Problems solved by technology

[0003] Pile foundation blasting is different from ordinary blasting. The impact force and flying rocks of pile foundation blasting can only be discharged through the hole of the blast hole, so it is necessary to protect the blast hole to prevent the blasting impact from causing damage to equipment or personnel near the blast hole. At present, there is no device on the market that can effectively protect the blasting hole of pile foundation blasting

The pile foundation blasting protection device comprises a base, movable rods, a top plate, a buffer plate, a moving assembly and a first buffer assembly, four first through holes are formed in the base, the four movable rods are installed in the four first through holes correspondingly, and the top ends of the movable rods are fixedly connected with the top plate; the buffer plate slidably penetrates through the movable rods and is provided with a protective skirt, the moving assembly is installed on the lower surface of the base, the first buffer assembly comprises a first spring, the movable rods are sleeved with the first spring, the top end of the first spring is connected with the buffer plate, the lower surface of the buffer plate is provided with an offset cone, and the base is provided with a second through hole; and the second through hole corresponds to the offset cone. According to the technical scheme, the pile foundation blasting protection device has the beneficial effects that the protection effect is good, and backfilling is avoided.

Description

technical field [0001] The invention relates to the technical field of blasting protection, in particular to a pile foundation blasting protection device. Background technique [0002] Blasting is a technology that uses the compression, loosening, destruction, throwing and killing effects of explosives in air, water, earth and rock media or objects to achieve the intended purpose. When the explosive package or charge explodes in the earth-rock medium or structure, the earth-rock medium or structure will be compressed, deformed, destroyed, loosened and thrown. It is mainly used in earthwork engineering, and the demolition of metal buildings and structures. The scope of the research includes: the properties and usage methods of explosives and firearms, the explosive effect of charges (charges) in various media, the contact blasting and non-contact blasting of charges on targets, and the organization and implementation of various blasting operations . [0003] Pile foundation...
