In the process of rapid social and economic development in China, the development level of road and bridge construction projects is getting higher and higher. Highway bridge is not only the construction of transportation infrastructure in China, but also the main driving force to promote the rapid development of China's economy. In the process of road and bridge operation, strengthening the research of bridge surface waterproof operation technology can improve the quality of bridge surface operation and prolong the service life of bridge. This paper discusses the technical requirements of bridge waterproofing engineering, the corresponding waterproof materials and the technical points of bridge surface waterproofing engineering, and formulates a scientific and effective quality management strategy of bridge surface waterproofing engineering, which ensures the effect of bridge waterproofing engineering and improves the level of bridge engineering in China. The bridge protection tool factory below talk about the bridge surface waterproof operation technology.

In bridge operations, there may be some holes in the contact surface of the asphalt concrete layer. Affected by rain and snow, rain and snow will enter the gaps of the asphalt concrete layer. Under long-term rain and snow erosion, the stability of the bridge surface and the quality of the bridge surface will be seriously affected. Especially in winter when the temperature is low, if there is a lot of water inside the bridge between the bridge surface plates, the concrete may freeze. In this case, if the vehicle is working under vertical pressure, the bridge may generate greater internal stress. The water transfer between the surface of the bridge will increase the hydrodynamic pressure, which will easily lead to serious cracks in the bridge, which will have a significant impact on the safety of the bridge. Therefore, the bridge protection tool factory believes that it is necessary to pay attention to the effective application of bridge waterproof operation technology in the bridge operation process. In the process of designing the bridge surface waterproofing system, a spacer should be added between the waterproof layer and the asphalt cement concrete to eliminate the role of rain and snow on the bridge surface to the greatest extent, and reduce the damage to the bridge surface caused by moisture erosion, thereby improving the overall operation quality of the bridge project.

1. Overview of bridge surface waterproofing technology in bridge operation

Strengthening the bridge surface waterproofing engineering work in the process of bridge operation can effectively improve the operation quality of the bridge. First, in the process of waterproof design of bridge surface operation, we should pay attention to bridge selection. Before the operation, choose the operation technology with simple operation without affecting the surrounding ecological environment. When selecting raw materials, it is necessary to ensure that the raw materials have a certain degree of cohesion, which can effectively bond cement, concrete, etc., and improve the firmness of the bridge surface and the quality of operations. Secondly, the bridge defense tool factory recommends that when completing the waterproof layer operation, effective protective measures should be used to improve the waterproof performance of the coating, ensure that the coating has strong adhesion, and make the waterproof layer have strong oxidation resistance, temperature changes and Anti-corrosion ability. Improve the overall tolerance of the deck and the waterproof ability of the deck. Third, when working on the bridge surface, it is necessary to start from the overall application function of the bridge surface, improve the waterproof performance of the bridge surface, ensure the bonding performance of the bridge surface, and bond the asphalt concrete pavement and the bridge surface to ensure the quality of the bridge surface.

2. Bridge Surface Waterproof Material Type

In the process of research on deck waterproofing engineering technology in bridge operations, attention should be paid to the scientific selection of waterproof materials. Commonly used waterproof materials for bridge surface operations include: 1. epoxy latex waterproof coating is a relatively common waterproof material. The bridge defense tool factory believes that it is generally composed of neoprene latex and epoxy resin emulsion. Compared with other waterproof materials, the price of epoxy latex waterproof coating is relatively low and can be effectively integrated with cement concrete. However, in the application process of epoxy latex waterproof material, the affinity with asphalt mixture is relatively low, and serious shedding phenomenon may occur. Second, cationic neoprene asphalt waterproof material. This kind of waterproof material is also common in the process of bridge waterproof operation, which is composed of neoprene latex, petroleum asphalt and other substances. Cationic neoprene latex can adapt to the temperature change of the outside world, and the dryness requirement of the bridge surface base is relatively low, so this waterproof material is widely used in various bridge operations.

When carrying out bridge surface operations, rainwater is an important factor affecting the quality of bridge surface operations. The bridge protection tool factory believes that the erosion effect of rainwater may be intensified, especially during the rainy season. Therefore, the bridge protection tool factory believes that when the bridge surface waterproofing operation is carried out in the material operation process, the double chloroprene rubber latex material can be used to adapt to the change of external temperature in time to make up for the waterproof layer operation problem. However, the bridge defense tool factory believes that the waterproof material has low resistance to high temperature in the application process, weak adhesion ability, and can extend the operation time during operation. Third, polyurethane elastic waterproof material. When you apply this material, you can mix it with other materials. Different mixing methods can achieve curing and improve the elasticity of the waterproof material. This waterproof material also has a high temperature effect, but in the application process, the quality requirements of the bridge surface are relatively high, and separation may occur. Maintenance costs are also high when the bridge surface is repaired at a later stage. Fourth, PC rubber waterproof roll is a new waterproof material, which is not wide in our country. The material has strong adhesion of waterproof layer in the application process, can effectively integrate with concrete and asphalt mixture, and has strong low temperature resistance. Fifth, the main composition of polymer asphalt waterproof material is resin modifier, composite ion emulsified asphalt and rubber. The main application advantages of this waterproof material are fixed structure, high temperature and low temperature resistance. The bridge defense tool factory believes that blisters, sliding problems, indirectness, and continuity are relatively weak during use. In the application process of this waterproof material, the operation efficiency can be improved, the operation progress can be guaranteed, the operation mode is relatively simple, and the application cost is relatively low. Therefore, waterproof materials are widely used in bridge surface waterproof engineering.

bridge surface waterproofing operation technology in bridge operation before carrying out bridge surface operation, sufficient preparations should be made to ensure the smooth progress of subsequent bridge surface waterproofing works. First, the overall condition of the bridge surface should be analyzed and investigated before operation. When inspecting and studying the surface state of the bridge, it is necessary to accurately determine whether the bridge surface has corresponding operating standards. According to the actual situation of the bridge surface, to develop a scientific and effective bridge surface waterproof engineering program. Second, it is necessary to carry out sufficient preparation of working materials, and determine the quality and quantity of waterproof materials according to the technical requirements of the bridge surface waterproof engineering. Third, the bridge surface should be thoroughly cleaned before the operation, and it is forbidden to pile up construction waste on the bridge surface to ensure that the bridge surface is clean and clean, and to ensure the smooth progress of later operations.
