摘　　要：预制剪力墙全灌浆套筒连通腔工艺与坐浆工艺对比分析:制作12个预制剪力墙,将其等分为2组,在预制剪力墙上埋设套筒,每组试件分别进行预制剪力墙全灌浆套筒连通腔操作和预制剪力墙坐浆套筒连通腔操作,利用振动传感器对腔内混凝土进行振动测试,采集浆料振动能量值,通过对腔内浆料进行超声波检测,采集腔内浆料孔隙率。结果显示:预制剪力墙全灌浆套筒连通腔工艺浆料振动能量值和孔隙率低于坐浆工艺。由此可知:预制剪力墙全灌浆套筒连通腔工艺浆料饱和程度高于坐浆工艺,并且浆料孔隙率低于坐浆工艺,故在实际工程中应优先考虑采用全灌浆套筒连通腔工艺。To compare and analyze the process of connecting cavity with grouting sleeve of precast shear wall.Twelve prefabricated shear walls were made and divided into two groups,and sleeves were buried in the prefabricated shear walls.Each group of specimens underwent cavity connection operation of the full grouting sleeve of the prefabricated shear wall and cavity connection operation of the grouting sleeve of the prefabricated shear wall respectively.Vibration sensors were used to test the vibration of the concrete in the cavity,collect the vibration energy value of the slurry,and through ultrasonic detection of the slurry in the cavity.The slurry porosity in the cavity was collected.Results:The vibrational energy and porosity of the slurry in the full grouting sleeve connecting cavity process are lower than those in the grouting process.Conclusion:The slurry saturation degree and the porosity of the slurry are higher than that of the grouting process,so the slurry slurry connecting cavity process should be given priority in practical engineering.
