Example 1 is shown in fig. 1-2: a method for destroying waste aerial shells comprises the following steps:

the calculation of the safety radius should be performed using r= (K/V) 1/α×q1/3 when selecting the destruction field, where the letters have the following meanings:

r is the safe radius distance of blasting earthquake, m; q-amount of explosive, kg; taking the total explosive amount by simultaneous blasting; taking the maximum one-section dosage from differential blasting or second differential blasting; v-safety speed of earthquake to building; K. the alpha-coefficient and attenuation index related to conditions such as blasting point topography, geology and the like can be selected according to table 1. Or determined experimentally.

Lithology of rock	K	α
			Hard rock	50-150	1.3-1.5
Medium hard rock	150-250	1.5-1.8
			Soft rock	250-250	1.8-2.0

According to the formula, the minimum safety radius required by the destruction site is calculated, the space site which is closest to the excavated space site is searched for by taking the excavated space site as the center of a circle according to the minimum safety radius, the minimum safety radius is met, and fault geology cannot be found at the selected site of the destruction site.

after the destroying field is determined, excavating destroying pits at the middle position of the destroying field by using an excavator, and if a plurality of destroying pits exist, keeping the distance between the pits to be not less than 15m. The size of the destroying pit should be larger than the length and width of the bomb by 20cm, the depth should be not smaller than 4m, and a pit-descending ramp should be constructed on one side of the destroying pit, so that workers can conveniently enter the pit to carry out pit bottom horizontal trimming, the bomb is placed, and the explosive-inducing explosive package is installed.

The soil and stone medium of the destroying pit is excavated and directly bagged, the retaining wall is piled up around the edge of the pit mouth of the destroying pit, the short wall is piled up to be not lower than 1.2 meters, and when the earth and stone is not enough to be excavated, sand and stone piles can be utilized for bagging and piling, so that the method has the advantages that besides the destroying pit is used for blocking the blasting flyer, the retaining wall also plays a role of secondarily blocking the blasting flyer.

Step three, transporting the aeroshell: classifying the extracted missiles according to the presence or absence of fuzes, respectively loading the fuze-containing missiles and the fuze-free missiles into different bomb loading boxes, wherein the bomb loading boxes are solid wood boxes, and fine sand is filled around the inside of the boxes to ensure that the projectiles have no displacement space, and transporting the projectiles to a destruction field by using vehicles after the boxing is completed;

the body of the few dredged bombs is severely corroded, and the following measures are adopted to ensure the safety during transportation:

1. the ammunition with and without fuzes should be packed separately;

2. and packaging all the aeroshell to be destroyed by adopting a wooden box. The specification of the wooden case is slightly larger than that of the bomb; the space of 20cm is reserved in the upper, lower, left and right sides of the bomb in the box body, the wooden box is made of a wood board with the thickness of 1.5cm, fine sand materials are paved in the box body, and the box body is not covered;

thirdly, after the bomb with unknown fuze state is packed, the distance between the fuze position and the edge of the wooden box is ensured to be more than 200mm, sand is filled around the bomb, and no displacement space of the bomb is ensured. The gaps in the packaging box (box) are all filled with soft inert materials (fine sand).

the explosion-inducing explosive package adopts emulsion explosive with 90 phase volume fraction, and the destruction of aeroammunition belongs to external contact explosion, so that equivalent conversion is needed when the TNT is replaced by the emulsion explosive, and the conversion is mainly dependent on the explosive strength and explosion speed. The intensity of the TNT explosive is 16mm, and the detonation velocity is 6825m/s; the emulsion explosive has a violence of not less than 12mm and a detonation velocity of 3200m/s. The equivalent conversion coefficient of the emulsion explosive and the TNT explosive is thus e= (12/16+3200/6825)/2=0.61. The calculation shows that the explosive package of the emulsion explosive with the C more than or equal to 2kg can be used for implementing the explosion-inducing bomb, so that the bomb can be ensured to be completely explosion-induced.

According to the calculation, in order to ensure reliable detonation and destruction to be thoroughly and reliably carried out, the placement positions of the explosion-inducing explosive packages are shown in fig. 1, 1 emulsion explosive explosion-inducing explosive package 2 of 2kg is placed at the fuze positions of the warhead and the warhead of the bomb 1, and as the fuze is not arranged in the middle of the bomb, and the wall thickness is thicker than that of the warhead and the warhead, 1 emulsion explosive explosion-inducing explosive package 2 of not less than 4kg is placed in the upper part of the middle of the bomb, so that reliable detonation and destruction to be thoroughly and reliably carried out are ensured.

assuming that four air bombs need to be destroyed, four destruction pits 3 are dug, the detonating circuit is shown in fig. 2, the destruction pits 3 are divided into a first pit, a second pit, a third pit and a fourth pit, and the delay detonators 4 used by each destruction pit 3 are separated by 150ms, so that the delay detonators 4 of the first pit, the second pit, the third pit and the fourth pit are respectively connected by using instantaneous power detonators by adopting 0ms, 150ms, 300ms and 450ms, the instantaneous power detonators are formed into a series electric detonating circuit, and the electric detonators 5 are used for detonating once.

Example 2: the difference between this embodiment and embodiment 1 is that, as shown in fig. 3, the bomb loading chamber 6 includes a loading chamber 61 and a buffer chamber 62, in which flexible material (such as fine sand) is required to be filled in the loading chamber 61 as in embodiment 1, a supporting plate 611 is provided between the loading chamber 61 and the buffer chamber 62 to separate the loading plate 611 from the side wall of the bomb loading chamber 6, a vertical supporting rod 63 is provided on the lower bottom surface of the supporting plate 611, the upper end of the supporting rod 63 is welded to the supporting plate 611, a buffer plate 641 is welded to the lower end of the supporting rod 63, and the buffer plate 641 is also relatively slid to the side wall of the bomb loading chamber 6, so that the supporting plate 611 and the buffer plate 641 form a whole through the supporting rod 63.

Buffer plate 641 is located buffer chamber 62 to separate buffer chamber 62 into upper buffer chamber and lower buffer chamber, provided with vertical air spring 64 in the lower bottom surface of buffer plate 641, the bottom in buffer chamber plays the supporting role to buffer plate 641 under the air spring 64 connection, and air inlet of air spring 64 is connected with air compressor 65 through intake pipe 651.

A buffer pipe 621 is arranged on the left side wall of the buffer cavity 62, the buffer pipe 621 connects the upper buffer cavity with the lower buffer cavity, a water flushing wheel is arranged on the buffer pipe 621, and the lower buffer cavity is filled with hydraulic oil.

When the bomb loading box 6 is used for loading the bomb, air can be pressed into the air spring 64 by the air compressor 65, at the moment, the air spring 64 starts to expand upwards to push the buffer plate 641 to move upwards, the supporting rod 63 is used for fixing the buffer plate 641 and the supporting plate 611, the supporting plate 611 also moves upwards, after fine sand on the supporting plate 611 is flush with the opening of the bomb loading box 6, the bomb is adjusted to the supporting plate 611, at the moment, the air leakage opening of the air spring 64 is opened, the air compressor 65 is closed, and the air spring 64 starts to fall back to the initial position. The lifting of the carrier plate 611 by the air spring 64 facilitates loading of the air spring, and after loading, the loading cavity 61 needs to be filled with flexible material, such as fine sand.

In the transportation process of the bomb, the transport vehicle may be subjected to uneven ground and jolt, so that the bomb is vibrated. When the bomb vibrates, the bomb moves downwards to extrude the bearing plate 611, the bearing plate 611 moves downwards under the force of the force, and the bearing plate 611 and the buffer plate 641 are fixed, so that the buffer plate 641 moves downwards to extrude the air spring 64, the air spring 64 begins to deform to buffer the buffer plate 641, the vibration of the buffer plate 641 is relieved, and the vibration of the bearing plate 611 is further relieved. And in the downward motion of buffer plate 641, buffer plate 641 can extrude the hydraulic oil in the lower buffer chamber for the hydraulic oil in lower buffer chamber passes through buffer pipe 621 and gets into the buffer chamber, and hydraulic oil moves to the eminence from the low side, turns into the potential energy with the kinetic energy of vibrations, and then absorbs the energy that the vibrations brought, still can strike the water-washed wheel in buffer pipe 621 when hydraulic oil passes through buffer pipe 621, makes the water-washed wheel take place to rotate, turns into the mechanical energy that the water-washed wheel was rotatory with the kinetic energy that loading board 611 vibrations.

When bump is faced, the bomb loading carton 6 utilizes the air spring 64 to absorb shock, so that the bomb is prevented from vibrating greatly, and then the hydraulic oil and the water-jet wheel are utilized to absorb energy, so that the bomb is stable and safe in the transportation process.
