Description
Technical field
The present invention relates to engineering monitoring technical field, especially deep soil movement monitoring technical field.
Background technology
Deep soil movement monitoring refers to utilize instrument and equipment monitoring the earth inner horizontal motion, such as unsteady side slope or shoveling
Radio direction finding around engineering, Soft Ground, dykes and dams, core wall stability, the deviation for the setting that drills, the soil body caused by piling
Displacement, and backfill fill and the soil body depression of underground engineering, it can also be used to coastal, riverside gravity storage object field soil layer change
Deng.
Instrument and equipment
Inclinometer.General inclinometer is made up of probe, cable, data collecting instrument (readout instrument).The sensor pattern of probe is watched
A variety of patterns such as accelerometer formula, resistance-strain chip, steel chord type, differential resistance type are taken, most commonly used at present is that servo adds
Speed mode.There is the CX series that the Ministry of Aerospace Industry 33 is produced the country, and there are the digital incliometer of SINCO companies of the U.S. in foreign countries, Switzerland
PRIVEC etc..
Inwall has the inclinometer pipe of guide groove, is made up of inclinometer pipe, connecting tube, base, lid.Inclinometer pipe is with polyvinyl chloride, ABS
The materials such as plastics, aluminium alloy are made, and 90 degree of four guide grooves are mutually in pipe, and domestic plastics deviational survey pipe size is mostly：Internal diameter Φ
58mm, footpath Φ 70mm, length divide 2m, tri- kinds of 3m, 4m.The pvc tube that plastic union pipe is sold using in the market more
It is made, also can use soft universal contact to be connected.The size of connecting tube is internal diameter Φ 70mm, external diameter Φ 82mm, length point 300,
Two kinds of 400mm.There are sliding groove each 4 or only one end milling sliding groove 4 in the both ends milling of tube wall, each groove is separated by 90 degree.
Base is located at inclinometer pipe bottom, is matched with pipe external diameter, a high-safety protecting cover for preventing silt particle from entering from ttom of pipe end in pipe.Lid is used
In protection inclinometer tube orifice, prevent debris is fallen into pipe from the mouth of pipe from influenceing normal observation work and be also made up of polyvinyl chloride, outside it
The same base of shape size.
Monitoring instrument operation principle
The operation principle of inclinometer is to measure the variable angle amount between inclinometer pipe axis and plumb line, each so as to calculate soil layer
The horizontal displacement size of point.A vertical and mutually four guide grooves in 90 ° pipe is buried generally in dam, when pipe stress becomes
During shape, clinometer probe is put into inclinometer pipe guide groove, the axle of pipe after piecewise (general mono- measuring point of 50cm) measuring deformation
Angle between line and vertical line, and the section length of measuring point is pressed, the horizontal displacement increment at different elevations is obtained respectively, then
It is cumulative paragraph by paragraph by deviational survey bottom of the tube measuring point, the actual displacement at any elevation can be obtained, finally obtains mouth of pipe accumulation level position
Move.
Problems be present in existing deep soil movement monitoring device.
1. measurement efficiency is low, measurement process wastes time and energy.The angle in a direction can only be measured every time, and spends the time
Longer, such as deep 20m inclination monitoring point need to just be surveyed, counter survey totally 80 readings（Every 0.5m readings once）, each reading
Voltage value stabilization ability reading must be waited, it is ensured that reading accuracy, a monitoring point need 2 skilled technicians' measurements
Or so half an hour, inclination monitoring point 20 or so can only be observed within one day.
2. it cannot be guaranteed that measuring point interval is certain.First, the mark on visual identity rope, the spacing of worker's drawstring are only relied on
Error be present；Secondly, timely drawstring is certain per minor tick, because inclinometer pipe has certain curvature, it is impossible to ensure in inclinometer pipe
The angle measuring instrument in portion rises the height equal with interval.

Embodiment 1
As Figure 1-3, broken-line type single shaft inclination angle location deep displacement monitor, including folding mast, some obliquity sensors
Or inclinometer, receiver, folding mast are formed by connecting by some quarter butts by hinge head and the tail, the rotating shaft of hinge is parallel to each other, each
Obliquity sensor or inclinometer are respectively mounted on quarter butt, obliquity sensor or inclinometer are connected with receiver by wired mode.
It is made up of on quarter butt with the section parallelogram of the shaft parallel of hinge, parallelogram long side and broadside,
The length of long side is more than broadside, and the acute angle of broadside is connected with the acute angle of other quarter butts by hinge.The section of quarter butt is in parallel four
It is in order that can mutually fold between obtaining quarter butt, the folding that such quarter butt is formed by connecting that the acute angle of side shape and quarter butt, which is connected with each other,
Line bar just can be folded into one, is easy to carry.
Each quarter butt size is identical, and length, width, thickness are followed successively by 200-1000mm, 40-68mm, 20-50mm.The width,
Thickness range is to ensure that quarter butt cross section is slightly smaller than deviational survey bore, and quarter butt can be and unlikely in inclinometer pipe slidably
It is too wide in being spaced, excessively relax.
An obliquity sensor is respectively mounted on each quarter butt.Because acquiescence quarter butt will not produce Bending Deformation, quarter butt can
Regard a line segment as, as long as an inclination angle just can determine that quarter butt position, therefore inclination angle sensing is respectively mounted on each quarter butt
Device can meet to require.
Obliquity sensor is single-shaft inclination angle sensor.Due to hinge can only single shaft rotate, obliquity sensor is single shaft inclination angle
Sensor.
The horizontal zeroing before on quarter butt of all obliquity sensors.So, obliquity sensor was measuring
Angle shown by journey is its angle with horizontal direction, is easy to calculating and data processing.
Its horizontal leveling plane is vertical with quarter butt length direction when obliquity sensor is installed.So, obliquity sensor is being surveyed
Angle shown by amount process is both its angle with horizontal direction, is the angle of inclination of quarter butt again, is easy at calculating and data
Reason.
Two pairs of pulleys are installed on quarter butt.The matching grooves of the pulley and deviational survey inside pipe wall, are easy to quarter butt in inclinometer pipe
Slip.

The vertical cross-section angle of length direction, calculate and determine inclinometer pipe position；
Specific Computing Principle is as shown in figure 4, set lines of the OA as two hinges on the quarter butt of inclinometer pipe bottom, length s, O are position
Put basic point known and that acquiescence is constant, because quarter butt is placed vertically, the length and width of the instant quarter butt of h, d, be again A points vertical seat
Mark and abscissa, α is obliquity sensor bottom surface and OA angles, according to trigonometric function relation：
Tan (π-α)=h/d, it may be determined that α,
s2=h2+d2, it may be determined that s,
Behind rotation β angle, according to right figure triangle relation, A is determined1Position：
Abscissa d1=s*cos (π-alpha-beta)
Ordinate h1=s*sin (π-alpha-beta)
α, s are substituted into, you can try to achieve A1Transverse and longitudinal coordinate numerical value, then with A1For basic point, A is determined2, then with A2For basic point, it is determined that
A3, a upper point is a little calculated for basic point with next obtain successively, until the position of institute a little all calculates determination on folding mast, survey
The position of inclined tube also determines that.
(2) measures the current location of inclinometer pipe, and step is the same as (1)；
(3) current locations and initial position of the according to the above-mentioned inclinometer pipe measured, the inclined degree of inclinometer pipe is calculated.
Embodiment 2
As shown in figure 5, broken-line type single shaft inclination angle location deep displacement monitor and its application method, including it is folding mast, some
