[0011] Further, the first upper half pipe and the second upper half pipe are not equal in length, and one end of the first upper half pipe is provided with a half pipe plug-in connector, which is inserted into the second upper half pipe to be connected and positioned.

[0012] Further, the first lower half pipe and the second lower half pipe are not equal in length, and one end of the second lower half pipe is provided with a half pipe plug-in connector, which is inserted into the first lower half pipe to be connected and positioned.

[0013] Further, the threading hole is provided with an arc-shaped chamfer.

[0014] Further, a plurality of guide strips are arranged on the half pipe plug-in connector.

[0015] Further, a hoop is arranged between the upper half pipe assembly and the lower half pipe assembly for reinforcement.

[0016] By adopting the technical scheme, the cable protection pipe has the advantages that the structure is simple and convenient to disassemble and assemble, the strength is high, the cable can be effectively protected to avoid safety accidents, and the cable protection pipe can be used for protecting the cable in the installed manhole or during the installation of a new well.
