Seamless track laying method adopting middle locking and two-end stretching
The invention belongs to the technical field of seamless track line laying, discloses a seamless track line laying method adopting middle locking and two-end stretching, and aims to solve the technical problem that in the prior art, when a seamless track line is laid, a construction skylight is wasted in the construction process that stretching and locking can be carried out at a dragon tail only after a closure gap is welded and locked. The method comprises the steps that the unit rail section steel rail length of a steel rail is calculated according to the upsetting amount and reserved rail gaps, the steel rail is locked according to the unit rail section steel rail length, and at a closure gap, a welding machine is used for stretching and closing the reserved rail gaps; stretching and welding towards the closure gap direction by taking the upsetting amount as the stretching amount; and stretching towards the dragon tail at the dragon tail, and connecting with the existing steel rail through a clamping plate after stretching. According to the seamless track laying method, the length of the stretching amount is determined firstly, then the locking position is determined to lock the steel rail, stretching in the directions of the closure gap and the closure tail can be conducted after the steel rail is locked in the middle position, the construction efficiency can be improved to a great extent, and construction skylights are saved.
本发明属于无缝轨道线路铺设技术领域，公开了一种采用中间锁定两头拉伸的无缝线路铺设方法，以解决现有技术无缝线路铺设时，等待龙口处焊接完毕并锁定后才可在龙尾进行拉伸锁定的施工过程中浪费施工天窗的技术问题；该方法根据顶锻量和预留轨缝计算得出钢轨的单元轨节钢轨长度，并根据单元轨节长度锁定钢轨，在龙口处，使用焊机将预留轨缝拉伸合拢；再以顶锻量作为拉伸量向龙口方向拉伸焊接；在龙尾处，向龙尾方向拉伸，拉伸后通过夹板与既有钢轨连接。本发明提供的无缝线路铺设方法中先确定拉伸量的长度，再确定锁定位置锁定钢轨，在钢轨中间位置锁定后可以进行向龙口和龙尾方向的拉伸，可以很大程度的提高施工效率，节省施工天窗。
