Description
Technical Field
The invention relates to a handheld dredging device, in particular to a handheld dredging device and a dredging method thereof, which are mainly suitable for large-size box culverts.
Background
The flow rate of sewage is reduced after the sewage flows into the drainage box culvert with a small gradient from the drainage box culvert with a large gradient, and sediment and suspended solids carried in the sewage are very easy to deposit in the box culvert with a small gradient and a large size; in addition, the flow and the flow rate of the sewage received by the box culvert in the dry season are far smaller than the value of the rainy season, so that large-particle suspended matters which can be taken away by the sewage in the rainy season are deposited in the dry season; at the same time, the possible physical and chemical reactions between the sediments can also cause solidification and hardening of the sludge, further deepening the thickness of the sludge. At present, large-size box culverts of a plurality of cities at home and abroad have the problem of sedimentation with different degrees, and if sedimentation pipelines are not cleaned in time, the health of residents and the normal operation of the cities can be influenced.
The existing dredging method for the box culvert at home and abroad mainly comprises a high-pressure water jet dredging method, a winch dredging method, a water flushing dredging method, a blocking flushing door dredging method and the like. The methods are designed for small-size box culverts basically, some technologies are not suitable for large-size box culverts, and some technologies have the limitations of high operation cost, insufficient dredging capability, secondary pollution, incapability of adapting to complex terrain conditions and the like when the large-size box culverts are operated. Taking the current and popular vehicle-mounted high-pressure water jet sludge removal method as an example, the high-pressure water jet prepared by the method is smaller in size relative to the large-size box culvert section, and the generated high-pressure water jet can not stir sediment in the whole section; the manufacturing cost and the running cost are very high, and the method is difficult to apply to common drainage pipeline enclosure enterprises; in the dredging process, a large amount of clean water is required to be consumed, the concept of sustainable development is not met, and the waste water generated by impact can overflow from an inspection well or flow back into a drainage branch pipe, so that secondary pollution is easily caused. At present, the dredging of part of urban box culverts in China still depends on manual cleaning, for example, tools such as spades, rubber rafts and the like are adopted for manual dredging, and the efficiency is quite low.
