The construction drawing has been transferred from the Zhoushan Municipal Transportation Bureau (Zhoujiao [2016] No. 228) Reply
The reconstruction and expansion of the Zhoushan-Dinghai Highway Xincheng Bridge began at the intersection of Linchang Road and Haitian Avenue on Zhoushan Island, along the current Linchang Road, passing through Tangan Island, and finally at the intersection of Linchang Road and Taoyuan Road on Changyi Island for the purpose of reconstruction and expansion. engineering. The entire line is two-way six lanes. The original Xincheng Bridge was reconstructed as a one-way three-lane road as the left site. A one-way three-lane bridge was added on the right side of the Old Bridge as the right site. The width of the old and new bridges was 16.5m. The total length of the route is about 1.805km and the special bridge is 1362m / 1 (the main bridge is a steel box tied arch bridge with a main span of 148m; the approach bridge is a prestressed T beam with a standard span of 30m), and the main line plane crossover 2 At the office, the auxiliary road intersects at one place.
Technical Standards: The design adopts the first-grade highway combined with the urban road standard; the design speed is 60 km/hour for the main line and 30 km/hour for the auxiliary road; the bridge and culvert design has an automotive load rating of Highway-I; and the navigation rating: 500-ton-class seagoing vessel, with net navigation height 14.5m, net width 106m; other technical indicators are implemented according to relevant national standards and norms.

Thermosiphon Solar Collector
Most cost-effective Solar Collector.
Water is heated inside of tubes directly, so the efficiency of LPC solar collectors is the highest.
LPC vauum tube collector is an economic selection for hot water generation and process heating system. Due to succinct collecctor structure with Vacuum Tubes and manifold box, it has long operating life time but short pay-back period.
LPC vacuum tube collectors are wildly used and installed for large scale hot water heating system, especially for hotel, appartment, hospital, swimming pool, industrial process heating system, etc.. LPC vacuum tube collector system has been the most cost-effective solution for large scale solar hot water heating with temperature below 75 degree celsius.
We can not only provide LPC collectors, we can also provide you whole solar water heating solution with LPC collectors.
