Miniature steel pipe grouting construction technology
The invention relates to the field of building pile foundations, and particularly discloses a micro steel pipe grouting construction process which comprises the following steps: S1, geological investigation: carrying out geological investigation on a to-be-constructed area, and selecting a proper pile descending area; s2, pile arrangement design is carried out, and the proper pile position, pile depth and pile arrangement number are designed in the lower pile area according to the bearing capacity requirement of the design requirement; s3, drilling is conducted, specifically, drilling is conducted at the pile position to the designed elevation to form a pile hole; s4, pipe insertion: inserting a steel pipe body into the pile hole to the bottom of the pile hole; s5, filler compaction is conducted, specifically, the steel pipe body is filled with filler in batches, and the filler is compacted to form a compaction head; and S6, grouting is conducted, specifically, a grouting pipe is arranged in the steel pipe body, a gap between the steel pipe body and the grouting pipe is sealed, and cement paste is injected into the steel pipe body to the designed elevation. The method has the effects that the single-pile bearing capacity is high, and the requirement for grouting pressure is low.
本申请涉及建筑桩基领域，具体公开了一种微型钢管注浆施工工艺，其包括以下步骤：S1.地质勘察，对待施工地区进行地质勘察，选定合适的下桩区域；S2.布桩设计，根据设计要求承载力要求在下桩区域设计合适的桩位、桩深和布桩数量；S3.钻孔，在桩位处钻孔至设计标高形成桩孔；S4.插管，在桩孔中插入钢管体至桩孔底部；S5.填料压实，向钢管体内分次填入填料，并将填料压实形成挤密头；S6.注浆，在钢管体中下注浆管，密封钢管体与注浆管间的间隙，并向钢管体中注入水泥浆至设计标高。本申请具有单桩承载力高且对注浆压力要求较小的效果。
