Embodiment Construction

[0032] Below in conjunction with example, illustrate the embodiment of the present invention.

[0033] An 18-storey building is 63m in height, 21m in length, and 43m in width. There are residential buildings at 6m to the south, gas station facilities at 11m to the north, underground natural gas pipelines at 10m to the west, and factories and schools to the east at 40m. Double-fold in the same direction, and the collapse direction is due east.

[0034] During the blasting design process, after the safety check, the calculated value of the vibration generated by the collapse of the building is about 10 times higher than the allowable value of the vibration safety of the surrounding environmental facilities. Secondary splashing, adopted the present invention "a kind of method for building blasting demolition vibration reduction and anti-ground splash" to carry out vibration reduction and anti-ground splash, the steps are as follows:

[0035] (1) Refer to figure 1 As shown, with...

Abstract

The invention discloses a method for vibration reduction and ground-collision splashing prevention of building blasting demolition. The method comprises the following steps: building a plurality of sandy soil embankments within a collapsing range in a collapsing direction of a building; laying a double-layer fine-mesh nylon protection screen within the range; fully laying waste tires on the protection screen; laying waste tire rubber sheet on the tires; digging an annular ditch in the ground outside the building and the collapsing range; erecting a grid outside the collapsing range of the building, and arranging the double-layer fine-mesh nylon protection screen; recovering the waste tire rubber sheet, the waste tires and the like after the completion of deslagging; and filling the ditch with the sandy soil of the sandy soil embankments, and levelling the site. According to the method, the vibration generated by the collapsing ground-collision of the building during a building blasting demolition process is effectively reduced, the influence of the vibration generated by cut blasting and the vibration generated by the collapsing ground-collision of the building on surrounding facilities is effectively reduced, and the vibration harm generated by the building blasting demolition and the splashing harm caused by the ground-collision is effectively prevented, thus the safety and environment friendliness of the blasting demolition operation are improved.

Description

technical field [0001] The invention belongs to the technical field of demolition blasting, and in particular relates to a method for vibration reduction and ground splash prevention of building blasting demolition. Background technique [0002] With the progress of society and the development of urban construction, the transformation of old urban areas has become an important part of the government's work. At the same time, due to the development of urban construction, the urban construction environment is becoming more and more complex. In the renovation project of the old city, demolition and blasting construction method is increasingly widely used due to its high efficiency and controllable production safety. However, in complex environments, hazards such as blasting vibration, collapse ground vibration, and secondary splash generated by building collapse and ground impact during the demolition process of buildings seriously threaten the safety of surrounding environment...
