Embodiment
Fig. 1-9 is please referred to, a kind of tunnel drainage system 100 is present embodiments provided comprising the first drainpipe 110 and more
A second drainpipe 120.
Further, the first drainpipe 110 is longitudinally disposed along tunnel bottom.The setting of multiple intervals of second drainpipe 120.Often
One the second drainpipe 120 is laterally arranged along tunnel bottom.Each second drainpipe 120 connects with the first drainpipe 110
It is logical, at least one inspection shaft 121 is communicated on each second drainpipe 120.
By the way that multiple second drainpipes 120 are arranged, and inspection shaft 121 is set on each second drainpipe 120, so that
The drainpipe quantity of different parts increases in entire tunnel drainage system 100, while difference portion in entire tunnel drainage system 100
The quantity of the inspection shaft 121 of position also increases, and so as to carry out Inspection and maintenance more fully hereinafter to tunnel drainage system 100, has
Conducive to the auditability for improving entire tunnel drainage system 100.
It should be understood that above-mentioned tunnel bottom longitudinally refers to the direction from tunnel portal to another hole, laterally refer to from tunnel
Side lining cutting is to the direction of other side lining cutting；Other understandings should not be done.Further, above-mentioned the second drainpipe being transversely arranged
120 also should not be construed as the two absolute upright with the first longitudinally disposed drainpipe 110, and should be understood that as according to tunnel
Actual conditions trend, above-mentioned the second drainpipe 120 being transversely arranged may right and wrong with longitudinally disposed the first drainpipe 110
It intersects vertically.
Specifically, one end of the well seat 123 of inspection shaft 121 be connected to each the second drainpipe 120 enter water section；
Another end opening of the well seat 123 of each inspection shaft 121 is connected to the water exit end of each the second drainpipe 120.It is each
The water exit end of a second drainpipe 120 is connected to the first drainpipe 110.So that longitudinal row of entire tunnel drainage system 100
Water and transverse drainage are connected together, and form drainage network, improve drainage effect.
Further ,-Fig. 3, an end connector of the well seat 123 of inspection shaft 121 extend behind with from tunnel-liner referring to Fig.1
The second drainpipe 120 connection for entering water direction out, the other end connector of well seat 123 and the second drainpipe of water discharging direction
120 connections, 120 other end of the second drainpipe of water discharging direction and the first drainpipe 110 of tunnel bottom connect.
In one optional embodiment of the application, the first above-mentioned drainpipe 110 is arranged along tunnel bottom center line.It is each

Just.
Specifically, when needing to overhaul, since the inspection shaft 121 on each second drainpipe 120 is that setting exists
In the cable duct 130 of tunnel two sides tunnel-liner, therefore maintenance will not influence the road traffic in tunnel completely.In other words
It says, maintenance can carry out in the case where uninterrupted traffic.When maintenance, maintaining roadway cover board 140 is opened by service personnel, and open
The well lid 122 of inspection shaft 121 is checked and is cleared up to the second drainpipe 120.In another optional embodiment of the application, the
The side of tunnel bottom center line is arranged in one drainpipe 110, is provided with an inspection shaft on each second drainpipe 120
121, and it is located at the other side of center line.Inspection shaft 121 is arranged in tunnel bottom road surface it should be noted that can choose
Or in tunnel side cable duct 130.In the present embodiment, referring to Fig. 4-Fig. 6, the first drainpipe 110 is not or not tunnel bottom road surface
Center, but it is amesiality.At this point, an inspection shaft 121 is only arranged in each second drainpipe 120.And inspection shaft 121
Positioned at the other side of road center line.Still optionally further, it can choose the vertical range of inspection shaft 121 and road center line
It is set as equal with the opposite vertical range of road center line of the first drainpipe 110.D1 in namely Fig. 6 is equal to d2.At this point,
Inspection shaft 121 is not arranged in the cable duct 130 of tunnel two sides tunnel-liner, but in road surface, therefore do not need to be arranged
Two inspection shafts 121 also can be improved the auditability of entire tunnel drainage system 100.
It should be understood that in other optional embodiments of the application, above-mentioned inspection shaft 121 it is vertical with road center line away from
Vertical range d2 from d1 and the opposite road center line of the first drainpipe 110 can select to be set as not phase according to the actual needs
Deng or other relationships.Further, each inspection shaft 121 is arranged in the road surface of tunnel bottom, each inspection shaft
121 well lid 122 is flush to road surface.
By the way that the well lid 122 of each above-mentioned inspection shaft 121 is flush to road surface 160, will not road pavement traffic
It has an impact.
Specifically, inspection shaft 121 is located at road surface or less referring to Fig. 5.The top of inspection shaft 121 is provided with well lid 122
Top flush the bottom with road surface 160.The top of well lid 122 is provided with protection well lid 128 and cage 127, protects well lid
128 are connected to the bottom on road surface.It is pit shaft 124 below well lid 122, the bottom end of pit shaft 124 is connected with well seat 123.Well seat 123 has
There are two ports.It is mounted on connector 125 on two ports, two ports of well seat 123 are connected to second by connector 125
On drainpipe 120.And a port of well seat 123 be connected to the second drainpipe 120 enter water direction, another port is connected to
The water discharging direction of second drainpipe 120.
Still optionally further, it being additionally provided with mud sinking chamber 126 in the bottom end of well seat 123, mud sinking chamber 126 is connected to well seat 123,
