Embodiment 1

[0039] Embodiment 1, the present invention is a tunnel water and mud inrush model test device and method, including a support base 1, the support base 1 is placed on the ground to provide a fixed support foundation for subsequent structures, the support base 1 The upper end is fixedly connected with a feeding bin 2, and the upper end of the feeding bin 2 is fixedly connected with a feeding frame 3. Through the feeding frame 3, soil can be injected into the feeding bin 2. The feeding bin 2 There is a built-in support mold 4, the support mold 4 and the feeding bin 2 are gap-fitted, and the front end of the support mold 4 is detachably connected with a tunnel model 5. When the support mold 4 is placed in the feeding When inside the silo 2, inject soil into the gap portion of the supporting mould 4 and the feeding bin 2 through the feeding frame 3, and cover the supporting mould 4 with soil;

[0040] The inner wall of the feeding bin 2 is fixedly connected with a ram air bag 6, an...

Embodiment 2

[0043] Embodiment 2, on the basis of Embodiment 1, in the process of spraying water on the soil, water will remain in the soil, causing the water body to flow sluggishly, and the problem of not being able to shoot to the outside smoothly, so this embodiment Provide a structure for diverting the water in the soil to ensure the smooth flow of the water body in the soil. The lower end of the support base 1 is provided with a lower permeable hole 12 which is matched with the said permeable hole. In order to ensure that the water body in the said feeding bin 2 will not be scattered everywhere, the said upper permeable hole 11 is close to the said tunnel model. 5. A water retaining strip is fixedly connected on one side, and the water retaining strip prevents the water flow from flowing around. The lower end of the support base 1 is fixedly connected with a liquid return silo 13, and the liquid return silo 13 is pre-stored with water. The liquid return bin 13 is provided with a wate...

Embodiment 3

[0044] Embodiment 3, on the basis of Embodiment 1, due to the difference in temperature environment, the phenomenon of water and mud inrush in the tunnel will be affected. In order to create a different temperature environment, the temperature environment where the tunnel model 5 is located is changed. The embodiment provides a structure for adjusting and controlling the temperature environment. Specifically, the upper end of the support base 1 is fixedly connected with a thermal insulation shield 14 sleeved on the outside of the feeding bin 2. The thermal insulation shield 14 It is a double-layer thermal insulation structure, the described feeding bin 2 is covered by the described thermal insulation protective cover 14, the described feeding bin 2 is protected, and the temperature environment near the described feeding bin 2 is controlled at the same time, Reduce the exchange of the temperature near the feeding bin 2 and the external environment to ensure that the feeding bin ...

Abstract

The invention provides a model test device and method for tunnel water inrush and mud inrush, which solves the problem that the existing tunnel water and mud inrush process is only analyzed by ANSYS finite element, and the entity research test of the tunnel water and mud inrush process cannot be carried out through model tests. It includes the support seat, the upper end of the support seat is fixedly connected with the feeding bin, the upper end of the feeding bin is fixedly connected with the feeding frame, the feeding bin has a built-in support mold, the support mold and the feeding bin are clearance fit, and the front end is detachably connected with a tunnel model, The inner wall of the feeding bin is fixedly connected with a stamping airbag, which is connected with the air supply pump fixedly connected to the feeding bin, and a number of soft water spray pipes are fixedly connected to the side of the charging airbag close to the supporting mold. The water supply pipe at the upper end of the feeding frame is connected, and the water supply pipe is connected with the external water supply device; the present invention has an exquisite structure and strong practicability.

Description

technical field [0001] The invention relates to the technical field of tunnel construction simulation, in particular to a tunnel water and mud inrush model test device and method. Background technique [0002] In the process of construction and use of tunnels, there are serious geological disaster risks such as water and mud inrush, especially for deep-buried tunnels, water and mud inrush disasters often have the characteristics of suddenness, large flow, and high water pressure. The tunnel will be submerged, the construction will be interrupted, and serious casualties and economic losses will be caused, and some projects will even be forced to stop construction or reroute. Scholars at home and abroad have done a lot of theoretical and model test research on the mechanism of water inrush and mud inrush disaster and the variation characteristics of displacement field, stress field and seepage field in the process of disaster evolution. There are few studies on the impact of ...
