Problems solved by technology

For example, the Yesanguan Tunnel on the Yiwan Railway crossed a strong karst area. Due to continuous rainfall, a large-scale water and mud inrush geological disaster occurred shortly after the blasting of the DK124+602 tunnel face of the I Line, resulting in 10 deaths; the Yalong River Hydropower Station A large karst water inrush occurred in the deep-buried exploration pilot tunnel, which washed away the construction facilities and abandoned a construction tunnel; the horizontal guidance construction of the Maluqing Tunnel on the Yiwan Line Railway overlying the solution cavity water body fracturing the arch surrounding rock, resulting in a large water inrush Disaster, the maximum water inrush is as high as 30×10 4 m 3 / h, resulting in 11 deaths

Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] figure 1 Among them, a water inflow acquisition device used for fluid-solid coupling model tests, including a water collection device 1, an adjustment bracket 2 for adjusting its inclination angle is provided under the water collection device 1, and the water collection device 1 is connected to each other through two water diversion devices. The metering device 5 is connected to the pool 7 through the drain pipe 6, and the other channel is directly connected to the pool 7.

[0030] The water collecting device 1 is a stainless steel groove with an arcuate cross-section, and the water collecting device 1 closely fits the tunnel entrance of the fluid-solid coupling model test to ensure accurate collection of water gushing in the tunnel. The two-way water diversion devices 3 and 4 are respectively provided with rubber hoses of control valves. The metering device 5...

Abstract

The invention relates to a water inflow collecting device for a fluid-solid coupling model test and a using method. The water inflow collecting device comprises a water collecting device, an adjusting support for adjusting the inclination angle of the water collecting device is arranged below the water collecting device, the water collecting device is connected with a metering device through one of two paths of water guiding devices, the metering device is connected with a pool through a drain pipe, and the other path of water guiding device is directly connected with the pool. The water inflow collecting device is simple to operate and flexible and convenient to assemble, records data visually and accurately, is used for predicting water inflow, is applied to practical engineering and has guide significance for actual engineering.

Description

technical field [0001] The invention relates to a device for collecting water inflow in a fluid-solid coupling model test, and belongs to the technical field of underground engineering. Background technique [0002] With the vigorous development of underground engineering construction in our country, large-scale geological disasters such as water inrush and mud gushing are constantly encountered in the construction of tunnels, hydropower stations, cross-basin water diversion, and deep minerals in karst areas. Among the catastrophic tunnel accidents at home and abroad, water inrush accidents rank in the forefront in both the number of deaths and the number of occurrences, and the personal casualties and economic losses to the tunnel engineering industry are extremely heavy. For example, the Yesanguan Tunnel on the Yiwan Railway crossed a strong karst area. Due to continuous rainfall, a large-scale water and mud inrush geological disaster occurred shortly after the blasting of...
