The RJP-3.0 Method realizes real-time monitoring and regulation of construction parameters through the jet drilling real-time measurement system, addressing the drawback of lacking key parameters in traditional jet grouting technology. It can simultaneously acquire basic parameters such as nozzle holder lifting speed, rotation speed, nozzle diameter and quantity, air pressure, slurry flow rate, and pump outlet pressure. It achieves real-time drilling deviation monitoring and dynamic collection of downhole pressure inside and outside the drill pipe, assists in analyzing the actual kinetic energy of the slurry and inferring the pile diameter, and forms a closed-loop control system by integrating post-construction deviation data. This significantly improves the preparation accuracy of the soil-cement mixture and construction reliability.
主に地盤改良工事やアンカー掘削に使用されるこの製品ラインには、ショベルのサイズにもよりますが、最大15トンの引き上げ力に達することができる、驚くほど多様なモデルがあります。このラインの掘削アタッチメントには、さまざまなロータリーヘッド掘削システムを装備できます。すべてのセットアップと掘削動作は、オペレータが掘削機のキャビンから直接リモートコントロールで制御でき、効率性、生産性、安全性の面で大きな利点があります。
Spherical hobs are very mature and are widely used in many equipment, such as rotary drilling rigs, RCD, pipe jacking machines, etc. By analyzing the use of ball-tooth hobs on the above equipment, it can be known that when there is sufficient propulsion pressure and the rock layer strength is about 130MPa, the footage speed of the spherical tooth hob can be maintained at 0.3~0.5m/ h. And the footage speed is relatively stable. When the spoil discharge is sufficient, the service life of one spherical tooth hob can reach a construction length of 300m.
It is made of high quality steel GB-Q345B with special soil teeth which can avoid inclined hole. This tool is applicable to different layers such as clay, high-weathered layer, gravel, etc. It is a reliable and efficient drill tool for drilling deep hole and wide range of applications.
