Description
Technical Field
[0001] This application relates to the field of road construction technology, specifically to a road surface core sampling and pollution prevention device and system. Background Technology
[0002] Currently, in road construction, core drilling is commonly used to obtain core samples in order to test the thickness and compaction of the road surface. Core sampling is an important method for judging the quality of road construction.
[0003] In related technologies, wastewater from the core drilling machine is prone to splashing during the core sampling and testing process, which pollutes the road surface. Moreover, the wastewater is difficult to treat, cannot be cleaned up, and washing is labor-intensive and time-consuming. The wastewater from washing can also cause secondary pollution.
[0004] Therefore, it is necessary to design a new road surface core sampling and pollution prevention device to overcome the above problems. Utility Model Content
[0005] This application provides a road surface coring pollution prevention device and system, which can solve the technical problems in the related technology that the coring process is prone to the splashing of sewage from the core drilling machine, which pollutes the road surface. Moreover, the sewage is difficult to treat, cannot be cleaned, and the washing is labor-intensive and time-consuming, and the sewage from the washing will cause secondary pollution.
[0006] In a first aspect, embodiments of this application provide a road surface core sampling and pollution prevention device, which includes: a sleeve, a drain pipe connected to one side of the sleeve, a water stop valve provided in the drain pipe, a base provided at the bottom of the sleeve, a through hole provided in the base, the through hole being connected to and coaxially arranged with the inside of the sleeve, and the base being used for placement on the road surface.
[0007] The sleeve is used to collect wastewater generated during core drilling, preventing wastewater from splashing and contaminating the road surface. The drain pipe is used to guide the wastewater to a set location. The stop valve is used to control the flow of wastewater through the drain pipe. The bottom of the sleeve is equipped with a base, which has a through hole that is coaxially connected to the sleeve, allowing the road surface core sampling anti-pollution device to accommodate the core drilling machine and cooperate with its operation. The base serves as a counterweight and seal, preventing wastewater leakage from the sleeve and contamination of the road surface. The sleeve can be a hollow cylinder. The road surface core sampling anti-pollution device is lightweight, practical, labor-saving, and efficient. It can collect wastewater generated during core sampling of asphalt or cement pavement, preventing it from contaminating the pavement, and also saves the labor cost of cleaning contaminated pavement, thus helping to ensure the quality of road construction. The road surface core sampling anti-pollution device is applicable to various road surfaces and can be reused.
[0008] In conjunction with the first aspect, in one embodiment, the inner diameter of the sleeve is set to 130-160 mm.
[0009] The inner diameter of the sleeve can be set to 130-160 mm, preferably 150 mm, so that the inner cavity of the sleeve has enough space to accommodate the core drilling machine and allow the drill bit of the core drilling machine to pass through the sleeve. The inner diameter of the sleeve is set according to the standard size of road core sampling Φ100 mm. If the standard size of road core sampling is greater than Φ150 mm, the inner diameter of the sleeve needs to be increased accordingly.
[0010] In conjunction with the first aspect, in one embodiment, the height of the sleeve is set to 180–220 mm.
[0011] The height of the sleeve can be set to 180-220 mm. Preferably, the height of the sleeve is set to 200 mm, so that the sleeve is 200 mm higher than the ground surface and less than the effective working length of the core drill bit, while facilitating the operation of the core drill outside the sleeve.
[0012] In conjunction with the first aspect, in one embodiment, the outer diameter of the base is set to 150-200 mm.
[0013] The outer diameter of the base is larger than the inner diameter of the sleeve. The outer diameter of the base can be set to 150-200 mm, preferably 190 mm, to prevent the sleeve from tipping over during the auxiliary core drilling process.
[0014] In conjunction with the first aspect, in one embodiment, the base is provided with a sealing ring at its bottom, and the base contacts the road surface through the sealing ring.
[0015] The base includes a sealing ring at its bottom, which is pressed together by the weight of the sleeve to prevent wastewater generated during core drilling from leaking and contaminating the road surface. In other embodiments, the bottom of the base may be sealed with a material such as modeling clay or silicone sealant.
[0016] In conjunction with the first aspect, in one embodiment, the sleeve is provided with handles on both sides, and the length of the handles is set to 50-70 mm.
[0017] The sleeve has handles on opposite sides to facilitate the placement and removal of the road coring and pollution prevention device. The handles can be 50-70 mm long, preferably 60 mm. In other embodiments, a collar can be provided on the outer side of the sleeve to facilitate the placement and removal of the road coring and pollution prevention device.
[0018] In conjunction with the first aspect, in one embodiment, a water collection container is provided below the end of the drain pipe.
[0019] The water collection container is used to transfer the wastewater generated during the core drilling process to prevent the wastewater from polluting the road surface. The water collection container can be set as a basin, bucket or tank to facilitate wastewater transfer and save costs.
[0020] In conjunction with the first aspect, in one embodiment, the drain pipe is configured as a flexible hose.
[0021] The drain pipe is a transparent flexible tube to facilitate adjustment of the flow direction of wastewater generated during core drilling, and to allow observation of the wastewater's condition within the drain pipe. In other embodiments, the drain pipe may be a steel pipe.
[0022] In conjunction with the first aspect, in one embodiment, the sleeve is made of steel.
[0023] The sleeve is made of Q235 steel to ensure its supporting strength while reducing its material cost.
[0024] Secondly, this application provides a road surface core sampling and pollution prevention system, which includes: a sleeve and a core drill. A drain pipe is connected to one side of the sleeve, and the drain pipe is equipped with a water stop valve. A base is provided at the bottom of the sleeve, and the base is provided with a through hole. The through hole is connected to the sleeve and coaxially arranged. The base is placed on the road surface. The core drill is inserted into the sleeve.
[0025] The process involves selecting a core sampling location on the road surface and cleaning the surface. A sleeve is placed at the core sampling location, and a core drill is inserted into the sleeve. The drill bit of the core drill penetrates the sleeve and is positioned at the center of the sleeve to prevent it from scraping or moving during rotation. The core drill is started, and wastewater generated during the drilling process is collected inside the sleeve. The stop valve is opened to transfer the wastewater to a collection container. After drilling is completed, the core drill is removed, the wastewater inside the sleeve is drained, and the drilled core sample is retrieved, completing the core sampling operation. The road surface core sampling pollution prevention system collects wastewater generated during the core drilling process in a directional manner, preventing wastewater from splashing onto operators or being randomly discharged onto the road surface, causing environmental pollution and safety hazards.
[0026] The beneficial effects of the technical solutions provided in this application include:
[0027] By installing a drain pipe on one side of the sleeve and a stop valve on the drain pipe, the wastewater generated during the core sampling process can be blocked within the sleeve and discharged through the drain pipe, preventing wastewater from splashing and polluting the road surface. By installing a base at the bottom of the sleeve and placing the base on the road surface, the wastewater is sealed inside the sleeve, preventing wastewater from leaking inside the sleeve and polluting the road surface. This solves the technical problems in related technologies where wastewater from the core drilling machine easily splashes and pollutes the road surface during the core sampling and testing process, and where wastewater treatment is difficult, cannot be cleaned thoroughly, and washing is labor-intensive and time-consuming, and the washing wastewater causes secondary pollution.
