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.

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.
