Description
Technical field
Soil test device is the utility model is related to, especially a kind of experiment dress for being used to determine water-permeable brick infiltration coefficient
Put, extend to the measure of other sample infiltration coefficients.
Background technology
When carrying out permeability test indoors, for model engineering actual conditions, it is necessary to which saturation of first soaking water-permeable brick, connects
And the water-permeable brick of saturation is put into experimental rig again, while also to ensure that the side of water-permeable brick and the full contact of water proof material are close
Envelope, then opens water supply installation and starts to test again.Several big problems be present in traditional permeability apparatus：1), due to the side of water-permeable brick
Obstructed using the poor material of the sealings such as rubber, the air-tightness of device is difficult to reach experimental standard so that experiment gained
Data have larger error with actual conditions；2), because water-permeable brick infiltration coefficient is larger, water can pass through hole and be lost in a part, make
Part hole be full of bubble, water-permeable brick can not be completely secured after experiment starts and be in saturation state for original device, exist compared with
Big error；3), plant bulk is fixed, and can not determine various sizes of sample.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of experiment dress for being used to determine water-permeable brick infiltration coefficient
Put, when can effectively solve the problem that measure water-permeable brick infiltration coefficient, the problems such as existing sealing is poor, and water-permeable brick does not reach saturation, protect
The accuracy of confirmatory test.
In order to solve the above technical problems, technical scheme is used by the utility model：
It is a kind of to be used to determine the experimental rig of water-permeable brick infiltration coefficient, including chassis, overflow launder, overflow are installed on chassis
Groove by butterfly valve control water go out and only；The overflow groove edge is provided with fixing groove, and tank is removably placed on excessive by fixing groove
Chute upper end；Permeable bottom plate in the tank is provided with the inner ring being made up of porous barrier, and water-permeable brick is placed in inner ring and is pushed up
End is provided with the annular groove lid consistent with permeable bottom plate solid area, and water proof material is placed in the interval between inner ring and tank.
Overfall is provided with above the overflow launder.Overfall is used for the draining of Rectangular Water Trough and outside graduated cylinder collects row
Water, it is easy to experiment measurement to obtain authentic data.
The permeable bottom plate, which is located in the region in inner ring, is provided with permeable hole, places in the region of water proof material to be solid
Plate.Permeable area plays a part of permeable and support water-permeable brick, and solid imperforate section can prevent water overflow.
The chassis both sides are provided with handle.Thus facilitate and carry.
The water proof material is bentonite.Bentonite meets water volume expansion and is covered in the four of permeable fragment of brick through porous barrier
Play a part of in week strengthening air-tightness, while can be overflow with waterproof side.
A kind of experimental rig for being used to determine water-permeable brick infiltration coefficient of the utility model, has following technique effect：
1), by setting inner ring with holes in tank, bentonite is set, profit in the gap between tank and inner ring with holes
The surrounding that permeable fragment of brick is covered in after becoming hygral expansion with bentonite plays a part of strengthening air-tightness, ensures water from water-permeable brick upper end
Enter, under bring out, both excluded the influence of side air, accelerated saturation, while model engineering actual conditions, make research have it is actual should
With value.
2), by setting overflow launder below tank, going out and entering for water is controlled by butterfly valve on overflow launder, before experiment,
Make the overflow launder not overflow of device bottom, so that sample just can be at directly carrying out after water suction state reaches saturation inside device
Experiment, without independent immersion saturation, reduce experimental arrangement.
3), overflow launder and tank are the separable structures mutually fastened by fixing groove, therefore need to only change tank, or right
Change tank internal structure and carry out size adjustment replacing, so that it may determine the permeability of various sizes of sample, improve device
Versatility.
