Problems solved by technology
A biofilm will grow on the surface of the stone, which can purify the river water to a certain extent, but its effect is limited by factors such as the material of the stone, the shape of the surface, and the state of the water flow.

Embodiment Construction
[0013] As shown in Figure 1, pebbles with a diameter of 1 to 5 cm and an appropriate amount of cementitious material are cemented into a porous block 3 with a diameter of 10 to 20 cm, and filled into a plastic-sprayed wire mesh cage 6 to form a gabion. A blind pipe with a diameter of 10-20 cm around the hole is set as the water diversion and water pipeline 4, and a natural fiber mat 5 is fixed on the upper part of the gabion to plant aquatic plants 1, and the root system 2 of the plant will be inserted into the gabion.

The present invention relates to a kind of stone cage structure for protecting bank and the water purifying method therewith. Sewage purifying underflow wetland technology is introduced to the stone cage structure to make the stone cage structure become novel bank protecting structure with powerful water purifying function. The present invention features that crushed stones are cemented into large porous block filled into netted cage to form stone cage, water flow pipes are introduced into the cage, and natural fiber cushion is fixed on or inside the stone cage for planting aquatic plant. The novel bank protecting water purifying stone cage structure combines the stability of stone cage structure, water purifying performance of cemented crushed stones and the protecting performance and water purifying performance of aquatic plant and has landscape, ecological and hydrophilic functions.
Description
technical field [0001] The invention relates to a gabion structure for revetment, in particular to a novel gabion revetment structure with strong water purification function utilizing the principle of subsurface flow wetland to purify water, and a water purification method using the structure. Background technique [0002] In order to prevent the bank slope of the river from being washed by the river, embankments are generally built on both sides of the river. The general gabion revetment is to fill the stones into the mesh cage to form a gabion, and then combine the gabion to form a revetment structure. A biofilm will grow on the surface of the stone, which can purify the river water to a certain extent, but its effect is limited by factors such as the material of the stone, surface shape, and water flow. The invention introduces the underflow wetland technology used for purifying sewage into the gabion structure, so that the gabion structure can be further extended into a...
