Method of strengthening of the ice cover
(57) Abstract:The increased ice cover provide columns of ice blocks placed on top of each other. The blocks form from the package vertically installed ice plates and a horizontal plate, which is cut in the ice cover after installing it on ice and the freezing plates with each other and ice cover. The first block is dipped in the lane formed when cutting the horizontal plate. After education in Maine ice cover on it to form the next block. Each block is immersed to a depth at which its upper end is at the level of the bottom surface of the ice cover. 9 Il. The invention relates to the field of construction and for the efforts of the ice cover when performing the role of the support base.There is a method of amplification of the ice cover by cutting ice blocks, ice blocks translation in a vertical position with the natural cover and morgiana (ed.mon. USSR N 1181345, MKI E 02 IN 17/00, 1983).The disadvantage of this method is the significant complexity associated with the need to cut a large number of blocks, lifting, transportation, Ogre is a way to enhance the natural ice cover, which is provided by the formation of ice pillars of ice blocks with installing them on the bottom (U.S. patent N 4373836, MKI E 02 D 3/00, 1983).The disadvantage of this method is the complexity of the implementation, i.e., requires the manufacture of metal termonology with subsequent fixation on the bottom of the freezing unit, which reduces the effectiveness of the method.The objective of this invention is to provide an ice structures using natural conditions and resources.The technical result is to reduce the influence of the anisotropy of the ice, which is typical for ice structures that run the other way. The anisotropy of the ice these ice columns is reduced due to the fact that the columns are formed of vertically spaced blocks, numerossimi on these blocks in the horizontal plane. The claimed method are easily and quickly the ice column, operating reliably in conditions of the North.This technical result is achieved in that in the method of amplification of the ice cover by forming columns of ice blocks that sink to the bottom of the water area by placing them on each other, the column is formed from a package installed vertically ice plates and denom cover and freezing his plates with each other and ice cover, and the immersion of each unit produced in the lane formed by cutting the horizontal plate to a depth at which the top end of the block is at the level of the bottom surface of the ice cover and subsequent securing the block in position, and install the package each subsequent block is carried out in an ice cover formed in the main previous block.Compared with the prototype of the proposed set of characteristics and the sequence of their execution is new.Method of strengthening of the ice cover (its implementation) is shown in Fig.1-6, Fig.7 depicts a cut ice with the formation of the ice column, and Fig. 8 the design of the ice pier; Fig.9 an enhancement of the ice base oil rig.An example implementation of the method.On selected ice 1 cut blocks harvested pack 2 and set the butt on the ice cover 1 (Fig.1). Next produce marajuana blocks in package 2 between itself and the ice cover 1 with the formation of a monolithic structure (Fig.2). After that make cutting a slot 3 on the perimeter of the package 2 in ice cover 1 (Fig.3). Produce dive package 2 to a depth equal to the 4). Freeze the resulting lane 4 (Fig.5). After this operation is repeated (Fig.6).Examples of practical implementation of the method of amplification of the ice cover by forming columns of ice blocks shown in Fig.7-9.For the formation of the ice column at the selected ice, 1 cut through the ice cover 1 along the contour of the package units 2, smorodinnogo with ice cover 1. Dip package 2 blocks to a depth equal to the height of the package units 2 and the thickness of the ice cover 1 with the formation of lane 4 and is fixed. After freezing lane 4 operations repeat until the touch columns of the bottom of the reservoir.Icy dock built by organizing series of ice columns, consisting of packages of blocks 2, between which the ice cover 1 is amplified by immersing the cut package units 2 and subsequent marajuana. While the ice column, consisting of packages of blocks 2, tighten the anchors 5. To prevent thawing of the surface of ice sheet sprinkled with a heat insulating material 6.Presents also an enhancement of the ice cover 1 under construction rig 7. The increased ice cover 1 is produced by installing two or but cover 1 spread out the cloth 8 of spongy elastic material with their subsequent soaking and marajuana.Thus, the possibility of using this method in industry is shown in two examples. In addition, there are plenty of uses for this method of amplification of the ice cover.This method is easily implemented in the North without additional costs. 2 4 Method of strengthening of the ice cover by forming columns of ice blocks that sink to the bottom of the water area by placing them on each other, characterized in that the blocks form from the package vertically installed ice slabs and horizontal ice plate, which is cut in the ice cover along the contour of the package after installing it on the ice and the freezing of its plates to one another and ice cover, and the immersion of each unit produced in the lane formed by cutting the horizontal plate, the depth at which the top end of the block is at the level of the bottom surface of the ice cover, and subsequent recording unit in this position, and install the package each subsequent block is carried out in an ice cover formed in the main previous block.
SUBSTANCE: invention can be used in designing ramp and propulsion and steering gear and their hydraulic systems. Novelty in proposed water craft is that it is furnished with streamlined carrying frame for fastening devices of propulsion and steering complex installed in hull aft part and formed by two pairs of rigid longitudinal beams hinge secured by inner ends of aft sheet of hull in zone located under loading side coupled by flexible cross beams in each pair and support bar between pairs. Hydraulic heads of propulsors are hinge-mounted on outer ends of each pair of longitudinal beams, being secured on said beams to form additional cross tie between beams. Carrying frame is furnished with power hydraulic cylinders connected with hydraulic system and installed to control position of heads and loading side by turning carrying frame in aft sheet hinge joints. Body of each is provided with upper roller support, being rolling support for each hinged loading side at its opening, and lower platform being rigid base interacting with ground at resting of hinged loading side on head body in loading position of loading side. Novelty in hydraulic system of watercraft is that it is furnished, in additional to propulsor control hydraulic cylinders, with hydraulic cylinders for setting ramps, changing thrust vector, fixing loading side and locking carrying frame. Each hydraulic cylinder, including propulsor position control hydraulic cylinders, are supplied through parallel hydraulic lines connected with main line, with electric control in each line. Invention contains description of design peculiarities of each line providing required modes of operation of watercraft.
EFFECT: improved performance of watercraft and creating of hydraulic system providing required mode of operation of watercraft.
