Description
Technical field
The present invention relates to a kind of piling positioning technique, particularly pile sinking operational method is accurately located in a kind of off-lying sea.
Background technology
At present, away from the off-lying sea pile sinking measurement and positioning of water front, be all based upon on GPS location technology basis, because accurately setting up of off-lying sea datum station is not easy to realize, and utilize land-based area datum station due to distance, the signal errors that the rover station on boats and ships receives is larger.Therefore, the measurement and positioning at the relative pilespacing of off-lying sea pile sinking away from water front generally all adopts the way of the auxiliary positioning such as on-the-spot bracing wire control, locating rack control to realize.Its defect is that measuring method is more original, complex process, and be difficult for realizing when pilespacing is larger relatively.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provide a kind of for the position of pile sinking being carried out in real time at off-lying sea pile sinking operation process and locating accurately, by computer, inform intuitively site operation personnel simultaneously, make the off-lying sea of the position of the control pile sinking that they can be promptly and accurately accurately locate pile sinking operational method.
Technical problem to be solved by this invention is to realize by following technical scheme, and the present invention is that pile sinking operational method is accurately located in a kind of off-lying sea, is characterized in: its workflow is as follows:
(1) by GPS, locate and squeeze into the first pile foundation stake;
(2) on the first pile foundation stake stake top, hydraulic pressure internal-expansion type base is set, by the action of expansion chuck hydraulic jack in the stake of the cover of three on hydraulic pressure internal-expansion type base Complete Synchronization, the center of automatic capturing the first pile foundation stake, and adjust hydraulic pressure internal-expansion type base to level by electrolevel; Then the head seat of 360 ° of rotations is installed at the center position of the first pile foundation stake, three laser range sensors that are positioned at same plane and are parallel to each other are installed on head seat, the laser that laser range sensor sends is at same plane and parallel;
(3) thus by three laser range sensors in the first pile foundation stake, the measurement of three difference distances on the second pile is calculated to the physical location of the second pile, then the design stake position fictionalizing with computer shows simultaneously, and operating personnel squeeze into second pile sinking according to image capturing position; Then on the second pile, set up equally a set of with identical in the first pile foundation stake system, three laser that are arranged on same head seat, send are at same plane and parallel laser range sensor; Rotate the head seat on the first pile foundation stake and the second pile, make all six laser range sensors can measure the data of the 3rd pile;
The 3rd pile physical location that (4) six laser range sensors capture is reflected on computer screen, site operation personnel is according to the design stake position fictionalizing showing on screen and actual stake bit position deviation, adjust piling boats and ships to design stake position, squeeze into the 3rd pile;
(5) by above-mentioned six laser range sensors, locate the measurement technique of a pile, alternately complete the accurate measurement of pile sinking in whole engineering region.
Technical problem to be solved by this invention can also further realize by following technical scheme, described hydraulic pressure internal-expansion type base is evenly provided with three supporting legs at grade, each supporting leg is provided with stake roof joint the horizontal adjustment bolt that regulates hydraulic pressure internal-expansion type base level, and the soffit of each supporting leg is provided with expansion chuck hydraulic jack in the stake matching with stake top inwall.
Pile sinking operational method is mainly to follow not 3 mathematical theorems that can determine a circle on same straight line of certificate, measure respectively the position of second pile sinking and the 3rd pile sinking, and with computer in virtual correct pile sinking position compare to determine whether second and the 3rd pile sinking put in place, whether its home position and correct home position deviant are how many, within the error range allowing.
Compared with prior art, there is following advantage in the present invention:
(1) sample frequency is high
The laser range sensor that this cover system is used can reach 50Hz for AR1000 sensor, its sample frequency.
(2) operation interface is directly perceived
This cover system is directly used the position of three (or six) laser range sensor Real-Time Monitoring pile bodies, and fictionalizes on computers the position of pile body, simultaneously by reality stake bit data typing computer showing on screen in advance.Site operation personnel can, according to surveying the deviation of stake position with theoretical, adjust very easily.
(3) accuracy of judgement
The laser range sensor that this cover system adopts in measure portion, itself certainty of measurement can reach 3mm.This cover system is measured because adopting three (or six) laser range sensors directly to get three points on pile body simultaneously, has reduced the entire system error of bringing because of cloud platform rotation angular error, and accuracy is higher.
(4) simple to operate
The measure portion of this cover system is automatically completely, and operating personnel only need to omit the angle of inching head seat when pile body has very large change by instruction, to guarantee that the laser that sensor is sent can be irradiated on the measured pile body of needs.
(5) scope of application is wider
Native system adopts laser to find range, and off-lying sea sighting condition is better, if do not considered the weather effect factors such as extraneous dense fog, can guarantee that survey data can distortion within the scope of 100 meters.Measurement of pile foundation for off-lying sea detached building has good application prospect.During as off-lying sea Construction of Wind Power, the measurement and positioning of the measurement and positioning of the many pile foundations of blower fan, off-lying sea anemometer tower pile foundation, off-lying sea job platform pile foundation construction etc.
