Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a composite sealing and odor-proof structure. Background Technology

[0002] With rapid urbanization and increasingly scarce land resources, finding new landfills has become extremely difficult and can easily trigger social conflicts. Waste-to-energy incineration plants, with their relatively small footprint and high processing efficiency, are a practical solution to the problem of municipal solid waste disposal in large cities. High-temperature incineration significantly reduces the volume of waste, greatly alleviating the pressure of "garbage siege," extending the lifespan of landfills, and conserving valuable land resources. The slag produced after incineration can be processed to separate scrap iron, scrap copper, and other metals for recycling, further realizing resource recycling. Power generation and heating provide direct economic income. At the same time, the construction, operation, and maintenance of incineration plants require a large workforce, creating stable employment opportunities. While waste-to-energy incineration plants play a crucial role in treating municipal solid waste and achieving resource reuse, odor leakage is indeed a prominent and concerning issue in the industry, with expansion joints in the main structure being one of the main points of odor diffusion. In conventional floor expansion joint design, it is usually composed of cover plate, base, waterstop and matching bolt connection parts, etc. It reduces the internal stress of the main structure when the building expands and contracts due to temperature changes or uneven settlement. It generally cannot achieve the sealing effect. Utility Model Content

[0003] The main purpose of this invention is to propose a composite sealing and odor-proof structure, which aims to improve the odor diffusion problem in existing expansion joints.

[0004] To achieve the above objectives, the present invention proposes a composite sealing and odor-proof structure for installation at expansion joints with slots in waste-to-energy plants. The composite sealing and odor-proof structure comprises a concrete component, a sealing body, and a first cover plate. The concrete component is cast in the slot in a secondary process. The sealing body is installed within the expansion joint. The first cover plate is installed within the slot and covers the concrete component.

[0005] In one embodiment, the composite sealing and odor-proof structure further includes a second cover plate, which is sealed and installed on the side of the expansion joint away from the groove.

[0006] In one embodiment, the sealing body is provided with at least one of a fire-resistant part, a waterproof part, a sealing part, and a heat-insulating and air-proof part.

[0007] In one embodiment, the fire-resistant part includes a fire-resistant strip, which is disposed on the side of the expansion joint away from the groove.

[0009] In one embodiment, the waterproof section includes at least one set of asphalt putty and / or a waterstop.

[0010] In one embodiment, the waterstop is surrounded by asphalt-impregnated hemp fibers, which are used to seal the gaps around the waterstop.

[0011] In one embodiment, the heat-insulating and air-barrier portion comprises rigid polyurethane foam.

[0012] In one embodiment, it further includes a sealant, which is disposed in the inner cavity of the concrete component and located inside the first cover plate.
