Problems solved by technology

[0004] The common type of river revetment can meet the safety needs of flood control and flood control, as well as the hydrophilic landscape and ecological needs of the river bank. However, a single slope or simple buffer steps are difficult to solve the debris or pollutants caused by the rain in the rainy season and flood season. and purification issues

Embodiment 1

[0051] Such as Figure 1-4 As shown, an ecological revetment in a water source protection area includes a primary revetment 10 set below the beach elevation a, a secondary revetment 20 set above the beach elevation a, and a revetment between the primary revetment 10 and the secondary revetment 20 For the ecological sewage interception and grass ditch 30, the slope ratio of the first-level revetment 10 is not greater than 1:5, and the slope ratio of the second-level revetment 20 is 1:5-1:2.5.

[0052] The primary bank revetment 10 includes, from bottom to top, a first foundation 11 at the foot of the bank, a sloped primary revetment 12, a first crest 13 at the beach elevation a, and a lead wire cage 14 below the water level. The top surface of the first top pressing 13 is flush with the elevation a of the beach, and the primary slope protection 12 includes a 100mm thick crushed stone cushion layer 44 and a 120mm thick prefabricated block member layer 45 which are successively a...

Embodiment 1

[0061] The construction method of the ecological revetment in the water source protection area of ​​embodiment 1 may further comprise the steps:

[0062] Step 1, construction of first-level revetment 10:

[0063] S1. Groove the first foundation 11 at the water level line during the construction period. The strength grade of the first foundation 11 is not less than 7.5MPa, and the deformation joints are arranged at intervals according to the design regulations. After the strength grade meets the requirements, place the underwater lead wire cage 14. The lead wire cage 14 is laid along the riverbed from the position of the first foundation 11 to the elevation b at the bottom of the riverbed;

[0064] S2. Construct the first topping 13 at the elevation a of the beach, and set deformation joints according to the interval specified in the design, and slope from the first topping 13 along the edge of the beach according to the designed slope rate to obtain the water-facing slope;

Abstract

The invention relates to the field of water source protection area revetment construction, in particular to ecological revetment of a water source protection area and a construction method thereof. The ecological revetment comprises a first-level revetment arranged below the elevation of the bottomland, a second-level revetment arranged above the elevation of the bottomland and an ecological pollutant intercepting grass planting ditch arranged between the first-level revetment and the second-level revetment, and the ecological pollutant intercepting grass planting ditch is in a U-shaped groove shape and is arranged on the side, close to the first-level revetment, of the second foundation. Compared with other reinforcing methods, the ecological revetment has the advantages of being short in construction time, large in reinforcing depth, good in reinforcing quality, remarkable in economic benefit and the like, and particularly, the ecological pollution intercepting grass planting ditch is specially arranged, so that the functional effects of soil retaining, reverse filtering and drainage of the revetment are improved, and the ecologicalization and humanistic landscape of the revetment are improved.

Description

technical field [0001] The invention relates to the field of revetment construction in water source protection areas, in particular to an ecological revetment in water source protection areas and a construction method thereof. Background technique [0002] In order to make the embankment slope protection of the water source protection area not only maintain water and soil, strengthen the embankment, but also purify water quality and maintain biodiversity, and at the same time reduce the impact of non-point source pollution on the water body on both sides of the river, and realize the goal of ecological water source protection area, the river ecological revetment project Technology puts forward higher requirements for soil retaining, reverse filtration, drainage, ecology, and humanistic landscape design. [0003] In order to effectively prevent soil erosion and ensure the safety of embankments, the key to the construction of ecological river revetments is the disposal of rive...
