Abstract
The utility model discloses an embankment section settlement monitoring device. The device comprises a metal rod of which one end is buried in a subgrade and the other end is provided with a displacement sensor, wherein a testing wire is arranged on the displacement sensor; the device also comprises a hard plastic pipe of which the two ends are both provided with a measuring tank; one end of the testing wire is arranged inside one measuring tank; the hard plastic pipe is fixedly arranged on the displacement sensor; embankment filled soil is arranged on the hard plastic pipe. The structure is completed before the construction of the embankment filled soil, no influences are caused to the rolling of the embankment filled soil, and the construction quality of the embankment is liable to be guaranteed. The embankment sediment deformation data of the overall construction process can be acquired, and the sediment size and development tendency of the embankment can be fully reflected. The device has the advantages of easy construction, high measurement precision, convenient test and good durability.
Description
Technical field
The utility model relates to subgrade deformation monitoring technical field, is specially a kind of embankment Settlement Profiler monitoring device.
Background technology
Development along with China Express Railway and expressway construction, this also roadbed engineering distortion sedimentation higher requirement has been proposed, especially for the high-speed railway subgrade engineering that adopts non-fragment orbit technology, the control technique of settlement after construction standard is only 15mm, therefore need in work progress, strengthen settlement monitoring.The impact that changed by topographic relief and zone thickness, each position sedimentation of embankment is often inconsistent, the following several modes of the general employing of embankment transverse section settlement monitoring: 1. in transverse section direction, bury a plurality of observation stakes underground; 2. in transverse section direction, bury a plurality of settlement plates underground; 3. bury Settlement Profiler pipe underground.But all there is following shortcoming in above several modes: observation stake could be constructed after embankment completes, more difficult size and the overall trend that reacts all sidedly Embankment Subsidence.Settlement plate needs constantly to connect height in embankment process, and construction technology is comparatively loaded down with trivial details, and near settlement plate, can not use big machinery to roll, and embankment filled soil construction quality is vulnerable to impact.Settlement Profiler pipe can be constructed before embankment, can obtain comparatively comprehensively Embankment Subsidence data, the method must arrange reference point, mainly take at present observation stake to be set as reference point at the nozzle position of section pipe, but the measuring accuracy of observation stake is lower, generally lower than 1mm, and be easy to be subject to the impact of surrounding environment, limited promoting the use of of the method.
Utility model content
The purpose of this utility model is that the embankment Settlement Profiler monitoring device of the high and good endurance of a kind of measuring accuracy is provided in order to overcome above-mentioned deficiency.
The utility model comprises that one end is embedded in the Metallic rod that ground, the other end are provided with displacement transducer, described displacement transducer is provided with test lead, also comprise that two ends are equipped with the plastic conduit of measuring cell, one end of described test lead is positioned at measuring cell, described plastic conduit is installed on displacement transducer, and described plastic conduit is provided with embankment filled soil.
Between described plastic conduit and displacement transducer, be provided with fixed disc.
Described displacement transducer is positioned at end or the centre of plastic conduit.
Described measuring cell is provided with cover plate.
The utlity model has following advantage:
1, because this structure completes before embankment filled soil construction, so can not affect rolling of embankment filled soil, embankments construction quality is easy to be guaranteed.
2, because Metallic rod is provided with displacement transducer, displacement transducer is provided with test lead, one end of test lead is positioned at measuring cell, so this structure can be obtained For Embankment Settlements data in whole work progress, and measuring accuracy is high, can reflect sedimentation size and the development trend of roadbed comprehensively.
3, because this structure is directly embedded on ground, so there is the construction of being easy to, convenient test and good endurance.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with drawings and Examples, further illustrate the utility model.
Embodiment: the utility model comprises that one end is embedded in ground, the other end is provided with the Metallic rod 2 of displacement transducer 1, described displacement transducer 1 is provided with test lead 3, also comprise that two ends are equipped with the plastic conduit 5 of measuring cell 4, one end of described test lead 3 is positioned at measuring cell 4, described plastic conduit 5 is installed on displacement transducer 1, described plastic conduit 5 is provided with embankment filled soil 6, between described plastic conduit 5 and displacement transducer 1, be provided with fixed disc 7, described fixed disc 7 centers generally adopt metal hollow structure, described displacement transducer 1 is positioned at end or the centre of plastic conduit 5, described measuring cell 4 is provided with cover plate 8.
Wherein, the parts such as fixed disc 7, displacement transducer 1, Metallic rod 2 and test lead 3 form single point settlement gage; Plastic conduit 5 is with cross recess, and as Settlement Profiler pipe.Single point settlement gage is arranged at Settlement Profiler tube end or centre position, and colligation is between the two fixed together, thereby single point settlement gage can be used as the reference point of Settlement Profiler pipe.Measuring cell 4 and cover plate 8 adopts brickwork construction conventionally, and space is provided for the protection of Settlement Profiler pipe and while testing for Section type settlement instrument.Settlement Profiler pipe is tested by Section type settlement instrument, at interval of 1～3m, reads numerical value one time.
Sequence of construction and using method are as follows: after 1. ground is finished dealing with, the Metallic rod 2 of single point settlement gage is buried in boring underground, and Settlement Profiler pipe is buried in grooving underground, and plastic conduit 5 and fixed disc 7 colligations are fixed together, and records corresponding position; 2. placement in layers embankment; 3. in a period of time after the neutralization of embankment process has been filled, the settling amount of test single point settlement gage, and as the reference point of relevant position Settlement Profiler pipe, adopt the sedimentation of Section type settlement instrument test section pipe, calculate the settling amount of embankment transverse section.
Above-described embodiment is preferably embodiment of the utility model; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify; all should be equivalent substitute mode, within being included in protection domain of the present utility model.
