DETAILED DESCRIPTION

[0021] In order to make the technical scheme of the present application clearer, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0022] Embodiment 1

[0023] As Figures 1-4As shown, a kind of lining pipe for pipeline lining repair, including the pipe body 1 being provided with convex ring 2 and concave ring 3, the inner wall of convex ring 2 port is provided with convex slope 21, and the one end of concave ring 3 is provided with main slope 31 for butt joint with convex slope 21, and the other end is provided with auxiliary slope 32 for the end of pipe body 1.

[0024] Specifically, the pipe body 1 is specifically a PE lining pipe body, and the convex ring 2 and the concave ring 3 thereon are used for mutually inserting and fitting a plurality of lining pipes, and the convex ring 2 is a tubular PE material, so that the whole is of the same material during assembly with the concave ring 3.

[0025] Further, the inclination angles of the convex slope 21 and the main slope 31 are both towards the inner wall of the old pipeline, and the inclination angle of the auxiliary slope 32 is symmetrically arranged with the convex slope 21, that is, the two are two legs of an isosceles triangle.

[0026] Further, when assembling adjacent pipe bodies 1, the convex ring 2 is embedded in the concave ring 3 and is clamped, and the end of the auxiliary slope 32 abuts against the end of the pipe body 1 provided with the convex ring 2, for filling the gap between the convex ring 2 and the old pipeline, and the convex slope 21 abutting against the main slope 31 seals the adjacent pipe bodies 1, to realize the overall sealing effect of the combined arrangement of the pipe bodies 1.

[0027] When the convex ring 2 at the end of the pipe body 1 is used as a water flow impact position, the convex slope 21 is used to guide the water flow, to reduce the penetration of the water flow into the gap between the pipe body 1 and the old pipeline, and similarly, when the concave ring 3 impacts the water flow, the auxiliary slope 32 guides the water flow, and the main slope 31 guides the water flow penetrating into the pipe body 1, to reduce the generation of deviation caused by the direct impact of the water flow on the pipe body 1, and also to reduce the gap caused by the excessive impact of the water flow on the two ends of the pipe body 1, to greatly reduce the problem of the penetration of dirt into the gap between the lining pipe and the old pipeline, and to ensure the stability and sealing safety of the lining pipe during use.

[0028] As another embodiment of the utility model, a plurality of inverted protrusions 22 are equidistantly arranged on the outer side wall of the convex ring 2, and a plurality of butt joint inverted holes 33 are arranged on the inner wall of the concave ring 3.

[0029] Specifically, the inverted protrusions 22 are annularly fixed on the convex ring 2, and the inverted protrusions 22 are in the form of barbs during assembly and embedding with the butt joint inverted holes 33, and the two can be tightly connected and fixed.

[0030] The inverted protrusions 22 and the butt joint inverted holes 33 are mutually hooked and embedded and assembled, so that they are fixed after being connected and are not easy to be separated, thereby increasing the fastening effect of the connected lining pipes, and the overall resistance is larger, and the deviation problem caused by the impact of the water flow is smaller.

[0031] As another embodiment of the utility model provides, the main recess 23 is arranged on the inverted protrusion 22, and the vice recess 34 is arranged between the adjacent butt joint inverted holes 33.

[0032] Specifically, the main recess 23 can be communicated with the annular groove between the adjacent inverted protrusions 22, and the vice recess 34 can also have the same effect.

[0033] By arranging the main recess 23 and the vice recess 34 in a staggered manner, and injecting glue during the connection of the adjacent pipe bodies 1, the glue in the main recess 23 can be distributed in the annular groove between the adjacent inverted protrusions 22, and the staggered vice recess 34 can be used to distribute the glue received on the convex ring 2 in the concave ring 3, so that the glue fills the butt joint inverted hole 33, thereby improving the connection and anti-disengagement effect between the adjacent pipe bodies 1, and increasing the assembly and fastening.

[0034] As another embodiment of the utility model provides, the drainage port 24 is arranged on the outer wall of the convex ring 2 and communicated with the main recess 23.

[0035] Specifically, the drainage port 24 is located on the back of the convex slope 21, so that when the convex slope 21 is used to guide the water flow, the plurality of inverted protrusions 22 can be used to pick up the dirt, and the dirt accumulated between the adjacent inverted protrusions 22 can be used to block the gap between the pipe body 1 and the old pipeline, thereby improving the connection and sealing effect.

[0036] Further, the arc length of the drainage port 24 is greater than the arc length of the main recess 23, which aims to increase the glue supplementing and dispersing effect.

[0037] By arranging the drainage port 24, the amount of glue used during the supplementing process can be increased, and the capacity of the glue dispersion and flow can be guaranteed. When the amount of glue is excessive, the excess glue can also be used to provide a certain sealing between the convex slope 21 and the main slope 31, thereby improving the connection stability of the pipe body 1.

[0038] As another embodiment of the utility model provides, the inlet 4 is arranged on the main slope 31 and communicated with the drainage port 24.

[0039] Specifically, the inlet 4 is circumferentially arranged on the main slope 31, and the arc length of the inlet 4 is greater than the arc length of the drainage port 24.

[0040] By arranging the inlet 4 with a larger area, the glue injection effect can be better, and the glue injection position can be more easily found. In the actual construction process, the work staff can stay for a shorter time, and the excess glue can also be used to fill the convex slope 21 and the main slope 31, so that the sealing performance of the glue (the material is the prior art, which is not described here) used in the connection gap of the pipe body 1 is higher, and the corrosion resistance is stronger.

[0041] As another embodiment of the utility model provides, the sub recess 34 and the entrance 4 are on the same straight line and cooperate with the sub slope 32.

[0042] Specifically, the sub slope 32 and the pipe body 1 end, the convex ring 2 form the cavity of triangular section.

[0043] The sub recess 34 can directly receive the glue supplemented by the entrance 4, can make the glue spread in multiple butt inverted holes 33 quickly, shorten the glue distribution time, still can make the glue flow transport in the main recess 23 rate obtains auxiliary increase, and the sub recess 34 still can send the glue in triangular cavity in advance, for before waiting for the main recess 23 to be full, can make the glue block the gap between the convex ring 2 and the concave ring 3 (i.e. the gap is used as being connected with the inner wall of old pipeline), make the connection effect of pipe body 1 and old pipeline after combination assembly is stronger, and the stability is higher.

[0044] As another embodiment of the utility model provides, the pipe body 1 side wall is provided with the outer ring concave ring 5 opposite to the concave ring 3.

[0045] Specifically, the outer ring concave ring 5 is equidistantly arranged on the pipe body 1 side wall, and the outer ring concave ring 5 is on the same vertical section with the butt inverted hole 33.

[0046] The multiple outer ring concave rings 5 make the connection friction between the pipe body 1 and the old pipeline higher, and the broken particles falling on the old pipeline during the laying of the pipe body 1 can also fall into the outer ring concave ring 5 for storage and be used for strengthening the friction, and for improving the protection effect on the old pipeline.

[0047] As another embodiment of the utility model provides, the outer ring concave ring 5 is pressed by the butt inverted hole 33 and the port spacing of the outer ring concave ring 5 is adjustable.

[0048] Specifically, the outer ring concave ring 5 is semicircular in cross section, and the periphery of the port is elastic (since the PE material lining pipe itself has a certain elasticity, only the elasticity decreases with the increase of thickness).

[0049] After the pipe body 1 is installed inside the old pipeline, the multiple outer ring concave rings 5 are suction disc-shaped and fit on the inner wall of the pipeline, if there is a gap between the outer ring concave ring 5 and the old pipeline, the water pressure promotes the force between adjacent pipe bodies 1 during the subsequent water transport in the pipe body 1, and the force is transmitted to the butt inverted hole 33 after the inverted protrusion 22, so that the pressure of the ring is finally applied to the outer ring concave ring 5, and the arc-shaped recess in the outer ring concave ring 5 is deformed towards the inner wall of the old pipeline, thereby increasing the connection tightness between the pipe body 1 side wall around the outer ring concave ring 5 and the old pipeline.

[0050] Working principle: when the convex ring 2 at the end of the pipe body 1 is hit by water flow, the convex slope 21 is used to guide the water flow, reducing the water flow into the gap between the pipe body 1 and the old pipeline. Similarly, when the concave ring 3 hits the water flow, the secondary slope 32 guides the water flow, and the primary slope 31 guides the water flow into the pipe body 1, reducing the water flow directly impacting the pipe body 1 and causing the generation of deviation, and also reducing the gap caused by the water flow impact on both ends of the pipe body 1. The reverse convex 22 and the reverse hole 33 are mutually hooked and embedded assembly, so that they are connected and fixed and not easy to separate. The overall resistance is larger, and the deviation caused by water flow impact is smaller. The primary recess 23 and the secondary recess 34 are misaligned and set, and are used for glue injection during the connection of adjacent pipe bodies 1. The glue is distributed in the annular groove between the reverse convex 22 of the adjacent pipe body 1 from the primary recess 23, and the misaligned secondary recess 34 is used to distribute the glue received on the convex ring 2 in the concave ring 3, so that the glue fills the reverse hole 33. Thus, the solidified glue is distributed under the misalignment of the primary recess 23 and the secondary recess 34, improving the connection and anti-separation effect between the adjacent pipe bodies 1.

[0051] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as limiting the scope of the patent of the present application. It should be noted that for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
