Core drilling machineRotary drilling is a type of construction technology suitable for hole forming operations in building foundation engineering. It is widely used in municipal construction, highway bridges, high-rise buildings, and other basic construction projects, utilizing various drilling tools.

Core drilling machine works by rotating a hollow drill bit to cut a cylindrical core sample from the ground.

Core drilling machine has the following advantages: 1. High drilling efficiency 2. Accurate drilling depth 3. Clean and smooth drilling holes 4. Suitable for various materials 5. Easy to operate and control

The use value of core drilling machine is to drill holes in various materials such as concrete, metal, and stone for construction and industrial purposes.

The pressurization construction method of the core drilling machine mainly adopts the "combination of constant pressurization and jog pressurization". The constant pressurization mainly generates static load and provides constant pressurization force for grinding rocks, and the jog pressurization mainly forms A certain impact on the rock can achieve local fragmentation of the rock. These two methods are combined with each other to achieve rapid cutting of the rock. Due to the uneven softness and hardness of the rock, the rotational speed will change with the load, resulting in the alternation of speed and slowness during the drilling process, which also causes a certain impact on the rock, thereby achieving the effect of accelerating rock cutting.

The core drilling machine has a high degree of automation, fast drilling speed and high quality. The drilling rig is fully hydraulically driven and controlled by a computer. It can precisely locate the drilling hole, automatically correct the verticality of the drilling hole and automatically measure the drilling depth to ensure the maximum drilling quality. Its ergonomics are 20 times that of the circulating drilling rig, and the most important thing is that the quality and progress of the project are fully guaranteed.

The environmental protection features of the core drilling machine are outstanding, and the construction site is clean. This is because the rotary drilling rig excavates the soil through the drill bit, and then lifts the drill bit out of the hole through the Kai-style telescopic drill pipe and then unloads the soil. Rotary drilling rigs use mud only for wall protection, not for ballast removal. The mud used for hole formation is basically equal to the volume of the hole, and the mud can be used repeatedly after sedimentation and sand removal. At present, the sewage cost during construction has increased significantly in many cities. The use of rotary drilling rigs can effectively reduce the sewage cost and improve the level of civilized construction.

Core drilling machine is suitable for dry (short screw), wet (rotary bucket) and rock formation (core drilling). It has the features of high efficiency and multi-function. The rotary drilling rig is suitable for the soil geological conditions in most areas, and has a wide range of use, which can basically meet the use of bridge construction, high-rise building foundation and other projects.
