Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] attached figure 1 It is the front view of the model test bench, with figure 2 And attached image 3 to attach figure 1 A-A and B-B sectional views. The pressure-bearing outer wall (1) is processed by high-strength thick seamless steel pipe, in a cylindrical shape, and the wall thickness is greater than 20mm. attached Figure 4 It is the front view of the inner shelter, and the inner shelter (2) is welded by high-strength thick steel plates, and uniformly distributed water inlet holes (9) are processed on the opposite side of the shelter. The tunnel opening (3) is made of steel pipe and welded with the pressure-bearing outer wall (1) and the inner shelter (2). The outer wall of the tunnel opening is processed with standard threads, which can be connected to high-pressure valves.

Abstract

The invention belongs to the field of testing devices, and relates to a water outburst and mud outburst testing device for a high pressure-bearing tunnel. The a water outburst and mud outburst testing device comprises a model test bench and a pressure stabilizing device, wherein the model test bench is divided into three parts, namely an internal square cabin, an external pressure-bearing outer wall and a tunnel opening; the internal square cabin is arranged in the pressure-bearing outer wall; the tunnel opening is welded in the internal square cabin and the pressure-bearing outer wall; and the pressure stabilizing device is used for providing stable water pressure for the test bench and is composed of a high-pressure nitrogen tank and a gas-liquid compound constant-pressure water tank. The water outburst and mud outburst testing device is capable of simulating water outburst and mud outburst processes under high pressure, and achieving a good and lasting pressure stabilizing effect.

Description

Technical field [0001] The invention belongs to the field of test devices, in particular to a simulated test device for water and mud inrush in high-pressure-bearing tunnels. Background technique [0002] With the rapid development of economic construction, the transportation network, water conservancy and hydropower and other infrastructure are constantly improving, and more and more deep-buried tunnel projects will appear. Deep-buried tunnel projects are threatened by high pressure water and often encounter water inrush. Mud disasters have had a major impact on engineering construction and people's property safety. In order to explore the internal mechanism and catastrophe law of water and mud inrush in tunnels under the action of highly confined water, it is necessary to be equipped with corresponding test equipment. The relevant test equipment in the past can be divided into two categories: one is the water and mud inrush test device for simulating the tunnel excavation...
