Embodiment Construction
[0038] The following are specific embodiments of the present invention and combined with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.
[0039] like Figure 1-3 and Image 6 As shown, a construction method for anti-leakage inner and outer walls includes: S1, respectively setting a first template 1 and a second template 2 at the pre-built inner and outer walls; wherein, the first template 1 and the second template 2 are arranged at intervals, and the first template 1 and the second template 2 enclose a cavity 10 for forming inner and outer walls; in this solution, the first template 1 and the second template 2 are arranged in parallel and spaced apart, and the first template 1 and the second formwork 2 are made of wood formwork or plywood. In order to ensure the strength of the first formwork 1 and the second formwork 2, square wood or square steel pipes are also pr...

The invention relates to the technical field of construction engineering, and discloses a construction method for anti-leakage interior and exterior walls, which includes: respectively setting a first formwork and a second formwork at the prefabricated interior and exterior walls; the two form a cavity; A fastening device is provided between the two; wherein, the fastening device includes a pull bolt, the pull bolt is passed between the two, and a pre-embedded pipe is sleeved on the pull bolt, and the pre-embedded pipe is in the cavity The pre-embedded pipe fittings include an outer wall arranged on a conical surface, and the outer diameter of the pre-embedded pipe fittings gradually increases from the side close to the first formwork to the side close to the second formwork; pouring concrete into the cavity to form an inner and outer wall, and waiting for the concrete to solidify When it reaches the preset state, remove the fastening device and pull out the embedded pipe fittings from the inner and outer walls; fill the two ends and the middle of the pipe holes left by pulling out the embedded pipe fittings with expansive waterproof mortar and foamed polyurethane respectively. The invention has the advantages that the construction method has good waterproof and anti-leakage effects; the pre-embedded pipe fittings are convenient to use and simple in structure.
Description
technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction method for anti-seepage inner and outer walls. Background technique [0002] The inner and outer walls can usually be formed by template, and the templates are connected and fixed by clamps and tension bolts. After the inner and outer walls are formed, the tension bolt will leave a through hole on the inner and outer walls. After removing the tension bolt , the through hole needs to be filled to prevent water leakage, but since the through hole is filled later, not poured together with the inner and outer walls, the rainproof and waterproof effects are difficult to achieve the expected effect. [0003] Since the outdoor side of the inner and outer walls is exposed to sunlight and rain, after long-term use, cracks, water leakage and water seepage are prone to occur at the through hole, that is, the water from the outdoor side penetrates into the ind...
