Embodiment Construction

[0025] The deformation measurement device of the building foundation under the influence of mining, including the inclinometer rod and the total station, the number of the inclinometer rod is at least 4, vertically inserted into each corner of the outer edge of the building, and located in the foundation other than the building foundation, A dual-axis inclination sensor is installed horizontally on the inclinometer pole, and there are measurement marks on the top of the inclinometer pole. The total station is located outside the building, aiming at each measurement mark, and measuring the relative position data of each measurement pole. This embodiment is applicable to the situation where the distribution of buildings is relatively scattered. When the distribution of buildings is concentrated, the inclinometer rods can be distributed in a grid to measure the foundation deformation of the buildings in the entire residential area.

[0026] The measuring rod is made of plastic or ...

Abstract

The invention aims to solve the problem of how to measure deformation of a building foundation. A deformation measuring device for a building foundation under mining influence comprises at least fourmeasuring inclined rods and a total station, wherein the measuring inclined rods are inserted into corners of the outer edge of a building, and are positioned in a foundation outside the building foundation; double-shaft tilt angle sensors are horizontally mounted on the measuring inclined rods; measuring marks are arranged on the tops of the measuring inclined rods; and the total station is positioned outside the building to align to each measuring mark and measure relative position data of each measuring rod. The double-shaft tilt angle sensors on the measuring inclined rods can reflect inclination and torsion deformation of the building foundation, and relative position data, measured by the total station, of the measuring inclined rods can reflect relative horizontal movement and settling of each part of the foundation. The device can comprehensively measure deformation of the building foundation.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to the deformation measurement of building foundations under the influence of mining. Background technique [0002] The mining of underground minerals will affect the stability of the building structure on the ground to a certain extent, and even cause the deformation and damage of the building. Therefore, the mining unit needs to compensate for its losses. [0003] At present, compensation standards for losses are mainly based on the width of building cracks and other structural deformation characteristics. This has brought about some problems. 1. Due to other non-mining factors, the building itself will also undergo structural deformation. It is difficult to judge whether the damage is caused by mining, which makes it difficult to determine the nature of compensation; 2. Mining The deformation of the building under the influence has a great relationship with its structural st...
