It is used in construction projects such as laying pipelines and cables in special areas such as roads, railways, buildings, and under riverbeds. MPP power cable protection pipe is also called MPP power pipe and MPP cable pipe. The raw material is PP powder (modified polypropylene) as the main masterbatch. MPP power cable protection pipe is divided into ordinary type and reinforced type. The reinforced type is divided into trench pipe and trenchless pipe.

[0023] The reinforcing block 2 includes an embedded block 201, a stop block 202, a guide rod 205 and a spring 206. The stop block 202 is fixedly installed on the upper and lower surfaces of the front end of the embedded block 201. The front surface of the stop block 202 is provided with a socket 207. The interior of the embedded block 201 is provided with a receiving groove 203, and the receiving groove 203 can receive the squeezed positioning block 3; the inner two side surfaces of the receiving groove 203 are laterally provided with limited sliding grooves 204, and the inner rear surface of the receiving groove 203 is fixedly installed with a guide rod 205, and the surface of the guide rod 205 is sleeved with a spring 206, and the spring 206 has a forward thrust on the positioning block 3; the interior of the positioning block 3 is provided with a guide hole 301, and the rear end of the positioning block 3 The limiting slider 302 is fixedly installed on the two side surfaces; the positioning block 3 is movably embedded in the storage groove 203, the front end of the guide rod 205 extends into the guide hole 301, and the limiting slider 302 is embedded in the limiting slide groove 204. The cooperation between the limiting slide groove 204 and the limiting slider 302 can prevent the positioning block 3 from escaping from the storage groove 203; the two side surfaces of the tube body 1 are provided with a stop groove 101, the rear surface of the stop groove 101 is provided with a mounting groove 102, and the rear surface of the stop groove 101 and the upper and lower sides of the mounting groove 102 are provided with threaded grooves 103; the rear end of the fastener 4 passes through the plug hole 207 and is embedded in the threaded groove 103, and the embedding block 201 is embedded in the mounting groove 102.
