Further, the semicircular pipe comprises an inner pipe body and an outer pipe body, and a plurality of axial clapboards are integrally manufactured between the inner pipe body and the outer pipe body at intervals; an annular reinforcing ring is circumferentially arranged between the inner pipe body and the outer pipe body; the arc-shaped groove is arranged at the reinforcing ring.

Furthermore, the end face of the arc-shaped groove is of a dovetail structure or a C-shaped structure; during wiring, cables are sequentially placed into the open type through grooves, and then the guide ring seat slides from one end of the arc-shaped groove to the other end of the arc-shaped groove, so that a closed loop of the open type through grooves is formed; namely, the guiding and the limiting of the cable are completed.

Furthermore, the end faces of the clamping groove and the clamping block are in a dovetail structure or a C-shaped structure which are mutually clamped and hung; the embedding groove is a square groove with a hollow top surface, the clamping block is embedded into the clamping groove from the square groove in a staggered mode, and then the clamping block is slid to enable the end surfaces of the two half circular pipes to be flush; after the embedding, the two semicircular pipes can be prevented from being separated.

Compared with the prior art, the HFZ power cable half pipe adopts a mode of embedding and then clamping, and is directly subjected to staggered clamping, the clamping is not influenced by a construction space, and the two half circular pipes can be prevented from being separated after the clamping; the inside HFZ power cable direction that can carry out of body through the guide ring seat, the construction is simple and convenient.
