the pre-grouting type full grouting sleeve structure comprises a grout material barrel, wherein a grout overflow hole is formed in the barrel wall of the grout material barrel, barrel opening sealing sleeves are arranged at barrel opening parts at two ends of the grout material barrel respectively, a grout overflow opening sealing sleeve is arranged at a grout overflow opening part of the grout overflow hole, and grouting materials are filled in the grout material barrel.
The utility model discloses a grout sleeve structure entirely of formula of grouting in advance, with grout material prefabrication in a thick liquids section of thick bamboo, when being under construction to grout sleeve structure entirely of 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 full 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 full 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, among the full grout sleeve structure of grout formula in advance, in order to facilitate the overflow of grout material, the grout outlet sets up in the middle part of thick liquid feed cylinder.
