17 diameter；
Sealing material is filled between the sealing steel ring 8 and the section of jurisdiction of tunnel portal 17.
It is closely sturdy in main door plate 1 and tunnel duct piece in this kind of technical solution, since steel loop is smaller than section of jurisdiction diameter, this
Sample will form gap between the two, can use the gluey sealing material filling such as glass cement, section of jurisdiction inner ring and master are played after to be solidified
The sealing function of door-plate 1, to form secondary seal.
In another technical solution, a kind of portal steel construction sealing device of shutter opening and closing formula further includes solid
Determine frame 13, be fixed on the ground outside tunnel portal 17, the fixed frame 13 is fixed with the more cross along tunnel longitudinal direction
Strut 14, one end far from the fixed frame 13 are welded on the main door plate 1 and the main door plate 1 are against the tunnel
Hole 17.
In this kind of technical solution, fixed frame 13 is fixed on the ground outside tunnel portal 17, and is supported with singletree 14
One end of the singletree 14 of firmly main door plate 1, main door plate 1 and fixed frame 13 is welded, even if pressure is larger in Tunnel, can not also be pushed away
Dynamic main door plate 1, ensure that the reliability of the sealing to tunnel portal 17.
In another technical solution, the singletree 14 is retractable structure, and the singletree 14 is solid including one end
The sleeve being scheduled on the fixed frame 13 and the screw rod being threaded in inside the sleeve other end.
In this kind of technical solution, after by the welding on the ground of fixed frame 13, the length for adjusting singletree 14 makes
It, which tightly withstands, resists main door plate 1, and then one end that singletree 14 resists main door plate 1 is welded on main door plate 1.The sleeve
For tubular and inside has internal screw thread, and screw rod is connected to inside the sleeve other end by its external screw thread.
It is not only in the description and the implementation although the embodiments of the present invention have been disclosed as above
Listed utilization, it can be applied to various fields suitable for the present invention completely, for those skilled in the art,
