- Construction For foundations, pilings, and site preparation, DTH techniques enable precise hole placement and stability in challenging geological conditions.

1.Downhole drilling machine: When drilling a downhole gun hole with a aperture less than 150 mm, in addition to the application of a rock drill, it can also be used to drill a small diameter of 80 ~ 150 mm. When drilling a gun hole with a diameter of less than 70 mm in coal or softer mineral rock, it is generally used to drill or air drill, driven by a motor (or air motor) to drill the drill pipe, and the rock (coal) chips drilled out are discharged through the spiral groove on the drill pipe.

In conclusion, spiral foraging offers a unique and sustainable approach to gathering wild edibles. By combining ecological understanding with a systematic method of exploration, foragers can cultivate a deeper appreciation for nature while minimizing their impact on the environment. This technique not only enhances the foraging experience but also promotes responsible practices that benefit both the gatherers and the ecosystems they inhabit. As we continue to seek sustainable food sources, methods like spiral foraging serve as valuable reminders of our interconnected relationship with the natural world.

Drilling rig is a tool used to directly mine stone. It drills through rock layers to extract stone or other stone works.

At its core, submarine hammer drilling employs a powerful hammer mechanism to drive a drill bit into the seabed. The system utilizes both air and water pressure to deliver repeated impacts on the drill bit, which enables it to break through hard rock formations or sediments that might hinder installation efforts for marine infrastructure. The design of the hammer ensures that the energy is efficiently transmitted to the drill bit, allowing it to operate at significant depths.

2. Construction and Civil Engineering Heavy slurry pumps are equally important in construction, particularly in the dredging process where materials like sand, silt, and clay are extracted from water bodies. They help in maintaining the flow of materials and can be used in dewatering applications during excavation processes, significantly accelerating project timelines.

Self-priming slurry pump solutions are cutting-edge pumping systems designed to handle abrasive and viscous materials with ease. These pumps are equipped with unique priming capabilities that eliminate the need for external priming sources, making them ideal for applications where traditional pumps fall short.

Second, the use and characteristics of the drilling rig:
1). Use:
Engineering anchoring drill can be used in urban construction, railway, highway, river, hydropower and other projects to drill rock anchor hole, anchor hole, blasting hole, grouting hole and other drilling construction.
2). Features:
1, the drill selects the motor through the high-performance reducer as the reverse power; Use cylinders for propulsion. The hydraulic system is eliminated, so the mechanical efficiency is high, the cost is low, and the performance is stable.2, with anti-card maintenance, when the drill is stuck, the motor is not easy to burn, the reducer is not easy to damage.
