Hole；Corresponding, the shim through bore for closing gasket 104 is identical as the special-shaped hole shape of stop grouting plug 102.
In the embodiment of the present invention, stop grouting plug 102 is rubber material, gland 2, pedestal 101, closing gasket 104, return pipe
103 be steel.
The working principle of the embodiment of the present invention are as follows: drilling machine kelly connects Grout-jetting pipe, and drilling machine kelly can pass through pressure
Lid 2 and sealer 1,1 lower section of sealer reserve overfall mouth and connect return pipe 103 to carry out overfall, place one in sealer 1
The irregularly-shaped hole that is drilled with identical as 101 internal diameter of pedestal, intermediate places two for the rubber stopper that drilling machine kelly passes through again on it
Block closes gasket 104, two pieces of closing gaskets 104 of lower placement, and two pieces of closing gaskets 104 are welded to connect；Drilling machine kelly is worn
It crosses irregularly-shaped hole to connect with Grout-jetting pipe, gland 2 squeezes the stop grouting plug of closing backing plate and rubber material by screwed connection pedestal 101
102, so that stop grouting plug 102 is compressed drilling machine kelly after by compression swelling, play the role of sealing or only slurry, pedestal 101 passes through screw thread
It is connect with drill hole pipe and plays fixed function；During slip casting can freely up and down Grout-jetting pipe, meanwhile, drilling machine actively
The problems such as drilling rod can also rotate together with stop grouting plug 102, avoid pipe laying caused by grout cures.
The application method of the embodiment of the present invention are as follows: choose the sealer that its stop grouting plug 102 is matched with drilling machine kelly
1, before slip casting, gland 2 and sealer 1 are connected, screw thread (screw thread) micro- pine, then by 1 bottom end of sealer and orifice tube
Tight firm, designated position in underlying Grout-jetting pipe to hole, mobile drill makes kelly be connected with Grout-jetting pipe, and protrudes into locking device
It is interior, gland 2 is finally screwed, squeezing stop grouting plug 102 compresses it with drilling machine kelly, realizes closing sealing and only starches, is returning
Slurry mouth, which loads onto valve and return pipe 103, can carry out slip casting operation, easy to operate, within installation process 15 minutes；In slip casting
Cheng Zhong can drive Grout-jetting pipe freely up and down movable in the complete tripping in hole of drilling machine kelly, when necessary can also fine rotation.
Advantages of the present invention are as follows:
1) it is provided with the stop grouting plug 102 of rubber material in sealer 1, avoids the underlying stop grouting plug 102 in hole, prevents burying thing
Therefore generation, reduce accident risk；
2) it is easy to use rigid material to do Grout-jetting pipe, recycling can save material, and carry using the hoisting power of drilling machine
Or fine rotation Grout-jetting pipe, reduce slip casting holding tube probability under high pressure；
3) during slip casting special-shaped kelly can pass freely through orifice closing device in injected hole up and down, slow-speed of revolution rotation lives
It is dynamic, it does not influence only to starch effect, mortar depositing construction is interrupted without interim, ensure that the continuity of slip casting；Slip casting effect is effectively guaranteed
Rate and quality；
4) present invention remove rubber material stop grouting plug 102, other component is steel, bear pressure it is higher, up to 15MPa with
On；102 upper and lower ends of stop grouting plug are equipped with the phenomenon that closing backing plate ensure that closure, bad sealing is not present；
5) stop grouting plug 102 in the present invention has different size, is selected according to the shape of drilling rod, mating with drilling rod shape；It is small by six
Side, big six side, two side's kellies can use, and have specific aim and comprehensive.
The above content is specific embodiment is combined, further detailed description of the invention, and it cannot be said that this hair
Bright specific implementation is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, it is not taking off
Under the premise of from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to protection of the invention
Range.
