Settlement observing pre-embedded piece, settlement observing device and installation device

Abstract

The invention provides a settlement observing pre-embedded piece. The long arm segments of two L-shaped supports are inserted in through holes of the corresponding short arm segments in a sleeving way, so that a square framework is defined by the two L-shaped supports; the settlement observing pre-embedded piece is in tight contact with the wall of an observing hole through a contact pin; and the settlement data of a soil body can be known by measuring the distance that the settlement observing pre-embedded piece moves along with the soil body. The invention also provides a settlement observing device and an installation device based on the settlement observing pre-embedded piece. The settlement observing pre-embedded piece, the settlement observing device and the installation device have beneficial effects that the settlement observing pre-embedded piece is simple in structure, convenient to install, and reusable after being detached; by virtue of the settlement observing pre-embedded piece, the measuring process is completely realized through a mechanical mode; and the measuring process is simple and the result is correct and reliable.

Description

technical field [0001] The invention relates to a soil layered settlement measurement technology, in particular to a settlement observation embedded part, a settlement observation device and an installation device. Background technique [0002] Settlement observation is a basic work in the deformation observation of construction engineering. With the vigorous development of my country's construction industry and traffic construction, the work of settlement observation is becoming more and more important, especially in underground engineering and foundation engineering construction. Due to The increase of the overlying load on the soil or the decrease of the groundwater level will cause a certain amount of settlement of the soil. In order to ensure the safety of buildings and personnel and minimize the impact of engineering construction on the geological environment, we need to The subsidence of the soil can be monitored layer by layer, and the actual settlement data can also b...

Problems solved by technology

Among them, the combined GPS measurement of bedrock markers and layered markers is cited in the "Technical Specifications for Land Subsidence Monitoring and Prevention in Shanghai". Although it is suitable for long-term monitoring in large areas and has a high degree of automation and intelligence, it is still At the same time, there are problems of high price and low precision; the magnetic ring type sedimentation instrument is simple in equipment and easy to operate, but in the implementation process, the magnetic probe is manually lowered, and the human error is large. If the distance between the magnetic rings is small, the magnetic minerals in the soil When the substance content is high, it will affect the magnetic induction of the probe, and the accuracy of the steel ruler is ±1mm, the overall error is large and the accuracy is low
