每一只孔压计埋设后，应及时采用接收仪器检查孔压计是否正常；如发现异常应

After each pore pressure gauge is buried, the receiving instrument should be used to check whether the pore pressure gauge is normal; if an abnormality is found, the cause should be found and corrected or buried in time. <br>Before the piezometer is buried, it is necessary to measure and read the reading. After the piezometer is inserted into the hole, the reading is to be read again. After being pressed into the bottom of the hole, the reading must be read again. Among them, the first reading (frequency value) is compared with the fixed frequency to check whether the pore pressure gauge is normal; the second measurement reading is the static water pressure value at that time, which can be used as a stable initial reading, or after stable The comparison of the pressure values ​​determines the initial reading; the third reading measures the super-static pore pressure installed by the pore pressure gauge.

After each hole pressure gauge is buried, the receiving instrument shall be used in time to check whether the hole compenduses are normal;<br>Before the hole pressure gauge is buried, read the reading, wait to be put into the hole and then read the reading once, and so pressed into the bottom of the hole, you have to read the reading again. The first reading (frequency value) is compared with the rate-determined frequency to check that the hole pressure gauge is normal, the second reading measures the static water pressure value at that time, which can be used as a stable initial reading, or compared with the stable pressure value, to determine the initial reading, and the third reading measures the super static hole pressure installed by the hole pressure gauge.

After each pore pressure meter is buried, the receiving instrument shall be used in time to check whether the pore pressure meter is normal; if any abnormality is found, the cause shall be found out and corrected or buried in time.<br>Before burying the pore pressure gauge, first measure and read the reading. After putting it into the hole, measure and read it again. After pressing it into the hole bottom, measure and read it again. The first reading (frequency value) is compared with the calibrated frequency to check whether the pore pressure gauge is normal; the second reading is the hydrostatic pressure value at that time, which can be used as the stable initial reading, or compared with the stable pressure value to determine the initial reading; the third reading is the excess static pore pressure installed by the pore pressure gauge.<br>
