Abstract
The utility model relates to a foundation trench dredging device. The dredging device comprises a seamless steel pipe, scraper blades, lifting rings, a rubber tube and a cable; the seamless steel pipe with the diameter of 20 cm and the wall thickness of 2cm is welded and fixed into a rectangle, the short side of the rectangle is 4 m, the long side of the rectangle is 6 m, and 81 equidistant pinholes of 1 cm are downard formed on the short side of the rectangle; the rubber tube is connected to the short side of the rectangle, and the rubber tube is connected with an air compressor on a work boat; the middle parts of two long sides of the rectangle are welded into a whole by 5 scraper blades, thus the weight of the foundation trench dredging device is increased; 5 dredging devices are pulled to incline along the advance direction and are equidistantly welded on two long sides, and the lifting rings are fixed on the ends of the two long sides of the rectangle; and the cable is fixed in the lifting rings and is communicated with the work boat, solid rubbers are fixed on the lower parts of the two long sides of the rectangle, and directly slide on a footstone in the foundation trench. The dredging device provided by the utility model has the advantages of simple structure, safety, reliability, good dredging effect, low labor intensity and high efficiency.
Description
Technical field
The utility model relates to a kind of dredging device, particularly relates to a kind of foundation trench desilting device that can directly carry out desilting at foundation trench foundation stone end face.
Background technology
As everyone knows, large-scale hydraulic members such as foundation trench placement caisson are used, and need dig and spread the water-bed groove of filling out foundation stone (stone or rubble) in advance; Foundation trench is ready, and waiting for generally all has one section grade to put the time by large-scale hydraulic members such as laying caisson; Like this, the certain thickness mud scum that just possibly deposit above the foundation trench foundation stone is before large-scale hydraulic members such as caisson are laid; Must carry out manual operations by diver's diving, usually, implement spray towards desilting with giant; Operation intensity is big, and is dangerous high, and effect is low.
Summary of the invention:
The main purpose of the utility model is to overcome above deficiency and a kind of simple in structure, safe and reliable and foundation trench desilting device that can directly carry out desilting at foundation trench foundation stone end face is provided.
The utility model solves the technical scheme that its technical problem adopted: it comprises operation ship, dredging device, sebific duct and air compressor machine, it is characterized in that: described foundation trench desilting device comprises seamless steel pipe, scraper plate, suspension ring, sebific duct and hawser; The rectangle that the welding of described seamless steel pipe fixedly surrounds on the rectangular minor face, has equidistant aperture down, connects sebific duct on this minor face, and sebific duct is connected with air compressor machine on the operation ship; Relative inner face place, two long limits of rectangle is welded into one with the piece scraper plate, and the end on two long limits of rectangle is fixed with suspension ring, and the interior fixedly hawser of suspension ring also leads to operation ship always.
The utility model can also adopt following technical measures:
Drawn tilt and equidistant being welded on two long limits of direction of advance with the piece scraper plate towards the foundation trench desilting device in the middle of two long limits of described rectangle;
The bottom on two seamless steel pipes of described rectangle, 1 long limit is fixed with vulcanie.
Advantage and the good effect that the utlity model has are: can foundation trench foundation stone end face directly carry out desilting, simple in structure, safe and reliable, dredging effect is good, labour intensity is low and efficient is high.
Description of drawings
Fig. 1 is the utility model overall structure sketch map.
Among Fig. 1: 1. seamless steel pipe, 2. scraper plate, 3. suspension ring, 4. sebific duct,
5. hawser, 6. aperture, 7. vulcanie.
The specific embodiment
Be the summary of the invention characteristics that further to understand the utility model and effect following examples for example now, and conjunction with figs. specifies as follows, see also Fig. 1.
As shown in Figure 1: described foundation trench desilting device comprises seamless steel pipe 1, scraper plate 2, suspension ring 3, sebific duct 4 and hawser 5; Described diameter is that 20cm, wall thickness are the rectangle that seamless steel pipe 1 welding of 2cm fixedly surrounds; Rectangular minor face is 4m; Long limit is 6m, on the rectangular A minor face, has the aperture 6 of equidistant 81 1cm down; Connect sebific duct 4 on this A minor face, sebific duct 4 is connected with air compressor machine on the operation ship; Relative inner face place, two long limits of rectangle is welded into one with 5 scraper plates 2; It has increased the weight of foundation trench desilting device; 5 scraper plates 2 are drawn tilt and equidistant being welded on two long limits of direction of advance towards the foundation trench desilting device; The end on two long limits of rectangle is fixed with suspension ring 3, and suspension ring 3 interior fixedly hawsers 5 also lead to operation ship always, and the bottom on two long limits of rectangle is fixed with vulcanie 7.
During operation, the loop wheel machine on the operation ship passes through the suspension ring 3 on the seamless steel pipe 1, and the foundation trench desilting device is sling to be put in the foundation trench that digs in advance and be filled with foundation stone; Then, spur rectangle seamless steel pipe 1 forward, the bottom on two long limits of rectangle is fixed with vulcanie 7 and directly in foundation trench, slides on the foundation stone; To reduce the abrasion of steel pipe, can prolong the application life of seamless steel pipe 1, in addition; Equidistant 5 scraper plates 2 of inclination of welding in the middle of two long limits of rectangle, can be when spurring rectangle seamless steel pipe 1 forward with foundation trench on the foundation stone mud scoop up, meanwhile; Operation ship boat-carrying 31.2 ㎡/min air compressor machine (8.6bar) make 81 apertures 6 with 80m/s speed ejection pressure-air, like this through sebific duct 4; Blow while shoveling and will accumulate in very smoothly in the foundation trench that the mud come-up leaves on the foundation stone, general job ship speed of advancement is controlled at 3m/min, like this; Seabed unit area butene-1 copolymer ㎡) jet amount can reach 2.6m, generally has the thick mud of 2.0m all disposablely to dash to the greatest extent.
Its advantage is: can foundation trench foundation stone end face directly carry out desilting, simple in structure, safe and reliable, dredging effect is good, labour intensity is low and efficient is high.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection domain of the utility model claims.
