Beneficial effects of the present invention are：
1st, present slurry is under high pressure by Grouting Pipe propelling piston passage, forcing pot type piston to move downward a muscle bar A
Strut with steel plate A, until muscle bar A and main steel pipe be close to it is vertical when pot type piston stop motion, at this moment muscle bar A and steel plate A are supportted
Fixed pattern is opened for enlarged footing.Slurries start to pass sequentially through main steel pipe and enter to expand in body cavity till filling, after grout cures i.e.
A kind of standardized anchoring enlarged body can be become.Without normal direction starting shape after muscle bar A and the softened fixed patterns of steel plate A during slip casting
State is recovered, and the enlarged footing profile that muscle bar A and steel plate A is constituted is controllable, and the anchoring enlarged body anti-pulling effect after fixed pattern is good, operation letter
It is single, it is with low cost.
2nd, steel plate A of the invention and muscle bar A hinged places pass through again the domed Wa Yeshi steel plate B of hinge one, in
Muscle bar C is connected with by bearing pin on boss, the other end of muscle bar C is movably hinged by bearing pin with steel plate B, muscle bar A and muscle bar C it
Between by muscle bar B pass through hinge.Slurries start to pass sequentially through main steel pipe and enter to expand in body cavity till filling, and slurries coagulate
Gu after can become a kind of standardized taper and anchor enlarged body.The taper anchoring enlarged body is applied to clay stratum, fastness
It is higher, easy to operate, low cost.
