Embodiment Construction
[0041] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.
[0042] refer to figure 1 The method for preventing cracks at the joint between the concrete structure and the backfill wall of the present invention mainly includes three steps: masonry construction of the fill wall, plastering construction of the fill wall, and construction of anti-crack tape on the joint. Each step is described in detail below.
[0043] 1. Masonry construction of infill wall
[0044] 1. Interface processing
[0045] Before masonry, brush the concrete interface of the connection part with cement mortar glue, and the thickness of the cement mortar glue brush is ≤3.0mm.
[0046] The composition and weight ratio of cement mortar glue are:
[0047] 901 construction glue: cement: sand = 1:1.5:1.
[0048] It has been verified that the cement mortar glue of this composition has high bonding strength.
[0049] 2. Pre-plast...
