Specific embodiment
The cementitious composite pipe with liner is made of the cement layer 2 and inner plastic 3 for being enclosed with keel 1 (referring to specification
Attached drawing 1).
Keel 1 be made of spacer bar 8 and shaping ring 9 be evenly equipped on shaping ring 9 (referring to Figure of description 5,6 and 7) it is more
A spliced eye 10；Multiple spacer bars 8 are fitted with by 10 activity of spliced eye on multiple shaping rings 9 of interval shape setting；It is each fixed
The upper surface of type ring 9 is welded with distance bar 11；Each distance bar contradicts with the shaping ring above it connect respectively；Positioned at topmost and
The lowermost shaping ring 9 is welded to connect with spacer bar 8 respectively.
Shaping ring 9 after processing is completed can directly over end face weld distance bar 11(referring to Figure of description 7)；When assembly
After spacer bar 8 is plugged on each shaping ring 9, each shaping ring 9 is compressed；Keep each shaping ring 9 mutual by distance bar 11
It separates；Then the shaping ring 9 for being located at both ends is welded together with spacer bar 8.It can so be added by machine due to shaping ring 9
Mode batch is processed；It when assembling based on it to keel 1, can guarantee the consistency of each keel 1, avoid existing
The problem of high rejection rate having when having keel using binding reinforcing bars or welding.And it only needs when the keel 1 assembly to both ends
Shaping ring 9, which is welded, can make each spacer bar 8 be plugged into one entirety being fixed to each other of each formation of shaping ring 9, so i.e.
The welding capacity of existing keel can be greatly reduced, to improve work efficiency and the working time, existing pipe of cement is solved and have
Keel high rejection rate and Production Time long problem.
Cement layer 2 is internally provided with inner plastic 3；Inner plastic 3 has good corrosion resistance；And in plastics
The inner surface of layer 3 has the smooth characteristic in surface；Therefore it is carried out in drainage procedure using it, the impurity in water flow will be attached because lacking
Point and its surface cannot be rested on, and then avoid and lead to the problem of impurity inside existing pipe of cement and adhere to.
The inside of inner plastic 3 is evenly equipped with multiple reinforcement steel wires 6；The purpose for reinforcing steel wire 6 is arranged to be: in reinforced plastics
The intensity of layer 3.Molding keel 1 are placed in mold by the multiple tube first in production, the inner plastic that then will be made
3 penetrate into mould inside, and regulate the spacing between inner plastic 3 and keel 1；Finally by concreting in inner plastic
3 and keel 1 on, make inner plastic 3 and keel 1 be fixed to each other to form multiple tube by concrete.
Multiple connecting grooves 7 are evenly equipped on the periphery of inner plastic 3；The cross section of connecting groove 7 is in " trapezoidal "；Inner plastic
3 are embedded in connection by connecting groove 7 and cement layer 2.The purpose that connecting groove 7 is arranged is: due to cement layer 2 and inner plastic 3
The coefficient of expansion is different；If the outer surface of inner plastic 3 is in smooth state, easily generates and split between cement layer 2 and inner plastic 3
Seam, so as to cause the generation of cement layer 2 and 3 separation problem of inner plastic；When the application is embedded in by connecting groove 7 and cement layer 2,
So that cement layer 2 is extended to the inside of connecting groove 7, so that the contraction for cement layer provides certain cushion space, and then reduces
The risk that inner plastic 3 falls off.
One end of cement layer 2 is provided with grafting collar extension 4；The thickness of the other end port of cement layer 2 is greater than other parts
Thickness；The other end of cement layer 2, which is internally provided with, accepts socket 5；The outer diameter of grafting collar extension 4 is less than the internal diameter for accepting socket 5；Such as
When this can make to be assembled between the multiple tube；The grafting collar extension 4 of a piece multiple tube can smoothly be inserted into another again
In the undertaking socket 5 for closing pipe.
One end of inner plastic 3 extends to the outer end of cement layer 2；The other end end of inner plastic 3, which is located at, accepts socket 5
Inside；3 one end of inner plastic extends between the length of 2 outer end of cement layer and 3 other end of inner plastic and undertaking socket 5
Length is consistent.The purpose that inner plastic 3 is arranged such is: when the multiple tube construction and installation；Multiple tube is extended into cement
Cement is filled in the outer surface of the outer end of layer 2 and grafting collar extension 4, is then inserted into the inside of another multiple tube；To make
Shape between the undertaking socket 5 of 2 inner surface of cement layer and grafting collar extension 4 and another multiple tube of inner plastic 3 and another multiple tube
At sealing, to enhance its leakproofness；Reduce the risk of existing pipe of cement leakage.
The cementitious composite pipe structure with liner is simple, and solving the keel production that pipe of cement has, time-consuming, rejection rate
High and not corrosion-resistant problem meets the needs of enterprise's production and application.
