Often, existing concrete structures will need to be examined and tested to ensure the concrete remains of adequate strength and durability. This test is used to determine the compressive strength of a concrete core, which has usually been extracted from an existing structure. The value of compressive strength can then be used in conjunction with other measured properties to assess the condition of the concrete. Extraction of concrete cores, achieved by rotary drilling using a diamond tipped hollow barrel, serve as a means of taking a sample of concrete which can then be used to determine various physical properties, but most commonly compressive strength. Cores can generally be extracted from wherever access allows, and would include floor slabs, walls and columns. 10cm diameter cores, generally afford the minimum diameter required for a representative sample and require less reinstatement than larger diameter cores. 15cm diameter cores will generally give more representative samples than smaller diameters but require more reinstatement.

In July 2015, Xinjiang Jiugan Peng Mining Co., Ltd rented one EBH120 roadheader machine for the construction of Wuqia county copper mine tunnel. The tunnel had copper and a small amount of limestone, the roadway section is 18 square meters, the average footage is about 6 to 7 meters, slightly uphill. Through our training, the customer’s team learnt the way of use and maintenance quickly (earlier they used to dig with blasting and driving, not using a roadheader machine). Now the equipment is running very well and the accident rate is low, the footage efficiency has increased 5 to 7 meters per day.

We are a proud Manufacturer, Trader and Supplier of Pavement Core Drilling Machine. What make our Pavement Core Drilling Machine stand out is its attribute if being a diesel engine that is a tremendously powered road building drill. An exclusive fact of our Pavement Core Drilling Machine is that it has been specifically designed for accomplishing the purpose of drilling test cores from or holes in roads, airport runways, bridges etc. Our Pavement Core Drilling Machine is giving the best results for vertically down coring applications.  Components The Machine comprises of two vertical support columns, which carry the Drill headEngine assembly with the help of screwed spindle. 5 HP diesel engine with pulley mechanism works with minimum vibrations. Double precision bit advanced with screwed spindle, to provide a constant, accurate drill pressure, minimum core chipping & long bit life. The entire assembly is supplied on a rigid metal base with leveling facility. Technical Specifications Bit Diameter : Varying from 25mm to 150mmMaximum depth of core : 700mmDrill speed : 475 & 800 R.P.M.Guide Shafts : 50mm diaScrewed Spindle : 20mm diaWater Tap : 12mmDrill WrenchesWater Tank depending on the requirements

Product Code: EKE 368 It comprises: Percussion Hand Drill, 700 Watts capacity 1 No.Feed Assembly including screw and shaft 1 No.Anchor Bolts and Clamping Pliers 1 Set Core Case is the first innovation in Concrete core drilling. Connected to the core drill assembly with a flexible rubber coupling, the heavy duty, hand held, rotary drill easily produces cores upto 100 mm in dia without the use of cumbersome frameand feed. The Water Jacket surrounding the core barrel is flanged, enabling it to be clamped to the surface to be drilled. For added support, clamping pliers and anchors are supplied. A rubber O-Ring fitted with the flange seals the water jacket core barrel assembly against concrete surface, enabling the return flushing water containing the cuttings to be hosed away from the drill site. Water is fed into the upper water jacket nipple, from there the water flows, through a manifold, into the drill spindle and continues to the inside of the diamond core bit. A steady feed pressure can be maintained on the drill bit by turning the capstan wheel with one hand, while holding the electric drill steady on the coupling with the other. The drill feed assembly, common to all models, makes the systemadaptable to all core diameters with additional conversion kit. Core Case is a completely portable, self-contained system, easily carried by a person in a standard brief case. EKE 36801 Core Bit and Water Jacket, 25 mm dia x 75 mm long EKE 36802 Core Bit and Water Jacket, 3B mm dia x 100 mm longEKE 36803 Core Bit and Water Jacket, 50 mm dia x 100 mm longEKE 36804 Core Bit and Water Jacket, 75 mm dia x 100 mm longEKE 36805 Core Bit and Water Jacket, 100 mm dia x 100 mm longEKE 36810 Core Bit 50 mm dia x 200 mm longEKE 36811 Core Bit 75 mm dia x 200 mm longEKE 36812 Core Bit 100 mm dia x 200 mm long CAUTION Coring cannot be done if encountered by reinforcement steel, hence to be avoided. 2. Core bits larger than 50mm dia may be avoided if concrete with strength M60 is encountered, as this may overload the motor and damage the bit.
