Example Embodiment

[0023] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0024] Such as figure 1 , 2 , 3, 4 show:

[0025] The invention is mainly suitable for small and medium-sized straight rivers, and the construction steps are as follows:

[0026] The original river bed along both sides of the river bank slope 1 ( figure 2 (Shown by the dotted line in the middle) two rows of wooden piles 13 are nailed up, and a mixture 2 composed of soil and gravel is filled between the bank slope and the wooden piles 13 from the bottom to the upper layer to form a new river bed 3; from the hard bank 19 (Bank slope) Gabion groin 7 is set obliquely toward the middle of the river course to only 1 / 3 of the width of the river course; a number of clean water creeks 4 are dug on the new river bed 3, the clean water creek 4 is composed of gravel 15, and the bottom of the river bed Located below the low water level, the water body of the river fl...

Abstract

The invention relates to a small and medium straight river longitudinal winding form construction method which comprises the following steps: two sides of a riverway bank slope are enclosed by wooden piles, mixture is filled between the piles and the riverway bank slope from the bottom layer to the upper layer to form a new river bed, and a main river groove is formed between two rows of wooden piles; willow bundles or rock filled gabions are placed at one side of the new river bed of the two rows of wooden piles; riprap is placed at one side of the main river groove; a gabion nail dam is arranged in a riverway slantly from the bank slope to the middle of the riverway; and a plurality of clear water creeks are excavated on the new river bed and aquatic plants are planted. The method solves the detects of extinction of various species and the like as an artificial straight river is not suitable for survival and growth of a plurality of animals, especially the inhabitation and egg reproduction fields of the aquatic animals are limited. With the invention, water body is effectively purified, the environmental quality of the river water is improved, a better inhabitation place is provided for various aquatic animals, different water flow states are formed, the requirements of various aquatic animals are met, the original function of the riverway is not influenced, and the integration of dirt purification and flood control is realized.

Description

technical field [0001] The invention relates to a medium and small straight river, in particular to a method for constructing a longitudinal meandering form of a medium and small straight river. Background technique [0002] With the continuous increase of the social population and the shortage of land area, the river channel has gradually evolved from a natural soil slope to a rectangular and trapezoidal excavation in the cross-sectional direction; be straight. Such changes increase the effective area of ​​land use, but seriously damage the aquatic ecosystem and water landscape environment of the river, especially the lining of concrete and mortar block stone slopes seriously damage the aquatic ecosystem. At the same time, the flattening of the river bed makes the river lack natural shoals and deep pools, and makes fish, amphibians, insects, birds and other animals and microorganisms closely related to human survival lose their good habitat, reproduction and refuge. place...
