[0004] Most of the existing PVC pipes are buried in the ground. The above patent has the advantage of being resistant to pressure by using an elastic pipe, an elastic fiber net and a reinforcement layer. When the PVC pipe is hit or squeezed by an external force, the external force can be absorbed to avoid the pipe body from rupturing and affecting the use of the PVC pipe. The pipe can be effectively protected in the ground, but the connection ports are mostly weak and can easily be disconnected due to excessive pressure, which can easily cause some parts to break. For this reason, we propose a pressure-resistant PVC pipe. Utility Model Content
