CJ-130型双向气动潜孔锤施工工艺初步研究

Preliminary Study on Construction Crafts of CJ-130 Two-way Pneumatic DTH

摘要:

CJ-130型双向气动潜孔锤是锚固工程施工领域的一种新机型，其应用于施工时，由于无操作规程可循，在一定程度上影响了其设计性能的发挥。在介绍潜孔锤成孔施工的主要设备和施工流程的基础上，对其钻进规程和参数进行了初步的分析探讨，并对施工中所涉及的技术要点和注意事项进行了归纳总结，以期为以后的岩土工程锚固施工提供部分技术指导，并为后续研究者提供一些具有参考借鉴意义的资料。

Abstract:

CJ-130 two-way pneumatic DTH is a new type drilling machine, which has been successfully applied to the construction in the field of anchor engineering. However, its design functions were affected in a certain degree by lacking of the operation rules and regulations. On the basis of introduction of the construction equipments and processes of CJ-130, the drilling rules and parameters were analyzed and the key operational points and notes were summarized in order to provide a technical guidance in the future geotechnical anchor engineering construction and provide some valuable references for later researchers.
