Detailed description of the invention
Below in conjunction with accompanying drawing, technical solution of the present invention is described in detail, but protection scope of the present invention is not limited to embodiment.
As depicted in figs. 1 and 2, under the oblique seepage force effect of the present embodiment, Piping phenomenon analog includes water tank the 1, first water conservancy diversion water pipe 2, drum 3, base 4, expansion link 5, band tubing 12, glass tubing 11, water tank 1 is by the first water conservancy diversion water pipe 2) connect drum 3, drum 3 embeds base 4, simultaneously hinged by an expansion link 5, the pressure-measuring pipe 7 of drum 3 is connected with glass tubing 11 by band tubing 12, dash platform 9 is arranged at drum top, and a jiao of platform has a second water conservancy diversion water pipe 8 for water guide training for sediment.
Outer on water tank take a water delivery water pipe, adjustable tap thus control the discharge of water delivery water pipe, a drain pipe 16 is arranged at the top of water tank, and when water tank 1 middle water level is too high, water will be dredged by drain pipe 16.
Drum 3 is provided with the first hinged-support 13, and base 4 is provided with the second fixed-hinged support 14, and the two ends of expansion link 5 are hinged with first hinged-support the 13, second hinged-support 14 respectively.Drum 3 bottom is domed bottom 6, embedding with base 4 in, be freely rotatable, drum 3 can be regulated to a certain required inclination angle, adjustable telescopic rod 5 makes it support drum 3 and not topple over.
The internal position on the lower side of drum 3 is provided with the first baffle plate 10, the sandstone that can be accepted on top is isolated with lower space, porous, and lower space communicates with the through hole of domed bottom, when constantly there being water to flow out from through hole, the first baffle plate 10 bottom will be a water-filled space.
The sidewall of drum 3 has scale at the through hole end same plane of domed bottom 6 to drum top dash platform 9, it is simple to test is the particular location that record piping occurs.
The sidewall of drum is circumscribed with eight pressure-measuring pipes, wherein seven tops being positioned at described first baffle plate 10 of drum, one lower section being positioned at described first baffle plate 10 of drum 3, pressure-measuring pipe 7 communicates with the inside of drum 3, the part that pressure-measuring pipe 7 is connected with drum is provided with second baffle, can be permeable every sand, prevent the sandstone within drum from entering pressure-measuring pipe and being allowed to block.
Further, each pressure-measuring pipe 7 is all connected with a glass tubing 11 by a band tubing 12, and when being full of water in drum 3, water will be by pressure-measuring pipe 7, in band tubing 12 enters glass tubing 11, can get the head of pressure-measuring pipe 7 position by reading the height of water column in glass tubing 11.
One dash platform 9 is arranged at drum 3 top, slightly higher compared with drum cylinder open, the sandstone gushed out from drum 3 when can accept test and water, is circumscribed with the second water conservancy diversion water pipe 8 to derive sandstone and water on dash platform at dash platform 9 one jiao.
Using method and the operation principle of this utility model device are described as follows:
Step one, void ratio, grating according to the soil body carry out dispensing, the coarse-fine aggregate mixed is loaded in three times in drum 3, first baffle plate 10 upper space is adequately filled up, the sample that vibrates after often completing loading sample once is allowed to closely knit, place elastic tape and smear 704 marine glues, it is to avoid quickly forming seepage channel cause sample to destroy owing to the hole of sidewall is relatively big.
Step 2, being connected with glass tubing 11 with band tubing 12 respectively by eight pressure-measuring pipes of drum 3 sidewall, glass tubing 11 is parallel to each other, and lower end flushes, and is fixed on a certain motionless place, and glass tubing 11 is marked with scale, it is simple to record water-column.
Step 3, open faucet, water filling in water tank 1, draws high water tank 1 simultaneously, the water level controlled in water tank 1 is slightly above the height of sample in drum 3, drum 3 middle water level slowly rises, and top has swelling to go out, and is flowed out by the second water conservancy diversion water pipe 8 of 9 one jiaos of dash platform.
Step 4, rotation drum 3 are until it is horizontal by required angle, and adjustable telescopic rod 5 makes drum 3 be fixed simultaneously.
Step 5, when device is after steady statue, i.e. water level in water tank 1 keeps stable, has a small amount of water to continuously outflow, stand 24 hours, make the air in sample fully discharge, reach saturation in the second water conservancy diversion water pipe 8.
Step 6, lifting water tank 1, adjustable tap makes the water level in water tank 1 keep stable, measure the height of water level of Water in Water Tanks, when the continuous lifting of water level, the seepage force that in drum 3, sample is born constantly becomes big, and water, the sand gushed out from drum 3 are to increase, can measure the sandstone in water conservancy diversion water pipe 8, the discharge of water learns concrete numerical value, meanwhile, the also constantly lifting of the water level in the glass tubing 11 being connected with drum 3 sidewall pressure-measuring pipe 7, comparison scale obtains head value concrete at pressure-measuring pipe 7.
Step 7, change gross head height, i.e. Water in Water Tanks position height, until sample generation failure by piping, off-test.
Should note preventing water leakage when this device re-uses, the preferable material of waterproof effect should preferentially be chosen by each material as far as possible.
This device can change the inclination angle of drum, the height of water tank thus simulate the soil body under by oblique seepage force effect from saturated, to producing seepage channel, arrive generation piping again, until the overall process destroyed, provide a kind of new research method for research Piping phenomenon under oblique seepage force effect.
As above, although the most closely represent and indicate the present invention with reference to specific preferred embodiment, but it shall not be construed as the restriction to the present invention itself.Under the spirit and scope of the present invention premise defined without departing from claims, can various changes can be made in the form and details to it.
