Embodiment 1

[0046] Such as figure 1 As shown, an anti-scour water storage type roof greening structure includes a waterproof layer 2 laid on the upper surface of the roof layer 1, and the waterproof layer 2 even has a drainage layer 3, a filter layer 4, a water-retaining layer 5, and a planting layer from bottom to top. layer 6 and vegetation layer 7;

[0047] The waterproof layer 2 adopts oil-based chemical coatings such as impermeable membrane materials or polyurethane, with a thickness of 0.1-0.3mm

[0048] Drainage layer 3 is a plastic water-retaining drainage board, including a flat body, on which there are evenly distributed cylindrical hollow sinkers with an inner diameter of 10-25 mm, protruding from the lower surface of the flat body to form a cylindrical support, and each cylindrical hollow sinker The gap between them forms a drainage channel;

[0049] The filter layer 4 is nylon mesh or non-woven fabric;

[0050] The water-retaining layer 5 is a water-retaining layer made of...

Embodiment 2

[0067] A laying method of the above-mentioned greening structure, the method comprises the following steps:

[0068] Step 1: laying a waterproof layer 2 on the upper surface of the roof layer 1;

[0069] Step 2: laying a drainage layer 3 on the surface of the waterproof layer 2;

[0070] Step 3: laying filter layer 4 on drainage layer 3;

[0071] Step 4: laying a water-retaining layer 5 on the filter layer 4;

[0072] Step 5: Weighing each component for preparing the planting layer substrate;

[0073] Step 6: Planting substrate preparation:

[0074] Step 6-1: Add the graphene in the above parts by weight into the biochar evenly in layers, firstly mix by upper stirring, and then further mix and disperse by lower stirring;

[0075] Step 6-2: After the humus is preliminarily stirred and decomposed, add vinegar grains for further mixing, and at the same time, add cement to the prepared humic acid fertilizer to neutralize its excess free acid, and initially adjust the pH value ...

Abstract

An anti-scouring water storage type roof greening structure comprises a waterproof layer laid on the upper surface of a roof layer, and a drainage layer, a filtering layer, a water retention layer, aplanting layer and a vegetation layer are sequentially arranged on the waterproof layer from bottom to top. The drainage layer is a water retention and drainage plate; the filtering layer is made of nylon gauze or non-woven fabric; and the water retention layer is a water-absorbing cotton strip water retention layer. According to the anti-scouring water storage type roof greening structure, the problems of water and soil loss and environmental pollution can be solved, the structure is stable, construction is easy, and anti-scouring and recyclable rainwater utilization can be achieved on a conventional roof and some special roofs (such as a dome and a slope top).

Description

technical field [0001] The invention relates to the technical field of roof greening, in particular to an anti-scouring water storage type roof greening structure and method. Background technique [0002] In recent years, waterlogging every time it rains has gradually evolved into a chronic disease in large and medium-sized cities in my country. In order to effectively solve the problem of urban water security and promote the harmonious development between man and nature, one of the important strategies of Sustainable Urban Drainage System (SUDS) and Water-Sensitive Urban Design (WSUD) system is to control the source of runoff in order to reduce the peak value of surface runoff and Reduce runoff pollution. [0003] Green roofs compensate for land use, improve air quality, relieve pressure on city sewage systems by conserving stormwater, save energy and beautify ugly gray and black roofs. However, there are many problems in existing roof greening. For example, the greening ...
