爆管锚杆之所以能沿炮孔全长锚固,是山于管段中炸药爆破能使管段扩展造成的.爆管锚杆的安装方式如下:在管段中放入带有电雷管的炸药线(一根或几根导爆线),管缝隙填充砂、水类惰性料.管口用木楔封闭,防止填充料流失,同时也将导爆索固定在管段的中心线位置.然后将制备好的爆管中描杆放入炮孔中,连接电力爆破回路,并对需要数目的锚杆进行一次引火起爆.
The reason why the pipe bursting anchor can be anchored along the entire length of the blast hole is that the blasting of the mountain in the pipe section can cause the expansion of the pipe section.The installation of the bursting pipe bolting is as follows: Inserting the explosive charge with the electric detonator in the pipe section One or several detonating lines), tube gap filling sand, water inert material.Muzzle closed with wedge to prevent the loss of filler, but also the detonating cord fixed in the center line of the pipe section.And then prepared Burst pipe in the stave into the hole, connect the electric blasting circuit, and the number of bolts required for a pilot detonation.
