The invention discloses a blasting vibration ultra-wideband signal receiving detector in construction using a borehole-blasting method. The blasting vibration ultra-wideband signal receiving detector comprises an optical cable, a connector, a detection core, a detector clamping groove, a detector sleeve wall and detector separators. The optical cable passes through the connector; the connector is arranged at an upper end of the detector sleeve wall; an optical cable core at a front end of the optical cable is connected with the detection core; a lower end of the detection core is clamped in the detector clamping groove; an outer side of the detection core is connected with the detector separators; outer sides of the detector separators are provided with the detector sleeve wall; and a composite cementing material is densely filled between the optical cable and the connector, and between the optical cable core and the detection core. The invention further discloses an application method of the blasting vibration ultra-wideband signal receiving detector. The blasting vibration ultra-wideband signal receiving detector provided by the invention has the advantages of simple structure, high detection precision, interference resistance, convenience in measurement, high measurement coupling precision and the like.
Description
technical field [0001] The invention relates to a signal identification technology, in particular to an ultra-wideband signal receiving detector and a using method of blasting vibration in drilling and blasting construction. Background technique [0002] Tunnel engineering is a kind of geological engineering. Although the tunnel design and engineering geological survey before construction predict and predict the geological conditions of the tunnel to a certain extent, due to the complexity of the rock mass, the survey data and the tunnel excavation The actual situation may be quite different. There are a large number of tunnel projects in the field of water conservancy, hydropower and transportation in my country. Geological disasters in tunnel engineering are the key factors restricting tunnel construction. Often due to the unknown geological conditions in front of the tunnel, unpredictable geological disasters often occur, such as water inrush, mud inrush, collapse, rock f...
