Self-compacting concrete pouring device under ballastless track plate of high-speed railway bridge
The invention discloses a self-compacting concrete pouring device under a ballastless track plate of a high-speed railway bridge. The self-compacting concrete pouring device comprises a foundation, a base plate is arranged on the foundation, the ballastless track plate is arranged above the base plate, and a gap is formed between the base plate and the ballastless track plate; square-frame-shaped fixed formworks are arranged on the periphery of the ballastless track plate; movable templates are inserted into the left side and the right side of the fixed template; a control device is arranged on the base plate and used for temporarily limiting the movable template; the ballastless track plate comprises a pouring hole formed in the middle and observation holes formed in the two sides of the ballastless track plate, and vertical cylinders are arranged in the pouring hole and the observation holes. A vertical cylinder of the pouring hole is communicated with an overflow pipe, and an induction trigger device is arranged on the overflow pipe; when the self-compacting concrete poured into the vertical cylinder overflows into the overflow pipe, the induction triggering device induces and triggers the control device to release the movable formwork, the movable formwork moves in the direction away from the vertical cylinder under the pressure of the self-compacting concrete, and the problem that the self-compacting concrete pouring effect at the high-speed railway turning position is poor is solved.
本发明公开了一种高速铁路桥梁无砟轨道板下自密实混凝土灌筑装置，包括地基，地基上有底座板，底座板上方有无砟轨道板，底座板与无砟轨道板之间有间隔；无砟轨道板四周设有方框形的固定模板；固定模板左右两侧插装有移动模板；底座板上设有控制装置，控制装置对移动模板进行暂时限位；无砟轨道板包括有置于中间的灌筑孔和至于其两侧的观察孔，灌筑孔和观察孔内均设有竖筒；灌筑孔的竖筒上连通有溢流管，溢流管上有感应触发装置；灌注于竖筒内的自密实混凝土溢流至溢流管内时，感应触发装置感应到并触发控制装置释放移动模板，移动模板在自密实混凝土的压力下向远离竖筒方向移动，该发明解决高速铁路转弯处自密实混凝土灌筑效果不好的问题。
