Tianyuan Construction Group to Complete China's Longest Bridge Jacking Reconstruction Project

Tianyuan Construction Group | March 26, 2022

Tianyuan Construction Group, one of China's top 500 construction companies, will complete the renovation of Yihe Bridge, located on Beijing Road in Linyi city, Shandong province, in early April, concluding China's largest and longest bridge jacking reconstruction project by area and length respectively.

Located on Beijing Road in the south of the city, Yihe Bridge was 1,210.72m-by-23m with a jacking height of 1,050m. After renovation, it will be 1,792m-by-52m.

"The successful completion of the Beijing Road Yihe Bridge jacking project will greatly ease the traffic situation between Beicheng New District and Hedong District" 

Li Baoqiang, charge of the reconstruction project from Tianyuan Construction Group

Reconstruction involves the simultaneous lifting of two new 15m-wide bridges on the north and south sides of Yihe Bridge. The entire upper structure of the old bridge will be lifted by 2.57m. The lifting of the northern and southern sections was completed in November 2021 and February 2022 respectively.

Currently, the cover beam of the southern section is being heightened and is on track for completion in early April. The entire project is planned to complete before October 1, 2022, which will ensure that traffic on both sides of the Yi River is smooth, spurring the regional economy.

Main challenges faced
In order to ensure safety during the bridge jacking process and ensure that equipment is stable, 19 sets of limiters were installed on the bridge deck, preventing vertical and horizontal displacement of the beam body during the jacking process.

Beijing Road Yihe Bridge was lifted via an alternate lifting process. This process involves two sets of jacks being lifted synchronously underpinned by support. This method allows for continuous lifting of the entire jacking process, ensuring efficiency and control. Furthermore, a PLC hydraulic synchronous control system was incorporated to ensure synchronization and structural safety.

Reasons for bridge jacking
As Beijing Road Yihe Bridge is a transportation hub connecting New Beicheng and Hedong districts, it is important that it functions well and safely. Bridge jacking is essential for the repair and maintenance of bridges.

In November 2019, dynamic and static load tests were carried out on Beijing Road Yihe Bridge. The tests showed that the bridge met bearing capacity requirements and had sufficient safety reserves. Therefore, there was no need to demolish the old bridge.

To meet flood control requirements, in which the minimum elevation of the bottom beam has to be 0.8m higher than the 100-year flood level of 72.36m, the superstructure of the old bridge also had to be raised by 2.57m.

Furthermore, the current bridge is supported by a 30m-wide simple support box girder. However, as there are many piers and columns under the bridge, a 60m-wide girder was recommended instead for a better bridge view.

Euclid Launches Three New Admixtures at World of Concrete

Euclid | February 17, 2022

Euclid Chemical, a leading manufacturer of concrete and masonry construction products, announced the launch of three new concrete admixtures at this year's World of Concrete—the concrete industry's largest event for building professionals. The following high-performance admixtures were developed to respond to the rapidly evolving needs of construction and concrete professionals: EUCOSHIELD™ An integral finishing admixture, EUCOSHIELD is a ready-to-use liquid admixture designed to be used as an integral finishing aid that prevents rapid moisture loss from the concrete surface by binding the internal water in the pore structure. It is especially effective when concreting operations must be performed in direct sun, wind, high temperatures or low relative humidity. EUCOSHIELD can also be used to reduce excessive bleeding and segregation of concrete or mortar. Containing no added chlorides or chemicals known to promote the corrosion of steel, EUCOSHIELD is compatible with most other admixtures commonly used in concrete, including air entraining admixtures, polycarboxylate-based HRWR admixtures (superplasticizers), conventional water reducers and retarders. EUCON ECO-STRENGTH™ A strength-enhancing admixture, EUCON Eco-Strength improves both early- and late-age strength development in concrete. Based on a highly engineered admixture technology that facilitates cement hydration, EUCON Eco-Strength enhances strength development and allows for sustainable construction practices to be achieved through possible total cementitious content reduction. Maintaining compressive strength development equivalent to that of a reference mix containing more cementitious is important in all construction projects requiring CO2 emissions and total embodied energy reduction. EUCON Eco-Strength is particularly effective where heat is present while curing, allowing earlier stripping of forms or restoring the serviceability of concrete repairs. EUCON® AM-10L A liquid integral crystalline waterproofing admixture, Eucon AM-10L is formulated to interact with concrete capillary pore structures to provide a system that greatly reduces the permeability of concrete through the formation of tiny crystals that block the pores. It can also seal microscopic cracks and work in tandem with other products like sealers to create a structural waterproofing system. EUCON AM-10L can be used in both above- and below-grade applications. About Euclid Chemical Headquartered in Cleveland, Ohio, Euclid Chemical has served the global building market for more than a century as a leading manufacturer and supplier of specialty products and technical support services for the concrete and masonry construction industry. Euclid Chemical's expansive product line includes admixtures, fiber reinforcement, concrete repair products, flooring materials, decorative concrete systems and more.
