Disk, the internal diameter at abnormity nut rear portion are less than the outer diameter of circular coupling plate, and abnormity nut front is equipped with suitable with hole sealing device installing zone
The internal thread matched.
It is arranged with supporting plate and fastening nut on the hole sealing device installing zone successively from front to back, supporting plate is located at expansion nut
Rear.
The circular coupling plate front end is equipped with seal washer.
The section of the anchor pole front is regular hexagon, and the adjacent side of anchor pole has and only there are one sides to be equipped with air inlet
Hole, anchor pole have most 1 air admission hole on the arbitrary section perpendicular to its axis.
The connecting tube is " L " shape.
The branch pipe is divided into four row and is circumferentially uniformly distributed around gas collecting tube.
The utility model is simple in structure, easy to use, can be to the small model in top plate top by the air admission hole on the side wall of anchor pole
It encloses interior gas and carries out extraction, prevent gas from causing local gas to gather by armature boring leakage, while anchor pole can also be to coal
Mine carries out normal supporting, reduces the quantities of gas pumping, short construction period is quick；Make extensively at present relative to coal mine
Polyurethane sealing of hole mode, gum cover sealing of hole facilitate rapid, and at low cost, reliability is high, are not shaken and coal petrography wall deformation effect,
Drilling can be kept to seal for a long time；The extraction simultaneously of multiple anchor poles can not only be saved material but also reduce quantities by current divider.
