Abstract

The invention relates to a self-repairing anti-root-penetrating concrete waterproof structure and a construction method thereof. The self-repairing anti-root-penetrating concrete waterproof structure is characterized by comprising a self-repairing rigid waterproof layer and a root barrier layer. The root barrier layer is formed by coating a root repellent layer on the self-repairing rigid waterproof layer. The self-repairing rigid waterproof layer comprises, by weight, 1 part of cement, 1.2-1.8 parts of sand, 3-4 parts of fine aggregate, 0.37-0.48 part of water and 0.008-0.015 part of cement-based capillary crystalline waterproofing agent. The root barrier layer has a function of root penetrating prevention and is formed by coating 0.3-0.8 kg / m<2> the root repellent layer on the self-repairing rigid waterproof layer. Under synergistic effect of the self-repairing rigid waterproof layer and the root barrier layer, the self-repairing anti-root-penetrating concrete waterproof structure is capable of effectively preventing penetrating of plant roots, leakage of a green plant roof is avoided, and the service life of the green plant roof is prolonged.

Description

technical field [0001] The invention relates to a waterproof and anti-plant root puncture concrete structure and a construction method for the green planting roof of a building. Background technique [0002] The so-called green planting roof refers to a building roof (including roof, roof, balcony, etc.) or an underground building roof that is paved with planting soil to plant plants. Planting green roofs is an effective way to increase urban green coverage, slow down the "heat island effect", reduce air pollution, save energy, prolong the service life of waterproof layers, improve the ecological environment and beautify the urban landscape. But at present in our country, the green planting roof has not been vigorously promoted, and its main reason is that there are still technical difficulties in anti-root puncture and waterproof treatment. When planting plants on the roof, the roof faces more water sources and the environment is more complicated, especially because the ro...
