Problems solved by technology

However, since Taihu Lake is located in the middle and lower reaches of the Yangtze River, it has the characteristics of vast water surface, rapid water flow, and strong wind and waves during the flood season. Mountain sides with vehicle transportation channels and slopes with a slope greater than 45 degrees, as well as side dikes for land reclamation, are difficult to transport building materials and personnel to construct. Therefore, how to use new technologies can prevent Taihu Lake from being scoured by long-term water flow, wind and waves. Erosion, intensified water and soil loss and other factors will cause the embankment of the lake bank to be easily unstable, and can gradually improve the ecological environment of Taihu Lake, a kind of bank revetment design scheme and construction method that is harmonious between man and nature

Embodiment 1

[0022] Such as figure 1 Shown, the present invention adopts the grass-green binge mesh ecological gabion of PVC protective layer, in cross-section is 30cm * 30cm square rectangular parallelepiped stone cage, artificially fills the pebble stone block of 3-5cm, is 45cm * 45cm square in cross section The cuboid gabion is artificially filled with 5-10cm pebbles and stones. The filling of the stones is carried out in sections, and then the upper opening is sealed tightly after completion.

[0023] Install double rows of bamboo piles at a distance of 3 meters from the lakeshore, with a distance of 120cm and a distance of 45cm between the piles and nails. The piles and nails go deep into the soil 50cm, and then use a hoisting boat to install stacking gabions between the double rows of bamboo piles and fill them with 5-10cm pebbles. The gabions are arranged and piled up on the outside of the dam (near the center of the river), and the gabions filled with 3-5cm pebbles are arranged and...

Embodiment 2

[0026] Such as figure 1 Shown, the present invention adopts the water-white gabion net ecological gabion of PVC protective layer, in the cuboid gabion of 30cm * 30cm square in cross section, artificially fills the pebble stone block of 3-5cm, is 45cm * 45cm square in cross section The cuboid gabion is artificially filled with 5-10cm pebbles and stones. The filling of the stones is carried out in sections, and then the upper opening is sealed tightly after completion.

[0027]Two rows of wooden piles are installed at a distance of 2 meters from the lakeshore, with a distance of 120cm and a distance of 50cm between the piles and nails. The piles go deep into the soil by 40cm, and then a stacking gabion is installed between the double rows of wooden piles by a hoisting boat and filled with 5-10cm pebbles. The gabions are arranged and piled up on the outside of the dam (near the center of the river), and the gabions filled with 3-5cm pebbles are arranged and piled up in the middle...

Embodiment 3

[0030] Such as figure 1 Shown, the present invention adopts the grass-green gabion net ecological gabion of PVC protective layer, and in the cuboid gabion of 30cm * 30cm square in cross section, artificially fills the pebble stone block of 3-5cm, is 45cm * 45cm square in cross section The cuboid gabion is artificially filled with 5-10cm pebbles and stones. The filling of the stones is carried out in sections, and then the upper opening is sealed tightly after completion.

[0031] Install double rows of thermoplastic polyvinyl chloride (PVC) resin piles at a distance of 1.5 meters from the lakeshore, with a distance of 120cm and a distance of 55cm between piles and nails. Cages, the gabions filled with 5-10cm pebbles are arranged and piled up on the outside of the embankment (near the center of the river), the gabions filled with 3-5cm pebbles are arranged and piled up in the middle and inside of the embankment (near the bank), the inner and outer gabions and piles The steel w...

Abstract

The invention provides a Taihu lake ecological dam revetment construction method. Gabion net ecological gabions are adopted, are manually filled with stone blocks, and are ranged and accumulated in positions with a distance being 1 to 5m away from a lake bank, in addition, double-row anchoring pile anchoring is implemented for building an ecological dam, the surface of the ecological dam is 30 to 60cm higher than the water level, a position between the ecological dam and the original lake bank is directly filled with river sediment, local native grass tree plants for beautifying the environment are planted on the ecological dam and the filled river sediment zone for forming a landscape wall, the peripheral ecological environment and the water quality condition of a revetment can be improved, the ecological revetment with the landscape function is achieved, so that unique Taihu lake landscape can be formed. The Taihu lake ecological dam revetment manufactured by the method has various advantages of good ecological performance, water permeability, flexibility, impact resistance, wave resistance and the like.

Description

technical field [0001] The present invention relates to water environment basins of Taihu Lake and rivers, belongs to the industry of water conservancy and municipal engineering, and is specifically aimed at the protection of bottom protection, slope protection, slope foot and other aspects of Taihu Lake and river dams, so as to further improve the ecological environment of Taihu Lake and rivers, and provides a The invention discloses a construction method for embankment revetment of an ecological dam in Taihu Lake. Background technique [0002] At present, in the Taihu Lake and river basins of our country, the traditional river revetment design structure generally only considers the flood control, water diversion, drainage, water storage and shipping functions of the river, and seldom considers the ecological function of the river. Therefore, most of the revetment structures of the river adopt Rigid hard materials such as masonry stones or concrete have destroyed the ecolog...
