[0004] The utility model is realized by the following technical solutions: A modular light - type invisible inspection well cover includes a side cover plate and a middle cover plate. The side cover plate is located on one side of the middle cover plate. A inspection well is arranged at the bottom of the side cover plate and the middle cover plate. A first matte stainless - steel embedded part is arranged at the bottom of the side cover plate, and a second matte stainless - steel embedded part is arranged at the bottom of the middle cover plate. The two first matte stainless - steel embedded parts are located on both sides of the second matte stainless - steel embedded part. The first matte stainless - steel embedded part and the second matte stainless - steel embedded part are located above the inspection well.
[0005] Preferably, a 2 - mm - thick and 5 - cm - high U - shaped matte stainless - steel plate is arranged on one side of the first matte stainless - steel embedded part, and a 5 - mm - thick and 5 - cm - high U - shaped matte stainless - steel plate is arranged on the other side of the first matte stainless - steel embedded part.
[0006] Preferably, two 2 - mm - thick and 5 - cm - high U - shaped matte stainless - steel plates are arranged on both sides of the second matte stainless - steel embedded part. The 2 - mm - thick and 5 - cm - high U - shaped matte stainless - steel plate on one side of the first matte stainless - steel embedded part is close to the 2 - mm - thick and 5 - cm - high U - shaped matte stainless - steel plate on the side close to the second matte stainless - steel embedded part.
[0007] Preferably, the side cover plate and the middle cover plate are composed of a 20 - mm - thick 1:3 cement mortar bonding layer and 10 - mm epoxy colored sand.
[0008] Preferably, the inside of the side cover plate and the middle cover plate is formed by laying 8 steel bars in a single - layer and two - way manner and then pouring mortar.
[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0010] In the utility model, starting from the perspective that the inspection well can be independently opened by manual labor, the size and weight of the inspection well are determined, which is convenient for pipeline operation and maintenance, and the invisible manhole cover is more popularizable.
[0011] In the present utility model, the inspection well covers have unified specifications, realizing modularization, facilitating fabrication and installation, with a simple structure, being easy to fabricate, and having a relatively low investment.
[0012] In the present utility model, the boundary of the inspection well cover is made invisible to the greatest extent, and the inspection well cover is integrated with the sidewalk paving. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Next, in combination with the drawings and the specific embodiments, the present utility model will be further described. It should be noted that on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.
[0019] Embodiment 1: Please refer to Figure 1 - Figure 4 , a modular lightweight invisible inspection well cover in this embodiment includes a side cover plate 1 and a middle cover plate 2. The side cover plate 1 is located on one side of the middle cover plate 2. An inspection well 5 is provided at the bottom of the side cover plate 1 and the middle cover plate 2. A first matte stainless steel embedded part 3 is provided at the bottom of the side cover plate 1, and a second matte stainless steel embedded part 4 is provided at the bottom of the middle cover plate 2. The two first matte stainless steel embedded parts 3 are located on both sides of the second matte stainless steel embedded part 4, and the first matte stainless steel embedded part 3 and the second matte stainless steel embedded part 4 are located above the inspection well 5;
[0020] This product is a composite well cover combining stainless steel, reinforced concrete and sidewalk slabs with lightweight and low visibility. Based on the weight of the manually openable well cover, the invisible well cover is divided into several standard cover plates to reduce the weight of a single cover plate. A further invisible design is adopted at the joint of the middle cover plate 2 to minimize the gap between the side cover plate 1 and the middle cover plate 2, achieving a perfect combination of the inspection well 5 and the sidewalk paving;
[0021] By fabricating a stainless-steel inspection well frame and then installing the inspection well cover according to the sidewalk paving style;
[0022] Further, on one side of the first matte stainless-steel embedded part 3, there is a 2-mm-thick and 5-cm-high U-shaped matte stainless-steel plate, and on the other side of the first matte stainless-steel embedded part 3, there is a 5-mm-thick and 5-cm-high U-shaped matte stainless-steel plate. On both sides of the second matte stainless-steel embedded part 4, there are two 2-mm-thick and 5-cm-high U-shaped matte stainless-steel plates. The 2-mm-thick and 5-cm-high U-shaped matte stainless-steel plate on one side of the first matte stainless-steel embedded part 3 is close to the 2-mm-thick and 5-cm-high U-shaped matte stainless-steel plate on one side of the second matte stainless-steel embedded part 4;
[0023] Among them, to maximize the invisibility of the inspection well cover boundary and integrate the inspection well cover with the sidewalk paving, starting from the perspective that the inspection well 5 can be independently opened manually, the size and weight of the inspection well 5 are determined to facilitate pipeline operation and maintenance. The invisible cover is more popularizable;
[0024] Secondly, the width of the side cover plate 1 and the middle cover plate 2 is set to 45 cm, and the length is set to 90 cm;
[0025] Further, the side cover plate 1 and the middle cover plate 2 are composed of a 20-mm-thick 1:3 cement mortar bonding layer and 10-mm epoxy colored sand. Inside the side cover plate 1 and the middle cover plate 2, they are composed of 8 steel bars laid in a single layer and two-way and then mortar-cast. The inspection well cover is modularized with unified specifications, which is convenient for fabrication and installation, has low cost, simple structure, is easy to fabricate, and has low investment. This cover can be applied to various municipal pipeline inspection wells at the sidewalk.
[0026] Working principle: Based on the weight of the manually openable well cover, the invisible well cover is divided into several standard cover plates to reduce the weight of a single cover plate. At the joint of the middle cover plate 2, a further invisible design is adopted to minimize the gap between the side cover plate 1 and the middle cover plate 2, achieving a perfect combination of the inspection well 5 and the sidewalk paving. By fabricating a stainless-steel inspection well frame and then installing the inspection well cover according to the sidewalk paving.
[0027] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention fall within the protection scope required by the present invention.
