新型压力注浆灌注桩（ＧＢＰ桩）施工方法除与一般压力注浆桩相同外，还多一道注浆工序，即不但对桩端土注浆，还对桩周土注浆，故其注浆效果明显优于桩端、桩侧分别注浆的桩。ＧＢＰ桩在减少沉降量的同时，单桩承载力高于一般灌注桩和其它类型的压力注浆桩，它还具有适应土质范围广（除流沙、淤泥外），施工场地不受限制，施工方法灵活、注浆设备简单、便于普及等特点，同时也是解决灌注桩普遍存在桩端虚土等施工质量问题的有效途径。 In addition to the same pressure grouting pile as the general pressure grouting pile, the construction method of the new type of pressure grouting and pouring pile (GBP pile) adds another grouting process, that is, the grouting The effect is obviously better than the pile end, pile side respectively grouting pile. In addition to settling capacity, GBP pile has higher bearing capacity than ordinary bored piles and other types of pressure grouting pile. It also has a wide range of adaptable soil (except for quicksand and silt) and no restriction on the construction site. The construction method Flexible, simple grouting equipment, easy to popularize and so on. It is also an effective way to solve the construction quality problem of cast-in-situ pile-end soil and so on.
