Foldable portable water filling surrounding well used for piping emergency rescue

Abstract

The invention provides a foldable portable water filling surrounding well used for piping emergency rescue. The foldable portable water filling surrounding well comprises a foldable enclosure protection structure, a water-proof and water-permeable structure and an auxiliary accessory. The foldable enclosure protection structure comprises an annular water bag, circumferential rings, a water inlet,a gas outlet, a water discharge port and guide rods. The water-proof and water-permeable structure comprises a water-permeable cushion layer, a waterproof layer and a fixing piece. The auxiliary accessory comprises a water discharge hose and a height gauge. The annular water bag of the foldable enclosure protection structure has multiple layers communicating with one another, and the water bag isfilled with water through the water inlet; and during installation, the foldable enclosure protection structure and the water-proof and water-permeable structure are laid flat around a piping openingand rise to the working height after water filling. The surrounding well structure with overall rigidity is formed by the foldable water bag provided with the circumferential ribs in a water filling manner; meanwhile, by means of the water-proof and water-permeable structure, seepage damage of the stratum around the piping position is prevented, and good integrity, leakproofness and stability areachieved; and the process is very simple, the structure is portable, the foldable portable water filling surrounding well can be carried by people, the emergency rescue speed and efficiency are high,and broad application prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of anti-seepage of water conservancy dams, in particular to a foldable portable water-filled enclosure for emergency rescue of piping and an application method thereof. Background technique [0002] Piping is one of the most common dangers of dams along rivers and rivers in our country during the flood season. The reason for this is that in the binary or multi-element soil structure in which the upper part of the dam is an aquitard and the lower part is a high-permeability layer, the flood causes the water head in the high-permeability layer. As the elevation rises, a higher hydraulic head difference produces greater seepage force, causing the fine particles in the bottom sand layer to be carried out by the water flow. If not rescued in time and allowed to develop, the sand layer under the embankment engineering foundation will be emptied, causing the embankment engineering to collapse suddenly, causing acci...

Bai Xiangchen et al proposed an anti-piping casing (ZL201821184540.X), using supports and casings to build a casing that can be flexibly arranged in shape, which can be applied to more complex terrain, but the support and casing need to be closed during assembly , which require high installation accuracy, anti-seepage materials should be set between the peripheral panels, and water seepage is easy during the assembly process

Mo Yuran proposed a water-filled reverse filter enclosure for flood fighting and emergency rescue (CN201610766745.8, ZL201620991562.1), whose cross-section is trapezoidal, and the sealing body formed after filling with water is used to store water, but the sealing body with trapezoidal cross-section The surface will bulge when it is in water, and it cannot form a predetermined shape; secondly, it needs electricity, pumps and laying a suction pipe to pump water when it is used. There is no backup measure under unfavorable conditions, and the lateral stiffness of the sealing body is very small during the water filling process, which is very unstable. ; Third, the circumferential rigidity is low, and the material strength of the sealing body can only be relied on to resist water pressure; Fourth, the water-filled reverse filter well does not perform seepage isolation treatment on the shallow surface, which may easily lead to the gushing out of the piping Water flows around the surrounding well from the bottom of the surrounding well to the outside of the surrounding well, expanding the damage of piping; finally, the height of the outfall is fixed, and the water level in the surrounding well cannot be flexibly controlled according to the actual situation during the rescue process
