The invention discloses a
grout runout treatment method for planting of a precast
pile in a
rubble layer. Through the
grout runout treatment method, the
grout runout problem occurring to the precast
pile in the
rubble layer is solved. A protective
barrel is used during hole forming, thus stratum stability during hole forming is ensured, hole collapse is not liable to occur, after poured grout is poured in, conditions can be provided for initial
setting time of the grout, and the effect that before initial setting of the grout, the
rubble layer containing water does not collapse towards the inside of the hole is ensured. According to the technical scheme of the grout runout treatment method, the grout runout treatment method comprises the following steps that the precast
pile is made and is transported to a pile planting site; the hole position of the precast pile is determined, the precast pile is put into the pile hole after drilling, and the protective
barrel is put in the pile hole; the poured grout is made with a set ratio, and the grout is poured into the pile hole from bottom to top; the protective
barrel is clamped by a vibration hammer to be matched with a crawler crane and is taken out, and grouting is completed; after grout is solidified for the set time,
coring observation is conducted on the grout, and whether the grout runs off is judged; and if yes, holes are formed in the two sides of the pile hole, grout is sprayed, and the grout is reinforced.
