With“Road、Bridge、Tunnel”Full end of offline project，Hangzhou-Wenzhou Railway Phase II Project Enters Ballastless Track Construction“Go all out”Phases，More than 200 ballastless track construction workers on the whole line are under the scorching sun.、Step on the heat wave and fight on the front line。
It is reported that，As the last process before track laying，Ballastless track construction requires very high precision control.，In particular, the installation error of some fasteners of the ballastless track bed must be accurately controlled at 0.Within 5 mm。Construction site of ballastless track bed across Hangzhou-Huanghai Railway Bridge，A group of workers armed with vibrators are standing next to the concrete mixing tanker.，Carefully place the concrete on the track bed below the sleepers and spread it out。
Zhang Junqing, Deputy Field Commander of Hangzhou-Wenzhou Railway Phase II Construction Command of Zhejiang Communications Group, said.，The project is scheduled to open to traffic in June 2024.，At present, it is the sprint stage.，The headquarters will organize the construction scientifically.，Make sure to avoid summer heat、Make no mistake in construction。So far，Hangzhou-Wenzhou Railway Phase II Project Completed Annual Investment 15.7.3 billion yuan，Accounting for 74% of annual investment plan.91%，Start tired and finish 65.9.1 billion yuan，94% of total investment.69 of 800 million yuan.53%。

At the construction site of Huzhou East Railway Station of Huzhou-Hangzhou Railway，The flat and wide ground of the station building has begun to take shape.。In the heat wave，Nearly 100 workers are installing steel bars on the ground cushion.。
“At present, the concrete floor slab of the underground overhead floor is under construction.。”Relevant person in charge of Engineering Department of Huhang Railway Construction Command of Zhejiang Communications Group introduced.，“The high temperature of concrete construction in summer will affect the quality of buildings.，Therefore, concrete pouring is usually arranged after 6 P. m.，During the day, the workers are mainly responsible for installing steel bars.、Reinforce the formwork、Earth fill cushion。”However, prolonged exposure to the sun and high temperatures are likely to cause ultraviolet allergy among workers.，For this reason，The headquarters took the lead in taking a series of safety measures to prevent heatstroke and cool down.，Actively carry out heatstroke prevention drills，Reasonably arrange the operation period，Mung bean soup was prepared at the construction site.、Cool oil、Huoxiang Zhengqi Water and other products for relieving summer-heat and cooling，Ensure the health of front-line construction personnel。
It is reported that，Huzhou East Railway Station is expected to be put into operation in December 2024.，The total investment is about 3.500 million yuan，Building area 2.80 thousand square meters，With 3 sets of 7 lines，It is estimated that 4 million passengers will be sent in the future.，It is an important transportation hub for Huzhou to deeply integrate into the half-hour economic circle of the Yangtze River Delta.，It is also the entry of Wuxing District of Huzhou.“Cross three high-speed railway，Tiezi Huantong No.4 Expressway”Key node projects in the era of big traffic。

Construction site of Jinjian Railway Project，Welding spatter、There are many cranes、Vehicle shuttle、The machine roared……The hot summer sun“Roast”Under the test，The enthusiasm of more than 3000 participants in the whole line of the project has not diminished.。
According to introduction，Xin'anjiang Bridge is currently in the construction stage of the main pier body pouring.。Facing the hot weather，Command plans ahead，Keep an eye on the weather.，Strengthen special inspection of working environment in high temperature weather，Supervise and urge the construction unit to implement heatstroke prevention and cooling measures，Organize and carry out training on heatstroke prevention and cooling knowledge，Explain operation protection in hot weather and emergency treatment measures for heatstroke，Ensure the safe and orderly progress of project construction。So far，Annual accumulative investment completed: 8.7.2 billion yuan，Accounting for 51% of annual investment plan.29%，The project has been completed 47.7.2 billion yuan，40% of total investment.03%。

It is ten kilometers from Toumen Port Station of Jintai Railway to Toumen Island.，More than ten“Takumi Vanguard”Members are conducting a final review of the upcoming Toumen Phase II project on the island.。“Now there are almost 40 on the island.℃High temperature，With strong winds of force 6 to 7，Like a heated hair Dryer.，The sweat from the body was dried.，Sometimes it's too hot to breathe.。”Wang Zhengbing, senior engineer of Jintai Railway Construction Command of Zhejiang Communications Group, said.，“Toumen Island has more than 200 days of force 6 gale weather throughout the year.，Effective operation time is less than 150 days。Therefore, we must complete the final review before the start of the offshore typhoon season.，Ensure that the project starts on schedule。”
It is reported that，Toumen Port Phase II Shangdao Project is led from Toumen Port Station of Jintai Railway Toumen Port Branch Line Phase I，It extends eastward to Toumen Island.。The whole line is about 14.5 kilometers，There are 2 stations in total，Reconstruction of one existing Toumen Port Station、Newly build one east station of Toumen Port。The total construction period of the project is about 3.5 years，The total estimate is approximately 40 percent.6.5 billion yuan，After completion，For the construction of multimodal transport system along Jintai Railway、Get through the railway to the island“The last mile”、It is of great significance to activate the freight transport capacity of Jintai Railway.。

Although the builders in Xiawan No.1 Tunnel of Qu-Li Railway Phase I Project avoided direct sunlight,，However, the high geothermal and humid working environment still poses a test to the construction.。Because the space in the tunnel is relatively closed.，The heat generated by high-power machinery is difficult to dissipate.，The temperature in the cave has been as high as 40 for a long time℃。
It is reported that，In order to balance construction progress and worker safety,，The headquarters reasonably adjusted the construction time period and construction process.，The excavation is realized、Slag tapping、Stand、Seamless connection between shotcreting and anchoring processes，Ensure that two construction cycles are completed each day。So far，Quzhou-Lijiang Railway Phase I Project Completed Annual Investment of 5.5.6 billion yuan，46% of annual target.33%，Start tired and finish 33.93.3 billion yuan，Accounting for 37% of the estimated total investment.35%。(Gao Tianfeng、Shen Shuoyang、Zhou Rui、Jin Chenhong、Xia Yuting、Chen Yining)
