As shown in fig. 1 to 4, the embodiment of the present invention provides an underground utility tunnel, which comprises a pipe gallery body 10, an embedded groove 20 and at least one supporting column 30. The tube lane body 10 includes a top plate 11, a bottom plate 12 and two opposing side plates 13. The embedded groove 20 sets up along the axial extending direction of piping lane body 10, and embedded groove 20 is including setting up the last embedded groove in roof 11 department and corresponding the lower embedded groove that sets up in bottom plate department. At least one support column 30 sets up in piping lane body 10 along vertical direction, and the upper end of support column 30 can be connected with last embedded groove with sliding, and the lower extreme of support column 30 can be connected with lower embedded groove with sliding.

The embodiment of the utility model provides an in support column 30 can slide along embedded groove 20, when needs change the cabin size, can remove this support column 30 and install to settlement position department, can realize the change of cabin size.

Specifically, the embedding slots 20 include at least two upper embedding slots and at least two lower embedding slots, the at least two upper embedding slots are arranged at intervals, and the at least two lower embedding slots correspond to the at least two upper embedding slots in the vertical direction.

Set up a plurality of lower embedded grooves of going up embedded groove and corresponding quantity, can realize the abundant support to the corridor body 10 (every embedded groove can set up a plurality of support columns 30 promptly, and a plurality of embedded groove 20 can set up more support columns 30), and set up a plurality of lower embedded grooves of going up embedded groove and corresponding quantity and can make cabin size adjustment more nimble.

Preferably, at least two upper embedded grooves are symmetrically arranged on two sides of the axis of the pipe gallery body 10. And every goes up the embedding slot all parallel with the axial direction of extension of piping lane body 10, is parallel with the axis of piping lane body 10 promptly.

A refractory partition wall 40 is provided between the support columns 30 and the side plates 13. Along the direction perpendicular to the axis of the pipe gallery body 10, a fire-resistant partition wall 40 is arranged between two adjacent support columns 30.

The fire-resistant partition wall 40 is a light fire-resistant partition wall that can be quickly disassembled and piled, facilitating cabin size replacement and pipeline cross-cabin laying, or allowing a manager to manage or work over the cabin.

The partition wall between the pipe gallery cabins is composed of supporting columns 30 and a fireproof partition wall 40, the fireproof partition wall 40 is built between the two supporting columns 30, and supporting arms for supporting pipelines are directly fixed on the supporting columns 30. The intermediate walls are not subjected to loads other than their own weight (i.e., neither the support columns 30 nor the refractory walls 40 are subjected to the load of the gallery ceiling 11).

The refractory partition 40 may divide the pipe gallery body 10 into a plurality of compartments, for example, as shown in fig. 1 and 3, a first compartment 50, a second compartment 60, a third compartment 70, and a fourth compartment 80 in the left-right direction of fig. 1. The compartments may contain municipal and industrial piping for electricity, telecommunications, water supply, recreational water, heat, natural gas, steam, and the like.

It should be noted that, in the embodiment of the present invention, the supporting column 30 is a steel column, which can be easily detached and installed.

As shown in fig. 1 to 4, the upper and lower pre-buried grooves have the same structure. The installation of the above pre-buried groove is taken as an example, the upper end of the supporting column 30 is correspondingly connected to the upper pre-buried groove through the bolt 31 and the nut 34. Through the cooperation of bolt 31 and nut 34, can realize the purpose of quick installation, be convenient for save installation time, reduce staff intensity of labour.

Further, a sizing block 32 and a spacer 33 are provided between the upper end of the support column 30 and the top plate 11. Set up parallels 32 and gasket 33, can make support column 30 installation more firm, be difficult for taking place the position and remove, and can prevent through setting up parallels 32 and gasket 33 that support column 30 and piping lane body 10 from taking place the damage.
