As shown in the figure, ground explosive treatment explosive-feeding processing device of the present utility model comprises the tubular explosive loader 14 of a hollow, this explosive loader lower ending opening and the separable conehead 18 that is rigidly connected, the upper end of explosive loader 14 is connecting at least one joint connecting rod 10, the upper end of this connecting rod 10 is equipped with guide rod 5, on this guide rod 5 load dish 6 is housed, on load dish 6, be equipped with and drop hammer 4 along what guide rod slided, this drops hammer and is connected on the hoist engine 7 through a pulley 1 by a flexible rope 3, and described pulley is bearing on the workbench 8 by support 2.
Described conehead 18 can be pyramid or circular cone, also can be other structure that meets the utility model purpose.
Has the bindiny mechanism that both is interconnected and can controlledly separate on described explosive loader 14 and the conehead 18.
Described bindiny mechanism comprises and breaks away from pin and be fixedly installed in pin ear 15 on the explosive loader, has on the conehead 18 can pass described pin ear and by breaking away from the connecting lines that pin 16 pins, and breaks away from pin and separates backguy and link to each other.
Described bindiny mechanism also can be a kind of hydraulic mechanism, by being connected and disengaging of hydraulic mechanism control explosive loader and conehead.
Has alignment pin 17 between explosive loader 14 and the conehead 18, to prevent that horizontal moving taken place therebetween.
The maximum cross section of best described conehead 18 is greater than the cross section of the explosive loader 14 at coupled place, so that conehead 18 is easy to break away from when unclamping above-mentioned bindiny mechanism and mentioning explosive loader 14, the cartridge bag in the explosive loader fallen.
The top of explosive loader 14 has primacord hole 13, so that therefrom draw primacord.
Mud or layer of sand cut off primacord in order to prevent to mention explosive loader 14, and preferably explosive loader has raised structures at least above near described primacord hole 13.
Described raised structures can be to be produced by a protection ring 12 that is installed on the explosive loader.
Described conehead be steel construction or cement structures, also can be other structure that meets the utility model purpose.
On workbench 8, can have the protection backguy 9 that is connected with described connecting rod 10, to prevent rocking of connecting rod.
The utility model device also comprises the power set that are connected with hoist engine 7, and has two groups of " people " font supports 2, and its lectotype selection and steel wire rope model are according to the weight decision of dropping hammer.Guide rod length main with support height and consideration personnel load and unload convenient relevant, the heavy G formula G of the hammer that drops hammer 〉=s ε q
μ/ h determines, ε is the maximal destruction deformation values of layer of sand under the shock loading in the soil layer in the formula, gets greater than 10
-2, s is an explosive loader head maximum area, q
μBe sand dynamic load ultimate strength maximum in the soil layer, h is the height that drops hammer and.Movably the rope 3 of control link 10 is drawn on platform by personnel, with auxiliary connecting rod balance when impacting.Thin arm cartridge type explosive loader 14 has protection ring 12, and the protection primacord is not cut by the primacord hole 13 of explosive loader head when explosive loader 14 hangs down and proposes.Break away from the pin 16 and the outside of symmetrical pin ear 15 at the explosive loader arm.The alignment pin 17 that preferably has three distributions triangular in shape on the conehead 18.
The utility model can be handled the ground with following main feature: the layer of sand skewness, thickness is from tens centimetres to several meters, soil or the bearing capacity lower sand compound with mud matter, wherein layer of sand has certain bearing capacity in the composite earth, but thicker silt soil strata has characteristics such as high-moisture, macroporsity, low-intensity, high-compressibility, and this class soil can not satisfy the stability and the settlement request of structures as ground.In addition, the utility model can also be used for the explosive treatment powder charge of land sand foundation.
The utility model is according to the impact dynamic load intensity of the layer of sand kinetic theory much smaller than the soil of static load ultimate strength, the energy of power is converted into the potential energy that drops hammer by the hoist engine rope, dropping hammer freely falls through guide rod, and its potential energy passes to the explosive loader head by the load dish through connecting rod and is converted into impact energy; Soil layer under the effect repeatedly of cone head part shock loading by punching shear failure constantly, when explosive loader is driven into certain projected depth, out of stock rope separates explosive loader with its head, under the effect of the lateral resistance of soil, the explosive loader head is stayed in projected depth with pre-cartridging that it links to each other; When explosive loader is mentioned, form the plastic detonating cord or the plastic detonating tube of detonation train and draw thereupon, link to each other with front powder charge lead-out wire, all be linked to be an initiation net until designing powder charge.
The transmission of the utility model dynamic load energy adopts hoist engine to drop hammer by nonrigid cable traction, and boat-carrying kinetoplast and the mode that connecting rod separates with explosive loader have guaranteed the normal charge under hull waves, and can adapt to the powder charge construction under deep water and the billow condition; Utilize the impact dynamic load characteristic of soil, make all kinds of layers of sand destructions or indivedual rubble be crashed to pieces, squeeze and open, guaranteed shot depth than high-bearing capacity; The utility model is that pore-forming and powder charge are synchronous, has avoided collapse hole influence of layer of sand, has also reduced the activity duration; Non-electrical environment construction, job safety; The utility model charge device is simple, light weight, and required ship type is little, and investment cost is low.
Above-mentioned description with reference to drawings and Examples is just illustrative, and does not constitute qualification of the present utility model.Obviously, on basis of the present utility model, can make many modification, but not break away from its essence.
