The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1 to Fig. 3, a kind of center fixation formula sedimentation dish comprises circular sedimentation dish 1; Be fixed on circular sedimentation dish 1 supercentral sedimentation bar 2; The top of sedimentation bar 2 is a measuring staff 3, and said measuring staff 3 is provided with measures the sign 3-1 of portion, is coated with sign line 3-2 red and white in the said measurement sign portion; The two ends up and down of measuring the sign 3-1 of portion are provided with and the vertically disposed sign bar of measuring staff 3-3; Said sedimentation bar 2 is a tubular structure, and said sedimentation bar 2 is assembled by several sections sedimentation body of rod 2-1, connects through swivel nut 4 between every section sedimentation body of rod 2-1; Said measuring staff 3 spiral shells are contained in the sedimentation body of rod top of top, and said sedimentation dish 1 is provided with and the corresponding centre bore of sedimentation bar centre bore; Said sedimentation dish structure also comprises center fixation bar 5; Said center fixation bar 5 is installed in the centre bore of sedimentation dish 1 and sedimentation bar 2; Said center fixation bar 5 is assembled by several sections center fixation body of rod 5-1, connects through swivel nut 6 between said every section center fixation body of rod 5-1.
For improving the intensity of sedimentation dish, the said sedimentation bar that is fixed together with the sedimentation dish is provided with stiffener 7 on every side, and said stiffener welds together with sedimentation dish and sedimentation bar respectively.
The utility model method for using,
Lay: after at first the center fixation bar being delivered to the setting-out position through tender, the accommodation is lived in following front and back two grapplings.The dispensing personnel are slowly pounded the center fixation bar the mud face with iron hammer from ship one side, and the not open close swivel nut spreading center fixation bar of crossing can't make it continue downwards until iron hammer., this process need to adjust the verticality of center fixation bar when noting at any time.Discharge the sedimentation dish then, operating personnel discharge the sedimentation dish immediately from ship one side, sedimentation rim center fixation bar is penetrated; The sedimentation dish is seated on the former mud face; Continuous then spreading sedimentation bar exceeds about water surface 2m until measuring sign portion, and the dispensing of sedimentation dish is accomplished; To detect its verticality after the dispensing of sedimentation dish is accomplished, in time adjust if any tilt condition.
Calibration: because that the soil property in hydraulic reclamation district distributes is more even, in the works area in the cofferdam 300 meters along the line every at a distance from about 500 meters sedimentation bars of laying.After sedimentation bar assembled on site is accomplished, use steel ruler to measure Vertical right angle observation and be tagged to the height of bottom surface and carry out respective record.
The sedimentation dish is laid and is required:
(1) lays in strict accordance with design attitude;
(2) the sedimentation dish should keep vertically sinking putting;
(3) measuring staff segmentation connection should be enough firm.
Use RTK GPS to measure its exact position after the sedimentation bar is laid and accomplished, and on the sedimentation bar, numbering is set, also can use the checkmark field of different colours to distinguish at masthead.For the ease of measuring the angle of inclination of sedimentation bar, two intersection measurement marks up and down are set on the sedimentation bar, the mark discrepancy in elevation is 1m up and down.
Observation:, therefore should accomplish 24 hours sedimentation bars and can carry out level measurement first after stable laying because the former mud face in hydraulic reclamation district belongs to subgrade.The distance that is tagged to sedimentation bar chassis according to observation can be extrapolated the absolute altitude of sedimentation bar bottom, and calculates the initial settlement amount that the deadweight of sedimentation bar causes with reference to original mud face height gauge.
Preceding 3 months observation cycles are weekly during the dredge fill, and observation in every month once can be encrypted observation in case of necessity after 3 months.Observe operation in strict accordance with the time interval of agreement in the observation cycle; On each operating point, establish the station respectively during each observation; Observe the vertical angle of each sedimentation bar measurement markers nearby; All be as the criterion with sedimentation bar marked, simultaneously observed result charged to the observational record form, the technical requirements of survey station each item is carried out according to the regulation of " marine traffic engineering specifications of surveys " (JTJ 203-2001).
Because the sedimentation bar receives the influence of barged-in fill and current, very easily causes the inclination of the body of rod.For this tilt quantity is measured, the method that one time every month use angle crosses during settlement observation is measured and is observed the plane coordinates of mark up and down, and calculates the angle of inclination of sedimentation bar in view of the above.
