The invention, which relates to the technical field of rail paving, discloses a construction method of a durable tramcar rail side paving structure. The method comprises the following steps: fixing aprefabricated pipe on a vibration damping block; enabling the lower end of the prefabricated pipe to transversely penetrate the damping block and enabling the lower end opening of the prefabricated pipe to be located in the side wall, facing the rail, of the damping block; pouring concrete into a foundation pit, and forming a concrete layer after concrete solidification; forming a sealing groove in the upper portion of the damping block; injecting a sealant into the upper end of the prefabricated pipe in a pressurized mode, enabling the sealant to enter a gap beside the damping block through the prefabricated pipe and then overflow upwards into the sealing groove; and after sealant solidification, forming a sealant layer in the sealing groove by the sealant. According to the construction method, the sealant is injected between the damping blocks (namely between semi-flexible transition layers) in a pressurized mode, the gap beside the damping block is not prone to expanding, so that the rail has long-time stability; and because of the combination of the first damping block and the second damping block, the good vibration reduction performance and high structural strength are realized.
本发明公开了一种耐久型有轨电车轨侧铺装结构的施工方法，涉及轨道铺设技术领域，其技术方案要点是：包括以下步骤：在减振块上固定预制管；预制管的下端沿横向穿过减振块，预制管的下端端口位于减振块朝向铁轨的侧壁处；在基坑内浇筑混凝土，混凝土凝固后形成混凝土层；在减振块上方制造密封槽；在预制管的上端加压注入密封胶，密封胶通过预制管进入减振块旁的缝隙，密封胶进而向上溢入密封槽内；待密封胶凝固后，密封胶在密封槽内形成密封胶层。本施工方法通过在减振块间（即半柔性过渡层间）加压注入密封胶，减振块旁的缝隙不易扩大，保证铁轨具有长时间的稳固性；减振块一与减振块二的组合兼具较好的减振性能和结构强度。
