Construction method of offshore tide storage bottom sealing concrete

Abstract

The invention discloses a construction method of offshore tide storage bottom sealing concrete. The construction method specifically comprises the following steps of: pouring bearing platform bottom sealing concrete in two layers during rising tide, namely when the elevation of bearing platform bottom sealing concrete is higher than water surface; using a duct pouring underwater concrete construction process for the concrete layer of which the elevation of the bearing platform bottom sealing concrete is lower than the water surface; and after the strength of the concrete of the pouring layer of which the elevation is higher than the water surface reaches demands and ebb tide, using a dry pouring construction process for the concrete layer of which the elevation of the bearing platform bottom sealing concrete is higher than the water surface. According to the actual conditions of tide, the technical problem of influence of tide on offshore bottom sealing concrete construction is effectively solved by the construction process that the underwater tide storage and dry construction are combined with bottom sealing concrete layered pouring; the construction is easy, convenient and safe, the construction period is good and the effect is good; the construction quality of the bottom sealing concrete is effectively guaranteed; favorable conditions are created for bearing platform dry construction; and the construction method has wide application prospect and excellent reference value for similar projects.

Description

Technical field [0001] The invention relates to the technical field of bridge construction, in particular to a construction method for sea moisture storage and bottom sealing concrete. Background technique [0002] At present, when the concrete elevation of the bottom seal of the offshore platform is below the water surface, the construction technology of underwater concrete pouring is adopted. However, in reality, the height of the water surface fluctuates due to the fluctuation of the sea tide, which makes the concrete elevation of the bottom cap of the platform fluctuate relative to the water surface. When the coagulation elevation of the bottom cap of the cap is within the range of the tide fluctuation When using concrete for the back cover, the cementitious material is easy to lose with the seawater during the rise and fall of the tide, which seriously affects the internal quality of the back cover concrete. Summary of the invention [0003] The purpose of the present invent...

Problems solved by technology

However, in practice, due to the influence of the tide at sea, the height of the water surface fluctuates to a certain extent, so that the concrete elevation of the cap bottom cover also fluctuates relative to the water surface. When the concrete elevation of the cap bottom cover is within the range of tidal fluctuations When the back cover concrete is used for construction, the cementitious material is easy to be lost with the seawater during the tide fluctuation process, which seriously affects the internal quality of the back cover concrete.
