一种地面沉降水准测量监测装置

Surface subsidence leveling measuring and monitoring device

Abstract

The utility model discloses a surface subsidence leveling measuring and monitoring device. The device comprises a leveling markstone provided with a leveling mark and further comprises a protective layer matched with the leveling markstone and used for sleeving the periphery of the leveling markstone, wherein when the protective layer sleeves the periphery of the leveling markstone, a space is reserved between the protective layer and the leveling markstone; the protective layer is a cement protective barrel; the leveling markstone comprises a base and a vertical column connected with the base; the vertical column stands on the base vertically; the protective layer is matched with the periphery of the vertical column; a space between the protective layer and the periphery of the vertical column is packed with a buffering layer; the bottom of the protective layer is flush with the top of the base; the top of the protective layer is higher than that of the vertical column; the protruding part isn't packed with the buffering layer; the top of the protective layer is covered by a top cover; the buffering layer is a fine sand layer. According to the utility model, not only can the device effectively overcome the difficulties that the leveling markstone is damaged due to earth surface level deformation or soil layer lateral extrusion force, but also the vertical change features of the earth surface can be obtained, so that the surface subsidence measuring value is more accurate.
本实用新型公开了一种地面沉降水准测量监测装置,包括具有水准标志的水准标石,还包括与所述水准标石配套的、用于套在水准标石外围的保护层,所述保护层套在水准标石外围时,保护层与水准标石之间留有空间。保护层为水泥保护筒。水准标石包括基座及与基座连接的立柱,立柱垂直立于基座上;保护层与立柱外围配合,两者之间的空间填有缓冲层。保护层的底部与基座顶部齐平,保护层的顶部高于立柱的顶部,高出部分不填充缓冲层。保护层的顶部覆盖有顶盖。缓冲层为细沙层。本实用新型既能有效的克服因地表水平形变或土层侧向挤压力导致的水准标石破坏,又能得到地表形变垂向变化特征,使地面沉降测量值更加准确。
