Product Advantages:
1. With oil pressure automatic feeding mechanism, high drilling efficiency.
2. Centralized handle, convenient operation, safe and reliable.
3. The drilling rig, shifting base and diesel engine (or motor) are all installed on the same underframe, occupying a small space.
4. Light weight, strong decomposition, easy to move, suitable for plain and mountain work.
Why is the water well drilling rig not suitable for use in rainy days?
After the well is completed, it is necessary to pump water to check the results. Under normal circumstances, a large draw down pumping can be done. The stable duration of the water level shall not be less than eight hours, and the water flow of the dynamic water level of the well shall be measured at the same time. The well drilling project shall ensure the smooth drainage of the construction site, so the rainy season shall be avoided. When working while excavating, the excavation slope shall be determined according to the physical and mechanical properties of the soil layer, generally 1:1.5, and there shall be a certain distance from the toe of the spoil slope to the upper opening of the excavation. For large wells with water inflow from the shaft wall, the water inlet hole and inverted filter layer of the shaft wall must be arranged according to the design requirements, and the water inlet hole shall be prevented from being blocked during construction. The filter material enclosure at the aquifer shall meet the requirements, the backfill shall have a certain super elevation, and the frozen soil in the backfill in winter shall not exceed 15%.
Matters needing attention during the drilling process of drilling and coring machine
What should we pay attention to when drilling?
1. When drilling at ordinary times, many people will not notice the water level difference and mud concentration, which can play a protective role;
2. It is better to operate the drilling while it is hot, and it is better not to stop for a while before continuing the operation;
3. During the drilling process, control the drilling speed and slow down the drilling according to the soil quality and other conditions;
4. Strengthen the inspection of pile position and hole formation during drilling. During the final hole formation, check the position, hole diameter, shape, depth, deflection and soil quality of the pile at the bottom of the hole. After passing the inspection, clear the hole immediately, hang the reinforcement cage and pour concrete.
