[0031] The grate repair tool includes a grate edge protection mold, a mold inner lining protection plate, and an adjustable support rod. The inner diameter of the grate edge protection mold matches the outer contour of the rainwater inlet grate assembly. The outer side of the mold inner lining protection plate fits and supports against the well wall of the rainwater well, and the inner side of the mold inner lining protection plate fits and supports against the end of the adjustable support rod.

[0032] Specifically, the tool kit includes a manhole cover repair tool and a grate repair tool, which can meet the repair requirements of underground pipe network manhole facilities at the same time. When repairing the manhole cover, after the construction of the circle cutting machine is completed, select a manhole cover edge protection mold of the corresponding size to cover the ground. The part exposed in the middle of the manhole cover edge protection mold needs to place the manhole cover assembly and black mixed cement. Before placing the manhole cover assembly, place the manhole cover anti-side leakage mold below to support the manhole cover assembly and prevent the black mixed cement from falling into the sewer. Finally, after the installation of the manhole cover assembly is completed, cover the anti-pollution mold on the manhole cover to avoid polluting the manhole cover during the cement plastering; when repairing the rainwater inlet grate, use the grate edge protection mold to limit the construction area of the black mixed cement, and then use the mold inner lining protection plate and the adjustable support rod to support and limit the well wall profile. When the strength of the black mixed cement meets the requirements, the mold inner lining protection plate and the adjustable support rod can be removed.

[0041] Specifically, before pouring the black mixed cement on the outer peripheral surface of the manhole cover, the waterproof cloth is covered on the manhole cover and fixed to the manhole cover by magnetic attraction to prevent the waterproof cloth from being blown away. In this way, the black mixed cement will not be poured onto the manhole cover, causing adhesion between the manhole cover and the manhole ring or blockage of the manhole cover holes.

[0042] Optionally, the grate edge protection mold includes multiple long strips, the long strips are made of stainless steel, and a second handle is arranged on one side of the long strips.

[0043] Specifically, the use method of the grate edge protection mold is the same as that of the manhole cover edge protection mold, except that a rectangular area is formed inside after the grate edge protection mold is surrounded, and this rectangular area is used to place the rainwater inlet grate assembly; the poured black mixed cement is supported and limited by the inner side of the long strips to ensure that the shape of the black mixed cement does not change before the strength reaches the process requirements; the second handle is beneficial for adjusting the position of the long strips so that the grate edge protection mold can be applicable to rainwater inlet grate assemblies of multiple sizes.

[0044] Optionally, the mold inner lining protection plate includes four inner lining plates, and a flanging is arranged at one end of the inner side of the inner lining plates, and the flanging fits with the edge of the rainwater grate base.

[0045] Specifically, the four inner lining plates are selected and installed according to the internal size requirements of the rainwater inlet, and then the gap between the inner lining plates in the opposite direction is adjusted by the adjustable support rods to ensure the support strength of the inner lining plates, so that the black mixed cement will not flow randomly after pouring.

[0046] Optionally, the adjustable support rods include a first group of support rods and a second group of support rods. The first group of support rods is arranged along the length direction of the rainwater inlet grate assembly, and the second group of support rods is arranged along the width direction of the rainwater inlet grate assembly. The first group of support rods and the second group of support rods each include two support rods.

[0047] Optionally, the support rod includes a metal pipe and a bolt. One end of the metal pipe is provided with a nut, the bolt is screwed with the nut, and the threaded portion of the bolt is inserted into the metal pipe.

[0048] Specifically, after placing the four inner lining plates inside the rainwater inlet, then place the support rods in sequence. Then, according to the required inner size of the rainwater inlet, adjust the length of the bolt extending out to make the inner lining plates supported in place. Then, pour black mixed cement on the outer side of the inner lining plates, place the rainwater grate base on the inner side of the inner lining plates, and support the rainwater grate base through the flanging to ensure the correct position of the rainwater grate in the vertical direction. After the strength of the black mixed cement reaches the process requirements, remove the support rods and inner lining plates in sequence.
