Many swellex bolt are made of strong metals such as steel. Others are made out of plastic and designed to hold metal screws in place when connected to brick or concrete. Most come in the shape of bolts or screws and can be drilled into porous surfaces with ease. Various sizes are available for use in different types of construction projects.

Aug 2, - offers a range of accessories for Swellex expandable rock bolts to suit a variety of applications. The most common components are 

Product Description Water Swelling Friction Bolt is made by high strength welded tube folded itself and welded to seal at both end of bolt. Working principle: When the bolt is used in the hole, the bush with a hole is connected with a chuck of a high-pressure water pump. Start the pump and inject the water into tube, Contact Now

Swellex Rock Bolts tube are used to control the roof fall of the fully mechanized mining face, and can also be used in the construction of 

Swellex rock bolts offers a versatile portfolio of rock bolts that provides reinforcement solutions for ground conditions varying from easy to very difficult. With three typical capacity ranges, at 120 kN, 160 kN and 240 kN, the Swellex rock bolts can be used in most reinforcement and support applications. They can also be used

grouted bolts as well as swellex bolts will mainly be analyzed in the thesis. In the following, four constitutive models developed for the design of rock-bolt system based on analytical methods will be discussed. In is of great importance to utterly acquaint with those models involving the rock-bolts, rock mass interaction. 3.
