Faucet prestressed reinforcement pipes of concrete made by novel section steel

Abstract

The invention relates to a novel prestressed concrete reinforced pipe with a steel bell and faucet, and consists of a bell mouth, a faucet, a concrete reinforced pipe core, a framework of steel reinforcement, a prestressed steel wire and a protection layer; wherein, the bell mouth and the faucet are fixedly arranged at the two ends of the concrete reinforced pipe core respectively; the framework of steel reinforcement is embedded in the concrete reinforced pipe core with the wall fixedly provided with a protection layer; the prestressed steel wire wines around the outer wall of the concrete reinforced pipe core under the protection layer; wherein, an inner ring station is coaxially fixed on the inner wall of the bell mouth coaxially fixed at one side of the concrete reinforced pipe core. The invention has the advantages of simple integral structure, scientific and reasonable design, good durability, good impermeability, good joint sealing property, relatively low construction cost, convenient maintenance, simple construction and operation and reduced construction cost, thereby being a high-creative novel prestressed concrete reinforced pipe with a steel bell and faucet.

Description

technical field [0001] The invention relates to a concrete pipe, in particular to a novel steel socket prestressed reinforced concrete pipe. Background technique [0002] At present, concrete pipes are mainly classified according to the interface form: 1. Flat concrete; 2. Tongue concrete pipe; 3. Socket concrete pipe. The interface form of the pipe is one of the main links that determine the airtightness of the entire pipeline; the socket of the concrete pipe is generally divided into two types according to the material: 1. Concrete material, the socket and the concrete pipe core are integrally cast; 2. Steel material, steel The sockets are fixed on both ends of the concrete pipe core. At present, steel sockets are mostly used for large-diameter concrete pipes. The advantages are reflected in the high strength of steel sockets, strong anti-collision ability, convenient installation, simple construction operation, and strong impermeability. Generally, the outer wall of the...

AI Technical Summary

Problems solved by technology

Generally, the outer wall of the steel socket socket is a single-slot or double-slot structure, which is forged and formed, and a sealing ring is provided in the groove. Although the sealing effect can be achieved, the socket of this structure has complicated manufacturing process and high production cost.
