Abstract
The utility model discloses a self-sliding drop type flexible slide way of an ocean platform and belongs to the field of foundation engineering in the shipbuilding industry. The self-sliding drop type flexible slide way consists of a slide way main body structure and a bulkhead wall, wherein the bulkhead wall is mainly formed by laminating a plurality of net cage stones (23); cobble stones are refilled behind the bulkhead wall; a grouting foundation bed (14) which is inclined to a water area is arranged on the top surface of the bulkhead wall; a prefabricated reinforced concrete slide way plate (11) is paved on the grouting foundation bed (14); the slide way main body structure is fixed on the prefabricated reinforced concrete slide way plate (11). The self-sliding drop type flexible slide way of the ocean platform has the beneficial effects that a ship launches in a free dropping manner instead of a complete floating manner; the length of the slide way is greatly reduced; the slide way plate can be connected with an upper sliding plate in a random form; steel rails are eliminated; the problem of launching of an ocean drilling platform and like products can be safely, efficiently and economically solved.
Description
Technical field
The invention belongs to the hull launch-way foundation field of engineering technology of shipbuilding industry, particularly relate to a kind of platform from sliding drop type Flexible slideway technology.
Background technology
Slideway is the water conservancy project structures of shipbuilding industry for water under boats and ships or ocean engineering product.Boats and ships, when building and repair, need pull water under disembarkation or rolling along the track of certain gradient, usually are called water under pier, and this dedicated track for water under pier on boats and ships is called slideway.Under this slideway the characteristics of water be hull along the track rolling until the complete floating of hull, break away from slideway, so slideway is long, structure is more complicated, expense is higher, and underwater structure to take waters more, ship's navigation in port is caused to adverse effect.
The present invention, according to different thinkings, adopts different materials design fixed way, solves the lower water problems of marine drilling platform or similar products.Reach purpose safe, efficient, that save.Do not take simultaneously waters, save water area resource, do not affect ship's navigation in port.
Summary of the invention
The invention provides a kind of platform from sliding drop type Flexible slideway, be comprised of slideway agent structure and slideway basic design, the slideway agent structure is comprised of ferro-concrete chute board, upper slide, lower skateboard and anchoring piece; Between upper slide and lower skateboard, be sliding surface, hull rides on upper slide, and upper slide glides along sliding surface; The ferro-concrete chute board is prefabricated board; Ferro-concrete chute board upper surface is every 1.5 meters pre-embedded steel slabs; A plurality of chute boards of ferro-concrete with pre-embedded steel slab are sequentially tiled and are placed on the slideway basic design; On ferro-concrete chute board surface, lay lower skateboard, the bottom surface of lower skateboard is embedded with the anchoring piece corresponding with the pre-embedded steel slab position of ferro-concrete chute board; By anchoring piece and the pre-embedded steel slab welding be embedded on lower skateboard.
The slideway basic design is comprised of the back filled foundation at bulkhead wall, bulkhead wall rear, domatic grouting bedding, concrete foundation beam and blotter; A plurality of net cage piece stone is stacked to form the hypsokinesis angle be the bulkhead wall of 0 °～20 °; The basis of net cage piece stone is piece ground mass bed; Piece ground mass bed is seated on the bearing stratum that meets requirement for bearing capacity; Piece ground mass height of bed journey requires to determine with geologic condition according to falling drinking water; The foundation beam blotter is laid near the bulkhead wall end in net cage piece stone top; The concrete foundation beam is placed on the foundation beam blotter along the end of bulkhead wall; Piece stone in the backfill of bulkhead wall rear, in compacting, piece stone forms to the back filled foundation of waters inclination, and the end face of back filled foundation extends to the place, bottom surface of concrete foundation beam inboard; The back filled foundation end face gradient and end elevation are determined according to Launching processing and water level condition; The back filled foundation end face is laid geotextile; Backfill piece stone on geotextile, perfusion mortar, form from back filled foundation and extend to domatic grouting bedding concrete foundation beam upper surface and that tilt to waters always; The upper surface of the upper surface of domatic grouting bedding and concrete foundation beam is bordered; Domatic grouting bedding top is blotter; A plurality of chute boards of ferro-concrete with pre-embedded steel slab are sequentially tiled and are placed on blotter.
The ferro-concrete chute board is in the situation that the water level permission also can be cast-in-place.
Piece ground mass bed adopts anticorrosive material.
In slideway basic design end face width and the length scope between 20 to 100 meters.
The invention has the beneficial effects as follows one, the slideway main body adopts flexible structure, can effectively absorb under platform the impact energy slipped in the water process, avoids product is damaged, and guarantees product safety; Two, platform arrives way end and freely falls into water, significantly shorten slideway length, thereby reduce construction costs, and minimizing is conducive to taking full advantage of of water area resource to the taking of waters; Three, platform glides voluntarily by gravity on slideway, saves lower water cost; Four, flexible structure is to stressed strong adaptability, and appropriate products is in extensive range; Five, slideway is not established ground way, and to product yardstick strong adaptability, the product of width 20～100m is water under available the present invention all.Main structure body is piece stone, cement concrete and withstanding corrosion net cage etc., and the daily attention expense seldom.Six, with traditional slideway, compare, the two similarity be all to adopt flexible foundation, difference be lower water mode from complete floating, change into freely fall, slideway length significantly shortens, chute board can be connected, cancel rail etc. with the slide plate of top arbitrary form.In a word, the present invention can solve the lower water problems of marine drilling platform and similar products safely, efficiently, frugally.The present invention is applicable to the lower water operation of various devices on marine drilling platform and equipment.
