Abstract

The utility model relates to a reinforced concrete pipe with a sealing rod for a jacking construction method, and belongs to a water pipe. The reinforced concrete pipe with the sealing rod is composed of a steel faucet (1), the sealing rod (2), a first thin steel cylinder (3), a first U-shaped connector (4), an outer-layer reinforcement cage (5), a second thin steel cylinder (6), a steel bell mouth (7), a second U-shaped connector (8), a third U-shaped connector (9), an inner-layer reinforcement cage (10) and concrete (11). The reinforced concrete pipe with the sealing rod can solve the problem of difficulty in altitude difference control on inside and outside concrete of the faucet end in the vertical pouring molding technology well, meanwhile, with the sealing rod, the problem of project risk caused by the reason that deviation rectification causes damage to the concrete on the top surface of the faucet in the jacking process, the underground water penetrates into the pipe through the steel faucet and the concrete gap so as to abrade the embedded reinforcement cage, is also solved, and thus, repair cost and manpower cost are reduced, production is facilitated, and meanwhile the quality of pipe pouring and pipe mounting with jacking construction method is guaranteed.

Description

The concrete reinforced pipe of jacking construction method with sealing rod
Technical field
The utility model relates to a kind of jacking construction method with the concrete reinforced pipe with sealing rod, belongs to a kind of aqueduct.
Background technique
At present reinforced concrete pipe for jacking construction method by adopting jacking construction method to install, need not excavate open channel, is well used under the complex engineering condition such as especially wear the river in some municipal sewerage engineerings, pass by on one's way.In its production process, tratitional technology adopts the vertical vibrating method of forming, the assembly jig concreting, but because there is the discrepancy in elevation in the inside and outside concrete of pipeline socket end, form the faulting of slab ends difficulty of construction very big, short due to this kind pipeline tube coupling, interface is many, the quality of pipe joint quality directly affects the quality of engineering.Secondly in adopting the jacking construction method installation process, pipeline will remain linear advancement, because the reasons such as soil resistance and construction error often need to be corrected the pipeline direction of propulsion, in the correction process, tend to cause the socket local pressure, cause pipeline socket end face concrete destruction to come off, underground water is by steel socket and concrete crack seepage inlet pipe body, cause the corrosion of Embedded Steel cage, pipeline configuration is destroyed, and brings potential safety hazard to engineering.
Summary of the invention
The purpose of this utility model is at the concrete reinforced pipe of a kind of jacking construction method use of design with sealing rod, solve the inside and outside concrete discrepancy in elevation of vertical casting craft socket and control that in the problem of difficulty and jacking construction process, correction causes socket end face concrete destruction, the hidden dangers in project problem that underground water causes the corrosion of Embedded Steel cage to bring by steel socket and concrete crack seepage inlet pipe body, thus construction quality guaranteed.
Jacking construction method is to realize solving socket end concrete discrepancy in elevation problem by making it dredge the separation concrete at casting process at the thin steel cylinder of joint socket two ends increase with the concrete reinforced pipe basic functional principle with sealing rod, at steel socket end and thin steel cylinder joint placement sealing rod, characteristic by sealing rod self water-swellable, solve underground water and cause the problem of Embedded Steel cage corrosion by steel socket and concrete crack seepage inlet pipe body, thereby guarantee construction quality.
jacking construction method with the concrete reinforced pipe basic structure of sealing rod by steel socket (1), sealing rod (2), thin steel cylinder one (3), U-shaped connector one (4), outer reinforcement cage (5), thin steel cylinder two (6), steel bellmouth (7), U-shaped connector two (8), U-shaped connector three (9), internal layer reinforcement cage (10), concrete (11) forms, steel socket (1) welds together with thin steel cylinder one (3) and thin steel cylinder two (6) respectively with steel bellmouth (7), sealing rod (2) sticks on steel socket (1) and thin steel cylinder one (3) weld, outer reinforcement cage (5) bottom is welded on steel bellmouth (7), the top welds together with thin steel cylinder one (3) by U-shaped connector one (4), internal layer reinforcement cage (10) is welded on respectively on thin steel cylinder two (6) and thin steel cylinder one (3) with U-shaped connector three (9) by U-shaped connector two (8), it is connected into as a whole, with concrete (11) with its parcel.
The utility model can solve vertical building in molding process preferably, the inside and outside concrete discrepancy in elevation of socket end problem rambunctious, cause socket end face concrete destruction by using sealing rod also to solve in jack-in process by correction simultaneously, the hidden dangers in project problem that underground water causes the corrosion of Embedded Steel cage to bring by steel socket and concrete crack seepage inlet pipe body, reduce repairing and cost of labor, guaranteed the quality that tubing is built and jacking construction method is installed in the time of convenient production.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.The utility model is comprised of steel socket (1), sealing rod (2), thin steel cylinder one (3), U-shaped connector one (4), outer reinforcement cage (5), thin steel cylinder two (6), steel bellmouth (7), U-shaped connector two (8), U-shaped connector three (9), internal layer reinforcement cage (10), concrete (11).
Embodiment
in actual production process, with steel cylinder coil welding machine, sheet metal is made thin steel cylinder one (3), thin steel cylinder two (6), rolled thin steel cylinder one (3), thin steel cylinder two (6) is welded on respectively on steel socket (1) and steel bellmouth (7), sealing rod (2) is bonded in the weld joint of steel socket (1) and thin steel cylinder one (3), hoop bonding one circle, to then outer reinforcement cage (5) bottom and steel bellmouth (7) be welded together, the top welds together with steel socket (1) by U-shaped connector one (4), then internal layer reinforcement cage (10) is passed through U-shaped connector two (8), U-shaped connector three (9) and thin steel cylinder two (6), thin steel cylinder one (3) links together, the interior concreting (11) of the mould of packing into, build and carry out steam curing after completing, reach the length of time, the sampling observation concrete strength, deliver to the job site after qualified.Install tubing by jacking construction method at the scene, cause the socket local pressure during correction, suffer to destroy as socket end face concrete and come off, underground water is by steel socket and concrete crack seepage inlet pipe body, at first can soak sealing rod (6), himself water-swellable, effectively shutoff gap, reach the purpose of sealing, ensure the quality of engineering.
