Useful Tools

The proportions of bentonite solution for different types of soil are very important, since a significant impact on the success of the work on laying pipe. Working platform should be provided with water, ie, either on-site in the area is available at the fire hydrant or water supply is provided by mobile. Another essential tool for work – welding machine. For welding and subsequent pulling of pipes HDPE necessary quality welding equipment. Installing drives off the trawler and its course is set at the work site with the rear stabilizers and a system anchoring. Construction of underground communications technology horizontal directional drilling (HDD) construction of underground utilities on the technology of horizontal directional drilling (HDD) is a three- phases: drilling a pilot hole, a progressive increase of the well, pulling the pipe.

Drilling of pilot hole drilling a pilot hole made by the drill bit. In front of the rig head with a bevel cutting tool is installed. Inside the drill head is a probe of the location. At the expense of the bevel and the probe is managed by drilling. Control over the location of the drill bit carried out by means of locations consisting of a receiver (radar), which receives and processes signals integrated into the body of drill bit of the transmitter (the probe) and monitor the operator at the facility, duplicate readings locator. The operator of the locator should be on the surface of the drill head with the tip located in the ground. To monitor the radar display information about the situation on the clock, slope and depth of the probe.
