Embodiment 1

[0032] An ecological concrete slope protection construction method based on a vertical drainage channel, comprising the following steps:

[0033] The first step, undisturbed soil slope 1 trimming and slope cutting

[0034] The sundries on the surface of the original soil slope 1 are removed, and the original soil slope 1 is trimmed, slope cut, and compacted according to the slope ratio and structural requirements for forming slope protection.

[0035] The second step is to set up the plastic drainage board 9

[0036] Before laying the plastic drainage board 9, use GPS to measure and release the construction sidelines of each area, arrange the points of the plastic drainage board in a square or plum blossom shape, and the distance between adjacent plastic drainage board points is 1m, and use the plugging machine to punch the plastic drainage board 9 Set to design depth, the board head of plastic drainage board 9 exposes 30cm on the ground.

[0037] The third step, pouring eco...

Embodiment 2

[0048] The difference between this embodiment and Example 1 is that the matrix balls are filled into the holes 10 of each layer of ecological greening concrete, and the matrix balls are spheroids made of soil, slow-release fertilizer, organic matter, and water-retaining materials. 5mm to 10mm. The matrix ball is composed of the following components in mass percentage: 90% soil, 4% slow-release fertilizer, 3% organic matter, and 3% water-retaining material. The preparation process of the matrix ball is as follows: mix the soil, slow-release fertilizer, organic matter, and water-retaining materials according to the above ratio and stir evenly, then add an appropriate amount of water, mechanically make the stirred mixture into a spherical shape, and then screen out the design after drying. particle size matrix balls. Among them, the soil is ordinary planting soil, the slow-release fertilizer is magnesium ammonium phosphate, the organic matter is flour (the flour can be wheat flo...

Abstract

The invention provides a construction method of an ecological concrete protected slope based on a vertical drainage channel. The construction method comprises the following steps: first, an original state soil side slope is trimmed and cut; 2, a set of vertically-arranged drainage boards is driven in the trimmed soil side slope; 3, ecological greening concrete is poured on a to-be-treated slope surface; 4, nutrient soil and planting soil are laid on the ecological greening concrete in sequence; 5, appropriate grass seeds are selected to be sown on the protected slope, or turf is laid on the protected slope; and 6, the planted turf is maintained. An ecological concrete slope protection technology cooperates with landscape greening, the problem of insufficient greening of a traditional protected slope is avoided, it is guaranteed that plants are easier to root in a soil body of the protected slope while the safe stability of the protected slope is met, and thus the ecological greening protected slope is constructed.

Description

technical field [0001] The invention relates to an ecological concrete slope protection construction method based on a vertical drainage channel, and belongs to the technical field of ecological slope protection. Background technique [0002] In the practice of long-term struggle with rivers, human beings have explored some river slope protection models that adapt to local natural conditions. Traditional river slope protection mainly includes mortar or dry block stone slope protection, cast-in-place concrete slope protection, prefabricated concrete block slope protection and other methods. The cost of these slope protection projects is relatively high, and the underwater construction and maintenance work is relatively difficult. These structural forms of slope protection have played a certain role in maintaining the structural stability of the bank slope, preventing soil erosion, and flood control and drainage. However, to varying degrees, they have negative impacts on the...
