AI Technical Summary

Problems solved by technology

In the process of injecting the standard sand, due to the relatively large flow rate of the standard sand, and under the action of its own gravity, the standard sand located below will accumulate relatively solidly, that is, the density of the standard sand located below is greater than that of the standard sand located above. Density, resulting in poor density uniformity of the standard sand in the cylinder, which in turn affects the measurement results

Embodiment 1

[0029] see figure 1 As shown, the present embodiment provides a sand filling cylinder, including a cylinder body, the cylinder body has a sand injection port 103, and a standard sand disperser is provided inside the cylinder body, and the standard sand disperser is used to pour sand from the sand injection port 103 The standard sand in the cylinder is dispersed to the side wall of the cylinder.

[0030] Based on this structure, the sand filling cylinder provided in this embodiment can disperse the standard sand falling into the cylinder body from the sand injection port 103 to the side wall of the cylinder body by setting the standard sand disperser, which is equivalent to The inner wall of the cylinder falls into it, instead of falling into the cylinder instantaneously from the middle position, so that the standard sand is not easy to accumulate excessively.

[0031] The shape of the cross section of the barrel in this embodiment is circular.

[0032] Further, in some optio...

Embodiment 2

[0055] This embodiment provides a sand filling instrument, which includes a base plate and the sand filling cylinder provided in Embodiment 1 of the present invention, and the sand filling cylinder is placed on the base plate.

[0056] The sand filling instrument provided in this embodiment can effectively alleviate the excessive accumulation of standard sand at the bottom of the cylinder due to the use of the sand filling cylinder provided in Embodiment 1 of the present invention.

Abstract

The invention relates to the technical field of sand filling method measuring instruments, in particular to a sand filling cylinder and a sand filling instrument. The sand filling cylinder comprises acylinder body, the cylinder body is provided with a sand filling port, a standard sand disperser is arranged in the cylinder body, and the standard sand disperser is used for dispersing standard sandfalling into the cylinder body from the sand filling port to the side wall of the cylinder body. According to the sand filling cylinder and the sand filling instrument, the standard sand disperser isarranged, the standard sand falling into the cylinder body from the sand filling port can be dispersed to the side wall of the cylinder body, and thusthe standard sand is not prone to excessive accumulation.

Description

technical field [0001] The invention relates to the technical field of sand filling method measuring instruments, in particular to a sand filling cylinder and a sand filling instrument. Background technique [0002] The sand filling instrument is a geotechnical instrument, which is suitable for measuring the bulk density of sandy soil, gravel soil, sandy gravel material, graded gravel, cement stabilized soil, lime stabilized soil, etc. on the construction site. The principle is to replace the volume of the excavated pit with the volume of a standard sand pile of uniform density to obtain the corresponding measurement index. [0003] The sand filling instrument usually includes a sand filling tube and a base plate. Put the base plate on the prepared test pit, align the holes on the base plate with the test pit, place the sand filling tube on the base plate, and put the standard sand from above the sand filling tube. Inject into the cylinder through the sand injection port, t...
