Problems solved by technology

[0003] The existing commonly used underwater grouting materials include clay, cement and traditional concrete. Because the traditional grouting materials are highly dispersed when exposed to water, they are easy to be washed away, and cannot reach the pore positions that need to be filled well, so as to fully fill the cavity of the stone gap. Difficult to achieve the desired effect

Abstract

The invention discloses a material and a construction method for the ocean engineering rubble throwing foundation grouting consolidation. The grouting material comprises a gel material, cellulose, a high-performance water reducing agent, a flocculating agent, an inert powder, calcium chloride, starch glue, seaweed gel, a microbial composite inoculant, and calcium carbonate. The grouting construction method comprises the following steps: current situation investigation, field formula test, measurement and positioning, drilling, hole-cleaning, slurry preparation, upward grouting from the bottomof a hole to a designed position, and hole-sealing. The grouting material provided by the invention can effectively solve the problem of underwater grouting, can work with water, and avoids the problem that the common slurry is dispersed when meeting water or is washed away by water flow, and the like.

Description

technical field [0001] The invention relates to the field of pouring, in particular to a material and a construction method for pouring and consolidating foundations of rubble throwing in marine engineering. Background technique [0002] With the development needs, human beings are using more and more offshore areas to expand space resources, and the corresponding offshore engineering technology is developing rapidly, one of which is underwater engineering construction. Because caissons and rubble throwing are the most simple and convenient methods for underwater foundation construction, artificial islands, docks and other foundation constructions often use this method. As people's ecological awareness gradually increases, large-scale rubble mining is limited, and more Small rubble and other fine aggregates are easy to flow away with the sea water, causing the foundation to be hollowed out, making the foundation unstable, and the caisson sinking and cracking. At this time, i...
