摘要：装配式剪力墙结构建筑施工过程中，灌浆作业是竖向构件安装的关键工序，竖向构件内的钢筋套筒连接质量是影响结构安全的关键控制点，灌浆不密实或套筒内空腔对建筑结构安全有严重影响。本文通过对装配式剪力墙结构钢筋套筒连接气压式补浆技术的研究，针对传统灌浆方式进行气压式补浆，发现气压式补浆技术极大地提高了套筒内灌浆密实度，并避免出现空腔现象，能及时发现堵孔塞脱落或连通腔破损问题，有效保证钢筋套筒灌浆连接的施工质量。

Abstract: in the construction process of prefabricated shear wall structure, grouting is the key process of vertical component installation. The connection quality of reinforcement sleeve in vertical component is the key control point affecting structural safety. Loose grouting or cavity in sleeve has a serious impact on the safety of building structure. In this paper, through the research on the pneumatic grouting technology of the reinforced sleeve connection of the fabricated shear wall structure, the pneumatic grouting is carried out according to the traditional grouting method. It is found that the pneumatic grouting technology greatly improves the grouting compactness in the sleeve, avoids the cavity phenomenon, and can find the problem of the falling off of the plug or the damage of the connecting cavity in time, Effectively ensure the construction quality of reinforcement sleeve grouting connection.

During the construction of prefabricated shear wall structure, grouting is the key process of vertical component installation, and the connection quality of steel sleeve in vertical component is the key control point that affects the structural safety. Grouting is not dense or the cavity in sleeve has a serious impact on the structural safety of building. In this paper, through the research of pneumatic grouting technology for reinforced sleeve connection of prefabricated shear wall structure, aiming at the traditional grouting method, it is found that pneumatic grouting technology greatly improves the grouting density in the sleeve, and avoids the cavity phenomenon, which can timely find the problem of the plug falling off or the damage of the communication cavity, and effectively ensure the construction quality of reinforced sleeve grouting connection.
