Abstract

The invention discloses a device for improving the blast vibration attenuating effect of water filling shock absorbing holes and a construction method. The device comprises a plurality of shock absorbing rubber barrels installed in the water filling shock absorbing holes; each shock absorbing rubber barrel comprises an outer later waterproof rubber barrel body and an inner layer bulk solid fillingmaterial; each inner layer bulk solid filling material is completely wrapped in an inner cavity of the corresponding outer layer waterproof rubber barrel body; and a thin rope is further connected tothe outer layer waterproof rubber barrel body of each shock absorbing rubber barrel. The construction method includes the following steps that before blasting, whether the shock absorbing holes are filled with water or not is confirmed, and a certain number of shock absorbing rubber barrels are prepared for standby use; a certain single shock absorbing hole filled with water is selected, and a plurality of shock absorbing rubber barrels are sequentially placed in the shock absorbing hole and operation stops at the position of a hole opening of the shock absorbing hole; the placing work of theshock absorbing rubber barrels is carried out on other shock absorbing holes filled with water till all the shock absorbing holes are full of the shock absorbing rubber barrels; and after blasting iscompleted, the shock absorbing rubber barrels are sequentially taken out. The device and the construction method have the beneficial effects that the shock absorbing effect is good, no pollution is caused, cost is low, and reuse can be achieved.

Description

technical field [0001] The invention relates to the technical field of blasting engineering, in particular to a device and a construction method for improving the effect of water-filled drilling to reduce blasting vibration. Background technique [0002] Blasting excavation has outstanding efficiency and is currently the main excavation method for engineering rock masses such as hydropower, transportation construction and mining in my country. However, when the explosive explosion completes the loosening and excavation of the rock mass, the accompanying strong blasting vibration often causes damage to surrounding buildings. When the blasting area is close to the surrounding buildings, it is generally adopted to excavate shock-absorbing trenches or arrange several rows of shock-absorbing holes between the blasting area and the protected buildings to minimize the blasting conducted to the protected buildings. Vibration intensity, to protect the safety of the building. [000...
