The invention discloses a construction method of a waterproof, unloading and smoke mixing prevention integrated indoor exhaust duct structure, which comprises the following steps of: 1, preparing a connecting pipe hoop which is made of a flame-retardant soft PVC (Polyvinyl Chloride) material; secondly, a bell mouth of each connecting pipe hoop is hooped and sleeved on an upper opening of one flue located below the connecting pipe hoop, and a lower opening of one flue located above the connecting pipe hoop is inserted into an inserting opening of each connecting pipe hoop; the fixing steel bars on each connecting pipe hoop are fixedly connected with reserved stressed steel bars at the positions of floor slabs of all floors and a floor structural slab of a first kitchen or toilet, and non-shrinkage anti-seepage concrete is poured in reserved flue openings outside all the flues. By the adoption of the method, the flue is prevented from generating accumulated loads, and it is guaranteed that the lower-layer flue is not pressed and damaged due to weight transfer of the upper-layer flue.

Seepage-preventing and water-stopping structure for water conservancy projects
ActiveCN107938603AImprove construction efficiencyEasy to carryMarine site engineeringHydraulic engineeringSoil surface
The invention provides a seepage-preventing and water-stopping structure for water conservancy projects and belongs to the field of water conservancy projects. The seepage-preventing and water-stopping structure comprises a long-strip-shaped box body; a long-strip-shaped containing cavity is formed in the lower portion of the box body; a water-proof film coil is arranged in the containing cavity,and the containing cavity is provided with a long-strip-shaped opening for communicating with the outside world; long-strip-shaped clamping strips which are detachably connected with the top of the box body are arranged at the top of the box body; and the clamping strips are provided with clamping parts which can clamp the ends of water-proof films. In the water conservancy construction process, the seepage-preventing and water-stopping structure is laid in the soil surface where water and soil erosion is prone to occurring, and through the seepage-preventing and water-stopping effects of thewater-proof films, water and soil are conserved; and the structure is convenient to construct and easy to carry, and can be applied to the water conservancy projects on a large scale, and thus the construction efficiency of the water conservancy projects is improved.
