機場捷運車站電梯電扶梯設置環境界面探討 Investigating the Environment Interface of Elevators and Escalators in TIAA MRT Stations
A16站電扶梯。

機場捷運車站之電梯/電扶梯是旅客進出車站重要的載運設備,主要為協助行動不便者及大量旅客快速進出車站,因此在營運時將扮演十分重要的角色。其設置環境界面考量重點如下:
一、地理環境
機場捷運跨台北市、新北市及桃園市等3個行政轄區,台灣屬海島型氣候,夏季多颱風、冬季則有東北季風,高架車站易受潮及遇雨機坑容易進水。故設備的設置應考量開口及動線方向,以減少設備受環境氣候的影響。
二、建築型式及設備配置
機場捷運車站多屬高架車站,且採綠建築型式之規劃設計。高架車站以大面積開放通風型式設計,致外側設備易受風雨侵襲而受潮損壞及故障,目前雖已加強防風雨設施及截水溝,但在颱風及豪大雨的氣候下,尚難完全防止雨水進入。設備應考量採全覆蓋式或設置於內側,以減少受雨水侵襲而產生損壞及故障。
三、機坑排水方式
目前設備機坑的排水方式依機坑位處地面層或二樓層分為重力排水與非重力排水,重力排水不易有積水問題,平常只需注意排水口是否阻塞;非重力排水之機坑依可否由設備外目視觀察或既有預留結構又分自動排水泵浦或水位偵測加移動式泵浦兩種,自動排水泵浦平時需要檢查泵浦及浮球感應開關是否正常作動;水位偵測則需由站務員接獲水位警報後,攜帶移動式泵浦把水抽出機坑外,且需要電梯/電扶梯維修人員協助開啟乘場門或機坑蓋板。
四、機坑電氣插座設置
受雨水侵襲時,機坑內埋入式或側壁上之插座易受雨水侵襲產生保護開關跳脫,目前車站已加強防風雨改善,雨水應較不容易進入機坑,或於插座盒底部加設槽鋼,以避免雨水進入而發生故障跳脫。

The elevators and escalators in TIAA MRT stations are important transport equipment mainly to assist those with limited mobility and transport the large number of passengers quickly in and out of the station so they play very important roles in system operation. The evaluation key points of the environment interface of installing the equipment are as follows:
1.Geographical environment
The TIAA MRT crosses three jurisdictions including Taipei, New Taipei and Taoyuan City. Since Taiwan belongs in an island climate area where typhoons are frequent in summer and the northeast monsoon occurs in the winter, elevated stations are easily damp and unit pits may easily accumulate water during heavy rain. Therefore, installation of the equipment should consider building openings and route direction to reduce the impact from the environment and climate.
2.Building models and equipment configuration
The majority of TIAA MRT stations is elevated stations and adopted the green building model’s designs. Elevated stations are designed with large airy open spaces so equipment is susceptible to wind and rain causing moisture damage and malfunction. Although currently weatherproof facilities and intercepting drains are strengthened, it is still difficult to completely prevent rain from entering during typhoon weather and heavy rain. Equipment should consider full coverage or installing inside the station to reduce the damage and failure caused by the rain.
3.Drainage approach for unit pits
Currently, the drainage approach for unit pits of equipment is divided into gravity drainage and non-gravity drainage approaches according to whether the unit pit is on the ground floor or second floor. When using the gravity drainage approach, water accumulation does not occur often but the waterway needs to be regularly checked for blockage. As for the non-gravity drainage approach, there are the automatic drainage pump and water level detection with mobile pump according to whether the equipment can be observed externally or if it is reserved structure. When adopting the automatic drainage pump, the pump and float sensor switch should be regularly monitored; the water level detection with mobile pump requires an operator to utilize the mobile pump to extract water from the unit pit when the water level detection alarm rings. In addition, this protocol requires elevator/escalator maintenance staff to assist in opening the elevator door or unit pit cover.
4.Electrical outlet settings of unit pits
When affected by the rain, the pit sockets in the unit pit either on the side wall or embedded is likely to trip the protective switch. Currently, the station has enhanced wind and rain prevention measures so that rain should less likely enter the unit pit. In addition, channel steel can be installed at the bottom of the socket case to prevent rainwater from entering and triggering the failure switch.
