<p>A method for preventing silt by injection and diversion involves laying an injection pipe network (3) underwater which is communicated with water supply facilities (1). The injection pipe network (3) comprises at least one main pipe (4) which is provided with injection holes (6) with an interval, and water column having certain pressure can be jetted through the injection holes (6). The injection pipe network (3) also comprises a manifold (14) and a discharge pipe (16) arranged in parallel with the manifold (14) which is communicated with water supply facilities (1) and with the parallel discharge pipe (16) through a plurality of branch pipes (15). The manifold (14) and the branch pipes (15) are all provided with injection holes (17), and water column having certain pressure can be jetted through the injection holes (17).</p> |
