Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a road surface core sampling and pollution prevention device. Background Technology

[0002] When testing the compaction degree and structural layer thickness of asphalt pavement, core drilling is commonly used to obtain core samples of the structural layer. The core drilling operation is as follows: The core drilling machine is placed flat on the road surface, and the asphalt pavement structural layer is ground by a high-speed rotating drill bit to obtain a core sample. During this process, water needs to be continuously supplied to cool the drill bit and to wash away the mixture residue and powder removed during drilling. The mixture residue and powder mix with water to form a slurry that flows onto the asphalt pavement. At the same time, the high-speed rotating drill bit also splashes out slurry.

[0003] When core drilling is used to sample asphalt pavement, the slurry discharged from the drilling machine can easily contaminate the newly paved asphalt surface. After drilling, the contamination needs to be cleaned up, which is not environmentally friendly and increases the workload. Traditional core drilling leaves the newly paved asphalt pavement covered with slurry, causing large-scale pollution. This requires a lot of manpower and water for cleaning, which is neither energy-efficient nor environmentally friendly.

[0004] Currently, the slurry generated from core drilling operations on asphalt pavements is generally treated by manual or water truck washing, which is inefficient, wastes a lot of water resources, and causes water pollution.

[0005] In summary, there is an urgent need for an asphalt pavement core drilling and pollution prevention device to solve the problems existing in the current technology. Utility Model Content

[0006] This invention addresses the problem of slurry spillage during road core sampling, which contaminates newly paved asphalt pavements. Manual cleaning after drilling is necessary, resulting in low overall sampling efficiency. Alternatively, water truck washing can waste water resources. Therefore, this invention proposes a road core sampling anti-contamination device. This device uses a sleeve to prevent slurry splashing, absorbent material to prevent slurry leakage, and a sealing ring to prevent slurry seepage, thus effectively preventing slurry from contaminating the newly paved asphalt pavement.

[0007] The technical solution adopted is as follows:

[0008] A road surface core sampling and pollution prevention device includes:

[0009] The sleeve is a cylindrical shape with openings at the top and bottom, and is vertically arranged on the outer periphery of the road surface core sampling area;

[0010] A water-absorbing material having through holes, the water-absorbing material being laid on the road surface around the outer periphery of the sleeve through the through holes;

[0011] A drain pipe, connected to the inside of the sleeve, is used to drain the sludge accumulated inside the sleeve;

[0012] A sealing ring is disposed between the through hole of the absorbent material and the outer wall of the sleeve.

[0013] Optionally, an annular groove is machined on the outer wall of the sleeve, and the sealing ring is installed in the annular groove.

[0014] Optionally, the absorbent material is a sponge.

[0015] Optionally, a weighted strip is provided on the upper edge of the absorbent material.

[0016] Optionally, the weight bar is an iron bar.

[0017] Optionally, a sealing gasket is provided on the underside of the edge of the absorbent material.

[0018] Optionally, the diameter of the sleeve gradually decreases from the lower opening to the upper opening.

[0019] Optionally, a container may also be included for holding the sludge flowing from the drain pipe.

[0020] This utility model has the following beneficial effects:

[0021] (1) The drain pipe of this application discharges the slurry generated during the core drilling process in a concentrated manner. When the slurry reaches a certain height, it flows out from the drain pipe, saving time and effort. The container collects the slurry in the drain pipe, which is convenient for centralized treatment.

[0022] (2) The water-absorbing material of this application absorbs the slurry in the bottom area of ​​the drill core, so that the drilling area still needs to be cleaned after the drill core is moved; the water-absorbing material absorbs the slurry generated by the drill core in a timely manner, so as to prevent the slurry from splashing and flowing on the ground, and can effectively prevent road pollution.

[0023] (3) The sealing ring of this application effectively seals the slurry in the core drilling area, preventing some of the slurry in the absorbent material from flowing out, and can effectively prevent road pollution.

[0024] (4) The height of the drain pipe in this application is 20mm from the bottom of the sleeve, and the height of the absorbent material is 50mm. This maximizes the storage and centralized discharge of sludge, while also taking into account the absorbent material's ability to absorb sludge.

[0025] (5) The diameter of the protective sleeve of this application is 220mm and the height is 150mm, which effectively takes into account the size of the drill bit and the convenience of personnel operation. Attached Figure Description

Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims. Furthermore, in this specification, the drawings are not drawn to scale, and the same reference numerals denote the same parts.

For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. "Rotary connection" refers to a connection where the components can rotate relative to each other after connection. The directional terms mentioned in the embodiments of this application, such as "upper," "lower," "inner," and "outer," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0032] This application provides a road core sampling pollution prevention device, including a sleeve 10 for covering the outer periphery of the drill bit to prevent slurry from splashing; absorbent material 20 laid on the road surface around the sleeve 10 to absorb slurry flowing out from the gap between the sleeve 10 and the road surface; a drain pipe 30 connected to the inside of the sleeve for draining the slurry accumulated inside the sleeve 10; and a container for holding the slurry flowing out from the drain pipe.

[0033] The sleeve 10 is a hollow cylindrical shape, not closed at the top and bottom, and is vertically arranged on the outer periphery of the road surface coring area, which is the area where the drill bit will drill to extract cores. The sleeve can be made of stainless steel or steel. The sleeve 10 is arranged on the outer periphery of the road surface coring area, that is, it can cover the outer periphery of the drill bit. The bottom of the sleeve 10 contacts the road surface, covering the road surface coring area within the sleeve 10. The upper end of the sleeve 10 is open for the drill bit to extend into it. The drill bit extends into the sleeve 10 from the upper end, thus making contact with the ground. By rotating the drill bit, cores can be extracted from the ground. The drill bit is an annular coring drill bit, which can cut a circular core from the road surface. The specific structure and operation of the coring drill bit are not discussed here.

[0034] Preferably, the sleeve has a diameter of 220 mm and a height of 150 mm to accommodate most drill bit models.

[0035] A drain pipe 30 is provided on the side wall of the sleeve 10. One end of the drain pipe 30 is connected to the inside of the sleeve 10, and the other end can be connected to a flexible hose, which is connected to a container. During the drilling process, coolant needs to be sprayed onto the drill bit to cool it. This coolant, along with the mixed slag and powder removed during the core flushing process, forms a slurry when mixed with water. The slurry accumulates and rises continuously inside the sleeve 10. When it reaches the height of the drain pipe 30, it enters the flexible hose from the drain pipe 30 and then flows into the container through the hose.

[0036] The absorbent material 20 may be plate-shaped with through holes 201, which allow the sleeve 10 to pass through. The absorbent material 20 can then be fitted over the outer periphery of the sleeve 10, with its bottom surface in contact with the ground. The absorbent material 20 has strong water absorption capacity, capable of absorbing slurry leaking from the gap between the sleeve 10 and the ground, preventing slurry from flowing to other areas of the road surface and keeping the road surface clean.

[0037] The absorbent material 20 can be a cuboid, and the width of the absorbent material is greater than the diameter of the sleeve; the height of the absorbent material ranges from 20 to 50 mm. Furthermore, the drain pipe 30 on the sleeve 10 is positioned 20 mm from the bottom of the sleeve.

[0038] Preferably, the absorbent material can be a sponge.

[0039] In some embodiments, the sleeve 10 is frustoconical, meaning the sleeve diameter gradually decreases from the lower opening to the upper opening. The reduced upper diameter helps to further cover the area above the core drill bit, preventing slurry from splashing onto the operator.

[0040] Furthermore, a sealing ring is installed between the through hole 201 of the absorbent material 20 and the outer wall of the sleeve 10. This can be achieved by machining an annular groove on the outer wall of the sleeve 10 and installing the sealing ring in the annular groove, thereby further sealing the gap between the outer periphery of the sleeve and the through hole 201 and preventing slurry from flowing out from there.

[0041] In some embodiments, a weighted strip is provided on the upper edge of the absorbent material 20. For example, the weighted strip can be an iron strip, which can be installed on the upper edge of the absorbent material 20 by means of adhesion, fastener connection, etc. The weighted strip's gravity can press down the edge of the absorbent material 20 to prevent it from lifting up and failing to make close contact with the road surface during core drilling due to vibration or other reasons, thus preventing slurry from flowing out from the lifted area to other areas.

[0042] Furthermore, a sealing gasket is provided on the lower edge of the absorbent material 20. Under the weight of the weighted strip, the sealing gasket is in close contact with the ground, which can better seal the core drilling area surrounded by the absorbent material and prevent the slurry from flowing out.

[0043] In some embodiments, a handle 101 is fixedly connected to the outer wall of the sleeve 10 to allow manual handling of the sleeve 10. The handle 101 may be a rod-shaped extension extending from opposite sides of the outer wall of the sleeve 10. The sleeve can be manually handled by gripping the handle 101 with both hands.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
