The utility model is further arranged in such a way that the outer wall of the reinforcing pipe is provided with a regular triangle column structure, and the distance between the structures is equal to two times of the side length of the regular triangle.

Through adopting above-mentioned technical scheme, the structure that utilizes regular triangle improves the compressive capacity of perpendicular, and the distance that will keep the twice length of a side of regular triangle between every structure makes the partial protecting tube of protecting against shock of giving of atress decentralization, reduces the pressure that the individual layer protection pipe receives.

The utility model is further configured in such a way that no gap can be left between the reinforcing pipe and the outer pipe by the reinforcing pipe protective layer, and no gap can be left between the impact-resistant inner pipe and the reinforcing pipe by the inner pipe protective layer.

Through adopting above-mentioned technical scheme, when guaranteeing to receive the impact, can not have the space to lead to the atress inequality to cause the protection tube impaired for the centre, ensure simultaneously that the protection tube is impaired the back, can drag damaged piece can not fish tail inner cable.

In summary, the utility model mainly has the following beneficial effects:

1. according to the utility model, the impact force applied to the outside is resisted by the three-layer PVC structure of the anti-impact inner pipe, the reinforcing pipe and the outer pipe, the impact force of the horizontal plane is resisted by the semicircular structure of the anti-impact pipe, the impact force in the vertical direction is resisted by the reinforcing pipe, and finally, all external influences are blocked by the outer pipe, so that the impact force is faced firstly, thus multiple protection and impact resistance are realized, the problem of single structure of the existing protection pipe is solved, and the pressure resistance of the protection pipe is greatly improved;

2. according to the utility model, the TPU material modified by the glass fiber of the inner pipe protective layer and the reinforcing pipe protective layer is used for protecting the PVC pipe from being broken, and the TPU material cannot be broken as brittle as PVC because the toughness of the TPU material is higher than that of PVC, and cannot form fragments with high hardness to scratch a cable in a pipeline after the TPU material protective layer is broken because the hardness of the TPU material is lower than that of PVC, so that a crack-shaped protective layer is formed to protect the inner cable.
