Description

Earth's surface subsides monitoring devices Technical Field The utility model belongs to the field of pavement settlement monitoring, and particularly relates to a surface settlement monitoring device. Background When the ground subsidence monitoring device detects, the standard rod of the bedrock is buried in the ground at a proper depth, the leveling head and the observation plate are exposed outside, the observation plate falls on the ground, when the ground subsides, the observation plate subsides along with the ground, the standard rod of the bedrock ascends and stretches out, and then the relative height between the leveling head and the reference object is measured by carrying the measuring tool to a proper position, so that the ground subsidence condition can be observed. The existing sedimentation monitoring device comprises a guide pipe, a detection rod and a steel plate, wherein the guide pipe is inserted into the ground, the detection rod penetrates through the guide pipe and is fixed with the guide pipe, the steel plate is arranged on one side, far away from the ground, of the guide pipe, a through hole for the guide pipe to penetrate through is formed in the steel plate, and a pointer assembly is arranged on the side wall of the through hole. The steel plate is arranged on the guide pipe, the steel plate can rise and fall along with the ground subsidence, the subsidence amount of the steel plate is displayed on the monitoring rod, and the error between the subsidence amount measured by the detecting rod and the actual subsidence amount is reduced. However, the steel plate clings to the ground, so that the numerical value of the detection rod can only be read by a head strabismus pointer and a scale, and the reading error can be caused by inconvenience in one minute. Disclosure of utility model The utility model aims to provide a ground surface subsidence monitoring device which solves the problems that reading is difficult to achieve on a detection rod and reading errors exist. The technical scheme includes that the ground subsidence monitoring device comprises a horizontal plate and a transparent protective cover arranged above the horizontal plate, a graduated scale is arranged on the outer wall of the protective cover, an observation rod is arranged in the protective cover, the observation rod penetrates through the center of the horizontal plate and is movably connected with the horizontal plate, a subsidence plate is arranged at the bottom end of the observation rod, a reading standard rod is arranged at the top end of the observation rod, and two ends of the reading standard rod are in sliding connection with the protective cover. Preferably, the indent of the end part of the reading marker post is provided with a groove, the outer end of the groove is provided with a rotating shaft, the rotating shaft is rotationally connected with a ball, the ball part extends out of the reading marker post and is in rolling connection with the inner wall of the protective cover, a reading pointer is arranged above the ball, one end of the reading pointer is connected with the middle part of the top end of the reading marker post, and the other end of the reading pointer horizontally extends to the inner wall of the protective cover and does not extend out of the outer end of the ball.
