Subway station reverse roof fully-wrapped waterproof structure and construction method

Abstract

The invention discloses a subway station reverse roof fully-wrapped waterproof structure. A reverse roof (5) is arranged on one side of an enclosure structure (1). The subway station reverse roof fully-wrapped waterproof structure is characterized in that the subway station reverse roof fully-wrapped waterproof structure comprises a waterproof roll (3) and a side wall (6), a groove is formed in the portion, on one side of the reverse roof (5), of the enclosure structure (1), the portion over the groove is made of plain concrete (2), and the side wall (6) is arranged on the portion, close to the enclosure structure (1), of the bottom of the reverse roof (5); and a roof protrusion (4) is arranged at the end of the reverse roof (5) and arranged in the groove, the thickness of the roof protrusion (4) is matched with the height of the groove, the waterproof roll (3) is clamped to the joint of the roof protrusion (4) and the plain concrete (2) and the joint of the enclosure structure (1) andthe side wall (6), and the two ends of the waterproof roll (3) stretch out a length. The invention further discloses a construction method of the subway station reverse roof fully-wrapped waterproofstructure. Therefore, fully-wrapped waterproofness of the reverse roof is achieved.

Description

technical field [0001] The invention belongs to the technical field of upside-down roofs, and more specifically relates to an all-inclusive waterproof structure and construction method for upside-down roofs of subway stations. Background technique [0002] The technical principle of reverse construction is to construct the underground structure of high-rise buildings layer by layer from top to bottom, that is, to construct continuous walls or close-packed piles along the basement of the building, as the enclosure structure of the outer wall of the basement or the foundation pit, and at the same time build In the relevant position inside, the piles are supported in the middle of the construction floor to form an upside-down vertical load-bearing system, and then a layer of earthwork is dug from top to bottom, and a layer of basement beam-slab structure is poured together with soil molds. When a certain strength is reached, it can be As the inner horizontal support of the encl...

Problems solved by technology

Although the waterproof layer is covered on the outer periphery of the pressure wall beam and the inner wall of the main enclosure structure, on the one hand, this scheme emphasizes the main body of the station. The externally protruding pressure wall beams are set on the enclosure structure, the structure is complex, the construction is difficult, and the structural stability of the pressure wall beams protruding outside the wall is difficult to control
