Abstract
An energy-storing medicine bag for underwater explosion and sludge squeezing is composed of ordinary concentrated medicine bag, enclosed air chamber, counterweight bag and water-proof jacket. The medicine bag has simple structure, easy processing and low additional cost. The method is suitable for underwater explosion silt squeezing engineering, can improve the utilization rate of explosion energy and the effect of explosion silt squeezing, and has the effect of reducing the explosion seismic effect.
Description
The utility model relates to a kind of underwater explosion expelling sludge cartridge bag, it is applicable to that underwater explosion squeezes silt engineering, the particularly sea wall compacting mud by explosion engineering of rockfilling.
In the compacting mud by explosion engineering, the blasting charge commonly used is a kind of common point charge (seeing the prosperous work of Yang Guang, underwater demolition engineering, Maritime Press's publication,, Beijing in 1992) under water.The weighing apparatus pressure of hammer wave of this cartridge bag underwater explosion is decayed comparatively fast in time, and action time is shorter, and the utilization of blast energy is restricted, so influence the further raising of compacting mud by explosion effect.
The purpose of this utility model provides a kind of energy storage cartridge bag that underwater explosion squeeze to be become silted up that carries out, to prolong cartridge bag blast pressure action time, improve blast can utilization rate, improve the effect of compacting mud by explosion.
The technical solution of the utility model is: set up a sealed gas chamber (4) on the top of common point charge (1), in point charge (1) bottom counter balance pocket (5) has been set, with water-proof jacket (6) whole energy storage cartridge bag has been fused, made it to be in closed state.
Primary structure of the present utility model as shown in Figure 1.Description of drawings: 1-common cartridge bag, 2-detonating material, 3-plastic detonating tube detonator, 4-sealed gas chamber, 5-counter balance pocket, 6-water-proof jacket.Common point charge (1) adopts the general industry explosive, and its weight is determined by engineering design.Detonating material (2) adopts the emulsion with cap-sensitivity, places the center of common point charge.Nonel detonator (3) adopts No. 8 metal-back blasting caps, is connected with detonator to want firm, and detonator length should add distance from embankment greater than the cartridge bag buried depth.The volume of sealed gas chamber (4) for the common drug inclusion long-pending 1/3～1/2.Counter balance pocket (5) is packed density into greater than 1.5g/cm
3Material, the volume size reaches 1.3g/cm by energy storage cartridge bag averag density
3More than calculate.Water-proof jacket (6) is made with wear-resisting plastic sheeting, and whole energy storage cartridge bag is fused.
This energy storage cartridge bag is once at the sea wall compacting mud by explosion engineering construction that rockfills, employing weight is that emulsion or the ammonium nitrate-fuel oil mixture of 24kg is processed into the energy storage cartridge bag, under same execution conditions, contrast with the common point charge that adopts same explosive, result of implementation shows, prolong the length of falling rocks body (" stone tongue "), improved the slump index (length and the degree of depth) of jackstone dike.The blasting vibration effect observed result shows that the energy storage cartridge bag also has the effect that reduces blasting vibration effect.This energy storage charge structure is simple, and handling ease, surcharge are seldom.
Claims (3)
1, a kind of energy storage cartridge bag that is used for compacting mud by explosion is characterized in that common point charge (1), detonating material (2), plastic detonating tube detonator (3), sealed gas chamber (4), counter balance pocket (5) are fused by water-proof jacket (6).
2, energy storage cartridge bag according to claim 1 is characterized in that: set up a sealed gas chamber (4) on common point charge, its volume is 1/3～1/2 of a point charge volume.
3, energy storage cartridge bag according to claim 1 is characterized in that: be provided with the counter balance pocket (5) of enough weights in the point charge bottom, the density of wherein packing into is greater than 1.5g/cm
3Material, the volume size reaches 1.3g/cm by energy storage cartridge bag averag density
3More than calculate.
