Embodiment Construction
[0051] The present invention will be described below in conjunction with specific embodiments.
[0052] Such as Figure 1 to Figure 4 Shown, a kind of reinforcement method of new type prefabricated masonry arch body, it comprises the following steps, specifically:
[0053] a. Prefabricated concrete arch block 111, the concrete arch block 111 is formed by pouring concrete, the longitudinal section of the concrete arch block 111 is in the shape of an isosceles trapezoid and the width value of the upper end of the concrete arch block 111 is larger than the width value of the lower end;
[0054] b. Arrange the prefabricated concrete arch blocks 111 neatly along a straight line according to the required length, and there is a gap between two adjacent concrete arch blocks 111 to form a linear array of arch blocks 11; for placing in the lifting position For concrete arch blocks 111, metal threaded casings 12 are pre-embedded inside, and the upper ends of metal threaded casings 12 ar...
