Manufacturer Of Soil Testing Drilling Rigs For Environmental Monitoring

ST30 impact drill rubber track drilling rig

The ST30 impact drilling rubber track drilling rig It is a lightweight and multifunctional micro engineering drilling rig with high torque, used for geological exploration sampling in industries such as industrial and civil construction, bridges, railways, highways, and hydropower. Its structure is compact, small in size, light in weight, with two speed changes, easy to transport and move, and can achieve complete drilling and sampling. The diameter of the borehole is 46-91 millimeters, and the depth of the borehole varies under different conditions, such as 15-20 meters for soil layer with a diameter of 91; When the rock diameter is 91, it is 10-15 meters. The drilling angle is 0-90 °, the drilling torque is 120N. m, and a voltage of 380V is used

ST30 Borehole Drilling Machine Technical Data:

Performance characteristics

It can be applied to environmental monitoring and protection, and can use impact drilling and spiral drilling techniques to quickly obtain reliable underground information without damaging the underground soil structure. It is possible to obtain undisturbed soil samples from the surface to deep layers, and different drill rods and drilling tools can also be used to set up small-diameter groundwater observation wells. During the drilling process, mud and other cleaning media are not used, and the waste generated during drilling is 70% -80% less than conventional drilling. It has the characteristics of high construction efficiency, good fidelity of rock and soil samples, less environmental pollution, compact structure, good maneuverability, and construction safety.

Proper use and maintenance of impact drilling environmental sampling rigs can not only ensure operational efficiency and sampling accuracy, but also extend equipment life and reduce the risk of failure. The following are specific operation guidelines and maintenance points:

1, Preparation before use

1. Site survey and equipment inspection
Terrain assessment: Ensure that the drilling rig parking area is flat and solid, and avoid working on slopes or soft ground to prevent equipment from tilting or sinking. If the ground is uneven, use padding or sleepers to level the machine body.
Power and gas source inspection:
Fuel powered models: Check the diesel/gasoline volume and oil level to ensure that the fuel grade matches the ambient temperature (such as using low pour point diesel in winter).
Motor type: Confirm that the power supply voltage is stable (e.g. QZ-30S requires 380V voltage), and that the cable is not damaged or has any potential leakage hazards.
Pneumatic model: Connect the air compressor, check if the air pressure meets the equipment requirements (usually 0.6-1.0MPa), and ensure there is no air leakage in the gas pipeline.
Preparation of drilling tools and accessories:
Select appropriate drilling tools based on the type of formation (such as spiral drills for soil layers and impact drilling tools for fractured layers), check the wear of the drill bit, and ensure that the inner wall of the sampling cylinder is smooth and free of deformation.
Prepare commonly used tools such as wrenches and screwdrivers, as well as spare sealing rings, O-rings, and other vulnerable parts.

2. Installation and commissioning

Modular assembly: Install the mast, power head, drill pipe and other components in the order specified in the manual, ensuring that the bolts are tightened (using a torque wrench to tighten to standard torque) and that all interfaces are well sealed.
No load trial operation:
Start the power system, run at low speed for 5-10 minutes, and observe whether the instrument panel parameters (such as oil pressure, air pressure, and speed) are normal.
Idle the drilling tool, check if the rotation direction is correct (usually clockwise), if the impactor moves smoothly, and if there are any abnormal noises.

Alignment and verticality calibration:
Use a compass or laser level to adjust the verticality of the drilling rig, ensuring that the drilling deviation is ≤ 1% (special projects require calibration according to design requirements).
Align the sampling point markings, fix the drilling rig base, and if necessary, use ground anchors or counterweights to enhance stability.
