Between be equipped with steel cushion block, set annular steel form on the outside of upper pier stud and lower pier stud junction, the annular steel form and upper pier
Gasket is set between column and lower pier stud, is equipped with grout pipe in lower pier stud, one end of the grout pipe extends to the splicing of lower pier stud
One or more air discharge duct is reserved in face on the Mosaic face of upper pier stud, and in grouting, the air in splicing seams is in air discharge duct discharge
Pier stud.
Further, air discharge duct is that intermediate low both sides are high, and both sides air discharge duct extends to pier stud edge, the upward pier of air
Column both sides are gradually discharged.
Further, air discharge duct is that intermediate high both sides are low, and set the exhaust grout outlet outside connection in air discharge duct highest point,
Air is finally along the exhaust grout outlet discharge being arranged in air discharge duct highest point.
Further, air discharge duct is unidirectionally arranged in suitable bridge to either direction across bridge or both direction is all arranged.
Further, air discharge duct top edge air discharge duct length direction can be the intermediate high both sides such as broken line, circular curve, parabola
The high line style in low or intermediate low both sides.
Further, the inclined-plane with certain slope is formed along air discharge duct width direction in air discharge duct both sides, further had
Conducive to the discharge of air.
Further, the gradient on air discharge duct both sides inclined-plane is preferably 2% ~ 10%.
Further, air discharge duct cross section is down big up small trapezoidal or inverted U-shaped.
The utility model has following advantages and effect compared with prior art：After air discharge duct is arranged in piece top surface, increase
The passing away of air in splicing seams filling process greatly reduces residual bubble by the reasonable layout of air discharge duct, improves and fills
Slurry seam compactness, reduces the adverse effect to bridge structure.

Specific implementation mode
The following describes the utility model in further detail with reference to the accompanying drawings.
Figure includes air discharge duct 1, grout pipe 2, grouting bucket 3, steel cushion block 5, high-strength grout 6, annular steel form 7, sealing
Pad 8, exhaust grout outlet 9, lower pier stud 13, upper pier stud 14.
The exhaust structure as shown, a kind of precast assembly bridge pier modular level splicing seams are in the milk, the bridge pier component include
Splicing seams are formed between the correspondence Mosaic face of upper component and lower member, upper component and lower member, it is characterised in that on
One or more air discharge duct is reserved on the Mosaic face of portion's component, the air discharge duct highest point is connected to the external of upper component, makes
The slow rising with slurries top surface in grouting is obtained, the air in splicing seams is gradually discharged along air discharge duct, grouting seam is reached
Closely knit purpose.
Fig. 1 ~ 5 are specific embodiment of the utility model, and wherein upper component is upper pier stud 14, and lower member is lower pier stud
13.Form splicing seams between the bottom surface of upper pier stud and the top surface of lower pier stud, the top surface of the bottom surface of upper pier stud and lower pier stud is to correspond to
Mosaic face.It is equipped with steel cushion block 5 between upper pier stud and lower pier stud, annular punching block is set on the outside of upper pier stud and lower pier stud junction
Plate 7 sets gasket 8, grout pipe 8, institute is equipped in lower pier stud 13 between the annular steel form 7 and upper pier stud 14 and lower pier stud 13
The one end for stating grout pipe extends at lower pier stud splicing seams, and the other end is then connect with the grouting bucket on the outside of lower pier stud.
