Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Examples:

referring to fig. 1-4, a reinforced concrete drain pipe convenient for butt joint comprises a first pipeline 1 and a second pipeline 2, wherein the right sides of the first pipeline 1 and the second pipeline 2 are fixedly connected with a connecting ring 3, the left sides of the first pipeline 1 and the second pipeline 2 are fixedly connected with a butt joint ring 4, a butt joint groove 401 is formed in the middle position of each butt joint ring 4, a plurality of limit grooves 5 are formed in the inner wall of the outer ring of each butt joint groove 401, a plurality of avoidance grooves 6 are formed in the outer surface of each connecting ring 3, the upper ends of the right sides of the avoidance grooves 6 are hinged with limiting blocks 7, springs 8 are fixedly connected to the left sides of the bottom ends of the avoidance grooves 6, the other ends of the springs 8 are fixedly connected with the bottom ends of the corresponding limiting blocks 7, a first sealing gasket 12 is fixedly connected to the outer wall of the right side of each connecting ring 3, and a second sealing gasket 13 is fixedly connected to the bottom wall of each butt joint groove 401.
