Horizontal tank body type experimental apparatus for concealed pipe filter material and experimental method thereof

Abstract

The invention provides a horizontal tank body type experimental apparatus for a concealed pipe filter material and an experimental method thereof and relates to the technical field of concealed pipe drainage. The apparatus comprises a tank body, a concealed pipe, a water tank and a measuring cylinder, wherein the tank body is provided with a first opening hole and a second opening hole which are oppositely formed along the length direction of the tank body; a water inlet is also formed above the second opening hole of the tank body; a filter material is arranged in the concealed pipe; the concealed pipe is provided with a head end and a tail end; the head end and the tail end are respectively arranged at the first opening hole and the second opening hole; the water tank is provided with awater outlet nozzle and a water inlet nozzle; the water inlet nozzle is communicated with a water supply system; the water outlet nozzle is communicated with the water inlet of the rank body by a hose; the measuring cylinder is arranged below the tail end and is used for calculating out displacement within a certain time and a filtering effect by recording time, the displacement and silt discharging amount. The apparatus can simulate actual working conditions of concealed pipe drainage at multidimensional water pressure and experimental data are reliable. Drained water and silt can be completely collected and reliable metering is realized; the filter material and experiment soil are conveniently replaced in a labor-saving manner, and the operability is high.

Description

technical field [0001] The invention relates to the technical field of underground pipe drainage, in particular to an experimental instrument and an experimental method for a horizontal box underground pipe filter material. Background technique [0002] Underground pipe drainage is widely used in groundwater level control and saline-alkali land improvement projects due to land saving and low operating costs. In addition to consuming a large amount of pipe materials, the underground pipe drainage project also consumes a large amount of filter material. The filter material function of the underground pipe drainage is to prevent the sediment in the water flowing into the dark pipe from entering the dark pipe, but to allow the water to flow into the dark pipe relatively smoothly. The principle is to separate the dark pipe from the soil through the filter material, and before the water flows into the dark pipe, it must undergo sufficient precipitation in the filter material, and...

AI Technical Summary

Problems solved by technology

Which filter material has good function and stable performance, and is there any other better filter material? Because the hidden pipe is buried underground in practical application, the drainage effect and filtering function of the filter material cannot be observed
