Embodiment

[0036] Embodiment: Take the ecological management project of Wutong Mountain rocky slope in the east of Yantian Port, Shenzhen as an example.

[0037] Choose 500m on the excavated grade 6 rock mass exposed slope 2 The overall construction is steep, with a slope of 70-75 degrees.

[0038] The composition of the nutrient matrix of biological hexagonal bricks, in terms of each 1m 3 The soil is calculated by adding the following components:

[0039] Sludge biological drying organic compost: 0.62m 3

[0040] Fine loess: 0.2m 3

[0041] Northeast peat: 0.05m 3

[0042] Ordinary Portland cement: 0.1m 3

[0043] Compound fertilizer, PR-3005M water retaining agent, gypsum: 0.03m 3

[0044] The above composition is mixed with 30% water of dry weight, and mechanically pressed into a hexagonal brick with a side length of 12 cm and a thickness of 9.5 cm.

[0045] Plant seeds: Bermudagrass 2g / m 2 , edamame 5g / m 2 , Leucaena 3g / m 2 Construction method:

[0046] 1. Slope trimmin...

Abstract

The invention relates to a biological brick for ecological slope protection of rock slope surface and a preparation method and a construction method thereof. The biological brick for ecological slope protection is a hexagonal brick pressed by specially-prepared base materials, and the surface of the brick is provided with a notch groove and a pit. The biological brick for ecological slope protection consists of two layers, wherein, one layer is a nutrition medium layer, and the other layer is a seed planting layer; the biological brick for ecological slope protection has the characteristics of light mass, air permeability, water and fertilizer reservation, rainwater erosion and soak resistance, rich nutrition and so on, a seed can directly sprout from the surface layer of the biological brick, and a brick body is also ideally suitable for the growth of a plant. The base materials of the nutrition medium layer of the biological brick consists of biological sludge drying organic compost, fine loam, turfy soil, compound fertilizer, water retention agent, cement and pH modifier. The construction method for the biological brick on a rock slope comprises slope trimming, biological hexagonal brick pavement, anchor bolt driving, net suspension, covering and maintenance. The biological brick is provided with the plant seed planting layer, can be quickly molded at one-time construction to restore the vegetation; compared with other rock slope greening methods, the construction method has the characteristics that: the construction method has simple construction and does not need large-scale mechanical equipment, and the construction cost is two thirds of that of the prior guniting slope protection, etc.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, in particular to an ecological slope protection bio-brick for rocky slopes and its preparation and construction methods. technical background [0002] In recent years, due to the acceleration of development and construction and urbanization, the contradiction between urban construction and ecological protection has become increasingly aggravated. In the process of infrastructure construction such as transportation, water conservancy and municipal facilities, a large number of excavated mountains and flats and quarried soil have not only destroyed the topography and native vegetation, but also formed many broken mountain zones with exposed slopes as the main feature. Water and soil conservation and ecological protection, urban landscape and human settlements have all produced extremely adverse effects. If not treated in time, serious environmental problems will occur. [0003] Th...
