(A) of the crack repair techniques Diseases of the structure and reinforcement of roads and bridges Paper Keywords: roads and bridges; structural disease; crack repair; reinforcement enhanced Abstract: article describes the causes of disease as a bridge,buy ghd hair, bridge strengthening processes and several reinforced enhancement techniques, namely the crack repair techniques and reinforcement-enhancing technology. One disease causes the bridge Disease in the bridge structure,radii shoes, the need to take measures to reinforce the repair or replacement. Bridge strengthening works should normally follow the following procedures: Reliability Second, bridge strengthening the general process 2. Grouting, the cracks into the resin or cement-like material to improve its water resistance and durability. Epoxy grouting material is a major, multi-use low-voltage low-speed injection method. Epoxy injection method and the nail and use, can enhance the integrity of fracture site, to prevent the cracks continue to develop a good way. Enhanced bridge repair and reconstruction can be divided into cracks in the reinforcement of the bridge increased, here the characteristics and possible applications. 3. Filling method, which is a suitable method of repair wide cracks, the concrete practice of cutting a groove along the crack, and then fill in the slots of various bonding materials embedded, such as cement mortar, epoxy mortar, expansive cement mortar, silicon resin, asphalt and chemical reinforcing agent. Bridge structure should have sufficient strength to withstand the effects of its gravity and additional forces on; structure of ministries must have sufficient rigidity, so that it loads do not cause excessive deflection and deformation; structure of ministries size must have the appropriate size of the axial pressure so that it does not occur when the buckling of components, loss of stability. At the same time the structure must have a high durability. The role of the randomness of the load,ghd planchas, the discrete nature of material strength, manufacturing and construction quality of dispersion, assumed that the approximate calculation, resulting in long-term use of the bridge structure of the course of disease, the specific reasons are as follows: III,mulberry, bridge strengthening enhancement technology 1. Surface treatment, micro-cracks in the surface of coated filler and waterproofing materials, to improve its water resistance and durability. For the crack width changes, try to use flexible in the material. Structural reliability evaluation - to determine reinforcement - Reinforcement - Shi D organizational design - construction - acceptance. 6. Poor geological conditions, such as landslides, as a result of the bridge have soft disease. 1. The original design load is low, the traffic after the development of vehicle load increases, the bridge due to diseases arising from insufficient carrying capacity. Repair cracks in structures intended to restore the waterproofing and durability, the main technologies: 5. Floods and other natural disasters have damaged the bridge. 3. Bridge construction of poor quality, failure to implement the design requirements and construction regulations. 4. Do not attach importance to the bridge maintenance work late, have not had time to eliminate the disease. identification, mainly for diagnosis of diseases of the structure's condition. Like prescription reinforcement, reinforcement design is the existing norms and standards for the deepening of the process of reinforcement. Reinforcement is reinforced by the design of reinforced structures reinforced by the construction process, for large structural reinforcement, to ensure quality and safety, construction, construction design should be prepared before.
