Drainage ditch 12 will not be blocked by putting 14 rear support structure 14 of supporting structure, the ponding in electric power tunnel 11 is discharged into drainage ditch
12, set double-edged fine-toothed comb 16 that personnel are easily walked in electric power tunnel 11 at the top of drainage ditch 12.
Pumping channel 13 has the effect of assisted drainage, can be quickly by electric power tunnel 11 with reference to the use of drainage ditch 12
Ponding discharge.Pumping channel 13 is excavated from ground, is constructed with the mode of rotary digging, and the bottom of pumping channel 13 connects after construction
Inside logical electric power tunnel 11, pumping equipment is set on ground, and pipeline is taken out certainly when alloing 11 internal water accumulation of electric power tunnel serious
Aquaporin 13 is stretched into electric power tunnel 11, quickly can be drained ponding by pumping equipment, it is ensured that electric power in electric power tunnel 11
The safety of equipment.
Supporting block 15 is arcuate structure, and the side wall for being fixed on electric power tunnel 11 forms supporting structure 14 so that electric power tunnel
Road 11 is more firm, and power equipment can have good protecting effect.
The electric power tunnel 11 obtained by this construction method has the characteristics that reasonable in design, drainage efficiency is high.If
The effect of Quick drainage can be played by putting the drainage ditch 12 in 11 bottom of electric power tunnel, be arranged on drawing water for the top of electric power tunnel 11
Passage 13 can carry out assisted drainage when drainage ditch 12 is filled and has little time draining, it is ensured that 11 internal water accumulation of electric power tunnel is quick
Discharge, makes power pipe have good working environment.
As shown in Figure 1, the bottom nozzle in pumping channel 13 sets adapter 17, the side wall and supporting block 15 for making adapter 17 are fixed
Connection, and set at adapter 17 and be detachably connected with it and the plug 18 of 17 sealings can be will take over.
The setting of adapter 17 facilitates drinking-water pipe to stretch into inside electric power tunnel 11, and plug 18 is set at adapter 17, makes plug
18, which will take over 17 ports, blocks, without using when impurity is not entered inside electric power tunnel 11 out of pumping channel 13.
As shown in Figures 2 and 3, it is laid with after supporting structure 14 in extension side of the side wall along electric power tunnel 11 of electric power tunnel 11
To the multiple supporting items 19 of interval setting；Supporting item 19 includes substrate 20 and multiple support plates 21, and substrate 20 is arc, 20 edge of substrate
Vertically it is connected in supporting block 15, support plate 21 is slab construction, and each support plate 21 is horizontally disposed on the base plate 20, Duo Gezhi
Fagging 21 is vertically arranged at intervals, and support plate 21 is set towards the middle part of electric power tunnel 11 and perpendicular to the axis of electric power tunnel 11
Put；
Side wall after setting supporting item 19 in electric power tunnel 11 sets sliding equipment, and sliding equipment includes slide 22 and sliding block 23,
Slide 22 is arranged in supporting block 15 and is set along the extending direction of electric power tunnel 11, and slide 22 is arranged on multiple supporting items 19
Top, and the middle part of slide 22 is close to the plug 18；Sliding block 23 is slidably disposed on slide 22, the sidepiece of sliding block 23
Connecting seat 24 is provided with, is provided with connector 25 on connecting seat 24, connecting cantilever 26 on connector 25, the end connection of cantilever 26
17 connector of pipe；The connector 25 is rotatablely connected with connecting seat 24 enables connector 25 to be rotated around vertical axis, described
Cantilever 26 is rotatablely connected with connector 25 enables cantilever 26 to be rotated around horizontal axis, can be connected on the pipe fitting 27
Pipe 17, the length of the cantilever 26 are more than the length of the support plate 21.
Set supporting item 19 power pipe is laid with along support plate 21, make to be laid with electric power tunnel 11
More power pipes, while enable ground of the power pipe away from electric power tunnel 11, away from ponding；Skate machine is set at the same time
Structure enables drinking-water pipe conveniently to connect, work progress of conveniently drawing water, while the structure setting of sliding equipment is not so as to
Influenced, can normally be worked by multiple supporting items 19 that the inside of electric power tunnel 11 is set.
Multiple support plates 21 are set on each supporting item 19, multiple supporting items 19 complement each other to form Multi-layer supporting layer,
Make that more power pipes can be accommodated inside electric power tunnel 11.The substrate 20 of arc is conveniently connected to the supporting block 15 of arcuate structure
On, the support plate 21 of slab construction facilitates the placement of pipeline.
Sliding equipment is arranged on the top of supporting item 19, and sliding block 23 can be slided relative to slide 22.The middle part of slide 22
Close to plug 18, sliding block 23 is easier have wider array of moving range close to drinking-water pipe, drinking-water pipe when making to draw water, and draw water operation model
Enclose bigger.
When in use, drinking-water pipe is extended to inside electric power tunnel 11 from pumping channel 13, and the end of drinking-water pipe is connected
On pipe fitting 27.Connecting seat 24 is used to connect miscellaneous part, and connector 25 can rotate, and cantilever 26 can be driven to rotate
And changing the direction of cantilever 26, cantilever 26 enables 26 end position of cantilever to change with the rotation connection of connector 25.

End makes cantilever 26 consistent with the direction of support plate 21, since 26 length of cantilever is more than towards the center of electric power tunnel 11
21 length of support plate, makes the position of pipe fitting 27 and drinking-water pipe and the position of support plate 21 non-interference, is moved through in sliding block 23
It will not influence each other between each component in journey.Rotation connection first 25 and cantilever 26 make to draw water after sliding block 23 is moved to suitable position
Pipe is towards ponding position and carries out work of drawing water.
Ponding is not easy to flow when ponding is shallower, by setting sliding equipment quickly and easily to change drinking-water pipe
Position, so as to provide guaranteeing role for Quick drainage, staff is reduced the underground construction activity duration, be also work
The health for making personnel provides guarantee.
The pipe fitting 27 is connected with 26 flexural pivot of cantilever.Flexural pivot connection relation enable pipe fitting 27 direction more
Optionally rotate.
As shown in figure 4, the pipe fitting 27 includes the intermediate plate 28 of two arcs, at least one intermediate plate 28 being capable of activity.It is logical
The setting for crossing this structure enables pipe fitting 27 is more convenient to be quickly clamped drinking-water pipe, and quickly changes drinking-water pipe
The direction of end.
The intermediate plate 28 forms for sheet metal bending.
The pumping channel 13 causes the top of pumping channel 13 to deviate the bottom of pumping channel 13 for incline structure.Tilt
The pumping channel 13 of setting enables the structure of electric power tunnel 11 to keep more firm, and the water extracted out is not easily penetrated into electricity
In power tunnel 11.
The top of the pumping channel 13 is connected with the end cap 29 being detachably connected with it.End cap 29 coordinates plug 18, makes
Impurity is not easily accessed in electric power tunnel 11.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or use the present invention.
A variety of modifications to these embodiments will be apparent for those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, it is of the invention
The embodiments shown herein is not intended to be limited to, and is to fit to and the principles and novel features disclosed herein phase one
The most wide scope caused.
