Barrier device with function of easily adjusting size for engineering blasting

Abstract

The invention discloses a barrier device with a function of easily adjusting the size for engineering blasting. The barrier device comprises fixing rods, barrier plates and a base, wherein the fixingrods are uniformly installed on the top of the base, supporting corner brackets are installed at the positions where the bottoms of the fixing rods are connected with the base respectively, fixing sleeves are arranged on the fixing rods respectively, and the barrier plates are arranged on one sides of the fixing sleeves respectively. Fixing bases are uniformly installed on one sides of the barrierplates respectively, the fixing bases are fixedly connected with the fixing sleeves, and shock-absorption plates are arranged on the sides, away from the fixing bases, of the barrier plates respectively. According to the barrier device with the function of easily adjusting the size for engineering blasting, by arranging water-penetration membranes and water-absorption sponge, when stones spattered in the blasting process squeeze the shock-absorption plates and the barrier plates, water absorbed in the water-absorption sponge easily seeps out of the water-penetration membranes after being squeezed and overflows through water outlets, dust generated during blasting is effectively wrapped, less dust rises, and therefore, the pollution of the dust to the environment is reduced.

Description

technical field [0001] The invention relates to the technical field of engineering blasting, in particular to a barrier device for engineering blasting that is easy to adjust in size. Background technique [0002] With the continuous development of society, my country needs to use engineering blasting to carry out construction in railway construction, mining and urban demolition. Engineering blasting technology uses the huge energy generated by the explosion of explosives to destroy the original structure of an object. , during the blasting process, a large amount of splashed gravel, dust and noise will be generated, which will easily cause certain harm to the surrounding environment, so it needs to be used in conjunction with the corresponding barrier device. The existing barrier devices for engineering blasting have the following points in use defect: [0003] 1. Most of the existing barrier devices for engineering blasting are fixed in size, and the barrier size cannot be ...
