The roadbed cross-section sedimentation observation device comprises a section settlement meter, a section settlement tube and a traction rope, wherein the traction rope pulls the section settlement meter to move in the section settlement tube; positioning magnetic rings are distributed on the periphery of the section settlement tube at intervals; and the section settlement meter is provided with a magnetic field sensing buzzer. One end of the section settlement tube is connected with a steel flexible pipe; and one end of the traction rope penetrates into the section settlement tube and out of the steel flexible tube. The positioning magnetic rings and the magnetic field sensing buzzer are arranged, and the positioning magnetic rings and the magnetic field sensing buzzer are combined to position settlement observation points, so that the observation precision is greatly improved; the steel flexible tube is used, so the traction rope can be turned back, and two ends of the traction rope are positioned on the same side of the roadbed; operators can operate the device on one side of the roadbed during measurement; and the convenience for observation operation is improved.
Description
Technical field
The utility model relates to a kind of construction detecting instrument technical field, specifically is a kind of device that the transversal section of roadbed is carried out settlement observation.
Background technology
Subgrade settlement detects generally adopts the method for burying settlement plate underground, but is subject to the destruction of roadbed filling construction machinery and causes the incomplete or out of true of data.Cross-sectional sedimentation detector has buries conveniently, is not subjected to that the roadbed filling construction is disturbed, the characteristics of sectional observation entirely underground, widespread use in engineering practice at present, and especially widen in the little engineering of the subgrade construction scope of operation such as engineering application at roadbed wider.Section sedimentometer commonly used at present mainly contains clinoscope and section sedimentation test pressure meter, the tiltmeter cardinal principle is to utilize the angle between surface level and the vertical plane to come computed range, just can obtain the settling amount of each measuring point by adding up of vertical plane distance; Section sedimentation test pressure meter is a principle of utilizing linker, according to the convert settling amount of each measuring point of the water pressure difference between aperture and measuring point.Cross-sectional sedimentation detection method commonly used is to dig a lateral trench on the roadbed top layer, the plastics sedimentation pipe that will have excellent toughness is embedded in the groove, spur the section sedimentometer with the lead-in wire that is preset in the sedimentation pipe during test, detect data every 0.5m or 1.0m, detect data for twice and subtract each other and just can obtain the settling amount in twice observation time of certain o'clock on the subgrade cross section.
A large amount of engineering practices show, conventional cross-sectional settlement observation method, because the location point of twice observation in front and back cannot say for sure that card is at same position, and roadbed subsidence rate in the horizontal is also inequality, often precision is on the low side to observe the data that obtain like this, especially under subgrade settlement speed situation less than normal, the abnormal occurrence of data bounce-back often appears.In addition, conventional cross-sectional sedimentation detection method needs the testing staff at the moving lead-in wire of roadbed one layback, also testing staff's reading and record will be arranged at the roadbed opposite side simultaneously, when roadbed filling is higher, cooperation between the testing staff also will lean on intercom to realize that it is more loaded down with trivial details to operate.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model purpose is to provide that a kind of accuracy of observation is higher, the cross-sectional settlement observer of roadbed that has the magnet ring location of more convenient operation.
To achieve these goals, the technical solution adopted in the utility model is:
The cross-sectional settlement observer of roadbed that has the magnet ring location, include section sedimentometer, section sedimentation pipe, traction rope, wherein, traction rope pulling section sedimentometer moves in the section sedimentation pipe, the periphery of described section sedimentation pipe is intervally distributed with the location magnet ring, and described section sedimentometer is provided with the magnetic field induction hummer.
On the described section sedimentation pipe and be positioned at the location magnet ring two ends be provided with spacing ring, described location magnet ring is fixed on the section sedimentation pipe by spacing ring.
One end of described section sedimentation pipe is connected with the steel flexible pipe, and an end of described traction rope penetrates from the section sedimentation pipe, pass from the steel flexible pipe, and the traction rope traversing through end that penetrates end and steel flexible pipe of section sedimentation pipe traction rope is positioned at the homonymy of institute's observation roadbed.
The beneficial effects of the utility model: owing to set up location magnet ring and magnetic field induction hummer, being used in combination of location magnet ring and magnetic field induction hummer can be located settlement observation point, thereby improved the precision of observation greatly; Owing to utilize the steel flexible pipe, traction rope can be turned back, make the two ends of traction rope be positioned at the same side of roadbed, operating personnel can improve the convenience of observation operation in the side operation of roadbed during test.
