Description
Technical field
The present invention relates to a kind of Tunnel Base gutter structures, and in particular to a kind of to be arranged on Tunnel Base locally buried
Gutter structure.
Background technology
At present, there are two types of modes for Tunnel Base draining：A kind of is that the ponding in tunnel is entered lateral sulcus by abutment wall drain hole,
The Central drain being located in inverted arch filling is introduced from lateral sulcus again, this method is more universal；Another kind is at tunnel bottom setting center
Deeply buried ditch or drain cavern, by outside the direct ejectment to hole of water, this method in Han Qu or the more use of severe cold area Portal Section,
Its situation also has use.Although these drainage systems can smoothly be implemented on all kinds of stratum, and play certain effect, applying
It has also been found that many problems, are mainly shown as during work and operation：
When using first method, sole must enter Central drain by abutment wall drain hole, and Central drain position
In inverted arch filling in, there are tunnel bottom draining it is difficult the problem of, from the point of view of the tunnel runed, when the ponding of tunnel bottom
It can not be successfully when draining, the lighter penetrates into railway roadbed along weak location upwards, and substrate is risen soil, and severe one causes inverted arch to fill and road
Bed cracking floats, and even jeopardizes driving when serious.And when using second method, the water base instinct in tunnel is smoothly arranged
Go out, but the elongated use center Deeply buried ditch in one side tunnel or drain cavern can make project cost remain high；On the other hand, with reference to
Previous construction experience applies center Deeply buried ditch or drain cavern in a wide range of slotting of tunnel bottom, and construction and excavation easily causes just
Phase supporting inverted arch can not be closed in time, also easily cause tunnel arch wall unstability when being excavated using explosion means, greatly increase construction
Risk, while there is also many hidden danger after the completion of constructing.
Since tunnel is a kind of long and narrow structures, often geological conditions variation is frequent, it is necessary to take the buried row in part
Ditch solves the drainage problem of Tunnel Base.
Invention content
The present invention is exactly to solve above-mentioned the problems of the prior art, provides a kind of locally buried draining of Tunnel Base
Ditch structure.
In order to achieve the above object, the present invention adopts the following technical scheme that：
The local buried gutter structure of Tunnel Base of the present invention, including being located at the central drainage pipe in tunnel inverted arch filling
With the multiple inspection shafts set along central drainage pipe length direction；Tunnel Base is provided with the buried gutter in part, and part is buried
The one end in gutter is equipped with end inspection shaft, and end inspection shaft downstream is equipped with charge for remittance well, leads between end inspection shaft and charge for remittance well
It crosses a plurality of vertical aqueduct to connect with a plurality of longitudinal aqueduct, charge for remittance well is connected with central drainage pipe；Tunnel Base ponding is by office
The buried gutter in portion is come together in the inspection shaft of end, then enters charge for remittance well by vertical aqueduct and longitudinal aqueduct, is then led to
It crosses outside central drainage pipe discharge hole.
Central drainage pipe, locally buried gutter and longitudinal aqueduct is consistent with the circuit longitudinal slope gradient.
The central drainage pipe is made of more drainpipes, and crosses end inspection shaft between two parties and in the inspection shaft of end
It does not turn off, the single drainpipe tube coupling length setting charge for remittance well of the central drainage pipe of 1.4 ~ 1.6 times of inspection shaft spaced downstream in end.
Concrete pedestal, the buried gutter in part and concrete pedestal are provided with below the buried gutter in the part
Between using the good coarse sand of water penetration and gravel backfill it is closely knit.Package is permeable on the outside of the steel floral tube that the buried gutter in part uses
Geotextiles install punching bellows in steel floral tube；Steel floral tube top half drills, and 10~16mm of aperture, pitch of holes 10cm are in
Quincuncial arrangement.
It is backfilled to and is put down with central drainage pipe top surface using the good coarse sand of water penetration and gravel in the end inspection shaft
Together, the four corners position of end inspection shaft sets four vertical aqueducts, vertical aqueduct and the charge for remittance well in downstream and center draining
Pipe is connected by longitudinal aqueduct；Vertical aqueduct and longitudinal aqueduct use pvc pipe.
The upstream face side Tunnel Base of the end inspection shaft well bore is poured with lower part using non-fine concrete, with
Just water-collecting capacity is improved.
The invention has the advantages and positive effects that：
The local buried gutter structure of Tunnel Base of the present invention, suitable for Tunnel Base local draining, by tunnel
The buried gutter in substrate setting part and setting end inspection shaft, after the water of substrate is imported end inspection shaft along buried gutter
It is introduced in charge for remittance well through longitudinally, laterally aqueduct and is discharged into Central drain, discharged outside hole, realize self-draining through Central drain
Function so as to reduce the difficulty of construction and risk and project cost of the elongated setting center Deeply buried ditch in tunnel or drain cavern, subtracts
The water pressure that structure during small constructing tunnel and during operation is born prevents tunnel from being served as a contrast during construction period and operation
It builds structural percolating water and even causes Lining cracks, ensure operation security.

Specific embodiment
To the Tunnel Base of the present invention, locally buried gutter structure is done further in the following with reference to the drawings and specific embodiments
Explanation.Following each embodiments are merely to illustrate the present invention and not limitation of the present invention.
The local buried gutter structure of Tunnel Base of the present invention, suitable for Tunnel Base local draining.The discharge structure
It takes in the buried gutter of Tunnel Base local setting, setting end inspection shaft and charge for remittance well, by the water of substrate along buried draining
Ditch is discharged into Central drain after importing end inspection shaft in longitudinally, laterally aqueduct introducing charge for remittance well, and hole is discharged through Central drain
Outside.
Fig. 1 is the longitudinal section view of the local buried gutter structure of Tunnel Base of the present invention；Fig. 2 is the tunnel base of the present invention
The vertical view in the local buried gutter in bottom.As depicted in figs. 1 and 2, the local buried gutter structure of Tunnel Base of the invention, packet
The setting central drainage pipe 1 in tunnel inverted arch filling is included, in the buried gutter 2, Duo Gejian in the part of Tunnel Base local setting
Look into 3, end inspection shafts 4 of well, a charge for remittance well 5, a plurality of vertical aqueduct 6 and a plurality of longitudinal aqueduct 7.Central drainage pipe
The Tunnel Base part of 1 lower section is provided with the buried gutter 2 in part.The buried gutter 2 in part is adapted to using non-totally-enclosed anti-
The tunnel of water, mainly suitable for be arranged on tunnel trunk country rock be rich water Quaternary Strata, tertiary stratum, soft rock strata and ground
Matter structural belt；In addition, change of properties section also has certain adaptability after meeting water for rich water ground consisting of hard rock substrate.
Inspection shaft 3 is set along 1 length direction of central drainage pipe, and an inspection shaft is set per 30m.The buried gutter 2 in part
Interior water flows into the end inspection shaft 4 of low side setting.Water in end inspection shaft 4 is vertical by four vertical aqueducts 6 and two
It is discharged outside hole through central drainage pipe 1 after the inflow charge for remittance of aqueduct 7 well 5, realizes self-draining function.
Central drainage pipe 1, the buried gutter 2 in part and two longitudinal aqueducts 7 and the tunnel inner orbit circuit longitudinal slope gradient
Unanimously.
Central drainage pipe 1 is made of more drainpipes, and cross between two parties end inspection shaft 4 and in end inspection shaft 4 not
