Driven by the dual drive of “double carbon” goal and diversified infrastructure demand, the working device of rotary drilling rig is undergoing a leapfrog upgrade from a single function to a multi-dimensional empowerment. As the core carrier of pile foundation engineering, its technical iteration is not only related to the construction efficiency, but also has become the key fulcrum of the green transformation of the industry. Based on the market demand and technological breakthrough, the rotary drilling rig working device will focus on four major development directions in the future:
(1) Direction 1: large-scale breakthrough engineering limits
Focusing on the needs of super engineering such as cross-sea Bridges and super high-rise buildings, rotary drilling GS are accelerating in the field of “large torque + ultra-deep hole”. The new generation of super-large equipment can output more than 1000 k N·m torque, the hole depth exceeds 150 meters, is suitable for the super-large aperture construction of more than 3.5 meters, and integrates the multi-engineering intelligent switching system to realize the composite functions such as hard rock crushing and rotary jet grouting, overcome the construction problems of complex strata, and improve the comprehensive efficiency by more than 40%.
(2) Direction 2: miniaturization to activate the sinking market
In the face of the new rural transformation, municipal pipe network and other refined scenarios, the lightweight rotary drilling rig with a “small figure + big energy to reconstruct the market pattern”. The weight of the whole machine is controlled within 30 tons, supporting the flexible transfer of small site, with electric power scheme, energy consumption is reduced by 25%, noise pollution is reduced by 60%, fully replace the traditional positive and reverse cycldrilling machine, and open up the “blue ocean track” for small pile foundation construction.
(3) Direction 3: integration to achieve a green closed-loop
Under the promotion of “waste-free site” policy, the working device of rotary drilling rig is transformed from single drilling to full chain environmental protection. Innovate integrated mud zero discharge system, realize instant mud regeneration through solid-liquid separation and water circulation module; synchronously carry intelligent muck compaction device, compress the drilling slag and automatically load the car, reduce the cost of waste transportation by 90%, and create a green process of “drilling-treatment-recovery”.
(4) Direction 4: intelligent reshaping operation paradigm
Relying on 5G + edge computing technology, the new generation of working devices will build a closed-loop system of “perception-decision-execution”. Equipped with high-precision geological prediction sensor, which can analyze the hardness of rock layer in real time and automatically match the drilling parameters; the quick change interface can switch 12 tools such as screw drill, barrel drill and bottom extender within 3 minutes. Combined with the remote control platform, the “unmanned” accurate construction is realized, and the comprehensive failure rate is reduced by 70%.
Industry outlook: Technology convergence promotes new quality productivity
From “mechanical tools” to “intelligent terminal”, the upgrade path of the rotary drilling rig working device clearly reflects the evolution logic of the construction machinery industry. —— Solve the construction pain points with scene customization, and enhance the value density with technology integration. With the deep penetration of new materials, new energy and artificial intelligence, the rotary drilling RIGS will continue to expand the application boundary and provide higher-dimensional solutions for emerging fields such as smart city and new energy infrastructur.
