Laying method of epoxy resin layer for vertical support structure of independent tank

Abstract

The invention provides a method for laying an epoxy resin layer of a vertical bearing structure of an independent liquid tank. The method mainly comprises the steps: a plurality of jacking bolts are screwed into ends of the jacking bolts through corresponding threaded holes in a lower panel to be higher than the lower panel so as to reach the theoretical thickness of the epoxy resin layer; a stainless steel plate is placed at the ends of the jacking bolts, and the upper surface of the stainless steel plate is made to be flushed with a mounting locating line by adjusting the jacking bolts; a supporting adjusting device is arranged, and the independent liquid tank is lifted to an upper panel to be in contact with the supporting adjusting device; the supporting adjusting device is adjusted to enable layer wood to be tightly attached to the stainless steel plate; and through laying holes in the lower panel, liquid-state epoxy resin is injected into a cavity, and the liquid-state epoxy resin is stopped from being injected into the cavity until the liquid-state epoxy resin flows out of the edge of the stainless steel plate. According to the method for laying the epoxy resin layer, the method is not limited by the construction height and narrow space, and the laying thickness can be adjusted according to the actual construction precision; and it can be ensured that the layer wood can be tightly attached to the stainless steel plate.

Description

technical field [0001] The invention relates to a method for laying an epoxy resin layer, in particular to a method for laying an epoxy resin layer for a vertical support structure of an independent liquid tank. Background technique [0002] A vertical support structure 3 is provided between the tank bottom plate 1 and the hull bottom 2 of the diamond-shaped independent tank of the liquefied gas carrier (see figure 1 ), the vertical support structure 3 is composed of an upper support part 31 welded with the tank bottom plate 1 of the independent tank and a lower support part 32 welded with the hull bottom 2 at the bottom. If the low temperature inside the independent liquid tank is directly transferred to the inner bottom 2 of the hull, the low temperature transfer between the liquid tank and the hull will cause the hull structure temperature to be too low, resulting in the danger of low-temperature brittle fracture of the metal. To avoid this danger Laminated wood 33 and e...

Problems solved by technology

Because the distance between the tank bottom plate 1 and the hull bottom 2 is very small, the laying construction height is limited, and the space is narrow, it is almost impossible to realize the artificial laying method; the laminated wood 33 and the stainless steel plate 34 must be mutually For tight fit, it is also necessary to ensure that there are no air bubbles between the laminated wood 33 and the stainless steel plate 34, and the thickness of the epoxy resin layer 36 is thin, the area is large, and it is flat in a large area. Obviously, the application of the cement-like epoxy resin layer Laying method can not meet the actual requirements
