Prestressed steel cylinder reinforced concrete pipe with steel socket and spigot
A reinforced concrete pipe and a concrete pipe technology are applied to a prestressed steel cylinder reinforced concrete pipe made of a steel socket and socket. It can solve the problems of concrete pipes that cannot adapt to the wall thickness of the pipe core, long molding time of the concrete pipe core, and long hoisting time, etc., so as to achieve the effect of low cost of raw materials and construction costs, omission of external molds, and production cost savings.

[0017] The present invention will be further described in detail below through specific examples. The following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.
[0018] A steel socket and socket prestressed steel cylinder reinforced concrete pipe is composed of a socket 9, a socket 1, a concrete tube core 4, a steel cylinder 6, a prestressed steel wire 7 and a protective layer 8, and the socket and the socket are fixed coaxially. At both ends of the concrete tube core, the steel cylinder is coaxially sleeved on the outer wall cylindrical surface of the concrete tube core, the protective layer is coaxially fixed on the outer cylindrical surface of the steel tube, and the prestressed steel wire is wound around the outer cylindrical surface of the steel tube in the protective layer. superior. The outer wall of the socket is provided with 1-3 grooves 2 in the radial direction, and the grooves are used to install a cor...
