Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of ultrathin steel-socket prestress steel-cylinder steel-fiber concrete pipe is provided, this concrete pipe scientific structure design is reasonable, save material, the tube core wall thickness is thinner, impervious, resistance to cracking is better, the lifting, convenient transportation, construction cost is lower.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of ultrathin steel-socket prestress steel-cylinder steel-fiber concrete pipe; constitute by bellmouth, socket, steel cylinder, steel fiber concrete pipe core, reinforcement wire, protective layer; wherein bellmouth and the coaxial respectively two ends that are packed in the steel fiber concrete pipe core of socket; steel cylinder is coaxial to be inlaid in the steel fiber concrete pipe in-core and its two ends are coaxial respectively is packed on bellmouth and the socket; reinforcement wire is wrapped on the steel fiber concrete pipe outer core under the protective layer, wherein
(1). the ratio of steel fiber concrete pipe core wall thickness d and this tube core inside diameter D is μ, and 1/60≤μ≤1/32;
(2). the pitch of reinforcement wire is that this prestress steel filament diameter is φ mm, and 2 φ≤≤ 50.
And the span of described reinforcement wire diameter phi is 3≤φ≤10.
And, coaxial diametrically 2～3 seal grooves that are shaped on of described socket outer wall.
And described protective layer is a slush.
Advantage of the present utility model and beneficial effect are:
1. the steel fiber concrete pipe core of this concrete pipe is by the Steel Fiber Reinforced Concrete one-time cast-forming, and the steel fiber concrete pipe in-core is embedded with steel cylinder, has impermeability and resistance to cracking preferably.
This concrete pipe scientific design the thickness of tube core, make full use of the characteristic of Steel Fiber Reinforced Concrete, steel cylinder and reinforcement wire, not only make whole steel fiber concrete pipe core wall thickness reduce to below 1/32 of homogeneous tube internal diameter, and tubing weight also only is with 1/2 to 3/4 of the existing tubing of bore, reduce cost of transportation, installation cost and the bypass of tubing widely and laid cost, solved the problem of existing heavy caliber pipe lifting difficulty.
3. this concrete pipe also adopts flexible faucet structure, have good joint Watertightness, and constructing operation is easy; Because this tube material and tube wall is thinner, the body own wt is lighter, has also improved the ability of opposing uneven settlement to a certain extent.
4. the utility model scientific structure design is reasonable, saves material, and the tube core wall thickness is thinner, and is impervious, resistance to cracking is better, is a kind of lifting, convenient transportation, ultrathin steel-socket prestress steel-cylinder steel-fiber concrete pipe that construction cost is lower.
