Landscape drainage ditches not only meet the basic functions of drainage ditches, but are also an important landscape element. The design of landscape drainage ditch covers is to landscape the drainage ditch, focusing on the joint design of functionality and artistry, and realizing the unity of "functionality" and "artism". Through its own form, color, material texture selection and landscape design combination, it shows people the characteristics of its landscape and expresses certain emotions. Through landscape design, the meaning of life originally given by inorganic life forms such as bricks, concrete, and metals can also reflect certain social, regional, folk and other cultural connotations, focusing on symbiosis with nature and integration with landscape.
The specific content of landscape drainage ditch design includes the reasonable arrangement of the position of each ditch, the selection of suitable landscape drainage ditch types, the determination of the ditch top elevation and ditch bottom elevation of the starting point and end point of each ditch, as well as the length and slope of the entire ditch, and finally the configuration of the rainwater outlet and other ancillary facilities of the landscape drainage ditch. These contents must be reasonably designed to meet the functional application of advanced technology and new materials under the premise of meeting the overall planning and engineering standards of the drainage system, fully consider the landscape effect of the drainage ditch, so that it can be integrated with the surrounding environment or even beautified, enrich the types of landscape drainage ditches, and give full play to the ecological benefits of landscape drainage ditches.
In different application occasions, the requirements for landscape drainage ditch covers are also different. Generally, different materials are selected according to the bearing requirements and landscape requirements of the landscape drainage ditch. Commonly used landscape drainage ditch covers include stainless steel covers, galvanized steel grating ditch covers, and cast iron ditch covers.
1. Stainless steel ditch cover: Stainless steel ditch cover is a ditch cover made of stainless steel material, which has the characteristics of high strength, light weight, high molding precision, beautiful appearance, and good cleanliness.
The ditch cover currently used at the entrance and exit of a subway line station is a stainless steel ditch cover.
2. Cast iron ditch cover: Cast iron ditch cover is made of cast iron, which has the characteristics of high strength and firmness, but heavy quality, easy to corrode, poor aesthetics, and difficult to clean.
3. Galvanized steel grating ditch cover: Galvanized steel grating ditch cover is a ditch cover welded with Q235 flat steel, and the surface is hot-dip galvanized. Galvanized ditch cover has the characteristics of easy installation, light weight and low price, strong corrosion resistance, strong anti-rust performance, strong pressure resistance and strong bearing capacity.
