Settlement ring for precise self-positioning of layered settlement monitoring system and use method of settlement ring

Abstract

The invention discloses a settlement ring for precise self-positioning of a layered settlement monitoring system and a use method of the settlement ring. The settlement ring comprises a magnetic settlement ring, an installation position self-releasing bolt and a steel plate elastic fork reed. The settlement ring is characterized in that a movable precise self-positioning settlement ring is sleeved outside a settlement tube; a spring piece is arranged on the precise self-positioning settlement ring; the precise self-positioning settlement ring is fixed on the settlement tube by using the installation position self-releasing bolt; and at the same time, the spring piece is tied by using a special chain and an external traction steel wire. The structure of the precise self-positioning settlement ring is changed, the magnetism of the precise self-positioning settlement ring is increased, and the installation position self-releasing bolt, the external traction steel wire, the chain and the like are additionally arranged; the installation position self-releasing bolt is capable of precisely positioning the precise self-positioning settlement ring on a soil body to be measured; the external traction line can be easily pulled out from the chain; and the released steel plate elastic fork reed is large in elasticity and can be well embedded into the soil body, so that the displacement of the settlement ring is consistent with the displacement of the measured soil body.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering safety monitoring; in particular, it relates to a settlement ring for monitoring the settlement size of different parts inside a foundation and a geotechnical structure, which is used in a layered settlement monitoring system and has an accurate self-positioning function. The present invention also relates to such a settlement ring The use method with precise self-positioning settlement ring. Background technique [0002] The geotechnical engineering safety monitoring specification requires regular monitoring, analysis and judgment of the settlement of different parts of the foundation and geotechnical structures during the construction period or operation period, and corresponding measures should be taken. What usually adopt is to install and bury the settlement tube, put a common magnetic ring on the outside of the settlement tube, and use a layered settlement instrument to moni...

Problems solved by technology

Temporary bindings such as water ropes during the embedding of this ordinary magnetic ring cannot guarantee that the ordinary magnetic ring will not be displaced when it is placed in the settlement hole, so it is difficult to accurately determine the initial position of the ordinary magnetic ring when it is buried; The diameter of the ordinary magnetic ring is larger than the inner diameter of the ordinary magnetic ring. When the ordinary magnetic ring moves upward, it is limited by the positioning ring, which leads to distortion of the upward displacement measurement of the soil layer. On the other hand, the tension of the spring leaf of the ordinary magnetic ring is not large, and it cannot Well embedded in the hole wall of the borehole, when the soil deforms, the displacement of the ordinary magnetic ring is inconsistent with the displacement of the soil, causing a large measurement error
