Wherein: the top of described door-plate is provided with the first through hole, and bottom is provided with the second through hole, described first through hole is provided with multi-functional tube, and described second through hole is provided with gutter.
Wherein: described multi-functional tube and gutter are equipped with valve.
Wherein: there is multiple reinforcing rib the periphery of described junction plate, and the side of described reinforcing rib is soldered to junction plate, and opposite side is soldered to waterproof steel plate.
Wherein: described door body is formed by multiple rectangle framework of welding successively up and down.
Known by said structure, Metro Connection Passage of the present utility model is freezed excavation protective door and is had following effect:
1, structure is simple, easy to operate;
2, when frost wall generation gross distortion, unstability or the harm such as permeable are uncontrollable in digging process, can take to close protective door, invariably descend muddy water to pour in tunnel, cause surface large area thaw collapse and tunnel bury harm;
3, can again recover to freeze, effectively can play to reduce in digging process and endanger the loss brought, reduce construction risk.
Detailed content of the present utility model obtains by explanation described later and institute's accompanying drawing.

Detailed description of the invention
See Fig. 1 to Fig. 5, show Metro Connection Passage of the present utility model and freeze to excavate protective door.
Described Metro Connection Passage is freezed excavation protective door and is comprised door-plate 10 and doorframe 20, and the side of described door-plate 10 is articulated in doorframe 20 so that open, and described doorframe 20 is fixed on tunnel duct piece 30 to realize the use that door-plate 10 is connected with tunnel duct piece 30.
Wherein, see Fig. 1-3, described door-plate 10 comprises rectangular door body 11 and from the outward extending flange 12 of door body surrounding, door body 11 is provided with the handle 13 of convenient operation, and top is provided with the first through hole 14, bottom is provided with the second through hole 15, and described first through hole 14 is provided with multi-functional tube 16 so that pressure wind, slip casting etc., described second through hole 15 is provided with gutter 17, and described multi-functional tube 16 and gutter 17 are equipped with valve.
