建设内容：新建乐塘桥桥梁全长 28.64m，梁底高程 179.70m，该桥所在路段为一级公路。上部设置为 1×20m 预制预应力钢筋混凝土空心板桥梁，下部结构为桩基接盖梁埋置式桥台。桥梁全长 28.64m，桥宽 8.5m。全桥平面位于直线段，全桥行车道横坡为双向 2%，桥梁为跨越河流设置的桥梁，水流方向与路线前进方向正交，呈90°。

主要指标：

1、水土流失防治责任范围为0.14hm2，其中永久征地面积0.05hm2，临时占地面积0.08hm2；

2、土石方开挖773.12m3,回填量为1468m3,借方905.9m3，弃方211.02m3。

3、项目内不需要设置弃土场、弃渣场；

4、水土流失防治目标值达到：水土流失治理度100%，土壤流失控制比1.00,渣土防护率达到100%，表土保护率达到100%，无林草植被恢复率和林草覆盖率（未占用林、草地，无需恢复林、草地）；

5、水土保持投资8.59万元；

7、按时缴纳水土保持补偿费0.14万元。
