1 Overview The Grand Canal of Huai’an to Jiangdu section, formerly known as the Canal, a total length of 128km, the first cut in 468 BC. After the new China was completed, the two sides of the Taiwan Strait carried out a large-scale embankment dike and the removal of the Zhongli Project, making it one of the key waterways for comprehensive utilization of irrigation, flood control and shipping in our province. The status quo of the Rim Canal is that the embankment elevation of both banks is 11.5 ~ 12.0m, the width of embankment is 6 ~ 12m, the width of river bottom is 50 ~ 70m and the elevation of river bottom is about 2m, which basically meets the standard of secondary channel and the water delivery capacity reaches more than 400 m ~ 3 / s. Huai River flows into the reach of this section via Shazhuang Power Station. The river flows into the present section through pumping stations 1, 2, 3 and 4 from Jiangdu and goes northward through Shazhuang Drainage Gate and Huai’an Pumping Station. The embankment of this section has direct water diversion gate hole 26; West embankment gate hole 7
