Advantages Analysis of the Remanufacturing and Refurbishment of Rotary Drilling Rigs

In the field of building construction, rotary drilling rigs, as important basic construction equipment, have a high frequency of use and a high degree of wear and tear. With the continuous development of remanufacturing technology, remanufactured and refurbished rotary drilling rigs have gradually become the focus of market attention. These products, through professional repair and upgrading of old equipment, make their performance close to or reach the level of new products, while also having many significant advantages.

Five major advantages of rotary drilling rigs, do you all know?

Compared with traditional percussion or rotary drilling and mud circulation wall protection technology, rotary drilling rigs have many advantages in both technology and equipment.

Why are rotary drilling rigs so efficient at drilling holes?

In the field of basic engineering construction, rotary drilling rigs are highly regarded for their efficient and precise drilling capabilities. So, what is the mechanical working principle of a rotary drilling rig that allows it to quickly complete drilling operations under various geological conditions?

Construction Characteristics of Horizontal Directional Drilling

1. Directional drilling construction will not hinder traffic, will not destroy green space and vegetation, and will not affect the normal life and work order of shops, hospitals, schools and residents. It solves the interference of traditional excavation construction on residents' life, traffic and environment, and the damage and adverse effects on the surrounding building foundation.

Pipe jacking machine propulsion system

Main jacking cylinder: The main jacking cylinder is the main equipment of the main jacking device. It is customarily called a jack in engineering. It is the driving force of the pipe section. The main jacking oil cylinder is installed in the pipe jacking operation well and is generally evenly arranged on both sides of the pipe wall. The cylinder is mainly composed of a cylinder block, a piston, a piston rod and a seal. Most of the use of telescopic hydraulic drive piston double-acting cylinder form.

Features of cantilever tunnel boring machine

The cantilever TBM can only cut part of the tunnel section. To break the full-face rock, it is necessary to move the cutting head up and down, left and right, many times in order to complete the work. Can be used for tunnels of any cross-sectional shape.
