Aluminum formwork system for building
The aluminum formwork system for building was founded earlier in the United States and is a new generation of green formwork technology. It is mainly composed of formwork system, support system, fastening system, and attachment system. After decades of development and improvement, the technology of building aluminum formwork systems has matured and applications have become more extensive. Dozens of countries around the world such as Europe, America, Japan and South Korea, the Middle East, Southeast Asia, and Brazil have been widely used in construction. In recent
Ultra high performance concrete(UHPC)--- AT-UHPC
AT-UHPC,Gaobaotan UHPC products. 1.5h expansion ≥ 600mm, 7d strength ≥ 150MPa. Improve the construction performance of traditional UHPC and realize the standardized production of House-building formwork system in large quantities and long-distance harmless transportation. Facade elements on UHPC base are resistant to environmental influences. Facades or facade elements can be made very thin. By thin-layer Construction Materials and thus low weight of these elements are easier to install.
Ultra high performance concrete (UHPC)
Ae-uhpc, coarse aggregate UHPC product, expansion ≥ 600mm, 1-day compressive strength ≥ 90Mpa, 7-day compressive strength ≥ 150MPa, breaking the technical monopoly of SBT. Ultra High Performance Concrete (UHPC), is a high strength, ductile material formulated by combining portland cement, silica fume, quartz flour, fine silica sand, high-range water reducer, water, and steel or organic fibres. The Construction Materials provides compressive strengths up to 29,000 pounds per square inch (psi) and flexural st
All you need to know about Civil Engineering Basic Knowledge
Civil engineering is arguably the oldest engineering discipline. It deals with the built environment and can be dated to the first time someone placed a roof over his or her head or laid a tree trunk across a river to make it easier to get across. The built environment encompasses much of what defines modern civilization. Buildings and bridges are often the first constructions that come to mind, as they are the most conspicuous creations of structural engineering, one of civil
Product introduction UHPC is an ultra-high performance cement-based composite with ultra-high strength (compressive strength ≥ 120MPa, tensile strength ≥ 5MPa), high toughness and high durability Beijing Lijian UHPC core technology
Product performance A-uhpc, steam curing free UHPC product, has the characteristics of steam curing free, ultra-high strength, high toughness and low shrinkage. Technical indicators of a-uhpc products
Hydraulic Tunnel Lining Formwork construction
Tunnel Steel Formwork is a highly complex process. It includes considerations of various natures such as geology, geotechnique, organisation of the works, and economy. Above all, the safety of the workers and the users must be warranted as well as the serviceability of the tunnel on the long term. Lining methods, which are the permanent support methods for the tunnel, play the main role for keeping tunnel from collapse and provide safe quickly corroded the steel and degraded the concrete, leading to serious deterioration of the Steel Lining Tunnel.
Advantages of Steel Box Girder in Bridges
A box girder (also known as tubular girder) is a girder that forms an enclosed tube or hollow box like structure with multiple walls. The proceeding with development of roadway system all through the world is generally the consequence of awesome increment in movement, populace and broad development of metropolitan urban territories. This extension has prompt to many changes in the utilization and improvement of different sorts of scaffolds and bridges. The bridges sort is identified with giving most extreme proficiency of utilization of material and development method, for specific traverse, a
Tunneling techniques of tunnel underground construction
Tunnel Formwork are generally grouped in four broad categories, depending on the material through which they pass: soft ground, consisting of soil and very weak rock; hard rock; soft rock, such as shale, chalk, and friable sandstone; and subaqueous. While these four broad types of ground condition require very different methods of excavation and ground support, nearly all tunneling operations nevertheless involve certain basic procedures: investigation, excavation and materials transport, ground support, and environmental control. Similarly, Tunnel Lining Fo
Tunnel Lining Formwork Safety Operation Procedures
Tunnel Lining Formwork Safety Operation Procedures Tunnel lining formwork is a special equipment that must be used in the secondary lining of tunnel construction process. It is used for lining construction of the inner wall of the tunnel. There are mainly simple lining trolleys, full
The Use And Structure of Tunnel Lining Trolley
First of all you should know the structure of the trolley Hydraulic and mechanical can be selected. After analysis and comparison, the hydraulic type has low requirements for rigidity of the trolley frame, sensitive structure, light weight, low processing requirements and low elevation requirements of the laying track during construction, and is conven
Brief Introduction of Tunnel Lining Trolley
Brief Introduction of Tunnel Lining Trolley The tunnel lining trolley is a special equipment that must be used in the secondary lining of the tunnel construction process, and is used for the concrete lining construction of the inner wall of the tunnel. Concrete li
How to strengthen the steel structure?
The Custom Steel Structure reinforcement design can use the linear elastic analysis method to calculate the effect of the structure, and should comply with the relevant regulations of the current standards. The reinforcement design of the structure should be closely integrated with the actual construction method, and effective measures should be taken to ensure that the new components and components are reliably connected to the original structure, and the new section and the original section are firmly combined to form an overall jo
Steel Structure Brings More Possibilities to Future Cities
Steel Mould is widely used in our lives, but it is inevitable that they will have some problems. In order to reduce the occurrence of problems, Precast Steel Moulds is necessary to strengthen steel structures. The following is a comprehensive introduction to the reinforcement of steel structures. Reinforcement of Custom Steel Structure Before reinforcement, inspection or appraisal s
