Abstract

A double-leaf protective closure obstruction door for a subway one-hole and two-lane section comprises door leafs, a door frame, jack devices, latches and hinges, wherein the door frame consists of an upper door frame, two lateral door frames and a lower door frame; the door leafs are structured in a double-leaf form and are provided with a center joint sealing device therebetween; the lower door frame is equipped with a movable doorsill slot thereon and is connected with a detachable movable doorsill; the movable doorsill includes a movable doorsill beam, a bearing plug fixedly connected to the movable doorsill beam and matched with the movable doorsill slot, and a railway sealing piece fixedly connected to the movable doorsill beam and matched with a railway sealing box; and the movable doorsill beam is additionally connected with a bottom sealing device. The obstruction door disclosed by the invention is suitable for the section partition of urban subway traffic civil defense engineering with two lanes in a tunnel, the use safety for wartime of the one-hole and two-lane section or a two-lane tunnel section with smaller interval can be ensured, and the great convenience can be brought to the transformation from peacetime to wartime.

Description

technical field [0001] The invention relates to a protective airtight partition door installed in a subway project. Background technique [0002] Underground urban rail transit is an important part of modern urban public transportation. Underground urban rail transit projects are usually underground traffic arteries. In wartime, they are not only evacuation arteries for urban civil air defense, but also can be used as personnel shelters. It can ensure the safety of personnel and equipment under the secondary disasters of the city during and after the attack, and can improve the comprehensive protection capability of the entire city. [0003] The underground urban rail transit project after fortification is a large-scale civil air defense project composed of many stations connected by section tunnels. Protective airtight partition doors that can withstand shock wave loads in both directions are installed in the section tunnels between them. In this way, the stations are conn...
