A permeable river T-shaped dam planted with artificial aquatic plants and its construction method

Abstract

The invention discloses a permeable artificial T-shaped dam for planting artificial seaweeds and a construction method thereof. The permeable artificial T-shaped dam for planting artificial seaweeds comprises timber piles uniformly and orderly distributed at intervals, and the timber piles are fixed in the soil of a river; the permeable artificial T-shaped dam is characterized in that a layer of geotechnical cloth is arranged at the periphery of the timber piles, a coarse gravel layer and a fine gravel layer are arranged in the region surrounded by the timber piles in sequence from the bottom to top, a broken stone layer is arranged above the fine gravel layer, and aquatic plant is planted in the broken stone layer; a plurality of cultivation barrels are uniformly fixed at two sides of the fine gravel layer, and artificial seaweeds are planted in the cultivation barrels; a bottom end inlet is formed in the lower part of the geotechnical cloth in the inflow side, and an upper outlet is formed in the upper part of the geotechnical cloth in the side back on to the inflow direction. According to the permeable artificial T-shaped dam for planting artificial seaweeds and the construction method thereof, water flows from low to high in the T-shaped dam, this is good for the full contact between the water body and plant roots, the river purification ability is increased, the structure is simple and reasonable, the construction cost is low, the river purification ability is strong, the beneficial effect is obvious, and the application and popularization are facilitated.

Description

technical field [0001] The present invention relates to a T-shaped dam and its construction method, more specifically, to a permeable artificial T-shaped dam planted with artificial aquatic plants and its construction method. Background technique [0002] The artificial T-shaped dam in the existing river is generally an earth pile or cement pile structure, which is built on one side of the river, and has the effect of retaining part of the water conservancy in the river. Because the entire T-shaped dam is impermeable, the water area behind the T-shaped dam is in a static state, forming a stagnant water area. The long-term stagnation of the water area is not conducive to exerting the self-purification ability of the river. If there is a permeable T-shaped dam, it can not only meet the needs of tourists to step along the T-shaped dam, but also avoid the phenomenon of "dead water" in the river due to the interception of the T-shaped dam, which can effectively enhance the purifi...

Problems solved by technology

[0003] Due to the extensive use of chemical fertilizers in farmland around the river, there is eutrophication in the existing river. If the eutrophicated river is not treated in time, it will easily lead to the breeding and reproduction of aquatic algae, and the growth of algae will deplete the oxygen in the water. amount, resulting in the death and extinction of aquatic animals, further exacerbating the deterioration of river water quality and ecological damage
