The present invention cannot be observed to its each height settling data leading to presence to solve the existing high roadbed soil body
A kind of problem that potential safety hazard can not find in advance, there is provided high roadbed soil body layered settlement observation method and device.
The present invention adopts the following technical scheme that realization: high roadbed soil body layered settlement observation method, is walked using following
Rapid: when first step observation station being installed at a, the initial absolute altitude of backfill, interim fixed cross U-steel frame, the center of cross U-steel frame is fixed
There is the reinforcing bar body of vertical placement, with reference to chi observed reading and recorded with the external world by reinforcing bar body top；B, it is layered back
Fill out and roll, often backfill one layer, all observed by reinforcing bar bodies top, the settling amount of record first step observation station；C, work as backfill
Floor height close to reinforcing bar body top when, in piece reinforcing bar body of reinforcing bar body top continued access, make the reinforcing bar body top at top
It is always positioned above back fill course；When d, backfill reach the height that need to install second step observation station, placement cross U-steel frame i, ten
The center of word U-steel frame i is fixed with the steel pipe body being enclosed within reinforcing bar body, the observed reading on record steel pipe body top；E, continue
Continuous back-filling in layers rolls, and is observed by the steel pipe body top at reinforcing bar body top and top, records each observation station
Settling amount；F, when the floor height of backfill is close to steel pipe body top, in piece steel pipe body of steel pipe body top continued access, make top
The steel pipe body top in portion is always positioned above back fill course；When g, backfill reach the height that need to install the 3rd step observation station, press
Step d-f repeatable operation rolls and completes to backfill, in backfilling process, the reinforcing bar body top at top and the steel pipe of its outside top
Body top is in step condition all the time.
During operation, determine the number of settlement observation point according to the area of plane of embankment, determine that sedimentation is seen according to backfill thickness
The step number of measuring point, can obtain the data of backfilling process and layered settlement observation using the method, and can also continue in the completed
Tracking observation.
High roadbed soil body layered settlement observation method device, including the cross channel-section steel being arranged at the initial absolute altitude of backfill
Frame, the center of cross U-steel frame is fixed with the reinforcing bar being vertically formed by connecting by some reinforcing bar bodies, is provided with some outside reinforcing bar
The steel pipe of mutual socket, and every steel pipe is all vertically to be formed by connecting by some steel pipe bodies, steel pipe bottom from inside to outside according to
Secondary be fixed with the cross U-steel frame i arranging from down to up, and all cross U-steel frame i are respectively positioned on above cross U-steel frame.
The process step of the invention rationally reliable it is achieved that in backfilling process vertical multiple observation stations observation, and
And tracking observation can be continued in the completed, it is effectively guaranteed the stability of the high roadbed soil body, prevented potential safety hazard, simultaneously
There is process is simple, easy to operate and low cost.
Brief description
Fig. 1 is the structural representation of the present invention.
In figure: 1- cross U-steel frame, 2- reinforcing bar body, 3- steel pipe body, 4- cross U-steel frame i, 5- straight screw sleeve.
Specific embodiment
High roadbed soil body layered settlement observation method, using following steps: install the first step at a, the initial absolute altitude of backfill and see
During measuring point, interim fixed cross U-steel frame 1, the center of cross U-steel frame 1 is fixed with the reinforcing bar body 2 of vertical placement, by steel
Muscle body 2 top and is recorded with reference to chi observed reading with the external world；B, carry out back-filling in layers and roll, often backfill one layer, all by steel
Muscle body 2 top is observed, the settling amount of record first step observation station；C, when the floor height of backfill is close to reinforcing bar body 2 top,
In reinforcing bar body piece reinforcing bar body 2 of 2 top continued access, reinforcing bar body 2 top at top is made to be always positioned above back fill course；d、
