　　At 4:00 am on August 8th, the pouring of the bottom and web plates of the third cast-in-place box girder on the right side of the Wen'anxi Interchange of the ZT8 section of the Jingde Expressway officially began, marking another breakthrough in the construction of the ZT8 section of the Jingde Expressway. The construction focus has gradually shifted from the construction of the lower structure of the bridge to the construction of the upper structure of the bridge. It is reported that the third link on the right side of the main bridge of Wen'anxi Interchange is a cast-in-place beam of the first link of ZT8 section of Jingde Expressway, with a structural form of 4 * 35 meters, a single box five room equally high prestressed cast-in-place beam, and a total length of 140 meters. In order to ensure the quality assurance of the first section of the ZT8 section of the Jingde Expressway, the project department held a technical safety briefing meeting and made sufficient preparations in terms of raw material storage, personnel preparation, construction machinery, transportation routes, concrete pouring sequence, emergency plans, etc., to ensure the construction quality and safety of the cast-in-place beams.According to the different forms of bridges, the daily maintenance work of the drainage system includes (1) if the drainage pipes and channels on the bridge deck are blocked, they should be promptly unblocked and kept unobstructed regularly. The lower end of the drainage pipe should be exposed 5-10cm above the bottom of the upper structure. (2) When the waterproof layer of the beam bridge is damaged, it should be repaired in a timely manner. The waterproof layer should be made of materials with good waterproof performance; When laying the waterproof layer, it should be carried out at a temperature not lower than+5 ℃. (3) The bridge deck should maintain a transverse slope of 1.5% to 3.0% to facilitate bridge drainage; Whether the facilities of the system, such as the pumping pump, are working properly, and if there is any blockage, they should be cleared in a timely manner. If there is any damage, they should be replaced in a timely manner. Commonly used specifications can be shipped on the same day to ensure quality, and come with a test report and certificate of conformity when leaving the factory. Large factories, with quality assurance, must customize according to the drawings. Generally, it takes less than seven days to make molds for circular drainage pipes and ship them, while rectangular pipes take slightly longer due to their complexity compared to circular pipes. It takes 15 days from mold making to shipment.
