Background
Horizontal directional drilling has been in China for over 20 years, and processes and equipment are well developed. However, with the further development of the infrastructure of our country, more and more pipelines are laid and need to be constructed in the medium and hard rock strata. The common process and equipment are difficult to implement in medium and hard rock strata, and have low construction efficiency and extremely high cost. If the construction process of the ordinary mud motor in the soft rock stratum still consumes a large amount of mud, the mud can be greatly polluted by treatment and dumping, and the construction process is not in line with the current environmental development. The development of horizontal directional drilling process and equipment in medium hard rock formation is urgently needed. The current pneumatic down-the-hole hammer construction method is that the rock breaking drilling efficiency in medium-hard rock stratum is highest, but usually, the pneumatic down-the-hole hammer is not allowed to strongly vibrate due to a plurality of inductors and magnetic signal transmitters in a guide instrument signal transmitting probe during horizontal drilling, and the down-the-hole hammer is high in impact frequency and vibration amplitude during drilling and is easy to damage the probe due to vibration. In view of the above, there is a need for a shock resistant probe magazine for a pneumatic down-the-hole hammer.
