Description

Technical Field

[0001] The utility model relates to the technical field of tunnel drainage, in particular to a tunnel drainage pipe crystallization clogging simulation device. Background Art

[0002] There are many types of tunnel projects, including mountain tunnels, underwater tunnels and urban tunnels, among which mountain tunnels are the most numerous. Among mountain tunnels, many tunnels pass through karst areas. The problem that comes with the development of high-speed roads is the maintenance of completed tunnels. Tunnels passing through karst areas face the problem of blockage in their tunnel drainage systems. Once the drainage system is blocked, it will cause the water pressure behind the lining to increase, which will cause water seepage in the tunnel at the least, and directly affect normal driving at the worst.

[0003] In order to study the mechanism of crystallization blockage in tunnel drainage pipes, a tunnel drainage pipe crystallization blockage simulation device was developed. Utility Model Content

[0045] Example

[0046] like Figure 1 and 2 As shown, this embodiment provides a tunnel drainage pipe crystallization blockage simulation device, including a main container 10, an experimental pipeline 20, a transfer container 30 and a reflux system 40.

[0047] Specifically, the main container 10 is used to store the experimental solution; the experimental pipeline 20 is used to transport the experimental solution; the transfer container 30 is used to receive the experimental solution transported by the experimental pipeline 20; and the reflux system 40 is used to transport the experimental solution in the transfer container 30 to the main container 10.

[0048] Specifically, the transfer container 30 has an energy dissipation device 50, which is used to consume the potential energy of the experimental solution discharged from the experimental pipeline 20. The energy dissipation device 50 is configured to be movable on the transfer container 30 along a direction away from / close to the experimental pipeline 20.

The assembly rack 60 has a clamping and positioning mechanism 61, and the clamping and positioning mechanism 61 is used to fix the experimental pipeline 20. The assembly rack 60 is located between the transfer container 30 and the main container 10.

[0052] Exemplarily, the clamping and positioning mechanism 61 is a pipe clamp.

[0053] In this embodiment, the energy dissipation device 50 includes a retaining frame 51 , a movable component 52 , a guide cover 53 and an impeller 54 .

[0054] Specifically, the movable component 52 is configured to be slidably connected to the retaining frame 51; the deflector 53 is configured to be fixedly connected to the movable component 52; the impeller 54 is configured to be rotatably connected to the deflector 53, and the impeller 54 is used to convert the potential energy of the experimental solution into rotational mechanical energy.
