Trenchless directional drilling construction process-1 The directional drill crosses and controls the direction. In the process of pilot hole drilling, the wireless direction control system is used, and the ground beacon system is arranged on the center lines of both sides of the entry and exit poin

Requirements for supporting a lubricating mediumThe requirements for supporting a lubricating medium can be calculated according to the law of friction.Summary of friction lawIn addition to rolling friction, which is not discussed here, friction can be divided into:A) Adhesive friction (same as stat

Mud technology in trenchless constructionIf the blade foot is slightly larger than its size corresponding to the outer diameter of the pipe, it is possible to reduce the frictional resistance of the outer wall of the pipe. This prevents the upper layer from directly pressing on the tube body. As lon

Why should we formulate the "Code" for pipeline trenchless engineeringNow the use of trenchless is more and more widespread, so the problems that arise are increasing day by day. There is no corresponding standard specification for pipeline trenchless engineering, so the current pipeline trenchless

Trenchless technology is classified according to construction technologyTrenchless technology can be divided into: directional drilling pipe laying technology, escape shuttle pipe laying technology, pipe jacking tunneling and laying technology, pipe jacking pipe laying technology.Among them, the adv

Application of Trenchless construction in electric power constructionWith the rapid development of urban economy and the acceleration of urbanization, the number of power engineering construction projects is increasing. The use of power cables to transmit electric energy has a small footprint, does

How much is one meter for the Trenchles project Trenchless pipe jacking is widely used in the construction process, and the pipe jacking construction technology continues to develop rapidly and is actually applied in a large number of projects. How much is a pipe jacking project?With the continuous

The Cost of Trenchless At present, trenchless pipeline engineering is used in many constructions. This technology is also used by more and more people in modern society. Of course, before understanding a project, people will first understand its price, then What is the price of trenchless? Let's tak

Risk factors of pipeline trenchless engineering Construction is mainly to avoid risks. Nowadays, more and more pipe jacking are used, so it is necessary to conduct risk assessment of pipeline trenchless engineering. Let's talk about the risk factors of pipe jacking construction. Most of the risks of
