[0032] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0033] In the description of this application, it should be noted that the terms "inside", "outside", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the application is usually placed when in use, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0034] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] The tunnel communication channel emergency door in this application is mainly used for the construction of tunnel communication channels. By setting a transfer mechanism for the emergency door at the hole in the communication channel, the stability and reliability of the emergency door installation are enhanced, and at the same time, the impact of collapsed materials in the communication channel on the emergency door is buffered, so as to minimize the construction safety risk.

[0036] See also Figure 1 , and combined with Figure 2-Figure 3 The tunnel communication channel emergency door in the utility model mainly includes a door frame 1 and a door panel 2. The emergency door is specifically installed between the excavated communication channel 3 and the formed tunnel. The tunnel is composed of concrete pipe segments, and a steel pipe segment 4 is arranged at the hole of the communication channel 3.

[0037] The purpose of setting the steel pipe segment 4 is mainly to install the emergency door, which is conducive to welding between steel structures and ensures the structural strength. In order to further enhance the stability of the emergency door installation in this application, a reinforcement frame 5 is connected between the steel pipe segment 4 and the door frame 1. By connecting the reinforcement frame 5 to the steel pipe segment 4 and connecting the door frame 1 to the reinforcement frame 5, the reinforcement frame 5 can constitute a transition reinforcement structure between the emergency door and the steel pipe segment 4. Further, the reinforcement frame 5 plays a good buffer role to prevent the direct impact of the geological structure of the collapsed communication channel 3 on the emergency door in the event of an emergency.

[0038] Since the reinforcement frame 5 is protrudingly arranged on the tunnel side, by arranging reinforcement closures on both sides of the reinforcement frame 5, the lateral gap between the reinforcement frame 5 and the pipe segment can be blocked, thereby increasing the contact area between the collapsed geological structure and the emergency door, and relatively reducing the extrusion force applied to the emergency door.

[0039] The side of the door panel 2 is hingedly connected to the door frame 1. Specifically, the emergency door is opened and closed by opening the door panel 2 flatly toward the tunnel side, thereby improving the convenience of emergency operation.

[0040] During the construction of the connecting channel 3, if a dangerous situation occurs, the emergency door needs to be closed in time to prevent water and soil from flowing into the tunnel. Then, if necessary, cement slurry needs to be injected into the connecting channel 3 to stabilize the excavated water and soil surface. Finally, after the geological structure in the connecting channel 3 is stabilized, the emergency door is opened for excavation again.

[0041] In the present application, by providing grouting holes 7 on both the door panel 2 and the reinforcement cover plate 6, cement slurry injection operation can be effectively performed, construction efficiency is improved, and the unstable geological structure in the communication channel 3 is fully covered.

[0042] In one specific embodiment, the reinforcement frame 5 includes two bending reinforcement ribs 51 bent toward the steel pipe segment 4, and the door frame 1 is installed between the two bending reinforcement ribs 51. The bending reinforcement ribs 51 are welded to the surface of the steel pipe segment 4, so that the connection strength between the reinforcement frame and the steel pipe segment 4 is guaranteed under the premise of effective installation of the reinforcement frame.

[0043] Based on the overall frame structure of the reinforcement frame 5 , the top and bottom sides of the bending reinforcement ribs 51 are respectively connected with reinforcement beams 52 , and both ends of the reinforcement beams 52 are respectively connected to the bending reinforcement ribs 51 .

[0044] In order to further enhance the structural strength of the reinforcement frame 5 itself, reinforcement columns 53 are connected between the reinforcement beams 52. The reinforcement columns 53 and the reinforcement beams 52 form a square flat frame structure, which, combined with the bent reinforcement ribs 51 connected to the reinforcement beams 52, constitute the overall structure of the reinforcement frame 5.

[0045] The flat frame structure composed of the reinforced cross beam 52 and the reinforced column 53 constitutes the installation outer frame of the door frame 1. By connecting the door frame 1 to the installation outer frame and connecting the bent reinforcement ribs 51 to the steel pipe segment 4, the transfer effect between the reinforced frame 5 relative to the steel pipe segment 4 and the door frame 1 is effectively achieved.

[0046] From the installation perspective of the door frame 1 , the door frame 1 and the mounting outer frame are connected and installed by fastening bolts, thereby ensuring that the door frame 1 is installed stably and reliably on the reinforcement frame 5 .

[0047] In another specific embodiment, the reinforcement sealing plate 6 includes two pieces. Specifically, each reinforcement sealing plate 6 includes a steel plate with a relatively high thickness. Structurally, the side close to the tunnel is a straight-edge structure for connection with the reinforcement column 53, and the side close to the connecting channel 3 is an arc-edge structure for connection with the curved reinforcement rib 51.

[0048] By installing the reinforcement cover plate 6 at the position between the curved reinforcement rib 51 and the reinforcement column 53, the isolation effect produced by the emergency door can be effectively ensured.

[0049] From the perspective of injecting cement slurry, the grouting holes 7 include side grouting holes 71 located on both sides. The side grouting holes 71 are arranged on both sides of the reinforcement frame 5. The grouting holes 7 on both sides are opened on the reinforcement sealing plate 6, and the side grouting holes 71 on both sides are relatively located on the reinforcement sealing plate 6, so grouting can be performed evenly, making the grouting reinforcement treatment more balanced.

[0050] It should be pointed out that the side grouting hole 71 is opened in the middle part of the reinforcement sealing plate 6 to reduce the impact on the structural strength of the reinforcement sealing plate 6 and ensure basic sealing performance.

[0051] In addition to grouting on the side, the grouting holes 7 in this embodiment also include emergency door grouting holes 72. The emergency door grouting holes 72 are opened on the door panel 2, which can effectively inject cement slurry from the front into the communication channel 3, thereby improving the operational efficiency of injecting cement slurry, and at the same time, can more fully reinforce and stabilize the unstable geological structure in different parts and spaces.

[0052] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.

[0053] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
