Method for monitoring foundation settlement by using static water level gauge and static water level gauges used in method

Abstract

The invention provides a method for monitoring foundation settlement by using a static water level gauge and static water level gauges used in the method. Each static water level gauge is provided with a liquid communication opening; one static water level gauge is set to be a standard point and one static water level gauge is arranged at each point of a plurality of points to be measured; the liquid communication opening of the liquid container of the static water level gauge at the standard point is connected in series with the liquid communication openings of liquid containers of the static water level gauges at the points to be measured through liquid communication pipes. The static water level gauges are characterized in that: a liquid container air vent is arranged at the top part of the liquid container of each static water level gauge and a pressure senor cabin air vent is arranged on a pressure senor cabin, so that the influences of temperature and pressure of atmosphere are eliminated; based on a water level balance principle, a time slot foundation settlement value of a point to be measured is a difference value between a liquid level height hi of the static water level gauge at the point to be measured and the liquid level height h0 of the static water level gauge at the standard point, namely delta hi=h0-hi. According to the invention, the problem that a static water level system is easily affected by temperature and atmosphere change is solved.

Description

technical field [0001] The invention relates to a building settlement monitoring method, in particular discloses a method for monitoring foundation settlement with a static level, which is suitable for the settlement monitoring of buildings such as bridges, dams and houses, and belongs to the field of civil engineering detection. Background technique [0002] Construction on the ground, such as buildings, bridges, dams, etc., will cause foundation settlement. Static levels are common equipment for monitoring such settlements. Most of the static levels in the past adopt the float type detection method, and the water level is converted into an electrical signal by a displacement sensor, and then read out by a secondary instrument. This type of method has two significant defects: that is, the volume of the liquid is significantly affected by atmospheric pressure and temperature. will lead to large measurement errors. To eliminate these effects, it is necessary to add addition...
