Underground water pipe well water pumping simulation device for centrifugal model test and test method thereof

Abstract

The invention belongs to the field of underground space development, and relates to an underground water pipe well water pumping simulation device for a centrifugal model test and a test method thereof. According to the technical scheme, the water pumping simulation device is arranged on a hanging bucket of a centrifugal machine; the underground water pipe well water pumping simulation device comprises a main model box used for being filled with simulation soil and simulation underground water, an auxiliary model box used for being filled with simulation underground water, a water storage tank and a water pumping system. The auxiliary model box is located on the side edge of the main model box and communicates with the main model box through a communicating pipe at the bottom. The water storage tank is mounted above the auxiliary model box, and a one-way exhaust valve is mounted at the top; an air inlet pipe and a water outlet pipe are mounted in holes in the bottom of the water storage tank and extend downwards into the auxiliary model box; the water pumping system is controlled by a variable-frequency water pump and comprises a tube well and a water guide pipe; the tube well extends into the main model box; and the other end of the water guide pipe extends into the water storage tank. The simulation of underground water pipe well water pumping in a centrifugal model test is achieved.

Description

technical field [0001] The invention belongs to the field of underground space development, and in particular relates to an underground water pipe well pumping simulation device and a test method for centrifugal model test. Background technique [0002] With the increasing shortage of urban land resources, underground space development has become an important means to solve problems such as urban land use, population, traffic, and environment, and to optimize urban spatial structure. With the development of shallow underground space becoming more and more saturated at this stage, the development of deep and large underground space has also become an inevitable trend of underground space resource utilization, which has brought a large number of deep foundation pit projects. Most of the hotspots for underground space development and construction are located in coastal areas along the river, where deep aquifers, abundant water volume, high head pressure and strong permeability ...

Problems solved by technology

The geotechnical centrifuge model test is carried out in an overweight, closed, and narrow space. Under this condition, it is a complicated process to realize the foundation pit pumping process, boundary water head simulation, and data acquisition. At present, there are no mature test equipment and related technical achievements. Simulation of Tube Well Pumping Process in Centrifugal Model Test
