Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0031] Such as figure 1 As shown, a prefabricated mid-slab structure of a subway station includes several criss-cross support beams 1 and prefabricated slabs 2. The criss-cross support beams 1 enclose several laying areas, and each laying area is provided with prefabricated slab groups. The prefabricated panel group is composed of one or more than two prefabricated panels 2 connected end to end.

[0032] Such as figure 1 , 2 , 4, the prefabricated slab 2 is a concrete slab, and its size length × width × thickness is 3400mm × 2800mm × 300mm. Two adjacent prefabricated slabs 2 in the prefabricated slab group are tensioned and connected to each other through the connecting piece 8. One or both ends of the prefabricated slabs 2 are provided with wedge-shaped grooves, and the wedge-shaped grooves at the ends of two adjacent prefabricated slabs 2 are co...

Abstract

The subway station assembly type middle plate structure comprises a plurality of criss-cross supporting beams and prefabricated plates, a plurality of laying areas are defined by the criss-cross supporting beams, a prefabricated plate set is arranged in each laying area, each prefabricated plate set is composed of one or more prefabricated plates connected end to end, supports are arranged on the inner sides of the supporting beams, and the prefabricated plates are arranged on the inner sides of the supporting beams. An acrylate spraying coating is arranged on the support, and the prefabricated slab group is pressed on the acrylate spraying coating; gaps are formed between the side faces of the periphery of the prefabricated slab set and the side faces of the supporting beams, third acrylate spraying layers are arranged in the gaps, every two adjacent prefabricated slabs in the prefabricated slab set are connected through a connecting piece in a tensioning mode, and fourth acrylate spraying layers are arranged on the opposite end faces of the adjacent prefabricated slabs. An acrylate spraying method is adopted to adapt to waterproof sealing of various joints of the assembly type structure, and the problem of water leakage of the joints of the assembly type middle plate structure is solved.

Description

technical field [0001] The invention relates to the field of underground engineering waterproofing, in particular to an assembled mid-slab structure of a subway station and a construction method thereof. Background technique [0002] In recent years, there are few research results on waterproofing of related underground projects in foreign countries, which is related to the environmental conditions and infrastructure construction in various countries; the recent domestic research results are relatively rich, covering tunnels, subways, integrated pipe corridors and various underground spaces. The enclosure system, such as the floor, side walls, roof and other parts, adopts a fully-wrapped or fully-covered waterproof method, including the roof of the prefabricated subway station and the prefabricated pipe gallery still adopts a fully outsourced waterproof method, only for the segments of the shield technology. Seam connections are sealed for waterproofing. From the perspectiv...
