Abstract
The invention discloses a semi-submersible barge transverse side launching method. By adding a transverse slideway on the basis of an ordinary launching semi-submersible barge longitudinal slideway, a side launching mode can be achieved; in the side diving period, a ballast pump is started, water is pressed into the a ballast tank from the exterior of a ship body, a main deck transversely submerses the water level, eight water level rods are uniformly mounted on the main deck so as to control the ship body to be balanced, when the ship body submerses for 1.5 m away from the bottom of the river bed, the ballast pump is stopped, the submersion depth is achieved, and heavy articles can be dragged onto the ship body. Due to the adjustment on the track and the structure, a side launching mode is adopted, launching of a large-size ocean structure module can be achieved, the technical level that multiple purposes can be achieved through one barge is achieved, a semi-submersible barge which is limited in ordinary ship submerge at present has relatively great practical values, and relatively great economic values can be achieved with relatively small economic investment.
Description
Technical field
The present invention relates to ship loading field, particularly a kind of partly diving refutes side launching method.
Background technology
Along with the anti-exhibition of marine technology, level land formula Shipbuilding Mode is formed stand like the legs of a tripod with building berth, dock shipbuilding gradually, and becomes Japan and Korea S's main flow method of construction gradually.But compare building berth and dock, the front capital of level land shipbuilding drops into less, and coordinate segment total group, huge complete cross section closes up greatly simultaneously, have and improve the advantage such as shipbuilding efficiency and output, minimizing investment cost, very fast formation production capacity.
On the other hand, along with the utilization to marine resources, the demand of Offshore Platform also increases day by day.With reference to Shipbuilding Mode, utilize level land forming method equally, need half to dive to refute or floating drydock to coordinate lower water.In view of the oversize of console module, its lower water half dive refute that differing dives with the lower water of conventional freighter half surely and refute general.So, under the platform module of design specialized, water special half is dived and is refuted and can leave unused by shipbuilding resource long-term.
Common caisset is widely used in the good port engineerings of ground such as harbour, trestle, break-water due to advantages such as its resistance to overturning are good, speed of application is fast, durable in use, but launching caisson goes out to transport to toward the restriction by fabrication yard condition.In experience in the past, precast caisson generally needs special precast field, adds that slideway supporting with it, floating drydock or large lifting equipment just can make launching caisson, is just difficult to play the advantage using caisset as not having special precast field.By engineering practice in recent years, there is no special precast field in engineering locus or establish interim fabrication yard away from the area of special precast field.
Summary of the invention
Goal of the invention: for above-mentioned defect, technical matters to be solved by this invention there is provided a kind of partly diving and refutes side launching method, shortens Time Of Launching, improves the degree of utilization of resource.The present invention not only can adopt half to dive to common goods and refute side launching method, and particularly convenient for precast caisson side launching, fast, does not need special precast field, small investment, and construction preparatory stage is short, the method for Suitable flow construction.
Technical scheme: in order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: the invention provides a kind of partly diving and refute side launching method, under routine water half dive refute longitudinal slipway basis on increase sideslipway thus realize the pattern of side launching, the described horizontal dive stage: start ballast pump, ballast tank is entered from the outside setting-out of hull, main deck laterally enters below the water surface, hull balance is controlled by 8 the drinking water mark posts evenly installed on main deck, when hull slips into 1.5m bottom riverbed, stop ballast pump, reach submerged depth, weight is dragged on hull.
Further, in order to more accurately by water under goods, described half dives refutes molded breadth 50m, and main buoyancy tank four end establishes high building, horizontal clear spacing 36m between high building, longitudinal clear spacing 132m.
Further, in order to adapt to larger goods, such as caisson and so on, described longitudinal slipway is twice, respectively long 160m, and overall length is 320m; Described sideslipway has 4 roads, respectively long 50m, and overall length is 200m.
Further, by detecting, described vertical sideslipway span 32m, bearing load is 65t/m
2, maximum lifting force reaches 15000t.
Further, described weight is caisson.
Further, launching caisson method is as follows:
1) half latent refuting vertically is pulled in shore, align caisson and treat lower water bulkhead wall Primary Location;
2) when half dive refute waterflooding adjustment stem draft aft in cabin until state of equilibrium time, accurately adjustment accommodation makes ship dock with trolley track on the bank, and then water filling makes stem be supported on bulkhead wall cushion cap bearing, simultaneously by hull leveling;
3) land prefabricated caisson is jack-uped and is placed on transport trolley fixed;
4) with being placed in half latent winch band running block of refuting, transport trolley two barrels of caissons tractions being dived on barge bow deck to half, and chassis and hull are fixed;
5) partly latently will refute front deck, middle deck draining floating, and make stem depart from bearing and float;
6) start ballast pump, enter ballast tank from the outside setting-out of hull, main deck laterally enters below the water surface, control hull balance by 8 the drinking water mark posts evenly installed on main deck, when hull slips into 1.5m bottom riverbed, stop ballast pump, reach submerged depth, caisson is dragged on hull.
Beneficial effect: compared with prior art, the present invention has following characteristic and advantage: the present invention is by laterally increasing slideway, making half to dive and refuting the side launching that can realize lower aquatic products, the river boat of about length 50m can direct water under lateral translation, substantially reduces Time Of Launching.The present invention is by the adjustment to track and structure, take the pattern of side launching, the lower water of large ocean construction module can be realized, reach and refute multiplex technical level, make originally only to be confined to half of water under normal shipboard barge of diving and obtain larger practical value, realize larger economic value with less economic input.The present invention not only can adopt half to dive to common goods and refute side launching method, and particularly convenient for precast caisson side launching, fast, does not need special precast field, small investment, and construction preparatory stage is short, the method for Suitable flow construction.
