Adjustable trapezoidal sleeper for easement curve ultrahigh downslope and construction method thereof
The invention discloses an adjustable trapezoid sleeper for easement curve ultrahigh downhill and a construction method thereof, the trapezoid sleeper is mainly suitable for construction of a trapezoid sleeper in a subway easement curve section, and the trapezoid sleeper is mainly composed of a prestressed concrete longitudinal beam, a square sleeve, a round sleeve, a connecting square pipe, a connecting round pipe, a height adjusting base plate and the like. According to the method, a square sleeve, a round sleeve and a prestressed concrete longitudinal beam are poured into a whole, then a height adjusting base plate of the needed specification is prepared according to an easement curve section fastener ultrahigh adjusting table, and then the easement curve ultrahigh down-slope trapezoidal sleeper is assembled on a construction site. The connecting square pipes and the heightening base plates are placed in the square sleeves on the two sides of the trapezoidal sleepers, the connecting round pipes are placed in the round sleeves in the middles of the trapezoidal sleepers, the check bolts are screwed down after the size positions are adjusted, and then the fasteners, the steel rails and other parts are assembled on the trapezoidal sleepers. And finally, assembling the four trapezoidal sleepers into a whole track panel and lowering the whole track panel to an easement curve section.
本发明公开了一种用于缓和曲线超高顺坡可调式梯形轨枕及其施工方法，该梯形轨枕主要适用于地铁缓和曲线地段梯形轨枕的施工，该梯形轨枕主要由预应力混凝土纵梁、方形套管、圆形套管、连接方管、连接圆管及调高垫板等部件组成。该方法中，先将方形套管、圆形套管与预应力混凝土纵梁浇筑为一体，然后根据缓和曲线地段扣件超高调整表，准备好所需规格的调高垫板，接着在施工场地对缓和曲线超高顺坡梯形轨枕进行组装，将连接方管和调高垫板放于梯形轨枕两侧的方形套管内，将连接圆管放于梯形轨枕中间的圆形套管内，调整好尺寸位置后拧紧防松螺栓，再将扣件、钢轨等零部件组装于梯形轨枕上，最后将四块梯形轨枕组装为一个整轨排下放到缓和曲线地段。
