Abstract
The invention specifically provides a method and a device for observing layered settlement of high fill earth, and aims at solving the problem that the height settlement data of the existing high fill earth cannot be observed and so that the potential risk cannot be early found out. The method comprises the steps of a, fixing a cross channel steel frame of which the center is fixed with a reinforcing steel bar body, observing the number and record; b, backfilling and rolling by layers, and recording the settlement value; c, continuously connecting when the backfilled earth reaches the top end of the reinforcing steel bar body; d, arranging the cross channel steel frame I when backfilling to reach the height of a second observing point, wherein a steel pipe body is fixed in the center of the cross channel steel frame I; recording the observing number; e, continuously backfilling rolling by layering, and recording the settlement value of each observing point; f, continuously connecting the steel pipe body when the backfilled earth reaches the top end of the steel pipe body; g, repeating steps from d to f when the earth is backfilled to reach the height of a third observing point until the backfilling and rolling are done. With the adoption of the method and the device, the layered observing of a plurality of observing points in vertical direction during backfilling can be achieved.
Description
Technical field
The present invention relates to building operation settlement observation technology, be specially a kind of high roadbed soil body layered settlement observation method and device.
Background technology
Usually larger sedimentation can be there is in construction work high roadbed place; and ubiquity settling process is longer and the problem such as non-uniform settling; larger on the safety and stability impact of various engineering structure; therefore; to the sedimentation of engineering structure foundation soil body, especially delaminating deposition feature is carried out monitoring and is had very important significance.
The method of current monitoring foundation soil body delaminating deposition, after high roadbed place has backfilled, at ground, more shallow place arranges observation station, only can observe the settling data on backfill groundwork top, cannot observe the settling data of height each in backfilling process, and then the compaction rate of the high roadbed soil body cannot be ensured, stability is poor, there is potential safety hazard.
Summary of the invention
The present invention cannot observe to its each height settling data the problem causing the potential safety hazard existed not find in advance to solve the existing high roadbed soil body, provides a kind of high roadbed soil body layered settlement observation method and device.
The present invention adopts following technical scheme to realize: high roadbed soil body layered settlement observation method, adopt following steps: a, backfill initial absolute altitude place install the first step observation station time, temporary fixed cross recess steelframe, the center of cross recess steelframe is fixed with the reinforcing bar body vertically placed, by reinforcing bar body top with extraneous with reference to chi observed reading and record; B, carry out back-filling in layers and roll, often backfill one deck, all observed by reinforcing bar bodies top, the settling amount of record first step observation station; C, when the floor height of backfill soil is close to reinforcing bar body top, at reinforcing bar body top continued access reinforcing bar body, the reinforcing bar body top at top is positioned at above back fill course all the time; When d, backfill reach the height need installing second step observation station, place cross recess steelframe I, the center of cross recess steelframe I is fixed with the steel pipe body be enclosed within reinforcing bar body, the observed reading on record steel pipe body top; E, continuation back-filling in layers roll, and observed, record the settling amount of each observation station by the steel pipe body top at reinforcing bar body top and top; F, when the floor height of backfill soil is close to steel pipe body top, at steel pipe body top continued access steel pipe body, the steel pipe body top at top is positioned at above back fill course all the time; When g, backfill reach the height need installing the 3rd step observation station, rolled to backfill by steps d-f repeatable operation, in backfilling process, the reinforcing bar body top at top and the steel pipe body top of its outside top are in step condition all the time.
During operation, according to the number of the area of plane determination settlement observation point of embankment, according to the step number of backfill thickness determination settlement observation point, adopt the method can obtain the data of backfilling process and layered settlement observation, and tracking observation can also be continued in the completed.
High roadbed soil body layered settlement observation method device, comprise the cross recess steelframe being arranged on and backfilling initial absolute altitude place, the center of cross recess steelframe is fixed with the reinforcing bar be vertically formed by connecting by some reinforcing bar bodies, reinforcing bar arranged outside has the steel pipe of some mutual sockets, and every root steel pipe is all vertically be formed by connecting by some steel pipe bodies, be fixed with the cross recess steelframe I arranged from down to up bottom steel pipe from inside to outside successively, and all cross recess steelframe I are all positioned at above cross recess steelframe.
Processing step of the present invention is rationally reliable, achieve the observation of vertical multiple observation station in backfilling process, and tracking observation can be continued in the completed, effectively ensure that the stability of the high roadbed soil body, stop potential safety hazard, there is simple, the easy to operate and advantage that cost is low of technique simultaneously.
