产品特点

钻进效率高：潜孔锤采用高风压排渣土，可实现排渣彻底、孔底干净、无二次破碎、改善了入岩钻进功效。

成孔质量好：上下动力头采用旋转钻进，减少孔斜的影响，从而提高钻孔的垂直度，同时也可减少孔壁岩石坍陷风险。

输出扭矩大：SHX双回旋潜孔钻机输出扭矩可达527T.m，可有效解决目前国内CFG长螺旋钻机在特殊地质施工时遇到的扭矩不足的情况。

绿色环保：钻进采用干式沉孔作业、噪音低、无泥浆污染。

可进行多功能、多用途施工，特别是能在卵石漂石层及坚硬岩层等复杂地层高效率钻孔，成桩孔径、孔壁形状规整、质量好，垂直精度高，施工无泥浆污染;攻克了大直径桩基础高效率打孔“入岩”的技术难题，解决了桩孔护壁泥浆对环境严重污染的问题，

　　适用地层：各种土层、砂层、卵砾石层、漂孤石层、各种岩层等;

适用桩径孔径：φ500 mm ～ φ1500 mm 。

The advantages of rotary drilling rig

High efficiency: The down-the-hole hammer adopts high air pressure to discharge slag, which can realize slag discharge thoroughly, the bottom of the hole is clean, no secondary crushing, and the effect of rock drilling is improved.

Good effect: The power heads are spirally drilled to reduce the influence of the holes inclination, thereby increasing the verticality of the borehole and also reducing the risk of rock wall collapse of the borehole wall.

Large output torque: The maximum output torque of the SHX double-slewing DTH hammer can reach 52tm, which effectively solve the shortage of torque encountered by the domestic CFG long auger in special geological construction.

Friendly environment: Drilling uses dry countersinking, low noise and no mud pollution.

It can be used for multi-functional and multi-purpose construction, especially for high-efficiency drilling in complex layers such as pebble boulders and hard rock layers. The pile diameter, the shape of the hole wall are regular, the quality is good, the vertical precision is high, and the construction has no mud pollution; The technical problem of high-efficiency drilling of large-diameter pile foundation “rock drilling” solves the problem of serious pollution of the mud by the pile wall retaining wall.

Applicable geology: Various soil layers, sand layer, gravel layer, drifting layer, etc.

Applicable pile diameter: φ500 mm ～ φ1500 mm
