The invention discloses a channel desilting maintenance method, which comprises the following steps of: during desilting, raising silt deposited at the bottom of a riverbed by adopting an air blowing mode at a silt accumulation part at the bottom of the riverbed of a channel, so that the silt is taken away along water flow; a water turbine air-blowing device is adopted to convert water flow kinetic energy to achieve air blowing, and the water turbine air-blowing device is a fixed type water turbine air-blowing device and/or an automatic interval type water turbine air-blowing device. Air blowing is achieved through the air blowing desilting device. When the blowing head detects that the sludge is accumulated to a certain thickness, the water turbine air blowing device is started to supply air to the ventilation pipeline, and dredging is achieved; the situation that the blowing device is quickly abraded and loses stability due to the fact that the device works all the time is avoided, and particularly, abrasion of the inflating device is avoided, so that the service life can be long, the maintenance interval time of the device is greatly prolonged, channel dredging can be better achieved, the automation degree of the channel dredging device is improved, and manpower and material resource consumption is reduced. And the safety guarantee is better provided for the navigation channel.
本发明公开了一种航道清淤维护方法,清淤时,在航道河床底部淤泥堆积之处采用吹气的方式将河床底部淤积的泥沙扬起,使其顺水流被带走;采用水轮机鼓气装置转化水流动能实现吹气,所述水轮机鼓气装置为固定式水轮机鼓气装置和/或自动间隔式水轮机鼓气装置;吹气通过吹气清淤装置实现;当吹气头检测到淤泥堆积达到一定厚度后再启动水轮机鼓气装置为通气管道供气,实现清淤;避免了装置一直工作导致吹气装置很快磨损而失去稳定性,尤其是避免了打气装置的磨损,故可以获得长久的使用寿命,极大延长了设备的维护间隔时间,能够更好地实现航道清淤,提高其自动化程度并降低人力物力耗费,更好地为航道提供了安全保障。
