Abstract
The utility model discloses a connection structure for between spiral corrugated steel pipe, two near -end faces of two section adjacent spiral corrugated steel pipe are established to the plane along its periphery, and just two planar incline directions keep unanimous, simultaneously two near -end faces are through at least a set of angle steel flange and a plurality of bolt tube coupling end flange joint of group in order to accomplish the connection between spiral corrugated steel pipe tube coupling, wherein, every near -end face all is connected with the first side of an angle steel flange, should organize the second side interconnect that the angle steel flange is adjacent. The advantage not only makes things convenient for the reliable connection between the spiral corrugated steel pipe tube coupling for this connection structure, and the leakproofness improves greatly moreover, and construction and installation convenient and fast.
Description
Technical field
The utility model relates to a kind of for the linkage structure between spiral corrugated steel pipes.
Background technique
Conventional pipelines, as cast iron tube, welded pipe, cement pipe, plastic tube, it mainly adopts the Placements such as bayonet joint, dock connection, dike field, but the reliability of this several Placement and sealing are not high, and as thermal shrinkable sleeve connects, then intensity is low, construction requirement is high for other.
Spiral corrugated steel pipes upgrades to conventional pipelines the ideal product substituted.But due to the end surface helically corrugated of spiral corrugated steel pipes, and general bindiny mechanism's form is difficult to meet the high request of spiral corrugated steel pipes to intensity and sealing, therefore the reliability of this steel pipe connection between pipe sections and sealing become the major issue faced in whole pipe-line system.Meanwhile, spiral corrugated steel pipes because various factors, cannot ensure that in the section that tube coupling is all, caliber is completely the same in course of working, cause some spiral corrugated steel pipes when connecting because of joint caliber difference, sealing effect is poor.
Model utility content
Goal of the invention: the utility model is overcome the poor drawback of sealing effect and reliability between spiral corrugated steel pipes, provides a kind of novel new Joining Structure for spiral corrugated steel pipes.
Summary of the invention: of the present invention for the linkage structure between spiral corrugated steel pipes, two proximal end faces of adjacent two joint spiral corrugated steel pipes are set to plane along its periphery, and the true dip direction of two planes is consistent, simultaneously described two proximal end faces by least one group of angle steel flange and some groups of bolt tube coupling termination Flange joint to complete the connection between spiral corrugated steel pipes tube coupling; Wherein, each proximal end face is all connected with the first side of an angle steel flange, and the second side that this group angle steel flange is adjacent is interconnected.
Wherein, preferably, described plane is arranged in horizontal direction.
Described two proximal end faces are connected by two groups of angle steel flanges, and these two groups of angle steel flanges are arranged along the radial symmetric of proximal end face.
Further, the first side of described proximal end face and angle steel flange is bolted, and arranges sealing gasket between this proximal end face and angle steel flange.
Preferably, connected by axial bolts between the second side that described one group of angle steel flange is adjacent, and sealing gasket is set between this second side.Meanwhile, some axial bolts can be set according to pipe diameter size.
Described sealing gasket is rubber seal.
Described bolt is high-strength bolt; Meanwhile, described axial bolts is high-strength bolt.
Beneficial effect: compared with prior art, its advantage is the utility model: the proximal end face surface of spiral corrugated steel pipes flattens, and the proximal end face intimate surface of angle steel flange and steel pipe is fitted, not only convenient connection, and sealing improves greatly; Secondly, the mode connected by angle steel flange etc. between spiral corrugated steel pipes does not destroy the surface quality of spiral corrugated steel pipes, simultaneously effective proof strength; Meanwhile, on flange second side (flange), arrange that wearing of some joins hole respectively according to the diameter of spiral corrugated steel pipes, the requirement of different densities, join strength can be met like this, realize the reliable connection between spiral corrugated steel pipes.
Accompanying drawing explanation
Fig. 1 is the structural representation after the proximal end face of single-unit spiral corrugated steel pipes flattens;
Fig. 2 is the structural representation that adjacent two joint spiral corrugated steel pipes connect;
Fig. 3 is the enlarged view of A point in Fig. 2.
Embodiment
Below in conjunction with accompanying drawing 1-3, the technical solution of the utility model is described further.
As shown in Figure 1, the proximal end face 2 of spiral corrugated steel pipes 1 is set to a circle plane along its periphery, and this proximal end face 2 is connected with the first side 31 of an angle steel flange 3, and specifically fix by bolt 5, preferably, this bolt 5 is selected from the one in high-strength bolt.
As Figure 2-3, adjoining spiral corrugated steel tube 1, the true dip direction of two planes of two proximal end face 2 is consistent, and preferably, described plane is arranged in horizontal direction, or two planes are oblique arranges.Two proximal end faces are by least one group of angle steel flange 3 and some groups of bolt tube coupling termination Flange joint simultaneously.Wherein, the second side 32 often organizing angle steel flange 3 adjacent is interconnected, specifically, can be connected by axial bolts 7, and the quantity of axial bolts 7 can be arranged according to pipe diameter size, if caliber is comparatively large, axial bolts 7 can arrange multiple, if caliber is less, the quantity of axial bolts 7 can suitably reduce.
Preferably, described two proximal end faces 2 are connected by two groups of angle steel flanges 3, and these two groups of angle steel flanges are arranged along the radial symmetric of proximal end face, so can ensure the join strength between spiral corrugated steel pipes.If caliber is comparatively large, angle steel flange 3 can arrange many groups.
In order to strengthen sealing effect further, sealing gasket 6 being set between this proximal end face and angle steel flange, being preferably rubber seal.
Same, between the second side 32 that described one group of angle steel flange 3 is adjacent, sealing gasket 6 is set, is preferably rubber seal.
Working process: for reducing the connection difficulty of spiral corrugated steel pipes joint, when production and processing, first utilize special device that the end surface (40mm ~ 50mm) of every root spiral corrugated steel pipes is made into unrippled flat board (proximal end face), then the first side of angle steel flange and the planar section of proximal end face are fitted tightly, and use hydraulic pressure punch device, punching on angle steel flange and steel plate.Use bolt fixed angles steel flange at this hole place, circumferentially strain with bolt tube coupling termination flange when splicing and connect; Uniform bolt hole is stamped in the second side (flange) that connection between each section of spiral corrugated steel pipes then relies on angle steel flange, with high-strength bolt two end flange are strained vertically and connect, with rubber seal rings for seal (it should be noted that also must stamp corresponding hole according to the bolt hole of flange edge in rubber seal) between flange facing.
