一、机械用途为了检验喷射混凝土的各项物理力学性能,我们研制了761型混凝土切割机(图号:三标I8001)以解决大量试件的制取问题。该机是检定喷射混凝土质量所必需的基本试验设备,它可以制取供作抗压、抗拉、抗折强度试验和测定弹性模量用。制作试件的尺寸分别为10×10×10厘米、10×10×40厘米及10×10×30厘米三种。 First, the use of machinery In order to test the physical and mechanical properties of shotcrete, we developed a 761-type concrete cutting machine (Figure No.: three standard I8001) to solve the problem of a large number of sample preparation. This machine is the basic test equipment necessary to verify the quality of shotcrete. It can be used for compressive, tensile and flexural strength tests and for measuring elastic modulus. The dimensions of the test specimens were 10 x 10 x 10 cm, 10 x 10 x 40 cm, and 10 x 10 x 30 cm.
