Abstract
The invention relates to a prestressed steel-cylinder concrete pipe with a steel socket and a steel spigot, comprising a socket, a spigot, a concrete pipe core, a steel cylinder, a prestressed steel wire and a protecting layer, wherein a connecting steel ring is respectively fixedly installed at two ends of the steel cylinder between the steel cylinder and the spigot and the socket in the radial direction. Through improvement, the invention still has excellent impermeability, corrosion resistance, prevention of non-uniform settlement, low cost of raw material and construction, simple construction process and convenient maintenance and can omit an external mould and control the wall thickness of the concrete pipe, thereby saving the production cost, reducing steps of forming a concrete pipecore and improving the production efficiency.
Description
Technical field
The present invention relates to concrete plug, especially a kind of prestressed steel-cylinder concrete pipe with steel socket and spigot.
Background technique
Widely used prestressed steel-cylinder concrete pipe with steel socket and spigot in large-scale liquid conveying engineering, owing to being inlaid with a steel cylinder and this steel cylinder two ends coaxial directly being packed on steel bell and socket respectively at this concrete pipe in-core, thereby make whole concrete pipe self form an airtight integral body, therefore efficiently solve because carrying fluid pressure to cause the problem of carrying liquid to be exosmosed by concrete tube wall.There is following problem in existing prestressed steel-cylinder concrete pipe with steel socket and spigot in manufacture process: 1. the concrete tube core comes molded by interior external mold, because interior external mold customizes, therefore internal mold and the distance between external mold of pipe die are a fixed value, the engineering of corresponding different operating modes and the different operating modes of same engineering can only be carried out by the pitch regulated of reinforcement wire the fine setting of tube core wall thickness, and the moulding process of this inside and outside modular form can not be suitable for the concrete pipe that the tube core wall thickness is arbitrarily adjusted; 2. the pipe die cost that is used for the formation of concrete tube core is higher, the external mold in pipe die especially, and its weight accounts for 1/3 of a whole set of pipe die, and cost of production is higher; 3. in the moulding process of whole prestressed steel-cylinder concrete pipe with steel socket and spigot, concrete tube core molding time is longer, and the tube core moulding needs external mold, internal mold, bed die and backform to cooperatively interact, and lifting each pipe die all needs time of growing, and manufacturing efficiency is lower.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of prestressed steel-cylinder concrete pipe with steel socket and spigot is provided; This concrete pipe can save external mold in forming process, saved cost of production, has reduced the process step of concrete tube core moulding, has improved manufacturing efficiency.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of prestressed steel-cylinder concrete pipe with steel socket and spigot; consisted of by bellmouth, socket, concrete tube core, steel cylinder, reinforcement wire and protective layer; bellmouth and socket be the coaxial two ends that are packed in the concrete tube core respectively; steel cylinder is packed on the outer wall of concrete tube core; the outer wall of steel cylinder is fixed with protective layer; be wound with reinforcement wire on outer wall in the steel cylinder protective layer, wherein be fixed with respectively diametrically one in the end positions of steel cylinder between steel cylinder and socket and bellmouth and be connected steel loop.
And described connection steel loop is packed in the port position at steel cylinder two ends.
And, but in the connection steel loop retraction steel cylinder port of socket position.
Advantage of the present invention and beneficial effect are:
1. the steel cylinder two-end part of this prestressed steel-cylinder concrete pipe with steel socket and spigot is packed on bellmouth and socket by connecting steel loop respectively, substitute external mold with steel cylinder, thereby saved external mold, this structural type has realized making the prestressed steel cylinder reinforced concrete pipe with steel socket and spigot of different wall by the connection steel loop that is fixedly mounted with different sizes, use amount with the concrete consumption of reasonable reduction tube core and reinforcement wire reaches the purpose that reduces costs.
2. the present invention is through still having preferably impermeability, anti-corrosive properties, resisting uneven settlement after improving, and raw material and construction cost cost are low, construction process is simple, maintenance maintenance is convenient, sharpest edges are the wall thickness that omit external mold and control concrete pipe, greatly save thus cost of production, reduced the process step of concrete tube core moulding, improved manufacturing efficiency.

Fig. 2 is that the A-A of Fig. 1 is to the cross section enlarged view;
Fig. 3 is that the B-B of Fig. 1 is to the cross section enlarged view;
Fig. 4 is that the C-C of Fig. 1 is to the cross section enlarged view.
Embodiment
The invention will be further described below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of prestressed steel-cylinder concrete pipe with steel socket and spigot; consisted of by bellmouth 8, socket 1, concrete tube core 4, steel cylinder 5, reinforcement wire 6 and protective layer 7; bellmouth and socket be the coaxial two ends that are packed in the concrete tube core all; the steel cylinder coaxial package is on concrete pipe outer core cylinder; protective layer is coaxial to be packed on steel cylinder outer wall cylinder, and reinforcement wire is wrapped on the interior steel cylinder outer wall cylinder of protective layer.Be wound with reinforcement wire on outer wall in the steel cylinder protective layer.Socket outer wall footpath upwards is shaped with 1-3 groove 2, is used for installing anticorrosion sealed rubber ring in this groove with the interface between closed conduit; Protective layer is cement mortar protective course or concrete cover.
Innovative point of the present invention is:
The end positions of steel cylinder diametrically with frame connect steel loop 3,9 mode is solidly installed with socket and bellmouth respectively, this is fixedly mounted with mode and adopts welding manner.Connect the port position that steel loop is packed in the steel cylinder two ends as shown in drawings, but for socket, connect steel loop can the retraction steel cylinder in.
Preparation process of the present invention is similar to the preparation process of PCCP, just in the moulding of concrete tube core, adopts steel cylinder to substitute external mold, thereby has save external mold; And directly make the prestressed steel cylinder reinforced concrete pipe with steel socket and spigot of different wall by the connection steel loop that is fixedly mounted with different sizes.
