The utility model discloses a half grout sleeve structure of grout formula in advance, with grout material prefabrication in a thick liquids section of thick bamboo, when constructing half grout sleeve structure of grout formula in advance, only need will treat in the connecting reinforcement disect insertion thick liquids section of thick bamboo can. Compared with the traditional grouting sleeve construction process, the grouting operation is omitted, the grouting sleeve construction process is simplified, and the grouting sleeve construction efficiency is improved.
Furthermore, among the half grout sleeve structure of grout in advance, still include the steel bar of treating the connection that the surface set up the catalyst layer. Before the steel bars to be connected are inserted into the slurry barrel, a catalyst can be coated on the surfaces of the steel bars to be connected. After the reinforcing bar to be connected is inserted into the grout material cylinder, the catalyst can accelerate the solidification of grouting material, improves the efficiency of construction.
Furthermore, in the pre-grouting type semi-grouting sleeve structure, the sleeve opening sealing sleeve is a one-way sealing sleeve. The unidirectional nozzle cuff can be opened from the exterior of the slurry barrel. The arrangement of the one-way sleeve can ensure that grouting materials cannot flow out of the slurry barrel before construction, and can facilitate the insertion of the steel bars to be connected during construction.
Furthermore, in the pre-grouting type semi-grouting sleeve structure, the steel bar connector is provided with a groove. The cross section of the groove is matched with the cross section of the internal steel bar of the prefabricated part, so that the steel bar connector and the internal steel bar of the prefabricated part can be conveniently connected together.
