Tubular storage and filling device for hydraulic mass concrete and its application

A use of a tubular storage and filling device for hydraulic mass concrete, applied in sluice crack control, comprising the following steps:

• S1:
• performing construction preparation;
• S2:
• performing foundation treatment;
• S3:
• constructing a sluice floor (10);
• and
• S4:
• constructing a pier (11), comprising:
• S41:
• performing construction layout;
• S42:
• binding and installing pier reinforcement (15);
• S43:
• erecting a pier formwork (17) above the sluice floor (10);
• S44:
• detachably installing the tubular storage and filling device for hydraulic mass concrete at a design position;
• wherein the tubular storage and filling device for hydraulic mass concrete comprises a filling body (b), and the filling body (b) comprises:
• an outer tube body (1);
• a bottom sealing plate (6), connected to a bottom end of the outer tube body (1), the bottom sealing plate defining at least one discharging port (7);
• a storage space (9), defined inside the outer tube body (1) and configured to store a material;
• an airbag (8), being inflatable and deflatable and located inside the outer tube body (1) above the bottom sealing plate (6);
• a gas pipe (4), disposed in the outer tube body (1), wherein a bottom end of the gas pipe (4) is connected to the airbag (8), and a top end of the gas pipe (4) extends above a top end of the outer tube body (1);
• a switch (5), disposed on the gas pipe (4) and be capable of being opened and closed;
• wherein when the airbag (8) is inflated, the airbag (8) is capable of completely blocking the discharging port (7), and when the airbag (8) is deflated, the discharging port (7) is capable of opening for discharging the material;
• an inner tube body (2), sleeved within the outer tube body (1), wherein a bottom of the inner tube body (2) is fixedly connected to the bottom sealing plate (6);
• the airbag (8) is sleeved on the inner tube body (2) and connected to an outer wall of the inner tube body (2);
• the gas pipe (4) is located within the inner tube body (2);
• and the storage space (9) is defined between the inner tube body (2) and the outer tube body (1);
• and
• a supporting piece (w1), disposed at a bottom of the outer tube body (1);
• wherein the bottom of the outer tube body (1) is defined with a slot (101) along a circumferential direction;
• and the supporting piece (w1) is engageable with the slot (101);
• S45:
• connecting the gas pipe (4) to an inflation device (18);
• opening the switch (5), activating the inflation device (18) to inflate the airbag (8) until the airbag (8) completely blocks the discharging port (7), then closing the switch (5), and disconnecting the inflation device (18);
• S46:
• casting, vibrating, and curing concrete;
• S47:
• filling the outer tube body (1) with a ductile material (13);
• and
• S48:
• after initial setting of the concrete, opening the switch (5) to deflate the airbag (8) and open the discharging port (7);
• releasing positional constraints, extracting the tubular storage and filling device for hydraulic mass concrete upward to form a cavity (12);
• simultaneously filling the ductile material (13) to the cavity (12) via the discharging port (7), achieving simultaneous tube extraction and cavity filling.
