Изобретение относитс к судоремонту , а именно к способам расширени понтонного плавучего дока на плаву.The invention relates to ship repair, in particular to methods for expanding a pontoon floating dock afloat.

Известен способ расширени понтонного плавучего дока, при котором плавучий док спускают на воду, отдел ют половину понтона, вставл ют дополнительную секцию и соедин ют со второй половиной понтона l Недостатком указанного способа вл етс длительность и сложность расширени понтонного дока.A known method for expanding a pontoon floating dock in which a floating dock is launched, separating half of the pontoon, inserting an additional section and connecting it with the second half of the pontoon. The disadvantage of this method is the length and complexity of the expansion of the pontoon dock.

Наиболее близким к предлагаемому вл етс способ расширени понтонного плавучего дока на плаву путем приварки боковин наделок к понтонам перемещени башен и последующего их креплени к боковым наделкам 2. , Недостатком данного способа, применительно к понтонным докам, имеющим неразрезные башки, вл етс то, что членение башен на секции и последующее их соединение вл ютс весьмаThe closest to the present invention is a method of expanding a pontoon floating dock afloat by welding the sidewalls of the attachments to the pontoons of moving the towers and their subsequent attachment to the side fixtures 2. The disadvantage of this method with respect to pontoon docks having continuous heads is that the towers on the section and their subsequent connection are quite

трудоемкими и сопровождаетс заменой большого количества электрических кабелей и трубопроводов. Все это приводит к высокой трудоемкости работ по расширению понтонных доков и к длительному выводу их из стро .labor intensive and accompanied by the replacement of a large number of electrical cables and pipelines. All this leads to high labor-intensive work on the expansion of pontoon docks and to their lengthy withdrawal from construction.

Цель изобретени - уменьшение труде емк ости,The purpose of the invention is to reduce labor capacity,

Указанна цель достигаетс тем., что башни перемещают вместе с половинным числом понтонов, которые предварительно отсоедин ют через один каждый от одной из башен.This goal is achieved by moving the towers together with half the number of pontoons that are previously disconnected one after the other from one of the towers.

Кроме того, перед перемещением башен дока в понтоны принимают балласт .In addition, before moving the towers of the dock in the pontoons take ballast.

На фиг. 1 показан план дока с приваренными наделками; на фиг.2 - часть дока с одной башней, поперечное сечение .FIG. 1 shows the dock plan with welded fittings; figure 2 - part of the dock with one tower, the cross section.

Claims

The pontoon floating dock consists of identical pontoons 1 and 2, which are attached to the tower m 3 and 4 by means of flange connections 5. When the dock is expanded, pontoons 1 and 2 are welded on side fittings 6 with flanges 5 mounted on them, and to odd pontoons 1 they are welded from the side of the tower 3, and to the even pontoons 2 from the side of the tower 4. Then flange connections 5 of odd pontoons 1 with tower 3 are given, and flange connections of even pontoons are delivered by the 2nd tower 4. Thereafter, pontoons 1 and 2 are received ballast to detach forming with L -shaped portions dock from one another and these portions are moved by the amount of expansion dock. The divorced parts of the dock are interconnected, and the fittings of 6 pontoons 1 are fastened to tower 3, and the fittings of 6 pontoons 2 by tower 4 using squares of flange joints 5. Other options for welding the accessories to pontoons are possible, depending on the design of pontoons, for example, welding of accessories to all pontoons from the side of one tower or welding of accessories to all pontoons on both sides. In these cases, the specific technological sequence of moving the towers changes. 64 The effectiveness of the proposed method increases with increasing size of the expandable dock. Invention 1. A method for expanding a pontoon floating dock afloat by welding side attachments to pontoons, moving towers and their subsequent ones. fastenings to the side constructions, characterized in that, in order to reduce the labor intensity of the work, the towers move along with half the number of pontoons, which are previously disconnected through one each from one of the towers. 2, the method according to claim 1, and I differ from the fact that before moving the dock towers to the pontoons they take ballast.
