s4: when water pipe (2) internal pressure was too big, strengthening rib (262) cooperation arc through explosion-proof layer (26) inner chamber strengthened piece (263) and tentatively strengthened water pipe (2), the too big condition that leads to water pipe (2) to break of water pressure of pre-proof pipe (2) inner chamber takes place, iron wire net layer (264) through explosion-proof body (261) outer wall can further consolidate water pipe (2), rivers that can pre-proof pipe (2) inner chamber through polyethylene anticorrosive coating (265) corrode water pipe (2) and lead to its ruptured condition to take place.
