Pressurizing grouting jacking method for top of underpinning column
The invention discloses an underpinning column top pressurizing grouting jacking method which comprises the steps that a sealed grouting space is formed through a fixing steel plate, angle steel, a sealing rubber mat and a sealing plate, conditions are provided for pressure grouting, a support grouting material is selected as a grouting material, and the material is high in strength, rapid in strength increasing, free of shrinkage and easy to pour; grouting materials are poured into the grouting space through the pre-buried grouting pipe, the exhaust pipe is arranged at the top of the grouting space, pressurized grouting is formed in the grouting space along with grouting and gas exhausting, when the strength of the grouting materials reaches the design strength, the jacking work with an existing structure is completed, underpinning has system conversion conditions, each column top can be independently poured, and the construction efficiency is improved. And the method has the advantages of good overall jacking effect, stable system conversion process and no initial sudden change condition, and the method is simple to operate, easy to master, high in process controllability and worthy of popularization.
本发明公开了一种托换柱柱顶增压注浆顶紧方法，包括通过固定钢板、角钢、密封胶垫、密封板形成密封的灌浆空间，为压力灌浆提供条件，灌浆材料选用支座灌浆料，该种材料强度高、强度增长快、无收缩、易于灌注，灌浆料通过预埋的注浆管灌入灌浆空间，灌浆空间顶部设排气管，随着浆液的灌入和气体的排出，在灌浆空间内形成增压灌注，当灌浆料强度达到设计强度后完成与既有结构的顶紧工作，托换具备体系转换条件，而且每个柱顶可单独灌注，也可分组或同时灌注，整体顶紧效果好，体系转换过程平稳，无初期突变情况，且该方法操作简单，易于掌握，过程可控性强，值得推广。
