Integral ultra-high strength concrete-micro-porous ceramic composite sound barrier of high-speed railway box beam
The invention discloses an integral ultra-high strength concrete-micro-porous ceramic composite sound barrier of a high-speed railway box beam. The integral ultra-high strength concrete-micro-porous ceramic composite sound barrier of the high-speed railway box beam comprises supporting rib columns continuously arranged at intervals along a railway line; between every two supporting rib columns, one side of the vehicle travelling surface of the railway is a sound adsorption plate, and one side of the back surface of the railway is a back plate; the lower end of each supporting rib column is provided with a rib column embedded part which is connected with a railway bridge embedded part, and the embedded parts are completely covered and solidified on the basis of cast-in-place concrete; the back plate and the supporting rib columns are connected and fixed by bolts, bolt holes are filled and covered with water-proof materials, and the sound adsorption plate and the back plate are fixed by connecting pins and by coating adhesives. According to the integral ultra-high strength concrete-micro-porous ceramic composite sound barrier, a microporous ceramic composite plate of a three-dimensional reticular hole structure is adopted to serve as the sound adsorption plate to meet the performance requirements of sound adsorption and noise reduction, the surface of the three-dimensional reticular hole structure is provided with W-shaped wedges, the rear cavity of the sound adsorption plate which is separated but communicated can be used for enhancing an sound adsorption and sound insulation effect, integral strength is increased by the horizontal rib of the back plate, the design of each water discharge structure can be used for meeting the intensity requirement of a sound barrier and draining in time, and therefore, the weather resistance of the sound barrier is better.
