Description

Technical Field

[0001] The invention relates to the field of measurement, in particular to a pavement structure auditing measurement device for highway construction. Background Art

[0002] If the concrete does not meet the standards during the road paving process, it will cause road seepage. Road seepage will affect the roadbed below, causing the roadbed to collapse. Over time, it will cause the road surface to sag and eventually become damaged.

[0003] When accepting the highway pavement, an audit can be conducted at an appropriate location, so as to determine whether the structural quality of the pavement meets the requirements based on the audit of the pavement. When there are doubts about the pavement construction, the hidden works in question can be dug up for verification. The excavation method is more direct and easy to verify the truth of the problem, but the workload is large, so the sampling method is generally implemented. The verification is carried out by drilling for water seepage. When drilling, because the highway pavement contains concrete and the pavement is hard, the motor of the drill rod may burn out after drilling, and it is not convenient to replace the drill bit after it is worn, and the measurement effect is not very accurate.

[0012] Beneficial effects:

[0013] (1) The drilling mechanism is used to drill holes in the road surface that needs to be reviewed. One of the holes is used to fill water and the other is used to place the measuring assembly. When the drilling mechanism encounters a hard surface, the protective mechanism can protect the drilling mechanism when it is blocked and cannot continue to drill. The protective mechanism will separate from the drilling mechanism to ensure that the drilling mechanism will not continue to move downward after separation, thereby playing a protective role; the measuring assembly can measure the depth of water in the borehole into the ground, and then according to the depth of water in the borehole into the ground, the hardness and quality of the ground can be judged according to the time and depth of water infiltration into the ground; the water inlet mechanism can discharge water into the borehole, and after entering the borehole, the water will diffuse from the inner wall of the borehole to the surrounding areas; when the measuring mechanism drills downward, the water inlet mechanism starts to fill water, so that water enters the borehole; the driving mechanism can drive the drilling mechanism so that the drilling mechanism drills holes in the ground. The driving mechanism propels the drilling mechanism while driving the drilling mechanism, so that the drilling mechanism can drill holes in the road surface.

[0014] (2) When the drill rod is blocked by a hard road surface during drilling, in order to prevent the rod sleeve and the drill rod from being damaged during the downward movement, the protective mechanism is set to push the two rod sleeves apart during the upward movement, so that the two rod sleeves are separated from each other. The separation of the two rod sleeves drives the screw rod to separate synchronously. When the screw rod separates, the two driven wheels connected to the bottom of the screw rod are driven to separate. When the two driven wheels are separated from the driving wheel, the power of the driving wheel cannot be transmitted to the driven wheels. After the driven wheels are separated from the driving wheels, the driven wheels do not rotate, the driven wheels do not rotate, the screw rod does not rotate, the screw rod will not drive the driving mechanism to move downward through the protective mechanism, and then the rod sleeve set on the screw rod will not drive the protective mechanism to move downward. At this time, the drilling mechanism will no longer drill downward, thereby achieving the effect of protecting the drill rod.

[0015] (3) The guide seat is arranged to move up and down on the screw rod along with the rod sleeve. When the guide seat moves along with the rod sleeve, the first elastic member is stretched from a free state until the two rod sleeves drive the first connecting rod and the second connecting rod to rotate around the support plate, until the moment when the two driven wheels are just separated from the driving wheel, the first connecting rod and the second connecting rod just reach a horizontal position. At this time, the two ends of the first elastic member just move from the upper part to the lower part of the connection between the first connecting rod and the second connecting rod, and the first elastic member is still in a stretched state; at this time, under the action of the limit block, the first connecting rod and the second connecting rod will not flip over a large angle, thereby allowing the two ends of the first connecting rod and the second connecting rod to be unfolded, ensuring that the distance between the two screw rods during the unfolding process is large, so that the two driven wheels will not contact the driving wheel, thereby achieving a separated state.

When the two driven wheels 312 are separated from the driving wheel 34, the power of the driving wheel 34 cannot be transmitted to the driven wheels After the driving wheel 312 and the driven wheel 312 are separated from the driving wheel 34, the driven wheel 312 does not rotate, the driven wheel 312 does not rotate, the screw rod 38 does not rotate, and the screw rod 38 will not drive the driving mechanism 3 to move downward through the protective mechanism 2; when the connector 43 rotates with the sleeve 37, the connector 43 rotates and drives the drill rod 41 to rotate. When the drill rod 41 rotates, the spiral groove 42 arranged thereon rotates synchronously, and the drill hole has a spiral structure. The spiral groove 42 is convenient for discharging the concrete on the road surface during drilling; the spiral groove 42 can also realize the function of conveying water through the drilling hole when the water inlet mechanism 5 is filled with water; when the connector 43 is installed, the gasket 46 is pressed against the bottom of the driving mechanism 3, so that when the connector 43 is installed, the driving mechanism 3 and the connector 43 are completely sealed by the gasket 46; the water drainage groove 48 can be used to discharge water into the interior of the spiral groove 42 through the drainage hole 47, and then the water flow will flow from the interior of the spiral groove 42 into the interior of the drill hole.When the drill rod 41 cannot continue to drill downward, the rod sleeve 310 will transmit the force to the guide seat 23. When the guide seat 23 moves with the rod sleeve 310, the first elastic member 27 is stretched from the free state until the two rod sleeves 310 drive the first connecting rod 26 and the second connecting rod 28 to rotate around the support plate 311, until the two driven wheels 312 are just separated from the driving wheel 34, the first connecting rod 26 and the second connecting rod 28 just reach the horizontal position, at this time, the two ends of the first elastic member 27 just move from the upper part of the connection between the first connecting rod 26 and the second connecting rod 28 to the lower part, and the first elastic member 27 is still in a stretched state; at this time, under the action of the limit block 25, the first connecting rod 26 and the second connecting rod 28 will not flip over too large an angle, thereby making the first connecting rod 26 and the second connecting rod 28 not flip over too large an angle. Both ends of the first connecting rod 26 and the second connecting rod 28 are unfolded to ensure that the distance between the two screw rods 38 during the unfolding process is large, so that the two driven wheels 312 will not contact the driving wheel 34, thereby achieving a separated state; after the drill rod 41 has drilled two holes of different depths, the electric telescopic member 61 is started to extend downward, and when the electric telescopic member 61 moves downward, the electric telescopic member 61 drives the measuring instrument 62 to move downward. The measuring instrument 62 is preferably a laser measuring instrument 62. The laser measuring instrument 62 moves downward and enters the interior of the borehole. The depth of the borehole for placing the laser measuring instrument 62 is larger than the depth of the borehole for holding water, which can facilitate the measuring instrument 62 to measure downward leakage and lateral leakage, thereby judging whether the pavement structure meets the requirements.
