The production requirement of the model and size of the drainage channel is the size standard, and if the overall components are smooth and smooth, there is no ponding position under the channel, which meets the production requirements. When excavating the soil, it should be tested and tested, and the construction can only be carried out after it is qualified. This is to avoid water infiltration into the bottom of the subgrade, and the subgrade drainage should be in accordance with the design requirements Install according to the drawing. Subgrade is very important for road stability, and it is the foundation of road traffic safety. The main problem of damaging subgrade structure is water. In summer, if there is a lot of precipitation, the subgrade will be in a long-term immersion, and it will become soft. Therefore, the drainage tank is used to let the water in it drain out of the road boundary in time to effectively protect the stability of the subgrade. The drainage channel mold is an important tool to make the cement form and solidify. Therefore, its hardness is an important feature of the mold products, and it has the advantage of making cement prefabricated parts. It can maintain stable and non deformation when vibrating. Therefore, this large mold product will thicken the thickness of rib plate and panel, which can adapt to the huge friction and stress generated in the production process It's more reliable.
The main purpose of using drainage facilities in traffic construction is to avoid the erosion of water during construction, which makes the subgrade loose. The size of U-shaped groove mold is standard U-shaped groove mold positioning can produce U-shaped groove for installation, and we should pay attention to reinforcement and protection measures during excavation, which is to avoid the soil loosening of the base. If the construction is carried out at night, there should be a reasonable process to prevent over excavation or wrong excavation. A layer of permeable cushion should be placed under the subgrade to prevent water leakage The phenomenon of dew. The construction process of U-groove mold can not be easily modified, because every detail treatment will affect the installation and use quality of U-groove. The structural form, shape and size and materials of this steel mold are made according to the drawings provided by customers. Its overall design should meet the needs of construction, and the type of concrete used in this process is also There are regulations. There are strict requirements for the ratio of cement and water cement inside, so that the quality of the concrete U-shaped groove can meet the requirements. After the production is completed, it must be tested and tested before it can be used.
