Method for constructing water proof structure and constructing underground construction in water proof mode

The invention discloses a method for constructing a water proof structure and constructing underground construction in a water proof mode. The method for constructing the water proof structure includes the steps that positioning steel tubes are laid on the outer periphery of prebuilt underground construction in the direction perpendicular to the extending direction of a vertical shaft after the vertical shaft is excavated for the prebuilt underground construction; micro steel tubes are jacked into the space between adjacent positioning steel tubes on the outer periphery of the prebuilt underground construction in the direction perpendicular to the extending direction of the vertical shaft; the adjacent positioning steel tubes and the micro steel tubes are connected through fore shafts and adjacent micro steel tubes are connected though fore shafts to form a water proof tube curtain encircling the outer periphery of the prebuilt underground construction; grout is injected into the micro steel tubes; water stop blocking plane bodies perpendicular to the positioning steel tubes and away from the vertical shaft at different distances are constructed in the underground space defined by the water proof tube curtain; annular supporting bodies parallel to the water stop blocking plane bodies are formed between adjacent water stop blocking plane bodies along the inner side wall of the water proof tube curtain. The water proof structure constructed through the method has the good water proof effect, and enables the water proof tube curtain to have strong rigidity.
