Soft foundation pore pressure meter embedding method
The invention discloses a soft foundation pore pressure meter embedding method which comprises the steps that first, a drilling machine is used for drilling; second, a pore pressure meter placed at the lowest position is pressed into a hole, and the steps are that 1. a probe of the pore pressure meter is wrapped in a filter membrane sleeve where medium-coarse sand is placed, and the medium-coarse sand covers a water filtering stone of the probe; one end of a nylon rope is tied to the middle portion of the pore pressure meter, and the embedding depth position is marked on the nylon rope; 2. a drill pipe is taken out, a drill bit is detached, and a sleeve is refitted; 3. the pore pressure meter is inserted into the sleeve, and the nylon rope is used for upward tight lifting; 4. the drill pipe is put downwards, the pore pressure meter is pressed into the hole, and the nylon rope is fixed; and 5. the drill pipe is taken out, and the pore pressure meter is hung at the designed embedding depth position; third, the steps 1-5 are repeated by multiple times, and pressing in of all pore pressure meters is completed; and fourth, soft soil backfill is carried out, so that all the pore pressure meters placed at the designed embedding positions and soft soil around are compact. The poses of the pore pressure meters can be accurately guaranteed, and the smearing effect of the soft soil on the pore pressure meters can be lowered.
