For achieving the above object, the invention provides a kind of blasting type anchor pole, it comprises: the body of rod, and it is the hollow tubular of upper and lower both ends open, and the lower end edge circumference of this body of rod offers several explosion grooves equably; Rendrock, it is filled in the lower end of the described body of rod and corresponding with described explosion groove; Be embedded with detonator in this rendrock, the payment to a porter of detonator extends upwardly to outside the upper end of the described body of rod from the inner chamber of the described body of rod; Backing plate, it is sheathed on the top of the described body of rod; And door, it is the T-shaped pipe of a both ends open, and the internal diameter of larger one end of this door is greater than the internal diameter of less one end, and less one end of this door is connected with the upper end of the described body of rod, described backing plate is pressed in side slope by larger one end.
Preferably, in technique scheme, less one end of described door and the upper end of the described body of rod are threaded connection.
Preferably, in technique scheme, the internal diameter of larger one end of described door is 2 ~ 3 times of the internal diameter of the described body of rod.
Present invention also offers a kind of mounting method of above-mentioned blasting type anchor pole, it comprises the steps:
The first, side slope gets out guide hole;
The second, carry out reaming to the lower end of described guide hole, to form the chamber that a diameter is greater than the diameter of described guide hole, and the radius of this chamber is greater than the length of described explosion groove;
3rd, described blasting type anchor pole is inserted in described guide hole, then ignites described rendrock, to open according to described explosion trench brace to make the lower end of the described body of rod and snap in described chamber;
4th, described backing plate is sheathed on the top of the described body of rod, and by described door, described backing plate is pressed in side slope; And
5th, in the described body of rod, chamber and door, fill full water cement mortar.
Compared with prior art, the present invention has following beneficial effect:
1, the present invention is blown the lower end of the body of rod by rendrock along explosion groove, thus the lower end of the body of rod is strutted, after filling cement mortar, the lower end of the body of rod and side slope and cement mortar produce larger jam power, thus the breakout capacity of anchor pole can be strengthened, ensure the safety of side slope.
2, the T-shaped shape of door of the present invention, and the internal diameter of its larger one end is 2 ~ 3 times of body of rod internal diameter, thus after filling cement mortar, backing plate is pressed in side slope surface securely.
3, mounting method of the present invention is simple, easy to operate.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole manual and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or ingredient, and do not get rid of other element or other ingredient.
As shown in Figure 1 to Figure 3, a kind of embodiment according to the specific embodiment of the invention is: a kind of blasting type anchor pole, it comprises the body of rod 1, rendrock 2, backing plate 5 and door 6, the hollow tubular of the body of rod 1 in upper and lower both ends open, as shown in Figure 2, the lower end edge circumference of the body of rod 1 offers several explosion grooves 10 equably, and explosion groove 10 is separated into some pieces the lower end of the body of rod 1.As shown in Figure 1, rendrock 2 is filled in the lower end of the body of rod 1 and corresponding with explosion groove 10.Be embedded with detonator 3 in rendrock 2, the payment to a porter 4 of detonator 3 extends upwardly to from the inner chamber of the body of rod 1 outside the upper end of the body of rod 1.Backing plate 5 is sheathed on the upper end of the body of rod 1.Door 5 is the T-shaped pipe of a both ends open, and the internal diameter of larger one end of door 5 is greater than the internal diameter of less one end, and less one end of door 5 is connected with the upper end of the body of rod 1, backing plate 5 is pressed in side slope 7 by larger one end.Preferably, less one end of door 6 and the upper end of the body of rod 1 are threaded connection, and less one end of door 6 is provided with external screw thread, and the upper end of the body of rod 1 is provided with corresponding internal thread, both firm and reliable connection.Further preferably, the internal diameter of larger one end of door 5 is 2 ~ 3 times of the internal diameter of the body of rod 1, thinks the thrust that backing plate 5 provides enough.
