Concrete Core Drilling Machine

Concrete core drilling machine is also known as asphalt coring equipment, pavement core drilling machine. Road core drilling equipment adopts a gasoline engine as power, and it is suitable for non-powered places and large diameter engineering. The drill rig adopts high-speed cutting technology, and it can match with thin walled diamond drill bits.

Main Structure:

The structure of the coring machine is very simple. It consists of three parts: a bracket, a walking device, and a drilling rig. The bracket mainly supports the rig. Three wheels make walking more convenient. The handle can adjust drilling speed.

Features of Asphalt Coring Equipment:

  1. Adopts double-column structure, spiral feeding method.
  2. Has the advantages of good stability, simple and labor-saving operation.
  3. Beautiful appearance, strong and durable, easy to start.
  4. High drilling efficiency, good hole formation quality, no damage to the road.
  5. Uses ultra-wear-resistant chromium column, service life is 5 times of ordinary material.
  6. High-grade aluminum thickened walking wheels make walking more brisk and stable.
  7. Adjusts the height of the four bottom angles for drilling in various sites.
  8. Uses ultra-high finish ball screw and thread mother, makes the rise and fall particularly smooth and labor-saving.

Applications of Concrete Core Drilling Machine:

There are two main applications for road coring machine. One is for drilling on the horizontal plane, which is suitable for drilling in bridge and integrated building pile foundation, installing spike and road pile, etc. The second is for coring, which is suitable for a test in pavement, and it has been widely used in testing centers in various places.

Why Drill Cores in the Bridge?

Bridge handrails and traffic safety bars are designed to protect people’s safety, they need a certain depth of holes to support, otherwise, they are easy to fall. The purpose of the bridge guardrail is to prevent out-of-control vehicles from getting out. It also has the functions of beautifying the bridge construction. During the construction of the guardrail, the engineer should grasp the information on various facilities accurately, especially the exact locations of various pipelines. No damage to underground facilities is allowed during construction. When the drilling core is too deep, the column cannot be pulled out for correction. It needs to pull out the rest, and consolidate the foundation, or adjust the position of the column.

Why do a Coring Test?

For new roads, the engineer will check whether the road is qualified. So how does it reach the standard? Workers usually adopt road coring methods. It will test the sample to determine if the road is eligible. Core testing items for concrete pavement mainly include pavement thickness, compaction, flatness, anti-sliding, and water seepage performance. These have a greater impact on the strength and durability of asphalt pavements.

How to Operate Road Core Drilling Machine?

  1. Install an appropriate asphalt drill bit.
  2. Move the drill machine to the workplace. Fix the drill hole with expansion screws, and adjust the anchor screws, so as to make the drill rig stable. Or you can fix the core drilling machine with a sufficiently heavy baseplate, in order to prevent it from moving.
  3. Connect the water source, and check if the water is flowing out.
  4. Start the generator and turn on the circuit switch.
  5. Rotate the handle, drill bit touches the road and drills coring. When the depth is about 10mm, the handle can be pressurized to speed up the rotation.
  6. After coring, you can keep rotating and raise the drill bit. When it is about 5mm away from the road surface, you can turn off the power.
  7. Remove the fixing bolts, and remove the drilling sample with clamps.

Note:

  1. When the concrete core drilling machine is drilling, the feed speed should be uniform, about 3 ~ 5cm / min. If the drill bit is stuck, the operator should reduce speed appropriately. It needs to raise drill bit if necessary and then drill slowly, so as not to damage the drill and machine.
  2. During the drilling process, when the motor temperature exceeds 70 ℃, reduce the loading force and replace a new drill bit.
  3. Prevent the drill from hitting hard objects, and avoid damaging the drill bit.

Concrete core drill for sale can drill concrete, cement, asphalt pavement, and other substances. It has widely applied for drilling and coring in the fields of construction engineering and building quality inspection. The thin-walled diamond core bit can directly drill concrete and asphalt pavement, and engineer can test the core sample. This method is widely recognized as a relatively reliable method for detecting concrete road.

Apart from cement core drill, YG machinery also includes rock drill rig, crawler core drilling rig. Rock drilling equipment is a high-efficiency borehole drilling equipment. it has a wide range for drilling hole, broke concrete or cement, dismantling walls. Rock drilling tools are ideal for mining, energy exploration, road construction, and other blasting engineering. Core drilling rigs can explore of metal and non-metal solid minerals. In addition, they also apply for oil and gas field surveys, and water well drilling.
