(接续)桩端压力注浆桩施工桩端压力注浆桩施工程序成孔视地层土质和地下水位情况采用合适的成孔方法(干作业法、泥浆护壁法、套管护壁法及冲击钻成孔法)。放钢筋笼及桩端压力注浆装置在多数桩端压力注浆工法中,压力注浆装置都附着在钢筋笼上,两者同步放入孔内;有的桩端压力注浆工法是在钢筋笼放人孔内后再将压力注浆装置放人至桩孔底部。灌注混凝土按常规方法灌注混凝土。
(Continued) Pile Pressure Grouting Pile Construction Pile Tip Pressure Grouting Pile Construction Procedure Into the soil and groundwater level of the formation formation stratum Using the appropriate method of hole formation (dry work method, mud retaining wall method, casing wall protection method and impact drill Hole method). Put the steel cage and pile pressure grouting device In most pile pressure grouting method, the pressure grouting devices are attached to the steel cage, the two simultaneously into the hole; some pile pressure grouting method is in the steel After the cage is released into the hole, the pressure grouting device is released to the bottom of the pile hole. Pour concrete according to the conventional method of pouring concrete.
