Description

[0002] Wall drilling in engineering construction is a work needing meticulous operation and professional skill, and its purpose is to install fixing parts, pipelines or other equipment. The quality of this work is directly related to the stability and safety of subsequent installation, so it must be strictly operated according to the specification during construction. First of all, detailed inspection of the wall surface is required before construction to determine its material (such as concrete, brick wall, light partition wall, etc.) and internal structure (whether there are steel bars, water and electricity pipelines, etc.) to avoid damaging concealed works or affecting the load-bearing capacity of the wall. Choose the appropriate drill bit according to the type of wall, and adjust the appropriate speed and force.

[0003] In the prior art, water drilling machine has unique advantages in wall drilling operation. It lubricates and cools the drill bit with cooling water or liquid, which not only effectively reduces the heat generated by friction and prolongs the service life of the drill bit, but also significantly reduces the noise and dust pollution during drilling, making the construction environment cleaner and safer. However, this process also has some limitations in practical application, for example, water drilling machine produces a large amount of wastewater during drilling, which usually flows along the wall, not only polluting the ground, but also seeping into the wall gap, making the later cleaning work tedious, and even affecting the appearance of the wall. The traditional water drilling machine needs to be operated by hand, and the drill bit is easy to slip when drilling on smooth and hard walls such as ceramic tiles and marble, resulting in hole deviation.
