Description

Novel roadbed pavement loose paving thickness detection device

Technical Field

The invention relates to the technical field of roadbed and pavement construction, in particular to a novel roadbed and pavement loose paving thickness detection device.

Background

At present, in the field of roadbed construction, when loose pavement thickness is detected, manual pit digging detection is often adopted, the detection method needs a specially-assigned person for charge, a large amount of human resources are consumed, the efficiency is low, the project progress is often influenced during large-area construction, meanwhile, the detection method is poor in precision, the artificial factor of loose pavement thickness control is large, the elevation and the compaction thickness of each layer cannot be guaranteed, and certain influence can be generated on the project quality. In the field of pavement construction, when the loose pavement thickness is detected, the steel rod is often matched with the steel ruler for detection, two tools are needed in the detection method, detection personnel need to bow every detection, the intersection surface of the top of a detection position and the steel rod is manually controlled, the workload of the detection personnel is large, inconvenience is brought to site construction, meanwhile, the precision is poor, the human error is large, the loose pavement thickness is not tightly controlled, the elevation and the compaction thickness of each layer cannot be guaranteed, and certain influence can be generated on the engineering quality.

The utility model discloses a current application number CN 202020147716.5's utility model discloses a roadbed structure layer thickness check out test set.

Although the utility model discloses a some problems have been solved, still have following scheduling problem to solve when using:

the utility model discloses a measurement mode that adopts the pointer scale causes the number of degrees inaccuracy because of reasons such as the pointer is crooked easily when measuring roadbed structure layer thickness, and then has influenced measuring precision.

Therefore, the applicant inherits the experience of abundant design development and actual manufacturing of the related industry for many years, researches and improves the existing structure and deficiency, and provides a novel roadbed pavement loose thickness detection device so as to achieve the aim of higher practical value.

Technical problem to be solved

Aiming at the defects of the prior art, the invention provides a novel roadbed pavement loose thickness detection device, which solves the comprehensive problems that manual excavation detection consumes a large amount of human resources, the efficiency is low, the project progress is often influenced during large-area construction, meanwhile, the detection method has poor precision, the artificial factor of loose thickness control is large, the elevation and the compaction thickness of each layer cannot be ensured, and the project quality is influenced to a certain extent.

(II) technical scheme

In order to achieve the purpose, the invention is realized by the following technical scheme: the utility model provides a novel roadbed pavement loose thickness detection device, includes drill rod, annular fixing device, three-dimensional needle carving pipe, both ends are provided with upper end packing ring and lower extreme packing ring respectively about three-dimensional needle carving pipe, be provided with annular fixing device between upper end packing ring and the lower extreme packing ring, annular fixing device cover is established on three-dimensional needle carving pipe, the last unified centre of a circle and radius and the round hole of all having seted up of upper end packing ring, lower extreme packing ring and annular fixing device, the round hole interpolation has the drill rod, be provided with the scale on the drill rod.

Preferably, a handle is arranged at the upper end of the steel chisel.

Preferably, the steel chisel is in transition fit with the upper end gasket, the lower end gasket and the annular fixing device.

Preferably, the three-dimensional needle-carving tubes are in interference fit with the upper end gasket, the lower end gasket and the annular fixing device.

(III) advantageous effects

The invention provides a novel device for detecting the loose pavement thickness of a roadbed pavement. The method has the following beneficial effects:

this novel roadbed road surface loose thickness detection device utilize simple device, from convenient, practical, automatic angle design, through practice testings, this kind of device is both convenient, practical, and degree of automation is high, and the precision is high simultaneously, has reduced the human error in the testing process, has avoided loose thickness control not tight, causes roadbed road surface elevation and compaction thickness not to satisfy design and standard requirement, seriously influences roadbed road surface's quality.
