Shotcrete Machine Rock Bolting and Shotcreting Role

At present, the output pz-7-type spraying machine has been widely used in the engineering and construction industry, pz-7-type spraying machine it is a new type of spraying machinery and equipment, people in the construction industry, the product has a very high concern. Therefore, Xin Sheng too for the birth of new products, If you compare the broken rock, then you can also use the screen to pull anchor block between small rock, reinforced concrete sprayed layer, assisted spray anchor support. Accordingly, increasing the role of pz-7-type spraying machine, interlock, complex and action, so that end we made the following analysis: First, increase the role of: Promptly following the roadway to be opened spray anchor support, because of the uneven surface of the surrounding rock fill, eliminate stress concentration caused because the rock face is not the commentary, to avoid excessive concentration of the stress surrounding rock damage caused. Second, the interlocking action: This role is to be split rock fissures bonded together if a piece of living Shifa Sheng slip crag rock fall, is caused by rock near Cascade, the successive loss of stability, resulting in a wide range of roof fall or spalling. If this problem can be timely open roadway bolting and shotcreting, bolting and shotcreting bond strength and shear strength is resistant to local damage of surrounding rock to prevent individual Granville rock live rock slip and fall, thereby maintaining Wai Stability of rock. Third, complex, and action: The role of the surrounding rock and support form a complex joint support surrounding rock, it can put the stability of high rock and their ability to support themselves, and the formation of a mechanical system to work together to solve the stent negative bear weakness question.
