As shown in fig. 1, the communication cable 9 and the electric power cable 10 are provided at intermediate positions inside the micro-pipe rack 1, and the electric power brackets (upright posts) 11 and the electric power brackets (cross arms) 12 are provided at both sides inside the micro-pipe rack 1, respectively, and the communication cable 9 and the electric power cable 10 are provided at the electric power brackets (cross arms) 12 at both sides inside the micro-pipe rack 1, respectively. The communication cable 9 and the power cable 10 are arranged bilaterally inside the micro tube rack 1, facilitating the branching of the micro tube rack 1 to both sides.
As shown in fig. 1, the rainwater space 7 is provided below the inside of the micro pipe gallery 1, and is used as a rainwater square ditch. The rainwater space 7 can collect rainwater inside the road surface 17 and the present courtyard 22/23 through the gully 26, the rainwater branch 24, and the rainwater branch 25.
The tubulin 1 can adopt different branch port forms according to street pipeline requirements. For the pipeline interface requirements of the present courtyard 22/23 on both sides of the historic cultural neighborhood 21 where the tubulin 1 is laid, the tubulin 1 may take the form of a branching port where the pipeline is individually routed.

Example 2
Referring to fig. 8, the main difference between embodiment 2 and embodiment 1 is that the embodiment 2 accommodates the water supply pipe 8 outside the micro-pipe rack 1 into the micro-pipe rack 1, the water supply pipe 8 is led out without separately making the water supply inspection well 13, and the three-way 41, the valve 39 and the water meter 40 are directly arranged by using the space in the rack. The embodiment 2 is more intensive in the underground space than the embodiment 1, but since the embodiment 2 places the water feed pipe 8 in the rainwater space 7, the water feed pipe 8 may be submerged by rainwater in heavy rain, and there is a risk of pollution of the quality of domestic water. Therefore, in this embodiment 2, it is necessary to ensure that the rainwater space 7 is only rainwater, and no sewage is introduced, and the water supply pipe and the accessories must be completely sealed to prevent rainwater from entering the pipe and polluting water quality. This example 2 is more applicable to projects or areas with high quality construction levels and later operation and maintenance levels.
As a further technical scheme of the invention, other municipal pipelines (such as fuel gas, heat and sewage) which are laid in the historical culture neighborhood 21 and are not included in the micro-pipe gallery 1 can cross the micro-pipe gallery 1 through the sleeve 16 arranged on the pipeline outlet layer 6, so that the problem that other pipelines cross the micro-pipe gallery 1 and are arranged below the micro-pipe gallery 1 to increase implementation difficulty and investment is avoided.
As a further aspect of the present invention, the tubulin cover plate 5 should be provided to be openable and closable at the position of the branching port of the pipeline for pipeline maintenance.
As a further technical solution of the present invention, the water supply inspection well 13 should be a square inspection well, and the dimensions should meet the installation space requirements of the tee 41, the valve 39 and the water meter 40.
As a further technical scheme of the invention, the side wall 2/3, the bottom plate 4 and the cover plate 5 can adopt prefabricated structures, the material is C35 reinforced concrete, and the cover plate can be covered above the side wall in a tongue-and-groove mode; the side walls 2, 3, the bottom plate 4 and the cover plate 5 can also adopt cast-in-place concrete structures, and the materials are C35 reinforced concrete; the material of the electric power bracket (upright post) 11 and the electric power bracket (cross arm) 12 is Q235B; the water supply pipe 8 is made of ductile cast iron pipe; the sleeve 16 may be a steel sleeve (Q235B) or a plastic sleeve (PVC); the rainwater branch lines 24 and 25 and the integrated pipe 36 are made of PVC; the communication sleeves 30 and 31 are made of hot dip galvanized steel pipes; the power bushings 34, 35 are made of CPVC.
In summary, in the related art, there is a problem that urban updating projects of old urban areas such as historical cultural blocks are difficult to meet the direct burying and laying of various municipal pipelines due to street lane stenosis. According to the embodiment of the invention, the microtubule corridor for the narrow street is provided, so that electric power, communication and rainwater pipelines are intensively arranged in the corridor, the water supply pipeline is laid close to one side of the microtubule corridor, and the water supply pipeline inspection well and the microtubule corridor are co-constructed, so that the underground space is greatly saved. Meanwhile, the pipeline outgoing line layer is arranged in the micro-pipe gallery, so that the functions of pipeline outgoing and pipeline crossing are realized on the basis of not expanding the micro-pipe gallery structure, and the problem that other pipelines and the micro-pipe gallery are crossed and arranged below the micro-pipe gallery to increase implementation difficulty and investment is avoided.
