Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.
Referring to Fig. 1 to 3, a kind of expanding enlarged footing anchor pole is empty including the body of rod 1 and the bullet shaped that 1 front end of the body of rod is arranged in
Auxocardia portion 2；The expansion section 2 is made of cylindrical part 21 and conical section 22；Described 21 one end of cylindrical part and bar
1 front end of body is fixedly connected；The conical section 22 is enclosed by muti-piece sector monolithic 221；The sector monolithic 221 and cylinder
The rotation connection of 21 other end of shape part；Sealing sliding sleeve is equipped with a bullet type pushing block 23 in the cylindrical part 21；It is described to push away
Block 23 and cylindrical part 21 enclose explosion chamber 24；Gunpowder is filled in the explosion chamber 24；The gunpowder is by extending rod
The lead 26 of 1 rear end of body is ignited；Sector 221 medial surface of monolithic is provided with protrusion 222；Described raised 222 ignite in gunpowder
Squeezing outer support by pushing block 23 afterwards makes 22 flare up claw-like of conical section；The cylindrical part 21 is by one end for connecting with the body of rod 1
To the other end, internal diameter is gradually reduced.
Further, the tip of the conical section 22 makes conical section 22 in anchor pole by spot welding or destructible external member
It is inserted into and keeps collapsing in soil course.
Further, the existence form for the gunpowder filled in the explosion chamber 24 is the gunpowder packet 25 of fire-proof and damp-proof.
Further, axially disposed in the body of rod 1 to have the through-hole being pierced by for lead 26.
Further, described raised 222 be cambered surface protrusion.
Referring to fig. 4, based on the inventive concept of the utility model, there are also different deformations for the embodiment of the utility model, such as will
Expansion section 2 is made into hollow bullet type, and inside loads gunpowder packet, and conical section 22 is gradually reduced from bottom to the thickness of tip,
And a plurality of groove mark axially extended is outputed in outer surface, after fiery charge detonation, the explosive force of generation fries conical section 22
It is split into shape of blooming, to improve the withdrawal resistance of anchor pole.
The utility model application method:
Anchor pole is hammered into soil layer, after hammering into projected depth, anchor pole is resisted with supporting element in outside, is ignited by lead 26
Gunpowder packet 25, the explosion of gunpowder packet 25 generate bulk gas, pushing block 23 are pushed to slide to conical section 22, and pushing block 23 passes through protrusion
222 strut sector 221 into claw-like, to prop up soil layer inside soil layer, the withdrawal resistance of anchor pole are improved, in this process
In, since cylindrical part 21 is from the one end connecting with the body of rod 1 to the other end, internal diameter is gradually reduced, and therefore, pushing block 23 is in movement
Make the front end deformation of cylindrical part 21 is outer to support and step up pushing block 23 in the process, so that the subsequent return of anti-thrust block 23, makes sector
Blade 221 keeps softened state.
