Stake pedosphere face soil and pore water pressure testing arrangement

The utility model belongs to the technical field of building construction equipment, a stake pedosphere face soil and pore water pressure testing arrangement is related to, on the prestressed concrete pipe pile lateral wall that excels in different cross -sections and stake end punishment do not embedded symmetry install silicon pressure drag formula soil pressure meter and silicon pressure drag formula pore pressure cell, the prestressed concrete pipe pile's that excels in inside of the top of opens has pile body drilling, the armor optical cable passes through pile body drilling and communicates with YE2539 high speed statical strain indicator, prestressed concrete pipe pile's the stake end of excelling in adopts the steel sheet back cover, and the silicon pressure drag formula soil pressure meter and the silicon pressure drag formula pore pressure cell of bottom install in the bottom of steel sheet, and the gauge head is down, division have on the steel sheet with armor optical cable complex hole groove, its simple structure is compact, and is small, and light in weight is with low costs, and convenient operation is sturdy and durable, has the good static characteristic that moves, and the range ability is wide, and measurement accuracy is high, and sensitivity is high, easily realizes the soil pressure of the stake pedosphere face department of next -door neighbour's pile body and pore water pressure's test.
