The invention discloses a socket joint type spiral corrugated pipe made of steel strips and reinforced polyethylene, which can realize rapid connection on a construction site, as well as a connector, and connection method of the socket joint type spiral corrugated pipe. The socket joint type spiral corrugated pipe mainly comprises socket joints, bellmouths and pipes, wherein the connector structure of the corrugated pipe is formed by the sockets and the bellmouths; flat end mouths are respectively formed in two ends of each of the bellmouths and the sockets; one end connected with one pipe, of each of the sockets and the bellmouths, is provided with a flat straight section with a certain length and a spiral dislocation step; a groove which can allow a sealing rubber gasket to be accommodated is formed in the other end of each socket; guide planes are respectively arranged at the front end and the rear end of the groove in each socket. The connecting method comprises the following steps: the bell mouths and the sockets are respectively matched with the pipes in a welded sealing manner or an adhesive sealing manner, and then, each bellmouth and the corresponding socket are connected in an abutting manner by utilizing an axial advancing device, so that a high-efficiency method for mounting the spiral corrugated pipe made of steel strips and reinforced polyethylene without electricity or fire on the construction site is realized.
Description
technical field [0001] The invention relates to a connection structure and an installation method of a steel strip reinforced polyethylene spiral corrugated pipe, in particular to a socket type steel strip reinforced polyethylene spiral corrugated pipe and its joint and connection method. Background technique [0002] The steel belt reinforced polyethylene spiral corrugated pipe integrates the high rigidity of the steel belt and the corrosion resistance, low friction resistance, and wear resistance of polyethylene. It has high ring stiffness, is buried deeper than all plastic pipes, and is overall The forming process is good, the seam tensile strength and anti-corrosion are high, and the service life is longer; it has a variety of reliable and convenient connection methods. Compared with pipes of the same diameter and same ring stiffness level, it not only has excellent performance but also has a particularly low cost and higher cost performance. Therefore, this kind of pip...
