🌟❄️The Winter Solstice has arrived! It's the day with the shortest daylight and longest night in the Northern Hemisphere. This ancient festival holds deep significance. It marks a pivotal moment in nature's cycle, where the darkest night gives hope for the return of longer days and the coming of spring. 🌱 Families often gather to enjoy delicious traditional foods like dumplings. It's a time for warmth, love, and togetherness. Let's embrace this special occasion, feel the chill in the air, and look forward to the renewal that follows. Happy Winter Solstice! 🥟💖 

This Winter Solstice at Boyoun was truly unforgettable! 🥟 In the dumpling-making area, it was super lively! We kneaded the dough, prepared the fillings, rolled out the wrappers and wrapped the dumplings in perfect harmony. 💪 While our hands were busy, our mouths were not idle either. We shared interesting stories from life and work, and the laughter filled the air. 😄 Look at those dumplings we made! Some were like gold ingots, wishing for wealth, and some were like lucky pouches, bringing good fortune. 💰 Soon, the tables were filled with neatly arranged dumplings, just waiting to be cooked and bring more joy. And there was also a fun "DIY Candied Hawthorns" part. We made the syrup ourselves and carefully coated the fruits. When the sweet and sour candied hawthorns were ready, the sweet smell made us feel like we were back to our happy childhood. 🍭 It really pushed the joyful atmosphere to the peak! After the dumplings were cooked, we gathered to taste our own hard work. Each bite was not only delicious but also full of the warmth of unity and friendship. 💕 Although it was cold outside, in Boyoun, we were surrounded by the warmth like spring. Food, laughter, and gatherings made this Winter Solstice unforgettable. 🥰  #Winter_Solstice #Warmth_In_Winter #Traditional_Festival

🚀Large-size segment box girder's transportation and hoisting challenges have long been a hurdle. We introduce the large-cantilever segment prefabricated composite-section spine beam concept. It divides the box girder into "core segment box girder" and "prefabricated cantilever", with research on its structure, connections, and prestressing system. From sectional design to connection methods and prestressing, we're paving the way for better wide-span bridges. 🏗️ 📣 Take Action: Join the conversation and share this article with your fellow engineers and bridge enthusiasts!

🌉✨ Some Sharing on Cantilever Form Traveler Design! 🌉✨ When it comes to designing this essential component, the first hurdle is determining the segmented length of the cantilever casting. Long segments speed up construction but demand larger equipment, while short ones mean more work yet smaller gear. Usually, it's around 3- 5m, with a max of 8m. 📏 The cross-section also matters! For wide bridges (over 15m) with double or multi-box structures, two form travelers might be the way to go for added flexibility. 🌉 The overall design concept is a multi-faceted gem. We aim to reduce self-weight with smart choices like high-strength, lightweight steel and clever structural designs. 💪 Hydraulic and screw jacks, along with centralized control, cut down construction time and labor. The formwork is both stiff and durable, ensuring top-notch concrete quality. 🚧 And don't forget a comfy workspace with a sunshade and rain shelter! ☂️ Plus, it's adaptable to different box girders. Load calculations are a big deal too! We've got specific coefficients for different scenarios and a detailed breakdown of all the loads. 📈 Different load combinations are used for strength, stability, deformation, and movement checks. In a nutshell, an optimized cantilever form traveler design is the key to building amazing bridges. It's a complex dance of factors, but when done right, it speeds up construction, boosts quality, and keeps everyone safe. 👏 🔗 [Link to further reading or resources: https://bit.ly/41l60d5] 🌐🌉 #Bridge_Construction #Cantilever_Form_Traveler  

🌉🚗 Bridge Expansion Joints: Ensuring Smooth Travel & Structural Integrity 🛣️🔧 Ever wondered how bridges can withstand extreme temperatures, heavy traffic, and even earthquakes without crumbling? The answer lies in the clever design of bridge expansion joints! Let's dive into the science and understand their importance: 🔹 **The Basics of Bridge Movement:** Bridges are subjected to various forces that can cause them to expand or contract. Temperature changes, especially, can cause significant movement as materials like steel and concrete expand and contract. 🔹 **The Role of Expansion Joints:** These joints are designed to accommodate these movements. They allow the bridge to bend, twist, and move without causing stress or damage to the structure. 🔹 **Types of Expansion Joints:** - modular expansion joint - steel expansion joint  - corrugated expansion joint  - single-joint expansion joint  - carbon seamless expansion joint 🔹 **Why They're Essential:** - **Prevent Structural Damage:** By allowing for natural expansion and contraction, they prevent stress that can lead to cracks or collapses. - **Ensure Safety:** They maintain the integrity of the bridge, ensuring it remains safe for all users. 🔬 **Join the Conversation!** Comment below with your questions about bridge expansion joints or share your experience with a bridge that you think has exceptional expansion joint design! 🔗 [Link to further reading or resources: https://bit.ly/4fVA3wv] 🌐🌉 🌉 Stay curious and keep bridges safe! 🌟😊

🎉Great News! The #Saribas_Bridge in Malaysia has reached a significant milestone! 🌟 The main bridge was successfully closed at 8 pm on November 25th, as the final batch of concrete was poured into the formwork. This marks the final sprint of the project, hastening its completion and opening to traffic. 🚧 Located in Pusa Town, Betong Division, Sarawak, Malaysia, this 1,550-meter-long bridge with a 200-meter maximum span of the main bridge features a combined structure of continuous rigid frame and continuous beam. The continuous rigid frame is a cast-in-place prestressed concrete box girder with unique characteristics. 🌉 The construction wasn't easy. Challenges like driving large-diameter and long steel pipe piles in water, building high-pile caps with prefabricated concrete bottom cofferdams on water, and asymmetric cantilever construction with large spans, along with extremely complex construction environment due to irregular tidal changes (a maximum tidal range of over 5 meters) made it highly difficult. But our project team was up to the task! They strictly followed quality control requirements, monitored every step from raw material inspection to technical scheme demonstration and construction dynamic monitoring. And thanks to effective organization, the engineering quality and construction schedule progressed smoothly. 👍 Boyoun on-site guidance for key nodes like the assembly and movement of cantilever form traveler and carried out all-round and whole-process supervision. The professional services earned them high praise and honorary certificates. 👏 Upon opening, this bridge will boost regional integration and economic and social development in the area. In the context of the "Belt and Road Initiative", it will surely become a remarkable business card for "Overseas Boyoun". We can't wait to see this bridge fully operational and making a positive impact! 🇲🇾💪 Know more details 👉 https://bit.ly/4fOY08w communicate with us 👉 https://lnkd.in/giKcdRVf
