Abstract

The utility model relates to a device for cleaning sludge of a long piled wharf bank slope, wherein a plurality of crescent-shaped steel plates 1 are equidistantly and vertically welded on a ventilation steel tube 2 and a water flow steel tube 3 which have the diameter of 100 mm and are parallel with each other, and both of the two steel tubes are drilled with small holes; High-pressure air and high-pressure water are conveyed to a sludge remover by flexible hoses 5, 6 of a waterborne vessel outside a wharf. The crescent-shaped steel plates 1 slump into the sludge, and the high-pressure water and the high-pressure air are sprayed from top to bottom toward the sludge, so that the sludge on the bank slope floats upward and flushes downward along the bank slope while slowly pulled downwards along an originally designed excavating surface of the bank slope in company with the crescent-shaped steel plates 1 of the sludge remover and sludge removing work is accomplished from top to bottom. The utility model has the advantage that no staff needs to be present under the wharf unless diving operation and formal operation while has the advantages of high safety, the efficiency which is six times the prior efficiency that the sludge is removed by a diver's diving and good quality of construction.

Description

Long piled wharf bank slope dredging device

Technical field:

The utility model relates to a kind of dredging device, particularly relates to a kind of long piled wharf bank slope dredging device that is used for port works and marine traffic engineering.

Background technology:

As everyone knows, the alluvial of long piled wharf offshore slope silt makes the bank slope steepening, forms harbour shelves post lateral thrust offward, threatens dock safety.For this reason, need frequent desilting, make offshore slope keep former design side slope.Construction operation under the long piled wharf, both be subjected to the restriction in space, be subjected to the influence of tidal level again, construction ship and machinery can't enter, and can only allow the diver dash with giant under water and become silted up, and threatening diver's personal safety at the incoming tide, simultaneously, manual work under water, efficient is low, poor stability, and can not guarantee the desilting quality.

Summary of the invention:

Main purpose of the present utility model is to overcome above deficiency and a kind of efficient height, safe and reliable, speed is fast, the desilting quality is high long piled wharf bank slope dredging device is provided.

The technical scheme that its technical problem that solves the utility model adopts is: it is made up of the ventilation steel pipe 2 of crescent shape steel plate 1, a  100mm,  100mm water flowing steel pipe 3, steel cable 4 and a flexible pipe 5,6, multi-disc crescent shape steel plate 1 equidistant vertical welding is on two  100mm ventilation steel pipe 2 and water flowing steel pipe 3 parallel to each other, be drilled with aperture respectively on ventilation steel pipe 2 and the water flowing steel pipe 3, two steel pipes are connected operation ship 7 by flexible pipe 5 respectively and fill high pressure gas and fill water under high pressure with 6.

The utility model can also adopt following technical measures: the pore that gets out spacing 5cm diameter 0.5cm on the described ventilation steel pipe; Get out the hole for water spraying of spacing 20cm diameter 1.6cm on the described water flowing steel pipe.

Advantage and the good effect that the utlity model has are: from top to bottom utilize the spray of water under high pressure and pressure-air to dash, with sluicing under the littoral aspect of mud on the bank slope, belong to non-diving operation, during formal operation under the harbour no personnel exist, have the efficient height, generally can improve 6 times and safety, advantage that construction quality is good.

Description of drawings:

Fig. 1 is the utility model working state schematic representation.

Fig. 2 is a long piled wharf bank slope dredging device structural representation.

Among Fig. 1, Fig. 2: 1. crescent shape steel plate, 2. ventilation steel pipe, 3. water flowing steel pipe, 4. steel cable, 5. flexible pipe, 6. flexible pipe, 7. ship, 8. pile.

The specific embodiment:

For further understanding summary of the invention characteristics of the present utility model and effect following examples for example now, and conjunction with figs. is described in detail as follows, and sees also Fig. 1, Fig. 2.

As shown in Figure 1: this long piled wharf bank slope dredging device, form by the ventilation steel pipe 2 of crescent shape steel plate 1, a  100mm,  100mm water flowing steel pipe 3, steel cable 4 and a flexible pipe 5,6, multi-disc crescent shape steel plate 1 equidistant vertical welding gets out a certain amount of pore of spacing 5cm diameter 0.5cm on the ventilation steel pipe 2 on two  100mm ventilation steel pipe 2 and water flowing steel pipe 3 parallel to each other; Get out a certain amount of hole for water spraying of spacing 20cm diameter 1.6cm on another root water flowing steel pipe 3, carry high pressure gas and water under high pressure by flexible pipe 5,6 to dredging device by the outer water surface ship 7 of harbour.At first, be absorbed in the multi-disc crescent shape steel plate 1 on the dredging device in the mud and reach the stiff mud face of former design excavation, then, from top to bottom spray is dashed water under high pressure with q.s and pressure and pressure-air in mud, make the mud come-up on the bank slope, and sluicing under the littoral aspect of energy, crescent shape steel plate 1 on this dredging device has certain operation width (generally pressing long piled wharf pilespacing design width), and can outside harbour, at the uniform velocity be pulled, along with facing down, the 1 littoral sloping former design excavation of crescent shape steel plate on the dredging device slowly affected, from top to bottom finished the desilting work of bank slope, eliminated the pressure of mud harbour pile 8.

Its advantage is: from top to bottom utilize the spray of water under high pressure and pressure-air to dash, with sluicing under the littoral aspect of mud on the bank slope, belong to non-diving operation, during formal operation under the harbour no personnel exist, safe and reliable, the efficient height, the diver needs 3 could finish a framework that 7m is wide clearly round the clock for every group, and one every group of this dredging device gets final product the wide framework (taking advantage of two Lower Low Waters) of two 7m of desilting round the clock, and efficient is that original diver's dive is dashed 6 times that become silted up, and construction quality is good.
