THE MONITORING SYSTEM FOR MEASURING IMPACT FORCE AND DREDGED SEDIMENT AMOUNT OF DEBRIS FLOW USING EARTH PRESSURE CELL AND THE MAINTENANCE METHOD OF DREDGED SEDIMENT BEHIND DEBRIS FLOW BARRIER

摘要

The present invention relates to an apparatus for measuring pressure, impact force and deposit amount of debris accumulated in a four-way dam using a earth pressure meter, A debris flow measurement unit installed at a part of the earth pressure system to measure the pressure and the impact force of the earths stone; A measurement unit fixing member provided at a part of the rear dam surface and fixing the debris flow measurement unit to a part of the four-way dam; And a management server connected to the debris flow measurement unit for receiving information from the debris flow measurement unit and storing and analyzing the information. The method for connecting the debris flow measurement unit to the four- Wherein the recesses corresponding to the recesses are formed in the vertical direction and the recesses are accommodated in the recesses and the recesses are detachably fixed to the measuring unit fixing member. It is possible to directly measure the impact force acting on the four-way dam when a landslide landslide occurs by installing a large number of earth pressure systems in the vertical direction on the back of the four-way dam. Therefore, when the dredged sediment accumulates on the back of the four- Stability and maintenance of dredged sediments are possible.
