Background Technology

[0002] Traditional municipal road manhole cover installation involves placing the manhole cover on the asphalt pavement after the asphalt has been laid, with manual shoveling to replenish the asphalt beneath the manhole seat. Due to uneven shoveling and the asphalt compaction coefficient failing to meet specifications, uneven settlement of the manhole cover can occur after installation due to dynamic loads from vehicles and other factors. This can lead to quality problems and, in severe cases, safety hazards. Furthermore, the installation process is time-consuming and labor-intensive, and subsequent repairs incur additional unnecessary costs.

[0003] Therefore, there is an urgent need for a road construction auxiliary device for manhole cover installation that can improve the efficiency of asphalt paving around the manhole cover, increase the hardness of the asphalt under the manhole cover, and enhance the stability, durability, pressure resistance, and aesthetics of the manhole cover installation. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a road construction auxiliary device for manhole cover installation, in order to solve the problems of uneven material shoveling by manual shoveling in existing construction techniques, and the fact that the asphalt compaction coefficient under the manhole seat does not meet the specifications. After the manhole cover is installed on municipal roads, the presence of dynamic loads from vehicles and other factors above it will cause uneven settlement of the manhole cover, resulting in quality problems and even serious safety hazards. Furthermore, the installation process is time-consuming and labor-intensive, and re-repair will increase new and unnecessary costs.

[0005] This utility model provides a road construction auxiliary device for manhole cover installation, comprising a cylindrical manhole head, a handle disposed on the cylindrical manhole head, and at least two manhole lugs; wherein,

[0006] The cylindrical wellhead includes a top surface and sidewalls;

[0007] The handle is disposed on the upper top surface;

[0008] The well lugs are installed on the side wall, and the distance between the lowest point of each well lug and the top surface is the preset asphalt paving thickness around the well cover.

[0009] Preferably, the number of well ears is three, and the three well ears are fixed at equal intervals on the side wall surface.

[0010] Preferably, the well lug is a metal sheet.

[0011] Preferably, the top of the metal sheet is flush with the top surface.

[0012] Preferably, the metal sheet is welded and fixed to the side wall surface.

[0013] Preferably, two sets of symmetrical fixing holes are provided on the top surface; wherein each set of fixing holes includes two through holes.

[0014] Preferably, it includes two handles; wherein,

[0015] Each handle corresponds to a set of fixing holes.

[0016] Preferably, the handle is a metal strip;

[0017] The main body of the metal strip is placed above the top surface, and both ends of the metal strip extend through the through hole to the inner side of the top surface and are bent to be parallel to the inner sidewall of the top surface.

[0018] Preferably, the top surface and the side wall surface are welded and fixed.

[0019] Preferably, the metal strip is a reinforcing bar.

[0020] As can be seen from the above technical solution, the road construction auxiliary device for manhole cover installation provided by this utility model includes a cylindrical manhole head, a handle, and at least two manhole ears. The cylindrical manhole head includes a top surface and a side wall surface, which are welded and fixed together. The handle is located on the top surface, and the manhole ears are located on the side wall surface. The distance between the lowest point of each manhole ear and the top surface is the pre-set thickness of the asphalt paving around the manhole cover. When the road asphalt is paved to the manhole opening, the entire device is placed at the opening, allowing the side wall surface of the cylindrical manhole head to be inserted into the manhole cylinder. Since the manhole ears are wider than the manhole cylinder, they are supported above the manhole cylinder. Because the size of the manhole head has been determined in advance, asphalt paving can be carried out after the road construction auxiliary device for manhole cover installation of this utility model is placed. After the asphalt paving is completed, the asphalt on the device is cleaned off before road rolling. After the asphalt base layer has cooled, the entire device can be removed using the handle. Since the height of the manhole cover is consistent with the thickness of the asphalt surface layer, after the asphalt paver has finished paving, the device is immediately removed using the handle after being rolled twice by a smooth-drum roller. A five-proof manhole cover is then installed. Because the edge of the five-proof manhole cover is wider than the manhole cylinder, the edge of the five-proof manhole cover will cover the asphalt road around the manhole opening. At this time, the asphalt under the five-proof manhole cover seat is already dense and full, and the height of the manhole cover after installation is the same as the height of the asphalt paving. This ensures that the manhole cover installed by the device of this utility model is level with the road surface, meeting the quality specifications, reducing safety hazards, and lowering subsequent maintenance costs. Furthermore, the device has a simple structure, reasonable design, and low cost, achieving the technical effect that the manhole surface is basically level with the asphalt road surface after the manhole cover is installed.

[0027] Traditional municipal road manhole cover installation involves placing the manhole cover on the asphalt pavement after the asphalt has been laid, with manual shoveling to replenish the material underneath. Due to uneven shoveling and the asphalt compaction coefficient under the manhole cover not meeting the specifications, uneven settlement of the manhole cover can occur after installation due to dynamic loads from vehicles and other factors. This can lead to quality problems and, in severe cases, safety hazards. Furthermore, the installation process is time-consuming and labor-intensive, and subsequent repairs will incur additional unnecessary costs.

[0028] To address the aforementioned problems, this utility model provides a road construction auxiliary device for manhole cover installation. The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] To illustrate the welding machine grounding device provided by this utility model Figures 1-4 The embodiments of this utility model are illustrated by way of example.

[0030] The following description of exemplary embodiments is merely illustrative and is in no way intended to limit the invention or its application or use. Techniques and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques and equipment should be considered part of the specification.

[0031] like Figures 1-4As shown in the figure, this utility model provides a road construction auxiliary device for manhole cover installation, including a cylindrical manhole head 1, a handle 2 and at least two manhole ears 3 disposed on the cylindrical manhole head; wherein, the cylindrical manhole head includes an upper top surface 4 and a side wall surface 5, and the specific fixing method of the upper top surface and the side wall surface is not limited. In this embodiment, the upper top surface 4 and the side wall surface 5 are welded and fixed, but they can also be integrally formed.

[0032] In this embodiment, the handle is set on the top surface. The specific arrangement is not limited. To facilitate control of the asphalt paving thickness, the thickness of the sidewall exposed outside the manhole is designed to be the same as the asphalt paving thickness, which also facilitates compaction by the roller during subsequent compaction. In this embodiment, the handle is positioned so that it rests close to the top surface when not under stress. Therefore, in this embodiment, two sets of symmetrical fixing holes are provided on the top surface to allow two hands to grip the handle, enabling one person to lift the entire device. Each set of fixing holes includes two through holes, corresponding to two handles. Each handle... Corresponding to a set of fixing holes, the handle is a metal strip. To enhance the stability of the handle, the metal strip can be a rigid metal strip to prevent deformation of the handle when lifting the device. The main body of the metal strip is placed above the top surface, and both ends of the metal strip extend through the through holes to the inner side of the top surface (the bottom of the top surface, which is also the inner side of the cylindrical manhole head), and are bent parallel to the inner wall of the top surface. The specific bending direction is not limited; the two ends can be bent relative to each other or in opposite directions, as long as it can withstand the weight of the entire device, thus making it convenient for workers to lift the entire device out of the paved asphalt road using the handle.

[0033] In this embodiment, the well ear is set on the side wall, and the distance between the lowest point of each well ear and the top surface is the preset asphalt paving thickness around the well cover. Thus, when using the device, the entire device is hung on the well cylinder through the well ear, and the height exposed above the well cylinder is the height of the asphalt paving. In this specific embodiment, the diameter of the side wall is smaller than the diameter of the well cylinder so that the side wall can be locked inside the well cylinder when using the device.

[0034] In this embodiment, there are three well ears, and the three well ears are fixed at equal intervals on the side wall to maintain balance when they are hung on the well shaft.

[0035] In one specific embodiment, the manhole ear is a metal sheet, which can be rectangular or square, as long as it can support the entire device to be hung on the manhole. In this specific embodiment, the top of the metal sheet is flush with the top surface, and the metal sheet is welded and fixed to the side wall to improve the stability of the manhole ear. At the same time, the height of the manhole ear can be used as a reference to further ensure the thickness of the asphalt to be laid, so that the compacted asphalt and the manhole cover to be laid are basically level.

[0036] When using the road construction auxiliary device for manhole cover installation in this embodiment, when the asphalt is paved to the manhole opening, the entire device is placed at the manhole opening, so that the side wall of the cylindrical manhole head is inserted into the manhole cylinder. Since the manhole ear is wider than the manhole cylinder, the top of the manhole ear is supported above the manhole cylinder. Since the size of the manhole head has been determined in advance, asphalt paving can be carried out after the road construction auxiliary device for manhole cover installation of this utility model is placed. After the asphalt paving is completed, the asphalt on the device is cleaned. After the road roller compacts and the asphalt base layer cools, the entire device can be taken out by the handle. The height of the manhole ear is the same as the thickness of the asphalt top layer. After the asphalt paver is completed, the device is immediately taken out by the handle after being rolled back and forth twice by a smooth drum roller. The five-proof manhole cover is then replaced with a five-proof manhole cover. Since the edge of the five-proof manhole cover is wider than the manhole cylinder, the edge of the five-proof manhole cover will cover the asphalt road around the manhole opening. At this time, the asphalt under the five-proof manhole cover seat is dense and full, and the height of the manhole cover after placement is the same as the height of the asphalt paving.

[0037] As described above, the road construction auxiliary device for manhole cover installation provided in this embodiment can make the installed manhole cover flush with the road surface, meeting the quality specifications, while reducing safety hazards and subsequent maintenance costs. Moreover, the device has a simple structure, reasonable design, and low cost, achieving the technical effect that the manhole surface is basically flush with the asphalt pavement after the manhole cover is installed.

[0038] The road construction auxiliary device for manhole cover installation according to the present invention has been described above by way of example with reference to the accompanying drawings. However, those skilled in the art should understand that various modifications can be made to the road construction auxiliary device for manhole cover installation according to the present invention without departing from the scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the contents of the appended claims.
