A device for engineering supervision

Abstract

The invention relates to a device for project supervision. The device for project supervision comprises a main rod and an auxiliary rod, which are ball-articulated with each other at bottom ends, wherein a main slide block and an auxiliary slide block are slidably connected to the main rod and the auxiliary rod respectively, the main rod and the auxiliary rod respectively perform autoroatation limiting on the main slide block and the auxiliary slide block, the main slide block and the auxiliary slide block are hinged with connecting plates, and two groups of connecting plates are arranged on side faces of two groups of slide blocks away from each other; the main slide block is rotationally connected with a flexible rule along the axis of the main rod, and the auxiliary slide block is rotationally connected with a connecting portion fixed with an extension end of the flexible rule along the axis of the auxiliary rod; and a measurement portion for detecting an included angle between projections of the main rod and the auxiliary rod on a to-be-detected plane is arranged between the main and the auxiliary rod. By means of the above settings, the flexible rule connected between the mainrod and the auxiliary rod measures the width of a gap and records the width as initial data, and the readings of the flexible rule, which are continuously recorded subsequently, are compared with theinitial data to form analysis data of gap width changes. According to the position change between the main rod and the auxiliary rod, the change trend of the gap can be seen relatively intuitively.

[0002] After an earthquake, obvious cracks are likely to appear on the road surface or the walls of houses, and the cracks may continue. The ground or walls on both sides of the cracks may even subside, tilt or dislocate, and then widen the gaps in the cracks. Therefore, there is a safety Hidden dangers, in order to improve safety protection, it is necessary to monitor cracks, evaluate whether the road or house can continue to be used, and monitor the crustal movement in this area, etc.

[0003] At present, the most traditional crack monitoring method is to use a vernier caliper to measure the crack width of the road or house in real time, and then record the measured data to obtain the degree of crack cracking; It is difficult to accurately display the cracking of cracks, and there are certain limitations: on the one hand, each measurement cannot accurately measure the same crack, and there are large errors; on the other hand, it is impossible to measure whether the ground on both sides of the crack has cracks. In case of subsidence or dislocation

And due to the need for long-term monitoring, the number of measurements is large, and frequent carrying of tools often brings inconvenience
