GY200 Core Drilling Rig Product Advantages:
1. It has an automatic oil pressure feeding mechanism to improve
drilling efficiency and reduce workers' physical labor;
2. The ball clamping mechanism is used to replace the chuck, which
can reverse the rod without stopping the machine, which is
convenient, safe and reliable;
3. Equipped with hole bottom pressure gauge to indicate the
pressure, which is convenient to master the situation in the hole;
4. The handle is centralized and easy to operate;
5. Compact structure, drilling rig, water pump and diesel engine
are installed on one base, occupying a small area of the airport;
6. Light weight, strong decomposability, easy to move, suitable for
working in plain or mountainous areas.
GY200 Core Drilling Rigs Product Applications:
1.The drilling rig is suitable for general survey, geophysical exploration, road and building exploration, etc.
2. Alloy, steel sand and steel particle bits can be selected for drilling according to different formations.
3. It can drill sandy clay and bedrock of grade 2-9.
4. The rated drilling depth is 100m, and the depth shall not exceed 120m. The rated opening diameter is 110mm, the allowable opening diameter is 130mm, and the final hole diameter is 75mm. The drilling depth depends on the formation conditions.
Core Drilling Machine Principle
The principle of core drilling machine is basically the same, and the main components are drilling machine, drill pipe, drill bit, etc. The drill provides power to drive the drill pipe and drill bit to drill and obtain deep core samples. According to different depths and strata, corresponding to different types of drilling rigs,
The specific steps of soil sampling method are as follows:
1. Distribution: samples shall be taken according to the soil type and the distribution of crop varieties, and according to the different soil fertility. The sampling points are distributed in zigzag or snake shape, which should be as uniform and random as possible.
2. Determine the sampling position and depth: the sampling position and depth shall be determined according to the thickness of the cultivated layer. Generally, the sampling depth is 0-20cm
