Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1, concrete pipe sheet Grouting Pipe, setting, pipe is connected among tube body 9 in the tube body 9 including an injection molding
The both ends of body 9 are respectively arranged with slip casting entrance and slip casting outlet, and tube body 9 includes an extension tube 1 and integrally sets with the extension tube 1
The screwed pipe set, screwed pipe include an inner tube 2, and inner tube 2 is wholely set with extension tube 1, be provided on the outer surface of inner tube 2 with it is interior
The threaded bosses 5 that pipe 2 is fixedly installed, and the diameter of threaded bosses 5 close to 1 one end of extension tube to far from 1 one end of extension tube by passing
Increase, the flight pitch 8 of threaded bosses 5 close to 1 one end of extension tube to far from 1 one end of extension tube by being incremented by.
When carrying out slip casting using this concrete pipe sheet Grouting Pipe, first check on the outer surface of tube body 9 with the presence or absence of scratch or
The defects of person abrades, it is ensured that it is secondary without then clearing up the pedestal cooperated with this Grouting Pipe on mold after defect, it is hand-held to prolong
The screwed pipe of tube body 9 is placed on the pedestal of mold Grouting Pipe by long tube 1, and ensures that the screwed pipe position of Grouting Pipe rotates to
Then position carries out slip casting by this Grouting Pipe, due to being provided with threaded bosses 5 on the outer surface of screwed pipe, when completion note
After slurry, the close combination in gap between slip casting and threaded bosses 5, enhance Grouting Pipe and slip casting holds resultant force, to effectively increase
Add Grouting Pipe extraction-resistant behavior, also improve the flat performance of extruding of its own, increases the safety of section of jurisdiction installation.
Inner tube 2 is provided with circular protrusion 3, and the excircle of circular protrusion 3 in the end outer surface far from 1 one end of extension tube
Outer surface of the surface above threaded bosses 5.The surface of circular protrusion 3 is provided with screw thread, and by the screw thread and mold
The pedestal of Grouting Pipe is adapted installation, and slip casting enters in this Grouting Pipe from Grouting Pipe on mold.
Several threads 4 are fixedly installed on the outer surface of threaded bosses 5.The external peripheral surface of thread 4 is above ring
The outer surface of shape protrusion 3.Spacing 8 between two neighboring thread 4 differs.Thread 4 is set with the integrated molding of threaded bosses 5
It sets.Thread 4, threaded bosses 5 center line be overlapped with the center line of inner tube 2, the section outer edge of thread 4 is rectangle.Edge
Holding up for tube body 9 is provided with an interconnecting piece 6 on direction, interconnecting piece 6 is fixedly installed by fixed part 7 and thread 4, passes through connection
Portion 6 and fixed part 7 may further ensure that the stability of thread 4.Since threaded bosses 5 have the edge of arc,
In some cases or there is the risks for bonding scarce capacity, cooperate the outer edge of rectangular section, and the height of thread 4
Above threaded bosses 5, screwed pipe can be further enhanced to the binding force of slip casting, thus enhance section of jurisdiction installation fastness and
Safety.
Extension tube 1 is plastic material.Inner tube 2 is plastic material.Threaded bosses 5 and thread 4 are plastic material.Using modeling
Expect material, it is such as ABS engineering plastics, extension tube 1, inner tube 2, threaded bosses 5 and thread 4 is integrated using ABS engineering plastics
Injection molding forms, and structural integrity is good, has stronger stability, meanwhile, ABS engineering plastics can be effectively prevented slip casting
It corrodes, prolongs its service life caused by it.
The working principle of the concrete pipe sheet Grouting Pipe is: being wholely set the side of threaded bosses 5 using on 2 surface of inner tube
Formula enhances the bond stress between tube body 9 and slip casting, guarantees the safety and fastness of section of jurisdiction installation；Pass through setting thread 4
Mode further promotes the binding force between tube body 9 and slip casting, improves the extraction-resistant behavior and the anti-flattening of itself of Grouting Pipe
Can, increase the fastness when installation of section of jurisdiction；Using plastic material, avoids slip casting from causing to corrode to it and cause that there are security risks
Problem；For total using setting is integrally formed, globality is strong, highly-safe.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
