The detent mechanism waterborne matched with every steel-pipe pile 3 and Underwater Navigation mechanism arrange a hydraulic power unit and control, Then four hydraulic power unit coordinated signals, every hydraulic power unit can use frequency conversion oil pump unit;After four hydraulic power units start When making four vertical oil cylinder 43 common jackings, if after once a hydraulic power unit breaks down, remaining hydraulic power unit can also Four vertical oil cylinders 43 of common driving continue to bear load, it is ensured that the safety in jacking and regulation and pressure maintaining period.
Each cylinder action can be driven after four hydraulic power unit coordinated signals;When described measuring mechanism is the displacement parameter of oil cylinder Sending master control system to the space coordinate parameters of cushion cap 2, master control system just can set according to the parameter that measuring mechanism provides The mobile data of each oil cylinder also control four hydraulic power unit actions and order about a cylinder action or the action simultaneously of multiple oil cylinder.
Master control system can be made up of PLC and computer.
This alignment system can by control the vertical oil cylinder 43 on four three-dimensional jack 4 do asynchronous and synchronous jacking, Decline, cushion cap 2 can be realized and lift, sidewinder and pitching, by controlling on four three-dimensional jack 4 first cross cylinder 44 and under water The second cross cylinder 6 action on detent mechanism can realize the torsion of cushion cap 2, traversing and vertical shift.
The present embodiment also provides for the positioning process of above-mentioned alignment system, and before the construction of location, six roots of sensation steel-pipe pile 3 is according in advance On the basis of the bottom is squeezed in the position of design, the external diameter of every steel-pipe pile may be set to 2m, and described vertical through holes 21 sets vertically Having multiple radial direction inner concave, the minimum diameter of vertical through holes 21 may be set to 2.5m.
The positioning process of above-mentioned alignment system comprises the following steps:
Step one, utilize 1 cushion cap 2 of suspension bracket to winch on many steel-pipe piles 3 and make many steel-pipe piles 3 through many on cushion cap 2 Individual vertical through holes 21, the lifting of suspension bracket 1 is completed by crane barge facility;Then crane barge loosens suspension bracket 1 and makes suspension bracket 1 be supported on four three On the vertical oil cylinder 43 of dimension jack 4, it is achieved just position;
After step 2, suspension bracket 1 are in place, the plane elevation of cushion cap 2 is adjusted, makes the on each three-dimensional jack 4 One cross cylinder 44 maintains static, now locking antifriction slide plate 45, then measures cushion cap 2 four angular coordinate by measuring mechanism, main The vertical oil cylinder 43 that Ore-controlling Role orders about four three-dimensional jack 4 according to the control hydraulic power unit action of cushion cap 2 four angular coordinate does different Step jacking operation, makes 2 four jiaos of elevation coordinate of cushion cap be in same level;Then vertical by four three-dimensional jack 4 Oil cylinder 43 synchronization of jacking up, makes the vertical coordinate of cushion cap 2 reach to design requirement, then locks the vertical oil cylinder of four three-dimensional jack 4 43, fixed bearing platform 2 elevation coordinate, the locking of vertical oil cylinder 43 can be completed by mechanically and hydraulically two kinds of means;
Step 3, open antifriction slide plate 45, make the first cross cylinder 44 of detent mechanism waterborne and Underwater Navigation mechanism One cylinder action of the second cross cylinder 6 or multiple cylinder action, make cushion cap 2 do the torsion of horizontal direction, traversing or vertical shift, Make 2 four jiaos of horizontal coordinates of cushion cap reach requirement, lock all of first cross cylinder 44 and the second cross cylinder 6, same first The locking of cross cylinder 44 and the second cross cylinder 6 can be completed by mechanically and hydraulically two kinds of means, then relocks antifriction Slide plate 45;
Step 4, squeezing into gad block 8 hold tightly between steel-pipe pile 3 and cushion cap 2 pier shaft 22, holding rear gad block 8 tightly can be with steel Pile tube 3 welds together;Also can be real with steel plate wedge between suspension bracket 1 and bearing carrier 5;
Step 5, between every steel-pipe pile 3 outer peripheral face with cushion cap 2 vertical through holes 21, weld multiple shear connector 9, make each The vertical side welding of shear connector 9 is connected in steel-pipe pile 3 outer peripheral face, makes the bottom surface of each shear connector 9 be connected on cushion cap 2, holds Platform 2 can weld with the bottom surface of shear connector 9 by pre-embedded steel slab mutually;Shear connector 9 welded after can to cushion cap 2 back cover, draw water;Then exist Concrete perfusion between steel-pipe pile 3 outer peripheral face and cushion cap 2 vertical through holes 21 of three-dimensional jack 4 is not installed, makes not install three-dimensional The steel-pipe pile 3 of jack 4 is fixed together with cushion cap 2, concrete curing after, remove suspension bracket 1, detent mechanism waterborne and under water Detent mechanism, completes whole positioning process flow process.
In above-mentioned positioning process, in order to be made intense adjustment, the coordinate of cushion cap 2 is in course of adjustment, vertical and level Coordinate still has and changes by a small margin, therefore still tackles after adjusting end in place vertically and horizontal coordinate carries out repetition measurement and adjustment, If coordinate figure deviation exceeds design error requirement, then it is repeated in being vertically finely adjusted whole again, directly with two steps of horizontal adjustment To being finally reached design requirement;Finally make cushion cap 2 pier top kernel of section position and design centre position deviation less than 10mm, top The requirement less than 10mm of the face vertical error.
Below being only one preferred embodiment of the present invention, those skilled in the art is made the change being equal to by claim Both fall within the protection domain of this case.
