùn)確保施工現(xiàn)場(chǎng)平整，而傳統(tǒng)循環(huán)鉆機(jī)是不斷地發(fā)生泥漿，并且旋挖鉆機(jī)也可適用于無泥漿（稱干鉆）成孔作業(yè)。

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(zhì)量牢靠：孔壁穩(wěn)定性好，成孔后清孔完全，施工進(jìn)度快，施工質(zhì)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.
