As depicted in figs. 1 and 2, underground pipe gallery includes by the circumferential assembled unit of unit sheet bar 1 in the present invention
Tube coupling 2, that is, feed intake storehouse, which collectively forms pipe gallery along axial direction and other pipeline section assembly of pipe gallery；This feeds intake
The structure type in storehouse is consistent with the prover section piping lane used on the market, but for the ease of the serial of pipeline, personnel pass in and out space,
Monitoring, measurement and the concentration laying for counting equipment of its pipeline compartment, the structure size in the storehouse that generally feeds intake is relative to standard pipe
Section piping lane can be larger.
Be located at top surface unit sheet bar on open up feeding port 3 in advance, the feeding port 3 have can meet pipeline, equipment, people
The port size of member's disengaging size, and in the setting of the surrounding of the feeding port 3 for reinforcing orifice structure and connecting external structure
Transition fashioned iron 4.As shown in Figure 3 and Figure 5, during the connection type of transition fashioned iron 4 and feeding port surrounding is welding, bolt, rivets
At least one preferably bolts.The structure of transition fashioned iron 4 can be selected according to aperture position and shape, and transition fashioned iron 4 can be I-shaped
Steel, plain plate, curved plate, channel steel, H profile steel, angle steel, square steel, deformed steel etc..The present invention is in the unit sheet bar for being located at top surface
Surface on open up meet pipeline, equipment, personnel pass in and out the aperture of size, and used fashioned iron to be reinforced at one the week of aperture,
And fashioned iron is also used as the superstructure of flange and feeding port to connect；It is laid with and repairs convenient for piping lane internal unit simultaneously.
The fashioned iron 5 for being connected with ground installation is also connected on above-mentioned transition fashioned iron 4, which is located at throwing
Above material mouth surrounding.The lower end of the fashioned iron 5 has the lower flange being connected with transition fashioned iron 4, specific fashioned iron 5 and transition fashioned iron
4 are bolted or weld；The upper end of the fashioned iron 5 has the upper flange being connected with ground installation, which is plane
Flange arrangement, as shown in Figure 5.Connection fashioned iron in the chamber structure that feeds intake not only acts as the effect for further reinforcing aperture, also makees
It feeds intake the connection transition piece of structures for feeding port and ground, realizes the connection between underground and surface infrastructure.
As shown in Figure 1 and Figure 5, above-mentioned feeding port 3 is offset to the side in the storehouse axial centre face that feeds intake, wherein in axial direction
The fashioned iron 5 in heart face be one axially through the storehouse that feeds intake carrying girder steel, the fashioned iron 5 close to the side of unit sheet bar is one along feeding intake
The shape steel rolled stock of mouth edge setting, other two is used to connect carrying girder steel and shape steel rolled stock, along the type of feeding port edge setting
Steel 5 is I-steel or plain plate.Feeding port is to bear top close to the side for throwing storage hopper center, the i.e. feeding port in the present invention
Pressure bear again side plate transmitting thrust, added again on side fashioned iron of the feeding port close to axial centre face one axially through
The carrying girder steel in storehouse of feeding intake can further enhance the weakness of feeding port as connection fashioned iron, improve integrally-built intensity；
And the both ends of the carrying girder steel are respectively placed on the unit sheet bar of top surface, in the load transmission to unit sheet bar that can be born,
Reduce the compacting to feeding port.
As shown in Figure 3 and Figure 4, said units plate 1 be with cambered corrugated sheet steel, the storehouse that feeds intake inner wall,
It is equipped with and the consistent steel pipe 6 of corrugated sheet steel radian in the trough of corrugated sheet steel.Trough on adjacent cells plate 1 correspond and
Circumferential connection forms annular trough, and the annular steel ring of the end to end formation of steel pipe 6 in the annular trough.For entirely by waveform
The assembled unit pipes section structure of steel plate can be spaced or all corrugated sheet steels to increase integrally-built stabilization and intensity
Trough in lay the steel pipe 6 that be bonded with corrugated sheet steel, and the one or multi-channel annular steel ring of formation.When corrugated sheet steel is arc panel
When piece, the radian for the steel pipe 6 being arranged in trough is consistent with arc panel radian, and steel pipe 6 and corrugated sheet steel 6 constitute and be similar to steel
Arch frame structure, so as to which integrally-built strength and stability is greatly improved.
Further for enhancing integrally-built stability, can in steel pipe 6 fill concrete, or be arranged in steel pipe 6
Reinforcing bar and fill concrete, armored concrete can be with the stress together of steel pipe 6.In addition the load that above-mentioned connection fashioned iron is born can pass
It is handed on the fashioned iron by being connected with it and the steel pipe of unit sheet bar inner wall setting, wherein setting reinforcing bar or reinforcing bar are mixed in steel pipe
Solidifying soil, using steel pipe be arranged circumferentially and the common stress of pipeclay so that the bearing capacity of total is protected well
Barrier.
As shown in Figure 3 and Figure 5, it draws and is equipped with for alleviating local stress collection at aperture between transition fashioned iron 4 and piping lane inner wall
In pull rod 7.Pull rod 7 can be connected directly between on the storehouse that feeds intake between the bolt of transition fashioned iron 4 and the internal-flange bolt of unit tube coupling, or
Support is arranged on unit tube coupling inner wall in person, draws between support and transition fashioned iron 4 and sets pull rod 7.At feeding port of the invention
Stress is weak, and filled load, which is continuously increased, to be more easily damaged, and draws between fashioned iron and piping lane inner wall and sets pull rod, hole can be effectively relieved
Stress raisers phenomenon at mouthful adapts to high roadbed operating condition convenient for piping lane.
The present invention bin structure that feeds intake is simple, manufacture easy to process, strong operability, using precast splice type pattern,
Construction is fast and construction speed is secure, and fabrication and installation process is simple, low relative to concrete component production, installation cost, tool
There is good economic benefit.
