Description

Technical Field

[0001] This utility model relates to the technical field of equipment for asphalt pavement construction, specifically to a protective structure for asphalt concrete highway pavement construction. Background Technology

[0002] Asphalt pavement refers to various types of road surfaces constructed by mixing road asphalt with mineral materials. In asphalt pavement construction, manhole installation is a crucial step. Current manhole construction methods involve pre-installing the manholes, paving the surrounding area with asphalt first, installing manhole covers during paving, and finally leveling the pavement with a road roller. However, during leveling, the road roller can carry some asphalt onto the manhole covers, causing contamination and affecting the overall aesthetics of the road. In severe cases, it can clog gaps in the manhole covers or prevent the manholes from opening, thus hindering their use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a protective structure for asphalt concrete road surface construction, which can effectively prevent asphalt from adhering to the manhole cover during asphalt pavement construction, thereby affecting the appearance of the manhole cover or even blocking the ventilation holes on the manhole cover.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0005] A protective structure for asphalt concrete road surface construction includes a manhole cover mounting frame and a manhole cover body, wherein the manhole cover body is fitted onto the manhole cover mounting frame, and further includes:

[0006] Construction protection structure and quick-installation structure one; the construction protection structure is disassembled and installed on the top surface of the manhole cover body through quick-installation structure one, and completely covers the top surface of the manhole cover body;

[0007] The filter basket and quick-installation structure two; the filter basket can be detachably installed below the manhole cover body through the quick-installation structure two, and all the water flowing through the vent holes on the manhole cover body flows through the filter basket.

[0008] As an improvement, the construction protection structure includes a rubber sheet and a plastic film. The bottom surface of the rubber sheet has grooves that match the pattern on the top surface of the manhole cover. The plastic film is adhered to the top surface by applying silicone sealant, and multiple layers of the plastic film are stacked on top of each other, with adjacent plastic films also adhered together by applying silicone sealant. Tear-off strips are formed on the sides of the plastic film. This provides effective protection for the manhole cover and allows for easy self-cleaning after use.

[0009] As an improvement, the quick-installation structure includes a handle screw and a knob nut; the construction protection structure has through holes pre-drilled for each vent hole on the manhole cover body, and the threaded rod of the handle screw passes through the interconnected vent holes and through holes. The knob nut is then threaded onto the handle screw, and after tightening the knob nut, the construction protection structure is fixed to the manhole cover body. This allows for convenient installation and removal of the construction protection structure.

[0010] As an improvement, the filter basket is a round basket with the opening facing upwards. The second quick-installation structure includes a lifting rod, a threaded sleeve, and a threaded post. Multiple lifting rods are fixed to the top of the filter basket, evenly spaced circumferentially. After a threaded section is formed at the top of the lifting rod, a threaded post fixed to the bottom surface of the manhole cover body is attached to the top surface. The threaded sleeve is threaded onto both the threaded section of the lifting rod and the threaded post. The filter basket can be easily installed and removed, facilitating regular cleaning of the filtered debris.

[0011] The advantages of this utility model compared with the prior art are as follows:

[0012] 1. When using this new type of construction protection structure, it can effectively prevent asphalt from adhering to the manhole cover body during asphalt pavement construction. The construction protection structure can be easily installed and removed. After the asphalt pavement construction is completed, the cleaning work of the construction protection structure can be completed by tearing off the top layer of plastic film.

[0013] 2. When in use, the filter basket can filter the water flowing in through the vent, thereby effectively preventing particulate matter and other debris in the water from flowing into the sewer and causing easy blockage of the sewer. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] A protective structure for asphalt concrete road surface construction includes:

[0023] The manhole cover mounting frame 2 and the manhole cover body 1 are fitted onto the manhole cover mounting frame 2;

[0024] The construction protection structure and quick-installation structure one are as follows: The construction protection structure includes a rubber sheet 4 and a plastic film 5; the bottom surface of the rubber sheet 4 has a groove that matches the pattern on the top surface of the manhole cover body 1; the top surface is coated with silicone and bonded with a plastic film 5; multiple plastic films 5 are stacked vertically, and adjacent plastic films 5 are also bonded with silicone; a tear strip 6 is formed on the side of the plastic film 5. The quick-installation structure one includes a handle screw 7 and a knob nut 8; the construction protection structure has through holes corresponding to the vents on the manhole cover body 1; after the threaded rod of the handle screw 7 passes through the interconnected vents and through holes, the knob nut 8 is threaded onto the handle screw 7; after tightening the knob nut 8, the construction protection structure is fixed to the manhole cover body 1.

[0025] The filter basket 3 and the quick-installation structure 2 are described. The filter basket 3 is a round basket with the opening facing upwards. The quick-installation structure 2 includes a lifting rod 9, a threaded sleeve 10, and a threaded post 11. The top of the filter basket 3 is fixed with multiple lifting rods 9 evenly arranged circumferentially. After the top of the lifting rod 9 is formed with a threaded section, a threaded post 11 fixed to the bottom surface of the manhole cover body 1 is attached to the top surface. The threaded sleeve 10 is threadedly sleeved on both the threaded section of the lifting rod 9 and the threaded post 11.

[0026] In the specific implementation of this embodiment:

[0027] likeFigure 1 and 2 As shown, the construction protection structure is first installed and fixed on the top surface of the manhole cover body 1, and then the asphalt pavement construction is carried out. After the construction is completed, the construction protection structure is removed. In this way, asphalt will not adhere to the top surface of the manhole cover body 1. After tearing off the plastic film 5 on the top layer of the construction protection structure, the cleaning work of the construction protection structure can be completed (most of the asphalt will adhere to the top surface of the construction protection structure, so the cleaning work can be completed after removing the asphalt on the top surface).

[0028] In situations such as rain, water on the road surface will inevitably flow into the sewers through the vents (e.g., Figure 5 As described above, interconnected guide pipes can be installed on the bottom surface of the manhole cover body 1 corresponding to each vent hole, so that the water flowing through the vent holes will basically flow through the filter basket 3. At this time, the filter basket 3 can effectively filter the flowing water. The filter basket 3 needs to be disassembled regularly and the debris inside should be cleaned, or it should be replaced directly.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
