[0002] Aqueduct refers to an overhead water channel that conveys water across rivers, valleys, depressions and roads. It is commonly used for irrigation and water delivery, as well as for flood and sand drainage. Large aqueducts can also be navigable. Aqueducts are mainly built with materials such as stone masonry, concrete and reinforced concrete. Aqueducts in aqueduct projects are mostly prefabricated for installation and construction. There will be joint gaps at the joints between aqueducts, and joint joints need to be water-stopped. Traditional treatment methods mostly use impermeable concrete or waterproof mortar to seal the joints, which has a poor water-stopping effect and is prone to leaks at the joints.

By watching the displayed air pressure, personnel can accurately control the inflation and expansion.

[0028] Furthermore, the quick-card positioning and locking assembly includes a rectangular tube 11, and the adjacent ends of the two rectangular tubes 11 are both set as a blocking structure and are respectively fixedly connected to the tops of both sides of the U-shaped plate 2. An L-shaped rod 12 is slidably sleeved in the rectangular tube 11, and the repelling sides of the two L-shaped rods 12 are respectively fixedly connected to the adjacent sides of the two U-shaped handles. Two clamping blocks 15 are fixedly connected to the inner walls of the repelling sides of the two L-shaped rods 12, and the clamping blocks 15 are movably mounted in the corresponding transverse slots 102. Two positioning plug-in blocks 14 are fixedly connected to the bottom of the rectangular tube 11, and the positioning plug-in blocks 14 are movably mounted in the corresponding positioning slots 101.

[0029] Furthermore, the PLC network controller 7 is equipped with a wireless sending module for sending alarm information, and the wireless sending module is connected to the external background terminal; when the subsequent air pressure value leaks due to aging and other factors and becomes lower than the preset value, the PLC network controller 7 sends the alarm information to the background terminal through the wireless sending module, so that the personnel can be informed in time to carry out the air replenishment process.

[0030] The method of using this embodiment is as follows: before installing with the prefabricated groove 1, first pull the two U-shaped handles in the direction of repulsion, the two U-shaped handles drive the two L-shaped rods 12 to slide in the two rectangular tubes 11 and stretch the two springs 13, the two L-shaped rods 12 drive the clamping blocks 15 on both sides to repel displacement, at this time move the two U-shaped handles downward so that they drive the two rectangular tubes 11 to move downward through the two L-shaped rods 12, the rectangular tubes 11 drive the U-shaped plate 2 to move down into the two prefabricated grooves 1, the rectangular tubes 11 drive the corresponding two positioning blocks 14 to be stuck in the two positioning slots 101, the U-shaped plate 2 drives the U-shaped wear-resistant airbag 3 to move into the two prefabricated grooves 1, and is in the two prefabricated grooves 1. The joint of the groove 1 is sealed and shielded to stop water. After moving down, the tension on the two U-shaped handles is released. At this time, the elastic force of the two springs 13 in the stretched state drives the two L-shaped rods 12 to move close to each other. The L-shaped rods 12 drive the corresponding clamping blocks 15 to clamp into the transverse clamping grooves 102, so as to achieve clamping and locking of the U-shaped plate 2. When disassembling subsequently, the two U-shaped handles are pulled in the repulsive direction again, so that the clamping blocks 15 can be displaced outwards again to separate from the corresponding transverse clamping grooves 102 for unblocking, so that the quick-installation expansion-sealing water-stopping device body can be assembled and disassembled quickly and without tools by simply pulling and releasing the clamping, which is easy to operate and improves installation efficiency and convenience.

[0031] After installation, the personnel connect the air pipe joint 9 to the external inflation device, and use the external inflation device to inflate the U-shaped wear-resistant airbag 3 in one direction through the air pipe joint 9 and the one-way valve 8 in turn to make it expand. When the U-shaped wear-resistant airbag 3 expands, it is tightly pressed and sealed with the inner walls of the two prefabricated grooves 1 to enhance the sealing performance. The air pressure sensor 5 monitors the internal air pressure of the U-shaped wear-resistant airbag 3 in real time and transmits it to the PLC network controller 7 for display. The personnel can accurately control the inflation by watching the displayed air pressure. After filling with the appropriate air pressure, the external inflation device is closed. And it can be disassembled. Through the inflation method, the expansion force generated after inflation can be used to perform stable and long-term sealing, thereby improving the stability and long-term effectiveness of sealing and water-stopping. The alarm pressure value is pre-set using the PLC network controller 7. During long-term sealing and water-stopping work, when aging and air leakage occur, resulting in reduced sealing, the air pressure value will also decrease. When the air pressure drops below the preset value, the PLC network controller 7 sends an alarm message to the background terminal through the wireless sending module to alarm and remind personnel, so that personnel can be informed in time to carry out air replenishment processing.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
