Embodiment Construction
[0028] The present invention will be further described below in conjunction with accompanying drawing by non-limiting embodiment:
[0029]As shown in the drawings, a fiber bundle drainage pipe seepage measurement device includes a seepage measurement pipe 1 , a water inlet valve 5 , a water control valve 2 , and a fiber bundle drainage pipe 9 . The seepage measuring pipe 1 is a round pipe with a sealed bottom arranged vertically. The bottom end of the seepage measuring pipe 1 is connected with a bottom plate 4 , and a scale 6 is arranged on the outer wall of the seepage measuring pipe 1 . In this embodiment, the permeameter tube 1 is made of a transparent acrylic glass tube, which can realize the purpose of the visual test. The bottom plate 4 is made of a rectangular acrylic glass plate with a thickness of 1 cm. 4 It can increase the bottom area and ensure the stability of the seepage tube. The scale 6 is a soft ruler with an accuracy of 1 cm, which is pasted vertically on th...

The invention discloses a fiber bundle drain pipe seepage measurement device and a test method. The fiber bundle drain pipe seepage measurement device is characterized in that the device comprises a seepage measurement pipe, a water inlet valve, water control valves and fiber bundle drain pipes, wherein the seepage measurement pipe is a vertically arranged round pipe with a sealed bottom; the bottom end of the seepage measurement pipe is connected with a bottom plate; a graduated scale is arranged on the outer wall of the seepage measurement pipe; a plurality of outwards-extending pipe heads communicated with the interior of the seepage measurement pipe are connected to the pipe wall of the seepage measurement pipe at the same height, wherein a pipe joint is connected to each outwards-extending pipe head; the water inlet valve is connected to the lower portion of the seepage measurement pipe; the water control valves are connected to the positions, at different heights, of the upper portion of the seepage measurement pipe; and one ends of the fiber bundle drain pipes are connected with the pipe joints on the outwards-extending pipe heads. According to the invention, the seepage characteristics of fiber bundle drain pipes with different influence factors and different parameters can be measured under a constant water head or a variable water head. The test efficiency can be improved, and the test result error can be effectively reduced.
Description
technical field [0001] The invention relates to a seepage measurement device for a fiber bundle drainage pipe, which is a test device for measuring the seepage characteristics of a fiber bundle drainage pipe. The present invention also relates to a test method for measuring the seepage characteristics of the fiber bundle drainage pipe by using the above-mentioned fiber bundle drainage pipe seepage measurement device. Background technique [0002] In the analysis of slope stability, hydrological conditions are the main cause of slope deformation and instability. On the one hand, the water inside the slope causes changes in the seepage field, which increases the static water and dynamic water pressure inside the slope, and reduces the shear strength of the soil, while the dynamic water inside the slope generates seepage force, It may also take away the fine particles in the loose or weak structural surface, thus causing slope instability. Some expansive soil slopes are affec...
