The following introduction to the availability of road armor seam subway warehouses is quite good, and you will be able to have a deeper understanding of this by reading the following article.
Road armor joints refer to the waterproofing, drainage and crack prevention gaps set on asphalt or concrete roads paved on the road surface. A subway warehouse is an underground structure used to store and maintain subway trains. The following will be an in-depth analysis of the design principles and construction methods of the road armor joint subway warehouse.
Design principles: 1. Adapt to the deformation of the pavement: The design of the road armor joint needs to consider the deformation of the pavement to ensure that the gap can bear the deformation and load of the pavement.
2.Waterproof and drainage: Road armor joints need to have good waterproof and drainage performance, which can effectively prevent water from seeping into the road surface, avoid sewage accumulation, and reduce the risk of road damage and slipping.
3.Wear and durability: Road armor joints need to be able to withstand the friction and pressure of vehicle traffic, have strong wear durability, and extend the maintenance cycle.
4.Convenient maintenance and replacement: The convenience of repair and replacement needs to be considered when designing road armor joints, so as to reduce the impact on traffic and waste of costs.
Construction method: 1. Pavement preparation: Before the construction of road armor joints, it is necessary to clean and prepare the pavement to ensure that the pavement is smooth, dry and clean.
2.Gap cutting: According to the design requirements, a gap of a certain width and depth is cut on the road surface, and an electric cutting machine or mechanical cutting machine is generally used for cutting.
3.Gap treatment: To treat the bottom of the gap, you can use high-pressure air to blow away the debris and dust in the gap, and clean the moisture on the road surface. The gap is then filled with a primer to fill in.
4.Waterproof layer construction: After the primer is filled, the waterproof layer is constructed, and polymer modified asphalt or other suitable materials are generally selected for construction to ensure that the joints have waterproof performance.
5.Armor construction: After the completion of the waterproof layer, the armor construction is carried out, and flexible or semi-flexible armor materials can generally be laid, such as rubber, metal or plastic armor materials.
6.Edge treatment: The edges on both sides of the gap are treated, and the edge material can generally be fixed with adhesive or adhesive tape to ensure that the gap is stable.
7.Follow-up maintenance: After the construction of the road armor joint is completed, regular maintenance and inspection work needs to be carried out, and the damaged armor materials should be repaired and replaced in time to maintain the good use of the road.
The design principles of the road armor joint subway warehouse include adapting to pavement deformation, waterproof drainage, wear resistance and durability and convenient maintenance and replacement, and the construction methods mainly include pavement preparation, gap cutting, gap treatment, waterproof layer construction, armor construction, edge treatment and follow-up maintenance. These principles and methods can effectively ensure the use effect and safety of road armor joints in subway warehouses.
