Problems solved by technology

After the intercepting material is discharged into the river, it is affected by the buoyancy of the water and the impact force of the river bottom water, which makes it easy for a part of the intercepting material to be in an unstable state underwater, so it is washed away by the high-speed water flow. The interception material makes the embankment easy to lose its foundation in a critically stable state. Once the foundation is unstable, the embankment collapse will occur, causing construction workers to be injured, and dump trucks to fall into the river, resulting in property losses.

Embodiment Construction

[0008] see figure 1 and figure 2 , the present invention uses a steel cable 3 to connect the reinforced concrete frame 1 and the concrete tetrahedron 5 in series, and the two ends of the steel cable 3 are respectively fixed on the metal ring 2 of the concrete frame and the metal ring 4 of the concrete tetrahedron, and 8 represents the direction of water flow . During the closure period, according to the engineering needs, use loading machinery to load multiple dump trucks into the reinforced concrete frame 1 and concrete tetrahedron 5 connected in series. When hoisting, the reinforced concrete frame 1 is placed in front of the vehicle bucket, and the concrete tetrahedron 5 is behind, so as to ensure that when the dump truck unloads, the concrete tetrahedron enters the river first. After the dump truck travels to the closure embankment 7, facing the upstream of the front end of the closure embankment, travels along the reversing driving line 6 to the unloading site, then sta...

Abstract

The present invention relates to closure engineering technology and is especially method of preventing cut-off materail from being washed away. Steel reinforced concrete framework and concrete tetrahedron connected together with steel cable are hoisted, conveyed and unloaded into water before banquette repeatedly to form stable underwater banquette. The concrete tetrahedron with large weight and the framework with high stability make the connected structure incapable of being washed away, and many connected structure can form stable underwater banquette and prevent cut-off banquette from collapsing.

Description

technical field [0001] The present invention relates to a method for preventing washout of intercepting material. Background technique [0002] At present, materials such as block stones, gabions, and concrete tetrahedrons are commonly used to intercept rivers in interception projects at home and abroad. During the construction of the vertical block and interception, trucks are used to transport the intercepted materials to the vicinity of the embankment, and then reverse the vehicle on the embankment to drive to the edge of the embankment, unload the intercepted materials into the river, and a fleet of dump trucks goes round and round The interception material is discharged into the river water, and the river is gradually cut off. However, during the closure construction process, when the dragon mouth gradually shrinks, the flow velocity of the water flow gradually increases. After the intercepting material is discharged into the river, it is affected by the buoyancy of t...
