The concrete drilling coring machine is mainly used for two purposes. One is for drilling on the horizontal plane, which is applicable to the installation of road studs, road piles, bridge drilling operation procedures, and pile foundation drilling of integrated houses. It has been widely used in transportation engineering companies, China Railway Group, integrated houses companies and other units; The second is for coring, which is applicable to road coring for testing, and has been widely used in detection centers around the country.

More Information
Operate::
Preparations before use:1. Add 93# unleaded gasoline and lubricating oil. The amount of oil added can be based on the scale of the oil dipstick.2. Add lubricating oil to the column, and turn the feed handle and output shaft to check whether the feed and rotation are flexible and reliable.3. Prepare the water source.4. Check whether the screws in each part are loose.Installation:After the drill bit is aligned with the hole, lift the three walking wheels and let the base fall to the ground. When drilling small holes and the concrete strength is not high, the drilling rig can be fixed by the weight of the drilling rig. Iron blocks, concrete blocks, etc.) or two expansion bolts plus pressure rods (such as channel steel, etc.) to fix the drilling rig. The drilling rig must be fixed firmly and must not be shaken, otherwise the drilling operation cannot be carried out normally.Opening:After the above operations are completed, you can open the hole, install the drill bit, start the gasoline engine (see the gasoline engine user manual for details), put the water inlet pipe into the bucket, the bucket should be raised above the water pump, and then squeeze the air pump to inhale the water After the pump is filled with water, place the bucket on the ground. Turn the throttle to the maximum and start to gently crank the feed handle so that the drill bit touches the ground slowly. Drilling tips: first feed water and then drill, the feed speed should be slow, and the drilling pressure should be small. It is strictly forbidden to work without water, so as not to burn the drill bit and the water seal.Normal drilling:When the hole is drilled to a depth of 2-3 mm, it can be switched to normal drilling. At this time, the feeding pressure should be appropriately increased. The key to normal drilling: the feeding pressure should be moderate and uniform. The inlet pressure should be reduced. To do one listen and two check, listen to whether the sound of the machine is normal, and see if the orifice returns (takes) water.End hole:After reaching the desired depth and degree, the drilling can be stopped. The requirements for stopping drilling are: first turn off the machine and then turn off the water. If it is a deep hole, you cannot immediately lift the drill and stop the water. Instead, you need to punch the hole with water for a period of time. The purpose is to rinse the rock powder in the hole to prevent the rock powder. Precipitation leads to buried drilling, which makes coring difficult.
