Construction method for limiting groove of ballastless track base plate of high-speed railway
The invention relates to the field of high-speed railway construction, and discloses a high-speed railway ballastless track base plate limiting groove construction method which comprises the steps that the surface of a limiting groove formwork is coated with a release agent; the limiting groove formwork is placed at a preset position in the base plate formwork, and the limiting groove formwork is supported and fixed through anchoring steel bars; a bottom plate of the limiting groove formwork is tightly jacked through jacking screws at the four corners of the limiting groove formwork; the two tie screws are implanted into the middles of the two sides of the bottom plate in the limiting groove formwork; the elevation adjusting device is used for correcting the elevation of the limiting groove formwork; pouring concrete to the base plate template; and dismantling the limiting groove template. The technical problem that in the prior art, the size of the limiting groove has the possibility of serious deviation after the formwork is disassembled is solved, the jacking screws and the tie screws are additionally arranged in the limiting groove formwork, deviation cannot occur in the pouring process, the supporting structure of the limiting groove formwork is reliable, and the rigidity of the formwork is high.
本申请涉及高速铁路施工的领域，并公开一种高速铁路无砟轨道底座板限位凹槽施工方法，包括：限位凹槽模板表面涂刷脱模剂；将限位凹槽模板放置于底座板模板中的预设位置，并利用锚固钢筋对限位凹槽模板进行支撑固定；利用限位凹槽模板中四个边角的顶紧螺杆对限位凹槽模板的底板进行顶紧；将两根拉结螺杆植入至限位凹槽模板中底板两侧的中部；利用高程调整装置对限位凹槽模板的高程进行校正；向底座板模板砼浇筑；限位凹槽模板的拆除。本申请解决了现有技术中模板拆模后限位凹槽尺寸有严重偏差的可能性的技术问题，实现了在限位凹槽模板中增加顶紧螺杆和拉结螺杆，浇筑过程中不会发生偏移，也使得限位凹槽模板的支撑结构可靠、模板刚度高。
