Through the independent pull - out tests of the transverse and longitudinal ribs of the indoor geogrid, the reinforcement mechanisms of the transverse and longitudinal ribs of the geogrid were studied respectively under different normal loads and pull - out speeds. The results show that: the frictional resistance generated by the longitudinal ribs of the geogrid increases rapidly in the initial stage of pull - out, and shows a linear growth trend with the increase of effective stress. The pull - out rate has little effect on it; the passive resistance generated by the transverse ribs of the geogrid increases relatively slowly. A certain relative displacement between the geogrid and soil is required before reaching the peak value. And with the increase of effective stress and pull - out rate, the passive resistance changes significantly, and its failure mode gradually changes from punching shear failure to conventional shear failure.

1. The heat sink of the LED floodlight is made of fin - shaped pure aluminum sheet, which has good heat transfer and conduction effects. It is manufactured with the buckle FIN process and technical design.
2. The contact area between the aluminum substrate and the heat sink of the LED floodlight is increased and they are in close contact without gaps, which reduces the air thermal resistance and accelerates the heat conduction speed of the aluminum substrate.
3. Each fin of the LED floodlight has air holes, and the fins are connected to form an annular air convection channel, so that the high - temperature heat inside the lamp can be exported with air convection or heat sinking.
4. The power supply of the LED floodlight is placed in an insulated and flame - retardant annular power supply box, which meets the safety regulations and ensures safe use. There are air convection holes at the top and bottom, so that the heat generated by the power supply can be dissipated into the air through air convection, reducing the internal temperature of the power supply, prolonging the service life of the power supply, and ensuring the service time of the lamp.
5. The structure of the LED floodlight body is light in weight, only 60% - 70% of the weight of the turned aluminum. There is no need to fill the power supply box with thermal conductive silica gel, which not only reduces the production and maintenance costs of the enterprise but also reduces the transportation cost of the enterprise.
5. The structural parts of the heat sink of the LED floodlight have applied for multiple technical protections
7. Suitable for: Panoramic lighting of internal and external walls in lighting projects, commercial venues, airports, subways, elevated overpasses, billboards, stadiums, architectural landmarks, etc.
- The LED single - walled stadium lights, 50 - watt LED floodlights, and 100W LED industrial and mining lights use American CREE lamp beads, which feature high thermal conductivity, low light decay, pure light color, and no double - image;
- The LED single - walled stadium lights, 50 - watt LED floodlights, and 100W LED industrial and mining lights adopt an integrated design of heat dissipation and lamp housing, which can effectively conduct and diffuse heat, thereby reducing the temperature inside the lamp and ensuring a service life of 50,000 hours for the LED light source. Calculated by lighting for 11 - 12 hours a day, the LED industrial and mining lights do not need to be replaced within 12 years.
- The surfaces of the LED single - walled stadium lights, 50 - watt LED floodlights, and 100W LED industrial and mining lights are treated with anodic oxidation for anti - corrosion, with a compact and beautiful structure. They have good anti - corrosion, waterproof, and dust - proof performance;
- The LED single - walled stadium lights, 50 - watt LED floodlights, and 100W LED industrial and mining lights have obvious energy - saving effects. They use high - power LED light sources equipped with Taiwan Mean Well power supplies, and can save over 60% of energy compared with sodium lamps;
- The LED single - walled stadium lights, 50 - watt LED floodlights, and 100W LED industrial and mining lights are environmentally friendly, containing no polluting elements such as lead and mercury, and causing no pollution to the environment.
- The LED single - walled stadium lights, 50 - watt LED floodlights, and 100W LED industrial and mining lights have good color rendering, presenting the real colors of objects more vividly. There are various light colors to choose from, which can meet the needs of different environments. They can avoid the depressive mood caused by the too - high or too - low color temperature of traditional lamps, making the eyes feel more comfortable and improving the work efficiency of workers.
- The LED single - walled stadium lights, 50 - watt LED floodlights, and 100W LED industrial and mining lights use Mean Well constant - current and constant - voltage power supplies, with a wide applicable voltage range (AC85V - 265V). They overcome the power grid, noise pollution, and unstable lighting caused by ballasts, and avoid eye irritation and fatigue during work.
- The fin - type LED floodlights have good decorative effects. They adopt surface treatment technology, with multiple color options for the appearance. They are easy to install and disassemble, and are very applicable.
The performance of the interfacial transition zone of equal - strength concrete was studied by combining backscattered electron image analysis with nano - indentation technology. The results show that mineral admixtures improve the performance of the interfacial transition zone of equal - strength concrete to varying degrees, and also increase its non - uniformity. The double - doping of metakaolin and limestone powder can reduce the thickness of the interfacial transition zone of equal - strength concrete, significantly reduce the growth rate of its elastic modulus, but increase the elastic modulus of the matrix, while fly ash only reduces the growth rate of the elastic modulus of the interfacial transition zone of equal - strength concrete.
