Description

Technical Field

[0002] Dredged sand filling bag refers to a method of constructing engineering structures by filling sand and soil produced in dredging projects into special geotextile bags. This method is widely used in waterway regulation, river bank reinforcement and other projects, and can effectively utilize dredged soil resources, reduce environmental pollution, and reduce engineering costs. The material in the filling bag is mainly dredged sand, which usually has good physical and mechanical properties, such as high density and low permeability. In practical applications, the dredged sand needs to be processed to meet engineering requirements, such as controlling clay content and adjusting water content. The existing river bank solidification structure usually uses long steel pipes or ropes for positioning when fixing dredged sand bags, which makes it very inconvenient to replace dredged sand bags when they are damaged, thereby increasing the difficulty of maintenance personnel's work, reducing work efficiency, and prolonging the time for river water to scour the river bank, which is easy to cause damage to the river bank. At the same time, the existing river bank solidification structure cannot increase the water interception height of the river bank during the flood season, which makes it easy for river water to flow back when the water level is high, and its use effect is not good.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) When the dredged sand filling bag body is damaged, the operator starts the motor inside the protective cover to run forward. When the motor runs forward, it drives the first sprocket to rotate along the first shaft seat on the positioning block. When the first sprocket rotates, it drives the second sprocket to rotate through the chain. When the second sprocket rotates, it drives the first shaft rod to rotate along the inside of the two first shaft sleeves.

When the threaded sleeve moves upward, it drives the clamping plate to move upward. When the clamping plate moves, it drives the first sliding block to slide along the inside of the first sliding groove, thereby increasing the stability of the clamping plate when it moves. When the clamping plate moves upward, the dredged sand filling bag body is loosened, so that the dredged sand filling bag body can be quickly disassembled for replacement.

[0015] When installing a new dredged sand filling bag body, the operator inserts the two ends of the dredged sand filling bag body into the two mounting frames respectively, and then the operator starts the motor in reverse.

[0016] (2) When the water level in the river is high, the operator starts the hydraulic cylinder inside the installation groove to push the moving seat to move. When the moving seat moves, the second sliding block is driven by the connecting block to slide along the inside of the second sliding groove, thereby increasing the stability of the moving seat when moving. When the moving seat moves, the baffle is pushed upward by the transmission rod. When the baffle rotates, it drives the rotating rod to rotate along the connecting frame, so that the baffle can be rotated and erected, thereby effectively preventing river water from flowing back.

[0017] (3) The river bank solidification structure is very convenient for disassembling and assembling dredging sand bags, thereby facilitating the replacement of damaged dredging sand bags, thereby reducing the difficulty of maintenance personnel's work, improving work efficiency, and reducing the time of river water scouring, effectively protecting the river bank. At the same time, it can increase the water-blocking height of the river bank to avoid river water backflow, and has a very good use effect. BRIEF DESCRIPTION OF THE DRAWINGS
