Preparation Work Before Hydraulic Dth Drill Rig Construction.

  The construction of hydraulic down-the-hole drilling rigs has the characteristics of fast hole formation, high quality, no noise, and no pollution. Because of its unparalleled advantages in the construction of cast-in-place piles, it is favored by more and more construction units. Therefore, the current price segment Drilling rigs are the main force in underground engineering construction. 1. Construction site:  hydraulic DTH Drilling Rig  for pile foundation construction. In the preliminary preparation stage, the construction site is required to be high. Due to the heavyweight of the rotary drilling rig, the operation of the rotary drilling rig requires the machinery to remain stable, so the operation The site reaches a certain bearing capacity. If the working surface is a relatively soft stratum, the supporting layer should be backfilled so that the site can carry the  hydraulic DTH Drill Rig , and the cranes (above 25t), concrete filling trucks and other eq...

What are the reasons for rig track delinking and how to deal with it?

For rig operators, track disconnection is a common problem. For rigs, occasional off-chain is unavoidable, because the working environment is relatively harsh, and crawling into the soil or stones will cause off-chain. If the rig is often off-chain, then it is necessary to find the cause, because the off-chain of the rig can easily lead to accidents. What are the reasons for the rig off-chain? Today,  water well drilling rigs supplier  will briefly talk about the common reasons for off-chain. In fact, there are many reasons for the rig to be off-chain. In addition to impurities such as track entering the soil or stones will cause the rig to be off-chain, there are also faults in the walking ring gear, de-sprockets, and chain protectors that will cause off-chain. In addition, improper operation will cause the rig to be off-chain. 1. Tension cylinder failure caused chain disconnection. At this time, you should check whether the tensioning cylinder has forgotten to butte...

How to Choose Drill Bits In Borehole Drilling Machine Construction?

  1. The main function of   Advanced Crawler Mounted DTH Drilling Rig  is to dig holes on the surface. Due to the different depths of the pile holes to be constructed, various terrain structures will be encountered during drilling. It can be roughly divided into the following categories: (1) Clay: Use a rotary drilling bucket with a single bottom. If the diameter is small, use a two-part bucket or a bucket with a soil unloading plate. (2) Silt, low-cohesive soil layer, sandy soil, and poorly cemented pebble layer with a small particle size can be equipped with a double-bottom drilling bucket. (3) Hard clay: Use a rotary drilling bucket with a single inlet (single and double bottoms), or a bucket tooth straight screw. (4) Frozen soil layer: Bucket-tooth straight spiral drill bucket and rotary drilling bucket with low ice content can be used, and cone spiral drill bit with high ice content can be used. It should be noted that spiral drill bits are used for soil layers (exce...
