Problems solved by technology

There is a dense pile group structure under the high-piled wharf in the port. Under the influence of time factors, tides, wind and waves carrying mud, or wharf berthing upgrades, etc., it is necessary to clean up the silted soil and undisturbed soil under the wharf. Due to the narrow space, resulting in Some large and medium-sized mature dredging

Abstract

The invention provides a wharf bottom desilting machine. The wharf bottom desilting machine comprises sliding grooves, a supporting table, a hydraulic air cylinder, a motor, a desilting component anda high-pressure water pump, wherein the sliding grooves are formed in the edge of the wharf ground; the lower surface of the supporting table is provided with sliding rails matched with the sliding grooves, the supporting table is provided with a connecting part which protrudes from the edge of the wharf ground, and a through hole used for allowing a telescopic rod to pass through is formed in theconnecting part; the output end of the hydraulic air cylinder is connected to the telescopic rod; the motor is arranged at the tail end of the telescopic rod; the desilting component is connected tothe output end of the motor, and comprises a rod part and at least two stirring fins arranged at the head end of the rod part; and the high-pressure water pump is arranged on the connecting part and connected to the desilting component through a water pipe. The wharf bottom desilting machine provided by the invention has the advantage of being high in desilting efficiency. The invention further provides a desilting method of the wharf bottom desilting machine, a full-mechanical mode is adopted, only assistance and observation functions are achieved by labor, the desilting efficiency is high, potential safety hazards are low, and the quality is high.

Description

technical field [0001] The invention belongs to the field of wharves, and in particular relates to a dredging tool under the wharf and a dredging method thereof. Background technique [0002] With the rapid development of my country's port construction volume, a large number of new wharves and berths have been put into operation quickly. At the same time, due to the long-term siltation of the soil near the wharf, the safety performance of the wharf structure has been reduced. especially important. There is a dense pile group structure under the high-piled wharf in the port. Under the influence of time factors, tides, wind and waves carrying mud, or wharf berthing upgrades, etc., it is necessary to clean up the silted soil and undisturbed soil under the wharf. Due to the narrow space, resulting in Some large and medium-sized mature dredging equipment cannot operate. However, professional dredging equipment imported from abroad is expensive and has a low return on investment....
