Description
Technical field
The utility model relates to a kind of slope stability simulation test equipment, but especially relates to a kind of supertronic than formula slope erosion instruction carriage.
Background technology
The destruction of side slope mainly contains two types, and the one, because the stability of side slope itself is not enough, As time goes on, side slope deforms and final unstability, forms integral body or localized landslip and destroys; Second, the stability of side slope own meets the demands, but side slope surface is because be exposed in the physical environment throughout the year, bearing the influence of various natural conditions, make side slope that various distortion, disease even destruction be taken place, wherein the souring of water is particularly evident, because current are to slope erosion, infiltration, make that shear resistance reduces between the slope soil particle, and the side slope that causes surface soil body unstable phenomenon is of common occurrence.The former can take into full account in design and be overcome, and the latter, namely rainwater but is unavoidable to the unstability that slope erosion produces.At loess slope domatic wash away, degrade phenomenon such as destruction, no matter be aspects such as design or maintenance, also do not have unified industry standard at present.
The western transport development project of Ministry of Communications was once studied at loess local highway High Slope Protection specially, and main achievement is used in the loess highway construction of provinces such as Shaanxi, Gansu, Ningxia.But, do not carry out deep research at the slope stability of loess slope; In recent years, the someone noticed the domatic destruction problem of loess slope, but did not obtain enough attention because its harm is little, do not become hot issue, so the document of this respect was also considerably less.And most research emphasis mainly are in the critical grade correlative study.
In fact, domatic destruction is not only aesthetic problem, and it will endanger side slope and sloping body stable condition, and then brings out side slope slope body and destroy.Therefore, for the side slope disaster is eliminated in bud, be necessary to carry out the side slope surface Study on Stability, and the research key of this respect is domatic measure problem, rainfall just is to the domatic ability of soaking, the research of producing husky system and washing away rule.Departments such as water conservancy, environmental protection and geology had once carried out long-term a large amount of research work, but these researchs mainly start with from water and soil conservation, environmental protection and diaster prevention and control angle, at domatic very slow natural hillside situation, explored the mechanical analysis and the test simulation that corrode.In recent years, someone to roadbed side slope wash away and seepage problem has been carried out experimental study work, tentatively grasped the certain law that roadbed side slope is washed away by surface water, align and confirm that the slope wash of knowledge loess slope is significant, but how to consider that rainfall destruction is domatic and then have influence on the whole slope stability of side slope, the research rainfall need be done further work to the domatic influence of washing away rule and side slope slope type being designed.These are operated in the scene and test the most effectively, also credible, become maximum obstacle but test difficulty and test funds.
For this reason, carry out the preferred option that large-scale model test becomes numerous researchists indoor, available technology adopting the water and soil conservation of a kind of Hydraulic for lifting load formula wash away the model test car, it is with reference to the dump truck principle, adopt the Hydraulic for lifting load device, vehicle body is similar to general automobile casing, and this instruction carriage is made up of vehicle frame, casing and hoisting apparatus three parts.Vehicle frame guarantees that by the fixing wheel shaft of crossbeam instruction carriage can move freely; Casing is welded to form by steel plate and square steel, and size can be determined according to the experiment place; Hoisting apparatus adopts lifting jack, is fixed in frame cross.Its shortcoming mainly contains: 1, vehicle frame is too high, consuming time, consumption power when dress soil; 2, the lifting jack lifting is height-limited, causes simulation side slope (slope) angle limited, generally can not be greater than 30 °; 3, the compbined test cost is too high.Also having adopted a kind of indoor mound to become gradient rain washout test model in addition in the prior art, is in the compacting of indoors artificial mound, sloping than cutting the slope according to different side slopes afterwards, forms the washout test model.Its shortcoming mainly contains: 1, be subjected to place restricted problem serious; 2, the conversion slope is bigger than difficulty; 3, test efficiency is low excessively; 4, the compbined test cost is too high.
The utility model content
Technical problem to be solved in the utility model is: but provide a kind of supertronic than formula slope erosion instruction carriage, solved lab simulation loess slope rainfall erosion damage process testing demand, solved the limited problem in model test place, convertible slope greatly reduces the model test cost than finishing various slope erosion tests.
For solving the problems of the technologies described above, the technical solution of the utility model is: but supertronic is than formula slope erosion instruction carriage, comprise vehicle frame, be hinged with casing on the described vehicle frame, the top of described casing has uncovered, also be provided with on the described vehicle frame for the hoisting apparatus of regulating described casing angle, described hoisting apparatus comprises by securing member and detachably is installed on portal frame on the described vehicle frame, the crossbeam of described portal frame is provided with first steel loop, described first steel loop is chain sling stiff end hook fixedly, the top of described casing is provided with second steel loop, and described chain sling movable end is connected with second steel loop by hook, and the below of described casing is provided with rain trap.
Preferably, an end of described vehicle frame is provided with the hand push handle, and the bottom of described vehicle frame is provided with travel mechanism.
