Ballastless track sleeper cast-in-place mold and method
The invention discloses a ballastless track sleeper cast-in-place mold and method, relates to the technical field of track traffic, and solves the technical problem that at present, concrete at the connecting part of a sleeper and a roadbed slab main body is easy to crack and damage under the long-term train load effect, and then damage is easy to reform, the ballastless track sleeper cast-in-place mold comprises a shell, the shell is composed of a first square part, a second square part and two arc-shaped parts, the second square part and the two arc-shaped parts are all arranged above the first square part, and the two arc-shaped parts are symmetrically arranged on the two sides of the second square part respectively; square holes are formed in the two arc-shaped parts; the ballastless track sleeper cast-in-place die and the casting method thereof aim at adopting the ballastless track sleeper cast-in-place die to cast the whole sleeper structure and sleeper main body steel bars in place, the integrity of the sleeper and a main body roadbed slab is improved, and the ballastless track sleeper cast-in-place die and the casting method can be adopted to cast the sleeper which is good in durability, not prone to cracking and damage and good in apparent quality.
本发明公开了一种无砟轨道轨枕现浇模具以及方法，涉及轨道交通技术领域，解决了目前由于轨枕和道床板主体在长期的列车荷载作用下，连接部位的混凝土很容易开裂损坏，进而容易重新形成危害的技术问题，本发明包括壳体，所述壳体由第一方形部、第二方形部以及两个弧形部组成，所述第二方形部以及两个弧形部均设置于第一方形部的上方，两个所述弧形部分别对称设置于第二方形部的两侧；两个所述弧形部上均设置有方形孔洞；其目的在于，采用无砟轨道轨枕现浇模具，将整个轨枕结构和轨枕主体钢筋一起现浇混凝土，增加轨枕和主体道床板的整体性，并且采用该无砟轨道轨枕现浇模具和浇筑方法能够浇筑出耐久性好，不容易开裂损坏并且表观质量良好的轨枕。
