河畔泵站站址的防护措施

Measures for protection of location site of river bank pumping station

格拉输油管道的沱沱河泵站靠近沱沱河边,由于沙土堤岸经不住洪水冲刷,泵站的安全受到威胁,为保护站址,必须对堤坝进行防护。采用毛石浆砌堤岸,在当地气候条件下易受冻害破坏;选择柔性的石笼堤坝,可抵抗冻胀,防止冲刷,是一种可靠的防护措施。介绍了石笼堤坝的作用和具体的设计及施工方法。

Tuotuo River Pumping Station on Gela Oil Transport Pipeline lies near the bank of Tuotuo River. As the sand soil bank couldn't stand with the scour of the flood, the safety of the pumping station was in danger. To protect the station site, bank protection had to be carried out. Rubble masonry dyke would be damaged by freeze under local climate condition; flexible rock crib dyke could stand with frost heave and scour, and it was a reliable protection measure. Introduced the role of the rock crib dyke, concrete design and construction method.
