If adopt full rigid support, can't satisfy the pipe coupling and refute, transport and dive full process control and split the requirement, and the utility model discloses an adaptable boats and ships of rubber buttress are refute at last, transport and the deformation of dive in-process to according to pipe coupling atress requirement formulate the rubber buttress that is adapted to this project rigidity curve.
Because the utility model discloses in adopt 4 hydraulic pressure to move fortune platform trucks and transport the immersed tube, consequently, arranged 7 rubber buttress on the lifting deck of refuting in semi-submerged correspondingly, the both sides bilateral symmetry of every platform truck is provided with two rubber buttress. As shown in fig. 2. The rubber buttresses on the central axis are spaced by 1.5 meters from front to back, and the 6 rows of rubber buttresses symmetrically positioned on the two sides are spaced by 2 meters from front to back.
The application of the utility model discloses the method of refuting long distance transport immersed tube on elasticity buttress has included following basic step:
(1) prefabricating and outfitting the immersed tube;
(2) the immersed tube is connected with the upper end of the immersed tube,
(2.1) prepressing the semi-submersible barge seat;
(2.2) overlapping the semi-submersible barge with a wharf;
(2.3) transferring and barge-in the immersed tube from the prefabricated field by using the hydraulic transfer trolley, and synchronously draining water of the semi-submersible barge in the barge-in process so that a jacking deck of the semi-submersible barge and a dock trolley rail are at the same horizontal height;
(2.4) floating the semi-submerged barge after the immersed tube is in place;
(2.5) carrying out support system conversion on the immersed tube on the semi-submersible barge, and converting from the hydraulic transfer trolley to be supported by the rubber buttress;
(2.6) the hydraulic transfer trolley is refuted, and a semi-submersible refuted tugboat is connected;
(3) after the towing ship tows the semi-submerged barge to the submerged pit, the semi-submerged barge is moored on the anchor block which is pre-selected and installed;
(4) sinking the immersed tube in water to perform water tightness test and then refuting;
(5) floating to a sinking area.
Specifically, the step (2.1) is that the semi-submersible barge presses water to sit at the bottom of the harbor basin to pre-press on the foundation of the bottom of the harbor basin so as to control the settlement of the bed in the barge-in process, and the surface of the jacking deck is flush with the rail plane of the hydraulic mobile trolley of the wharf.
The semi-submerged barge and the hydraulic transfer trolley are provided with a plurality of steel transition beams at the rail connection position of the wharf to rigidly connect the semi-submerged barge and the wharf together.
And (2.3) when the wheels of the hydraulic transfer trolley enter the semi-submerged barge deck, the semi-submerged barge starts to drain water at a speed of keeping constant pressure of the bottom of the semi-submerged barge to the bottom foundation of the harbor pool in the barge-in process.
And (2.4) after all the hydraulic transfer platforms travel to the preset positions on the semi-submersible barge, floating the semi-submersible barge by regulating ballast water, and keeping the distance between the bottom of the ship and the foundation of the sitting bottom by 1 meter. After the semi-submersible barge floats, the ship and the immersed tube deform cooperatively, and the hydraulic transfer trolley is used for adjusting and leveling the pipe joints.
And (2.5) after the semi-submersible barge floats and the hydraulic transfer trolley jacks up the immersed tube and levels, lifting the rubber buttress of the semi-submersible barge to jack the immersed tube, enabling the immersed tube to be stably supported on the rubber buttress, and enabling the hydraulic jack of the hydraulic transfer trolley to fall off the immersed tube so as to smoothly convert the supporting system.
In the process that the rubber buttress supports the immersed tube on the semi-submersible barge, the system can deform as follows:
(a) when the immersed tube is refuted, the hull is deformed downwards due to the pressure applied to the hull by the weight of the immersed tube. The deformation of the ship body is leveled by the passive support of the rubber buttress, and the deformation of the immersed tube is about 40mm through preliminary checking calculation.
(b) In the immersed tube transportation process, as a ship swings, the immersed tube swings along with the ship body and is stressed to change, whether the support can be quickly self-adaptive to the stress change or not is considered, and the stress of the immersed tube is kept uniform through the elastic property of rubber. The influence of waves is superposed according to the state of still water, and the deformation generated by the ship body and the immersed tube is about 2 mm.
(c) When the immersed tube is refuted, the immersed tube gradually floats, the pressure applied to the ship body is reduced, and the deformation of the ship body is gradually reduced. But the originally leveled rubber passive support would cause a reverse arch. Consider initially about 42 mm.
In order to reduce the influence of the lifting deck inverted arch on the deformation of the immersed tube during the submergence period of the semi-submerged barge, prepressing is arranged on the rubber buttress, and the deformation is stabilized by using the self-locking device.
According to a preliminary rubber elastic stress deformation curve (as shown in figure 5), the rubber support pad is pre-pressed before the immersed tube pier, so that the rubber cushion block is deformed by 42mm in advance. Then the rubber cushion block is self-locked through the bolt lock catch, and then immersed tube pier falling operation is carried out. And (4) transporting the immersed tube to a submerging pit, and opening the self-locking device before submerging the immersed tube to reduce the inverted arch deformation of the immersed tube.
The immersed tube generates deformation of the semi-submerged barge under the action of gravity, and the deformation is supported and leveled by the rubber buttress on the semi-submerged barge. But in the submerging process of the step (4), the buoyancy is increased, and the semi-submerged barge begins to invert and restore to the original shape. The semi-submerged barge submerges in a non-uniform ballast mode to reduce the deformation of the semi-submerged barge due to the increase of buoyancy in the submerging process.
In the submerging process of the semi-submersible barge, the semi-submersible barge loading computer can monitor the deformation condition of a ship, and simultaneously, the position and the speed of ballast water in each cabin are regulated and controlled by combining the immersed tube deformation measurement control system, so that the weight of the ballast water in each ballast cabin is controlled, and the deformation problem of the semi-submersible barge in the submerging process is effectively relieved.
The above embodiments are only used for illustrating the present invention, and not for limiting the present invention, and those skilled in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention, so that all equivalent technical solutions also belong to the scope of the present invention, and the protection scope of the present invention should be defined by the claims.
