This testing machine is a core drilling device specifically designed for tunnels, concrete walls, or dams. It can perform deep core sampling underground or inside structures for rock or concrete sample collection and strength testing. It features electric drive, easy operation, and reliable accuracy, and is suitable for tunnel inspection, geological exploration, and engineering quality assessment.

Electric tunnel inspection deep hole coring test machine

Model:LJLMR-1

I. Product Introduction

This machine conforms to GB11818-89"Technical Requirements for Concrete Core Drilling Machines"and ISO 1920-6:2019—Testing of concrete—Part 6:Sampling,preparing and testing of concrete cores.Furthermore,this drilling rig can also perform core drilling on other non-metallic brittle and hard materials,such as refractory materials,ceramics,glass,and rock.This electric core drill is equipped with a built-in external adjustable safety clutch;it also has an overload protection switch that automatically disconnects to protect the drill in case of jamming or excessive torque;and it features a double insulation structure for safety and reliability.

It is mainly used for core drilling in hardened concrete structures such as buildings,highways,airports,docks,and dams.It features simple operation,easy relocation,and accurate core drilling.The core sample has a smooth surface and will not cause accidental damage to the core sample,making it suitable for use by highway transportation departments,construction departments,and related colleges and universities.
