Abstract
The utility model discloses a subgrade settlement detection system, which comprises a liquid container, a connecting pipe and a detection pipe and also a general packet radio service (GPRS) communication module, wherein the liquid container is communicated with the detection pipe through the connecting pipe; the top end of the detection pipe is closed and is provided with a pressure sensor; and the pressure sensor is connected with the GPRS communication module. The subgrade settlement detection system has the beneficial effects that the subgrade settlement detection system has the advantages of realizing long-range measurement, along with high measurement precision, high stability and low long-term operation and maintenance workload, and the like.
Description
Technical field
The utility model belongs to sensor technical field, relates to a kind of roadbed settlement monitoring equipment.
Background technology
In the prior art, the subgrade settlement monitoring has several different methods, different according to how much distributions that measuring point is arranged, mainly can be divided into single-point sedimentation, delaminating deposition, transverse section sedimentation and longitudinal profile (alignment) sedimentation, can be divided into again the methods such as settlement plate method, electromagnetic type sedimentometer, native displacement meter, inclinometer pipe method, static level method, hydraulic pressure sedimentometer, fiber-optic grating sensor according to measuring method.Subgrade settlement instrument for existing communicating pipe, pressure transducer often places the bottom of monitoring point, and the precision of pressure transducer and range are proportional, range is larger, precision is lower, because existing subgrade settlement instrument pressure transducer places the bottom of communicating pipe, so the range of its monitoring is just larger, the precision of therefore measuring is just lower.In addition, because the communicating pipe container of monitoring point is uncovered, the liquid in communicating pipe volatilizees easily, and for long term monitoring, maintenance workload is larger, and the measurement data of gained is processed, and realizes remote observation.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of subgrade settlement monitoring system, and this roadbed settlement monitoring equipment accuracy of detection is high, and is easy to safeguard, and can realize remote monitoring.
For reaching above purpose, the utility model adopts following technical scheme: the subgrade settlement detection system, comprise the liquid container that is positioned over reference point, the detector tube that is positioned over tested point, it also comprises the GPRS communication module, described liquid container is communicated with detector tube by connecting pipe, described detector tube top closure and be provided with pressure transducer, described pressure transducer is connected with described GPRS communication module.
As preferably, described connecting pipe horizontal positioned, and connecting pipe is identical with the diameter of detector tube.
As preferably, described connecting pipe horizontal positioned, and the diameter of connecting pipe is less than the diameter of detector tube.
As preferably, described detector tube is 1-20 according to the quantity setting of tested point.
As preferably, the liquid of splendid attire is anti freezing solution in the described liquid container.
The beneficial effects of the utility model are: subgrade settlement monitoring system of the present utility model, have the measuring accuracy height, and good stability, the long-time running maintenance workload is little, can realize the advantages such as remote measurement.
Description of drawings
In order to be illustrated more clearly in the technical solution of the utility model, the accompanying drawing of required use was done to introduce simply during the below will describe embodiment, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model structural drawing.
Among the figure: 1. liquid, 2. liquid container, 3. connecting pipe, 4. detector tube, 5. pressure transducer, 6.GPRS communication module.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is explained in detail, in conjunction with Fig. 1, the subgrade settlement detection system, comprise liquid container 2, connecting pipe 3, detector tube 4, it also comprises GPRS communication module 6, and described liquid container 2 is communicated with described connecting pipe horizontal positioned by connecting pipe 3 with detector tube 4, and connecting pipe is identical with the diameter of detector tube, and perhaps the diameter of connecting pipe is less than the diameter of detector tube.Described detector tube 4 top closure and be provided with pressure transducer 5, described pressure transducer 5 is connected with described GPRS communication module 6.Detector tube can be 1 according to the quantity setting of tested point, also can be 2,3,4,5,10,15,18,19,20.Liquid container reference point during installation pours into antifreezing liquid, antifreezing liquid is mainly as the Transfer Medium of pressure, and can be operated under the wide temperature condition, the detector tube of adjusting place so that liquid just detector tube is full of and just touches pressure transducer, the value of regulating the tested point pressure transducer is zero, and reference point location at this moment is as initial position.When the subgrade settlement of monitoring point, the detector tube of the tested point equal height that also can sink, at this moment can form the liquid level of reference point and the top of tested point closed container and form pressure reduction, gather this pressure reduction by pressure transducer, processing can draw settling height through mathematical conversion, by the GPRS communication module this information is delivered to control terminal and monitors processing.
The above person, being preferred embodiment of the present utility model only, is not to limit practical range of the present utility model, and namely all equalizations of doing according to the utility model change and modify, be all the utility model claim scope and contain, give an example no longer one by one here.
