Introduction of several aspects of road and bridge maintenance

Introduction of several aspects of road and bridge maintenance


Inspection and evaluation of road and bridge maintenance: the bridges in use must be inspected and evaluated in accordance with regulations, the basic conditions of the bridges must be grasped in time, and corresponding maintenance measures must be taken. The inspection is divided into regular inspection, regular inspection and special inspection.

Methods of bridge reinforcement

Methods of bridge reinforcement


From the part of the bridge reinforcement, the bridge can be divided into the upper structure reinforcement, the lower structure reinforcement. There are common methods for strengthening the upper structure of bridges: increasing the cross-section method, pasting and strengthening method, external prestressing method, increasing the auxiliary component method and system conversion method. The common methods of bridge substructure reinforcement are: expanding foundation reinforcement method, high-pressure jet grouting reinforcement method, reinforced concrete hoop and outsourcing steel plate, etc. It should be noted that the application of these reinforcement methods is not a single, must be based on the actual situation to choose the reinforcement method or combined with each other, and before the use of these methods, must first bridge cracks, pockmarks and other diseases after treatment before reinforcement.

Bridge bearings and their functions, characteristics, requirements and classification

Bridge bearings and their functions, characteristics, requirements and classification


In the bridge structure, the bearing is the connection point of the upper and lower structures of the bridge. Its function is to transfer the load of the upper structure to the pier platform smoothly and safely, and to ensure the free deformation of the upper structure under the action of load, temperature change, concrete shrinkage and other factors, so as to make the actual force of the structure conform to the calculation diagram and protect the beam end and pier cap from damage. This requires it to have enough rice vertical stiffness and elasticity, can be the upper structure of the bridge all the load reliably transmitted to the pier, and at the same time bear the horizontal displacement, angle and deformation of the end of the bridge structure caused by the load, reduce and ease the vibration of the pier, adapt to the temperature and humidity changes caused by the expansion and contraction of the bridge structure.

Device method for counting plate rubber bearings

Device method for counting plate rubber bearings


On the general plate rubber bearing equipment cast-in-place beam equipment rubber bearing is more convenient. The construction procedure is as follows: the top surface of abutment pad stone shall be clean. If the bearing pad stone elevation interval is too large, can be adjusted with cement mortar. The center shall be marked on the bearing pad stone according to the planning drawing, and the center of the rubber bearing shall be consistent with the center line of the bearing pad stone during equipment, so as to ensure the bearing in place accurately.

Maintenance and cleaning of rubber molds


Pollution erosion on the surface of the rubber cavity The pollution erosion on the surface of the cavity is mainly manifested in the appearance of stains and moire, the agglomeration of pollutants and the corrosion of the cavity. The influencing factors are mainly related to the composition of the compound formula, vulcanization conditions and environment, mold material and processing. Natural rubber contains non-rubber hydrocarbon substances such as lipids, proteins and inorganic salts, which are most likely to contaminate the mold cavity during vulcanization. Halogen-containing rubber of synthetic rubber will produce halogen compounds during the vulcanization reaction to cause contamination of the mold cavity. For example, chlorine and HCl will be produced during the vulcanization of chloroprene rubber to erode the mold cavity. HF will be produced during the vulcanization of fluororubber to corrode the mold cavity. In the formula

Fire drill


In order to further strengthen the awareness of fire safety and enhance the ability to respond to emergencies. Our company organized more than 50 personnel to carry out fire emergency evacuation and fire fighting drills to effectively strengthen the fire safety work of the whole plant. Through the exercise, the personnel of various departments have improved their emergency response capabilities and actual combat experience in responding to sudden fires, laying a good foundation for better protecting the lives and property of personnel.
