される装置に関する。[Detailed Description of the Invention] Purpose of the Invention (Industrial Field of Application) The present invention relates to a device for repairing areas of gas-liquid fluctuations and liquid splash zones caused by tidal level fluctuations on the water side surface of steel sheet piles. More specifically, the present invention relates to a device used to form a working space below the water surface when repairing steel sheet piles constituting a quay near the water surface.

る。(Prior art) Corrosion protection for quay walls using steel sheet piles is generally performed by electrolytic corrosion for the parts that contact the soil and submerged parts below the lowest tide level, and for areas where gas and liquid fluctuate from the lowest tide level to the highest tide level. Currently, the aerial parts above the highest water level are left with the anti-corrosion coating applied at the time of new construction. As a result, corrosion protection has progressed particularly markedly in areas where air and liquid fluctuate and in splash zones that are hit by wave spray, and in some areas, sediment from the quay has flowed into the water due to openings, causing the bank to lose its function. ing.

望ましい。 In recent years, in order to solve this problem, a construction method has been developed in which the surface of steel sheet piles is coated with a highly reliable anti-corrosion coating in advance at a factory, and then poured on-site. This coating has excellent corrosion resistance, and if possible, it is desirable to use it on existing steel sheet pile quay walls.

装置が望まれる。(Problem that the invention aims to solve) However, in the past, repair work for areas with gas-liquid fluctuations and splash zones was generally carried out by setting up scaffolding suspended from above, or by being carried out underwater by divers. Both methods are affected by tidal level fluctuations and are exposed to spray during work, so
The drawback was that it was not possible to obtain a repair environment reliable enough to apply the anti-corrosion coating. Therefore,
A device is desired that can isolate the work surface from fluctuating liquid levels and splashes until the coating is completely dry and in intimate contact with the sheet pile.

The purpose is to provide equipment to ensure that

いる。 Structure of the invention (means for solving the problem) In order to achieve the above object, the present invention has a structure that is opened at the top and one of the sides to form a working space between it and the sheet pile, and is placed on the quay. While the frame is rotatably supported on a support stand to generate a moment that is pressed toward the sheet pile, an elastic tube seal is provided on the periphery of the frame that comes into contact with the sheet pile, and a seal is provided between the sheet pile and the skeleton. This creates a watertight work space below the water surface that is separated from the surrounding water.

The body 1 is pressed against the surface of the steel sheet pile 7 by a couple of forces rotating clockwise in FIG. Thereafter, a working space is formed inside the body 1 by removing water from the body 1 using a pump or the like. In this case, as the water inside the body 1 is removed, the degree of adhesion between the body 1 and the steel sheet piles 7 is strengthened due to the difference in water level with the outside.

ことができる。 Structure of the Device As is clear from the above description, the device for repairing the gas-liquid fluctuating parts of steel sheet piles according to the present invention has a main body that is open at the top and one of the sides and forms a work space between it and the sheet piles. is rotatably supported on a support stand placed on the quay so that a moment is generated that presses it toward the sheet pile.An elastic tube seal is installed on the periphery of the skeleton where it comes into contact with the sheet pile. Since a watertight working space is created below the water surface that is partitioned off from the surrounding water, repair work for corrosion in the gas-liquid fluctuating parts of existing steel sheet piles can be done in the same way as work on land. An air space can be easily formed, a highly reliable coating method that has not been available up to now can be employed, and the efficiency of repair work can be significantly improved.
