Description

Highway bridge compactness detection device

Technical Field

The utility model relates to a detection device technical field specifically is a highway bridge compactness detection device.

Background

Compaction, also known as compaction, refers to the ratio of the dry density of soil or other road material after compaction to the standard maximum dry density, expressed as a percentage. The compaction quality of the roadbed and the road surface is one of the most important internal indexes for the construction quality management of road engineering. The strength, rigidity, stability and flatness of the roadbed and the pavement can be ensured only by fully compacting the roadbed and the pavement structure layer, so that the service life of the roadbed and the pavement is prolonged. The field compaction quality of the roadbed pavement is expressed by the degree of compaction. For roadbed soil and pavement base, the compactness refers to the ratio of the dry density actually achieved by a construction site to the maximum dry density obtained by an indoor standard compaction test; for asphalt pavement, it refers to the ratio of the density actually achieved on site to the indoor standard density.

The determination of the degree of compaction mainly comprises indoor standard density (maximum dry density) determination and field density test. The compactness of the roadbed reflects the compact strength of each compacted layer of the roadbed, and the overall strength, stability and durability of the roadbed can meet the requirements only if the compact strength of each compacted layer meets the requirements. If the layer is not qualified in compactness, the whole strength, stability and durability of the roadbed are affected, and the reworking treatment is carried out at the moment, so that waste is caused, the construction progress is seriously affected, and the construction period is delayed. In order to ensure that the overall strength, stability and durability of the roadbed meet the requirements, the highway roadbed construction technical specification (JTG F10-2006) provides that: in the construction process of the roadbed, the compaction degree of each compacted layer needs to be checked, the upper layer can be filled after the compaction degree is qualified, otherwise, the reason needs to be found out, and measures are taken for pressure compensation.

The compaction degree of the existing prop bridge needs to be detected after construction is completed, and the effect of the existing detection device is not good enough and is difficult to accurately measure.
