Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] A comprehensive safety protection system for the blasting demolition of tall buildings (structures), in which a buffer dam 2 is built on the vertical dumping center line 6 of a towering building (structure), and a covering material 5 is laid on the buffer dam 2, and the buffer dam Sandbags 7 are stacked on the top of 2 and high-rise buildings (structures) 1 are dumped, auxiliary grooves 3 are excavated between every two buffer dams 2, shock-absorbing trenches 4 are excavated on both sides of buffer dams 2, shock-absorbing trenches 4 It is closed and communicated with the outermost auxiliary tank 3, and water is injected into the auxiliary tank 3 before blasting, and the water height is less than or equal to 50 cm.

[0014] The specific steps for installing the comprehensive protection system before the blasting demolition of tall buildings (structures) are as fo...

Abstract

The invention relates to a comprehensive safety protection system for blasting demolishing of a high-rising building (structure). Buffering dams 2 are built on a perpendicular toppling central line 6 of the high-rising building (structure)1 in pile up mode, covering materials 5 are overlaid on the buffering dams 2, sand bags 7 are stacked at the top of the buffering dams 2 and on the toppling side of the high-rising building (structure)1, an auxiliary groove 3 is dug between each two buffering dams 2, damping ditches 4 are dug on two sides of the buffering dams 2, and the damping ditches 4 are communicated with the auxiliary groove 3 at the outmost side in close mode. The comprehensive safety protection system uses buffering dam protection as a main body and the damping ditch protection and the auxiliary grooves as the auxiliary body, can reduce splash and source strength of explosion earthquakes, and effectively controls damage of grounding vibration, splashing and flying dust of the high-rising building (structure).

Description

technical field [0001] The invention belongs to the technical field of engineering blasting, and in particular relates to a comprehensive safety protection system for the harmful effect of blasting and demolition of towering buildings (structures). Background technique [0002] With the rapid development of my country's urban process, many large factories and enterprises must be relocated outside the city due to the expansion of the city scale. At the same time, in response to the national policy of energy conservation and emission reduction, many small and medium-sized thermal power units have been shut down and rebuilt. In these works, a large number of towering buildings (structures) will be faced with the demolition problems, such as tall chimneys, cooling towers and boiler racks. Due to the rapid advancement of urbanization, when demolishing these buildings, it is necessary to face many responsible factors such as high-rise buildings, vehicles passing through, and dense...
