Novel deviation self-correcting open caisson and deviation correction method thereof
The invention discloses a novel deviation self-correcting open caisson and a deviation correction method thereof and belongs to the technical field of bridge open caisson foundations. The novel deviation self-correcting open caisson comprises an open caisson, a bottoming concrete plate and an open caisson top plate, wherein a plurality of caisson holes arranged in the form of matrix are arranged in the open caisson; every two adjacent caisson holes are spaced from each other through an open caisson wall; the caisson holes in the inner ring of the open caisson are sealed caisson holes; the caisson holes in the outer ring of the open caisson are deviation self-correcting caisson holes; the bottoming concrete plate is sealed at the bottom of the open caisson; the open caisson top cover is positioned at the top of the open caisson; sand filling and water drainage holes are formed in the open caisson top cover; the sand filling and water drainage holes communicate with the deviation self-correcting caisson holes; and the sand filling and water drainage holes are used for filling the deviation self-correcting caisson holes with sand stones or draining water from the deviation self-correcting caisson holes. According to the novel deviation self-correcting open caisson and the deviation correction method thereof, water is pumped out from the deviation self-correcting caisson holes in the inclined direction to reduce the weight according to the inclined direction of the open caisson; the deviation self-correcting caisson holes reverse to the inclined direction are filled with sand stones to increase the weight of the deviation self-correcting caisson holes so as to realize loading in the reverse direction; and therefore, the open caisson generates anti-inclination bending momentto realize deviation correction of the open caisson foundation.
本发明公开了一种新型自纠偏沉井及其纠偏方法，属于桥梁沉井基础技术领域，包括：沉井，沉井内设有多个呈矩阵式排列的井孔，相邻的两孔井孔之间通过沉井井壁隔开，位于沉井内圈的井孔为封闭井孔，位于沉井外圈的井孔为自纠偏井孔；封底混凝土板，其封堵在沉井的井底；沉井顶盖，沉井顶盖位于沉井的顶部，在沉井顶盖上开设有注砂排水孔，注砂排水孔与自纠偏井孔连通，注砂排水孔用于向自纠偏井孔内注砂石或排水。本发明的自纠偏沉井即纠偏方法根据沉井的倾斜方向，在倾斜方向的自纠偏井孔内抽水减重，在与倾斜方向相反的自纠偏井孔内注入砂石增重，实现反方向加载，使沉井产生抗倾斜弯矩，实现沉井基础的纠偏。
