Specific embodiment
Below, the present invention is specifically described by exemplary embodiment.It should be appreciated, however, that not entering one
In the case of step narration, element, structure and features in an embodiment can also be advantageously incorporated into other embodiment
In.
In describing the invention, it should be noted that term "left", "right", " on ", the orientation of instruction or the position such as D score
The relation of putting be based on the position relationship shown in accompanying drawing 1, be for only for ease of description the present invention and simplify description, rather than indicate or
The device or element of hint indication must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that
Limitation of the present invention.Additionally, term " first ", " second " are only used for describing purpose, and it is not intended that indicating or hint phase
To importance.
As shown in figure 1, the one side of the embodiment of the present invention provides a kind of immersed tube sinking and locking backfill integrated ship, including
Catamaran, the catamaran include the upper of the first hull 1 be arrangeding in parallel and the second hull 2, the first hull 1 and the second hull 2
Portion is connected by deck bridge 3;Treat that sinking immersed tube 4 is located between the first hull 1 and the second hull 2, and be located under deck bridge 3
Side;The sinking equipment for sinking immersed tube 4 is provided between deck bridge 3 and immersed tube 4;Between first hull 1 and the second hull 2,
The left and right sides of immersed tube 4 is separately provided for the backfill conduit 5 for backfilling sand, and backfill conduit 5 is vertically connected to deck bridge 3
Bottom, and pass through deck bridge 3.During use, by the sinking equipment can by 4 accurate sinking of immersed tube into foundation trench, meanwhile, arrange
Backfill conduit 5 on the catamaran, positioned at 4 left and right sides of immersed tube locks the foundation trench of 4 left and right sides of immersed tube naturally, without the need for again
Secondary positioning, accurately can be inserted sand in the foundation trench of 4 left and right sides of immersed tube by backfilling the guiding of conduit 5, realize the lock of immersed tube
Fixed backfill.
For the ease of by sand import backfill conduit 5 in, backfill 5 overhanging deck bridge 3 of conduit above one end be connected with into
Funnel 6.By the guiding of loading hopper 6, sand can be directly entered in backfill conduit 5, when can avoid loading sand, due to returning
The problem that the mouth of pipe of filling out conduit 5 is less and causes sand to be scattered, is conducive to keeping the environmental sanitation on catamaran.
In order to ensure locking backfill accuracy of placement, backfill conduit 5 length be set to adjustable.Backfill sand
When, its mouth of pipe underwater is made until at foundation trench, can avoid sand when falling because of water impact by extending backfill conduit 5
Caused drop point skew.Meanwhile, by adjusting the length of backfill conduit 5, it is applicable to the construction of different water depth.
In order to improve locking backfill efficiency, the quantity for backfilling conduit 5 is many, as shown in Fig. 2 backfill conduit 5 is exemplary
For 6,6 backfill conduits 5 are distributed in the left and right sides of immersed tube 4, it is achieved that the uniform backfill of 4 left and right sides sand of immersed tube.
According to being installed using needing and can be removed due to backfilling conduit 5, for the ease of backfilling the installation of conduit 5 and tearing open
Remove, as shown in figure 1, being provided with for installation and removing the loop wheel machine 7 of backfill conduit 5 on deck bridge 3.When sand is backfilled, pass through
Loop wheel machine 7 is installed on conduit 5 is backfilled on the catamaran, and after backfill terminates, then removes backfill conduit 5 by loop wheel machine 7, so
The space of the catamaran can be saved, can also avoid during navigation, cause due to water impact backfill conduit 5 to damage
Problem.
As shown in figure 1, the sinking equipment includes the hanger rope 8 being connected between deck bridge 3 and immersed tube 4, and it is arranged at
On deck bridge 3, it is used for controlling the elevating mechanism 9 that hanger rope 8 is lifted.The sinking equipment that this hanger rope 8 is engaged with elevating mechanism 9,
Simple structure, take up room little and simple to operate.It is understood that those skilled in the art can also be using other conjunctions
The sinking equipment of reason.
Additionally, for the ease of positioning, being additionally provided with alignment system 10 on the catamaran, it is achieved that to the real-time of catamaran
Positioning, positions the sinking of immersed tube more accurate.
The another aspect of the embodiment of the present invention additionally provides the immersed tube sinking described in a kind of utilization any of the above-described embodiment
The construction technology of immersed tube sinking and locking backfill is carried out with locking backfill integrated ship, is comprised the following steps:
Sinking immersed tube:By 10 auxiliary positioning of alignment system, using the sinking equipment arranged on integrated ship, one will be lifted on
4 accurate sinking of immersed tube below body ship is into foundation trench 11;
Locking backfill:After sinking immersed tube 4, the left and right sides of berthing to integrated ship distinguished by least two haul ships 12, passes through
The conveying equipment 13 carried on haul ship 12, the conveying sand of backfill conduit 5 arranged on integrated ship, sand is through backfilling conduit 5
Guiding is accurately fallen in the foundation trench 11 of 4 left and right sides of immersed tube, sweeps the effect for surveying locking backfill using measuring and controlling equipment, when backfill sand
Height meet and require after, stop backfill, haul ship 12 makes a return voyage.
In a preferred embodiment, before locking refilling step, also include installing by the loop wheel machine 7 arranged on integrated ship
The step of backfill conduit 5, also include the step of backfill conduit 5 are removed by loop wheel machine 7 after backfill is stopped.In the present embodiment,
According to being installed to backfill conduit 5 using needing and being removed, the space of the catamaran can be saved, can also avoid navigating by water
Cause to backfill the problem that conduit 5 is damaged in journey due to water impact.
