SU1689563A1 - Method for erection of large-size object in water basin - Google Patents

Description

The invention relates to the construction, in particular to the construction of large objects or their enlarged blocks in the waters of the reservoir, followed by transportation to the place of operation. The aim of the invention is to reduce the volume of hydraulic works and simplify transportation of the object in the channels. The method is as follows. Vplot2

Two parallel transverse removable (inventory) bridges are installed perpendicularly to berth 1, and Parallel 6 - a permanent bar 6, using the berth wall of berth 1 as a fixed bridges. Thus, close to berth 1, an enclosed portion of the water area is formed, which is drained. At the bottom level of the fenced-off area, a construction site is formed and an object is mounted on it with a waterproof part of it. As the waterproofing part of the object is erected, the enclosed area is filled with water to the water level in the water area, followed by the installation of the rest of the object. By zazerneni assembly of the entire object of time. The 5 jumpers are dismantled, and pontoons 8 and 7 are attached to the object, the latter being attached to the walls ι of the object, which are perpendicular _{to the} base wall, and positioning them along quay 1. Then, using pontoons 7 and 8, the object is afloat transported to the place of operation. 7 il.

The invention relates to the construction, in particular to the construction and transportation of heavy loads and objects.

The aim of the invention is to reduce the volume of hydraulic works and simplify transportation of the object in the channels.

FIG. 1 shows a section of the water area fenced off by bridges with a construction site; a plan; in fig. 2 shows section A-A in FIG. one; in fig. 3 - the foundation of the object erected on the construction site; in fig. 4 - object erected on the site with bridges removed; in fig. 5 - an object on the site with pontoons attached to it; in fig. 6 - an object with afloat pontoons in a transport position; in fig. 7 - the same plan.

A large object with a high specific gravity, erected at berth 1, contains a waterproof base 2 and is erected at the construction site 3, fenced off from the rest of the water area by temporary bridges 4 and 5 and a permanent bridge 6 used for the erection period. The berth wall of berth 1 is used as a fixed bridge. First, temporary bridges 4 and 5 and a permanent bridge 6 enclose a section of the water area adjacent to berth 1, and the bridges are located a short distance from the place reserved for the construction of the object. The fenced area is dried, a construction site 3 is formed at the bottom level, on which a waterproof base 2 is erected. As the base 2 is erected, the partitioned part with the construction site is gradually filled with water to the water level in the water area, after which temporary bridges 4 and 5 are removed, the erection the object is continued until its completion, and the submerged pontoons 7 and 8 are brought and attached to the walls of the object, perpendicular to the mooring wall, and the pontoons are placed along berth 1. Thereafter ontony 7 and drain 8, emerges from the platform 3 with pontoons object 7 and 8 and the output

between berth 1 and lintel 6.

Formation of a construction site at the bottom level close to the pier reduces the area and height of the site, which reduces the amount of building materials and the volume of hydraulic works.

The construction of jumpers at a short distance from the construction site reduces the area of the section fenced off with jumpers and the total length of the jumpers, which reduces the volume of hydraulic works.

The use of the quay wall as a stationary jumper reduces the amount of hydraulic work associated with the removal of jumpers before connecting the pontoons to the object.

The gradual filling of the enclosed area of water with water to the water level in the water area, produced as the construction of the waterproof base of the object is erected, reduces the amount of work to eliminate water filtration through bridges, and also reduces the quality requirements for jumpers, which reduces the volume of hydraulic works.

Attaching the pontoons to the walls of the object, perpendicular to the pier, and the location of the pontoons along the pier, with the result that the pontoons together with the object form a floating structure stretched in length, reduces the draft of the object without increasing its width, and transport it not only by sea, but and in the channels.

Removal of the structure between the berth and the permanent jumper allows the permanent jumper to be positioned at a short distance from the object, which reduces the size of the fenced-off portion of the water area and reduces the complexity of hydraulic works.

This embodiment of the method significantly reduces the size of the enclosed area of water, reduces the complexity of hydraulic works and provides the ability to transport the object in the channels, which reduces the cost of erection and reduce the cost of transporting the object from the construction site to the place of operation by reducing the length of the transportation route.

Claims (1)

Claim method of construction of large object in the water area of the reservoir, including installation in the water area on the side of the berthing wall of bridges, drainage of the fenced off area of the water area where the bottom level forms the construction site, installation of the object, filling the fenced area with water, dismantling the bridges and removing the object from the fenced area afloat by pontoons, characterized in that, in order to reduce the volume of hydrotechnical works and simplify the transportation of the object in the canals, the formation of the fenced off portion of the water area and the construction site ki carry out close to the berth five 1689563 6 the wall, using it as a stationary lintel, and filling the enclosed area with water is carried out to the water level in the water area as the waterproof part of the object is erected with the subsequent installation of its remaining part and joining to it after dismantling the jumpers of the pontoons, while the latter are connected to the object walls perpendicular to the mooring wall, and the pontoons are placed along the pier. g FIG L 1689563 FIG. eight
