Description
Technical field
The present invention is mainly concerned with technology and the instrument field that detects foundation settlement, refers in particular to a kind of single point settlement gage.
Background technology
The roadbed of basis, particularly high-speed railway, speedway when their outer load effects are descended or its inner formation condition changes, can produce certain sedimentation, the comfortableness of too much sedimentation meeting influence driving, even jeopardize traffic safety.Therefore, the settling amount on roadbed, road surface must be limited in certain scope, must take appropriate measures when transfiniting and handle.Existing settlement observation method is that a circular sedimentation pipe is anchored to basement rock, and magnet ring is enclosed within the sedimentation pipe periphery, is embedded in observation aspect position.When immerge, magnet ring can sink and sedimentation pipe can not sink synchronously with the basis, and magnet ring is then along axially down slippage of sedimentation pipe, by relative slippage between measuring and calculating magnet ring and the sedimentation pipe, realizes the measurement purpose.But there is following shortcoming in this method: 1, the sedimentation pipe burial place can not carry out compaction treatment, and roadbed need carry out compaction treatment usually, if the measuring point is not with the road surface compacting, will cause measured value and actual value inconsistent, caused certain measuring errors, simultaneously also influence construction; Must from the hole of sedimentation pipe, put down the just position of energy measurement magnet ring of magnetic probe when 2, detecting, thus can only manual measurement, and have shortcomings such as low precision, workload is big, efficient is low; 3, can not measure in real time in the driving, can't carry out the long-time running monitoring.
Summary of the invention
The problem to be solved in the present invention just is: at the technical problem that prior art exists, the invention provides a kind of simple and compact for structure, with low cost, can measure automatically quickly and accurately, the single point settlement gage of long term monitoring.
For solving the problems of the technologies described above, the solution that the present invention proposes is: a kind of single point settlement gage, it is characterized in that: it comprises settlement plate, electrical measurement displacement transducer, measuring staff, anchor head and bottom anchor head, one end of described electrical measurement displacement transducer links to each other with the settlement plate bottom, the other end links to each other with anchor head by measuring staff, and the other end of described anchor head links to each other with the bottom anchor head by extension bar.
Described electrical measurement displacement transducer comprises sensor cylindrical shell, pick-up piston bar and sensor conductor, described pick-up piston bar is inserted in the sensor cylindrical shell and can endwisely slipping along the sensor cylindrical shell, the pick-up piston bar links to each other with measuring staff, and the sensor cylindrical shell links to each other with controlling organization by sensor conductor.
The outside of described measuring staff is arranged with metal hose.
The both sides of described anchor head are equiped with two knees, and two install depression bar is inserted on the knee.
Compared with prior art, advantage of the present invention just is: single point settlement gage of the present invention adopts integral body to bury underground, and lead is drawn from the settlement plate side, can not influence the compacting construction on road surface, thereby guarantee that measured value is consistent with actual value, and the driving process also can be measured.The present invention adopts the electrical measurement displacement transducer, can be quickly and accurately directly measures sedimentation in real time, but remote transmission also realizes measuring automatically and long-term observation.

The specific embodiment
Below with reference to the drawings and specific embodiments the present invention is described in further details.
As shown in Figure 1, single point settlement gage of the present invention, it comprises settlement plate 1, electrical measurement displacement transducer 2, measuring staff 5, anchor head 7 and bottom anchor head 10, one end of electrical measurement displacement transducer 2 links to each other with settlement plate 1 bottom, the other end links to each other with anchor head 7 by measuring staff 5, the outside of measuring staff 5 is arranged with metal hose 6, and the other end of anchor head 7 links to each other with bottom anchor head 10 with straight coupling 9 by extension bar 8.Single point settlement gage integral body of the present invention is embedded in below the road surface, and bottom anchor head 10 anchors on the basement rock, and settlement plate 1 is circular dull and stereotyped, and its center is provided with screwed hole, uniform all around fan-shaped pylone and two circular holes, and its diameter is greater than burying the aperture underground.Metal hose 6 is a kind of tensible elastic tube, by metal hose nipple 14 electrical measurement displacement transducer 2 and anchor head 7 is fused, and metal hose 6 is pulled to and assembles when the longest, and its shortening amount satisfies range ability.Extension bar 8 is a pipe, and its upper/lower terminal is equipped with screw thread, be used for anchor head 7, straight coupling 9, bottom anchor head 10 between connect.The upper end of extension bar 8 links to each other with anchor head 7, and the lower end can fathom as required to add to grow to bottom anchor head 10 with a plurality of straight couplings 9 and link to each other.
Electrical measurement displacement transducer 2 comprises sensor cylindrical shell 3, pick-up piston bar 4 and sensor conductor 11, pick-up piston bar 4 is inserted in the sensor cylindrical shell 3 and can endwisely slipping along sensor cylindrical shell 3, sensor cylindrical shell 3 links to each other with system equipment with test instrumentation in the controlling organization by sensor conductor 11, pick-up piston bar 4 links to each other with measuring staff 5 by measuring staff joint 12, and sensor conductor 11 is drawn from the side of settlement plate 1.Pick-up piston bar 4 is the magnetic conductive metal bar, sensor cylindrical shell 3 built-in inductance coil and data processing circuits, the slip of pick-up piston bar 4 can cause that the inductance value of inductance coil changes with skidding distance, this signal sends test instrumentation and system equipment to through sensor conductor 11, watches for the observation personnel.Electrical measurement displacement transducer 2 connects with the screwed hole of settlement plate 1 by the external screw thread that its upper end is provided with, and measuring staff 5 lower ends are provided with internal thread and connect with anchor head 7, and the lower end of electrical measurement displacement transducer 2 and anchor head 7 are provided with outer screw tap gas thread, connects metal hose 6 in the middle of it.In the present embodiment, anchor head 7 connects with measuring staff 5 by its outer straight thread in upper end, is connected with metal hose 6 by its outer taper pipe thread in upper end, and is connected with extension bar 8 by its lower end external screw thread; The both sides of anchor head 7 are welded with two knees, and during installation, two install depression bar 13 inserts on the knee, and just takes out at the intact rear of installation.
Operating principle: single point settlement gage of the present invention adopts integral body to bury underground, and bottom anchor head 10 is anchored on the bottom basement rock by grouting, and settlement plate 1 is installed on the tested base surface and (is positioned at the aperture), and sensor conductor 11 is drawn from the side.When immerge, settlement plate 1 sinks with the basis, settling amount between settlement plate 1 and the bottom anchor head 10 just directly equals relative skidding distance between sensor cylindrical shell 3 and the pick-up piston bar 4, because the inductance value of the inductance coil of establishing in the sensor cylindrical shell 3 is relevant with the insertion length of pick-up piston bar 4 that is the magnetic conductive metal bar, to cause the variation of winding inductance quantity, through data processing circuit, be connected with system equipment with measuring apparatus by sensor conductor 11 as controlling organization, can obtain sedimentation value in real time, realize the settlement observation purpose.
