In-depth type funnel grouting sleeve grout supplementing method

Abstract

The invention relates to an in-depth type funnel grouting sleeve slurry supplementing method and belongs to the technical field of grouting sleeve slurry supplementing. The in-depth type funnel grouting sleeve slurry supplementing method comprises the following steps of S1, preparing a slurry supplementing agent, firstly preparing the slurry supplementing agent before slurry supplementing, adding the slurry supplementing agent with small particles, low viscosity and strong fluidity into the slurry supplementing agent, and placing the slurry supplementing agent at a construction site for later use after the slurry supplementing agent is prepared; S2, a grout supplementing device being installed, specifically, the grout supplementing device being hung at a high position, and the diameter of an outlet of a grout supplementing pipe in the grout supplementing device being smaller than that of a grout outlet of the grouting sleeve; and S3, slurry supplementing being conducted, specifically, the prepared slurry supplementing material being poured into a funnel at a top end of a slurry supplementing device, a switch arranged on a slurry supplementing pipe being turned on, then the slurry supplementing pipe being inserted into the grouting sleeve through a slurry outlet, and the slurry supplementing material flowing into the grouting sleeve through the fluidity of the slurry supplementing material. According to the secondary slurry supplementing device, a technical problem that in the secondary slurry supplementing process, due to the air exhaust problem, cavities still exist in the sleeve can be solved.

Description

technical field [0001] The present application relates to the field of grout replenishment for grouting sleeves, in particular to a grout replenishment method for deep funnel grouting sleeves. Background technique [0002] The prefabricated structure is one of the key structural forms in the current process of housing industrialization in my country. It has the advantages of high efficiency, low energy consumption and green environmental protection, and meets the current economic and social development requirements. The structural integrity of prefabricated buildings is one of the most important measures of the durability of prefabricated buildings, and one of the key points of its technology lies in the way vertical components are connected. At present, steel sleeve connection technology is generally used in the connection of vertical components in prefabricated buildings. This connection technology can not only make up for the shortcomings of traditional connection methods...
