我国地域辽阔,建筑工程地基与基础施工中遇到的地质情况也较为复杂,在沿海地区及江河湖泊地区进行建筑施工时,常常遇到软粘土、淤泥质土等软弱土层,福建地区较常用的地基处理方法主要有冲孔灌注桩,预制管桩,水泥搅拌桩,高压旋喷桩、地基换填、强夯法、超载预压等地基处理施工工艺,这些地基处理方法均存在各自的局限性,不能满足“节能、节材、节水、节地”的绿色环保施工要求。因此,本文对现浇混凝土大薄壁管桩施工技术在建筑工程地基处理中的应用进行探讨。
Geological conditions encountered in the vast territory of our country and in foundation construction and foundation construction of construction projects are also quite complicated. In the construction of coastal areas, rivers, lakes and lakes, we often encounter soft soil layers such as soft clay and muddy soil, and are commonly used in Fujian Province The foundation treatment methods are mainly punching and pouring pile, precast pipe pile, cement mixing pile, high pressure rotary jetting pile, foundation replacement, dynamic compaction method, overloading and preloading and other foundation treatment construction techniques. These foundation treatment methods have their own limitations Can not meet the “green energy saving, material saving, water saving, land” green construction requirements. Therefore, this article discusses the application of cast-in-situ concrete thin-walled pipe pile construction technology in construction engineering foundation treatment.
