This utility model for achieving the above object, is achieved through the following technical solutions: major long tunnel counter-slope Auto-drainage system
System, including several sumps arranged along length of tunnel direction, sump is all opened in tunnel bottom, and each sump top sets
Putting well lid, well lid is offered several through hole, well lid can close sump top, arranges water filtering tank, water filtering tank side in sump
Several filter opening is offered on wall top, arranges level measurement device, the first suction pump and one end of drain pipe, level measuring in water filtering tank
Device and the first suction pump connect, and the first suction pump is connected with drain pipe, and the other end of drain pipe is positioned at the collection of adjacent high-land
In well.
For realizing the purpose of this utility model further, it is also possible to by the following technical solutions: set in described water filtering tank
Putting the second suction pump, the second suction pump is connected with level measurement device, and the second suction pump is connected with drain pipe；Described drain pipe
On connecting tube is set, connecting tube connects check-valves and butterfly valve；The described through-hole diameter on well lid is not more than 10mm；Described
Filter opening diameter is not more than 5mm；Signal transmitting apparatus is connected on the first described suction pump；Letter is connected on the second described suction pump
Number transmitting device；Distance bottom described filter opening and sump is 500-800mm..
The utility model has the advantage of: in this utility model, sump arranges well lid, cancel existing guard rail
Bar, increases vehicle and machinery passage space in hole, does not affect main equipment turnover.During draining, water first passes through well lid and arrives
In sump, well lid is provided with through hole, is equivalent to water has been carried out primary filter；After water entrance sump after precipitation filters
Entering in water filtering tank by the filter opening above water filtering tank again, water quality is filtered by second time；Water after filtration passes through water level
Measurement apparatus controls to start the first suction pump, is drained into by water in the sump of adjacent high-land, drains into the most step by step outside hole.This
Structure avoids water filtering tank inner accumulated foreign material, prevents foreign material from entering the first suction pump and makes the first suction pump break down.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Reference: 1 sump 2 first suction pump 3 water filtering tank 4 well lid 5 drain pipe 6 connecting tube 7 check-valves 8
Butterfly valve 9 second suction pump 10 filter opening 11 ball-cock assembly 12 tunnel.
Detailed description of the invention
Major long tunnel counter-slope automatic drain system, as it is shown in figure 1, include several along catchmenting that tunnel 12 length direction is arranged
Well 1, sump 1 is all opened in bottom tunnel 12, and each sump 1 top arranges well lid 4, and well lid 4 is offered several through hole,
Well lid 4 can close sump 1 top, arranges water filtering tank 3 in sump 1, and water filtering tank 3 side wall upper part offers several filter opening 10,
Level measurement device, the first suction pump 2 and one end of drain pipe 5, level measurement device and the first suction pump are set in water filtering tank 3
2 connect, and the first suction pump 2 is connected with drain pipe 5, and the other end of drain pipe 5 is positioned at the sump 1 of adjacent high-land.Well lid 4
Bearing capacity more than the maximum weight that may carry.Sump 1 arranges well lid 4, cancels existing guard rail, increase
Vehicle and machinery passage space in big hole, do not affect main equipment turnover.Level measurement device can be ball-cock assembly 11, water level
The various structures such as sensor.During draining, water first passes through well lid 4 and arrives in sump 1, and well lid 4 is provided with through hole, and it is right to be equivalent to
Water has carried out primary filter；Water enters filter by the filter opening 10 above water filtering tank 3 after entering sump 1 after precipitation filters again
In water tank 3, water quality is filtered by second time；Water after filtration controls to start the first suction pump 2 by level measurement device,
Water is drained in the sump 1 of adjacent high-land, drain into the most step by step outside hole.Such a configuration obviates water filtering tank 3 inner accumulated miscellaneous
Thing, prevents foreign material from entering the first suction pump 2 and makes the first suction pump 2 break down.
Arranging the second suction pump 9 in described water filtering tank 3, the second suction pump 9 is connected with level measurement device, and second draws water
