Construction method for reinforcing indoor hollowing floor through grouting after being reversely jacked by common scaffold
The invention relates to a construction method for reinforcing an indoor hollowing floor through grouting after being reversely jacked by a common scaffold, and belongs to the technical field of indoor ground hollowing repairing. The construction method comprises the following operation steps that firstly, a normal area and a hollowing area are determined on a floor surface layer through slight striking of a rubber hammer; secondly, an overflow hole and a grouting hole are punched according to the range of the hollowing area, and the overflow hole and the grouting hole extend to the lower end of the floor surface layer from the upper end of the floor surface layer to communicates with a lower floor base plate; thirdly, reverse jacking supports distributed in a concentric square shape are arranged on the periphery of the normal area, and a plurality of transverse or longitudinal reverse jacking supports are arranged in the hollowing area; and fourthly, slurry is prepared, the slurry is injected from an outer ring to an inner ring of the hollowing area through a grouting pipe, when grouting is saturated, the slurry overflows from the overflow hole, and the grouting process at the grouting hole is stopped. The construction method has the advantages of convenient construction, time and labor saving and good stability. It is guaranteed that a cavity is full in grouting, and the repairing quality of building ground hollowing is guaranteed.
本发明涉及一种室内空鼓地坪采用普通脚手架反顶后注浆加固的施工方法，所属室内地面空鼓修补技术领域，包括如下操作步骤：第一步：在地坪面层上采用橡胶锤轻击确定正常区域与空鼓区域。第二步：根据空鼓区域范围大小打溢出孔和注浆孔，溢出孔和注浆孔从地坪面层上端延伸至地坪面层下端与下层楼基板连通。第三步：接着在正常区域外围设置呈‘回’字形状分布的反顶支架，空鼓区域内设置横向或纵向的若干反顶支架。第四步：配置浆料，通过注浆管将浆料从空鼓区域外圈至内圈注入，当注浆饱和时，浆液就从溢出孔溢出，停止注浆孔处的注浆过程。具有施工便捷、省时省力和稳定性好的优点。确保空腔注浆饱满，保证了建筑地面空鼓的修补质量。
