Construction of three ship locks in Beijing's sub-center begins
[Overview] As an important hub for waterway transportation, the Yulinzhuang and Gantang locks on the Beijing-Hangzhou Grand Canal section in Tongzhou have entered the full construction stage, and the Yangwa lock has entered the survey and design stage. It is expected that all sections will be navigable by June next year!
As a crucial hub for navigable waterways, the Yulinzhuang and Gantang ship locks on the Tongzhou section of the North Canal have now entered the full-scale construction phase, while the Yangwa ship lock has entered the survey and design phase. It is expected that all will be navigable by June next year!
The construction of these three ship locks is fundamental to achieving full navigation on the Tongzhou section of the North Canal and will also improve the transportation infrastructure of the city's sub-center.
Beijing Zhenchong Engineering Machinery Co., Ltd., as a local enterprise, is honored to contribute to urban construction. In this project, the underground crushed stone fill for each section is vibrated and compacted using the combined action of high-frequency vibration from the vibratory hammer and high-pressure water jets. This process is repeated, filling and compacting, until reaching ground level.
This creates a large-diameter, highly compacted crushed stone pile in the foundation, achieving the effect of strengthening the soft foundation. In the following two weeks, nearly 4,000 vibratory stone columns will be driven into this 10,000+ square meter foundation pit to improve the bearing capacity of the foundation.
Currently, the project is undertaking construction of the 104-meter section of the main structure of the ship lock. The foundation treatment for the entire lock chamber structure will be completed by the end of this month, and the lock bottom slab will be fully completed by the end of the year. It will be navigable by June of next year.
According to the introduction, the Yulinzhuang ship lock will serve as the waterway passage between the Gantang and Yangwa locks, enabling ships to overcome the head difference between the upstream and downstream of the river lock and pass safely, smoothly, and quickly.
