Description

Technical Field

[0001] This utility model relates to the field of structures for safe tunnel construction, and in particular to a structure for ensuring safe construction inside a tunnel. Background Technology

[0002] The construction process of tunnels is very long and difficult, and various situations often arise during this process. The two main problems are tunnel collapse and fire. There are no solutions for these situations in the current technology, which makes it easy for safety accidents to occur once a serious situation occurs during tunnel construction. In order to solve this problem, it is necessary to add some safety protection structures to the existing tunnels during construction. Utility Model Content

[0003] The purpose of this utility model is to provide a safety protection structure for tunnel construction, and to solve the problem that personnel casualties are easily caused when problems occur during existing tunnel construction.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A tunnel safety construction protection structure includes a pre-support foundation cleaning mechanism, a ventilation mechanism, a fire extinguishing mechanism, and an escape mechanism. The pre-support foundation cleaning mechanism is a handheld blower, which is installed inside the tunnel and connected to a power source located on one side of the tunnel wall via a power cable. The ventilation mechanism is suspended and fixed to the top of the tunnel. The fire extinguishing mechanism includes a powder fire extinguisher located on one side of the tunnel and a smoke detector fire extinguisher located on the top of the tunnel. The escape mechanism includes an escape trolley and a refuge trough. The escape trolley is installed on an escape track, which is set along the tunnel opening direction. The escape trolley is connected to a traction motor located at the tunnel entrance. The refuge trough is located on one side of the tunnel.

[0005] This plan first establishes a foundation cleaning mechanism before initial support, using a handheld blower to thoroughly clean the foundation, making the initial support more stable and ensuring construction safety. Then, powder fire extinguishers and smoke detectors are installed. If the fire is small, powder fire extinguishers can be used to extinguish it; if the fire is too large, smoke detectors can be used to extinguish the fire inside the tunnel. If the fire is too large, an escape cart can be used to escape the tunnel, which is faster and safer. Finally, there is a shelter design to provide protection for construction workers in the event of a tunnel collapse.

[0006] As a further preferred embodiment of this utility model, the ventilation mechanism is a ventilation fan, which is mounted on the top of the tunnel via a lifting bracket.

[0007] This allows for easy adjustment of the fan height, making construction easier.

[0008] As a further preferred embodiment of this utility model, the smoke-detecting fire extinguisher includes a smoke detection sensor, a sprinkler head, and a flip-type sand extinguishing mechanism. The flip-type sand extinguishing mechanism includes a left "L"-shaped support plate and a right "L"-shaped support plate. The tops of the left and right "L"-shaped support plates are rotatably connected to the left and right sides of the tunnel ceiling, respectively. The outer surfaces of the left and right "L"-shaped support plates are connected to a hydraulic opening and closing mechanism. Both ends of the hydraulic opening and closing mechanism are hinged structures, and the control switch of the hydraulic opening and closing mechanism is located outside the tunnel.

[0009] In addition to sprinkler fire suppression, a flipping sand extinguishing mechanism can be used after personnel have evacuated from the tunnel for the fastest fire suppression. After the left and right L-shaped support plates flip, the sand they carry falls onto the fire and quickly extinguishes it, thus reducing losses.

[0010] As a further preferred embodiment of this utility model, the entrance of the escape trolley is provided with a flexible heat-insulating and fireproof cover, one end of which is rotatably connected to the entrance of the escape trolley.

[0011] Insulated and fireproof covers can provide heat insulation and fire protection.

[0012] As a further preferred embodiment of this utility model, the avoidance groove is provided with an aluminum alloy triangular support mechanism.

[0013] It provides strong support and can effectively protect people inside in the event of a severe collapse.

[0014] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: 1. In this plan, a foundation cleaning mechanism is first set up before the initial support. A handheld blower can clean the foundation, making the initial support more stable and ensuring construction safety. Then, powder fire extinguishers and smoke detectors are set up. If the fire is small, the powder fire extinguisher can be used to extinguish it. If the fire is too big, the smoke detector can be used to extinguish the fire in the tunnel. If the fire is too big, the escape cart can be used to escape from the tunnel, which is faster and safer. Then, the design of the refuge tunnel can provide shelter for construction personnel in the event of tunnel collapse.

[0015] 2. It makes it easier to adjust the height of the fan, which facilitates construction.

[0016] 3. In addition to sprinkler fire suppression, to extinguish the fire as quickly as possible, a flipping sand extinguishing mechanism can be used after personnel have evacuated from the tunnel. After the left and right L-shaped support plates flip, the sand they carry falls onto the fire and quickly extinguishes it, thus reducing losses.

[0017] 4. The heat-insulating and fireproof cover can play a role in heat insulation and fire prevention.

[0018] 5. Provides strong support and can effectively protect people inside in the event of a severe collapse. Attached Figure Description
