Problems solved by technology

The characteristic of this kind of slideway launching is that the hull slides along the track until the hull floats completely and breaks away from the slideway. Therefore, the slideway is longer, the structure is more complicated, and the cost is higher, and the underwater structure occupies more water area, which is difficult for ships in the port. cause adverse effects

Embodiment Construction

[0012] Below in conjunction with accompanying drawing, the present invention is described in detail:

[0013] The self-sliding and falling flexible slideway of the offshore platform is composed of the main structure of the slideway and the foundation structure of the slideway. The foundation structure of the slideway consists of the bank wall, the backfill foundation behind the bank wall, the slope grouting foundation bed (14), and the concrete foundation beam (21) and crushed stone cushion (13); stack a plurality of net cage block stones (23) to form a bank wall with a backward inclination angle of 0°~20°; the foundation of the net cage block stone (23) is block stone foundation bed ( 24); the block stone foundation bed (24) is located on the bearing layer (3) that meets the bearing capacity requirements; the elevation of the block stone foundation bed (24) is determined according to the drop draft requirements and geological conditions; the top of the cage block stone (23) L...

Abstract

The invention discloses a self-sliding dropping type flexible slideway of an ocean platform, and belongs to the field of basic engineering of shipbuilding industries. The self-sliding dropping type flexible slideway consists of a slideway main body structure and a bulkhead wall, wherein the bulkhead wall is mainly formed by stacking a plurality of net cage stones (23); stones are backfilled behind the bulkhead wall; the top of the bulkhead wall is a grouting foundation bed (14) inclined towards a water domain; a prefabricated steel bar concrete slideway plate (11) is paved on the grouting foundation bed (14); and the slideway main body structure is fixed on the prefabricated steel bar concrete slideway plate (11). The self-sliding dropping type flexible slideway has the beneficial effects that a ship body sinking mode is changed from complete floating into free dropping; the length of the slideway is greatly shortened; the slideway plate can be connected with a sliding plate which is positioned on the upper part and is in any shape; a steel rail is saved; and the problem that an ocean drilling platform and similar products have difficulty in entering water can be safely, efficiently and economically solved.

Description

technical field [0001] The invention belongs to the technical field of the basic engineering of a ship launching slideway in the shipbuilding industry, and in particular relates to a technology of a self-sliding and falling flexible slideway for an ocean platform. Background technique [0002] The slideway is a hydraulic structure used in the shipbuilding industry for launching ships or marine engineering products. When a ship is being built and repaired, it needs to be dragged ashore or slipped into the water along a track with a certain slope, which is usually called launching the pier. This special track for launching the ship is called a slideway. The characteristic of this kind of slideway launching is that the hull slides along the track until the hull floats completely and breaks away from the slideway. Therefore, the slideway is longer, the structure is more complicated, and the cost is higher, and the underwater structure occupies more water area, which is difficult...
