Building slant rectification and settlement promotion device and construction method
The invention relates to a building slant rectification and settlement promotion device and a construction method. The building slant rectification and settlement promotion device comprises a buildingfoundation and an anchor cable. A drill hole is drilled in the building foundation. The drill hole penetrates through a sand and gravel layer and a bed rock layer located in a foundation at the bottom of the building foundation in sequence. One end of the anchor cable is inserted into the drill hole and fixed through cement slurry, and the other end of the anchor cable is located outside the building foundation and is tensioned and locked through a work anchor. The building slant rectification and settlement promotion device has the beneficial effects that there is no need to excavate a vertical shaft in the building foundation and the foundation, and thus, damage and interference to the foundation are minimum; during construction, there is no need to conduct operation in a narrow space,the safety risk is low, and operation is easy; the drill hole can be an anchor cable hole or a water flushing deviation rectifying hole; during slant rectification, the anchor cable can achieve the pressurization effect, and can also achieve the repeated slant prevention and reinforcement effects after completion of slant rectification; and the building slant rectification and settlement promotiondevice has multiple purposes and is short in construction period and capable of saving the cost by about 30%.
本发明涉及一种建筑物纠倾促沉装置及施工方法，包括建筑物基础、锚索，建筑物基础上钻有钻孔，且钻孔依次穿过位于建筑物基础底部的地基内的砂卵石层及基岩层；锚索的一端插入在钻孔内，并用水泥浆固定，另一端位于建筑物基础外，并用工作锚张拉锁定；本发明的有益效果为：1、不用在建筑物基础上及地基中开挖竖井，因此对基础损伤最小、对地基干扰最少；施工不用在狭小的空间操作，安全风险低，操作简单；2、钻孔既可用锚索孔，亦可用用冲水纠偏孔，锚索在纠倾过程中，既能起到加压的作用，在纠倾完成之后，又可起到防复倾加固的作用，一物多用，工期较短，节省费用约30％。
