Embodiment 1
[0032] Example 1, such as figure 1 As shown, this embodiment provides an urban comprehensive prefabricated pipe corridor open-cut self-protection construction method. Specifically, this embodiment describes in detail that the width of the prefabricated pipe fittings is 2.7m and the laying depth is 8m.
[0033] First of all, here is a detailed description of the traditional process. In the traditional construction for this type of work, the width of the ground that needs to be excavated is about 13m, and the width of the lowest part is about 3.5m. Then, use the gantry crane to place the prefabricated pipe fittings into the excavated open ditch, and then the workers adjust the corresponding position to ensure that there is no deviation, then fix them, and then backfill, due to the backfill process on both sides of the prefabricated pipe fittings , cannot be compacted with a road roller, so a little bit of manual compaction is required. Due to the limited degree of manual compact...
Embodiment 2
[0041] Embodiment 2, this embodiment provides a self-propelled laying machine, and its utility model patent was applied for on the same day under the name of self-protection self-propelled laying machine for urban comprehensive pipe gallery.
[0042] Such as figure 2 , image 3 , Figure 4 As shown, the present embodiment provides a self-propelled paver, including a shoveling part 1 and a laying part 2 connected to each other. Part 2 is mainly used for laying prefabricated pipe fittings to achieve the purpose of urban comprehensive pipe gallery construction. It should be noted here that the structure provided in this embodiment is limited to the laying of urban comprehensive pipe gallery with an excavation depth below 8m.
[0043] In order to achieve the above purpose, in this embodiment, the provided shoveling section 1 includes a frame-shaped shoveling section body 11 and shoveling boards 12 arranged on both sides of the shoveling section body 11. The whole body 11 of th...
