目前,我国的单排孔小砌块断面形状尚未统一,各地从不同角度出发,提出了自己的砌块断面方案.有些砌块由于断面的设计不尽合理,不能充分发挥材料的潜力,造成浪费.据了解,国内的单排孔小砌块有图1中a～f多种断面.其中a常见于农村,这是因为形成园孔的模芯容易自制,而且脱模时的 At present, the cross-sectional shapes of small blocks of single rows of holes in China are not yet unified. Various localities have proposed their own block section plans from different perspectives. Some blocks have failed to make full use of the potential of the materials due to the unreasonable design of the cross-section and cause waste. It is understood that the domestic single-hole small blocks have various cross-sections from a to f in Fig. 1. Among them, a is common in rural areas. This is because the cores forming the boreholes are easy to be self-made and demoulding
