The reinforcing sheet is in an arc shape, and the arc surface is in contact with the inner wall of the PVC pipe.
The reinforcement pipe and the tripod support are fixedly arranged in the PVC pipe at equal intervals; and the reinforcing pipe and the tripod support are installed in a crossed manner.
The equidistant spacing distance is 10-15 cm.
The reinforcing pipe is a rigid cylindrical pipe with the length of 5-10 cm, and the surface of the reinforcing pipe is covered with a rubber layer.
The tripod support is a triangular structure consisting of rigid rods.
The PVC pipes are fixedly connected through connecting pipes; the PVC pipe is in interference fit with the connecting pipe.
The mounting method of the anti-burst gas extraction pipe structure comprises the following steps:
step 1, fixing a reinforcing pipe and a tripod support frame on the inner wall of a PVC pipe at equal intervals; the reinforcement pipe and the tripod support are in interference fit with the inner wall of the PVC pipe;
step 2, connecting and fixing each PVC pipe through a connecting pipe; and the PVC pipe is in interference fit with the connecting pipe.
The invention has the beneficial effects that:
the reinforced pipe and the tripod support are embedded in the inner wall of the PVC pipe, so that the deformation resistance of the PVC pipe is enhanced, the gas drainage pipe has the advantages of low cost, light weight and the like, and the technical problems that the gas drainage pipe in the prior art is high in cost and inconvenient to carry and install due to too heavy weight caused by adopting a metal wire protective layer or a metal shell protective layer to increase the compression resistance, and the metal layer is easy to corrode after being placed in a drainage hole for a long time due to the fact that the drainage process is more than 6-8 months, the pressure resistance is reduced and the like are solved.
