In view of this, the utility model provides a symmetry pressure-bearing diaphragm soil pressure cell.
The utility model provides a symmetry pressure-bearing diaphragm soil pressure cell, including casing, pressure-bearing diaphragm and pressure detecting element, the casing is the drum structure, the pressure-bearing diaphragm be with the disc structure of casing looks adaptation, it is equipped with two to coaxial setting is in respectively the both ends of casing, and with the connection can be dismantled to the casing, every the inboard of pressure-bearing diaphragm all is equipped with the pressure detecting element.
Furthermore, a supporting circular truncated cone matched with the shell is coaxially arranged in the shell, an annular boss matched with the shell is coaxially arranged on the inner side of the pressure-bearing membrane, and a sealing ring is coaxially arranged on the outer side of the annular boss.
Furthermore, the pressure detection unit is a resistance strain gauge, the inner side of each pressure-bearing membrane is provided with a plurality of resistance strain gauges, the side wall of the shell is provided with a through hole inside the shell, and a sealing element is detachably arranged at the through hole.
Further, the sealing element is a hollow bolt.
The utility model provides a beneficial effect that technical scheme brought is: the utility model discloses a setting up the pressure-bearing diaphragm at casing both ends symmetry, eliminated the error that soil pressure cell structure arouses because asymmetry in soil pressure measurement direction, make the inside soil pressure value of the soil body that records more accurate. The detachable connection mode of the pressure-bearing diaphragm and the shell can facilitate the assembly of the soil pressure cell.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be further described below with reference to the accompanying drawings.
Referring to fig. 1 to 3, an embodiment of the present invention provides a symmetric pressure-bearing diaphragm soil pressure cell, including a casing 10, a pressure-bearing diaphragm 20 and a pressure detection unit 30, where the casing 10 is a cylindrical structure, the pressure-bearing diaphragm 20 is a disc structure adapted to the casing 10, and has two pressure-bearing diaphragms 20, which are respectively and coaxially disposed at two ends of the casing 10 and detachably connected to the casing 10, and each pressure-bearing diaphragm 20 is provided with the pressure detection unit 30 on its inner side.
The utility model discloses in, after finishing with the equipment of pressure-bearing diaphragm 20 earlier, bury in the soil body again to detect the inside pressure of soil body through pressure detecting element 30 on the pressure-bearing diaphragm 20. The utility model discloses a setting up pressure-bearing diaphragm 20 at 10 both ends symmetries of casing, eliminated the soil pressure cell structure because the error that asymmetry arouses on soil pressure measurement direction, make the inside soil pressure value of the soil body that records more accurate. The detachable connection of the pressure-bearing diaphragm 20 and the housing 10 can facilitate the assembly of the soil pressure cell.
In the above embodiment, the supporting circular truncated cone 11 adapted to the housing 10 is coaxially disposed inside the housing 10, the annular boss adapted to the housing 10 is coaxially disposed inside the pressure-bearing diaphragm 20, and the sealing ring 22 is coaxially disposed outside the annular boss.
The utility model discloses in, the outside of annular boss is opened and is used for installing sealing washer 22 to have an annular recess, and wherein, sealing washer 22 is rubber seal, installs back on casing 10 when pressure-bearing diaphragm 20, and its annular boss that corresponds is close to one side and the 11 butt of support round platform that support round platform 11, under sealing washer 22's effect, realizes that pressure-bearing diaphragm 20 is fixed with being connected of casing 10. Wherein, the sealing rubber ring not only plays the sealed effect of water proof but also plays the fixed spacing effect of pressure-bearing diaphragm 20. The supporting round table 11 is disposed at the middle inside the housing 10.
In the above embodiment, the pressure detecting unit 30 is a resistance strain gauge, a plurality of resistance strain gauges are disposed on the inner side of each pressure-bearing membrane 20, a through hole is disposed on the side wall of the casing 10, and a sealing member 50 is detachably mounted at the through hole.
The utility model discloses in, the fixed mode to resistance strain gauge and pressure-bearing diaphragm 20 does not restrict. Specifically, all be equipped with 4 resistance strain gauges on every pressure-bearing diaphragm 20, and in practical application, can increase the quantity of resistance strain gauge as required to reach the purpose that improves soil sample pressure testing result precision. The leads of the resistance strain gauges extend out of the shell 10 from the through holes to be electrically connected with the pressure signal collecting device. And the sealing member 50 is used to seal the through-hole. The through hole is arranged in the middle of the side wall of the shell 10, and comprises a first through hole arranged on the side wall of the shell 10 and a second through hole 122 arranged on the supporting circular truncated cone 11, and the first through hole is communicated with the second through hole 122.
