Research of micro-pressure grouting construction technology for precast vertical member reinforcement sleeve grouting connection
Reinforcement sleeve grouting connection is one of the main connection methods for precast reinforced concrete structure. The plumpness of sleeve grouting is the key to the connection of sleeve grouting. To solve the problem that the sleeve grouting is not full, the author improved the warehouse division method, and researched a micro-pressure grouting construction method that can ensure 100% full grouting of each sleeve even without compartments. In this paper, the basic principle of micro-pressure grouting is described, the technological process is put forward, the experiment of water injection before grouting is carried out, and the micro-pressure grouting method is applied to many practical projects, among which the negative pressure grouting method can effectively improve the quality of grout layer bonding surface. The paper predicts that the micro-pressure grouting technology will also bring new changes to the form and construction technology of prefabricated components in the future.
