Description
Technical field
The utility model relates to a kind of road settlement measuring devices, supervise particularly for constructing with the road settlement of operation stage
Survey field.
Background technique
Requirement of the modern transportation to sedimentation is particularly stringent, does not require nothing more than roadbed reclamation, to settlement after construction, differential settlement
And surface evenness etc. has different requirements, otherwise due comfort is not achieved in engineering, causes late maintenance cost excessively high
Problem.Currently, since weak soil has water content is high, compressibility is big, poor permeability, void ratio is big, intensity is low and sensitivity is high etc.
Feature builds high-grade highway on soft soil foundation and still has many problems: first, the sedimentation and relative settlement of soft soil foundation
Excessive problem；Second, the stable problem occurred during roadbed filling.
Existing settlement measurement generally has more make although this method have been relatively mature using sedimentation plate and level
With experience, level itself is also able to satisfy the required precision of engineering.However since sedimentation mark post is higher than roadbed ground, road is applied
There is interference in work.Mark post is vertical to will affect filling for embankment there, around soil be difficult to be compacted, influence the quality banketed, and
Construction is easily destroyed sedimentation mark.In addition, with the placement in layers of embankment, it is desirable that also merogenesis connects height to mark post, not only troublesome in poeration,
Influence accuracy of observation.Set up that level is time-consuming, and especially the depth of fill is higher when measurement every time, turn station it is more when, need more
Secondary erection, measurement efficiency reduce.
Summary of the invention
It is simple that problem to be solved in the utility model provides a kind of structure aiming above insufficient, meets descent precision
It is required that road settlement observation device.Its technical solution is as follows:
It includes measurement Markov bottle and sedimentation sensing bottle, and sedimentation sensing bottle is embedded in roadbed bottom measurement position, measures horse
Family name's bottle is connected with sedimentation sensing bottle by connecting pipe, and measurement Markov bottle is provided with measurement liquid, is pushed up inside measurement Markov bottle
End installation laser distance measuring device, places fixing pipe in sedimentation sensing bottle.
The measurement Markov bottle is located at by roadbed.
The laser distance measuring device accuracy is no more than 1mm.
The sedimentation sensing bottle is style of opening, and air pressure inside is consistent with atmospheric pressure.
Compared with prior art, the utility model has the beneficial effect that
1, the utility model is of simple structure and low cost, easily operated at the scene, and automatic measurement does not influence road construction,
It is not easily susceptible to destroy.
2, the utility model is using Markov bottle is inverted as the plane of reference, and in the case that guaranteed water level changes, reference pressure is not
It changes, meets descent precision requirement.
3, the utility model uses laser ranging, is not influenced by temperature and humidity, improves measurement accuracy.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Specific embodiment
Referring to Fig. 1, the utility model includes measurement Markov bottle 21 and sedimentation sensing bottle 25, and sedimentation sensing bottle 25 is embedded in
1 bottom measurement position of roadbed, measurement Markov bottle 21 and sedimentation sensing bottle 25 are connected by connecting pipe 24；It measures in Markov bottle 21
Equipped with measurement liquid 22, laser distance measuring device 23 is installed in measurement 21 inner tip of Markov bottle, in sedimentation sensing bottle 25
Fixing pipe 26 is placed, to fix the elevation of bottom water level, top SEA LEVEL VARIATION is made to will not influence the measurement accuracy of sedimentation.
The measurement Markov bottle 21 is located at the position not settled by roadbed, apart from road embankment 5-50m, provides stabilization
Head reference, as a preference, the measurement Markov bottle 21 is apart from road embankment 10m.
23 measurement accuracy of laser distance measuring device is no more than 1mm, as a preference, the laser distance is surveyed
Amount 23 measurement accuracy of device is 1mm.
The sedimentation sensing bottle 25 is style of opening, and non-tight structure is connected with external atmosphere pressure, air pressure inside and atmospheric pressure
Unanimously.
The utility model work progress the following steps are included:
1. surveying and locating determines observation device burial place；
2. burying sedimentation sensing bottle 25 before roadbed 1 is constructed, the pipeline 24 is connected；
3. in pipeline top backfill, fixed pipelines are reserving enough pipelines at the sedimentation sensing bottle 25, just
In 25 free settling of sedimentation sensing bottle；
4. burying the measurement Markov bottle 21, connecting pipeline, topped up with water by roadbed；
5. 21 internal liquid of measurement Markov bottle is measured every 10min, until water level no longer changes, as initial water level
Highly；
6. constructing to roadbed, liquid in the measurement Markov bottle 21 is measured by construction requirement frequency.If
Subgrade settlement, sedimentation sensing bottle 25 settle therewith, and the measurement liquid (such as water) 22 measured in Markov bottle 21 can pass through connecting tube
Road 24 flows into sedimentation sensing bottle 25, is measured by laser distance measuring device 23 and measures liquid change in the measurement Markov bottle 21
Change can inverse go out settle sensing bottle 25 sedimentation.
