Method for vibration reduction and ground-collision splashing prevention of building blasting demolition

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...
