BIM-based foundation pit and surrounding stratum settlement monitoring device

Abstract

The invention discloses a BIM-based foundation pit and surrounding stratum settlement monitoring device which comprises a foundation pit, a groove is formed in the middle of the foundation pit, a top plate is fixedly mounted on one side of the surface of the foundation pit, a liquid storage tank is mounted at the top of the top plate, a plurality of static leveling instrument bodies are arranged on the surface of the groove, a bottom plate is fixedly arranged at the bottoms of the static leveling instrument bodies, a mounting groove is fixedly formed in the top of the bottom plate, a connecting plate is fixedly mounted at the bottom end of the middle of the mounting groove, lifting rods are mounted at the top of the connecting plate, a dial is mounted in the middle of the connecting plate, a high-hardness steel plate is mounted at the top end of the lifting rods, and an L-shaped connecting strip is installed at the bottom end of the middle of the high-hardness steel plate. The connecting plate, the four lifting rods and the high-hardness steel plate connected with the tops of the lifting rods are additionally arranged at the bottom of the static leveling instrument, so that the uniform height of the static leveling instrument is adjusted, and further fine adjustment can be completed while alignment is performed by the second infrared laser transmitter.

Description

technical field [0001] The invention relates to the technical field of settlement monitoring, in particular to a BIM-based settlement monitoring device for a foundation pit and its surrounding strata. Background technique [0002] Settlement observation is to observe according to the observation points set by the building and the fixed (permanent benchmark) measuring points, and the settlement degree is expressed by data. The design of buildings and structures with more than one floor requires the setting of observation points, artificial, soil foundation ( Sand foundation), etc., should be set up for subsidence observation. During construction, observation and recording should be carried out on schedule or by layer progress until completion. With the development of industrial and civil construction, various complex and large-scale engineering buildings are increasing. The construction of objects changes the original state of the ground and exerts a certain pressure on the f...

Problems solved by technology

[0003] At present, the existing BIM-based settlement monitoring devices for foundation pits and their surrounding strata on the market have the following deficiencies: 1. When using a static level to monitor changes in the stratum, due to the unevenness of the ground, the static level cannot be quickly completed. Parallel alignment makes the work efficiency low; 2. With the subsidence of the ground, the inner wall of the foundation pit will inevitably change, and the change of the inner wall cannot be understood in time; 3. After the static level and the liquid storage tank are connected to each other, most of the construction period long, it is inevitable that there will be aging of the connecting pipes, resulting in leakage during the connection; therefore, we urgently need a BIM-based settlement monitoring device for the foundation pit and its surrounding strata
