Manual compaction apparatus auxiliary device and manual compaction apparatus capable of positioning compaction position

Abstract

The invention discloses an auxiliary device of a manual compaction apparatus, the manual compaction apparatus comprises a base, a compaction cylinder is arranged on the base, a compaction hammer is arranged in the compaction cylinder, the compaction hammer is longitudinally sleeved with a compaction hammer guide cylinder, and the auxiliary device of the manual compaction apparatus comprises a positioning assembly, a clamping assembly and a supporting rod; the positioning assembly comprises a first cylinder, an angle index plate is arranged on the upper surface of the first cylinder, gradienters are arranged on the outer surfaces of the front side and the rear side of the first cylinder respectively, screws are arranged on the outer surfaces of the left side and the right side of the first cylinder respectively, and a transverse T-shaped sliding groove in the circumferential rotating direction is formed in the inner surface of the first cylinder. The clamping assembly comprises a second cylinder and two arc clamping pieces. T-shaped sliding blocks matched with the T-shaped sliding grooves are arranged on the outer surface of the second cylinder, and the supporting rod is connected with the base. The invention further discloses a manual compaction apparatus capable of positioning the compaction position. Compared with the prior art, all positions of the soil sample can be uniformly pressed in the real test process.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to an auxiliary device of a manual compaction instrument and a manual compaction instrument capable of locating a compaction position. Background technique [0002] The compaction instrument is a necessary testing equipment in highway, tunnel, hydropower and water conservancy, railway municipal and other projects. It is mainly used to measure the relationship between soil moisture content and dry density, and determine the optimum moisture content and maximum dry density of soil samples. , to evaluate the compaction performance of the soil. During the compaction test, it is necessary to use a compaction hammer to compact each layer of soil samples multiple times to ensure that each layer of soil samples is compacted evenly, thereby ensuring the accuracy of the compaction test results. At present, the inspectors subjectively determine the drop position of the compaction hammer each ...

AI Technical Summary

Problems solved by technology

At present, the inspectors subjectively determine the drop position of each compaction hammer during the operation process, resulting in excessive compaction in some positions of the soil sample and insufficient compaction in some positions

In addition, when the inspector manually holds the outer cylinder of the compacting hammer, the soil sample will be compacted unevenly due to the tilting and falling of the compacting hammer.

As a result, the compaction test results deviate from the real situation
