DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Please see attached Figure 1 To Attachment Figure 4 and attached Figure 6 A road manhole cover leveling installation auxiliary device comprises a leveling support top assembly 1, a transparent adjustment disk 2 and an adjustment assembly 3; a plurality of groups of leveling support top assemblies 1 are respectively embedded in a concrete pipe base 4 for installing a manhole cover 6, and the transparent adjustment disk 2 is placed on the top of the plurality of groups of leveling support top assemblies 1, and the size of the transparent adjustment disk 2 is consistent with the size of the manhole cover 6 to be installed; the adjustment assembly 3 is arranged in the middle of the transparent adjustment disk 2, and the adjustment assembly 3 is arranged facing the curb 5 outside the manhole cover 6, so that the top surface of the plurality of groups of leveling support top assemblies 1 is flush with the installation surface of the bottom surface of the manhole cover 6, so that the manhole cover 6 is arranged on the plurality of groups of leveling support top assemblies 1 and cast and embedded in the road surface.

[0025] Preferably, the transparent adjustment disk 2 can be made of lightweight materials such as plastic and customized according to the size of the manhole cover 6 to be installed. The transparent adjustment disk 2 is placed on several groups of leveling support assemblies 1, and the transparent adjustment disk 2 is accurately adjusted to the installation position through the leveling support assemblies 1 combined with the adjustment assembly 3. Since the transparent adjustment disk 2 is light in weight, it is used to replace the direct adjustment of the heavy manhole cover 6, making the adjustment process easier and more convenient. After the transparent adjustment disk 2 is adjusted to the designated installation position of the manhole cover 6, the transparent adjustment disk 2 is removed, and the manhole cover 6 is directly installed on several groups of leveling support assemblies 1. The position of the manhole cover 6 is the designated installation position, and the installation of the manhole cover 6 is completed.

[0026] Please see attached Figure 5 Each set of the leveling support assembly 1 includes a fixing screw 101, a fixing screw 102 and a nut barrel 103; the fixing screw 101 is embedded in the concrete pipe base 4, one end of the fixing screw 102 is matched and screwed into the fixing screw 101, and the other end of the fixing screw 102 extends upward to the top of the concrete pipe base 4; the nut barrel 103 is adjustably screwed on the fixing screw 102; the transparent adjustment disk 2 or the manhole cover 6 can be placed on the top of the nut barrel 103 of several sets of leveling support assemblies 1.

[0027] Since several groups of leveling support assemblies 1 need to bear the weight of the heavy manhole cover 6, the fixing screw 101 may preferably be a chemical expansion screw, which can be used to provide stable support to ensure the stability of the manhole cover 6. At the same time, the installation stability and force uniformity of the manhole cover 6 can be further improved by four groups of leveling support assemblies 1 arranged at equal intervals, so as to keep the manhole cover 6 stable and not tilted during the pouring of road concrete.

[0028] The fixing screw 102 is fixedly installed on the fixing screw 101 by means of threads, and the nut barrel 103 is screwed onto the fixing screw 102. By rotating the nut barrel 103 by means of threads, the height of the nut barrel 103 relative to the fixing screw 101 and the concrete pipe base 4 can be adjusted, thereby adjusting the height of the transparent adjustment disk 2 at different supporting points through several groups of nut barrels 103 of the leveling support top assembly 1, that is, adjusting the horizontality of the transparent adjustment disk 2, thereby ensuring that the horizontality of the manhole cover 6 installed subsequently is of high accuracy.

[0029] Please see attached Figure 2 A plurality of hollow portions 201 are formed between the middle and the edge of the transparent adjustment disk 2 , which can reduce the weight of the transparent adjustment disk 2 .

[0030] Preferably, four hollow portions 201 can be centrally symmetrically arranged to ensure uniform mass distribution of the transparent adjustment disk 2 and high precision of level adjustment.

[0031] Please see attached Figure 2The adjustment component 3 includes a central adjustment disk (not shown in the figure) coaxially installed in the middle of the transparent adjustment disk 2, and a digital slope ruler 301 and a laser emitter 302 installed on the central adjustment disk; at least two laser emitters 302 are arranged at intervals on the transparent adjustment disk 2 and facing the curb 5, so that the laser line of the laser emitter 302 is irradiated on the side walls of the curb 5 on both sides of the manhole cover 6; a pair of digital slope rulers 301 are arranged perpendicular to each other in the middle of the transparent adjustment disk 2.

[0032] Preferably, the laser emitter 302 is a laser pen, which is symmetrically arranged on both sides of the central adjustment disk, so as to emit a laser beam to the curbstones 5 on both sides of the manhole cover 6. Since the transparent adjustment disk 2 is made of transparent plastic material, it is ensured that the laser beam of the laser emitter 302 can penetrate the transparent adjustment disk 2 and irradiate the curbstones 5.

[0033] The digital slope ruler 301 can display the slopes in the X and Y directions in the horizontal plane in real time during the level adjustment process, so as to accurately adjust the level of the transparent adjustment disk 2 and further determine the level of the manhole cover 6.

[0034] Please see attached Figure 2 The adjustment component 3 also includes a horizontal bubble 303, which is embedded in the center of the top surface of the transparent adjustment disk 2.

[0035] When the bubble of the level bubble 303 is centered, it can be determined that the top surface of the transparent adjustment disk 2 is in the horizontal plane, thereby ensuring the installation level of the transparent adjustment disk 2. By setting the level bubble 303, the levelness of the auxiliary manhole cover 6 can be further accurately and efficiently adjusted.

[0036] Please see attached Figure 1 and attached Figure 2 The laser beam of the laser emitter 302 has a fan-shaped surface structure and forms a straight laser beam on the curb 5, and the laser beam coincides with the elevation line of the top surface of the manhole cover 6.

[0037] After the construction of the curb 5 is completed, before the road construction, the construction personnel will lay out the line on the curb 5 according to the elevation of the finished road surface, so as to facilitate the determination of the finished surface during the road construction. At the same time, the top surface of the manhole cover 6 should be flush with the finished road surface to avoid the manhole cover 6 from protruding or sinking, so that the laying out line can also be used as a standard line when installing the manhole cover 6. Therefore, by coinciding the laser beam with the laying out line, i.e., the elevation line of the top surface of the manhole cover 6, it can be ensured that the manhole cover 6 is flush with the finished road surface after installation.

[0038] The fan-shaped laser surface of the laser emitter 302 is parallel to the bottom surface of the transparent adjustment disk 2, and the distance between the fan-shaped laser surface and the bottom surface of the transparent adjustment disk 2 is consistent with the thickness of the manhole cover 6 to be installed.

[0039] Preferably, the central adjustment disk can be installed on the transparent adjustment disk 2 by rotating a screw, and the laser emitter 302 is installed on both sides of the central adjustment disk. The height of the laser emitter 302 is controlled by lifting and lowering the central adjustment disk relative to the transparent adjustment disk 2 to adapt to manhole covers 6 of different thicknesses.

[0040] The laser emitter 302 emits a fan-shaped laser and irradiates the inner wall of the curb 5 to form a laser beam. When the laser beam coincides with the lofting line of the finished road surface, the bottom surface of the transparent adjustment plate 2, the top surfaces of the plurality of nut cylinders 103 and the bottom installation surface of the manhole cover 6 are at the same height. At this time, the transparent adjustment plate 2 is removed, and the manhole cover 6 is placed on the top surfaces of the plurality of nut cylinders 103. The position of the manhole cover 6 is consistent with the installation design elevation, and the horizontality of the manhole cover 6 can meet the design requirements, and the top surface of the manhole cover 6 is flush with the road surface.

[0041] Please see attached Figure 1 To Attachment Figure 6 The method of using the utility model when installing the manhole cover 6 is:

[0042] The concrete pipe base 4 and the curbstone 5 are constructed using conventional techniques, which will not be described in detail here. Lines are set out at the road surface elevation on the curbstones 5 on both sides of the manhole cover 6 for reference in subsequent adjustments. The road surface elevation is also the top elevation of the manhole cover 6 after installation, ensuring that the surface of the manhole cover 6 is flush with the road surface.

[0043] Drill a hole on the concrete pipe base 4 embedded in the manhole cover 6, use an air compressor to blow and clean the hole, put in a chemical expansion agent after cleaning the hole, and use a hammer to vertically hammer the fine pitch fixing screw 101 into the hole to ensure that the bottom is dense and can provide sufficient support. After the chemical expansion agent hardens to fix the fixing screw 101, screw in the fixing screw 102 to the bottom of the fixing screw 101, and then screw the nut barrel 103 onto the fixing screw 102, and screw the nut barrel 103 halfway in to retain the upper and lower adjustment distance.

[0044] The top elevation of the fixing screw 102 is determined according to the actual working conditions and should not be too short or too long to avoid exceeding the adjustment range of the nut barrel 103. According to the diameter of the concrete pipe base 4, four sets of leveling support assemblies 1 can be set at equal intervals, and the number of leveling support assemblies 1 can also be increased or decreased according to actual use requirements. The installation method of each set of leveling support assemblies 1 is the same, and will not be repeated here.

[0045] According to the diameter of the manhole cover 6 to be installed, a transparent adjustment disk 2 of the same diameter is selected. According to the thickness of the manhole cover 6 to be installed, a pair of laser emitters 302 are symmetrically arranged in the middle of the transparent adjustment disk 2 through the central adjustment disk, so that the fan-shaped laser surfaces of the pair of laser emitters 302 are parallel to the bottom surface of the transparent adjustment disk 2, and the distance between the fan-shaped laser surface and the bottom surface of the transparent adjustment disk 2 is consistent with the thickness of the manhole cover 6.

[0046] Place the transparent adjustment disk 2 on the top of the nut barrel 103 of the four-group leveling support assembly 1, and preliminarily rotate the adjustment nut barrel 103 so that the fan-shaped laser surface of a pair of laser emitters 302 can illuminate the inner walls on both sides of the curb 5, completing the preliminary adjustment of the position of the manhole cover 6.

[0047] The transparent adjustment disk 2 is precisely adjusted in combination with the level bubble 303, the nut cylinder 103 and the digital slope scale 301, so that the laser beam formed by the fan-shaped laser surface of a pair of laser emitters 302 irradiating the curbstones 5 on both sides coincides with the layout line at the elevation of the finished road surface on the curbstones 5 on both sides, that is, the laser beam is flush with the top surface of the manhole cover 6 to be installed.

[0048] Remove the transparent adjustment plate 2, and place the manhole cover 6 to be installed on the top of the nut barrel 103 of the four sets of leveling support assemblies 1, so that the top elevation of the manhole cover 6 is consistent with the elevation of the finished road surface. Concrete the road, so that the outer ring mounting frame of the manhole cover 6 is fixedly installed on the road, and the leveling support assembly 1 is poured inside the road, which can support the manhole cover 6 without affecting the concrete strength of the road and the installation firmness of the manhole cover 6.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
