Specific implementation mode
It is next in the following with reference to the drawings and specific embodiments that the present invention will be described in detail.
Referring to Fig. 1 to 3, a kind of expanding enlarged footing anchor pole, including the body of rod 1 and the bullet shaped that is arranged in 1 front end of the body of rod it is empty
Auxocardia portion 2;The expansion section 2 is made of cylindrical part 21 and conical section 22;21 one end of the cylindrical part and bar
1 front end of body is fixedly connected;The conical section 22 is enclosed by polylith sector monolithic 221;The sector monolithic 221 and cylinder
21 other end rotation connection of shape part;21 interior sealing sliding sleeve of the cylindrical part is equipped with a bullet type pushing block 23;It is described to push away
Block 23 encloses explosion chamber 24 with cylindrical part 21;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 being connect 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 soil course and keeps collapsing.
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 present invention, the solution of the present invention also has different deformations, such as will be enlarged by portion 2 and do
At hollow bullet type, inside loads gunpowder packet, and conical section 22 is gradually reduced from bottom to the thickness of tip, and in outer surface
The a plurality of groove mark axially extended is outputed, after fiery charge detonation, conical section 22 is blown into shape of blooming by the explosive force of generation,
To improve the withdrawal resistance of anchor pole.
Application method of the present invention:
Anchor pole is hammered into soil layer, after hammering into projected depth, anchor pole is resisted with support 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 be slided to conical section 22, and pushing block 23 passes through protrusion
222 strut sector 221 improves the withdrawal resistance of anchor pole, in this process at claw-like to prop up soil layer inside soil layer
In, since cylindrical part 21 is from the one end being connect 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, to 23 follow-up return of anti-thrust block, makes sector
Blade 221 keeps softened state.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
