The invention relates to the field of hydraulic engineering construction, namely, the lifting of precast-monolithic reinforced concrete construction for boats, intended for use in the open coast, as well as to the method of its construction.

According to the results of patent information research, including on the INTERNET, you can see that salvaging structures are characterized by the presence of ship-carrying paths in the form of the rails with movable thereon ship-carrying trolleys, which is not only cumbersome, but also in the open coast in shallow water in the presence of floating debris and transported sediment leads to an emergency condition salvaging structures and the wear of the rails. Known in hydraulic engineering salvaging facilities in the form of sheds, which, depending on the design of ship-carrying paths have the sleeper-ballast base in the form of reinforced concrete beams on piles or columns, as well as concrete slabs on a compacted layer of sand, gravel or crushed stone do not have sufficient stability and reliability as prone to washing out in the open coast.

In addition, all known salvaging structures are not designed for lifting boats in the open coast, so their Builder of the creation and operation in these conditions remains an unsolved problem.

Known slip lifting and lowering vessels copyright certificate №1698133, CL B63C 3/04, publ. 15.12.91, bull. No. 46, which contains Kosyakova truck (their number depends on the length of the vessel), each trolley moves own winch with rope; extreme trucks equipped mounted on pylons reel wound with them cables supported in taut tensioning mechanism - block system with counterweights, equipped on the shore; on the pylons mounted sensors skew receiver and emitter. When lifting the vessel, the winding of the cables on the drums is provided by chain drives, stretched between the sprockets mounted on the axes of the upper rollers trucks and drums. During the ascent and the descent vessels connects the control circuit of electric winches Kosyakova trucks and scheme locking dependency, which is designed for continuous monitoring of the position of the lifting or descent of the vessel and immediate automatic shutdown of all electric winches Kosyakova trucks when creating dangerous distortions of the vessel.

The known device has a complex system of movement Kosyakova trucks on the track, the inevitable distortions, to eliminate which uses a system of balances and sensor bias. In addition, such a slip is not intended to be the Yong for lifting boats in the open coast.

A device for draining the vessel for a patent for invention №2337038, CL B63C 3/00, publ. 27.10.2008, which includes a slip with horizontal and inclined parts and laid them on the track, on which are respectively mounted with the possibility of forward movement berth and Kosyakova truck to move which has a traction winch; rails near the line of intersection of the horizontal and inclined parts of the building are laid on beams with ballast cargo mounted can be rotated from the horizontal to the inclined position corresponding to the corner of the inclined part of the slip, and back via the hinge, the transmitting vertical load from the stacker trucks on the ground and installed in the vertical plane. The descent of the vessel along the inclined part in the known device is traction winches that raise Kosyakova truck and transport the vessel to the location Kosyakova trucks on rails horizontal part of the stacker trucks.

Known analogue has a complex structure due to the complexity of the leveling device of balancers with ballast loads, due to the complexity of the device and operation of the actuator in the form of a hydraulic cylinder, because of the need to use the track, which in the conditions of the indoor coast in shallow water in the presence of floating debris and transported deposits leads to the dangerous condition of the slip and wear of the rails.

A common disadvantage of the above slips with ship-carrying rail tracks is that they, firstly, extremely cumbersome, uneconomical, there is a complex transfer vessel with inclined on the horizontal part. In addition, such slips are not designed for lifting boats in the open coast.

The closest analogue of the present invention is adopted slip boathouse, which has an inclined track mounted on the base of precast concrete slabs with holes; precast concrete slabs installed in the surface part and the horizontal berth places on compacted layer of sand, gravel or crushed stone. At the ends of precast concrete slabs have protrusions and grooves for fixing their relative position when submerged installation, as well as speakers in the sides of the steel embedded parts for tight bolted connection of adjacent elements together when laying them on the ballast base (see SNiP 3.07.02-87 "Hydraulic marine and river transport facilities, as well as the book. Smirnova GN. and other authors Ports and port facilities" Chapter 22. "Slips" on str-446, 457, Ed. ASV 2003).

Similar characteristic closest analogue (prototype) with the claimed invention is the presence of ship-carrying trolley, which moves along nationaleconomy path, installed on precast concrete slabs with holes.

The disadvantage of the nearest analogue in the form of a hangar is the fact that the laying of precast concrete slabs on compacted ballast layer of sandy soil, gravel or crushed stone does not provide the stability and reliability of structures as ballast layer in the form of such soil is prone to erosion under the influence of storm waves, especially in the open coast.

The technical task of the invention is to create conditions for the construction of ship handling equipment in the open coast on rocky or half-rock underwater coastal slope, increasing its stability and reliability when operating in the open coast.

The problem is solved with a new set of essential features, allowing us to obtain new and useful technical result due to the fact that construction including ship-carrying path, ship-carrying cart and precast concrete slabs with holes, edge sides and the mounting loops (signs, similar to the closest tax), equipped with a metal rack to place and move around the precast concrete slabs during construction, and the metal rack is made in the form of a metallic frame including bearing metal b is the CTL with fixed restraint straps, which form an inclined guide the upper zone with the high and low sides, and the lofty side inclined guide the upper belt of a metal rack installed close to the coastal escarpment and the lower side of the inclined upper guide belt is installed with an emphasis on underwater coastal slope, and at its end is rigidly fixed bearing end block with the front wall, with an inclined upper guide belt metal rack is parallel to the sloping ground ship-carrying path. To the lower side of each precast slabs fixed l-shaped brackets for engagement of the latter with restraint straps two steel beams inclined upper belt of a metal rack in the process of construction. The length of the inclined upper guide belt set corresponding to the length of the inclined platform ship-carrying path. The length of the precast slabs set equal to the width of salvaging structures.

The method of construction lifting precast-monolithic structures by installing precast concrete slabs differs from the closest analogue to the fact that the original pre-cleared rock or half-rock bottom coastal waters close to the coast is at the ledge in the design position of the constructions set a metal rack with terminal block after that, two supporting metal beams elevated side inclined guide the upper belt of a metal rack set (placed) first team reinforced concrete slab and move it on two supporting metal beams sloping down, with the beginning of its movement of l-shaped brackets injected into engagement with the retaining straps and the first team of a reinforced concrete slab next move obliquely downward to the lower end side of the inclined guide the upper belt of a metal rack with a tight fit her front side longitudinal faces by the end wall bearing end block, then into the hole of the first concrete slab install interesuushie reinforcing bars and through these same holes serves the concrete mixture, filling her space under the first concrete slab, limited on the sides of the formwork, until filling is complete, at the end of the concreting process space under the first concrete slab and holes in the same process set (placed) on two supporting metal beams elevated side inclined guide the upper belt of a metal rack second team reinforced concrete slab, just move it on two bearing metal beam is tilted down, in the beginning of the movement of l-shaped brackets injected into engagement with the retaining straps and the second team of a reinforced concrete slab next move sloping down to a snug fit front lateral longitudinal face of the second concrete slab to the first concrete slab, and then in the hole in the second concrete slab install interesuushie reinforcing bars and through the same hole serves the concrete mixture, filling the space under the second concrete slab, limited on the sides of the formwork, until filling is complete, at the end of the process of the second monolithic concrete slabs in the same process sequence set for two bearing metal beams elevated side inclined guide the upper belt of a metal rack alternately following each team a reinforced concrete slab, just move sloping down, filled with the concrete mixture space under each regular concrete slab, to the last, to education after a single monolithic precast-monolithic reinforced concrete structures - shed.

In the presence of a horizontal vessel transportation path 6, the vessel transportation chamber 3 with the vessel 4 from the launching trolley 2 is moved to a self-propelled transport trolley 7, which moves it to the other end of the horizontal vessel transportation path 6. If there is a curvilinear section 10 on the horizontal vessel transportation path 6, the vessel transportation chamber 3 with the vessel 4 from the self-propelled transport trolley 7 is moved to an additional self-propelled transport trolley 11, on which it moves to the end of the curvilinear section 10, where it moves to the launching trolley 8 and descends to the level sufficient for the vessel 4 to come out of it to the open water area.

EFFECT: simplifying the design of the vessel transportation system and expanding its functional capabilities.
