Description
Technical Field
The invention relates to the technical field of sandy soil liquefaction judging devices, in particular to a sandy soil liquefaction judging device.
Background
The sandy soil liquefaction (liquefaction of sand) refers to the phenomenon that water-saturated loose powder and fine sandy soil are suddenly destroyed under the vibration effect to be in a liquid state, and the change phenomenon of the sandy soil from the solid state to the liquid state is caused by the reduction of effective stress due to the increase of the pore water pressure. The mechanism is that saturated loose powder, the fine sand soil body has the trend that the granule removes and becomes dense under the vibration effect, bearing to the stress turns to water from the sand skeleton, because the permeability of powder and fine sand is bad, the pore water pressure can sharply increase, when the pore water pressure is big to the total stress value, effective stress just falls to 0, the granule suspension is in aqueous, the sandy soil body takes place the liquefaction promptly, the sandy soil liquefaction is judged and is needed to use the device, among the prior art CN211505115U sandy soil liquefaction discriminating gear, through introducing the water body that the sandblast emits water in the water tank, and filter the water body through three basin, through the sand volume that filters that obtains in observing three basins at last, thereby can make preliminary judgement to the circumstances of sandy soil liquefaction, be convenient for people to make judgement to the circumstances of geological disasters, but the device still has following weak point:
1. in the using process of the device, the sand with water is filtered through the filter screen, so that the sand with water is slowly filtered due to the fact that the device is inconvenient for pressurizing the sand with water, the working efficiency is influenced, meanwhile, due to the fact that the device is inconvenient for pressurizing, the water in the sand is insufficiently filtered, and the judgment result has errors;
2. the device is when using, directly places the sand that has water in the filter-tank for the sand that has water has just filtered immediately, leads to the inaccurate sand that has water of going on putting into of going on carrying out the ration, leads to the volume that has the grit of pouring into in a plurality of filter-tanks to be unable fixed, leads to the result to be not convenient for compare.
