Abstract

The utility model provides a multiple point combined sedimentation observing device, which comprises an anchoring plate, a reference tube and a sedimentation measurement head, wherein the sedimentation measurement head comprises a connecting tube in rigid connection with the reference tube, a movable sleeving tube installed outside the connecting tube and a sedimentation plate in combined connection with the movable sleeving tube. A displacement transducer is installed in the movable sleeving tube, a flexible protective tube arranged outside the reference tube, the connecting tube and the movable sleeving tube respectively enables the reference tube, the connecting tube and the movable sleeving tube to be separated from soil body so as to reduce binding of the reference tube, the connecting tube and the movable sleeving tube to the surrounding body soil. The multiple point combined sedimentation observing device can conveniently control the embedding position of the sedimentation head and avoid appearance of a large thickness cushion layer under the anchoring plate of the sedimentation measurement head through combined design of the sedimentation measurement head, thereby improving the measurement precision of the device. The precision of the measurement precision of devices is improved by adding the flexible protective tube to reduce binding of the reference tube to the surrounding soil body.

Description

A kind of multiple spot combined type settlement observer
Technical field
The utility model relates to a kind of settlement observer based on displacement transducer, relates in particular to a kind of multiple spot combined type settlement observer, mainly is applicable to the sedimentation and deformation observation of engineerings such as roadbed, tunnel, dam, can carry out multi-measuring point, delaminating deposition observation.
Background technology
At present, more based on the instrument of displacement sensor sedimentation and deformation, like electric measuring type settlement plate, single point settlement gage, multiple spot settlement gauge etc.The test philosophy of this quasi-instrument is roughly the same, all is the sedimentation of responding to, measure relative datum point through the displacement transducer that is installed in the measuring point place, and instrument is made up of members such as anchor plate, prover pipe, sedimentation gauge head, displacement transducer and cables basically.Often there is the deficiency of following three aspects in existing instrument:
1, there is effect of contraction in prover pipe to the surrounding soil sedimentation and deformation, and this effect of contraction causes soil body sedimentation and deformation less than normal, especially in fill stratums such as roadbed, should act on more obvious;
2, the prover pipe of instrument, sedimentation gauge head are the finished product accessory; Adopt high strength rigid materials such as steel pipe, steel plate to process; Through screwed connection, such finished product member causes instrument construction to bury that the sedimentation gauge head is difficult to be controlled at the desired position of design in the process underground;
3, bury underground in the process, need insert certain thickness bed course under the sedimentation gauge head anchor plate, and the bed course compactness is difficult to accomplish with bottom soil body unanimity, if cushion thickness more usually can cause the sedimentation test results distortion.
Because of the existence of above three aspect problems, make and often follow the calibration accuracy of shop experiment to have certain difference based on the on-the-spot test precision of displacement sensor sedimentation and deformation instrument at present, even can't satisfy the needs of engineering sedimentation and deformation observation.
The utility model content
The purpose of the utility model is to the problem that exists in the prior art, and a kind of multiple spot combined type settlement observer is provided.
The multiple spot combined type settlement observer of the utility model comprises anchor plate, prover pipe, sedimentation gauge head.Said sedimentation gauge head comprise with the rigidly connected connecting pipe of prover pipe, be installed in the outer moving casing of connecting pipe, with the rigidly connected settlement plate of moving casing; In the said moving casing displacement transducer is installed; One end of this displacement transducer is fixed on the moving casing, and the other end is fixed on the connecting pipe.
Said settlement plate carries out combined type with moving casing and is connected; Said prover pipe, connecting pipe and moving casing are provided with flexible pillar outward, and itself and the soil body are isolated, to reduce the constraint to surrounding soil of prover pipe, connecting pipe, moving casing.
Said settlement plate carries out combined type with moving casing through nut, bolt and is connected.
Be provided with gag lever post in the said moving casing, an end of this gag lever post is fixed in moving casing, and the other end is inserted in the snap ring that is arranged on the connecting pipe, rotates around connecting pipe to prevent the sedimentation gauge head.
The two ends of said moving casing are provided with plug, get into moving casing to prevent the soil body, and when the sedimentation gauge head slides, play certain lubrication.
Said displacement transducer can be connected with wireless transport module through cable, so that carry out wireless transmission group network observation and data analysis.
During use, bury anchor plate and prover pipe through boring or pre-buried mode underground in datum, anchor plate and prover pipe adopt and are rigidly connected, and prover pipe is buried underground to measuring point, and the sedimentation gauge head is installed at the measuring point place.After the sedimentation gauge head was buried completion underground, its settlement plate embedded the soil body at measuring point place, during soil body sedimentation and deformation; Deform in same pace takes place in settlement plate thereupon; At this moment, displacement transducer just energy measure settlement plate and moving casing sedimentation value, the i.e. settling amount of the measuring point place soil body with respect to connecting pipe.
The utility model has the following advantages relatively:
1, through the sedimentation gauge head being carried out the combined type design, can conveniently control its burial place, and avoid the appearance of big thickness bed course under the sedimentation gauge head anchor plate, thus the measuring accuracy of raising device.
2, through setting up flexible pillar to reduce the constraint of prover pipe, to improve the measuring accuracy of device to surrounding soil.
3, adopt double mode working mechanism; When constructions such as roadbed, tunnel, dam, can adopt manual mode, directly through the readout instrument reading of data; After the engineering completion is come into operation; Automatic mode be can select for use,, wireless transmission group network observation and data analysis just can be carried out through increasing a wireless transport module.
