(3) beneficial effect
A kind of rubble leveling device that the utility model provides, simple in structure, adopt the jackstone pipe to the bedding jackstone, bedding adopts leveling head to strike off processing when existing the high deviation of calibration to surpass certain limit, has guaranteed the compacting leveling of bedding, and the flatness of bedding is high.
Description of drawings
Fig. 1 is the structural representation of a kind of rubble leveling device of the utility model;
Fig. 2 is sonar system structural representation in the utility model.
In figure: 1, jackstone pipe; 2, leveling head; 31, calibration sonar; 32, lay the measurement sonar; 4, bedding.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As Fig. 1, a kind of rubble leveling device of the present utility model, comprise jackstone pipe 1, the top of jackstone pipe 1 and bottom are respectively equipped with GPS navigation system and leveling head 2, jackstone pipe 1 is used for the bedding jackstone, leveling head 2 is used for bedding is struck off, and the GPS navigation system is used for confirming plan-position and the end absolute altitude of jackstone pipe 1.
Jackstone pipe 1 comprises up and down two parts, and top is fixing supervisor, and the bottom is telescopic balance pipe, and balance pipe is connected with leveling head 2.Balance pipe is stretched by the Driven by Hydraulic Cylinder of being located on jackstone pipe 1.This hydraulic cylinder can be made as many, and many hydraulic cylinders are evenly distributed on balance pipe, act on simultaneously the length of adjustment pipe, to satisfy the required precision of rubble leveling; And being provided with the hydraulic cylinder extension sensor on every hydraulic cylinder, this telescoping sensor is used for accurately measuring the flexible stroke of hydraulic cylinder.Hydraulic cylinder can be made as four.
Confirm the plan-position and end absolute altitude of jackstone pipe 1 by the GPS navigation system after, the balance pipe flexible stroke that carries out is repeatedly confirmed, guarantee that hydraulic cylinder extension length can satisfy accommodation and lay needs, thus, lifting jackstone pipe 1 again in the process of deployment at an accommodation.
Be provided with the level-sensing device for detection of controlling level in jackstone pipe 1, this level-sensing device can adopt Plumb-bob Material Level Meter.Measure by weight controlling level in the jackstone pipe is controlled within the specific limits, need to stop during measurement adopting weight to measure after conveying again, its reason is that the building stones of avoiding weight to be fallen bury, and damages wire rope when mentioning weight.In process of deployment, weight can continuously be measured controlling level in the jackstone pipe with certain frequency.The pulling force of controlling the winch of weight can not be too small, and too small words make weight to regain because the speed of laying piece makes weight to spread into bedding along with rubble, should control when pulling force keeps weight to drop down onto charge level to stop.
Also be provided with the clinometer for detection of jackstone pipe inclined degree on jackstone pipe 1, the inclined degree of jackstone pipe detected according to clinometer is revised position and the height of jackstone pipe, to guarantee the flatness of bedding.
This rubble leveling device also comprises sonar system, and this sonar system is arranged on leveling head 2, for detection of seabed troughstand and bedding absolute altitude.As shown in Figure 2, sonar system comprises calibration sonar 31 and lays and measure sonar 32, and the sonar velocity of sound of calibration sonar 31 is transferred to a suitable value, and the velocity of sound of then laying of bedding 4 being measured sonar 32 transfers to calibrate sonar 31 identical.Be subjected to the impact of the factors such as the depth of water, water temperature, salt concentration to make measured value produce error due to sonar, therefore all need to calibrate during each absolute altitude of measuring bedding.
A kind of rubble leveling device that technique scheme provides, be used for the construction of seabed/river bed bedding, it is simple in structure, the jackstone pipe is to the bedding jackstone, if surpass ± 40mm according to the high deviation of calibration of the testing result bedding of sonar system, can adopt leveling head to strike off processing, guarantee the compacting leveling of bedding, the flatness of bedding is high.The 2nd GPS navigation system by jackstone pipe top receives three-dimensional coordinate data and controls in conjunction with the absolute altitude that the stroke of jackstone length of tube, jackstone pipe angle of inclination and bottom liquid cylinder pressure carries out the rubble bedding, and its certainty of measurement is controlled accurately.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
