Description

Technical Field

[0001] The utility model belongs to the technical field of asphalt pavement detection, and in particular relates to a water seepage detection device for asphalt pavement construction. Background Art

[0002] One of the basic points of asphalt pavement construction is that the asphalt layer can basically block the infiltration of rainwater. If there is at least one impermeable layer in the asphalt surface layer and the surface layer is permeable, the surface water can infiltrate in time without forming a water film, thus improving the anti-skid performance and reducing noise. After the asphalt pavement construction is completed, the water permeability coefficient of the pavement needs to be tested. The water permeability coefficient of the asphalt pavement is generally tested by a pavement water permeability detection device. During the operation, the cleaned pavement will be marked with a circle according to the size of the base of the detection device with chalk; a layer of sealing material is spread on the pavement along the circle of the base, and pressed by hand while applying, so that the sealing material fills the gap and is firmly bonded to the pavement. The diameter of the sealing material circle is the same as the diameter of the base. The base is pressed hard on the pavement sealing material circle, and a heavy iron ring is added to press the base to prevent the pressurized water from flowing out between the base and the pavement.

[0003] The existing pavement water seepage detection device has the following problems when performing the above operation: 1. It is necessary to draw a circle in advance with chalk, and it is easy to apply the sealing material beyond the inner circle when applying the sealing material, and the excess part needs to be wiped off, which makes the steps more cumbersome and troublesome, resulting in low efficiency; 2. When the base is pressed on the sealing material, manual visual judgment will also cause the base to be easily offset, and the center of the base cannot be aligned with the center of the sealing material ring, which will easily affect the sealing effect. Utility Model Content

[0004] The utility model provides a water seepage detection device for asphalt pavement construction, which solves the problems of needing to draw a circle in advance with chalk, and easily smearing the sealing material beyond the inner circle when applying the sealing material, and needing to wipe off the excess part, thereby making the steps more cumbersome and troublesome, resulting in low efficiency, and when the base is pressed on the sealing material, manual visual judgment will also cause the base to be easily offset, and then the center of the base cannot be aligned with the center of the sealing material ring, thereby easily affecting the sealing effect.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a device for detecting water seepage in asphalt pavement construction, comprising a detection device body, a base is arranged at the bottom of the detection device body, three columns are evenly fixed upward on the top surface of the base on the circumference, a ring cover is arranged on the periphery of the base, the ring cover comprises a surrounding plate located on the periphery of the base and a top ring plate arranged parallel to the upper side of the base, the surrounding plate and the top ring plate are integrally formed, and the top end of the surrounding plate is connected to the outer end of the top ring plate, the inner side wall diameter of the top ring plate is smaller than the outer side wall diameter of the base, the top ring plate is evenly arranged with three waist-shaped holes on the circumference, each of the columns passes through a waist-shaped hole, and each A card slot is respectively arranged on the side wall of the top and bottom ends of the column facing the axis of the base, and the two ends of each waist-shaped hole are of different sizes. The end with a larger size of the waist-shaped hole only matches the size of the outer wall of the column, and the end with a smaller size of the waist-shaped hole matches the size of the inner wall of the card slot and the size of the outer wall of the column. Three through holes are evenly arranged on the circumference of the ring cover, and a fixing column is vertically penetrated in each of the through holes. A horizontally arranged extrusion plate is commonly fixed downward at the bottom ends of the three fixing columns, and the extrusion plate is located between the outer wall of the base and the inner wall of the enclosure plate. A horizontally arranged load-bearing plate is commonly fixed upward at the top ends of several of the fixing columns.

[0006] The beneficial effects of the utility model are as follows: after the ring cover is lifted up so that the top ring plate is aligned with the position of the slot on the upper side, the entire ring cover is rotated, and the inner wall of the small-sized end of the waist-shaped hole is engaged with the slot, and then the column supports the top ring plate at the height position of the slot, so that the outer wall of the base is not blocked, and then the sealing material is simply applied along the outer wall of the base, and then the ring cover is reversed to make the inner wall of the waist-shaped hole separate from the slot, and then the fixation of the height of the ring cover is released, and the ring cover is driven to move downward so that the bottom end of the enclosure falls on the road surface outside the sealing material. , and rotate the ring cover, and then limit the height of the ring cover through the groove on the lower side to keep the bottom end of the enclosure against the road surface, and then press down the load-bearing plate, thereby driving the extrusion plate to press the sealing material downward. The sealing material is subject to the extrusion force and the restrictions of the base and the enclosure, and will eventually evenly cover and fill the gaps and firmly bond to the annular road surface between the base and the enclosure. It is no longer necessary to manually align the base with the center of the sealing material ring to avoid mistakes. In addition, the coating range of the sealing material applied in the above manner is more precise, and the coating steps are simpler, easier and more efficient.

[0011] As a further improvement of the above technical solution: the limit covers are all threadedly connected to the top ends of the columns.

[0012] The beneficial effect of this improvement is that the limit cover and the column are threadedly connected, which makes it easy to remove the limit cover, and then the ring cover can be installed on the column or removed from the column.

[0013] To facilitate operation of lifting or rotating the ring cover;

[0014] As a further improvement of the above technical solution: the diameter of the outer wall of the bearing plate is larger than the diameter of the outer wall of the ring cover.

[0015] The beneficial effect of this improvement is that the outer edge of the load-bearing plate extends outward beyond the ring cover, making it easy to pinch the outer edge of the load-bearing plate, and drive the fixed column and the extrusion plate through the load-bearing plate, and then drive the ring cover to rise, fall or rotate through the fixed column and the extrusion plate.

[0016] In order to better compress all the sealing materials through the extrusion plate and prevent water from easily seeping out along the outer wall of the base;

[0017] As a further improvement of the above technical solution: a horizontally arranged bottom ring is fixed to the periphery of the bottom end of the base, the radial dimension of the bottom ring is much smaller than the radial spacing between the bottom ring and the enclosure, a sealing ring is installed on the inner side of the extrusion plate, the sealing ring abuts against the outer side wall of the base, and the outer side wall of the extrusion plate abuts against the inner side wall of the enclosure.

[0018] The beneficial effect of this improvement is that the upper and lower layers of the space between the base and the enclosure are completely separated by the extrusion plate and the sealing ring, so that when the sealing material is pressed down by the extrusion plate, it can be completely confined in the lower space, which is more conducive to pressing all the sealing materials downward. The inner peripheral part of the compressed sealing material will cover the bottom ring, and cooperate with the sealing effect of the sealing ring to effectively prevent water from seeping out along the outer wall of the base.

[0019] In order to better press the sealing material downward;

[0020] As a further improvement of the above technical solution: two counterweights are placed on the top surface of the bearing plate, and the two counterweights are both semicircular and spliced ​​with each other.

[0021] The beneficial effect of this improvement is that two semicircular counterweights are placed on the load-bearing plate and spliced ​​together to form a complete circular ring, and the sealing material can be pressed downward more easily by the deadweight of the counterweights.

[0022] In order to stably place the counterweight on the bearing plate, it is prevented that the counterweight is easily offset by force during the process of pressing down the bearing plate, resulting in gradual separation from the bearing plate;

[0023] As a further improvement of the above technical solution: an insert block is fixed upwardly on the load-bearing plate corresponding to each counterweight block, and the insert block is plugged into the bottom of the counterweight block.

[0024] The beneficial effect of this improvement is that the two counterweight blocks are each plugged into an insert block and assembled with each other, and the counterweight block can be stably placed on the load-bearing plate through the insert block, avoiding the problem that the counterweight block is easily displaced by force during the process of pressing down the load-bearing plate and gradually detaches from the load-bearing plate.
