An ecological pipe bag submerged embankment and its filling method

Abstract

The invention relates to an ecological pipe bag submerged embankment, which includes an ecological pipe bag, a filled woven bag and a protective blanket. The protective blanket is laid on the river bed parallel to the river bank embankment, and both the ecological pipe bag and the filled woven bag are filled with sand. There are three ecological tube bags stacked in the shape of "pin" on the blanket, and the adjacent ecological tube bags in the axial direction are stacked in a staggered connection. The gaps between the three ecological tube bags are filled with filler braided bag. The invention can resist the long-term repeated impact of water flow, wind and waves, and fill the ecological pipe bag with sand and pile it up to form a high-strength, high-quality, high-density submerged embankment that is not suitable for collapse, and can maintain a relatively stable ecology of riverside water plants environment, reduce the impact of wind and waves on plants in the river bank water body, and stabilize the bottom conditions. At the same time, due to the landfill method of the present invention, the required materials are simple, and the landfill efficiency is high. The submerged embankment of the landfill can withstand the invasion of wind, waves and water flow, is not easily deformed and collapsed, and has strong operability in construction.

Description

technical field [0001] The invention relates to a protective submerged embankment, specifically an ecological pipe bag submerged embankment, and a landfill method thereof. Background technique [0002] A submerged dike is a commonly used coastal protection structure. The top surface of the structure is submerged underwater when the designed high water level is designed, and can be exposed to the water surface when the designed low water level is designed. It is usually a riprap submerged dike or a plug-in submerged dike. The top surface of the traditional riprap submerged dike is located in the area where the wave energy is most concentrated, and it bears relatively large wave loads, requiring a larger surface protection structure; in addition, the riprap submerged dike is a solid structure, which is prone to damage under the impact of waves. The phenomenon of hollowing out causes the submerged embankment to sink or collapse and lose its protective ability; and in some areas...

Problems solved by technology

The top surface of the traditional riprap submerged dike is located in the area where the wave energy is most concentrated, and it bears relatively large wave loads, requiring a larger surface protection structure; in addition, the riprap submerged dike is a solid structure, which is prone to damage under the impact of waves. The phenomenon of hollowing out makes the submerged embankment sink or collapse and lose its protective ability; and in some areas of our country, the geological conditions are poor, the stone materials are relatively scarce and the price is high, if the submerged embankment adopts a riprap structure, the project cost is relatively high

If the plate-type submerged embankment is used, it can effectively prevent the phenomenon of emptying, but the plate needs to be inserted to a sufficient depth, and the project cost is relatively high
