Precast fabricated concrete member dense sleeve parallel grouting system and method
The invention provides a precast fabricated concrete member dense sleeve parallel grouting system and method. The system comprises multi-row and multi-column steel bars pre-embedded in an existing component, and further comprises multi-row and multi-column sleeves in one-to-one correspondence to the steel bars, adjacent rows of sleeves in all the columns are connected together in series by a horizontal lower connecting pipe and a horizontal upper connecting pipe, the horizontal lower connecting pipe communicates with inner cavities of adjacent sleeves in a through mode into a slurry pouring input channel, the horizontal upper connecting pipe is connected to adjacent sleeves to form a slurry outlet channel, a slurry outlet sleeve is arranged in each column, an upper opening of an inner cavity of each of the remaining sleeves except the slurry outlet sleeve is separated by a slurry separation plate, each column of sleeves are provided with a slurry inlet and a slurry outlet at the outerwall of an assembly component, and slurry enters the first row of sleeves from the slurry inlet and fills all rows of sleeves of the column through the slurry pouring input channel and flows to the slurry outlet channel from the slurry outlet sleeve to flow out of the slurry outlet. According to the system, transferring flow distance of grouting can be reduced, and a grouting hole formed in the surface of a concrete member is further reduced.
本发明提供了一种预制装配式混凝土构件密集套筒并联灌浆系统及方法，该系统包括预埋于现有构件的多排多列钢筋，还包括与钢筋一一对应地的多排多列套筒，每一列中相邻排的套筒由水平下连接管和水平上连接管串接在一起，水平下连接管与相邻套筒的内腔贯通成为浆料灌注输入通道，水平上连接管与相邻套筒连接起来成为出浆通道，每一列中设有一个出浆套筒，除出浆套筒外的其余套筒的内腔上部开口由一隔浆板隔开，每一列套筒在装配构件外壁开设有一个入浆口和一个出浆口，浆料从入浆口进入首排套筒经浆料灌注输入通道灌满该列各排套筒并从出浆套筒流向出浆通道从出浆口流出。本发明可以减少灌浆的传输流动距离，还减少了混凝土构件表面开设的灌浆孔洞。
