硬岩非开挖钻进摆动式潜孔锤驱动马达的研究

Study of non-dig oscillate-drilling DTH drive motor applied on hard rock stratum

在硬岩中进行非开挖铺管是一国际性难题,其主要难点是如何在钻进过程中改变钻头行进轨迹。在分析目前非开挖硬岩钻进导向技术的基础上,针对非开挖硬岩地层气动潜孔锤钻进方式,首次提出并设计了摆动式潜孔锤驱动马达机构,分析并给出了该机构的设计理论依据,叙述了其工作原理,设计并制作了样机,通过试验证明方案可行,为解决非开挖硬岩钻进导向技术难题和关键技术提供了一种新的途径和方式。

It is an international problem that Trenchless Pipe laying Carried out on hard rock stratum by non-dig technology.It is the key part how to Change the bit of motion trajectory In the drilling process.Based on the analysis of Non-Dig hard rock drilling-oriented technology Currently,A Non-Dig Oscillate-Drilling DTH Drive motor device design is brought forward which can apply in hard rock stratum For DTH drilling method.Hard Rock Drilling for Non-Dig DTH drilling method,The first is proposed and designed a swing DTH drive motor agency.The theoretical basis of the institution is analyzed.Working Mechanism is described.A prototype is designed and produced.Test on the prototype proved feasible.A new manner is provided to solve the non-oriented technical problems and the key technology on the hard rock drilling.
