Example Embodiment

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

[0028] Refer to figure 1 The present invention provides a water-absorbing device for core-drilling sampling on asphalt pavements and a method of use thereof. The entire water-absorbing device is sleeved on the outside of the core drill bit and placed on the road surface, and the core-drilling machine is turned on for core sampling. During the sampling process, the sleeve can block the water splashed by the drill bit, and the water is absorbed by the water absorption layer without polluting the road surface. After the sampling is completed, the water absorption device is removed, and the extruding part is pulled outward so that the extruding part approaches the inner wall of the sleeve. Move and squeeze the water-absorbing layer in the direction of, thereby squeezing out the water in the water-absorbing layer, which can be used again, which solves the problem of...

Abstract

The invention relates to a water absorbing device for core drilling sampling of a bituminous pavement. The device comprises a sleeve, an extrusion part, a water absorbing layer and a traction member;the extrusion part is installed in the sleeve and can stretch and contract in an elastic way, certain distance is set between the extrusion part and the inner wall of the sleeve to form an installation space, and a space that can be penetrated by a drill bit of a core drilling device is formed inside the extrusion part; the water absorbing layer is filled into the installation space, the bottom side of the water absorbing layer is leveled with that of the sleeve, and the water absorbing layer absorbs water generated when the drill bit drills a core for sampling; and the traction member is fixedly arranged in the extrusion part and stretches outside by penetrating the sidewall of the sleeve, the traction member is drawn outwards to pull the extrusion part to deform towards the inner wall ofthe sleeve and extrude the water absorbing layer, and thus, water in the water absorbing layer is extruded out. The problem that water of the drill bit splashes is solved effectively, water of the drill bit is avoided from polluting the pavement, the trouble of cleaning later is omitted, the construction safety is ensured, and the construction efficiency is enhanced.

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 ...
