[0016] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0017] A municipal pipe trench cornice repair structure, such as Figure 1 and Figure 2 As shown, it includes a trench base 1, a trench foundation 2, a municipal trench main body 3 and a damaged eaves residual part 3.1; a trench foundation 2 is fixed on the trench base 1, and a left and right municipal trench main body 3 are fixed on the trench foundation 2, and at least one of the municipal trench main bodies 3 has an eaves damaged residual part 3.1 at the upper end; it also includes an eaves channel steel 4, a fastening bolt 5 and an eaves pouring part 6; the eaves channel steel 4 includes a channel steel top plate 4.1 and a channel steel side plate 4.2 fixed to the left and right ends of the lower surface of the channel steel top plate 4.1, a grouting port 4.11, a grouting port 4.12 and an air outlet 4.13 are opened on the channel steel top plate 4.1, and the upper end of the fastening bolt 5 is fixed to the channel steel top plate 4.1;

[0018] An eaves pouring part 6 is provided above the eaves damaged residual part 3.1, and the eaves pouring part 6 entirely fills the cavity formed by the eaves damaged residual part 3.1 and the eaves channel steel 4, and the lower end of the fastening bolt 5 is fastened in the eaves damaged residual part 3.1.

[0019] The channel steel side plates 4.2 are arranged vertically to the channel steel top plate 4.1.

[0020] The eaves channel steel 4 is as wide as the damaged residual portion 3.1 of the eaves, and the outer side surface of the channel steel side plate 4.2 is flush with the side wall of the corresponding damaged residual portion 3.1 of the eaves.

[0021] The fastening bolts 5 are fully welded to the channel steel top plate 4.1 of the eaves channel steel 4.

[0022] The grouting port 4.11 is arranged at one end of the channel steel top plate 4.1, the grouting port 4.12 is arranged at the other end of the channel steel top plate 4.1, and the air outlet 4.13 is arranged at the middle position of the channel steel top plate 4.1.

[0023] The production steps of the municipal pipe trench cornice repair structure of the utility model are as follows:

[0024] First, make an eaves channel steel 4 of the same width as the damaged residual part 3.1 of the eaves (i.e., the main body 3 of the municipal trench). Before installing the eaves channel steel 4, check the elevation of the laying position of the eaves channel steel 4. Clean the damaged part of the eaves, use high-strength fastening bolts 5 and use the chemical anchoring method to implant the fastening bolts 5. After the reserved interface on the channel steel top plate 4.1 of the eaves channel steel 4 is aligned with the fastening bolts 5, use a rubber hammer to fine-tune the eaves channel steel 4 so that the eaves channel steel 4 is installed horizontally and vertically, and the elevation of the eaves channel steel 4 is consistent with the elevation of the road surface. Cut the excess fastening bolts 5 and use electric welding to tightly connect the eaves channel steel 4 and the fastening bolts 5.

[0025] The prepared grouting material is poured into the cavity formed by the damaged residual part of the eaves 3.1 and the eaves channel steel 4 through the grouting port 4.11. The air outlet 4.13 can discharge the air in the cavity formed by the damaged residual part of the eaves 3.1 and the eaves channel steel 4 during the grouting process, which is conducive to the flow of slurry. The eaves channel steel 4 is knocked to self-vibrate and compact the grouting material. When slurry flows out from the slurry outlet 4.12, the surface slurry has filled the cavity formed by the damaged residual part of the eaves 3.1 and the eaves channel steel 4. The grouting process is completed. After the slurry is cooled, the eaves pouring part 6 is formed. After the grouting is completed, normal curing is carried out, and the curing can be completed after 2 hours.

[0026] The eaves channel steel 4, the fastening bolts 5 and the eaves pouring part 6 in the utility model are an integrated structure, and the structure is tight and has high strength. The utility model uses high-strength grouting materials to form the eaves channel steel 4, the fastening bolts 5 and the eaves pouring part 6 as one piece, thereby increasing the overall strength of the components of the eaves channel steel 4, the fastening bolts 5 and the eaves pouring part 6, and is not easy to be damaged.

[0027] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
