Abstract
A kind of Prestressed concrete cylinder pipe, tube body one end are provided with socket, outer tooth are evenly distributed on socket, socket is embedded with steel plate on end face, the tube body other end is provided with bellmouth, and the interior tooth to match with outer tooth is distributed on bellmouth, water swelling rubber ring is provided on bellmouth.The utility model has the advantages that easy for construction, good airproof performance, solid reliable.
Description
Technical field
The utility model belongs to pipe technology field, and in particular to arrives a kind of Prestressed concrete cylinder pipe.
Background technology
Prestressed concrete cylinder pipe (abbreviation PCCP) is a kind of novel rigid pressure tubing.It is the height with steel cylinder
Strength concrete tube core winds presstressed reinforcing steel, sprays with cement mortar protective course, is steel plate, concrete, presstressed reinforcing steel, cement mortar
The composite construction of different materials composition, has steel and the respective characteristic of concrete.Prestressed concrete cylinder pipe, which has, to be born
Interior external pressure is high, construction is convenient, antiseptic property is good and the characteristics such as easy to maintain.Compared with previous tubing, have it is applied widely,
The advantages such as the economic life is long, anti-seismic performance is good, operation expenditure easy for installation is low, main application is in long distance water transfer main line, pressure
The fields such as power inverted-siphon, urban water supply engineering, pressure water conveyer line pressure blowdown main line, by engineering circles institute extensive concern.
But between each tube coupling of Prestressed concrete cylinder pipe the sealing water resistance of connector be face at present one urgently
Problem to be solved.Current most of joint forms are welded into one using steel bell and spigot and with steel cylinder, and bell and spigot band is fluted
The slidingtype cushion rubber flexible joint that sealing rubber ring is formed, such joint form directly rotate to meet tube coupling, have ignored pipe
It needs reliably to connect between section, once intermediate any section agent structure is destroyed, then may influence whole section of prestressing force
Cylinder concrete pipe tube coupling is detached from, and consequence is hardly imaginable.
Utility model content
The technical problem to be solved by the utility model is to overcome existing Prestressed concrete cylinder pipe, provide
A kind of easy for construction, good airproof performance, solid reliable Prestressed concrete cylinder pipe.
Technical solution is used by solving technical problem used by above-mentioned technical problem：Tube body one end is provided with slotting
Mouthful, it is evenly distributed with outer tooth on socket, steel plate is embedded on socket end face, the tube body other end is provided with bellmouth, divides on bellmouth
It is furnished with the interior tooth to match with outer tooth, water swelling rubber ring is provided on bellmouth.
As a kind of perferred technical scheme, the tube body is followed successively by inner concrete layer, steel cylinder, outer mixed from inside to outside
Soil layer is coagulated, presstressed reinforcing steel is wound on outer concrete layer and has poured cement mortar protective course.
As a kind of perferred technical scheme, the presstressed reinforcing steel is carbon fiber presstressed reinforcing steel.
The beneficial effects of the utility model are as follows：
The utility model is outer using being provided with interior tooth in the bellmouth of Prestressed concrete cylinder pipe, being provided with outside socket
Tooth, and in the pre-buried smooth steel plate in socket end end, ensure that water proofing property, the leakproofness of joint, also ensure that each tube coupling reliably connects
It connects, the joint of the utility model has enough strength and stiffness to resist due to being answered caused by uneven settlement of foundation
Power ensures the safe normal operation of Prestressed concrete cylinder pipe, even if a certain section in whole section of Prestressed concrete cylinder pipe
Structure is destroyed, and the discrepancy of adjacent tube coupling will not be caused to occur and jeopardize whole section of operation, it is only necessary to targetedly more
Normal operation can be restored by changing.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
With reference to the accompanying drawings and examples to the utility model be further described, but the utility model be not limited to it is following
Embodiment.
In Fig. 1, a kind of Prestressed concrete cylinder pipe of the present embodiment by tube body 2, socket 3, bellmouth 1, outer tooth 4,
Interior tooth 5, water swelling rubber ring 6, steel plate 7 connect and compose.
Tube body 2 is followed successively by inner concrete layer 2-5, steel cylinder 2-4, outer concrete layer 2-3 from inside to outside, on outer concrete layer
It is wound with carbon fiber presstressed reinforcing steel 2-2 and has poured cement mortar protective course 2-1,2 one end of tube body is machined with socket 3, socket 3
On be evenly distributed with outer tooth 4, socket is embedded with steel plate 7 on 3 end face, combines closely when being docked for socket 3 and bellmouth 1, Guan Ben
2 other end of body is machined with bellmouth 1, and the interior tooth 5 to match with outer tooth 4 is distributed on bellmouth 1, water-swellable is equipped on bellmouth 1
Rubber ring 6, tube body 2, bellmouth 1, socket 3 are linked together.
The socket of a piece Prestressed concrete cylinder pipe and the bellmouth of another Prestressed concrete cylinder pipe are attached
When, first tooth outside interior tooth is staggered, the water swelling rubber ring installed with female end is then allowed to by jack pushing tow socket end
It combines closely, the pre-buried smooth steel plate in socket end end ensures the two seamless combination, passes through rotation while the two is combined closely
Wherein a Prestressed concrete cylinder pipe is stuck by interior tooth and outer tooth, forms rigid joint, and the utility model ensure that and connect
Water proofing property at head, and may insure that each tube coupling is reliably connected, the utility model guarantee joint is with enough intensity and just
It spends to resist due to stress caused by uneven settlement of foundation, ensures the safe normal operation of Prestressed concrete cylinder pipe,
Even if a certain section structure in whole section of Prestressed concrete cylinder pipe is destroyed, the disconnection of adjacent tube coupling will not be caused existing
Jeopardize whole section of operation as generation, it is only necessary to which normal operation can be restored by targetedly replacing.
