The invention discloses a multi-channel crack early warning instrument. The early warning instrument comprises a monitoring host, fixing drill rods and an alarm; the monitoring host is arranged at thefixed end of a slope, the fixing drill rods are arranged at the sliding ends of ground surface cracks, and the alarm is arranged in a residential area; the monitoring host is internally provided withtelescopic instruments, a short message alarm device and a power supply device; the telescopic instruments are respectively connected with the short message alarm device and the alarm; the power supply device is respectively connected with the telescopic instruments, the short message alarm device and a crack alarm device; the telescopic instruments are connected with the fixing drill rods through steel wire ropes, when the ground surface cracks expand and reach the set value, the telescopic instruments mechanically move to trigger the alarm to send an alarm, and the crack information is sentto a mobile phone of a mass prediction and disaster prevention monitor by the short message alarm device. By adopting the early warning instrument, manual guarding is not needed, and the developmentof cracks can be observed constantly without being restricted by the monitoring distance.
Description
technical field [0001] The invention relates to the field of geological disaster monitoring and early warning, in particular to a multi-channel crack early warning instrument. Background technique [0002] Although landslides, avalanches, and mudslides are sudden and violent, they all have obvious precursors before they occur. Measuring the cracks formed by landslides, collapses, and ground subsidence is the most effective method to avoid casualties. Common measurement methods include pile-burying, nail-burying, painting, patching, and simple automatic alarm equipment. Measure group defense method. The buried pile method is suitable for observing the cracks that occur on the landslide body. On the slope, the piles are buried across the cracks on both sides, and the distance between the two piles is measured with a steel tape measure, so as to understand the deformation and sliding process of the landslide; A nail is nailed on each side of the crack, and the deformation and...
