Embodiment Construction
[0032] Such as Figure 1 to Figure 4 Shown, be the construction method of a kind of water purification type ecological revetment of the present invention, comprise the steps:
[0033] a. Foundation pit excavation
[0034] 1) Survey and clean up the construction site, then carry out lofting and positioning according to the laying route of the ecological block 1, then use an excavator to excavate the earthwork, and then use the excavator wheel to compact and flatten the slope surface to ensure that the excavation earthwork The flatness of the surface facilitates the installation and fixation of the subsequent ecological block 1;
[0035] 2) Evenly lay a layer of 5cm gravel cushion on the bottom of the excavated earth, and then lay a layer of geotextile on the top of the gravel cushion, then lay a geomembrane on top of the geotextile, and then lay on top of the geomembrane. Lay a layer of geotextiles, and finally backfill the soil above the top layer of geotextiles, and compact...

The invention discloses a construction method of a water purification type ecological protection bank. The construction method of the water purification type ecological protection bank comprises the following steps of a, opening a foundation pit; b, dividing regions; and c, building the ecological protection bank. According to the construction method of the water purification type ecological protection bank provided by the invention, through designing a fixed support and an installation plate, the top part of the ecological protection bank can be further installed and fixed, so that the structural strength and the structural stability of the ecological protection bank are improved, and the ecological protection bank can resist the impact force of a water flow; meanwhile, when bottom-layerecological building blocks are paved, through designing reinforced gear blocks, not only can the structural strength of the bottom-layer ecological building blocks be ensured, but also the contact strength between the bottom-layer ecological building blocks and soil can be improved, so that the ecological protection bank is not easy to deform; meanwhile, each two adjacent ecological building blocks can be spliced and further connected and fixed through fixed screws, so that the connecting strength between the adjacent ecological building blocks is effectively ensured; and an auxiliary plantinghole is formed between each two adjacent ecological building blocks and is matched with ecological planting holes of the ecological building blocks, so that a greening area of the ecological protection bank is enlarged.
Description
technical field [0001] The invention relates to a construction method of a water-purifying type ecological revetment. Background technique [0002] Ecological revetment refers to a river slope protection form that can not only prevent river bank collapse, but also allow river water and soil to infiltrate each other, enhance the self-purification ability of the river, and have a certain natural landscape effect. Ecological bank protection refers to a form of river slope protection that uses plants or a combination of plants and civil engineering to protect the river slope. The ecological revetment integrates flood control effect, ecological effect, landscape effect and self-purification effect. It is not only a great progress in revetment construction, but also will become the mainstream of revetment construction in the future. Ecological revetment refers to a river slope protection form that can not only prevent river bank collapse, but also allow river water and soil to in...
