Recently, the test pile of G236 Qingtong River Bridge reconstruction project was successfully drilled, and the successful drilling of the first pile foundation provided experience and reference for the subsequent drilled pile construction, and also laid a solid foundation for the comprehensive construction of the project。

　 It is reported that the test pile length of 15m, 5m into the rock, is expected to be 25 holes, 30 days to complete the concrete pouring。After the end of the pile test, the construction summary will be organized to determine the construction technology, and provide technical support for the later large-scale construction of pile foundation。It is planned to complete the construction of 24 pile foundations and substructure in the water before the year, and it is expected to complete all pile foundations in April next year, and the entire project period is about 36 months。

　 The design of G236 Qingtong River Bridge reconstruction project starts from the intersection of G236 and Guangrong Road, the starting point is K0+000, and it crosses the Qingtong River southward along the current S321 highway and ends at the bridge head of Qingtong River. The end point is K2+165. The total length of the route is 2.165km, the total cost of the project is about 200 million yuan。The construction of the project is of great significance to open up the broken road, strengthen the communication and connection between the two cities, give full play to the scale effect and the overall effect of the road network, and promote the economic development of the two cities。
