The invention provides a plastic, concrete and
fiber composite
pipe with a reinforcing rib. The
pipe comprises a plastic plate strip, wherein the edges of the plastic plate strip are lapped or welded to form a
pipe wall; a clamping groove is formed on the plastic plate strip; the reinforcing rib is embedded into the clamping groove; a concrete cavity is formed between the outer side wall of the reinforcing rib and the inner side wall of the clamping groove; notches of the clamping groove are sealed by a sealing layer; a
fiber layer made of a
fiber mesh or a fiber strip is wound on the outer wall of the weld of the plastic plate strip; an anti-
cracking layer is formed on the outer wall of the
fiber layer through glue
coating; and concrete is filled in the concrete cavity. The pipe has the advantages that: 1, the concrete is poured into a hollow
ridge, and a reinforcing rib steel strip is not required to be wound any more, so that raw materials are saved, and the production cost of the pipe is greatly reduced; 2, the outer wall of the weld is coated with the
fiber layer, so that the
pressure resistance of the weld of the plastic plate strip is greatly improved; 3, after the steel strip is arranged, the
pressure resistance of the pipe is greatly improved; and 4, by rolling a hole on the steel strip, the concrete, the steel strip and the plastic plate strip can be well combined into a body, an expansion and contraction coefficient among different materials is reduced, the pipe is effectively prevented from being cracked or deformed, and the reinforcing rib is prevented from being rusted.
