Reinforce anchor pole.
To achieve the above object, the utility model provides a kind of bridge with anchor pole is reinforced, including hollow and open-topped
The body of rod, the post are connected with the cone-shaped drill bit that outside diameter is more than shank diameter, and the body of rod is uniform from top to bottom
Several cyclic annular fixed blocks with body of rod arranged concentric are connected with, the diameter of the fixed block is less than the outside diameter of drill bit, institute
Stating fixed block circumferentially has cyclic annular groove body, the circumferentially distributed slurry outlet for having several to be penetrated through with body of rod inner cavity in the groove body bottom, institute
It states and fixed plate of the bending in semi-annular shape is covered on slurry outlet, the fixed plate prolongs its circumferential both ends respectively positioned at slurry outlet
Above and below, wherein one end above slurry hole is hinged on groove body bottom, the dead plate upper end is apart from groove body upper side wall
Distance be more than fixed plate inner wall radius and less than fixed plate exterior radius, the depth of the groove body is more than fixed plate exterior radius
Less than the outer diameter of fixed plate.
Anchor pole is drilled into pontic by more than structure by drill bit, and by the open top end slip casting of anchor pole, slurries are from going out
It is injected into inside pontic in slurry hole and wraps up the body of rod, fixed plate is impacted in slurry injection process, fixed plate flip-over is beaten
It opens, by fixed block and fixed plate and the good contact of slurry, ensures that anchor pole is reliably connect, and pass through multigroup pulp with bridge
Hole bore inner is filled into full slurry so that anchor pole reaches good with slurry and contacts, in anchor pole rotation process, fixed plate button
It closes inside the groove body of fixed block, prevents fixed plate and pontic friction damage, also avoid fixed plate expansion that anchor pole is interfered to be drilled into
In pontic, pass through the restriction to fixed plate and groove body upper side wall distance so that when fixed plate is opened, the back of fixed plate leans against slot
In about horizontality on body upper side wall so that fixed plate cannot be rotated further.
Preferably, at least one diameter guide sleeve identical with drill bit outside diameter is provided on the body of rod.By leading
To set and with drill bit fixing anchor bar, prevent anchor pole swing cause rotation direction hair change.
Preferably, the annular seal plug in frustum body with body of rod arranged concentric is connected on the body of rod, it is described
Sealing-plug is located at the top of fixed block and guide sleeve.Prevent slurry excessive by sealing-plug.
Preferably, being fixedly connected on the body of rod, card is bad, the bad upper surface for being fitted in sealing-plug of card.Pass through snap ring
Fixing seal plug, prevents sealing-plug from play occurring upwards in stress.
Preferably, there is through-hole that is being penetrated through with body of rod inner cavity and tilting upward on the drill bit.Pass through through-hole so that slurry
Drill bit is wrapped, further increases contact surface, reaches good connection effect.
The beneficial effects of the utility model are：The utility model can carry out sufficient slip casting to armature boring, ensure entire
Anchor pole and the good connection of bridge, greatly improved whole fastness；Fixed plate inside and outside can turn down, that is, ensure that and slurry
Good contact is also prevented from fixed plate and pontic friction damage, while avoids fixed plate that anchor pole is interfered to be drilled into pontic.
