[0002] U-shaped hydraulic aqueduct is a hydraulic engineering structure made of concrete structure, usually used to divert or drain water between rivers, channels or other water bodies, divert water from one place to another, or control the direction and flow of water flow. It has the function of reducing the resistance of water flow, improving the stability of water flow, and also reducing the impact of water flow on the structure. In hydraulic engineering, U-shaped hydraulic aqueduct is widely used in various water diversion, drainage and irrigation projects.

[0003] The existing U-shaped hydraulic aqueduct inner mold is easily affected by external forces due to long-term use and the need to withstand concrete pouring pressure, which causes the mold to deform, resulting in difficulty in disassembly and requires additional manpower and time.

[0041] For example, in one embodiment: the inner walls of the lateral mold body 12 and the arc-shaped bottom mold 13 are both recessed with a plurality of grouting grooves for pouring concrete between the channel and the aqueduct inner mold assembly 10 .

[0042] For example, in one embodiment: when it is necessary to remove the mold, the four driving pulleys 224 will be started to drive the sliding installation assembly 20 to carry the bottom support assembly 30 and the two lateral assemblies 40 along the two lifting slide rails 21 to move to the inner mold assembly 10 of the aqueduct to be removed, and then the multiple bottom pressing cylinders 32 will be started so that the bottoms of the multiple bottom pressing cylinders 32 are respectively clamped on the tops of the multiple arc-shaped bottom molds 13, so that the driving sliding installation assembly 20 is temporarily clamped and stopped. Then the driving cylinders 521 in the multiple middle quick release devices 50 will be started so that the output shaft of the driving cylinder 521 is extended, the active driving rotating rod 522 is rotated, the first connecting rotating shaft 524 is rotated accordingly, the driving installation plate 525 is slid downward along the vertical sliding rod 517, and the connecting fitting element 53 is slid downward accordingly, until the clamping plate 534 enters the installation groove 14 in the middle of the lateral mold body 12, and the disassembly buckle 538 is clamped in the fixed clamping groove in the installation groove 14, and then the multiple end disassembly cylinders 4 are started. 11, so that the output shafts of the multiple end disassembly cylinders 411 are extended, so that the outer sides of the multiple end disassembly cylinders 411 are respectively clamped in the mounting grooves 14 at the top or bottom of the multiple lateral mold bodies 12, and the two lateral mold bodies 12 are clamped and fixed by two lateral components 40 respectively. Subsequently, the output shafts of the multiple end disassembly cylinders 411 are synchronously retracted, and at the same time, the output shafts of the multiple driving cylinders 521 are retracted, so that the two lateral mold bodies 12 will be clamped and pulled out synchronously, and the two lateral mold bodies 12 are automatically demolded. Subsequently, the output shafts of the multiple bottom pressing cylinders 32 are retracted, and the arc bottom mold 13 is clamped and pulled out, thereby realizing the automatic demolding of the aqueduct inner mold assembly 10 in batches and on a large scale.

[0043] For example, in one embodiment, when the lateral mold body 12 is deformed due to concrete pouring pressure or manual operation errors, and the mounting groove 14 is deformed accordingly, the plurality of reinforcement cylinders 544 are activated to extend the output shafts of the reinforcement cylinders 544, so that the sliding bar 541 and the reinforcement mounting plate 542 are synchronously moved downward along the vertical sliding groove 535, so that the top of the reinforcement airbag 545 is compressed, so that the gas in the reinforcement airbag 545 is gathered at its bottom, so that the hard surface formed on the outer side and the bottom surface of the reinforcement airbag 545 is moved downward, so that the elastic arc piece 546 is moved downward accordingly. And it is deformed, so that the bottom surface of the elastic arc piece 546 is more closely attached to the top surface of the clamping plate 534, providing support for the clamping plate 534, thereby preventing the subsequent extension of the output shaft of the driving cylinder 521, so that the clamping plate 534 enters the deformed mounting groove 14, presses the deformed mounting groove 14, and restores the mounting groove 14 to its original state. At the same time, the elastic arc piece 546 moves downward, which will cause the disassembly buckle 538 to slide downward along the buckle slide groove 537, so that the disassembly buckle 538 extends, so that the disassembly buckle 538 is better clamped into the fixed clamping groove in the mounting groove 14, thereby completing the clamping fixation.
