A model test stabilized pressure water adding system and its operation method

Abstract

The invention discloses a model test pressure stabilization water feeding system and an operation method of the model test pressure stabilization water feeding system. The model test pressure stabilization water feeding system comprises an air compressor, wherein the air compressor is connected with a pressure stabilization water storage device through a gas pipe; the pressure stabilization water storage device is connected with a flow monitor and a pressure transmitter through a water pipe in sequence; the pressure transmitter is connected with a point source water feeding device; the pressure stabilization water storage device is connected with a booster pump through a water feeding pipe; water outlets are formed in the bottom and outer side of the point source water feeding device. According to the model test pressure stabilization water feeding system, by filling a similar material inside the point source water feeding device and pre-embedding a model test bed to simulate water storage and diversion structure of geotechnical engineering, stable dynamic water environment can be provided for a grouting model test, important indexes such as pressure and flow in a water delivery process can be monitored, acquired and displayed in real time, and the water delivery pressure and flow can be adjusted in real time according to feedback information to meet model test requirements. The current situation that the current grouting model tests are performed under no water or still water condition, which does not accord with actual conditions of a grouting engineering is changed.

Description

technical field [0001] The invention relates to a model test stabilizing water adding system and an operation method thereof. Background technique [0002] At present, geological disasters such as water inrush and mud inrush often occur during the construction of underground projects such as tunnels and mines in my country, which may delay the construction period in the slightest and cause a large number of casualties and economic losses in severe cases. At present, the method of grouting reinforcement is mostly used to solve such problems, and the effect is obvious, but water inrush and mud inrush accidents still occur frequently. The reason is that the current grouting construction relies too much on experience and lacks scientific and reasonable theoretical guidance. , The development of grouting theory lags far behind engineering practice. [0003] The model test method can simulate complex geological structures more comprehensively and truly, discover some new mechanic...

Problems solved by technology

[0004] At present, some grouting model tests have been carried out at home and abroad, and some results have been obtained. However, most of the tests are carried out under anhydrous or still water conditions, which is inconsistent with the current situation that most grouting projects are carried out in dynamic water environments, which also leads to The research results have great limitations, which limit the development of grouting theory
