[0025] like Figures 1 to 4As shown, a leakproof reinforced concrete drainage pipe comprises a pipe body 1, wherein the left and right ends of the pipe body 1 are respectively installed with a cast-in-one left docking ring 2 and a right docking ring 3, a sealing ring 4 is fixedly installed on the inner wall surface of the left docking ring 2, a plurality of "L"-shaped plug-in grooves 5 are opened on the inner wall surface of the sealing ring 4, and an "L"-shaped plug-in block 6 is plugged into the interior of each plug-in groove 5, a fixing ring 9 is installed at the other end of the plurality of plug-in blocks 6, and the other end of the fixing ring 9 is fixedly connected to the inner wall surface of the right docking ring 3, an external connecting portion 7 for fixing the right docking ring 3 is provided on the left docking ring 2, and an external sealing portion 8 for sealing the outer side of the connection between the plug-in groove 5 and the plug-in block 6 is provided on the adjacent side of the left docking ring 2 and the right docking ring 3;

[0026] In order to ensure that the stress points at the connection between the left docking ring 2 and the right docking ring 3 are uniform, the plurality of said plug-in slots 5 and the plurality of said plug-in blocks 6 are distributed in a circular pattern;

[0027] Specifically, by inserting multiple plug-in blocks 6 into the inside of the plug-in groove 5 one by one, and then casting the fixing ring 9 to be connected to the other end of the multiple plug-in blocks 6, the movable connection of the left docking ring 2 and the right docking ring 3 can be achieved, and the outer side of the docking point of the plug-in groove 5 and the plug-in block 6 can be sealed by the provided external sealing portion 8, and the stability and sealing of the connection between the left docking ring 2 and the right docking ring 3 can also be enhanced, and the internal leakage of the docking point of the left docking ring 2 and the right docking ring 3 can be effectively prevented, thereby improving the leakage-proof effect at the interface of the two pipe bodies 1. The external connecting portion 7 can enhance the firmness and stability of the connection between the two pipe bodies 1. At the same time, with the assistance of the "L"-shaped plug-in groove 5 and the plug-in block 6, when the docking point of the two pipe bodies 1 loosens and moves away from each other, the connection stability of the docking point of the two pipe bodies 1 can be guaranteed under the mutual pulling action of the plug-in groove 5 and the plug-in block 6, and the loosening of the interface of the two pipe bodies 1 can be avoided to cause water leakage.

[0028] The inner wall surface of the plug-in slot 5 and the outer wall surface of the plug-in block 6 are both bonded with sealing rubber pads;

[0029] Specifically, the sealing rubber pad can enhance the tightness of the connection between the plug slot 5 and the plug block 6, improve the sealing effect between the plug slot 5 and the plug block 6, and avoid leakage at the connection between the plug slot 5 and the plug block 6.

[0030] like Figure 1 and Figure 2 As shown, the external connection part 7 includes a threaded hole 1 701 and a threaded hole 2 702, and the left docking ring 2 and the right docking ring 3 are each provided with three circumferentially distributed threaded holes 1 701 and threaded holes 2 702, and a fastening screw 703 is threadedly connected between the corresponding threaded holes 1 701 and threaded holes 2 702 on the left and right;

[0031] Specifically, by passing the fastening screw 703 through the threaded hole 1 701 and the threaded hole 2 702 from left to right in sequence, the connection and fixation of the left docking ring 2 and the right docking ring 3 can be achieved, thereby enhancing the relative stability between the two pipe bodies 1 when the other end of the plug-in block 6 is cast on the fixing ring 9, avoiding the shaking and displacement of the relative positions of the two pipe bodies 1 when the plug-in block 6 and the fixing ring 9 undergo cement hydration reaction, and ensuring the quality and effect of fixing the plug-in block 6 to one end of the fixing ring 9.

[0032] like Figure 1 As shown, the outer sealing portion 8 includes a second sealing block 802, a second sealing block 802 in a concave shape is fixedly connected to the side wall surface of the left docking ring 2, and a second sealing block 802 in a convex shape is fixedly connected to the side wall surface of the right docking ring 3, and the first sealing block 801 and the second sealing block 802 are plugged into each other;

[0033] Specifically, by connecting one end of the plug-in block 6 to a side wall of the fixing ring 9, the two tube bodies 1 are brought closer to each other. At this time, the sealing block 802 can be horizontally moved to one side of the left docking ring 2 until the protruding end of the sealing block 801 can be plugged into the inside of the sealing block 802, thereby achieving the purpose of sealing the outside of the docking point between the plug-in groove 5 and the plug-in block 6. At the same time, it can also enhance the firmness and stability of the connection between the left docking ring 2 and the right docking ring 3, prevent leakage from occurring inside the docking point, and improve the sealing and leak-proof effect of the docking point of the two tube bodies 1.

[0034] like Figure 1 As shown, the inner wall surface of the sealing block 1 801 is connected with a magnetic sheet 804, and the outer wall surface of the sealing block 2 802 is connected with an iron sheet 803, and the iron sheet 803 and the magnetic sheet 804 are attracted to each other;

[0035] Specifically, the iron sheet 803 and the magnetic sheet 804 attract each other, so that the firmness of the connection between the sealing block 1 801 and the sealing block 2 802 can be enhanced when the sealing block 1 801 is inserted into the sealing block 2 802 .

[0036] like Figure 4 As shown, the wall surfaces of the left docking ring 2 and the right docking ring 3 that are away from each other are fixedly connected with an inclined receiving slope 10 and a receiving slope 2 11, and the other ends of the receiving slope 10 and the receiving slope 2 11 abut against the inner wall surface of the pipe body 1;

[0037] Specifically, by setting the receiving slope 10 and the receiving slope 2 11, a slope can be formed between the sealing ring 4 (fixing ring 9) and the inner wall of the pipe body 1, thereby reducing the impact force of the water flow of the pipe body 1 rushing to the sealing ring 4 and the fixing ring 9 when draining water, and effectively reducing the damage of the water flow to the sealing ring 4 and the fixing ring 9 during drainage. At the same time, it can also avoid the formation of a height difference between the ends of the sealing ring 4 and the fixing ring 9 that are far away from each other and the inner wall of the pipe body 1, thereby preventing some impurities and garbage from being blocked at the height difference during underground drainage.

[0038] In summary: by inserting a plurality of plug-in blocks 6 into the inside of the plug-in groove 5 one by one, and then casting and connecting the fixing ring 9 to the other end of the plurality of plug-in blocks 6, the movable connection of the left docking ring 2 and the right docking ring 3 can be realized, and the outer sealing portion 8 provided can seal the outer side of the docking place between the plug-in groove 5 and the plug-in block 6, and at the same time, the stability and sealing of the connection between the left docking ring 2 and the right docking ring 3 can be enhanced, effectively preventing leakage from occurring inside the docking place between the left docking ring 2 and the right docking ring 3, and improving the anti-leakage effect at the interface of the two pipe bodies 1;

[0039] The external connection part 7 can enhance the firmness and stability of the connection between the two tube bodies 1. At the same time, with the assistance of the "L"-shaped plug-in groove 5 and the plug-in block 6, when the two tube bodies 1 become loose at the joint and move away from each other, the plug-in groove 5 and the plug-in block 6 can pull each other to ensure the connection stability of the two tube bodies 1 at the joint, thereby avoiding water leakage caused by looseness at the interface of the two tube bodies 1.
