The piston tube 3 is located at the upper end of the second cavity 21, and one end of the piston tube 3 is fixedly connected with the bottom of the detection block 1. 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 side wall surface of the piston tube 3 is provided with through holes 33, and the through holes 33 communicate with the second chamber 21 and the third chamber 31, respectively.
When using, a plurality of sleeves need to be used to the fabricated building, with every sleeve respectively with piston tube 3 intercommunication simultaneously, second cavity 21 communicates with third cavity 31 through-hole 33 this moment, third cavity 31 communicates with first cavity 11 again for second cavity 21 and first cavity 11 intercommunication, and then make second cavity 21 and external intercommunication. Then, grouting is performed into the sleeve through grouting equipment, the liquid level in the sleeve continuously rises, the grout rises into the second cavity 21 of the pressure detection part 2 and then rises along the second cavity 21, and the grout drives the piston 32 to move upwards. When the piston 32 rises to the through hole 33, the through hole 33 is blocked by the piston 32, or when the piston 32 rises to exceed the through hole 33, and the piston 32 is abutted against the bottom of the detection block 1 at the moment, namely, the piston 32 can not move upwards any more, and at the moment, the second cavity 21 is blocked by the piston 32 with respect to the first cavity 11, the second cavity 21 is not communicated with the first cavity 11, and at the moment, the second cavity 21 is a closed space.
The pressure detecting part 2 transmits the detected pressure to the corresponding signal processor 4 in real time, the signal processor 4 transmits the processed pressure signal to the corresponding control part 8, the higher the height of the slurry in the second cavity 21 is, the larger the pressure value detected by the pressure detecting part 2 is, and when the pressure detected by the pressure detecting part 2 exceeds a preset value, the piston 32 cannot move upwards any more at this time, and the slurry cannot rise any more. When the pressure detection pieces 2 of the grouting sleeve grouting pressure detection plugs connected with all the sleeves detect that the pressure exceeds a preset value, the situation that the liquid level of the grout in all the sleeves reaches a preset height is shown, the controller sends corresponding signals to grouting equipment, and the grouting equipment stops grouting into the sleeves.

That is, at this time, the piston 32 cannot move upward any more, and since the piston 32 blocks the through hole 33 and the second chamber 21 is separated from the first chamber 11, the slurry level in the second chamber 21 cannot rise any more. Meanwhile, the pressure detection pieces 2 detect the received pressure in real time and transmit the pressure to corresponding controllers, the second cavity 21 is filled with the slurry, the pressure value detected by the pressure detection pieces 2 exceeds a preset value, and when the pressure values detected by all the pressure detection pieces 2 exceed the preset value, the controllers send corresponding control signals to grouting equipment to stop grouting, so that the pressure in the sleeve is detected in real time, the automation of the sleeve grouting process is realized, and the sleeve grouting quality is ensured.
Further, as shown in fig. 1 and 2, the diameter of the piston tube 3 is larger than that of the first chamber 11, and the center line of the piston tube 3, the center line of the through hole 33, and the center line of the first chamber 11 coincide with each other. When the grouting device is used, one end of the piston pipe 3 is fixedly connected with the lower end of the detection block 1, the diameter of the piston pipe 3 is larger than that of the first cavity 11, the piston pipe 3 can separate the upper end of the second cavity 21 from the first cavity 11, so that the second cavity 21 can be communicated with the first cavity 11 only through the third cavity 31, whether the second cavity 21 is communicated with the first cavity 11 or not is conveniently controlled through the piston 32, when the second cavity 21 is not communicated with the first cavity 11, the slurry liquid level can not rise any more, and the pressure detection piece 2 detects that the pressure value exceeds the preset value at the moment, and grouting can be stopped; when the second cavity 21 is communicated with the first cavity 11, the air pressure in the second cavity 21 is consistent with the atmospheric pressure, and the liquid level of the slurry can continuously rise, so that the automation of the sleeve grouting process is realized, and the grouting quality of the sleeve is ensured.
