Problems solved by technology
The existing ecological block structure is simple and easy to construct, but the overall structural strength of the ecological revetment composed of ecological block groups is average, and the ability to resist water impact is average, resulting in higher maintenance costs in the later period

Embodiment Construction
[0032] Such as Figure 1 to Figure 4 As shown, the construction method of a water-purifying ecological bank protection according to the present invention includes the following steps:
[0033] a. Excavation of foundation pit
[0034] 1) Survey and clean up the construction site, then set out and position according to the laying route of ecological block 1, then use excavators to excavate the earth, and then use excavator wheels to compact and flatten the slope surface to ensure the excavation of the earth The flatness of the surface facilitates the subsequent installation and fixation of the ecological block 1;
[0035] 2) Pave a layer of 5cm gravel cushion evenly on the bottom of the excavated earthwork, and then lay a layer of geotextile on top of the gravel cushion, and then lay the geomembrane on top of the geotextile, and then place it on top of the geomembrane. Lay a layer of geotextile, and finally backfill the soil above the uppermost geotextile, compact and flatten it. Whe...

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 for water purification type ecological bank protection. Background technique [0002] Ecological bank protection refers to a form of river slope protection that can not only prevent river bank collapse, but also allows river water and soil to penetrate 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 slope of the river. Ecological revetment integrates flood control, ecological, landscape and self-purification effects. It is not only a great progress in the construction of revetment projects, but will also become the mainstream of the construction of revetment projects in the future. Ecological bank protection refers to a form of river slope protection that can not only prevent river bank collapse, but a...
