Description
Technical field
The invention belongs to Tunnel Engineering technical fields, drain more particularly, to a kind of bridge tunnel abutting lot tunnel portal
System.
Background technique
China is man of a Ge Duo mountain country, and general hillside is precipitous in mountain area, narrow space, recently as the fast of China's high speed
Speed development, the adjacent phenomenon of bridge tunnel are inevitable.The mountain area of Tunnel Passing, underground water are also various to the harm in tunnel.It
Not only increase tunnel difficulty of construction, reduce construction quality, and with various operation waste water collective effects, be to endanger tunnel structure
The principal element of durability.On the other hand, if the phenomenon that tunnel structure or road surface are with the presence of percolating water, will greatly reduce tunnel
The service life and function of various facilities in road deteriorate the operation condition in tunnel, induce traffic accident.It is leaked in Layers In Cold-area Tunnels
Water will also be such that tunnel road surface freezes, and top generates icicle and invades boundary, jeopardize traffic safety.In addition, the processing of construction period guarded drainage is not
Good, plugging operation when by operation brings great trouble.Maintenance cost is high, and construction interference is big, influences normally to operate, and
Often plugging effect is poor, gets half the result with twice the effort.To avoid tunnel from building up the various leakage problems that operation occurs in the process, extend tunnel
Service life, it is ensured that traffic safety, processing guarded drainage problem is just particularly important ahead of time in the construction process.
When encountering mountain terrain in the design at present, generally shortens the length in tunnel and bridge as far as possible, pass through between bridge tunnel
Short-circuit base transition, this way violate the principle in tunnel " early into evening go out ", and traditional hole ditch only have tunnel lateral sulcus or in
Edema with the heart involved ditch, this traditional hole drainage system drainage effect is poor, when water is larger, be easy to cause hole underground water, maintenance is tired
Difficulty be easy to cause and washes away to abutment and beam, and tunnel sewage is expelled directly out outside hole, is unfavorable for environmental protection.
Consider the structural particularity of abutment and beam, to guarantee that it uses the globality of function and structure, is used in tunnel only
Vertical drainage system, effectively improves hole drainability, enables outside the smooth discharge hole of the underground water collected in tunnel, guarantees
The smoothness of safety and the draining of operation phase of constructing tunnel, and it is convenient for operation phase repair and maintenance.
Summary of the invention
Aiming at the above defects or improvement requirements of the prior art, the present invention provides a kind of bridge tunnel abutting lot tunnel portal row
Water system, the first drainage cell and packet that setting connect blind pipe, turns to drainpipe outside well and hole including ditch, lateral sulcus with steering well
Include Central drain, transverse drain, the second drainage cell for turning to drainpipe outside well and hole.First drainage cell is used for tunnel not
By outside the underground water ejectment to hole collected in tunnel when being arranged or being not easy to be arranged Central drain, the second drainage cell is used for tunnel
It will be outside the underground water ejectment to hole collected in tunnel in conjunction with the first drainage cell when Central drain is set.Suitable for lateral sulcus draining or
The Central drain tunnel drainage system of lateral sulcus and Central drain draining, Central drain is parallel with the ditch of two sides and its width is greater than
The upper surface in the ditch of two sides, Central drain is equal with center sump, and the underground water in Central drain is directly entered center collection
Well, then introduced by transverse drain and turn to well, it is arranged finally by drainpipe ejectment to earth's surface outside the hole being arranged in well is turned to
Water system avoids underground water directly washing away to bridge.
To achieve the goals above, a kind of bridge tunnel abutting lot tunnel portal drainage system is provided, including is uniformly set to tunnel
End wall is arranged in several ditches of road two sides, hole, which is characterized in that the drainage system further includes turning to well, outside hole
Drainpipe, lateral sulcus connect blind pipe, center sump, transverse drain and Central drain with well is turned to；
The steering well is set to hole platform down either side, the ditch and the steering well and passes through an inclination arrangement
The lateral sulcus connect blind pipe connection with well is turned to, it is described to turn to well drainpipe outside the setting hole of the side of bridge, with
The first drainage cell for connecting blind pipe with steering well including the ditch, lateral sulcus, turning to drainpipe outside well and hole is formed, is used for
Tunnel is not provided with or is not easy to will be outside the underground water ejectment to hole collected in tunnel when Central drain is arranged；
The center concentrates well to be set to tunnel face center, and lower end two sides are equipped with through-hole, described transverse drain one end
It is connect with the center sump, the other end is connected to the steering well, includes the Central drain, transverse drainage to be formed
Pipe, the second drainage cell for turning to drainpipe outside well and hole are used to combine the first drainage cell when tunnel setting Central drain
It will be outside the underground water ejectment to hole collected in tunnel.
It further, further include that lateral sulcus connect blind pipe with center sump, the ditch passes through with the center sump
The lateral sulcus connect blind pipe with center sump and is connected.
Further, the transverse drain is located at the underface that the lateral sulcus connect blind pipe with center sump.
