In the construction application of prestressing plastic corrugated ducts in tropical and maritime climate regions such as Thailand, their core functions and advantages are consistent
There are always some small problems with prestressed anchorages during construction. Here, we have done sorting and analysis and listed four common problems and solutions
Rubber seals are specially designed for various types of bridge expansion joints. These seals use rubber’s airtightness and water expansion property to effectively prevent rainwater
Low-retraction anchorage is a kind of low-retraction and high-efficiency anchor specially developed for the short prestressed beam anchor, which has a large effective permanent prestress
The application of prestressing technology has greatly improved the bearing capacity and durability of bridges. According to the different sequences of prestressing tendons and beam
Rubber waterstop is a waterproof material used in construction, water conservancy, tunnels, underground projects, etc. It is usually made of synthetic rubber with good weather
Finger expansion joint is a bridge expansion joint device composed of finger steel plate (formerly referred to as ‘comb’ or ‘tooth’ plates), stainless steel sliding
The steel carbon content of prestressed steel wire is generally between 0.6% and 0.90%, which should meet the relevant national standards. The diameter of the
Prestressed concrete steel strands are used in a wide range of applications. It has relatively high texture strength and good plasticity, but it has a
Structure and function of the pot rubber bearing The pot rubber bearing uses the elastic rubber block in the semi-closed steel pelvis to realize the rotation of
Not all steel wires are prestressed concrect steel wires (PC wire), and prestressed steel wires are generally used in construction. PC wire is made of
The rubber bearing is made of multi-layer rubber plates embedded, bonded, and pressed with thin steel sheets, and the bearing capacity can reach 10000kN. It
Rubber bearings are widely used in construction projects. Its function is to bear the vibration load of operation vibration and extreme weather such as earthquake
Reinforced concrete beam bridges usually include simply supported beams (T-shaped beams, composite beams with less reinforced micro-bent plates, π-shaped beams and plate beams, etc.), cantilever
Prestressed plastic corrugated duct is a single-wall corrugated duct extruded from high-density polyethylene (HDPE), which is used for post-tensioned prestressed concrete structures and is a
