Detailed Description

The existing tunnel protection door is opened to all opening towards the tunnel cave indoor, but, when carrying out tunnel emergency rescue evacuation, the door body is opened inwards and is unfavorable for the evacuation of the indoor crowd in tunnel cave, simultaneously, when overcast and rainy weather, because the erosion of rainwater makes the protection door rust easily, and when the installation to the protection door, because exhaust improper, lead to the unable effective circulation of inside air easily, reduced the environmental quality of cave, be unfavorable for staff's work.

As shown in fig. 1-6, the device comprises a left base 101 and a right base 102, wherein the left base 101 and the right base 102 are respectively located outside the tunnel 100, the upper ends of the right base 102 and the right base 102 are both provided with arc-shaped doors 300 for protection, the arc-shaped doors 300 on the two sides are connected to the upper ends of the left base 101 and the right base 102 in a half-sector arc-shaped manner, so that the arc-shaped doors 300 can be replaced in the later period, each arc-shaped door 300 comprises a damp-proof board 301, a steel plate 302 and a waterproof board 303, the damp-proof board 301 and the waterproof board 303 are in clamping fit with the steel plate 302 through a plurality of T-shaped blocks 304 on one side, so that the steel plate 302 is wrapped in the middle by the damp-proof board 301 and the waterproof board 303, so as to protect the invasion of external rainwater through the waterproof board 303, and meanwhile, the damp-proof board 301 is used for preventing the internal water vapor from penetrating into the steel plate 302 to corrode the steel plate 302.

Specifically, consider opening left base 101 and right base 102 in-process, because arc door 300 weight is great, difficult removal, consequently, all be equipped with a plurality of pulleys 202 bottom left base 101 and right base 102, then lay track 200 bottom left base 101 and right base 102, the logical groove 201 of cooperation pulley 202 is seted up at track 200 middle part, when pulling left base 101 and right base 102, pulley 202 slides in logical groove 201, thereby reduce the resistance of removal.

Secondly, be located steel sheet 302 symmetry both sides and all seted up T type groove 305, T type groove 305 and the cooperation of the 304 joints of T type piece, and dampproofing board 301 and waterproof board 303 bottom all are equipped with fixture block 306, fixture block 306 and the draw-in groove 501 joint cooperation that left base 101 and right base 102 upper end were seted up, its aim at: through dampproofing board 301, waterproof board 303 and the cooperation of steel sheet 302 joint, long-term the back of using, dampproofing board 301 and waterproof board 303 take place to damage, and the later stage of being convenient for is changed, simultaneously, through the cooperation of the fixture block 306 bottom joint that sets up, the assembly and disassembly of being convenient for.

Preferably, in order to prevent the direct collision between the left base 101 and the right base 102 when the left base 101 and the right base 102 are closed, therefore, a sliding groove 400 is formed in one side of the left base 101, a spring 401 and a limit block 403 are arranged inside the sliding groove 400, and the diameter of the limit hole 103 formed in one section of the right base 102 is the same as that of the limit hole 103, when the left base 101 contacts with the right base 102, the limit block 403 is embedded into the limit hole 103, so that the sliding ring 402 and the limit block 403 compress the spring 401, and the direct collision between the left base 101 and the right base 102 is slowed down under the elastic action of the spring 401.

In addition, in order to facilitate when constructor is under construction in tunnel 100, keep inside circulation of air, so, all be equipped with the inside exhaust hole 500 of a plurality of intercommunication tunnels 100 bottom left base 101 and right base 102, exhaust hole 500 all is certain inclination, not only can make inside and outside circulation of air, can also prevent that outside rainwater from permeating inside tunnel 100.

In conclusion, the working principle of the scheme is as follows: firstly, pass through T type piece 304 joint with dampproof board 301 and waterproof board 303 on the T type groove 305 on the steel sheet 302, thereby form arc door 300, with this prevent that rainwater from corroding steel sheet 302, when closing arc door 300, move to the inboard through left base 101 and the right base 102 that promote both sides, make both sides arc door 300 laminate, at this moment, the pulley 202 of left base 101 and right base 102 bottom slides in logical groove 201, when left base 101 and right base 102 contact, stopper 403 imbeds in spacing hole 103, make sliding ring 402 and stopper 403 compress spring 401, thereby slow down the direct impact of left base 101 and right base 102 under the elastic action of spring 401, when constructor works in tunnel 100 inside, through the exhaust hole 500 of seting up, make inside and outside air circulation, guarantee constructor safety.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only the preferred embodiments of the present invention, and is not intended to limit the present invention, and that there may be various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall within the scope of the present invention as claimed.
