Description
Technical field
The utility model is related to a kind of pre-buried slip casting structure for preventing bumping at bridge-head.
Background technology
Problem of bumping at bridge-head is always one of problem of puzzlement municipal administration engineers and technicians, it has also become high-grade highway
Common quality defect.Bridge and roadbed, the composition material on road surface, rigidity, intensity, swell-shrink characteristic etc. have differences, and end of the bridge junction
Easily concentrated stress is formed during stress.Under vehicular load, dead load, effect of natural environment, it is heavy that bridge occurs simultaneously with road
Drop, but both settling amount has very big difference, the settling amount of road much larger than bridge settling amount (sedimentation difference is generally 10~
30cm, the even more than 60cm having), faulting of slab ends is formed, cause that bumping at bridge-head occurs during driving.Road settlement is main by back filling behind abutment
Compactness is inadequate, the sedimentation of roadbed foundation is caused.The harm of bumping at bridge-head is mainly shown as：Influence traffic safety, reduction row
The disease of vehicle speed, influence car operation expense and acceleration bridge and road surface, the influence on system operation to road and bridge is very big.It is traditional anti-
Attacking reinforcing maintenance will be carried out in the case where suspending traffic, and the normal of influence road is used.

The distance between be 0.8m-1.0m.
The utility model is provided with the 3rd gate spool in side slope portion, and the distance between the 3rd gate spool and abutment are
The distance between 1.5m-2.0m, two described 3rd gate spools are 1.5m-2.0m.
First gate spool described in the utility model includes outer tube and being nested with the inner tube in outer tube, in the outer tube and
Plug hole is provided with the side wall of inner tube, two in axial direction adjacent plug holes are in 90 ° of settings.
Be provided with the second plug hole on the side wall of the second gate spool described in the utility model, in axial direction two it is adjacent
The plug hole is in 90 ° of settings.
One end of 3rd gate spool described in the utility model is tapered, and is provided with the side wall of the 3rd gate spool
Three plug holes, in axial direction two adjacent plug holes are in 90 ° of settings.
Good effect of the present utility model is：The first gate spool for being arranged on base course bottom can hold in road surface gene basis
Carry when power is not enough settled to slip casting is carried out in roadbed, improve foundation bearing capacity, the second gate spool can be on road surface because of platform
To slip casting in roadbed when back of the body degree of being backfilling and compacted not enough is settled, the compaction of back filling behind abutment is improved, due to first
Gate spool and the second gate spool are embedded in abutment changeover portion, and generation problem is can directly inside slip casting, it is not necessary to suspends traffic
It is capable of achieving maintenance of doing over again.Spacing between first gate spool and the spacing between abutment can be effectively ensured in slip casting
Slip casting is uniform, it is ensured that grouting quality.Spacing between the second gate spool and spacing between abutment is same can effectively protect
Card slip casting is uniform, and quality is good.The 3rd gate spool being arranged at side slope can be when there is horizontal sliding in roadbed substrate to roadbed
Interior slip casting, prevents it from the phenomenon of horizontal sliding occur.
