Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] refer to figure 1 , the present invention provides a water absorbing device for asphalt pavement core sampling and its use method, by putting the whole water absorbing device on the outside of the drill bit of the core drilling machine and placing it on the road surface, and then turning on the core drilling machine for core sampling, During the sampling process, the sleeve can block the water splashed by the drill bit, and then the water is absorbed by the water-absorbing layer without polluting the road surface. After the sampling is completed, remove the water-absorbing device and pull the extruded part outward so that the extruded part is close to the inner wall of the sleeve Move in the direction of the water-absorbing layer and squeeze the water-absorbing layer, so as to squeeze out the water in the water-absorbing layer, which can...

Abstract

The invention relates to a water-absorbing device for core sampling of asphalt pavement, which comprises: a sleeve; an extruding part installed in the sleeve and elastically stretchable; Enclosed to form an installation space, and the interior of the extruded part forms a space for the drill bit of the core drilling machine to pass through; the water-absorbing layer filled in the installation space, and the bottom surface of the water-absorbing layer is flush with the bottom surface of the sleeve, passing through the water-absorbing layer Absorb the water generated when the drill core is sampled; and the traction part fixed on the extrusion part and protruding outward through the side wall of the sleeve, by pulling the traction part outward, the extrusion part is pulled toward the inner wall of the sleeve The direction deforms and squeezes the water-absorbing layer, thereby squeezing out the moisture in the water-absorbing layer. The invention effectively solves the problem that the water of the drill bit splashes everywhere, and prevents the water from the drill bit from polluting the road surface, reduces the trouble of later cleaning, ensures the construction safety, and improves the construction efficiency.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a water-absorbing device for core sampling of asphalt pavement and a method for using the same. Background technique [0002] When doing the asphalt pavement compaction test, it is necessary to sample the drill core of the asphalt pavement. When the drill core is sampled, the drill core machine needs to add water to wet the drill bit. Therefore, when the drill bit rotates rapidly, the water from the drill bit is easy to splash on the operator. And because the asphalt concrete pavement is an impermeable pavement, the water of the drill core will pollute the asphalt concrete pavement, which will cause trouble for later stage cleaning. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, to provide a water absorbing device for asphalt pavement drilling core sampling and its use method, which solves the problem of ...
