Pile bottom grouting device and use method thereof
The invention discloses a pile bottom grouting device and a use method thereof. The pile bottom grouting device comprises a cone head, a grouting pipe and a rubber non-return sleeve. The cone head isfixed to the bottom end of the grouting pipe, slurry through holes are evenly distributed in the two sides of the bottom of the grouting pipe, the pipe section, provided with the slurry through holes,of the grouting pipe is a grouting section, the rubber non-return sleeve wraps the grouting section, the inner wall of the rubber non-return sleeve covers the surfaces of the slurry through holes, and the upper end and the lower end of the rubber non-return sleeve are fixed to the grouting pipe through fastening devices. The use method of the pile bottom grouting device includes the steps that the position of the grouting pipe is adjusted, the grouting pipe is fixed, a reinforcement cage is hung, concrete is poured, and pile body soil mass is reinforced. According to the device, the poured concrete and the grouting pipe are separated through the rubber non-return sleeve, slurry cannot be injected into the grouting pipe during pile body concrete pouring, the slurry cannot flow back duringgrouting, the smoothness of following slurry pressing is guaranteed, and the problems that during pile end grouting, the grouting pipe is easily blocked, the grouting amount does not meet the requirements, and the grouting pressure is small are solved.
本发明公开了一种桩底注浆装置及其使用方法，包括锥头、注浆管和橡胶止逆套，锥头固定于注浆管的底端，注浆管的底部两侧均布有透浆孔，注浆管上开有透浆孔的管段为注浆段，橡胶止逆套包裹于注浆段上且橡胶止逆套的内壁蒙覆于透浆孔表面，橡胶止逆套的上、下两端通过紧箍装置固定于注浆管上；其使用包括调整注浆管的位置、固定注浆管、吊放钢筋笼、浇筑混凝土、桩体土体加固的步骤。本发明提供了装置利用橡胶止逆套分隔开浇筑的混凝土和注浆管，在进行桩身混凝土浇注时浆液不会灌入注浆管内，注浆时浆液也不会回流，为后续压浆的顺畅提供保障，解决桩端注浆时注浆管容易堵塞、注浆量到不达要求、注浆压力小的问题。
