Description

Technical Field

[0001] The present application belongs to the technical field of road construction auxiliary equipment, and in particular, relates to a hole filling device for road coring holes and a construction method thereof. Background Art

[0002] In recent years, with the rapid development of the national economy, the construction of traffic roads has become one of the factors to measure the level of development of a city or region. Whether it is a highway or a general urban road, or a highway, with the gradual popularization and versatility of asphalt materials, the pavement structure of most roads uses asphalt materials as the pavement surface layer of the road. The flatness, permeability and construction convenience of asphalt roads make the current traffic road network use this type of material for construction and application. After the asphalt road construction is completed, it is necessary to conduct certain inspections on the structural layer of the road, and the road inspection method will inevitably use the corresponding core sampling method.

[0003] Road core sampling is a crucial testing method in road engineering and pavement maintenance. Coring testing of asphalt pavement is an important means to understand the internal structure and performance of the road. By observing and testing the core samples, key indicators such as the composition, density, porosity, and permeability of the asphalt mixture can be evaluated to determine whether the overall quality of the asphalt pavement meets the design requirements. This demand stems from the high attention paid to road safety, stability, and durability to ensure smooth traffic and driving safety. At the same time, through coring testing, the internal damage of the asphalt pavement can be intuitively observed, such as cracks, rutting, looseness, etc. These damages not only affect the performance of the road, but may also cause safety hazards.

[0004] Therefore, core sampling can determine the scope and extent of road maintenance, providing an important reference for the design and implementation of maintenance plans. However, the following problems often occur after existing core sampling:

[0005] 1. Generally, the holes left after coring on a road need to be filled with corresponding materials. If the hole filling cannot be completed in time, the coring holes on the road will be left without any treatment, leaving a large number of coring holes on the road surface.

[0006] 2. After conventional road coring, due to the large number of corings and the small size of individual coring materials, the required hole filling materials cannot be obtained in time, which requires more time and energy to purchase and transport materials, increasing processing costs.

[0007] 3. After coring of ordinary roads, construction workers cannot obtain materials corresponding to the road in time for filling holes, so they will use general concrete materials or mortar to fill holes. This will cause the filling of the holes after coring to be affected by different external temperatures or rolling pressures due to the use of different materials, resulting in greater damage to the road at that location.

[0008] 4. Since the holes after coring on the road cannot be filled in time, water is easily accumulated in the coring holes on the road when it rains. If the water accumulates for too long, coupled with the pressure from vehicles on the road, it may damage the internal structure of the road.

[0009] 5. If the holes left after road coring are not treated for a long time, the holes left behind may pose a dangerous threat to the daily travel of bicycle or electric vehicle users. Due to the existence of the holes, electric vehicles may bounce or deviate when passing through the holes quickly, causing traffic injuries. Summary of the invention

[0010] The present application provides a hole filling device for coring holes on a road and a construction method thereof, which solve the technical problem of how to quickly, timely and effectively fill and protect coring holes on a road.

[0011] In order to solve at least one of the above technical problems, the technical solution adopted in this application is:

[0014] A rotary adjustment assembly, comprising a plurality of sawtooth rods and a gear column, wherein the bottom of the gear column contacts the ball;

[0015] After the tooth segments of all the sawtooth rods pass through the outer cylinder and the inner cylinder in sequence, they directly mesh with the gear column passing through the inner cylinder; controlling the rotation of the gear column can drive all the sawtooth rods to rotate in the forward or reverse direction, and synchronously drive all the sawtooth rods to extend outward or contract inward, so that the outer ends of all the sawtooth rods are fixed against the inner wall of the hole or do not contact the hole.

[0016] Furthermore, there are four sawtooth rods, which are arranged at the same height on the annular cylinder, and the tails of the sawtooth rods are smooth surfaces.

[0017] Furthermore, the top of the annular cylinder is an annular closed surface, and a cover plate movably matched with the annular closed surface is also provided on the annular closed surface.

[0018] Furthermore, a ring gasket integrally constructed therewith is provided on the outer edge of the annular closed surface, and the outer extension of the ring gasket extends outwards and is suspended.

[0019] Furthermore, the top of the ring gasket is a downwardly inclined slope, and the slope of the slope is not greater than 10°.

[0020] Furthermore, the gear column includes a gear column and a connecting rod, and a hexagonal bolt hole is provided on the top of the connecting rod, which directly cooperates with the circular hole at the center of the cover plate, and the hexagonal bolt hole is fixed on the flange gasket on the connecting rod; the diameter of the flange gasket is larger than the diameter of the circular hole; the hexagonal bolt hole passes through the circular hole and makes the flange gasket contact with the lower end surface of the cover plate.

[0021] Furthermore, the bottom of the annular cylinder is a circular closed surface, the truncated cone and the inner cylinder are configured as a whole, and a stepped surface is also provided on the top of the truncated cone.

[0022] Furthermore, the ball is arranged at the center of the stepped surface, and can contact the bottom groove of the gear column; the connecting rod is controlled to rotate, so that the gear column can rotate along its axial direction.

[0023] Furthermore, the outer surfaces of the tooth columns are all straight tooth surfaces, which mesh with the straight teeth in the sawtooth rod, and their height is greater than the height of the straight teeth in the sawtooth rod.

[0024] A road coring hole filling construction method, using the hole filling device as described above, comprises the following steps:

[0025] S1. Construction personnel measure the size of the coring hole in the road, and select the outer cylinder of the annular cylinder that can fit the hole based on the hole size;

[0026] S2, select the inner cylinder with the same diameter as the truncated cone and make its height the same as that of the outer cylinder, prepare the circular closed surface at the bottom of the annular cylinder and the annular closed surface at the top, connect the inner cylinder and the outer cylinder together, and arrange the ball at the top of the truncated cone;

[0027] S3, sequentially preparing through holes for the sawtooth rod to pass through on the wall surfaces of the inner tube and the outer tube and installing the sawtooth rod on the walls of the inner tube and the outer tube;

[0030] S6. When the hole needs to be filled with plugging material, the hexagonal bolt hole needs to be controlled to rotate in the opposite direction by the hexagonal bolt wrench, so that the gear column drives all the sawtooth rods to move inward. When all the sawtooth rods are no longer in contact with the inner wall of the hole, the hole filling device is directly pulled out of the hole as a whole, and the hole can be filled with material;

[0031] S7, repeating steps S5-S6, and continuing to use the pulled-out hole filling device to protect the next hole.

[0041] 21. Sawtooth rod 22. Gear column 23. Hexagonal bolt hole DETAILED DESCRIPTION

[0042] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] This embodiment provides a hole filling device for coring holes in roads, such as Figure 1 As shown, it includes an annular cylinder 10 with a hollow structure and a rotary adjustment component 20 for adjusting the contact with the hole. The annular cylinder 10 includes an outer cylinder and an inner cylinder, and a truncated cone 11 is provided at the bottom of the inner cylinder, and a freely rotatable ball 12 is provided on the top of the truncated cone 11. The rotary adjustment component 20 includes a plurality of sawtooth rods 21 and a gear column 22, and the bottom of the gear column 22 is in contact with the ball 12. After the tooth segments of all sawtooth rods 21 pass through the outer cylinder and the inner cylinder in sequence, they directly mesh with the tooth columns of the gear column 22 passing through the inner cylinder; controlling the rotation of the gear column 22 can drive all the sawtooth rods 21 in the forward direction, so as to synchronously drive all the sawtooth rods 21 to extend outward, so that the outer ends of all the sawtooth rods 21 are fixed against the inner wall of the hole. Alternatively, the control gear column 22 can rotate to drive all the sawtooth rods to rotate in the opposite direction, so as to synchronously drive all the sawtooth rods 21 to retract inward, so that the outer ends of all the sawtooth rods 21 are away from the inner wall of the hole and do not contact the hole, thereby loosening the hole filling device and taking the hole filling device out of the hole as a whole.

[0044] like Figure 2 As shown, the bottom of the annular cylinder 10 is a circular closed surface, through which the inner cylinder and the outer cylinder can be fixed as one. The top of the annular cylinder 10 is an annular closed surface, through which the inner cylinder and the outer cylinder can be connected together to form a hollow cylinder structure.

[0045] Furthermore, a cover plate 13 is provided on the annular closed surface and is movably matched with the inner edge of the annular closed surface. A circular hole is provided in the center of the cover plate 13, which can just allow the connecting rod of the gear rod column 22 to pass through and be firmly embedded in the cover plate 13. At the same time, the cover plate 13 is also provided with a plurality of cross-shaped bolt fixing holes to fix the cover plate on the annular closed surface.

[0046] At the same time, a ring gasket 14 integrally constructed therewith is provided at the outer edge of the annular closed surface, and the outer extension of the ring gasket 14 is suspended outward. Preferably, the top of the ring gasket 14 is a downwardly inclined slope with a slope of no more than 10°, mainly to facilitate the unobstructed passage of passing vehicles, which can not only protect the top of the hole filling device, but also protect the edge structure of the hole.

[0047] like Figure 3 As shown, the truncated cone 11 and the inner tube are integrally configured, and a stepped surface is provided on the top of the truncated cone 11, mainly for placing the ball 12, and also forming a space with the outer circular edge of the truncated cone 11 to avoid interference between the serrated rod 21 and the outer circular edge of the truncated cone 11.

[0048] like Figure 4As shown, the ball 12 is embedded at the center of the stepped surface of the truncated table 11, and can contact the bottom surface groove of the gear column 22. The connecting rod on the gear column 22 is controlled to rotate, so that the gear column of the gear column 22 can rotate along its axial direction.

[0049] The gear column 22 includes a gear column and a connecting rod, and a hexagonal bolt hole 23 is provided on the top of the connecting rod, which directly passes through the circular hole of the cover plate 13. The hexagonal bolt hole 23 is welded to the flange gasket on the top of the connecting rod, and the diameter of the flange gasket is larger than the diameter of the circular hole. When matched, the hexagonal bolt hole 23 passes through the circular hole and makes the flange gasket directly contact the lower end surface of the cover plate 13.

[0050] like Figure 5 As shown, there are four sawtooth rods 21, which are arranged at the same height on the annular cylinder 10, and the tail of the sawtooth rod 21 is a smooth surface, and the end close to the inner cylinder is a straight tooth section, and all the straight teeth are vertically arranged along the height of the inner side surface, which directly meshes with the outer surface of the tooth column. In order to ensure the safety and stability of gear meshing, the height of the gear surface in the tooth column is required to be 1-1.5 times the height of the straight teeth in the sawtooth rod 21. Preferably, the height of the gear surface in the tooth column is required to be 1.2 times the height of the straight teeth in the sawtooth rod 21. This is because if the height of the tooth column is more than 1.5 times the height of the straight teeth in the sawtooth rod 21, during the gear meshing process, the straight teeth will slide up and down along the height direction of the tooth column. If the height of the tooth column is less than the height of the straight teeth in the sawtooth rod 21, the sawtooth rod 21 cannot be stably driven to mesh, which directly affects the working state of the sawtooth rod 21.

[0051] The components and materials used in the entire hole filling device are easy to obtain and can be directly processed through existing materials on the construction site. The device can also be assembled by using simple materials without spending too much material and processing. The entire hole filling device has a simple structure and is easy to operate. It has better protection for the holes and can provide a closed protection for the hole position, which can effectively prevent debris and garbage from falling into the holes, avoiding the trouble of difficult cleaning later.

[0052] The overall safety performance is higher. The hole filling device can better protect the holes after coring in the road effectively and safely, ensuring the consistency of the flatness of the road surface, so that passing electric vehicles and bicycles do not have to fall there due to unfilled holes, avoiding safety accidents.

[0053] The entire construction process can be completed by rotating the gear column 22 using a hexagonal bolt wrench, so that the gear column 22 drives the sawtooth rod 21 meshing with it to rotate, and the hole filling device is fixed in the core hole. The hole filling device is easy to operate, and a single person can complete the construction and installation operation. It has a good hole filling protection effect, can be reused many times, is green and environmentally friendly, and has no attached pollutants. Not only is the hole filling protection efficient and has a good protection quality effect; but also when the hole does not need to be protected and filled, it can be pulled out of the hole by reverse rotation and reused.

[0054] A road coring hole filling construction method, using the hole filling device as described above, comprises the following steps:

[0055] S1. Construction personnel measure the size of the coring hole in the road, and select the outer cylinder of the annular cylinder 10 that can fit the hole based on the hole size.

[0056] S2, select an inner cylinder with the same diameter as the truncated cone 11 and make the height of the inner cylinder the same as that of the outer cylinder, and prepare a circular closed surface structure at the bottom of the annular cylinder column 10 and an annular closed surface structure at the top. And the inner cylinder and the outer cylinder are fixed on the same bottom surface through the circular closed surface. Then the inner cylinder and the outer cylinder are connected together through the annular closed surface, and an inclined ring pad 14 made by processing with it is also provided on the outer edge of the annular closed surface, and its slope surface is convenient for passing vehicles to pass up and down without hindrance, which can not only protect the top of the hole filling device, but also protect the edge structure of the hole. At the same time, a ball 12 for supporting the gear column 22 and facilitating the rotation of the gear column 22 is arranged on the top of the truncated cone 11.

[0057] S3. Through holes for four sawtooth rods 21 to pass through are prepared in sequence on the wall surfaces of the inner cylinder and the outer cylinder, and the four sawtooth rods 21 are mounted on the walls of the inner cylinder and the outer cylinder; at the same time, the straight tooth sections of the four sawtooth rods 21 enclose a regular quadrilateral space to facilitate meshing with the gear column 22.

[0058] S4, the gear column in the control gear column 22 is vertically inserted into the inner cylinder and directly meshes with the straight teeth on all the sawtooth rods 21; a cover plate 13 for stabilizing the gear column 22 is provided on the top of the outer cylinder, and a circular hole is provided in the center of the cover plate through which the hexagonal bolt hole 23 on the top of the gear column 22 passes, so that the entire coring and hole filling device is constructed as a closed structure.

[0059] S5. Insert the hole filling device into the hole in the road, and use a hexagonal bolt wrench to rotate the hexagonal bolt hole 23 clockwise to drive the gear column 22 to rotate clockwise. The gear column 22 is suspended by the ball 12 and can move outward along its own axis and drive all the sawtooth rods 21 synchronously until the outer ends of all the sawtooth rods 21 hit the inner wall of the hole, thereby fixing the hole filling device in the hole.

[0060] S6. When the hole needs to be filled with sealing material, the hexagonal bolt hole 23 must be controlled to rotate in the opposite direction by the hexagonal bolt wrench so that the gear column 22 drives all the serrated rods 21 to move inward. When all the serrated rods 21 are no longer in contact with the inner wall of the hole, the hole filling device can be directly pulled out of the hole as a whole to fill the hole with material.

[0061] S7, repeating steps S5-S6, and continuing to use the pulled-out hole filling device to protect the next hole.

[0062] The hole filling device for coring holes in roads designed by the present application has a simple structure and is easy to operate. It can quickly and accurately close and protect the holes, can be firmly fixed in the holes, and integrated with the surrounding road surface to ensure the flatness and consistency of the road surface. At the same time, it can effectively protect the hole structure without affecting normal walking; it is safe and efficient to operate, can also be taken out in reverse, and can be reused. The present application also proposes a construction method using the hole filling device.

[0063] The above detailed description of the embodiments of the present application is only a preferred embodiment of the present application and cannot be considered to limit the scope of implementation of the present application. All equivalent changes and improvements made within the scope of the present application should still fall within the scope of the patent coverage of the present application.
