Description

PL 69 516 Y1 2 Description of the design The subject of the utility model is a device for the renovation of damaged supports and the barrier of a steel anti-spill barrier in the underwater zone in air-dry conditions. During normal operation, hydrotechnical structures are subject to various damages, which are caused by changing meteorological and hydrodynamic conditions, corrosion damage, as well as mechanical damage caused by floating objects. Any damage that occurs requires repairs that are performed by persons equipped with swimming or diving equipment. Repairing these damages causes considerable difficulties during the execution with the use of known devices. From the patent description PL-200560 there are known devices for the repair of a hydrotechnical structure, especially a pile, in the form of an open-top chamber, which is formed of separate sections with walls perpendicular to the bottom. In the bottom of the chamber there is a hole with a circumferential sealing flange to fix the device on the renovated structure. The device according to the invention is characterized by the fact that it consists of four congruent to each other open at the two sides quarter cells. The bottom of each square chamber has the shape of a rectangle with a square section. A semicircular cut is made in the shorter wall of each square chamber. Vertical contact strips with through holes for screw connections are permanently attached to the two vertical outer edges of each quarter chamber. A quarter-leaf contact strip is permanently attached to the square-shaped edges of each chamber. A semicircular contact strip is permanently attached to each semicircular edge. Moreover, a ballast tank is attached to each of the shorter walls of the quarter chamber. All contact strips are provided with layers of sealing material. According to the utility model, the device is simple to manufacture and easy to operate, and it facilitates the repair of damaged supports and screens of the steel anti-spill barrier in the underwater zone. The utility pattern is explained in more detail in the drawing, in which Fig. 1 shows an axonometric view of one of the quadrilateral cells, and Fig. 2 shows the entire device. The device consists of four congruent quadrilateral chambers A, B, C, D open on two sides. The bottom of each quarter chamber A, B, C, D has the form of a rectangle with a quarter-circular segment. A semicircular section is made in the shorter wall of each quarter chamber. Vertical contact strips 1 for bolted connections with through holes are permanently attached to the two vertical outer edges of each quarter-chamber chamber. The semicircular contact strip 3 is permanently attached to the side semicircular edges. Moreover, a ballast tank 5 is attached to each shorter wall of the quadruple chamber A, B, C, D. Sealing material layers are placed on the contact strips 1, 2, 3. To the upper surface of each ballast tank 5, eyelets 6 are attached. In the eyelets 6, catch elements 7 in the form of turnbuckles are mounted, which are used to fasten the device to the renovated steel dam. The A, B, C, D borehole chambers are positioned in this way at the renovated steel dam in order to create a perimeter working chamber. The vertical contact strips 1 are screwed together and sealed with a sealing material. Also the sealing between the structure of the renovated steel dam and the semicircular contact strips 3 and the square-shaped contact strips 2 is achieved with the help of a caulking material, which is applied by divers. The stability of the working chamber is achieved by fitting the turnbuckles 7 as water is pumped out of it. PL PL
