Description
Technical field
The utility model relates to geotechnical investigation field, is specifically related to a kind of hole pressure touching methods probe vacuum degassing device.
Background technology
Static sounding be the taper shape probe of some sensors that utilized to install in the soil body with accurate static(al) at the uniform velocity injection time every stress data of gathering come in real time, a soil in-situ method of testing of continuous print reflection soil property variation characteristic.Its test parameter of usually said static sounding is static point resistance and sidewall friction power.
Hole pressure (pore water pressure) static sounding adds the measurement function to soil body pore water pressure on the basis of conventionally test parameter.When popping one's head in by injection to the soil body to be measured, the pore water in the soil body press by permeable hole and hole and is conducted storehouse and be communicated with, and the pore water pressure of the soil body is delivered to the sensor for pore water pressure of inside of popping one's head in, passing hole pressure sensor and subsequent conditioning circuit can obtain pore water pressure force value.
Before carrying out hole pressure touching methods test, must carry out the saturated process of vacuum degassing to hole pressure touching methods probe, this ensures the key to the pore water pressure Measurement accuracy of the soil body.Hole pressure touching methods without the saturated process of vacuum degassing is popped one's head in, often large quantity of air is contained in pressure conduction storehouse, its hole and permeable hole, and the volume compression ratio of air and liquid is up to 100 to 1000 times, if the air in pressure conduction storehouse, hole and permeable hole is not drained, the variable quantity of soil body Pore Pressure can transmit the volume change being converted into air in way, makes sensor for pore water pressure cannot obtain the most real pore water pressure force value.
Utility model content
For solving the problem that hole pressure touching methods probe carries out the air in pressure conduction storehouse, hole and permeable hole to be drained when vacuum degassing is saturated to be processed, the utility model provides a kind of novel vacuum degassing device, structure is simple, easy to use, can improve the accuracy that probe detects.
The technical solution of the utility model is: described device comprises hole pressure touching methods probe, vacuum storehouse, pressure meter, vacuum pump, base, saturated solution is filled with in described vacuum storehouse, described hole pressure touching methods probe is located in vacuum storehouse, described base is provided with slideway, described slideway is provided with and can coordinates along slideway the slide block slided, described slide block and vacuum storehouse are connected through the hinge, and described vacuum pump is connected with pressure meter by tracheae, and described pressure meter is connected with vacuum storehouse by tracheae.
As preferably, vacuum Cang Dibuwaicebi is located at by described hinge.
As preferably, described vacuum storehouse is provided with the valve be connected with tracheae.
The beneficial effects of the utility model are: this device can make hole press probe and liquid level to be in parastate, the hole of both sides permeable hole and centre is made to press conduction storehouse to be in genesis analysis, then bubble is more conducive to tap pressure conduction storehouse under buoyancy and true hole air-extraction function, improves the discharge rate of air.This apparatus structure is simple, easy to operate, can improve the accuracy that probe detects.

Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the present embodiment comprises hole pressure touching methods probe 4, vacuum storehouse 2, pressure meter 6, vacuum pump 1, base 10, saturated solution 3 is filled with in vacuum storehouse 2, hole pressure touching methods probe 4 is located in vacuum storehouse 2, base 10 is provided with slideway 7, slideway 7 is provided with and can coordinates along slideway the slide block 9 slided, and slide block 9 is connected by hinge 8 with vacuum storehouse 2; Vacuum pump 1 is connected with pressure meter 6 by tracheae, and pressure meter 6 is connected with vacuum storehouse 2 by tracheae.
In the present embodiment, vacuum storehouse 2 bottom outside wall is located at by hinge 8, and vacuum storehouse 2 is provided with the valve 5 be connected with tracheae.
As shown in Figure 4 and Figure 5, adopt and pop one's head in vertically or angled manner exhaust, due to the buoyancy of saturated solution, part bubble 11 can remain in pressure conduction storehouse, hole and can not discharge.As depicted in figs. 1 and 2, when using this device to carry out the saturated process of vacuum degassing, vacuum storehouse is moved right along slideway, and be rotated counterclockwise vacuum storehouse to level, so just make hole pressure touching methods pop one's head in and be in level, the pressure conduction storehouse 41, hole of probe test side and the permeable hole 42 of both sides are in genesis analysis, as shown in Figure 6.So when carrying out the saturated process of vacuum degassing, bubble in pressure conduction storehouse, hole and permeable hole is constantly discharged from the permeable hole of top under the air-extraction function of saturated solution buoyancy and vacuum pump, owing to adopting the exhaust passage making probe front end in this way, namely hole pressure conduction storehouse is identical with the direction of saturated solution buoyancy with the passage that permeable hole is formed, therefore, it is possible to discharged by the bubble in pressure conduction storehouse, hole and permeable hole to greatest extent, ensure the precision of hole pressure touching methods probe when detecting.
In sum, the utility model by arranging slideway on base, and slided and can rotate to level in vacuum storehouse and the hinged vacuum storehouse that enables of slide block on base, hole pressure touching methods is popped one's head in and is in level thus makes hole press conduction storehouse to become vertical state with the exhaust passage that permeable hole is formed, thus better air is discharged by the buoyancy of saturated solution and vacuum suction effect.
