Construction method for reinforcing complex stratum through grouting steel pipe piles
The invention relates to the technical field of constructional engineering, in particular to a construction method for reinforcing a complex stratum through grouting steel pipe piles. The constructionmethod comprises the following steps of (1) tamping a site, ensuring that the site is flat, and performing measuring and positioning; (2) using a drilling machine for drilling at the positioned position to form pile holes; (3) inserting grouting pipes into the bottoms of the pile holes and injecting slurry by adopting a hole bottom slurry return method until pure slurry emerges from hole openingsof the pile holes, and then stopping grouting; and (4) installing steel pipes at the positions of the pile holes. The construction method has the advantages of short curing time and excellent mechanical properties.
本发明涉及建筑工程技术领域，具体涉及一种利用注浆钢管桩加固复杂地层的施工方法，所述方法包括如下步骤：(1)夯实场地，保证场地平整，进行测量定位；(2)在定位的位置采用钻孔机钻孔，形成桩孔；(3)采用孔底返浆法，将注浆管插至桩孔孔底并注入浆料，直至纯净的浆料从桩孔孔口冒出，终止注浆；(4)在桩孔位置安装钢管。本发明具有固化时间短、力学性能优异的优点。
