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] Such as figure 1 As shown, an ecological waterway barge includes a barge body 1, which is located at the slopes on the left and right sides of the channel. The revetment body 1 includes an immersion separation section 2, a green infiltration section 3, and a plant planting section 4 formed one by one from the corner of the embankment to the top of the embankment; under normal water levels, the immersion separation section 2 is generally immersed below the water surface of the channel. To infiltrate the channel water body and block the penetration of salt and alkali components in the channel water body, the green infiltration section 3 and the plant planting section 4 are located above the water flow surface of the channel, and both play the role of infiltrating the rainfall water body and decorating the channel revetment. In coastal or inland rivers with high saline-alkali conditions, it is difficult for the saline-alkali components in the channel water to penetrate into ...

Embodiment 2

[0051] Such as Figure 5 As shown, an ecological waterway revetment construction method includes the following steps:

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

[0053] S2. Arrange the planting layer 411, the filter layer 412, the drainage layer 413, the moisturizing layer 414, the root layer 415, and the anti-leakage layer 416 from top to bottom in the pier body 1, and water storage in the pier body 1 Pool 61, and excavate a water storage pipeline 62 connecting the storage and drainage layer 413 and the reservoir 61.

[0054] S3. Arrange the straw permeable layer 222, the partition wall 223, the distiller's grain permeable layer 221 and the inner support cage 24 at the bank corner of the barge body 1 in turn toward the center of the channel, and pour green concrete outside the inner support cage 24 Formed concrete surface layer 23; prefabricated...

Abstract

The invention discloses an ecological channel revetment and a construction method thereof, and relates to the technical field of channel revetment construction. A revetment body is included and comprises an immersion partition section, a greening permeation section and a plant planting section. The immersion partition section comprises an embankment protection slope surface and a salt and alkali permeation preventing layer. The plant planting section comprises surface-layer salt and alkali resisting plants and a soil layer interior water storage layer. The greening permeation section comprisesa concrete constructed slope surface and surface-layer greening plants. The ecological channel revetment is composed of the revetment body, the immersion partition section, the greening permeation section and the plant planting section. When salt and alkali are prevented from eroding the revetment body, water permeation exchange of the revetment body and a surrounding water body is achieved, thenthe purpose of planting the surface-layer greening plants and the surface-layer salt and alkali resisting plants is achieved, the purposes of water storage slope fixing and salt and alkali erosion preventing are achieved, and accordingly the purposes of improving the safety of the channel revetment structure under the high salt and alkali environment condition at the coastal position or the inland river and guaranteeing ship navigation safety are achieved.

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] Navigation channel refers to the navigation channel for ships prescribed or set up (including construction) in waters such as rivers, lakes, and seas. According to the location, it can be divided into two types: inland waterway and coastal waterway. Among them, coastal waterway refers to the waterway that is located near the coastline and has a certain boundary for ships to navigate. Barge refers to a structure used to prevent riverbanks from collapsing or scouring. Channel barge plays a very important role in improving the safety of ship navigation. [0003] The existing Chinese patent with the authorized announcement number CN104005370B discloses a hollow block ecological protection surface reinforced soil lightweight revetment retaining wall and its construction ...
