Problems solved by technology

However, the existing test soil tanks have the following problems: in different subgrade and pavement compaction tasks, the composition of the compaction medium material is not the same, and it is difficult to compare a certain type of road roller with a test soil tank that only lays one kind of compaction material Work performance on different compacted materials
To test the comprehensive operating performance of the road roller under different compaction materials, it is time-consuming and labor-intensive to dig up the soil tank and replace other compaction materials

Embodiment Construction

[0024] The present invention is described in further detail below in conjunction with accompanying drawing:

[0025] like figure 1 Shown is the test soil tank for the comprehensive test of road roller operation performance according to the present invention, including the foundation 7 .

[0026] Three sections of test areas are set on foundation 7, and an isolation area is set in the middle of each section of the test area; the three sections of test areas are respectively sand test area, graded crushed stone test area and graded soil test area, and the sand test area is paved with sand 1. Lay graded gravel 3 in the test area of ​​graded gravel, lay graded soil 4 in the test area of ​​graded soil, and lay other common compaction materials in each test area.

[0027] Sandy soil 1 includes particles with a particle size larger than 2mm and particles with a particle size larger than 0.075mm, the mass of particles with a particle size larger than 2mm is less than 50% of the total...

Abstract

The invention discloses a test soil bin for comprehensive test of working performance of a road roller. The test soil tank comprises a foundation, three test areas are arranged on the foundation, and an isolation area is arranged between every two each test areas; the three test areas are respectively a sandy soil test area, a graded broken stone test area and a graded soil test area; sandy soil is laid in the sandy soil test area; graded broken stone is laid in the graded broken stone test area; and graded soil is laid in the graded soil test area. Three different roadbed compaction materials are laid on the foundation, the isolation areas can block the compaction acting force between the different materials, the different compaction materials are prevented from being mixed during scarification, and therefore the comparability, repeatability and authenticity of a road roller test in the test soil tank are guaranteed.

Description

technical field [0001] The invention belongs to the field of road roller operation performance testing, and relates to a test soil tank for comprehensive testing of road roller operation performance. Background technique [0002] Road rollers are widely used in the construction of transportation infrastructure such as roads, railways, and airports. Their compaction capacity and compaction efficiency determine the speed of construction progress and the quality of the project, and are an important part of improving the durability of transportation infrastructure. At present, when road roller manufacturers mass-produce various types of road rollers, they need to test the operational performance of the prototypes in different subgrade and pavement compaction tasks. The operational performance test methods mainly include construction site tests and test soil tank tests. Due to the fact that the construction site test needs to arrange the test site during the construction process,...
