[0033] Example:
[0034] This embodiment provides a TBM construction auxiliary cavern, which is used to solve the technical problem that the auxiliary cavern in the prior art cannot ensure the safety of trapped persons. The TBM construction auxiliary cavern includes a chamber 1 connected to an escape passage, a shell 2, a positioning component and a moving component, wherein:
[0035] The chamber 1 has an entrance and an exit that are arranged opposite to each other. The entrance is opened on the inner wall of the tunnel. A door panel is hinged at the entrance. The door panel is used to open or close the entrance. The exit of the chamber 1 is connected to the escape passage.
[0036] The shell 2 is arranged in the chamber 1, and has an opening on the shell 2, and is connected to the inlet. Optionally, the shell 2 is a structural member made of high-strength steel. Specifically, the shell 2 is surrounded by a top plate, a bottom plate and four side plates. The top plate, the bottom plate and the four side plates can be connected together by welding or hot melting. Of course, they can also be integrally formed. Optionally, the cross-sectional area of the top plate gradually increases in the direction from the top end of the top plate to the bottom end. In this way, when a stone falls on the top plate, the stone slides along the smooth top surface to the ground, reducing the probability of stones accumulating on the top of the shell 2.
[0037] The positioning assembly is installed on the shell 2, and the positioning assembly is used to fix the shell 2. In this way, the setting of the positioning assembly facilitates the fixing of the shell 2 to avoid shaking of the shell 2 in the cavity in the event of an accident, thereby avoiding collision between the shell 2 and the chamber 1.
[0038] The moving component is installed at the bottom end of the shell 2, and the moving component is used to drive the shell 2 to move. Through the setting of the moving component, when the shell 2 needs to be moved into the chamber 1, the moving component can be first installed on the shell 2, and then the shell 2 is driven to move into the chamber 1 by the moving component. It is convenient and quick. Alternatively, when an accident occurs, the trapped construction workers can drive the shell 2 to move in the escape passage through the moving component, thereby taking all the trapped construction workers out of the tunnel at the same time.
[0039] Through the above structure, when using the TBM construction auxiliary cavern provided by the utility model, first a chamber 1 connected to the escape passage is opened in the tunnel, and then the shell 2 is moved into the chamber 1 by the moving component, and then the shell 2 is fixed in the chamber 1 by opening the positioning component to prevent the shell 2 from moving in the chamber 1. When an accident occurs in the tunnel, the construction personnel enter the shell 2 through the opening on the shell 2, and then the positioning component is closed. Finally, the shell 2 is driven by the moving component to move the shell 2 in the escape passage until all the trapped construction personnel are sent out of the tunnel. In this way, when an accident occurs again during the movement of the construction personnel in the escape passage, the construction personnel are covered in the shell 2 by the shell 2 to reduce the probability of safety accidents occurring to the construction personnel. Therefore, through the arrangement of the shell and the moving component, the TBM construction auxiliary cavern provided by the utility model can not only avoid danger, but also move in the escape passage, so that the construction personnel can reduce the probability of being injured when moving in the escape passage.
[0040] An optional implementation of the present embodiment is as follows: the positioning assembly includes two telescopic parts, one ends of the two telescopic parts are respectively fixedly mounted on opposite sides of the shell 2, the other ends of the two telescopic parts abut against the inner wall of the chamber 1, and the two telescopic parts are coaxially arranged. In this way, through the arrangement of the two telescopic parts, when the shell 2 needs to be fixed in the chamber 1, it is only necessary to extend the two telescopic parts until the other ends of the telescopic parts abut against the inner wall of the chamber 1, so that the shell 2 is fixed in the chamber 1; when the shell 2 needs to be moved, it is only necessary to shorten the two telescopic parts until the other ends of the telescopic parts are separated from the inner wall of the chamber 1, and the two coaxially arranged telescopic parts make the force on the shell 2 more uniform, thereby making the shell 2 fixed more firmly.
[0041] Optionally, the telescopic part is a telescopic cylinder 3, which uses liquid pressure to achieve the telescopic function, has a high torque output capacity, can withstand a large load, and has a long service life, reducing maintenance costs and failure rate during use. The telescopic cylinder 3 has a simple structure, a small size, is easy to install, and has a fast response speed.
[0042] An optional implementation of this embodiment is as follows: it also includes two connecting members 5, and the two connecting members 5 are respectively fixedly installed on the other ends of the two telescopic members. Through the setting of the connecting members 5, the contact area with the inner wall of the chamber 1 is increased, thereby making the shell 2 more firmly fixed.
[0043] Optionally, the end of the connecting member 5 away from the telescopic member is arc-shaped, that is, the contact surface between the connecting member 5 and the inner wall of the chamber 1 is arc-shaped. In this way, through the setting of the arc-shaped surface of the connecting member 5, the connecting member 5 and the inner wall of the chamber 1 are more closely fitted, and the contact area between the connecting member 5 and the inner wall of the chamber 1 is further increased, thereby further enabling the shell 2 to be more firmly fixed in the chamber 1.
[0044] An optional implementation of the present embodiment is as follows: placement grooves are provided on opposite sides of the shell 2, specifically, the placement grooves are adapted to the connecting piece 5, and installation grooves are provided at the bottoms of the two placement grooves. One end of the two telescopic pieces are respectively installed at the bottoms of the two installation grooves, and the placement grooves are used to place the connecting piece 5. In this way, the installation grooves are provided to facilitate the installation of the telescopic pieces, and the placement grooves are provided so that the connecting piece 5 can be completely placed in the placement grooves, thereby preventing the shell 2 from scratching against the side wall of the chamber 1 during movement, thereby causing damage to the connecting piece 5.
[0045] An optional implementation of this embodiment is as follows: the moving component includes four rollers 4, all of which are rotatably installed at the bottom of the shell 2, and the four rollers 4 are located at the four vertices of the same rectangle. Specifically, it also includes a control component for controlling the rolling and turning of the rollers 4. In this way, through the setting of the moving component, it is easier for construction personnel in the shell 2 to control the movement and turning of the shell 2.
[0046] An optional implementation of this embodiment is as follows: it also includes an electric hammer 6, which is placed in the shell 2, and the electric hammer 6 is used to break stones. In this way, through the setting of the electric hammer 6, when the escape passage is blocked by stones, the electric hammer 6 can be used to break them, thereby preventing the stones from blocking the escape passage and preventing the trapped construction workers from escaping.
[0047] An optional implementation of this embodiment is as follows: it also includes a filter layer 7, and a vent is opened on the side wall of the shell 2. The filter layer 7 is installed at the vent 21. The filter layer 7 is used to filter dust in the air. In this way, through the setting of the vent 21, sufficient oxygen in the shell 2 is guaranteed, thereby avoiding oxygen deficiency for trapped construction workers. The setting of the filter layer 7 filters dust in the air and reduces the probability of dust entering the shell 2.
[0048] An optional implementation of this embodiment is as follows: it also includes a placement rack 8 installed in the shell 2, and the placement rack 8 is used to place rescue items. Through the setting of the placement rack 8, rescue items such as food, water, and oxygen cylinders can be placed in advance.
[0049] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
