Problems solved by technology

[0004] Due to the explosive reaction in a closed container, in these two technologies, the quality of the substances and explosives involved in the explosive reaction is strictly limited
The manufacturing cost of the reaction device and the reactor is relatively high
Moreover, neither of these two technologies can meet the following special requirements, that is, in the process of explosive impact forming materials, not only the interface between explosives and...

Embodiment Construction

[0014] Firstly, choose a flat stratum (1), and the stratum (1) is preferably evenly distributed undisturbed soil. A vertical shaft with a circular cross-section is dug downward from the surface. The upper part of the shaft is used as a channel (2) for lowering explosives and materials, and the lower part is used as a storage bin (3). The material (4) is lowered into the silo (3) through the channel (2). Place the explosive charge (5) on top of the material (4). The upper part of the explosive charge (5) and the material (4) is uniformly covered with a plug (6) of suitable thickness. Place the mold (8) on the top of the sand material, and pass the hole (9) on the mold (8) through the detonating cord (11) of the detonating charge (5) simultaneously. Lead the detonating cord (11) to the surface. Continue to backfill the plug (6) into the channel (2). Index the explosive charge cartridge (5) through the detonation. After the material (4) is solidified, the formation (1) is e...

Abstract

The invention discloses a method for forming a building material in a mode of dynamite explosive blast, which comprises the following steps: digging out a passage (2) and a bin (3) for placing dynamites and materials in a stratum (1), and pouring quantitative amount of a material (4) in the bin (3); placing an explosive cartridge (5) at a position which can contact the material (4); backfilling blockages (6) and fixing a mould (8) in the passage (2); and detonating the explosive cartridge (5) to obtain a material (7) generated under the action of explosive blast. The material (4) is either a hydrous fluid or gel state material or an unhydrous single substance particle or a mixture of a few types of substances. The method uses the stratum as a restraint body for restricting the range of the explosion reaction, thereby having greater flexibility and plastic deformation capacity, safe operation and low cost.

Description

technical field [0001] The invention belongs to the technical field of explosive explosion and material manufacture. The invention relates to a method for forming building materials by explosion, in particular to a method for forming building materials in formations through the explosive impact of explosives. The invention is particularly suitable for the study of the properties of building materials formed under extreme conditions. Background technique [0002] The prior art in this technical field can refer to a disclosed Chinese Patent No. ZL91106989.5 titled "Method and Device for Explosively Manufacturing Diamond" and a Chinese Patent No. CN01131678.0 disclosed titled "A nitro-containing The method of preparing carbon nanotubes by the explosion of organic explosives" patented technology. [0003] These two invention patents are based on the reaction device or reactor obtained by mechanical processing, and one or several substances and explosives are placed in the reac...
