Description
Technical field
The present invention relates to a kind of Tunnel Base waterways structure, it is specifically related to a kind of be arranged on the buried waterways structure in Tunnel Base local.
Background technology
At present, Tunnel Base draining has two kinds of modes: a kind of is that by limit wall weep hole, the ponding in tunnel is entered lateral sulcus, then introduces the Central drain being positioned at inverted arch and filling from lateral sulcus, and this kind of method is comparatively general; Another kind arranges center Deeply buried ditch or sluicing hole at the bottom of tunnel, by direct for water ejectment to, outside hole, this kind of method is in Han Qu or the more employing of section of hole, severe cold area, and other situation also has employing. Although these water exhaust system all can be implemented smoothly on all kinds of stratum, and play certain effect, but also find many problems in construction and operation process, mainly show as:
When adopting the first method, substrate water must enter Central drain by limit wall weep hole, and Central drain is positioned at inverted arch filling, there is the problem of tunnel bottom draining difficulty, from the tunnel runed, when the ponding of tunnel bottom cannot be drained smoothly, the lighter upwards infiltrates railway roadbed along weak location, substrate is risen soil, and severe one causes inverted arch to fill and railway roadbed cracking, floating, even jeopardizes driving time serious. And when adopting the 2nd kind of method, the water in tunnel can be discharged substantially smoothly, but tunnel elongated employing center Deeply buried ditch or sluicing hole can make construction costs remain high on the one hand; On the other hand, in conjunction with conventional construction experience, center Deeply buried ditch or sluicing hole is applied in tunnel bottom slotting on a large scale, construction and excavation easily causes initial stage supporting inverted arch to close in time, also tunnel arch wall unstability is very easily caused when adopting explosion means to excavate, greatly increase construction risk, after having constructed, also there is many hidden danger simultaneously.
Owing to tunnel is a kind of long and narrow structures, often geologic condition change is frequent, it is necessary to take buried waterways, local to solve the drainage problem of Tunnel Base.
Summary of the invention
The present invention is exactly to solve above-mentioned the problems of the prior art, it provides buried waterways, a kind of Tunnel Base local structure.
In order to achieve the above object, the present invention adopts following technical scheme:

Embodiment
Below in conjunction with the drawings and specific embodiments, buried waterways, the Tunnel Base local structure of the present invention is described further. Following each embodiment is not only limitation of the present invention for illustration of the present invention.
Buried waterways, the Tunnel Base local structure of the present invention, is applicable to Tunnel Base local draining. This discharge structure is taked to arrange buried waterways in Tunnel Base local, arrange end inspection chamber and remittance well, the water of substrate is introduced in remittance well through longitudinal, horizontal aqueduct after the inspection chamber of remittance end, buried waterways and enters Central drain, discharge outside hole through Central drain.
Fig. 1 is the longitudinal section of buried waterways, the Tunnel Base local structure of the present invention; Fig. 2 is the vertical view in the buried waterways, Tunnel Base local of the present invention. As depicted in figs. 1 and 2, buried waterways, the Tunnel Base local structure of the present invention, comprise tunnel inverted arch fill in central drainage pipe 1 is set, in the buried waterways 2, local that Tunnel Base local is arranged, multiple inspection chamber 3, end inspection chamber, 4, remittance well 5, many erect to the longitudinal aqueduct 7 of aqueduct 6 and many. Tunnel Base part below central drainage pipe 1 is provided with buried waterways 2, local. Buried waterways 2, local is adapted to adopt the tunnel of non-totally-enclosed waterproof, is mainly suitable for being arranged on Quaternary system stratum, Tr stratum, soft rock strata and geological structural belt that tunnel barrel country rock is rich water; In addition, after meeting water for rich water ground consisting of hard rock substrate, change of properties section also has certain adaptability.
Inspection chamber 3 is the setting of water shoot 1 length direction centrally, and every 30m arranges an inspection chamber. Water in buried waterways 2, local flows into the end inspection chamber 4 that low side is arranged. Water in end inspection chamber 4 is erected by four after flowing into remittance well 5 to the longitudinal aqueduct 7 of aqueduct 6 and two discharges outside hole through central drainage pipe 1, it is achieved self-draining function.
Central drainage pipe 1, buried waterways 2, local aqueduct 7 longitudinal with two are consistent with the vertical slope of track circuit in the tunnel gradient.
Central drainage pipe 1 is made up of many water shoots, and crosses end inspection chamber 4 between two parties and do not disconnect in end inspection chamber 4, and namely the water of central drainage pipe 1 does not enter end inspection chamber 4. Central drainage pipe list root water shoot pipe joint length end inspection chamber 4 spaced downstream 1.4 ~ 1.6 times arranges remittance well 5.
