1.采用电脑系统控制定位,保证成孔的各项指标:旋挖钻机操作由全液压系统控制(全电脑控制),桩孔对位方便准确,在对位过程中操作手在驾驶室内利用先进的电子设备就可以精确地实现对位,使钻机达到最佳钻进状态,有效保证成孔的各项指标。

2.适用不同地质情况,成孔效率高:旋挖钻机是常规桥梁桩基回旋钻机成孔的5~6倍,是冲击钻成孔的28~35倍。且旋挖钻机的履带机构可将钻机方便地移动到所要到达的位置,而不像传统循环钻机移位那么繁琐,有效地促进施工进度。

3.施工噪音低,不污染环境:与传统的循环钻机相比,旋挖钻机可以取土外运保证施工现场平整,而传统循环钻机是不断地产生泥浆,而且旋挖钻机也可适用于无泥浆(称干钻)成孔作业。

4.质量可靠:孔壁稳定性好,成孔后清孔彻底,施工进度快,施工质量有保证。

1.using the computer control system of positioning, ensure the index hole: the operation is controlled by hydraulic system of rotary drilling rig (full computer control), convenient and accurate in the process of pile hole alignment, para operation in the cab by using advanced electronic equipment can accurately position, to achieve the best state of drilling rig. To effectively guarantee the whole index.

2.For different geological conditions, the efficiency of the whole formation is high: the rotary drilling rig is 5~6 times the whole of the conventional bridge pile, and it is 28~35 time the whole of the percussion drill. Moreover, the crawler mechanism of rotary drilling rig can easily present the drilling rig to the desired location, instead of the traditional circular drilling rig, which is cumbersome and effective in promoting construction progress.

3.construction noise is small, and the environment is not polluted. Compared with the traditional circulating drilling rig, the rotary drilling rig can carry out the earth's outward transportation to ensure the leveling of the construction site, while the traditional circulating drilling machine produces mud continuously, and the rotary drilling rig can also be applied to the drilling without mud (dry drilling).

4.Reliable quality: the stability of the entire wall, hole Houqing completely, fast construction progress, has to ensure the quality of construction.
