The installation of symmetrical turnouts mainly includes the following steps:
1.Preparation: Count the number of parts, check the geometry and orientation. At the same time, confirm that the strength of the beam meets the requirements (in special cases, it is necessary to replace the foundation under the track and erect the alignment). If it is a single-open type, it is similar to ordinary rails;For the cross class or Z-shaped type, it needs to be placed on the original old road according to the position of the design drawing (note that the two sides should be symmetrically arranged). After using a total station and other measuring tools to ensure accuracy, fix the base and pour concrete to complete the docking work of a pair of lanes.
2.The insertion and adjustment of turnout switches, connecting rods and other equipment is one of the key links. It is necessary to do a good job of each step of the operation carefully and patiently to ensure that the equipment can run smoothly and unhindered between the components, and maintain a certain parallelism and angle (such as the relationship between the two lines and curves that are basically parallel) to achieve the purpose of correct conversion to the target strand. 3.?Precautions: When loading and unloading the roller device, attention should be paid to the safe handling method to prevent the original accuracy and performance from being changed due to impactDuring the construction process, the relevant regulations should be strictly observed to ensure the quality of construction and personal safety. The above content is for reference only, and the specific implementation can be adjusted and optimized according to the actual situation!
