Abstract
The utility model discloses a connection structure between two grout pipes. The connection structure comprises two grout pipes (1) to be connected, wherein a connection flange (2) is arranged on the connection ends of the two grout pipes (1) respectively; and the two connection flanges (2) are connected through a bolt (3). The connection structure disclosed by the utility model has the advantages that the grout pipes and the connection flanges are cast and formed at one time, so that the structure is simple; the two grout pipes are anchored through a flange bolt, thus the interface property is good and the construction interference is low; the two grout pipes are in anchoring rigid connection, thus the influence of the grouting pressure is little, and the repeated utilization rate and the grouting guarantee rate are high; a conventional common rubber gasket is adopted for stopping grout (water), and the requirements on material are low; and the field splicing technology is simple and reliable.
Description
Technical field
the utility model relates to the linkage structure between a kind of two grout pipes, belongs to the rolled concrete arch dam transverse joint or induces the repetition grout pipe joint interconnection technique field in the seam repetition grouting system.
Background technique
The common repetition grout pipe that adopts of
rolled concrete arch dam, present two grout pipes link together through gum sleeve, and the two grout pipe terminations of systolic pressure parcel through gum sleeve form and are connected in series.The shortcoming that adopts gum sleeve to connect is following: 1. gum sleeve need pass through and could connect the grouting steel pipe after preheating is expanded, and is not easy to on-site consolidation; 2. the grout pipe end of two series connection is groove butt joints, and the gum sleeve connection through relative flexibility is prone to phenomenons such as dislocation, the assembly unit difficult quality guarantee; 3. the quality requirement to gum sleeve is high, owing to contact with percolating water with concrete for a long time, gum sleeve is prone to corruption and aging; 4. after twice grouting pressure effect in early stage 1, gum sleeve fatiguability and be difficult to reset causes grout pipe radius off-set joint, influences the later stage grouting effect.
Summary of the invention
The purpose of
the utility model is, the linkage structure between a kind of two grout pipes is provided.Assembly unit is convenient and reliable, stress condition good, load performance is high, good endurance, can be widely used in middle and high rolled concrete arch dam transverse joint or induce the grout pipe of seam repetition grouting system to connect, to overcome the deficiency of existing technology.
The technological scheme of the utility model:
Linkage structure between
two grout pipes comprises two grout pipes to be connected; The connecting end of two grout pipes is respectively equipped with adpting flange, and two adpting flanges connect through bolt.
In the linkage structure between
aforementioned two grout pipes, be provided with sealing gasket between said two adpting flanges.
In the linkage structure between
aforementioned two grout pipes, said two adpting flanges are provided with the one group of attachment hole that is uniformly distributed with along adpting flange.
In the linkage structure between
aforementioned two grout pipes, the cast tube that said adpting flange and grout pipe are structure as a whole.
In the linkage structure between
aforementioned two grout pipes, said sealing gasket is and the corresponding ring-shaped rubber spare of adpting flange shape that the ring surface of sealing gasket is provided with the through hole corresponding with attachment hole.
In the linkage structure between
aforementioned two grout pipes, be provided with bolt in the attachment hole of said two adpting flanges and the through hole of sealing gasket, the attachment hole of two adpting flanges of bolt-through and the through hole of sealing gasket are connected with nut thread.
Compared with prior art, the utlity model has following advantage:
1, grout pipe and the moulding of adpting flange one-step casting, simple structure.
2, two grout pipes are through the flange bolt anchoring, and interface property is good, and it is little disturbed by construction.
3, two grout pipes are that anchoring is rigidly connected, and it is little influenced by grouting pressure, and recycling rate of waterused is high, and the grouting fraction is high.
4, the conventional General Purpose Rubber pad of employing end slurry (sealing), and material requirements is not high.
5, on-site consolidation simple and reliable process.

Being labeled as in
accompanying drawing: 1-grout pipe, 2-adpting flange, 3-bolt, 4-sealing gasket, 5-attachment hole, 6-through hole, 7-nut, 8-gum sleeve.
Embodiment
are done further to specify to the utility model below in conjunction with accompanying drawing and embodiment, but not as any restriction to the utility model.
Linkage structure between
a kind of two grout pipes, as depicted in figs. 1 and 2.Comprise two grout pipes 1 to be connected; The connecting end of two grout pipes 1 is respectively equipped with 2, two adpting flanges 2 of adpting flange and connects through bolt 3.Be provided with sealing gasket 4 between two adpting flanges 2.Two adpting flanges 2 are provided with the one group of attachment hole 5 that is uniformly distributed with along adpting flange 2.The cast tube that adpting flange 2 and grout pipe 1 are structure as a whole.Sealing gasket 4 is and the corresponding ring-shaped rubber spare of adpting flange 2 shapes, and the ring surface of sealing gasket 4 is provided with the through hole 6 corresponding with attachment hole 5.Be provided with bolt 3 in the attachment hole 5 of two adpting flanges 2 and the through hole 6 of sealing gasket 4, bolt 3 runs through the attachment hole 5 of two adpting flanges 2 and the through hole 6 of sealing gasket 4 is threaded with nut 7.
The utility model practical implementation process
embodiment.The utility model in the specific implementation; As depicted in figs. 1 and 2; Grout pipe 1 adopts casting technique, and adpting flange 2 one-step castings of part of the light pipe in the middle of the grout pipe 1 and end are accomplished, make in the middle of the grout pipe 1 light pipe partly and the adpting flange 2 of end fuse.Adpting flange 2 is provided with three attachment holes 5 that are uniformly distributed with along adpting flange 2.When two grout pipes 1 connect; Ring-shaped rubber spare of pad is as sealing gasket 4 between the adpting flange 2 of two grout pipes 1; Sealing gasket 4 is provided with and adpting flange 2 corresponding through holes 6; Be applied in the through hole 6 of attachment hole 5 and sealing gasket 4 of two adpting flanges 2 with three bolts 3 then, at the bolt 3 threaded end nut 7 of screwing on, with two grout pipes 1 linking together tightly.
