Railway T-shaped beam integration super-high strength concrete-micro-porous ceramic compound sound barrier
The invention discloses a railway T-shaped beam integration super-high strength concrete-micro-porous ceramic compound sound barrier. The railway T-shaped beam integration super-high strength concrete-micro-porous ceramic compound sound barrier comprises a railway foundation cross beam and rib columns and a sound barrier body which are arranged on the railway foundation cross beam; the lower ends of the rib columns, the upper surface of the foundation cross beam and prefabricated blocking pieces outside the lower ends of the rib columns are mutually connected through embedded bars or bolts, and cast-in-place concrete fully covers and fixes the embedded bars or the bolts; anchoring steel plates and the embedded bars are embedded in the upper surface of the foundation cross beam, the lower ends of the rib columns are fixedly connected with the anchoring steel plates through the bolts, and the prefabricated blocking pieces are provided with the embedded bars and are in concretion connection with the embedded bars in the upper surface of the foundation cross beam. The railway T-shaped beam integration super-high strength concrete-micro-porous ceramic compound sound barrier adopts a structure that prefabricated element pieces are fixedly connected with the cast-in-place concrete on the spot, the building reliability of the element pieces is improved, the quality is guaranteed and stabilized, the efficiency of cast-in-place construction is higher than the efficiency of an existing welding technology, the concrete fully covers metal connecting pieces after casting is completed, the metal connecting pieces can be prevented from rusting and loosing, maintenance-free is achieved, and the stress of each structural piece is more reasonable.
