Abstract

The invention discloses a concrete drilling and coring machine for constructional engineering quality supervision, and relates to the field of constructional engineering. The concrete drilling and coring machine aims at solving the problems that the coring operation of an existing drilling and coring machine during constructional engineering quality supervision is more in dust and a drilled sampleis inconvenient to take out. According to the technical scheme, the concrete drilling and coring machine comprises a bottom plate, vertically distributed threaded rods are arranged at the four corners of the bottom plate in a threaded penetrating mode, supporting legs are rotatably mounted at the bottom ends of the threaded rods, handles are fixedly connected to the top ends of the threaded rods,a mounting frame is fixedly connected to the top end of the bottom plate, and a driving motor is fixedly mounted in the mounting frame. The concrete drilling and coring machine is novel in structure,can limit and protect drill bits with different sizes, improves the drilling stability, can perform effective dust fall treatment in the drilling operation process, can conveniently take out a drilled sample after the drilling operation is completed, shortens the drilling sampling time, improves the working efficiency, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a concrete drilling and coring machine for quality supervision of construction engineering. Background technique [0002] The drilling and coring machine is a mechanical device using a Honda gasoline engine. Concrete drilling and coring machine mainly has two purposes, one is for horizontal drilling, suitable for road stud installation, road pile installation, bridge drilling operation rules, integrated house pile foundation drilling, etc., has been widely used in traffic engineering companies , China Railway Group, Integrated Housing Company and other units; the second is for coring, which is suitable for pavement coring for testing and has been widely used in testing centers around the world. [0003] During the use of traditional drilling and coring machines, large dust will be generated, which will affect the health of the sampling personnel, and it is inconvenient to...
