技术领域Technical field

本申请属于无砟轨道技术领域，更具体地，涉及用于减振地段的含纵向连接结构的装配式无砟轨道结构及装配方法。The present application belongs to the technical field of ballastless track, and more specifically, relates to an assembled ballastless track structure containing a longitudinal connection structure for a vibration damping section and an assembly method.

背景技术Background technique

无砟轨道是指采用混凝土、沥青混合料等整体基础取代散粒碎石道床的轨道结构。无砟轨道与有砟轨道相比，避免了道砟飞溅，平顺性好，稳定性好，使用寿命长，耐久性好，维修工作少，正在越来越多地被应用。板式无砟轨道构造主要涉及轨道板、沥青砂浆或自密实混凝土充填层、底座或支承层等结构，其中底座或支承层采用混凝土结构，铺设于底座或支承层上的沥青砂浆或自密实混凝土充填层是无砟轨道结构调整和支承传力的结构层。Ballastless track refers to the track structure that uses concrete, asphalt mixture and other integral foundations to replace the loose gravel track bed. Compared with the ballasted track, the ballastless track avoids ballast splashing, has good smoothness, good stability, long service life, good durability, and less maintenance. It is being used more and more. The structure of slab ballastless track mainly involves track slabs, asphalt mortar or self-compacting concrete filling layer, base or supporting layer and other structures, wherein the base or supporting layer adopts concrete structure, and the asphalt mortar or self-compacting concrete filling laid on the base or supporting layer The layer is the structural layer for the adjustment of the ballastless track structure and the supporting force transmission.

目前，我国板式无砟轨道型式主要有CRTS Ⅰ型板式、CRTS Ⅱ型板式和CRTS Ⅲ型板式无砟轨道。CRTS Ⅰ型板式无砟轨道为单元板，板与板之间不纵连，不设横向挡块，铺设在现浇的具有凸型挡台的钢筋混凝土底座上，由凸型挡台限位。单元板式无砟轨道结构中，铺设安装后的每块轨道板之间是独立的，其不足之处是，在线路运行一段时间后，轨道板与沥青砂浆填充层会发生剥离，轨道板的纵向端部易产生翘曲，这无疑会给列车运行的平稳性、舒适性和轨道结构的寿命造成不利的影响。尽管目前存在相应的改进连接方式的方案，但是总体来看依然难以满足板体之间的受力变形以及制备工艺复杂问题，而且无法克服目前无砟轨道异形板过多导致整个无砟轨道的装配、维修难等问题。At present, my country's slab ballastless track types mainly include CRTS Ⅰ slab type, CRTS Ⅱ slab type and CRTS Ⅲ slab ballastless track. CRTS Ⅰ slab ballastless track is a unit slab, there is no longitudinal connection between the slab and the slab, and no transverse stop is provided. It is laid on the cast-in-place reinforced concrete base with convex stop, and the position is limited by the convex stop. In the unit slab ballastless track structure, each track slab after laying and installation is independent. The disadvantage is that after the line runs for a period of time, the track slab and the asphalt mortar filling layer will peel off, and the longitudinal direction of the track slab The ends are prone to warping, which will undoubtedly have an adverse effect on the smoothness and comfort of the train operation and the life of the track structure. Although there are corresponding solutions to improve the connection method, it is still difficult to meet the stress and deformation between the plates and the complicated preparation process, and it cannot overcome the current assembly of the entire ballastless track caused by too many special-shaped plates of the ballastless track. , Difficult maintenance and other issues.

CRTS Ⅱ型板式无砟轨道板其采用纵连式，无砟轨道板与板之间纵连，通过纵向精扎螺纹钢筋和张拉锁件形成纵连结构，设有横向挡块，可以克服CRTS Ⅰ型板式无砟轨道存在的部分缺陷。例如专利文献201695285U中公开的无砟轨道板纵向连接张拉锁，其通过从轨道板纵向伸出的钢筋进行连接锁紧实现纵向连接。但是这种连接型式基本等同于纵向预应力钢筋的方式，连接构造复杂，施工起来较为烦琐，而且此刚性连接在温度力过大的情况下，轨道板仍存在上拱的可能，这将对轨道结构的寿命和列车运行的平稳性、舒适性造成不利的影响。CRTS Ⅱ slab-type ballastless track slab adopts the longitudinal connection type. The ballastless track slab and the slab are connected longitudinally. The longitudinally connected structure is formed by longitudinally finely tying threaded steel bars and tension locks. It is equipped with horizontal stoppers to overcome CRTS Ⅰ Part of the defects in the slab-type ballastless track. For example, the longitudinal connection tension lock of the ballastless track plate disclosed in Patent Document 201695285U realizes the longitudinal connection by connecting and locking the steel bars longitudinally extending from the track plate. However, this connection type is basically equivalent to the way of longitudinal prestressed steel bars. The connection structure is complicated and the construction is cumbersome. Moreover, when the temperature force of this rigid connection is too high, the track slab may still be arched, which will affect the track. The longevity of the structure and the smoothness and comfort of train operation have an adverse effect.

专利文献CN204370701U中公开的一种用于装配式混凝土建筑结构中的钢筋机械连接装置，其通过将待连接钢筋端部镦粗加工，并在端部穿设钢筋套筒，利用连接套筒与连接螺栓实现钢筋的连接。但是这种连接方式构造复杂，施工起来较为繁琐，钢筋套筒上设置的卡环与待连接钢筋之间预留的间隙也会导致相邻的装配式轨枕板或轨道板不在同一平面，施工时精度难以控制。Patent document CN204370701U discloses a mechanical connection device for reinforcing steel bars in a prefabricated concrete building structure, which upsets the ends of the steel bars to be connected, and inserts a reinforcing steel sleeve at the end, and uses the connecting sleeve to connect Bolts realize the connection of steel bars. However, this connection method is complicated in structure and cumbersome to construct. The gap reserved between the retaining ring set on the reinforcing steel sleeve and the reinforcing steel bar to be connected will also cause the adjacent fabricated sleeper plates or track plates to be out of the same plane. The accuracy is difficult to control.
