SEABED CRUSTAL MOVEMENT OBSERVATION DEVICE
To reduce the time required for convergence in consolidation of seabed sediments by a weight part.SOLUTION: A seabed crustal movement observation device has a weight part 2 installed on the seabed. The weight part 2 has a weight body 21 being shaped approximately plate-like or approximately block-like, a discharge hole 22 that penetrates the weight body 21 in the vertical direction and an entry suppression part 23 provided inside the discharge hole 22 or in a lower opening 222 to prevent particles of seabed sediment from entering the discharge hole 22. Therefore, when the weight part 2 is installed on the sediment such as silt, clay, sand, etc. on the seabed, it is possible to prevent the inside of the discharge hole 22 from being filled with the particles of the sediment, and to appropriately discharge the interstitial water of the sediment from the discharge hole 22. As a result, it is possible to shorten the time required for convergence in the consolidation of the deposit by the weight part 2.SELECTED DRAWING: Figure 2
【課題】錘部による海底の堆積物の圧密において、収束に要する時間を短縮する。【解決手段】海底地殻変動観測装置は、海底に設置される錘部２を有する。錘部２は、略板状または略ブロック状の錘部本体２１と、錘部本体２１を上下方向に貫通する排出孔２２と、排出孔２２の内部または下開口２２２に設けられ、海底の堆積物の粒子の当該排出孔２２内への進入を抑制する進入抑制部２３とを有する。これにより、錘部２が海底のシルト、粘土、砂等の堆積物上に設置された際に、排出孔２２の内部が堆積物の粒子で埋まることを抑制して、排出孔２２から堆積物の間隙水を適切に排出することができる。その結果、錘部２による堆積物の圧密において、収束に要する時間を短縮することができる。【選択図】図２
