The reinforced concrete pipe can effectively resist ground settlement and is simple in structure, scientific and reasonable in design, good in overall sealing performance, simple in manufacturing process, low in cost, and is safe and reliable.
Description
Technical field
The present invention relates to the concrete pipe field, especially a kind of concrete reinforced pipe with the prestressed pipe base.
Background technique
The existing concrete tubular construction mainly comprises bellmouth, socket, Framework Of Steel Reinforcement and concrete tube core, and bellmouth and socket are packed in concrete tube core two ends respectively, and Framework Of Steel Reinforcement is inlaid in the concrete pipe in-core and its two ends are packed in respectively on bellmouth and the socket; The concrete pipe of this structure need be done concrete foundation or native arc basis when construction and installation; Soil arc basis comprises flat base of plain soil and sand-gravel cushion basis etc., has increased the engineering time like this, has improved construction cost; Reduced efficiency of construction; Structurally this tubing Framework Of Steel Reinforcement generally needs bilayer to guarantee structure stress safety in addition, and rolled steel dosage is bigger, and cost is higher.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing technology, a kind of concrete reinforced pipe with the prestressed pipe base is provided, this concrete pipe is simple in structure, and design science is reasonable, can effectively resist foundation settlement, and overall sealing performance is good, makes simply, and cost is lower.
The present invention solves its technical problem and realizes through following technological scheme:
A kind of concrete reinforced pipe with the prestressed pipe base; Comprise bellmouth, socket, Framework Of Steel Reinforcement and concrete tube core; Bellmouth and socket are packed in concrete tube core two ends respectively; Framework Of Steel Reinforcement is inlaid in the concrete pipe in-core and its two ends are packed in respectively on bellmouth and the socket, its in concrete tube core bottom one make a pipe base, the setting-in pre-stressed longitudinal is to reinforcing bar in this Guan Ji.
And described Framework Of Steel Reinforcement is made up of oval ring reinforcing bar and vertical muscle.
And the long diameter of described oval ring reinforcing bar is parallel to the pipe basal surface.
And the coaxial footpath of described socket outer wall upwards is shaped on 1-3 groove.
Advantage of the present invention and beneficial effect are:
1, the concrete reinforced pipe of this band prestressed pipe base in concrete tube core bottom one make a pipe base; The setting-in pre-stressed longitudinal is to reinforcing bar in this Guan Ji; This structure need not done concrete foundation or native arc basis in duct bottom; Practiced thrift construction cost, improved efficiency of construction, the advantage aspect construction is very big.
2, the Framework Of Steel Reinforcement of the concrete reinforced pipe of this band prestressed pipe base is made up of oval ring reinforcing bar and vertical muscle, and the long diameter of oval ring reinforcing bar is parallel to the pipe basal surface, has avoided double-deck arrangement of reinforcement, has practiced thrift steel.
3, the coaxial footpath of socket outer wall of the concrete reinforced pipe of this band prestressed pipe base upwards is shaped on 1-3 groove, O-ring seal can be installed in this groove be used to seal the slit between bellmouth and the socket, and this interface shape can guarantee that pipeline rotates to an angle and still has good sealing; When groove is 2 when above; Can between groove, punch, be used for the interface hydrostatic test, avoid pipe interior poured water and suppressed; Time saving and energy saving, the conserve water resource.
4, the present invention is simple in structure, and design science is reasonable, can effectively resist foundation settlement, and overall sealing performance is good, makes simply, and cost is lower, is a kind of concrete reinforced pipe of safe and reliable band prestressed pipe base.

Embodiment
Through specific embodiment the present invention is made further detailed description below, following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A kind of concrete reinforced pipe with the prestressed pipe base; Comprise bellmouth 6, socket 1, Framework Of Steel Reinforcement and concrete tube core 3, bellmouth and socket are packed in concrete tube core two ends respectively, and Framework Of Steel Reinforcement is inlaid in the concrete pipe in-core and its two ends are packed in respectively on bellmouth and the socket; The coaxial footpath of socket outer wall upwards is shaped on 1-3 groove 2; Groove shown in the present embodiment is 2, its in concrete tube core bottom one make a pipe base 8, the setting-in pre-stressed longitudinal is to reinforcing bar 7 in this Guan Ji; Framework Of Steel Reinforcement is made up of oval ring reinforcing bar 5 and vertical muscle 4, and the long diameter of oval ring reinforcing bar is parallel to the pipe basal surface.
Concrete tube core of the present invention and Guan Ji build and are integral, and need not do concrete foundation or native arc basis in duct bottom, and the Framework Of Steel Reinforcement of this concrete pipe in-core is made up of oval ring reinforcing bar and vertical muscle in addition; The long diameter of oval ring reinforcing bar is parallel to the pipe basal surface; After this pipe laying was accomplished, stressing conditions was that the inside, cross section of pipeline top and bottom is the tensile region, i.e. concrete in tension; Outside compressive region, i.e. concrete compression; The inside, cross section of pipeline both sides is compressive regions, i.e. concrete compression, and the outside is the tensile region; Be concrete in tension, in tubing, concrete mainly bears pressure; Reinforcing bar mainly bears pulling force, during concrete compression, is not need reinforcing bar to strengthen; And during concrete in tension, because of concrete in tension ability extreme difference, so must there be reinforcing bar to strengthen.Based on above-mentioned force analysis; Can find out that if the direction that tubing is installed is uncertain, promptly any one of pipe radially all will be according to stressed least favorable arrangement of reinforcement; And general caliber is greater than the concrete reinforced pipe of DN1000mm; All need adopt double-deck arrangement of reinforcement, promptly dispose one deck reinforcing bar respectively near inner and outer wall, this is the technological general knowledge of knowing most.Framework Of Steel Reinforcement of the present invention is according to the stress condition arrangement of reinforcement; The scheme of taking has just been saved a large amount of steel; Be pipe top and bottom only near the internal configurations reinforcing bar, the both sides of pipe are configuration reinforcement externally only, just only need just can satisfy the stressed needs of pipe at the concrete tensile region of tube wall configuration reinforcement; The character of reinforcing bar promptly becomes ellipticity, and is as shown in the figure.The reinforcing bar of saving in theory reaches more than 50%, and actual the saving also can reach 40%.
The prestressing force longitudinal steel bar of setting-in applies through pretensioning system in the Guan Ji of the present invention, pretensioned steel just, and concreting then, concrete is decontroled the fixedly ground tackle of reinforcing bar after reaching certain intensity again, makes concrete under the pulling force of reinforcing bar, receive pulling force.Pre-stressed longitudinal in pipe base portion position, can effectively be resisted the shearing that tubing receives to steel bar arrangement, makes pipe be unlikely to fracture; Particularly in the coastal area or the area of the bad earth bearing strength difference of soil property; Mounted pipeline is easy to take place uneven settlement, and uneven settlement is very big to the collapsing force of tubing, behind the employing prestressing force longitudinal steel bar; Can improve the shearing that the tubing opposing produces tubing because of uneven settlement greatly, guarantee that the long-term safety of tubing is used.
