Fabricated PC wallboard grouting backflow prevention construction technology
The invention discloses a fabricated PC wallboard grouting backflow prevention construction technology. The fabricated PC wallboard grouting backflow prevention construction technology comprises the steps that the installation elevation of a prefabricated PC wallboard is measured, a cushion block is used for leveling to a designed installation elevation, a grouting cavity is divided into single bins, a grouting hole and a grout overflow hole are preset in each single bin, the prefabricated PC wallboard is hoisted, adjusted and fixed, and then base grout joint plugging is conducted; a grouting material is mixed according to a set proportion in accordance with the proportioning condition of the grouting material; the grout overflow hole is plugged after grouting and overflowing until all the sleeves in the single bin are filled with the grouting material, a backflow prevention pipe is inserted into the last grout overflow hole of the single bin, grouting is stopped after grout flows out of the backflow prevention pipe, the grouting hole is plugged, the backflow prevention pipe is pulled out and the last grout overflow hole is plugged when the grouting material in the backflow prevention pipe flows back to fill the grout overflow hole. A test block is retained. According to the fabricated PC wallboard grouting backflow prevention construction technology, the quality problems of splitting deformation and the like caused by incomplete grouting in grouting construction are avoided through the backflow prevention pipe, installation is easy and convenient, construction is convenient and fast, and the project progress can be promoted.
本发明公开了一种装配式PC墙板灌浆防回流施工工艺，包括：预制PC墙板测定安装标高，利用垫块找平至设计安装标高，将灌浆腔分成单仓，每个单仓内预设灌浆孔和溢浆孔，吊装预制PC墙板并进行调整固定，再进行座浆堵缝；以符合灌浆料配料条件，按照设定配比拌制灌浆料；注浆，溢流后封堵溢浆孔，直至单仓内所有套筒中灌满灌浆料，再将一防回流管插入单仓的最后一个溢浆孔，当防回流管流出浆液后停止注浆，并封堵灌浆孔，待防回流管内的灌浆料回流满溢浆孔，拔下防回流管、封堵最后一个溢浆孔，并留置试块。本发明通过防回流管避免了灌浆施工中出现的灌浆不饱满导致的劈裂变形等质量问题，安装简便，施工便捷，有利于推动工程进度。
