Embodiment 1

[0047] 1) Set up an inspection well (2) with a width of 20 cm along the roof edge, and set a drain outlet (1) at the lower part of the contact surface between the inspection well and the roof, and set a spare drain at the upper and lower parts of the contact surface between the inspection well and the aquifer. Water port (3-1) and overflow port (3-2);

[0048] 2) Cleaning the roof, laying a layer of SBS modified asphalt root puncture-resistant waterproof membrane with a thickness of 5mm on its surface as the waterproof root layer (4), and performing a closed water test;

[0049] 3) Lay a protective layer with a thickness of 1mm on the surface of the waterproof root layer (5) HDPE anti-seepage film, and the lap width of the HDPE anti-seepage film is 10cm;

[0050] 4) On-site mixing of lightweight aggregate permeable concrete, first mix cement and pumice evenly according to the proportion, then add water, a special reinforcing agent for permeable concrete, and a water-retaining ...

Embodiment 2

[0058] Omit the same part as in Example 1, the difference is that the thickness of the lightweight aggregate permeable concrete water storage layer is 10cm, and the specific ratio is as follows:

[0059]

[0060]

[0061] Among them, the weight ratio components of the special reinforcing agent for permeable concrete are as follows: 15.8% deionized water; 80% Japanese Showa AD-10 emulsion; 2% Kaiyuan chemical powder polyvinyl alcohol 2488; 1% Sika Polycarboxylate superplasticizer 325C; 0.2% of Dow Corning Dimethicone OFX-0193.

Embodiment 3

[0063] Omit the same part as in Example 1, the difference is that the specific proportion of lightweight aggregate permeable concrete is as follows:

Abstract

The invention provides a roof greening structure and a greening method. The roof greening structure comprises a main structure and an auxiliary structure, wherein the main structure comprises a water-proof root-blocking layer, a protection layer, a light-weight aggregate pervious concrete water storage layer, a filter layer, a light nutrient soil layer and a vegetation layer which are paved on the main structure in sequence; the auxiliary structure comprises a water drainage opening, an inspection well, a spare drain opening and an overflow opening; the material, namely light-weight aggregate pervious concrete, of the light-weight aggregate pervious concrete water storage layer is prepared from the following materials by weight: 50 to 80 parts of pumice, 15 to 45 parts of cement, 5 to 15 parts of water, 0.5 to 1.5 parts of a special strengthening agent for pervious concrete, and 0.1 to 0.5 part of a water-retaining agent. The void ratio of the light-weight aggregate pervious concrete water storage layer is equal to or larger than 20 %, can store rainwater of concentrated rainfall, and has the functions of flood detention, storage regulation, flood peak reduction, and initial rainwater purification in a regional scale; due to the large void structure, plant roots can penetrate easily, so that the roof greening structure and the greening method are suitable for planting low shrubs and dwarf trees, and have a good root fixing effect.

Description

technical field [0001] The invention belongs to the technical field of roof greening, in particular to a roof greening structure and a greening method. Background technique [0002] Roof greening can be understood as a general term for gardening and planting trees and flowers on the roofs, terraces, roofs, balconies or large artificial mountains of various buildings, structures, city enclosures, bridges (overpasses). In recent years, with the continuous development of cities and the acceleration of urbanization, urban land resources have shown the trend of "every inch of land is expensive", and the land resources specially used for urban greening construction are very limited. It is neither economical nor realistic to expand the area of ​​urban green space. As the "fifth facade" of urban buildings, roof greening is a comprehensive modern technology that integrates architectural art and greening art. It can perfectly combine and fully utilize the spatial potential of urban b...
