Protective device during transportation of plastic pipes

The invention discloses a protective device during transportation of plastic pipes. The protective device comprises a protective pipe, wherein the protective pipe is of a double-layer structure which is composed of an inner pipe body and an outer pipe body, a plurality of tubular protective cavities are uniformly distributed between the inner pipe body and the outer pipe body along the circumferential direction, gaps between adjacent protective cavities are filled with spongy pads, and the spongy pads are used for connecting the inner pipe body with the outer pipe body. The protective device has the advantages of simple structure and convenience in use; when the protective device is used, the plastic pipes are inserted into the protective cavities or the inner pipe body, so that the plastic pipes cannot extrude and collide during transportation, and the plastic pipes are prevented from being damaged or deformed. 本发明公开了种塑料管运输过程中的保护装置，包括保护管，保护管是由内管体和外管体组成的双层结构，在内、外管体之间沿圆周方向均布设置有若干管状防护腔，并且相邻防护腔之间填充有海绵层垫，所述海绵层垫用于
