The invention discloses an urban rail transit turnout switch machine foundation pit drainage system, and the system comprises at least one switch machine foundation pit; at least one plash is arranged between the switch machine foundation pits, the plash is connected with the switch machine foundation pits through drainage channels, and the elevation of the plash is lower than that of the switch machine foundation pits; the switch machine foundation pit is provided with a waterproof mold, the mold is provided with an anchor bolt structure connected with the foundation, the edge of the mold is higher than the ballast bed surface, and the contact between signal switch machine equipment and accumulated water is isolated; a drainage vehicle is arranged on the water collecting pit, a plurality of hanging cups are rotatably arranged on the drainage vehicle, and the height position of the hanging cups rotating to the lowest position is lower than the water level elevation of the water collecting pit; and a water guide groove is formed below the position where the hanging cup rotates to the position above the water collecting pit and is in the horizontal direction. According to the invention, the switch machine system can be effectively isolated, the damage of accumulated water to the switch machine equipment is prevented, and the maintenance workload of the foundation pit of the switch machine is greatly reduced.
本发明一种城市轨道交通道岔转辙机基坑排水系统,包括至少一个转辙机基坑,所述转辙机基坑之间设置至少一个积水坑,所述积水坑与转辙机基坑之间通过排水通道连接,所述积水坑标高低于转辙机基坑;所述转辙机基坑设置防水模具,模具设有与基础联结的锚栓结构,模具边缘高出道床面,并隔绝信号转辙机设备与积水的接触;所述积水坑上设置排水车,所述排水车上可旋转设有若干挂杯,所述挂杯旋转至最低位置时的高度位置低于所述积水坑的水面标高;所述挂杯旋转至积水坑上方并呈水平方向时所在的位置的下方设有导水槽。本发明能够有效隔离转辙机系统,防止积水对转辙机设备的损害,并大大减少对转辙机基坑维护的工作量。
