Description

Technical Field

[0001] The utility model relates to a continuously wound glass fiber reinforced plastic liner, in particular to a continuously wound glass fiber reinforced plastic liner with a positioning structure. Background Art

[0002] With the development of urban construction, a large number of urban underground pipelines have been put into construction, which has brought convenience to people's lives. However, most of the pipes in the existing technology are made of concrete, PVC-PE materials, ductile iron and other materials. The ductile iron pipe has a complex production process and high production cost. In addition, due to its heavy weight, it is not convenient for transportation and on-site construction. Concrete, PVC and PE pipes are prone to aging due to long service life and are not pressure-resistant.

[0003] After several years of laying, concrete, PVC-PE, ductile iron and other pipelines may be damaged or leak due to ground subsidence, pressure from large-tonnage trucks and other conditions. In most cases, it is necessary to excavate the ground and repair or replace the damaged pipelines. If a long damaged pipeline needs to be excavated and replaced as a whole, the cost will be very high. If there are buildings above the pipeline, construction cannot be carried out, and the pipeline needs to be diverted, etc., the project will be very expensive.

[0004] In the prior art, a liner is usually inserted into a damaged pipe for repair. If a long-length pipe is damaged, multiple liners need to be inserted into the damaged pipe. However, when inserting multiple pipes, the specific situation of the pipe insertion cannot be seen. During the insertion, the ports of the two pipes often collide due to excessive force, resulting in damage to the pipe ports and the risk of leakage. Therefore, a continuously wound glass fiber reinforced plastic liner with a positioning structure is proposed. Utility Model Content

[0005] The utility model aims to solve the above problems and provides a continuously wound glass fiber reinforced plastic liner with a positioning structure.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a continuously wound glass fiber reinforced plastic liner with a positioning structure, comprising a liner body, wherein the liner body comprises an inner lining layer, a structural layer and an outer layer; it is characterized in that it also comprises positioning structures arranged at both ends of the liner body for connecting and positioning adjacent liner bodies, the positioning structure comprises a receiving end arranged at one end of the liner body and an insertion end arranged at the other side of the liner body; the receiving end is provided with a socket sleeve inserted into the liner body and matched with the liner body, and the insertion end is provided with a connecting sleeve matched with the socket sleeve and used for inserting into the socket sleeve.

[0007] Further preferably, the port of the connecting sleeve and the port of the socket sleeve are both provided with guide surfaces for guiding purposes.

[0008] Further preferably, sealing buffer pads are installed on the end surfaces of the receiving end and the inserting end, and the surface of the sealing buffer pads is provided with a plurality of teeth.

[0009] Further preferably, the teeth are arranged in an inclined shape, and the teeth on the receiving end sealing buffer pad and the teeth on the inserting end sealing buffer pad are arranged in opposite inclination directions.

[0010] Further preferably, the connecting sleeve and the socket sleeve are provided with semi-sealing grooves corresponding in position, and the semi-sealing groove on the connecting sleeve is aligned with the semi-sealing groove on the socket sleeve to form a complete sealing groove.

[0011] Further preferably, a sealing ring is installed in the sealing groove.

[0012] The beneficial effects of the utility model are as follows: through the setting of the positioning structure, the connection position between adjacent liner bodies is limited and positioned, and at the same time, it also plays a guiding role when the liner bodies are connected, thereby improving the accuracy of the connection position between adjacent liner bodies and avoiding leakage problems at the connection due to port position deviation;

[0013] By installing sealing buffer pads on the end faces of the socket end and the insertion end, they play an elastic buffering role when contacting the end face of another liner body during the jacking process of the liner body, and play a sealing role after the early connection, so as to avoid the end faces of the two liner bodies colliding during the jacking and causing port damage, thereby affecting the connection and sealing between adjacent liner bodies;

[0014] By arranging a plurality of teeth on the surface of the sealing buffer pad, and the teeth on the socket end and the insertion end are arranged oppositely, the teeth are driven to deform by the extrusion force after the sealing buffer pads on both sides come into contact. The opposite arrangement can form a multi-stage seal through the teeth on both sides, thereby further increasing the sealing performance. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] See also Figure 1-6 As shown in, a continuously wound glass fiber reinforced plastic liner with a positioning structure comprises a liner body 1, wherein the liner body 1 comprises an inner lining layer 11, a structural layer 12 and an outer surface layer 13; it is characterized in that it also comprises positioning structures arranged at both ends of the liner body 1 for connecting and positioning adjacent liner bodies 1, wherein the positioning structure comprises a receiving end 2 pasted on one end of the liner body 1 and an inserting end 3 pasted on the other side of the liner body 1; the receiving end 2 is provided with a socket sleeve 21 inserted into the liner body 1 and matched with the liner body 1, and the inserting end 3 is provided with a connecting sleeve 31 matched with the socket sleeve 21 and used for inserting into the socket sleeve 21;

[0026] By setting the positioning structure, the connection position between adjacent liner bodies 1 is limited and positioned, and it also plays a guiding role when the liner bodies 1 are connected, thereby improving the accuracy of the connection position between adjacent liner bodies 1 and avoiding leakage problems at the connection due to port position deviation.

[0027] In one embodiment, the port of the connecting sleeve 31 is provided with a guide surface 32 for guiding. The setting of the guide surface 32 guides the insertion of the connecting sleeve 31 into the receiving sleeve, thereby facilitating the connection and cooperation between the connecting sleeve 31 and the receiving sleeve and avoiding interference caused by deviation of the end face position.

[0028] In one embodiment, a sealing buffer pad 4 is installed on the end surfaces of the receiving end 2 and the inserting end 3, and a plurality of teeth 41 are arranged on the surface of the sealing buffer pad 4;

[0029] By installing a sealing buffer pad 4 on the end faces of the socket end and the insertion end 3, it plays an elastic buffering role when contacting the end face of another liner body 1 during the jacking process of the liner body 1, and plays a sealing role after the early connection, thereby avoiding the end faces of the two liner bodies 1 colliding during the jacking and causing port damage, thereby affecting the connection and sealing between adjacent liner bodies 1.

[0030] In one embodiment, the teeth 41 are arranged in an inclined shape, and the teeth 41 on the sealing buffer pad 4 at the receiving end 2 and the teeth 41 on the sealing buffer pad 4 at the insertion end 3 are arranged in opposite directions;

[0031] A plurality of teeth 41 are arranged on the surface of the sealing buffer 4, and the teeth 41 on the socket end and the insertion end 3 are arranged oppositely, so that after the sealing buffers 4 on both sides come into contact, the teeth 41 are driven to deform by the extrusion force, and the opposite arrangement can form a multi-stage seal through the teeth 41 on both sides, thereby further improving the sealing performance;

[0032] Furthermore, since the teeth 41 on both sides are arranged with opposite inclination directions, the teeth 41 on both sides may be plugged into each other during extrusion fitting, and the sealing performance of the connection can be further improved after plugging into each other.

[0033] In one embodiment, the connecting sleeve 31 and the socket sleeve 21 are provided with semi-sealing grooves 5 corresponding to each other, and the semi-sealing groove 5 on the connecting sleeve 31 is aligned with the semi-sealing groove 5 on the socket sleeve 21 to form a complete sealing groove; a sealing ring 6 is installed in the sealing groove;

[0034] By setting the semi-sealing groove 5, the sealing ring 6 is installed on the sealing groove of the connecting sleeve 31 before installation. When the connecting sleeve 31 is inserted into the socket sleeve 21, the inner wall of the socket sleeve 21 squeezes the sealing ring 6 until the connecting sleeve 31 is plugged into place. The semi-sealing groove 5 on the connecting sleeve 31 is aligned with the semi-sealing groove 5 on the socket sleeve 21 to form a complete sealing groove. At this time, the sealing ring 6 is stuck in the sealing groove, which seals the connecting sleeve 31 and the socket sleeve 21 and limits the axial position, thereby preventing axial movement from occurring easily and causing separation between adjacent liner bodies 1.

[0035] When the utility model is in use: first, the first liner body 1 is pushed and installed into the damaged pipe body, and then the second liner is pushed into the damaged pipe. During the pushing process, when the connecting sleeve 31 on the pushed liner body 1 contacts the receiving sleeve on the previous liner body 1, the connecting sleeve 31 contacts the port of the receiving sleeve through the guide surface 32, and is inserted into the receiving sleeve along the guide surface 32 during the continuous pushing process. During the insertion process, when the sealing ring 6 contacts the receiving sleeve, it is squeezed by the inner wall of the receiving sleeve and deformed, until the sealing buffer pad 4 on the socket end and the insertion end 3 contacts, the subsequent liner body cannot be pushed in, and the connection between the previous liner body and the subsequent liner body is completed. At this time, the sealing groove on the connecting sleeve 31 is aligned with the sealing groove on the socket sleeve 21, and the sealing ring 6 is stuck in the complete sealing groove, which plays a sealing role and limits the axial movement of the two liner bodies 1 at the same time, to prevent axial movement from causing the connection between the two pipe bodies to be disconnected.

[0036] The protection scope of the present utility model is not limited to the above embodiments and their variations. Conventional modifications and replacements made by those skilled in the art based on the contents of this embodiment all fall within the protection scope of the present utility model.
