A third cavity 31 communicated with the first cavity 11 is arranged in the piston tube 3, a piston 32 matched with the third cavity 31 is arranged in the third cavity 31, and the piston 32 moves up and down along the third cavity 31. The piston tube 3 is provided with a through hole 33 on a side wall surface thereof, and the through hole 33 communicates with the second chamber 21 and the third chamber 31, respectively.
When the assembled building is used, a plurality of sleeves are needed to be used, each sleeve is respectively and simultaneously communicated with the piston tube 3, at the moment, the second cavity 21 is communicated with the third cavity 31 through the through hole 33, the third cavity 31 is further communicated with the first cavity 11, the second cavity 21 is communicated with the first cavity 11, and then the second cavity 21 is communicated with the outside. Then grouting is carried out in the sleeve through grouting equipment, the liquid level in the sleeve continuously rises, the slurry rises into the second cavity 21 of the pressure detecting piece 2, then rises along the second cavity 21, and the slurry drives the piston 32 to move upwards. When the piston 32 rises to the position of the through hole 33, the piston 32 blocks the through hole 33, or when the piston 32 rises to the position beyond the through hole 33, the piston 32 is abutted with the bottom of the detection block 1 at the moment, namely, the piston 32 can not move upwards any more, the space between the second cavity 21 and the first cavity 11 is blocked by the piston 32, the second cavity 21 is not communicated with the first cavity 11, and the second cavity 21 is a closed space at the moment.
