High Precision Rock Drill Rods High Torque Resistance For Bench Drilling 

Round rods are generally lighter than hexagonal rods and are normally used in extension drilling applications.

With the longer steel tending to be larger in diameter, conventional extension steel is characterized by a duplicate thread on each end of the steel.,

How does the water from the well come from

The reason why groundwater seeps from the cracks in the crust is that there are more or less gaps in the soil and rock on the surface of the crust. These gaps are the places where groundwater is stored, just like sponges absorb water. As the rock and soil filter the water, the groundwater is cleaner, and the groundwater flows in the rock and soil, from which a large amount of minerals are obtained. Therefore, well water is often the ideal drinking water.

Water wells are engineering structures mainly used for groundwater exploitation. The wells we see in our life are usually vertical, but they can not only take water vertically, but also be inclined and combined in different directions. Generally, we dig wells in our daily life, which can be used for water intake and irrigation. It can also be used to hide or store something.

Well is of great significance to the development of human civilization. Before the emergence of wells, human beings lived by water and could only live in places with surface water or springs. The invention of the well expanded the scope of human activities.

Generally, we can see circular tube wells in rural areas, which are used for a long time. It is believed that many families still have such wells, with a diameter of 1-2 meters. The depth is generally several meters to 20-30 meters. During construction, people can directly go into the shaft to excavate earth and rock. This well is only suitable for exploiting shallow groundwater.

The key points in the process of gas drilling include the following 6 aspects:

1. Select places as far away from sewers, sewage pipes and river banks as possible.

2. The well must be lined with bricks in time, and the deeper the well is, the more timely the lining is to prevent collapse.

3. When culvert pipe is used as liner, it can be dug to the depth at one time before pipe laying, but the soil must be used in geological places where collapse is not easy.

4. The depth of well drilling can only be stopped when there is obvious water trace in the soil below.

5. Clean and non weathered stones or large stones must be used for back sealing.

6. All processes must pay attention to safety, especially the excavation personnel below must wear safety helmets. When reaching a certain depth, there must be equipment to press air down from above. In case of collapse, evacuate immediately.
