灌注桩基础是指使用人力推钻大锅锥钻进粘土泥浆护壁成孔或用机械钻进粘土泥浆护壁成孔,清孔后安放导管灌注水下混凝土或井孔内安放钢筋笼灌注水下混凝土成为支撑上部结构的基础就叫灌注桩基础。原阳县地处黄河北岸,地形为南高北低,自然地势由西南向东北方向倾斜,土质属黄河冲积壤土,透水性强,质地松软,地下水位埋深较浅(地面下2~4m),县境内有大中型引黄灌区3处,引黄灌溉渠系跨越较大沟河的建筑物工程多采用灌注桩基础修建。引用灌注桩基础是在60年代开始的,从人力推钻大锅锥成孔修建混凝土灌注桩发展到使用机械成孔修建钢筋混凝土桩,此项目不仅在引黄灌区内广泛使用,并发展到交通公路、房屋建筑的基础处理应用,甚为普遍。
Pouring pile foundation refers to the use of manpower to push large pot taper into the clay mud wall into the hole or mechanical drilling into the clay mud wall into the hole, clear the hole after the placement of catheter infusion of underwater concrete or well hole placed under the cage filled with water Concrete to become the basis for supporting the superstructure called perfusion pile foundation. Yuanyang County is located in the north bank of the Yellow River. The terrain is high in the south and low in the north. The natural terrain slopes from southwest to northeast. The soil belongs to the alluvial loess of the Yellow River. The soil is of high permeability, soft texture and shallow groundwater table (2 ~ 4m below ground) There are 3 large and medium-sized dredging irrigated areas in the county. Construction projects of dredging irrigation canals that span large ditches are mostly constructed with bored pile foundation. The foundation of quoted bored pile began in the 1960s. The development of concrete bored pile from manpower drilling cauldron caulking hole to the construction of reinforced concrete piles using mechanical bored hole was widely used in this project not only in the Yellow River Diversion Irrigation Area but also to Traffic roads, housing construction, basic processing applications, is very common.
