Embodiment 1

[0016] The invention discloses a construction method for roadway full-anchor support, which has obvious effect in the roadway support with large section, stress concentration area, high pressure, roadway retention along the gob, and high repair rate, and can also be used for the intersection of electromechanical chambers point, permanent roadway support.

[0017] Concrete support method step of the present invention is as follows:

[0018] 1). According to the design requirements of roadway support, drill anchor holes for anchor rods or anchor cables on the broken surrounding rock around the roadway. Hollow anchor rods or anchor cables are used for anchor rods or anchor cables.

[0019] 2). Install the anchor rod or anchor cable into the anchor hole, and apply pre-tightening force to the anchor rod or anchor cable, so that the anchor rod or anchor cable is fastened in the anchor hole. After fixing the anchor rod or anchor cable to the anchor When in the hole, a metal mesh and...

Abstract

The invention discloses a construction method of a roadway full-anchor support. The construction method comprises the following steps of (1) fixing of an anchor rod, (2) whitewashing of an anchoring face, (3) maintenance of the anchoring face, (4) manufacturing of grouting slurry, (5) grouting and (6) maintenance of a roadway. Grouting reinforcement is conducted on broken surrounding rock so thatthe broken surrounding rock can form a multi-layer arch to improve the crush resistance and breaking resistance, the service life of the roadway is prolonged, the repair rate is reduced, the labor intensity is relieved, and the cost is saved.

Description

technical field [0001] The invention relates to a roadway support method, in particular to a construction method for roadway full anchor support. Background technique [0002] At present, in the support of underground roadways, the combination of anchor nets, U-shaped sheds and shotcrete is often used to support the roadways. This support method is not only complicated in process, difficult in construction, labor-intensive for workers, waste of materials, affecting construction progress and efficiency, and high in cost, but also because there are often broken high-stress surrounding rocks and surrounding rock cracks around the roadway, gravel does not If it is solidified, it is easy to cause a roof fall accident, and then cause personal injury. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a construction method for roadway full anchor support, use this method to support the roadway, solidify the broken surroun...
