Background technology
Colliery tunnel support technology is the key technology in coal mining.Keep adjoining rock stability, control roadway deformation and destruction is to realize mine safety, the essential condition efficiently produced.Along with mine develops both in depth and in breadth, roadway support issues shows more and more prominent.BOLTING TECHNOLOGY TO COAL ROADWAY quickly grows in recent years, it has also become mine realizes the supporting technology that high-yield and high-efficiency is indispensable.
The current anchorage style of suspension roof support has the anchorage styles such as end anchor, the extensible bolting and full length fastening, in order to improve supporting effect, reduces the tunnel absciss layer at initial stage, deformation, and most of end anchors and the extensible bolting anchor pole all apply pretightning force.Bolt, due to complicated construction technique, applies pretightning force difficulty big, is generally not added with pretightning force, it is impossible to realize full-length prestress anchoring.
The prestressing force full length fastening of current common bolt is generally adopted two kinds of forms.One is to adopt fast slow hardening resin explosive roll to realize, but in actual applications, when aperture ratio is constant owing to powder stick skin easily forms spherical conglomeration under anchor pole pushing tow rotates, anchor pole is directly hindered to advance, cause that rockbolt installation is not in place, therefore often adopt increase bore diameter mode to solve, but there is again the problems such as aperture ratio does not mate, and bond effect is undesirable.Another is that anchor pole uses resin explosive roll to fix, and non-strength of holing knot section adopts big drill sleeve hole, and along anchor rod body arranging exhaust air pipe, rockbolt installation grouting plug, after rockbolt installation completes, slip casting completes prestressing force full length fastening.
Big based on current prestressing force full length fastening technology difficulty of construction, the problems such as construction technology is complicated, this utility model provides provides the prestressing force Bolt that a kind of method is simple, cost is low, workload is little and construction technology change is little.
