Reinforced Concrete (RC) and Prestressed concrete (PC) structures
We are one of the few companies specializing in structural design of reinforced concrete according to TCVN 7888: 2014, 22TCN 272-05 (AASHTO LRFD 1998), TCVN 11823: 2017 (AASHTO LRFD 2012). PC products designed by TVEn have been manufactured by professional units ((Beton Joint Stock Company 6 - formerly known as 620 Chau Thoi Concrete Joint Stock Company, Binh Minh Concrete Joint Stock Company - previously 620 Binh Minh Concrete Joint Stock Company, Dung Quat Concrete Joint Stock Company, The Gioi Nha Construction Material Joint Stock Company, Dong Thap Transport Construction Joint Stock Company...) used as a typical structure for many projects.
Some typical products include: I-section PC girder (L = 12.5m - 18.6m - 24.54m - 33m), with design live load HL93, I-section PC girder used in rural traffic (L = 6 ÷ 18m , 22m) with design live load H2.8 ÷ H10, H13, 0.5•HL93, 0.65•HL93; Piles of centrifugal pipes of various types (Φ300 ÷ 1200mm), PC W-section piles (300 ÷ 1200mm), PC square piles of small size (120x120mm ÷ 350x350mm) ...
In 2009, we have designed and finished new products, PC inverted T section girders L = 20m, 25m, 33m with design live load HL93 under 22TCN 272-05 specification. This is the first product we have in Vietnam with we are the author of the design. The products have been manufactured, tested and initially applied in projects. Compared to the hollow beam currently popular in the construction market, the inverted T section girders is product low cost (down to 30 ÷ 40%) as well as low architectural height, contributing to the small construction The bridge beauty beauty rich country.
In addition, we are also very professional in calculating reinforced concrete structures with Vietnam standards, industry standards, ACI (USA) & BS (UK) in order to meet the requirements of customers.
Steel structures
TVEn engineers have designed many steel structures as per specifications 22TCN 272-05, AASHTO LRFD, AISC LRFD. Some representative typical construction projects include: Cong Vong steel girders temporary bridge (An Giang), Ong Au steel truss (Bailey style) temporary bridge (Dong Thap), Muong Trau steel truss (Bailey style) temporary bridge (Dong Thap), Cai Chai steel truss (Bailey style) temporary bridge (Dong Thap), Nuoc Trong steel truss (Bailey style) temporary bridge (HCMC - Long Thanh - Dau Giay Expressway construction project), guard house using steel frames structure (Vung Tau), control building using steel truss structure (Vung Tau), parking station using steel frames structure (HCMC), Bailey style steel truss used in many construction projects ...
Circular RC pipe
TVEn is one of a few pioneer companies in Vietnam who firstly designs the circular reinforced concrete pipe as per specification 22TCN 272-05 (AASHTO LRFD 1998) satisfying design live load HL93. We have spent many hours of hard working for researching pipe products which have the most economical cost. Some professional companies having been successfully using these products in practice include: Binh Minh Concrete Corporation, An Giang Real Estate JSC. Moreover, all of these products have been tested by the three-edge bearing tests and successfully passed, this proves the safety of reinforced concrete pipes designed by us.
Sheet piles wall
The design of retaining wall along the river bank is a job that requires extreme caution. The fact that many practical construction projects in the area of the Mekong Delta having problems requires us to pay proper attention to the calculation for the construction safety. TVEn is currently using our own computer programs which is based on three limits state method to evaluate properly and precisely the sheet piles wall solution in contruction projects.
Special structures
-
Stressing platform and formwork used in construction projects to cast pretensioned PC and post-tensioned PC girders of Can Tho bridge construction project, East-West Highway construction project, Phu My bridge construction project, 620 Long An Concrete JSC, Dong Thap Transport Construction JSC, HCMC - Long Thanh - Dau Giay Expressway construction project ...
-
Formwork and supporting system for piers construction (not including main towers) at Phu My bridge. The special Tie Down pier is extremely complex: the pier is high and slender (approximately 42m high), vertical load is large (approximately 2,400 Tf), lateral load is large (approximately 100 Tf). In the supporting system, we have firstly used friction for supporting all loads to reduce construction cost. While at Rach Mieu project, bored piles foundation had been used to support the loads of Tie Down pier, at Phu My project we only need driven piles to support the loads.
-
Crane rail beam foundation on driven piles solution is used at Phu My bridge project.
-
Mobile scaffolding system is used at the Phu My bridge project to support for the assembly of water supply pipes system, electricity system on bottom of the bridge.
-
Reinforcing couplers used in joining steel bars (Φ16 ÷ 32mm) are mass produced at Binh Minh Concrete JSC.
-
Load test supporting system, friction load test system and high strength steel strands elongation load testing platform.
