Problems solved by technology

However, in coastal or inland rivers with high salinity conditions, water with high salinity content scours and infiltrates into the above-mentioned channel revetment, which will cause the rapid aging of the channel revetment, and even cause the revetment to collapse, seriously affecting the safety of ship navigation There is room for improvement in existing technologies

Embodiment 1

[0040] like figure 1 As shown, an ecological waterway revetment includes a revetment body 1, and the revetment body 1 is located at the left and right sides of the waterway. The revetment body 1 includes an immersion separation section 2, a greening penetration section 3, and a plant planting section 4 formed one by one from the embankment angle to the embankment head; under normal water level conditions, the immersion separation section 2 is generally submerged below the water flow surface of the channel, and the To infiltrate the channel water body and block the penetration of saline-alkali components in the channel water body, while the green infiltration section 3 and plant planting section 4 are located above the water flow surface of the channel, both play the role of infiltrating the rainfall water body and decorating the channel revetment. In coastal or inland river high salinity environment conditions, it is difficult for the saline-alkali components in the channel wa...

Embodiment 2

[0051] like Figure 5 As shown, a construction method for ecological waterway revetment includes the following steps,

[0052] S1. Excavate the revetment body 1 according to the design standards and requirements of the waterway revetment, that is, excavate the revetment body 1 on the slopes on both sides of the waterway.

[0053] S2. Arrange planting layer 411, filter layer 412, storage and drainage layer 413, moisture retention layer 414, root separation layer 415 and anti-leakage layer 416 in the revetment body 1 from top to bottom, and set water storage in the revetment body 1 pool 61, and excavate the water storage pipeline 62 connecting the storage and drainage layer 413 and the water storage tank 61.

[0054]S3. Arrange the straw permeable layer 222, the separation retaining wall 223, the lees permeable layer 221 and the inner support cage 24 at the bank angle of the revetment body 1 toward the center of the channel in sequence, and pour green concrete outside the inner...

Abstract

The invention discloses an ecological waterway revetment and a construction method thereof, and relates to the technical field of waterway revetment construction. Slope and anti-salt-alkali infiltration layer; the planting section includes surface-resistant and saline-alkali-resistant plants and the aquifer in the soil layer, and the greening infiltration section includes concrete construction slopes and surface greening plants. The ecological waterway revetment is composed of the revetment body, the immersion separation section, the green infiltration section and the planting section. While blocking the saline-alkali erosion of the revetment body, it can realize the water seepage exchange between the revetment body and the surrounding water body, so as to realize the planting of surface green plants and The purpose of the surface layer is resistant to saline-alkali plants, so as to achieve the purpose of water storage and slope consolidation and prevention of saline-alkali erosion, and then to improve the safety of the channel revetment structure in coastal or inland rivers with high saline-alkali environment conditions, and to ensure the safety of ship navigation Purpose.

Description

technical field [0001] The invention relates to the technical field of waterway revetment construction, in particular to an ecological waterway revetment and a construction method thereof. Background technique [0002] Waterways refer to the ship navigation passages stipulated or set up (including construction) for ship navigation in rivers, rivers, lakes, seas and other waters. According to the location, it can be divided into two types: inland waterways and coastal waterways. Among them, coastal waterways refer to waterways located near the coastline with certain boundaries for ships to navigate. The revetment refers to the structure used to prevent the river bank from collapsing or scouring, and the channel revetment plays a very important role in improving the safety of ship navigation. [0003] The existing authorized notification number is the Chinese patent of CN104005370B, which discloses a reinforced soil lightweight revetment retaining wall with hollow block ecolo...
