Embodiment Construction

[0023] Soil relative density meter of the present invention, comprises such as figure 1 The shown compacting cylinder 1 and the hammer 2 matched with the compacting cylinder 1, (since the positional relationship between the hammer 2 and the compacting cylinder 1 is the prior art, in order to highlight the improvement point of the present invention - compaction Cylinder 1, the drawing omits the expression of the hammer 2, so it is not shown) The compaction cylinder 1 includes a bottom plate 11, a main cylinder 12 and a casing 13, and the main cylinder 12 and the casing 13 are non-detachable and fixed connected, the bottom plate 11 is non-detachably fixedly connected to the bottom end of the main cylinder 12 .

[0024] Preferably, the bottom plate 11 and the main cylinder 12 and the main cylinder 12 and the casing 13 are integrally formed.

[0025] Of course, the bottom plate 11 and the main cylinder 12, and the main cylinder 12 and the casing 13 can also be fixedly connected b...

Abstract

The invention discloses a soil relative density meter, comprising a compaction cylinder (1) and a hammer (2), wherein the compaction cylinder (1) comprises a bottom plate (11), a main cylinder (12) and a protective cylinder (13), the main cylinder (12) and the protective cylinder (13) are fixedly connected in a non-removable manner, and the bottom plate (11) and the bottom end of the main cylinder(12) are fixedly connected in a non-removable manner. The soil relative density meter disclosed by the invention is small in test error, high in success rate and simple and reliable to operate.

Description

technical field [0001] The invention belongs to the technical field of soil density measuring equipment, in particular to a soil relative density meter with small test error, high success rate, simple and reliable operation. Background technique [0002] The soil relative density meter is used to measure the maximum and minimum void ratio of aggregated soil, thereby estimating the relative density of the soil, thereby evaluating the durability of the road base layer, filling or other construction objects. [0003] Existing soil relative density meter generally comprises compacting cylinder and hammer as described in Chinese utility model patent "soil relative density meter" (application number: 201621443267.9, publication date: 2017.8.1). The structure of the compaction cylinder is as described in the Chinese utility model patent "an improved compaction cylinder for relative density meter" (application number: 201721399975.1, publication date: 2018.5.1), including the bottom...
