River channel local riverbed and river channel riverbed undercutting control method
The invention relates to a riverway local riverbed and a riverway riverbed undercutting control method, and the riverway local riverbed undercutting control method comprises the steps: carrying out the full-section excavation at a river scour reach to be subjected to riverbed undercutting treatment, and then backfilling a material with the particle size larger than the anti-scour particle size when the undercutting control section generates the maximum flow speed, and backfilling to be consistent with the original riverbed elevation of the undercut control section of the riverbed. A riverbed undercut control section of a river channel is excavated and backfilled with a material larger than the anti-scouring particle size of the riverbed undercut control section, the riverbed is protected, the riverbed resistance is increased, the section becomes a blocking section of riverbed scouring undercut, and riverbed undercut can be effectively controlled or slowed down.
本发明涉及河道局部河床和河道河床下切控制方法,其中河道局部河床下切控制方法,在待进行河床下切治理的河流冲刷河段,进行全断面开挖,然后回填粒径大于该下切控制断面发生最大流速时的抗冲刷粒径的材料,回填至与河道河床下切控制断面原河床高程一致。对河道河床下切控制断面开挖并回填大于其抗冲刷粒径的材料,防护了河床,加大了河床阻力,使得该断面成为了河床冲刷下切的“阻隔断面”,可有效控制或减缓河床下切。
