For rig operators, track de-chaining is a frequent problem. For drilling rigs, occasional disconnection is unavoidable, because the working environment is relatively harsh, and the crawler tracks enter soil or stones will lead to disconnect ...
At present, the commonly used technical methods to improve the vertical bearing capacity of cast-in-place piles include bottom expansion method and post-grouting method of bored cast-in-place piles. Bottom drilling method In the same formati ...
The biggest difference between pneumatic drilling rigs and ordinary drilling rigs is the drilling method. Ordinary drilling rigs usually use rotary drilling, that is, relying on the rotation of the power head to drive the drill pipe and dril ...
The newly purchased water well drilling rig generally needs to go through a running-in period of 60 hours. A water well drilling rig in the break-in period has the following characteristics: 1. Fast wear and tear 2. Poor lubrication 3. Easy ...
When the pile driver suddenly tilted and misplaced during the construction of the pile driver, and at the same time the pile hammer jumped up and the pile body rebounded, the construction had to be stopped. There are several reasons for the ...
1. Introduction of water well drilling rig crawler The crawler of the water well drilling rig is composed of a crawler shoe and a crawler pin. The track pins connect the track shoes to form a track chain link. There are holes at both ends o ...
How to improve the production efficiency of hydraulic water drilling rigs? The following small series illustrate the use of preventive measures. 1. After the drill bit of the hydraulic well drilling rig is drilled into the structure, the ce ...
1. Damaged drill pipe: 1. In most cases, the fracture of the drill pipe belongs to the friction between the drill pipe and the hole wall, so that the wall thickness of the drill pipe is reduced, and the strength is too weak to cause the dri ...
Drilling is the use of mechanical equipment to drill holes in the formation. According to the rock breaking method and the type of drilling tool, it can be divided into drilling technology and rotary drilling technology. In geological explo ...
