Pre-laying waterproof coiled material construction process for welding and adhesive bonding combined construction

[0053] This embodiment provides a welding and gluing combined construction pre-laying waterproof membrane construction process, which is used for a construction site with a concave structure, including the following steps:

[0054] S1. Preparation before construction: clean the base surface to ensure that the base surface is clean, flat and firm without water accumulation, treat the inner corners with cement mortar, and prepare auxiliary materials, construction machines and tools;

[0055] S2. Plane coil laying: pre-lay plane coils, respectively perform long-side lap and short-side lap and seal the lap joints;

[0056] S3. Internal corner position processing: cutting the coiled material at the internal corner and performing pre-laying and lapping treatment;

[0057] S4. Coil paving on the façade: lapping the façade and strengthening the lap seam;

[0058] S5. Coil damage repair: repair the damage existing in the coil.

[0059] Further, step S2 specifically includes the followin

[0089] This embodiment provides a construction process of pre-laying waterproof coiled materials combined with welding and gluing, which is used for construction sites with concave structures. The difference from Example 1 is that the construction site in this embodiment belongs to piles. In the case of the construction step, step S1 also includes the treatment of the pile head, specifically: using the prepared cement-based waterproof coating, first wet the pile head, the pile body and the surrounding area with water, and then apply water on the top surface of the pile head and The side is painted with cement-based waterproof paint, and extended to 200mm of the structural bottom cushion.

[0090] Further, the specific steps of step S2 also include:

[0091] S25, filling and compacting with cement mortar at the junction of the pile head and the coiled material;

[0092] S26. After the cement mortar is dry, apply a 100mm-wide node sealing paste on the root of the pile head and its
