Completion of Ballastless Turnout Construction at Chaonan Station of Shantou-Shantou Railway
April 8，With the completion of the pouring of the last group of ballastless turnout，The concrete pouring of 8 sets of ballastless turnouts at Chaonan Station of Shantou-Shantou Railway was successfully completed，It became the first station on the Shantou-Shanwei Railway to complete the construction of all turnouts.。
Turnout is the line connection equipment that enables train Vehicles to transfer from one track to another，Usually laid in large quantities at stations，With the turnout，It can give full play to the carrying capacity of the line.。" Ballastless turnout construction requires high precision.，Construct from the base plate，And then to the fine adjustment of the turnout assembly of the track bed slab，Accuracy up to sub-millimeter level。" According to Wei Hui, the construction manager of Chaonan Station of Shantou-Shantou Railway Project of the 11th Bureau of China Railway,，The speed of Shantou-Shantou Railway is 350 kilometers per hour.，To ensure smooth running of the train，Before laying the turnout，The project management personnel shall strictly follow the design mileage、The elevation is continuously rechecked.、Positioning。The project also avoids high temperatures during the day.，Fine adjustment of turnout shall be carried out at night when the temperature is low，Concrete is poured late at night when the temperature is lowest.，And a canopy and a maintenance device are additionally arranged.，Ensure the laying quality。
After more than two months of hard work,，The ballastless turnout construction task of Chaonan Station was successfully completed，Long rail connection conditions have been met.。Next step，The project department will take the construction quality of Chaonan Station as a reference.，Accelerate the construction of ballastless turnouts at Shantou South Railway Station and other stations，Create favorable conditions for track laying of the whole line。" At present, all the equipment for laying long rails has been on the scene.，When the working face meets the construction conditions，We will lay 500 meters of steel rails.。" Wei Hui said。
Shantou-Shantou high-speed railway is an important part of the national coastal high-speed railway corridor.，The project construction is progressing in an orderly manner.，Shantou Section Main Line Control Project——The shield main line of Shantou Bay Submarine Tunnel has been excavated for more than 1252 meters.，The mining method section on the south bank has been excavated for more than 5612 meters.；Box girder erection has been completed from Shanwei to Shantou South Railway Station，Ballastless track construction is being carried out。Main structure of Shantou South Station and Chaonan Station、Steel structure、Secondary structure、The main structure of the canopy has been completed.，The interior decoration of the station building is under way.、Curtain wall installation、Construction of platform canopy imitating clear water and mechanical and electrical installation, etc.。
The construction of Shantou Railway Station and station area is in full swing
The newly-built Shantou Station and Station Area Project is located in Longhu District of our city.，After completion, the total scale of the platform will increase from 2 sets and 4 lines to 11 sets and 24 lines in the future.，From east to west, there are 4 sets and 9 lines in Shantou-Shantou high-speed parking lot.、Guangzhou-Meizhou-Shantou general speed train yard 4 sets 10 lines，As well as 3 sets and 5 lines in the East City of Guangdong.，Designed maximum speed of 350 kilometers per hour，Become the largest in eastern Guangdong、Railway hub station with the most complete traffic connection function。
Walk into the project construction site，As far as the eye can see，Vehicle/ 'target='_blank' style='color:blue;'>Transport Vehicles shuttle back and forth on the construction site alternately.，The yellow Tower Crane stands tall.，Transport construction materials with long arms。Piers and columns sprang up one after another，The buckled brackets are crisscrossed.，The workers are distributed in various working areas.，Construct the main structure below the rail bearing layer of the station building and the main structure of the north-south drop-off platform.，The whole scene is magnificent.。
According to introduction，The main building of the new Shantou Railway Station is designed as a three-storey structure.，Elevated waiting floor，The platform layer located on the ground is the rail bearing layer.，As well as the underground exit layer and the urban corridor layer.。The total building area is about 370000 square meters.，East Station Building of Phase I、Construction of West Station Building of Phase II Reconstruction and Expansion Project，The whole station building adopts the streamline of upper entry and lower exit.，Runs through the east、West Square，Achieve double-layer interconnection、Integration of station and city。
Jiang Zhaowei, head of the five departments of the new Shantou Station and Station Area Project Department of China Railway Construction Group, told reporters.，At present, there are more than 1600 people in the field.，24-hour shift operation。The steel column of the rail bearing layer of the station building has been installed by April 11.；The north-south drop-off platform has completed the installation of most of the frames.，It is expected that the north-south viaduct concrete pouring will be completed in June.，Prepare for the construction of the entire elevated waiting floor。
After the reconstruction of Shantou Station and station area is completed，Shantou Station will be connected to Shantou-Shantou Railway、High-speed railways such as Shantou-Zhangzhou Railway and inter-city rail transit in eastern Guangdong，At the same time, it achieves seamless connection with a variety of urban traffic.，Build an integrated transportation hub in eastern Guangdong。
In addition，East Guangdong Intercity Railway " One ring and one ray " Has been fully rolled out，Longhu Affiliated Middle School of Shantou-Chaoshan Airport Control Project、Times Square and other sites to promote multi-point；The section from Chaozhou East to Shantou involves bridges.、Full mobilization of tunnel works。The diaphragm wall of the north open-cut section of Shantouwan Tunnel of the Shugang Railway Control Project in Guangzhou-Macao Port Area has been completed.，Shield shaft construction is being carried out；Construction of 2 inclined shafts in Nanan Mine Method Section completed，The main line tunnel has been excavated for 385 meters in total.。
