Detailed description of the invention
As shown in Figure 1 and Figure 2, water suspender under rectangular caisson handling provided by the present invention, comprise hoist cable 2, snap ring 3, steel corner protector 4 and lower hoist cable 5, upper hoist cable one end is hung on crane ship double hook 1, the other end is connected with lower hoist cable by snap ring, and lower hoist cable is revealed all the details by steel corner protector 4 pairs of rectangular caissons.
As shown in Figure 4, Figure 5, described steel corner protector is made up of cambered surface steel plate 6, vertical corner protector steel plate 7, horizontal corner protector steel plate 8 and separated time steel plate 9, vertical corner protector steel plate and horizontal corner protector steel plate vertical welding, it is cambered surface steel plate outside it, the two ends up and down of cambered surface steel plate respectively with vertical corner protector steel plate and horizontal corner protector Plate Welding, separated time steel plate is positioned at cambered surface steel plate both sides, is welded in outside vertical corner protector steel plate and horizontal corner protector steel plate.Further, horizontal corner protector steel plate 8 is three stackedly to add, and the corner of separated time steel plate 9 is circular shape.
As shown in Figure 6, steel corner protector is stuck in the oblique toe position of caisson 10, and lower hoist cable contacts with the cambered surface steel plate of steel corner protector through bottom caisson, thus avoids lower hoist cable to damage oblique toe.
In addition, as shown in Figure 3,4 two ends are adopted with the steel wire rope of eye splice as lower hoist cable, and each placed opposite in caisson both sides two steel corner protectors, the lower hoist cable radical that single steel corner protector is corresponding is 2, uses after adopting doubling.Equally, upper hoist cable also adopts two ends to form through doubling according to actual conditions with the steel wire rope of eye splice, and sectional continues spreading.
Adopt that said apparatus carries out ground hook to rectangular caisson, integral lifting of revealing all the details and automatically disengaging under water, its processing step is as follows.
Crane ship in being positioned at fortune wharf apron, on double hook hang on hoist cable.
Crane ship is stopped perpendicular to going out to transport wharf apron, and adjustment crane ship position makes hoist cable be positioned to treat directly over handling rectangular caisson, and makes hoist cable lower end in the height of rectangular caisson base plate.
With seizing wire as messenger, with snap ring, messenger one end is connected on lower hoist cable eye splice, first goes out messenger with steel hook from caisson bottom traction, then draw messenger with loading machine thus draw lower hoist cable, make it through bottom caisson, carry out the preparation that lower hoist cable is revealed all the details.
Lower hoist cable passes after bottom rectangular caisson, lays and adjusts position, make it accurately be stuck in the desired location of the oblique toe of rectangular caisson, and be fixed on lower hoist cable with seizing wire steel corner protector.
After steel corner protector is laid, hook weighed in the hand by hoisting commanding staffing crane ship, supreme hoist cable eye splice or overhead about 0.5 meter, its doubling stage casing, the lower hoist cable pulled out by messenger on ground by workmen is connected with upper hoist cable, in the middle part of lower hoist cable, doubling end adopts on the snap ring eye splice that is connected to hoist cable or its doubling stage casing, and two eye splice of side also adopts snap ring to be connected with upper hoist cable in addition, shared 8 snap rings of connection, every 2 snap rings are one group, and described snap ring is shape of a hoof snap ring.
Lifting checks, and rectangular caisson is winched to the water surface: crane ship slowly hooks up, and workmen checks whether steel corner protector and the oblique toe contact surface of caisson tightly coincide, and crane ship continues to hook up to caisson overhead 0.5 meter of height, checks that whether hoist cable suspender is normal further; After normal, workmen withdraws around caisson, and crane ship slowly to hook up to caisson overhead about 1.0 meters, moves ship backward and makes caisson shift out fortune wharf apron, slowly weigh hook subsequently in the hand and make Bottom plate of sinkbox close to the water surface.
Crane ship continues to weigh hook in the hand, and when rectangular caisson inlet opening there is not below upstream face, stop weighing hook in the hand, now workmen climbs up caisson top by rope ladder, opens into water gate valve to water filling in rectangular caisson, until water level meets rectangular caisson and to swim stable requirement in each cabin.
Rectangular caisson stablize floating after, haul rectangular caisson to installation region: finely tune adding water in each cabin of caisson, until corner freeboard is close.Weigh hook after leveling caisson in the hand to caisson floating stable, crane ship continues to weigh hook in the hand and departs from caisson completely to steel corner protector subsequently, and push boat pushing tow caisson makes itself and suspender throw off completely, and by tugboat by Caisson Transportation to installation region, complete entirety under water and automatically disengage.
After rectangular caisson and suspender depart from completely, crane ship hooks up, and by lower hoist cable lifting water outlet, steel corner protector is with lower hoist cable water outlet, and crane ship stranded cable moves forward to wharf apron subsequently, unties one-sided snap ring, enters the next rectangular caisson flow process of lifting.
