[0041] Example

[0042] A transparent soil test device for simulating groundwater seepage in a dewatering confined aquifer in a foundation pit, the structure of which is as follows: Figure 1-2 As shown, the test device includes a model box 1, a water tank 2, a water pipe 3, a threaded steel rod 4, a cover plate 5, an intermediate cover plate 7, a wooden board 6 for simulating a ground wall, a pumping well pipe 12, a wooden board 13, and a glass tube 14. Mig paper 16 and other components. The model box 1 is rectangular, and its structure is as follows image 3 As shown, the left and right side walls and the front side wall are made of tempered glass, and the back side wall is made of steel plate. Pressure measuring holes 8 with a diameter of 10 mm and an interval of 100 mm are designed on the back side wall steel plate. Simultaneously seal the pressure measuring hole 8 with a solid plastic short rod of considerable diameter, just pull out the solid plastic short rod if the h...

Abstract

The invention relates to a transparent soil test device use for simulating seepage of foundation pit dewatering confined aquifer underground water.The transparent soil test device use for simulating seepage of foundation pit dewatering confined aquifer underground water comprises a model casing, a cover plate arranged in the model casing, a plank simulating a concrete diaphragm wall, water tank elements connected on both sides of the model casing to control confined groundwater level, and a piezometer tube system used for measuring the water pressure of strata of different depths and arranged on the backface of the model casing.Compared with the existing technology, the seepage paths of water flows around a waterproof curtain can be directly observed, and seepage path rules, seepage velocity and other relevant parameters can be accurately analyzed through photos shot by a high-speed camera; and seepage laws of distances between different concrete diaphragm walls and the plane and the section of a filter tube can be obtained by changing the insertion ratio of the concrete diaphragm walls and the length of a pumping filtering pipe.

Description

technical field [0001] The invention belongs to the technical field of foundation pit dewatering engineering, in particular to a transparent soil test device for simulating groundwater seepage in a foundation pit dewatering confined aquifer. Background technique [0002] With the rapid development of my country's economy, urbanization has been carried out across the country. In order to meet the growing needs of citizens for basic functions such as travel, rail transit transfers, commerce, and parking, especially in dense urban centers where land use is increasingly tight , the development and utilization of underground space has become an irresistible trend. As an important part of underground engineering, foundation pit engineering is constantly expanding in scale, from small shallow foundation pits to ultra-deep and super-large areas. Especially in the most economically developed Yangtze River Delta region, due to the relatively high groundwater level, foundation pit prec...
