Engineering geology layered water pumping test equipment

Abstract

The invention discloses engineering geology stratified water pumping test equipment, which comprises a main tank body and a relay tank body, the tank wall of the main tank body is provided with a hollow water flow hole, the upper end and the lower end of the main tank body are connected with a first bidirectional piston and a second bidirectional piston through piston cavities, and a first rubberring and a second rubber ring are arranged outside the first bidirectional piston and the second bidirectional piston; the other ends of the first bidirectional piston and the second bidirectional piston are connected with the first pressing mechanism and the second pressing mechanism; the second pressing mechanism is connected with a supporting seat of a bottom connecting rubber seat through a bottom connecting rod; the first pressing mechanism is connected with the relay tank body through a middle connecting rod; a first water pump is arranged in the main tank, a second water pump is arranged in the relay tank, a first conduit connected with a water outlet of the first water pump extends out of the main tank and is connected with a second conduit with the upper end extending into the relay tank through a hose, a water outlet of the second water pump is connected with a third conduit, and a water outlet of the third conduit extends out of the relay tank and is connected with a hose ofthe water tank. By means of the technical scheme, the purpose of measuring the permeability coefficient of the soil body in a layered mode is achieved.

Description

technical field [0001] The invention relates to the technical field of hydrogeological prospecting, in particular to a layered pumping test equipment for engineering geology. Background technique [0002] In engineering construction, groundwater has a huge impact on engineering buildings and engineering construction, such as the construction of dams and embankments in the water conservancy industry, the construction of gates and pumping stations, the construction of diversion tunnels, the excavation of building foundation pits, and the tunnels in the road and railway industries. Construction, in the construction of underground chambers in the mining industry, underground mining and other projects, it is necessary to accurately provide the hydrogeological parameters of each layer of rock and soil. [0003] The existing test devices are mainly simple mechanical welded parts, the operation is complicated and cumbersome, it is very time-consuming and labor-intensive, and the err...

AI Technical Summary

Problems solved by technology

[0003] The existing test devices are mainly simple mechanical welded parts, the operation is complicated and cumbersome, it is very time-consuming and labor-intensive, and the error of the test results obtained is also large; the wall of the drilled hole often collapses in the test, and the success rate of the test is not high; it cannot effectively avoid water , it is difficult to accurately achieve the purpose of stratified water pumping; for the deep test section, the water cannot be pumped out, and the test cannot be carried out
