Description

one

The invention relates to hydraulic construction, to devices for the preparation of underwater bases for the installation of hydraulic structures.

A device for underwater hydraulic works, in particular for concreting, is known, including a block formwork, a vertically moving pipe for laying concrete and a horizontal screen with vibrators l.

However, the device has insufficient accuracy in the work.

It is also known a device for the reclamation and lay-out of underwater bases for hydraulic structures, consisting of a floating body with a frame hinged on it, pipes for washing the soil, and a nozzle 2.

The disadvantage of it is that it is intended only for specific structures, pre-installed

Under water, for example, tunnel sections, the width of which is comparatively small. This device is not suitable for large structures of large area, for which a base previously planned with high precision is required.

The purpose of the invention is to increase the efficiency of the device.

The goal is achieved by the fact that the floating body is made up of sections equipped with piling apparatus, one of which has horizontal guides in which another movable section is installed with the possibility of movement, the movable section having a rotating device on which a frame made of parallel levers and planing site, on which is placed a nozzle for alluvial soil hinged to the lower part of the levers. Ha FIG. 1 shows the device, a general view; in fig. 2 - the same, side view; in fig. 3 - the same plan view; in fig. C - planning area, cut. The device consists of a main section 1 of the housing with guides 2 in which movement of the movable section 3 of the housing is possible. The main body of the hull 1 is equipped with piling devices 4 with bearing pads 5 ja and the movable section 3 of the hull has two piling devices 6 and a pivoting device 7 on which the frame is hinged, composed of two parallel levers 8. At the bottom of the frame is hingedly planed A platform 9 with a nozzle 10 for washing the soil and a discharge pipe 11. Before the beginning of the alluvium, the main section 1 is hung out on the pile machines C, and the mobile section 3 is fully extended forward along the guides 2 by means of winches. Then, the planning platform 9 is lowered to a predetermined depth and the soil feed in the form of pulp begins. The soil exits the nozzle 10 in the leveling platform 9 and zamulet space under the platform 9. As the circuit turns, the actuator of the rotator 7 is turned on and the leveling platform 9 moves along the radius, leaving behind it a washed soil strip. In the extreme position, the movable section 3 moves from inside the main section 1 along the guides 2 by the amount of the band to be washed and the actuator of the rotator 7 is reversed. Further movement of the platform 9 is carried out in the opposite direction. This process lasts until the entire length of the guides 2 is used. After that, the main section 1 is rearranged. To do this, the piles of the devices 6 of the movable section 3 are punctured, and the piles of the devices 4 are raised and the main section 1 is winched to move the entire length guides 2. Then the piles of the apparatus 4 are lowered and the main section 1 is hung on them. At the same time, the height of the posting should be determined by conventional geodetic devices (for example, a laser beam). Then the whole cycle is repeated. Hanging section 1 is necessary in order to impart stability to the whole device, especially in the presence of waves. The proposed device allows for the reclamation and layout of underwater areas with a sufficiently high accuracy of installation of large hydraulic structures, for example, by a floating method. In addition, the device can be used to lay a given layer of filter material on the bottom of the reservoirs. By eliminating a large amount of diving work, a significant economic effect can be obtained. Apparatus of the invention for the inoculation and lay-out of underwater bases for hydraulic structures consisting of a floating body, with a frame hinged on it, a pipe for collecting soil and a nozzle, characterized in that, in order to increase the efficiency of the device, the floating body is made integral of the section equipped with piling apparatus, one of which has horizontal guides, in which another movable section is mounted so that it can move, and the movable section has a rotary stroystvo on which the frame is made of a parallel levers and the planning fields, at which the nozzle taken for namyba ground, hinged to the bottom of the levers.
