在我国砖混结构楼房抗震加固施工中,长期以来一直采用短拉杆连结。这种方法最大的缺点是拉结不可靠,室内操作工序繁多,工效低,对住户干扰太大。后来,又推广了“压浆锚杆”工艺,基本上解决了上述问题。但在压浆锚杆施工中,尚无一种理想的专用施工机具。普遍采用空气压缩机,只能单独用于充气,且实用价值低,造价高。如 In the construction of aseismic reinforcement of brick-concrete buildings in China, short tie rods have been used for a long time. The biggest disadvantage of this method is that it is not reliable, the indoor operation process is numerous, the work efficiency is low, and the interference to the occupants is too great. Later, it also promoted the “grouting anchor” process, which basically solved the above problems. However, in the construction of grouted bolts, there is no ideal dedicated construction equipment. Commonly used air compressors can only be used for inflation alone, and have low practical value and high cost. Such as
