[0002] With the continuous development of the economy, the connection and installation methods of engineering drainage pipes are also constantly upgraded. After the drainage pipes have been used for a period of time, the pipe connections need to be inspected and maintained. At present, engineering drainage pipes are installed and fixed by threaded connection or clamping.

[0003] The threaded connection method is to set matching threads at the connection of the two pipes. The direct threaded connection is subject to the impact of water during use, and the pipe connection will still be loose later; the clamping method is relatively simple, fixed by a clamping block and a clamping slot. This installation method is convenient and fast during the installation process, but there are certain disadvantages during later maintenance. After the two pipes are connected, it is not convenient to disassemble and repair. During the disassembly and maintenance process, the clamping parts are easily damaged, and repeated clamping operations are easy to loosen. In view of this, the present application proposes an engineering drainage pipe that is easy to install. Summary of the invention

[0035] It also includes a fixing ring 3 fixedly sleeved on the connecting end of the first water pipe 1, and a connecting ring 10 is rotatably sleeved on one end of the second water pipe 2 close to the fixing ring 3; a plurality of directional grooves 8 are provided at the end of the fixing ring 3, and a directional piece 9 corresponding to the plurality of directional grooves 8 is provided on the end of the connecting ring 10 close to the fixing ring 3, which is used to clamp the fixing ring 3 and the connecting ring 10, and can be reversibly disassembled; a pair of guide holes 6 are provided on the side wall of the fixing ring 3, and a pair of guide rods 7 are fixedly connected to one end of the connecting ring 10 close to the fixing ring 3, and the length of the guide rod 7 is greater than the length of the threaded pipe 5. The guide rod 7 can be inserted into the guide hole 6 and is slidably connected to the guide hole 6. When the first water pipe 1 and the second water pipe 2 are connected, the guide rod 7 is inserted into the guide hole 6, which can position the direction of the fixing ring 3 and the connecting ring 10, so that after the first water pipe 1 and the second water pipe 2 are threadedly connected, the plurality of directional pieces 9 are respectively inserted into the plurality of directional grooves 8.

[0036] Specifically, the orienting member 9 includes a connecting tube 91 arranged at the end of the connecting ring 10, a locking block 93 is slidably arranged through one side of the connecting tube 91, and a locking hole 81 matching the locking block 93 is opened on the side wall of the orienting groove 8.
