Problems solved by technology

Due to the buoyancy of the water and the impact of the river bottom water after the interception material is discharged into the river, it is easy to produce a part of the interception material in an unstable state underwater, and thus be 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

[0010] see Figure 1 ~ Figure 3 , During the closure period, the present invention lifts the A-type and B-type reinforced concrete special-shaped structure frame to the truck, transports it to the dike 13 by the car, and unloads it to the front end of the dike. A-type reinforced concrete special-shaped structure frame is composed of frame body 1, double interception arms 2 fixedly connected to frame body 1, connecting rod 4 fixedly connected to frame body 1 and two supporting legs 3, and connecting rod 4 is provided with Connecting jack 5; B-type reinforced concrete special-shaped structure frame is made up of frame body 6, double intercepting arm 7 fixedly connected on frame body 6, connecting rod 10 and connecting block 8 fixedly connected on frame body 6, connecting rod 10 A connection jack 11 is provided on the top, and a connection jack 9 is provided on the connecting block 8 . According to the needs of the project, one A-type and multiple B-shaped special-shaped structu...

Abstract

A method for preventing collapse of cut-off dyke is characterized by that several shaped reinforced concrete frames, which has one interception arm and more than two supporting legs, are interconnected and arranged on the front slope of said dyke in such manner that their legs are inserted in river bed, and the cut-off material is arranged in the water around said frames.

Description

technical field [0001] The invention belongs to the technical field of closure engineering, and in particular relates to a method for closure and embankment collapse. 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. Due to the buoyancy of the water and the imp...
