Description

Technical Field

[0001] The present invention relates to the technical field of channel slope repair, and particularly relates to a cofferdam device for repairing lining plates of a channel slope and an assembly method thereof. Background Art

[0002] Affected by complex geological conditions, high groundwater, floods, frost heaving and other factors, the lining plates on the channel slope are prone to various degrees of cracking, bulging, subsidence and other damage phenomena, which affect the water supply efficiency and water supply safety. Therefore, it is urgent to efficiently and high-qualityly complete the maintenance and repair construction of the channel slope lining plates. The existing maintenance and repair construction related to the lining plates is generally carried out under the water conveyance state.

[0003] At present, the technical solutions of the cofferdam devices for ensuring the maintenance and repair construction of the lining plates under the water conveyance state mainly fall into two categories: semi-enclosed type and slope-attached type. The semi-enclosed cofferdam is provided with a longitudinal cofferdam along the water flow direction, and transverse cofferdams are respectively arranged at the upstream and downstream. A U-shaped layout is formed by enclosing between the longitudinal cofferdam and the transverse cofferdams, and a construction dry area is formed on one side of the enclosed channel; as the name implies, the slope-attached cofferdam means that the device structure is closely attached to the channel slope surface. A seal is provided between the bottom of the device structure and the slope surface, and the top bears the water pressure, forming a sealed outer cover with a limited air height with the slope surface, so as to construct a semi-closed construction dry area.

[0004] However, both of the above two solutions have deficiencies. The semi-enclosed cofferdam scheme uses struts, tie rods and other methods to balance the lateral force generated by the water pressure on the cofferdam. This scheme has the operation safety risks of support instability and cofferdam overturning in the dynamic water operation. At the same time, the lateral force in this scheme increases linearly with the expansion of the operation width, which in turn leads to limited effective operation width along the water flow direction and cannot meet the large-area repair requirements; the slope-attached cofferdam is suitable for small-scale and rapid maintenance and repair work. Due to its semi-closed structure and low effective internal air height, there are major safety hazards. Once an accident occurs, it is very likely to cause major safety accidents similar to the water intake of underwater submersibles. At the same time, the water pressure on the top of this cofferdam is mainly resisted by the lining plate bearing pressure. The bearing capacity of the lining plate is limited, which determines that this cofferdam cannot be applicable to large-area repair requirements in terms of its structural form. Summary of the Invention

[0005] The purpose of the present invention is to overcome the defects and problems in the prior art that the cofferdam device cannot be applicable to large-area repair, and to provide a cofferdam device for repairing lining plates of a channel slope that can be applicable to large-area repair and an assembly method thereof.

[0016] An assembly method for a cofferdam device for repairing canal slope lining plates, the assembly method comprising the following steps:

[0017] S1. Place the water tank module on the upper side of the canal bottom along the water flow direction;

[0018] S2. Connect the first crawler module to one side of the water tank module, and then connect the two second crawler modules to one side of the two ends of the water tank module. The first crawler module is located between the two second crawler modules. Then splice the first crawler module and the two second crawler modules in sequence.

Finally, connect the frame module on the upper side of the two second crawler modules, and install a baffle on the upper side of the frame module. The baffle is flush with the upper end surface of the water tank module to form a flow-through area;

[0019] S3. Connect the two second crawler modules to the other side of the two ends of the water tank module, and then connect the frame module on the upper side of the two second crawler modules, and install a baffle on the upper side of the frame module. The baffle is flush with the upper end surface of the water tank module to form a construction dry area;

[0020] S4. Arrange sealing water bags at the bottom of the second crawler module and the water tank module, and then inject water into the sealing water bags. After the sealing water bags are inflated, they are in contact with both the canal bottom and the two canal slope lining plates. At this time, the assembly is completed.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In the cofferdam device for repairing canal slope lining plates and its assembly method of the present invention, through modularization, the flow-through area is designed as a semi-surrounding structure. The slope part is covered by the first crawler module. The first crawler module not only provides one surface of the semi-surrounding structure, but also can be used as a power device for underwater walking. The first crawler module forms a sealed semi-surrounding structure with the two end faces of the device and the side faces of the middle water tank module. The water pressure received by this semi-surrounding structure is balanced in the cross-sectional direction. Compared with the prior art, there is no need to add additional positioning supports on the device to balance the water pressure, solving the problem of unbalanced water pressure and being applicable to large-area repairs. Therefore, the present invention is not only applicable to large-area repairs, but also has a stable structure.

[0023] 2. In the equipment for repairing cofferdams of canal slope lining slabs and its assembly method of the present invention, both the first crawler vehicle module and the second crawler vehicle module adopt the connection method of support frames, which not only ensures the structural strength but also facilitates the connection between each module. The first crawler vehicle module and the second crawler vehicle are driven by water hydraulic motors, and the water hydraulic motors are driven by clean water without polluting the water source. By setting buoyancy water tanks, the pressure of the first crawler vehicle module and the second crawler vehicle module on the canal slope lining slabs can be reduced to avoid damaging the canal slope lining slabs due to excessive pressure. Therefore, the structure of the present invention is stable and the installation is convenient.

[0024] 3. In the equipment for repairing cofferdams of canal slope lining slabs and its assembly method of the present invention, both the frame module and the water tank module adopt truss structures. The frame module is in an inverted stepped shape, with a relatively stable structure, which is convenient for connecting between each module and makes the weight of the equipment lighter, facilitating the removal of the equipment after repairing the lining slabs. By setting a locking mechanism, after the water tank module is placed at the bottom of the canal, the two water tank modules can be automatically connected together through the locking mechanism, which is convenient for operation. Therefore, the structure of the present invention is stable and the operation is convenient.

[0025] 4. In the equipment for repairing cofferdams of canal slope lining slabs and its assembly method of the present invention, after passing the locking pin through the limit hole on the connection surface of the water tank module, control the locking pin oil cylinder to work, drive the support leg and the first support to rotate along the second support. After rotation, control the locking oil cylinder to work, so that the distance between the two water tank modules becomes smaller, and at the same time the locking pin is stuck outside the limit hole, and the two water tank modules are connected and locked. When it is necessary to separate the two water tank modules, only need to make the locking oil cylinder and the locking pin oil cylinder work in reverse in sequence, and then pull one of the water tank modules. After the locking pin passes through the limit hole, the two water tank modules are separated. Therefore, the structure of the present invention is stable and the installation and disassembly are convenient. BRIEF DESCRIPTION OF THE DRAWINGS
