Ballastless track railway deformation adjusting embankment structure and construction method thereof
The invention discloses a ballastless track railway deformation adjusting embankment structure and a construction method thereof. The structure comprises an adjustor fixing foundation, a bearing device and a deformation adjustor, the adjustor fixing foundation is used for being arranged on an embankment filling body, the deformation adjustor is fixedly arranged at the top of the adjustor fixing foundation, and the bearing device is arranged at the upper end of the deformation adjustor; and the deformation adjuster is used for driving the bearing device to ascend or descend. The construction method is used for constructing the embankment structure. When the unfavorable deformation amount generated by the railway foundation exceeds the ballastless track railway requirement, the bearing device is driven to ascend or descend upwards or downwards through the deformation adjustor, the height of the bearing device is adjusted, and the requirement of the ballastless track railway on vertical deformation is met, so that the treatment strength of the soil foundation can be reduced, foundation treatment engineering investment can be saved, or adverse effects caused by inaccurate foundation investigation can be avoided, and the problem that the soil foundation generates new uncertain and uneven settlement deformation due to underground water pumping or loading influences near a railway canbe solved.
本发明公开了一种无砟轨道铁路变形调节路堤结构及构造方法，该结构包括调节器固定基础、承载装置和变形调节器，调节器固定基础用于设置在路堤填筑体上，变形调节器固定设置在调节器固定基础的顶部，承载装置设置在变形调节器的上端；变形调节器用于带动承载装置上升或下降。该构造方法用于构造该路堤结构，当铁路地基产生的不利变形量超过无砟轨道铁路要求时，通过变形调节器向上或向下带动承载装置上升或下降，从而调整承载装置的高度，使其满足无砟轨道铁路对竖向变形的要求，从而可以减小土质地基的处理强度，故可以节省地基处理工程投资，或者避免地基勘察不精确带来的不利影响，还可以解决土质地基在抽取地下水或者在铁路附近加载影响产生新的不确定、不均匀沉降变形。
