Description
Technical field
The present invention relates to one soft foundation compacting mud by explosion technology under water, particularly relate to a kind of buried compacting mud by explosion device.
Background technology
Along with the development in city, precious land resources is day by day poor, fills out lake make ground engineering so people just constantly carry out filling out sea.Build in ground engineering filling out sea, maximum difficulty is how soft soil foundation, and the common process means at present for soft foundation mainly contain machinery row silt cushion, quick-fried rammer sludge extruding method and toe-shooting method three kinds;
Machinery row silt cushion, the mud on soft foundation is first excavated with desilting ships such as dredge boats by the method, then changes and inserts the higher rubble of intensity; The method Problems existing is: because the mobility of underwater sludge is comparatively large, intensity is extremely low, when desilting, a large amount of mud again can along with current backflow at once, cause foundation ditch to be shaped slowly, efficiency of construction is very low, is only applicable to the less shoal embankment of silt depth comparatively;
Quick-fried rammer sludge extruding method, the method is not removed mud, block stone of directly jettisoninging in mud, and then carry out the process of quick-fried rammer at jackstone end face, the pressure utilizing blast to produce causes block stone to sink, to reach the object squeezing weak soil mud; The method Problems existing is: the crowded silt degree of depth that single blast produces only has 2 ~ 4m, unit area needs frequently repeatedly to explode and just can reach construction requirement, not only explosive consumption is huge, and serious to the environmental destruction in waters, is not suitable for promoting on a large scale;
Toe-shooting method, No. ZL03119314.5, in No. ZL97125894.5 and ZL201110070978.1 Chinese patent, this technology is described in detail, its cardinal principle group's cartridge bag is laid in throwing dike head bottom certain depth, the cavity utilizing blast to produce causes throwing rubble to slip in cavity under Gravitative Loads, the effect of becoming silted up is squeezed to reach displacement, relative first two method, the method has convenient and quick construction, the advantages such as remarkable in economical benefits, be widely used in coastal treatment of soft foundation at present, but the same Shortcomings part of the method: such as longitudinally railway embankment using time, dike head mud is being subject to easily piling up protuberance at dike head under the exclusion of throwing rubble and Blast Loads, the further throwing of impact and obstruction embankment, cartridge bag can to surrounding transmission at explosion time energy, and can backfill rapidly at cavity by explosion upper area mud, reduce the spatial volume that effectively explodes, changing this situation of angle is the equal of waste a part of explosion energy, causes replacement depth not enough, can not insert in cavity by explosion in time because cartridge bag is placed on dike head outer rim enforcement explosion time top rubble, before will causing dike, mud be back in cavity, reduces to change and fills out effect.
Summary of the invention
For the problem in background technology, the present invention proposes a kind of buried compacting mud by explosion device, its innovation is: described buried compacting mud by explosion device by taking over a business, multiple footing, many dredging tubes, the blasting charge and suction dredges form; Described take over a business lower surface in the middle part of be provided with spherical groove, the blasting charge is arranged at the middle part of spherical groove bottom land; Multiple footing is arranged on the lower surface of taking over a business, and multiple footing is positioned at spherical groove periphery; Be provided with the multiple mud-suction holes being communicated with bottom spherical groove and taking over a business upper surface in taking over a business, the aperture of taking over a business upper end surface mud-suction hole forms mud mouth, and the aperture of spherical groove bottom land place mud-suction hole is formed into mud hole; Enter mud hole and be positioned at blasting charge periphery; One end of many dredging tubes is connected correspondingly with multiple mud mouth, and the other end of many dredging tubes is connected with suction dredge.
Principle of the present invention is: during construction operation, prefabricated buried compacting mud by explosion device is lifted on the soft foundation in operating area, start suction dredge, make the mud scum of surrounding by mud-suction hole and dredging tube by outside sucking-off, along with the sucking-off of mud scum, buried compacting mud by explosion device can sink gradually under the effect of self gravitation, after buried compacting mud by explosion device no longer sinks, stop inhaling mud operation, and remove suspender and dredging tube, then above buried compacting mud by explosion device, throwing operation is carried out, stone is thrown into above buried compacting mud by explosion device, after throwing amount reaches design height, wireless detonation way is adopted to be ignited by the blasting charge, after blast, cavity by explosion will be formed below buried compacting mud by explosion device, stone and buried compacting mud by explosion device together will to fall in cavity and to form ground, the invention has the advantages that: the design of mud-suction hole makes the mud scum below buried compacting mud by explosion device to be sucked out, the mud of very thickness is only had below buried compacting mud by explosion device, the mobility of the mud of these thickness is relatively poor, not easily reflux after blast, cavity by explosion can maintain the longer time, is conducive to stone and clogs cavity by explosion more fully, in addition, before blast, owing to having piled up a large amount of stone above buried compacting mud by explosion device, explosion energy can only have been released in the mud of surrounding and below, and explosion energy not only can be made to obtain more effectively utilizing, and in explosion energy is closed in, less to the eco-environmental impact of water proximate, required explosive charge is also relatively less, compared to existing method, under identical explosive charge condition, adopt the removing silt for replacement better effects if after apparatus of the present invention, footing on buried compacting mud by explosion device can insert in the mud layer of below dearly, is conducive to the supporting capacity improving ground further, explosion energy can lead below buried compacting mud by explosion device by spherical groove better, improves the utilization rate of explosion energy.
Preferably, take over a business described on upper surface and be provided with multiple hook.Hook is used for being extension hanger rope, is convenient to carry out lifting job to buried compacting mud by explosion device.
Preferably, take over a business described on upper surface and be provided with multiple anti-slop serrations.Anti-slop serrations can increase the angle of friction between buried compacting mud by explosion device and top stone, increases the anti-shear ability of ground, especially at versant, more can embody the effect of anti-slop serrations.
Preferably, multiple enter mud hole globally groove circumference be uniformly distributed.
Preferably, the end face of taking over a business described in is rectangle.
Preferably, described anti-slop serrations is square column type.
Advantageous Effects of the present invention is: effectively can reduce explosive consumption, and crowded silt is changed and filled out effect very well, to environmental destruction is less around.
