Embodiment 1

[0032] refer to Figure 1-8 , the present embodiment provides a gravity pile for dam breach sealing, including a hoisting assembly, and a pile body assembly is detachably connected to the bottom of the hoisting assembly;

[0033] The pile body assembly includes a plurality of interconnected base bodies 1, and the side walls of the base body 1 are fixedly equipped with anchoring parts;

[0034] Substrate 1 comprises cube frame 105, and the side wall of cube frame 105 is fixedly provided with anchoring portion, and cube frame 105 edge portion is fixedly connected with trapezoidal plate 106, and trapezoidal plate 106 is positioned at cube frame 105 inner side, and trapezoidal plate 106 long base is fixed with cube frame 105. Then, the sides of adjacent trapezoidal plates 106 are affixed to each other, and the short bases of four adjacent trapezoidal plates 106 are connected end to end to form square holes 104. The surface of trapezoidal plates 106 is provided with some permeable ...

Embodiment 2

[0047] refer to Figure 9 , the difference between this embodiment and Embodiment 1 is that one steel pipe 23 is inserted into the earth-rock dam along the square hole 104, and the remaining steel pipes 23 are inserted into the earth-rock dam along the permeable hole 103, and the remaining steel pipes 23 are facing the same direction. This insertion scheme can be applied on the outermost substrate 1.

Embodiment 3

[0049] refer to Figure 10 , The difference between this embodiment and Embodiment 1 is that several steel pipes 23 are inserted along the permeable holes 103, and several steel pipes 23 face around the base 1.

Abstract

The invention relates to the technical field of breach plugging, in particular to a gravity pile for dam breach plugging, which comprises a hoisting assembly, and a pile body assembly is detachably connected below the hoisting assembly; the pile body assembly comprises a plurality of base bodies connected with one another, and anchoring parts are fixedly installed on the side walls of the base bodies. The base body comprises a cubic frame, anchoring parts are fixedly installed on the side walls of the cubic frame, trapezoidal plates are fixedly connected to the edges of the cubic frame and located on the inner side of the cubic frame, the long bottom edges of the trapezoidal plates are fixedly connected with the cubic frame, the side edges of the adjacent trapezoidal plates are fixedly connected, and the short bottom edges of the four adjacent trapezoidal plates are sequentially connected end to end to define a square hole. A plurality of water-permeable holes are formed in the surface of the trapezoidal plate, and a plurality of steel pipes are inserted into the water-permeable holes. The purposes that the pile forming structure is modularized, construction is convenient and fast, and the throwing object is effectively prevented from losing can be achieved.

Description

technical field [0001] The invention relates to the technical field of breach sealing, in particular to a gravity pile used for embankment breach sealing. Background technique [0002] my country's surface water system is developed, rainfall is abundant, and the coastal areas of large-scale water systems have been affected by flood disasters since ancient times. Building embankments and dams to prevent flooding has been an important livelihood project since ancient times. Beware of breakage is also a common accident when floods occur. Once there is a break in the defense, the lives and property safety of the people in the rear will be seriously threatened. The existing sealing measures for breaches are usually to put the blocking material into the fluid, gradually close the breach, and slow down the water flow. The falling distance of the object is long, and the traditional sealing method is often difficult to work. Therefore, for high-velocity and large-depth breaches, fo...
