Detailed Description
The utility model aims to overcome prior art's defect, provide novel glass steel inside lining concrete composite tube, it is right to combine the embodiment below the utility model discloses do further detailed description.
Examples
As shown in fig. 1, the novel glass fiber reinforced plastic lined concrete composite pipe comprises a glass fiber reinforced plastic lining layer 1, an elastic interface layer 2, a functional layer 3 and a concrete layer 4 which are sequentially arranged from inside to outside.
The elastic interface layer 2 is made of a material having elasticity and a large friction coefficient, such as resin. The friction force of the elastic interface layer 2 is large, and the glass fiber reinforced plastic lining layer 1, the functional layer 3 and the concrete layer 4 are prevented from displacing.
Furthermore, one end of the glass fiber reinforced plastic lining pipe is provided with a socket 5, the other end of the glass fiber reinforced plastic lining pipe is provided with a socket 6, and the socket 5 is provided with a groove mounting sealing ring 7. The connection of the two combined pipes is realized by a traditional plug-in mode, and the embodiment is not described in detail due to the prior art.
It is worth emphasizing that, in the core technical solution of the present embodiment, the structure of the functional layer 3.
In this embodiment, the functional layer 3 comprises an annular hollow cylinder of steel material. A spiral tube 8 which is coaxial with the annular cylinder is arranged in the annular cylinder, and one end of the spiral tube 8 is the end of the splicing end 9 which extends out of the annular hollow cylinder. The other end of the spiral pipe 8 is the other end of the bearing end 10 extending out of the annular hollow cylinder. The outer wall of the bearing end 10 of the spiral pipe 8 is provided with an annular groove which is provided with a sealing ring 7. When the two combined pipes are connected, the spiral pipes 8 of the two combined pipes are also connected in an inserting mode, and the inserting mode is completely the same as that of the glass fiber reinforced plastic. It is worth emphasizing that the spiral pipe 8 is welded and sealed at the position extending out of the annular cylinder body so as to ensure that the interior of the annular cylinder body is sealed. The sizes of the inserting end 9 and the bearing end 10 are such that the joint of the two combined pipes is completely attached after the two combined pipes are inserted.
And a plurality of second annular reinforcing ribs 12 are arranged between the spiral pipe 8 and the inner wall of the annular hollow cylinder body to support the spiral pipe 8. A first annular reinforcing rib 11 is arranged between two corresponding inner walls of the annular hollow cylinder body.
Thus, the functional layer 3 can achieve the effect that, when the composite pipe is connected, two lines are actually formed, one being a fluid line and the other being a medium pipe in a spiral shape; the medium pipe can be filled with medium for heating or cooling. Such as hot oil, cold oil, hot water, cold water. Through the structure, different media are introduced according to heating or heat dissipation requirements, so that the heating or heat dissipation effect is realized.
Simultaneously, it is weaker with concrete layer 4's radial cohesion to solve glass steel, and when intraductal pressure was great, the glass steel layer will produce outside bulging force, and this bulging force directly acts on outer wall concrete layer 4, and concrete layer 4 will bear very big pulling force this moment, and concrete layer 4 will take place to rise to become garrulous and make the cracked problem of pipeline. Firstly, the elastic interface layer 2 increases the radial binding force between the glass fiber reinforced plastic lining and the functional layer 3 and the concrete layer 4 due to large friction force, and the elastic interface layer 2 has elasticity and deformation capacity, so that the transmitted pressure is reduced, and the elastic interface layer cannot expand but deform due to the deformation capacity of the elastic interface layer, so that the probability of top crack of concrete is reduced. And the functional layer 3 is structured to be provided with a second annular reinforcing bead 12 and a first annular reinforcing bead 11. The reinforcing ribs are annular, so that the functional layer 3 also has certain deformation capacity, when the internal pressure is higher, the functional layer 3 elastically deforms, the transmitted pressure is reduced, the deformation is realized, the generated expansion is small, and the probability of bursting the concrete layer 4 is reduced.
And because the functional layer 3 is made of steel material, even if the concrete layer 4 is cracked, the functional layer 3 has certain protection effects of impact resistance and external force resistance because the structure of the functional layer 3 has deformation resistance, and therefore, even if the concrete layer 4 is cracked due to various reasons, the combined pipe can be used for a long time to a certain extent. In this embodiment, the spiral tube 8 is incorporated in the functional layer 3, and provides a medium for heating and cooling, and is a circular tube, and also functions as a reinforcing rib having deformability.
The outermost concrete is provided with reinforcing steel bars for reinforcement, and the concrete is poured on the functional layer 3 for forming. Two corresponding guide insertion blocks 13 are arranged at one end of the concrete layer 4, and two corresponding guide insertion grooves 14 are arranged at the other end of the concrete layer 4. The length of the guide insert 13 is greater than the length of the socket 6 to guide the insertion of the socket 6.
According to the above embodiment, alright realize the utility model discloses well. It is worth to say that, on the premise of the above structural design, in order to solve the same technical problem, even if some insubstantial changes or retouching are made in the utility model, the essence of the adopted technical scheme is still the same as the utility model, so it should be in the protection scope of the utility model.
