Side constraint grouting pile for soft soil stratum and construction method of side constraint grouting pile
The invention relates to a side constraint grouting pile for a soft soil stratum and a construction method of the side constraint grouting pile. The grouting pile comprises a steel pipe pile serving as a grouting pipeline and a grouting expansion consolidation block mass arranged on the lower portion of the steel pipe pile. The small end bearing force of a pile foundation in a soft soil layer is remarkably increased through the structure and the method, grouting expansion is conducted at the pile bottom to form a stable consolidated block mass, the needed pile length or pile diameter is reduced, a pile body has higher compression resistance and bearing performance, meanwhile, larger pulling resistance can be provided, the functionality of the pile body is enhanced, the use range of the pile body is widened, and the construction cost is lowered. The engineering cost is further reduced, and the purposes of saving resources and reducing energy consumption are achieved.
本发明涉及一种用于软土地层的侧约束注浆桩及其施工方法，其中注浆桩包括：作为注浆管道的钢管桩和设置在钢管桩下部的注浆膨胀固结团块；将软土地层中桩基较小的端承力通过本发明结构及方法在桩底注浆膨胀形成稳定固结团块而显著增大，减小其所需桩长或桩径，使桩体具备更强的抗压承载性能，同时能提供出更大的抗拔力，增强桩体的功能性，拓宽其使用范围，进一步降低工程造价，达到节约资源、减少能耗的目的。
