Ballastless track lifting method and settlement adjusting method
The invention provides a ballastless track lifting method and a settlement adjusting method.The ballastless track lifting method comprises the following steps that firstly, measuring points are marked, the plane and the elevation of a track are measured, and the lifting amount is determined according to the measuring result; 2, drilling is conducted; 3, after the lifting amount is rechecked, a grouting pipe is installed; 4, lifting is started from the position with the maximum lifting amount, and lifting is conducted in a unit multi-time lifting method; 5, judging whether the lifting amount reaches a design position or not, if the lifting amount reaches the design position, executing the step 6, and if the lifting amount does not reach the design position, returning to the step 2; step 6, grouting and filling; and 7, the grouting holes are blocked, and a sealing layer is repaired. According to the ballastless track lifting method, the ballastless track is lifted from the position with the maximum lifting amount and is lifted by multiple times in units, it can be guaranteed that the numerical value of the lifting amount is accurate, the grouting amount is obtained through the lifting amount, and the gentle degree of the ballastless track obtained after lifting is further improved.
本发明提供一种无碴轨道抬升方法及沉降调整方法，该无碴轨道抬升方法包括以下步骤：步骤1：标识测量点，对轨道平面和高程进行测量，根据测量结果确定抬升量；步骤2：钻孔；步骤3：抬升量复核后安装注浆管；步骤4：从抬升量最大的位置开始抬升，分单元多次的抬升方法进行抬升；步骤5：判断抬升量是否达到设计位置，如果达到设计位置则进行步骤6，如果没有达到设计位置，则返回步骤2；步骤6：注浆填充；步骤7：注浆孔封堵，封闭层修复。本发明所述的无碴轨道抬升方法，以从抬升量最大的位置抬升，并分单元多次抬升的方法进行抬升，不仅能够保证抬升量的数值准确，通过抬升量获得注浆量，还提高了抬升后的无碴轨道的平缓度。
