Problems solved by technology

[0008] Doing this kind of test requires special test conditions, professional personnel, long time and high cost, which limits the root puncture resistance test. In my country, only one place in Beijing conducts the root puncture resistance test, which limits the detection of root puncture resistance waterproof materials. , is not conducive to the development of national roof greening work

Embodiment 1

[0030] Embodiment 1: a kind of device and method for measuring the root puncture resistance of asphalt waterproof material, this device is the root puncture resistance test tank, see Figure 1 to Figure 5 , the root puncture resistance test groove is divided into two parts, the bottom groove 1 and the upper groove 2. The upper part of the bottom groove 1 and the lower part of the upper groove 2 are respectively provided with protruding edges, and the edges are correspondingly provided with holes for fixing the upper and lower grooves. Several openings 8, the bolts 3 as fasteners pass through the openings 8 to fasten and connect the bottom groove 2 and the upper groove 3 to form a root puncture resistance test groove. Drainage hole 5 is so as to discharge redundant moisture in the planting soil of last groove 1 at any time, and the inboard of drainage hole 5 is provided with the folder groove 6 of polyester nonwoven fabric for fixing filtration and polyester nonwoven fabric 7 fo...

Embodiment 2

[0032] Embodiment 2: A kind of device and method for measuring the resistance to root puncture of bituminous waterproof materials, with broad beans 10 (also known as soybeans, Buddha beans, Sichuan beans, Japanese beans, Luohan beans, annual or more annual herbs) produced in the south of my country Plants, which are planted in all provinces in southern China) as the plant seeds used in the determination method, the determination method is as follows:

[0033] First, prepare two root puncture-resistant test tanks for parallel tests, place the bottom tank planting soil 11 in the bottom tank 1 and fill it up so that the bottom tank planting soil 11 is flush with the upper edge of the bottom tank 1;

[0034] Cut out a 300×250mm waterproof material sample 9 to be tested, place the waterproof material sample 9 on the bottom tank planting soil 11, and align the edge of the waterproof material sample 9 to be tested with the bottom tank 1 edge;

[0035] Place the upper groove 2 on the w...

Abstract

The invention relates to a device and method for testing root penetration resistance of asphalt waterproof material. The device is composed of two parts, namely a bottom trough and an upper trough, which are fixedly connected to form a whole, wherein a water drainage hole is arranged below the side face of the upper trough; a sandwich trough and filter cloth are arranged at the inner side of the water drainage hole; and a water drainage hole is arranged at the center of the bottom of the lower trough. The testing method comprises the following steps: selecting broad beans grown in the south of China as the plant seeds used in the testing method, and placing planting soil in the bottom trough and enabling the planting soil to be level with the upper edge of the bottom trough; placing a waterproof material test specimen on the planting soil in the bottom trough, evenly spreading and burying the broad bean seeds in the planting soil in the upper trough, and covering the seeds with the planting soil; determining the performance of root penetration resistance of the asphalt waterproof material according to growing situation of the seed root hair in the test specimen on both sides of the waterproof material test specimen. The device provided by the invention has scientific and reasonable structure, and is convenient for operation. The method for testing the performance of root penetration resistance of the asphalt waterproof material by using the device is simple, time-saving, labor-saving and cost-saving, and is convenient for generalization and application.

Description

technical field [0001] The invention relates to a device and a method for measuring the root puncture resistance of waterproof materials, in particular to a device and a method for measuring the root puncture resistance of asphalt waterproof materials. Background technique [0002] The planted roof system refers to the planted surface on the roof of the roof garden and the underground garage. Because of its advantages of beautifying the city, purifying the air, adjusting the ambient temperature, reducing the urban heat island effect, and making full use of rainwater irrigation, it is highly praised by people and is called "one of the ten effective measures to improve the global warming". [0003] Planting roofs has a long history of more than 4,000 years, from the castle temple towers in the lower reaches of the Euphrates River in ancient times (now Iraq) to the hanging gardens in Babylon; The historical footprint of the planted roof development. After the 1990s, Beijing, ...
