The advantages are that: the method can effectively prevent the damages of freezing and swelling force of northern lakes to the embankment, has the advantages of simplicity, obvious effect and low cost, does not need to dig a stress isolation ditch on ice in winter, does not need to repair the embankment in summer and autumn, and has practical guiding significance for protecting the embankment in winter in northern China and preventing the damage of the freezing and swelling force to the embankment.
Description
Technical Field
The utility model relates to a bank protection structure on ice top of lake bank winter in north belongs to lake bank ecological protection restoration technical field.
Background
In wetland parks, in the winter ice-sealing period in the north, the frost heaving force of ice forms great impact on the embankment, so that roads, trees and facility equipment of the embankment are extruded and damaged, the soil layer is brought into water by the ice and needs to be filled with rammed earth again, and the embankment needs to be dammed and repaired every year, so that great loss is caused. The damage to the north bank caused by the impact force is particularly huge, particularly after lake water is completely frozen, the frozen layer can expand for the second time along with the gradual warming of the air temperature, so that the large-area damage to the north bank can be caused, roads and vegetation on the bank can be damaged, and even buildings near the bank can be affected. The urban wetland restoration is a hot topic in recent years, and the related restoration technology is also very extensive. The method generally adopted for the damage to the north bank is as follows: after the lake water is completely frozen, a deep groove with the width of about 1 meter is dug along the trend of the bank at the position which is about 10 meters away from the north bank for unloading the stress of the secondary expansion of the frozen layer. This method, while effective, is time consuming and labor intensive and does not prevent the frost heaving forces that occur during the formation of ice from lake waters. There is currently no very effective safeguard against such bank damage due to ice frost heave.
Disclosure of Invention
The utility model aims at providing a bank protection structure on ice top of lake winter embankment in north that can play effectual guard action to lake winter embankment in north.
The utility model discloses a realize by following technical scheme:
the utility model discloses a cage is protected to metal, characterized by: the metal cage is a rectangular-frustum-shaped frame structure with a rectangular bottom and right-angled trapezoid side faces, the top of the metal cage is open, metal grids are arranged on other faces, the slope face of the metal cage is back to the bank and is arranged in lake water along the bank, the distance between the metal cage and the bank is not less than 1.8 m, the metal cage is filled with stones, and a ramming layer is arranged between the metal cage and the bank.
The inclination of the slope surface of the metal protection cage is 65-78 degrees;
the height of the metal protection cage is 1-2 meters, and the width of the lower bottom surface is 1-2 meters;
the particle size of stones filled in the metal protection cage is larger than 20 cm.
The utility model has the advantages that: the method can effectively prevent the damages of freezing and swelling force of northern lakes to the embankment, has the advantages of simplicity, obvious effect and low cost, does not need to dig a stress isolation ditch on ice in winter, does not need to repair the embankment in summer and autumn, and has practical guiding significance for protecting the embankment in winter in northern China and preventing the damage of the freezing and swelling force to the embankment.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic structural view of the metal cage.
In the figure: 1-metal cage protection, 2-stone, 3-rammed earth layer, 4-bank, 5-road on bank and 6-metal grid.
Detailed Description
Referring to the attached drawings, the utility model discloses a cage is protected to the metal 1, and the metal protects the cage and is the rectangular pyramid frame construction that is rectangle, side for right trapezoid with the bottom of 5 centimetres of angle steel preparation, and cage open-top is protected to the metal, and other faces all are equipped with metal grating 6, and metal grating forms with the direct 2 centimetres of steel reinforcement welding. The height of the metal protection cage is 1.03 m, the width of the lower bottom surface is 1.1 m, the length is 3 m, and the inclination of the slope surface is 75 degrees. The slope of the metal cage is back to the embankment 4 and is arranged in lake water along the embankment, the distance between the metal cage and the embankment is 2 meters, the metal cage is filled with stones 2 with the grain diameter larger than 20 centimeters, five metal cages are connected together to form a group to form huge resultant force to resist the extrusion of ice, a rammed soil layer 3 with the thickness of two meters is arranged between the metal cage and the embankment, the rammed soil layer in winter becomes a frozen soil layer to form buffer, the embankment behind and a road 5 on the embankment are protected, and the soil layer is prevented from being brought into water by ice after being extruded and melted by the ice.
