The Fourth Water Plant covers an area of 119 mu, with a design scale of 200000 tons/day, and 100000 tons/day for Phase I construction. The estimated investment of the water source project is 14.6 million yuan, including the top steel pipe with a diameter of 1.4 m wall, process pipe installation, electrical pipe laying and other projects. Water source project: water intake steel pipe jacking (diameter 1.4m, single length about 800m, wall thickness 14mm, 2 pieces), water intake head, immersed pipe, water intake pump room, process equipment pipeline installation, embedded parts (electrical process, pipeline anti-corrosion, etc.). The proposed site has undulating terrain. The pipeline axis extends from west to east to the water intake pump house at 871.81m. It crosses a dike, a paddy field, a village, a soil road, a pond, a ditch and a paddy field in the middle of the Yangtze River, 2.10m. The river bottom (ZK1 hole) orifice elevation is -8.76m, and the height difference is 20.23m. There is a pond distributed in the middle of the pipeline axis, about 21.00m in width, 4.53m in water surface elevation and 2.00m in water depth. Its geomorphic unit belongs to the Yangtze River floodplain.

According to the characteristics of the project, the foundation pit excavation is carried out in two steps. The first step is to excavate part of the soil layer above the ground of the foundation pit. It is proposed to use the method of manual excavation with bulldozers. The second step is to use manual excavation. The excavation should be carried out vertically in strict accordance with the set sidelines to ensure the width and thickness of the lime fly ash gravel cushion under the foundation.

Huangtulian Viaduct (K19+334.550 ～ K19+860.450) is 525.9m long. The upper structure is composed of 7 connected 3-span prestressed reinforced concrete continuous beams, and the lower structure is a bored pile foundation with double column piers. The Huangping East Road Monolithic Bridge spans the existing urban roads, with a starting and ending mileage of K20+196.81 ～ K20+275.91. The superstructure is composed of a three span prestressed reinforced concrete continuous beam, and the foundation adopts bored piles and double column piers. The retaining wall is set on the left side of the line, which is fabricated reinforced concrete cantilever shoulder retaining wall. The wall is 3.0m-4.50m high. Culvert includes two box culverts (aperture 1-1.0m), one circular culvert (aperture 1-1.5m), cantilever subgrade retaining wall 212.25m, prefabricated pipe joints for circular culvert, rubble masonry for side wall of box culvert, and cast-in-place reinforced concrete roof. The ground line includes subgrade and culvert works. The subgrade section of the line adopts a triangular road arch with an arch height of 0.2m and a bottom width equal to the width of the subgrade surface. Generally, the slope is taken as 1:1.5. A natural berm with a width of no less than 1.0m is set outside the toe of the embankment slope. The thickness of the surface layer of the subgrade bed is 0.5m, and the thickness of the bottom layer is 1.5m.
