River ecological bank protection system formed by triangular pyramidal wood pile stone cage frames and construction method

Abstract

The invention discloses a river ecological bank protection system formed by triangular pyramidal wood pile stone cage frames. First and second type wood pile stone cage frames are respectively fixed in a non-turning place and a turning place of a river channel, and respectively consist of three wood piles, gravels and nylon nets; a large gravel layer and a small gravel layer are arranged in the first type wood pile stone cage frame; and a large gravel layer, a small gravel layer, a ceramic particle layer and a charcoal coating layer are arranged in the second type wood pile stone cage frame. The construction method comprises the steps of: a) embedding of wood piles; b) binding of the wood piles; c) setting of nylon nets; d) filling of the first type wood pile stone cage frame; e) filling of the second type wood pile stone cage frame; f) planting of aquatic plants; and g) setting of artificial aquatic plants. The river bank protection system and the construction method thereof achieve an effect of river bank protection, and enhance the river self-purifying capacity and the multi-natural landscapes through an absorbing effect of the ceramic particle layer and the charcoal coating layer on nitrogen, phosphor and organic matters in water.

Description

technical field [0001] The present invention relates to a river ecological revetment system and construction method composed of triangular conical wooden pile gabion frame, more specifically, to a triangular conical wooden gabion that can not only prevent floods from scouring the river bank but also purify water quality. River ecological revetment system composed of pile gabion frame and its construction method. Background technique [0002] Many small and medium-sized rivers in my country have one-sidedly emphasized economic development in the reinforcement and renovation work, coupled with lagging governance concepts and other reasons, resulting in the current small and medium-sized rivers with serious river siltation, insufficient flood control capabilities, serious water pollution, changes in river channel shape, and rivers. The network water area is constantly shrinking and other problems. Today, when people and nature live in harmony and ecological concepts are increas...

Problems solved by technology

[0003] Traditional water conservancy project dam slope protection generally adopts natural stone masonry or cast-in-situ concrete; natural stone masonry slope protection has disadvantages such as difficult construction, difficult control of engineering quality, long construction period, and poor slope protection effect, and the mining of natural stone masonry is easy to damage the natural environment. Ecological environment; cast-in-place concrete slope protection has defects such as complex construction, low efficiency, poor flexibility and inability to adapt to foundation deformation, easy cracking and suspension, and is difficult to repair; and stone masonry and cast-in-place concrete slope protection deviate from ecological slope protection, and there will be engineering The construction time is long and the ecological benefits are delayed
