Background technology
The highway distress problem of Saline Region relates generally to that salt swollenly, molten falls into, corrosion etc., the reason of disease all has relation with water, salinity will move by moisture, find the characteristics of motion and the lifting height of salinity to hinder the harm of salinity to embankment, the method for exploring the capillary water height that is applicable to embankment fill material is the task of top priority.
At present, done detailed regulation for T0128-1993 capillary water lifting height test in existing " highway earthwork test rule " (the JTG E40-2007) of capillary water height.In this specification, the internal diameter of plexi-glass tubular is less, only has 4.0 ~ 4.5cm, and in so little diameter, moulding sample is difficult to ensure its compactness, if coarse particle sample just cannot moulding also cannot complete test; And on tube wall, need open a duck eye every 10cm, tube wall punch will certainly cause pipe in and pipe outside air Contact Effect capillary water rise too high or too low; At pipe spring control supply tank at the end, thereby its complex structure and spring easily deform and affect the accuracy of test findings.
Summary of the invention
The purpose of this utility model is to provide a kind of device that embankment fill material capillary water rises of simulating, and sample moulding is simple and approaching with on-the-spot reality.
For addressing the above problem, the utility model provides a kind of device that embankment fill material capillary water rises of simulating, and comprises a columnar examination cylinder, and an examination barrel, apart from 1.5cm place at the bottom of cylinder, encircles the circular hole of all drill diameter 5mm every 2cm; The high 100-200cm of examination cylinder, internal diameter 18-27cm, wall thickness 1-1.5cm; Examination cylinder is placed in base, and base is made up of the cylinder of base plate and base plate top, and base plate is connected by methenyl choloride solvent with cylinder; The high 10cm of cylinder of base, diameter 25-40cm, top is higher than the circular hole of examination cylinder; The cylinder of base is provided with water inlet and water delivering orifice, and water inlet accesses tap bottle by conduit, and tap bottle top sets out gas port; Flow controller is installed on conduit.
Examination drum outer wall is wound around the wide prestress band of 2.5cm at interval of 15cm from top to bottom, and prestress band is tire line.
The utlity model has following advantage:
The utility model provides a kind of energy to meet water salinity is risen and carries out the testing equipment of simulation test, the diameter of examination cylinder can exert an influence to the rising result of capillary water, for the capillary water rising situation of simulated field reality as much as possible, an examination cylinder diameter should be larger as far as possible.According to the simulation test requirement of 1:4, the internal diameter of having chosen each test cylinder in conjunction with the test maximum particle diameter of each soil sample and the supply standard of material is as follows.Bigbore testing equipment more can reflect actual conditions, and the test effect that is easy to observe is also a large feature of this test.The utility model draws rational water salinity lifting height, compared with method in specification sample moulding simple and with on-the-spot actual approaching, reading is accurate, the water level of bottom is constant.That this equipment has is reasonable in design, simple in structure, test the advantages such as accurate, for roadbed design provides science reliable data.
Brief description of the drawings
Fig. 1 is the utility model structural drawing.
In figure, 1-prestress band, 2-tries cylinder, 3-circular hole, 4-water delivering orifice, 5-base, 6-water inlet, 7-conduit, 8-flow controller, 9-tap bottle, 10-gas outlet.
Embodiment
