Detailed Description
To further disclose the contents, features and functions of the present invention, the following examples are given in detail in conjunction with the accompanying drawings.
A drain pipe for a retaining wall of hydraulic engineering comprises a pipe body, a first water stop ring, a second water stop ring and an elbow, wherein the drain pipe is positioned in a permeable hole in the retaining wall; the length of the pipe body is equal to the thickness of the retaining wall; the pipe body, the first water stop ring and the second water stop ring are of an integrated structure; the first water stop ring and the second water stop ring are both composed of two circular rings protruding out of the pipe body, and the outer diameter of each circular ring is equal to the inner diameter of the water permeable hole; the first water stop ring is positioned at one end of the pipe body and connected with the elbow, and the elbow extends out of the retaining wall from the water permeable hole; the second water stop ring is positioned in the middle of the pipe body. The drain pipe is a pvc pipe. The elbow is elbow bend or is 45 degrees's slope elbow with the barricade. And annular ribs are arranged in the middle of the first water stop ring and the middle of the second water stop ring. The drain pipe and the retaining wall are integrally cast.
Example 1: referring to fig. 1, a water drainage pipe 9 for a retaining wall of hydraulic engineering comprises a pipe body 1, a first water stop ring 2, a second water stop ring 3 and an elbow 4, wherein the water drainage pipe 9 is positioned in a water permeable hole 6 in the retaining wall 5; the length of the pipe body 1 is equal to the thickness of the retaining wall 5 by 240 mm; the pipe body 1, the first water stop ring 2 and the second water stop ring 3 are of an integrated structure; the first water stop ring 2 and the second water stop ring 3 are both formed by two circular rings protruding out of the pipe body 1, and the outer diameter of each circular ring is equal to the inner diameter of the water permeable hole 6 by 50 mm; the first water stop ring 2 is positioned at one end of the pipe body 1 and connected with the elbow 4, the elbow 4 is positioned in the pipe body 1 and is bonded and fixed by an adhesive, and the elbow 4 extends out of the retaining wall 5 from the water permeable hole 6; the second water stop ring 3 is positioned in the middle of the pipe body 1.
