It is single, positive effect, the advantages that being easily controlled, and this method because its low cost and Construction on Environment influence it is smaller and by joyous
Meet.
At present in slurry injection technique, the effect and efficiency that improve slip casting have with equipment such as slip casting machine, Grouting Pipe and filling adaptors
Close, connection speed and the connection effect of its Grouting Pipe and filling adaptor directly influence effect and the construction period of slip casting.Market
For upper common filling adaptor if in slip casting using larger grouting pressure, filling adaptor, water-stagnating effect is poor, and spillage easily occurs；Even
Connect longevity of service, reuse difficulty, cost is of a relatively high；Installation, uninstall process time length are again laborious.
Patent publication No. CN204459528 Chinese utility model patent discloses that " a kind of Grouting Pipe snaps connection dress
Put ".The technical solution of the utility model is：Including above connect Grouting Pipe, under connect Grouting Pipe, connect on described Grouting Pipe, under connect note
Slurry pipe both ends offer snap-fit grooves respectively, connect on described Grouting Pipe, under connect Grouting Pipe joint outer ring bag be provided with one
Layer sleeve, is provided with ball, if being coated with dried layer sealing rod band on the outside of the sleeve between the sleeve and snap-fit grooves.
Patent publication No. CN205578955 Chinese utility model patent discloses " slip casting pipe joint arrangement ".This practicality
New technical scheme is：Primary structure has slurry pipe joint, tight split nut, locking ring and interior tube sealing, the interior tube sealing to be fixed on
Starch in pipe joint, starch and slurry tube space is provided between pipe joint and interior tube sealing, the front portion for starching pipe joint is provided with the first external screw thread, slurry pipe
The rear portion of joint is provided with the second external screw thread, and the front inner wall for starching pipe joint is provided with the first inclined-plane, and tight split nut is provided with and first
The internal thread that external screw thread is engaged, the inwall of tight split nut are provided with the second inclined-plane, and locking ring is located at first inclined-plane and
In the space of two inclined-planes composition.
In above-mentioned patent, buckle connecting device can only connect specific Grouting Pipe, and the Grouting Pipe general to market is uncomfortable
With, and ball is installed in neck, easily there is the phenomenon of spillage；And joint structure is complex, production cost is higher, even
It is cumbersome when connecing with dismounting.
The content of the invention
In order to overcome the shortcomings of said apparatus, the utility model provides a kind of reusable slip casting pipe connection,
The attachment means use plug-in type connected mode, and connection work is convenient and swift, using rubber layer not only in the same of mortar leakage prevention
The frictional force of Shi Zeng great junctions, and have buffering effect when pressure is excessive, overall structure is simple, and production cost is low, repeats
Use.
Technical scheme is as follows used by the utility model solves its technical problem：
A kind of reusable slip casting pipe connection, connect from above Grouting Pipe, under connect Grouting Pipe, connecting tube, rubber layer,
Abnormity nut, retainer ring, waveform sheet rubber, geometrical clamp, screw thread composition, it is characterized in that：Rubber is installed in the abnormity nut
Glue-line and retainer ring, rubber layer are embedded in the groove that abnormity nut is reserved, and retainer ring is welded on abnormity nut, connection
Screw thread is provided with pipe, when in use, connect by Grouting Pipe and under connect Grouting Pipe and be inserted between abnormity nut and connecting tube
Space, rotate abnormity nut and promote waveform sheet rubber to deform, connect in compressing Grouting Pipe and under connect Grouting Pipe, make pre- interspace
It is closed.
Preferably, the abnormity nut is provided with the screw thread docked with connecting tube contact position, is connected through a screw thread, special-shaped spiral shell
Mother metal matter is stainless steel.
Preferably, described waveform sheet rubber one end is fixed in connecting tube by geometrical clamp, and the other end is embedded in fixation
Ring and connecting tube it is pre- interspace in.
Preferably, the space between abnormity nut and connecting tube be slightly larger than above connect Grouting Pipe and under connect the thickness of pipe of Grouting Pipe.
The beneficial effects of the utility model are：1st, installation facilitates with dismounting：Due to being connected using plug-in type, scene is only
It manually operated need to can be easily accomplished, pacify quick, laborsaving during loading, unloading, reduction construction cost.2nd, favorable working performance：In slip casting
Slip casting when machine pressure is big, injection slurry are not easy to leak, and notice that cleaning, maintenance of polishing can repeat to make after each use of slip casting pipe joint
With.3rd, it is cost-effective：The apparatus structure is simple, can save human cost to greatest extent in construction link, and can significantly carry
High workload efficiency, in the Grouting Pipe of various connected modes, zero consume and the waste without material head are accomplished, have greatly reduced total
Cost use easy to spread.
