Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to a foundation settlement detection device. Background Art

[0002] Foundation settlement refers to the sinking of the foundation surface caused by the compaction of the foundation soil layer under the action of additional stress. Excessive settlement, especially uneven settlement, will cause the building to tilt and crack and become unusable. Therefore, the foundation settlement value needs to be tested during and after the construction of the building to prevent the building from being unusable due to excessive settlement values.

[0003] Existing methods for detecting foundation settlement often use precise engineering levels and accurately scaled level rods for detection. Usually, during the detection, settlement can be detected at a certain position, but the specific value of the settlement is not easy to read, and there will be inclination when the foundation settles, and the inclination data is not convenient to read specifically. After the settlement position is detected, in order to facilitate data comparison, it is necessary to record various settlement data. In the record, orientation is also a very important data, but it is not convenient to measure; in response to the above problems, we propose a foundation settlement detection device.

When there is settlement, the detection plate 12 moves downward, and the sinking value is determined by observing the scale line on the detection plate 12; When the detection plate 12 moves downward, it drives the rack 14 to move downward, and then drives the gear 15 to rotate, drives the rotating rod 13 to rotate, and drives the pointer rotating shaft in the angle dial mechanism 22 to rotate through the pulley mechanism 16, reads the reading on the angle dial mechanism 22 pointed by the pointer rotating shaft, and calculates the settlement inclination; The support horizontal plate 11 is rotated to drive the displacement height detection mechanism 2 and the longitudinal inclination detection mechanism 3 to rotate, so as to detect the inclination and settlement of the surroundings; When the supporting cross plate 11 is rotated, the rotating ring 10 and the base ring 9 are driven to rotate. When the base ring 9 is rotated, the arc plate 27 is driven to rotate, and then the supporting plate 28 is driven to rotate, and then the fixed supporting plate 30 is driven to rotate, and then the arc jacking plate 31 is driven to rotate. The arc jacking plate 31 contacts the columnar rod 34, and the columnar rod 34 moves upward, driving the connecting rod body 32 to move upward, so that the connecting rod body 32 comes out of the fixed supporting column 8 and rises to the upper end of the supporting plate 28, so as to avoid the connecting rod body 32 hindering the rotation of the supporting plate 28. At the same time, the other two groups of connecting rod bodies 32 are extended into the fixed supporting column 8 under the pressure of the spring 33, so as to limit the rotation of the angle dial 24 and ensure its stability. The azimuth position can be clearly detected by the rotating angle indicator needle through the angle dial 24.
