One embodiment of the invention provides a method for installing a sliding rail push-pull folding type protective airtight door, which comprises the following steps:

step 1: the method comprises the following steps that a vertical frame is installed, the vertical frame comprises a door frame, a door frame support, a suspension frame and a suspension frame support, and a straight anchor rod and an anchor plate are welded on the outer side faces of the door frame 1 and the suspension frame;

step 2: pouring concrete of the door frame wall, wrapping the straight anchor rods and the anchor plates in the door frame wall by pouring the door frame wall, and reserving a decoration layer, wherein the depth of the decoration layer is 100 mm;

and step 3: dismantling the door frame support and the suspension frame support, and installing a support and a guide rail;

and 4, step 4: the pulley is arranged on the guide rail, the door leaf, the locking mechanism and the suspension device are assembled, the door leaf is lifted, the suspension device is in butt joint with the pulley, the positioning column is inserted into the positioning hole, and the fastening bolt is connected to fasten the pulley and the first connecting seat.

And 5: debugging the door leaf and the door frame, aligning the sealing position of the door leaf and the door frame, and welding a limiting block.

The invention has the following beneficial effects: meets the protection requirements (5 grade for nuclear 5 and 6 grade for nuclear 6) for preventing nuclear explosion and explosion resistance of conventional weapons. And the door leaf meets the requirement of air tightness after being closed. The barrier-free passage (the door leaf is arranged between the hidden doors at ordinary times, and the passage of pedestrians and goods is not influenced) is realized, and the barrier-free passage is fixed between the hidden doors at ordinary times, hidden storage is realized, and the barrier-free passage is quickly installed in place during wartime. Compared with a plugging plate, the equipment is simple and rapid in peacetime and war time conversion and can be completed by single person operation. The problem of stacking of plugging plates is solved. The sealing rubber strip 11 is automatically extruded along with locking and locking of the door leaf, the compression amount of the rubber strip is controllable, and the influence of manual operation is small. The bearing type slide rail has strong bearing capacity and small sliding resistance. The suspension device restrains the redundant degree of freedom of the door leaf, and can effectively prevent the door leaf from shaking. The knife edge is embedded and pressed for sealing, and the sealing performance is good. The door leaf is only pushed manually, so that the door leaf can move towards the direction of the door frame, and the embedded pressing strip is in sealing fit with the sealing strip, so that the door leaf and the door frame between the door leaf are sealed and closed quickly, and the door leaf is sealed and closed quickly in wartime.
