Measuring device for deep subsidence of soil mass and its application method

Abstract

The invention discloses a device for measuring deep settlement of soil and a using method of the device. The device for measuring deep settlement of the soil comprises a settlement plate sleeve, an upper steel plate, a lower steel plate, a first gear, at least two second gears, an extending rod, at least two metal rods and at least two settlement fan blades. The second gears are rotatably arrangedbetween the upper steel plate and the lower steel plate, and the first gear is engaged with the second gears. The metal rods correspond to the second gears one by one, the upper ends of the metal rods are fixed to the centers of the lower surfaces of the corresponding second gears, and the lower ends of the metal rods go downwards vertically and sequentially penetrate through the lower steel plate and the lower end of the settlement plate sleeve. The settlement fan blades correspond to the metal rods one by one, one ends of the settlement fan blades are perpendicularly connected to the lowerends of the corresponding metal rods. The device has the advantages of being low in cost, accurate in measure, capable of being recycled and the like, and can be widely applied to equipment and the technical field for measuring deep settlement of the soil.

Description

technical field [0001] The present invention relates to the field of measuring equipment and technical field of deep subsidence of soil, more specifically, the present invention relates to a measuring device for deep subsidence of soil and its application method. Background technique [0002] At present, the magnetic ring type settlement instrument is the most commonly used equipment for deep foundation settlement, but it also has many shortcomings. 1) First of all, there is an error in the equipment itself. The accuracy of the probe’s induction of the magnetic ring signal is generally 1cm. The data measured when the probe is up and down is different, and the average value is often used; 2) The up and down of the magnetic ring is not easy to match the soil The deformation of the body must be consistent, because the magnetic ring must be able to slide freely on the outer wall of the core tube on the one hand, and on the other hand, it must be well integrated with the surround...

Problems solved by technology

1) First of all, there is an error in the equipment itself. The accuracy of the probe’s induction of the magnetic ring signal is generally 1cm. The data measured when the probe is up and down is different, and the average value is often used; 2) The rise and fall of the magnetic ring is not easy to match the soil The deformation of the body must be consistent, because the magnetic ring must be able to slide freely on the outer wall of the core tube on the one hand, and on the other hand, it must be well combined with the surrounding soil, and it is difficult to have both

The practical application in engineering shows that the data measured by the magnetic ring method is not ideal, and the data is rather messy and irregular
