[0002] In the field of infrastructure construction such as electric power, communication, cable protection pipe as an important component to protect cable, its performance and quality are directly related to the safe operation and service life of cable. As a new type of cable protection pipe, polypropylene composite MPP cable protection pipe is widely used in various cable laying engineering because of its good mechanical properties, corrosion resistance and aging resistance.

[0003] However, in practical application, polypropylene composite MPP cable protection pipe has some problems in storage and transportation. On the one hand, the two ends of the cable protection pipe are in an open state, which is easy to cause foreign matter to enter the pipe, affect the laying quality of the cable, and even cause damage to the cable. On the other hand, when stacking cable protection pipe, due to the lack of effective support and protection of the pipe opening, the pipe opening part is easy to be deformed by external force, which reduces the overall performance and service life of the cable protection pipe.

[0004] In order to solve the above problems, the existing technical solution usually adopts the way of installing plug or sealing cover at both ends of the cable protection pipe. But these plugs or sealing covers are mostly simple in structure, and are fixed in the pipe opening by simple plug-in or threaded connection, which is not firm enough, and is easy to fall off during use, so it cannot effectively guarantee the sealing performance and pressure resistance of the pipe opening. In addition, the existing plug or sealing cover is difficult to neatly store after removal, which is easy to be lost or damaged, and increases the use cost.

[0005] Therefore, it is of great practical significance to develop a polypropylene composite MPP cable protection pipe with stop structure, which can be firmly fixed in the pipe opening, effectively prevent foreign matter from entering and the pipe opening from deforming, and be convenient to remove and store.

At this time, the sealing cover 2 can be easily pulled out of the end port of the polypropylene composite MPP cable protection pipe body 1. After the sealing cover 2 is removed, if it is necessary to store it, a plurality of sealing covers 2 can be stacked through the stacking groove 11. The stacking groove 11 is a circular groove, which is opened at one end of the sealing cover 2, and the side wall of the stacking groove 11 is fixed with a rubber ring 12. The top end of one sealing cover 2 is inserted into the stacking groove 11 at the bottom end of another sealing cover 2, and in the insertion process, the rubber ring 12 is clamped between the sealing cover 2 and the stacking groove 11, and is elastically deformed, which plays a buffering and fixing role, and ensures that a plurality of sealing covers 2 can be aligned and stable when stacked. In this way, the sealing cover 2 can be neatly stacked, which is convenient for storage and subsequent use. Through the above use method, the sealing cover 2 with the sealing structure of the polypropylene composite MPP cable protection pipe can fully play its function, realize the sealing and pressure protection of the cable protection pipe port, and realize the recycling and convenient storage of the sealing cover 2.
