7. What is the basis for selecting the site of drainage pump station
7.排水泵站站址的选择依据什么？
(1) the site should be selected at the lower part of the drainage area, which is suitable for natural confluence. Attention should be paid to making full use of the original drainage system, so as to reduce the earthwork and occupation area of the channel excavation.But should pay attention to when using original canal canal system adjustment to the influence of the pumping station in the future, site near the drainage area, as far as possible to shorten the length of the outlet channel (2) the site should fall outside the lower river area (i.e., is located in the downstream of the river), in order to reduce the discharge head, reduce the installed capacity and power consumption (3) the site should fall in the river straight, riverbed stability, less scour deposition of concave bank of the river or curved reach;Width should be Y on the bund, to facilitate the construction of the cofferdam and quantity field decorate, but unfavorable also wide, as much as possible so as not to drain is too long to meet the requirements of the feed water and drainage positive positive (4), we must give full consideration to the conditions, as far as possible make the drainage pump and suction drainage pumps (5) pay attention to the combination of comprehensive utilization, pay attention to the vision and the recent combination for irrigation requirement, should consider to irrigating gate irrigation and irrigation irrigation system of elevation and arrangement, as far as possible to combine irrigation and drainage,(6) the site should be selected in a place with good geological conditions, avoiding the soft soil and fine sand stratum of silt as far as possible, and avoiding the waste river, water pool, deep ditch and other places prone to deposition

在建设排水泵站选择站址应注意以下几点。
(1)站址应选在排水区的较低处，与自然汇流相适应。耍注意充分利用原有的排水系统，以减少渠道开挖的土方工程和占地面积，
但在利用原有渠系时要注意将来渠系调整对泵站的影响，站址要尽量靠近容泄区，以缩短泄水渠的长度。

(2)站址应选在外河水位较低的地段（即设在外河下游处），以降低排水扬程，减少装机容量和电能消耗。
(3)站址应选在河流顺直，河床稳定，冲刷、淤积较少的河段或弯曲河段的凹岸；应有Y定的外滩宽度，以利于施工围堰和工料场的布置，
但也不宜宽，以免排水渠太长。尽可能满足正面进水和正面泄水的要求。
(4)要充分考虑自排条件，尽可能使自排水泵与抽排水泵相结合。    
(5)要注意综合利用，注意远景和近期结合。如有灌溉要求，则应考虑灌溉引水口和灌溉渠首的高程和布置，尽可能做到排灌结合，
提高设备利用率，扩大工程效益。
(6)站址应选在地质条件较好的地方，尽可能避开淤泥软土和粉细砂地层，避开废河道、水潭、深沟等易淤积的地方。
