Description
Technical field
This utility model relates to traffic tunnel technical field, is specifically related to a kind of row of tunnel bottom in rich water lithostratigraphy
Water-bound.
Background technology
Tunnel is a kind of underground structure that the industries such as railway, highway, city underground, water conservancy, electric power and national defence generally use,
It is mainly used in current vehicle, conveying goods and materials and pedestrian etc..The various rocks below earth's surface or soil ground generally to be built in tunnel
In the middle of layer.For the tunnel built in rock mass or pedostratigraphy, different types of because rock mass or soil there are
Lower water, therefore subsoil water can produce impact to the construction in tunnel and operation.High especially for level of ground water and water content big or
For the sufficient stratum of person's recharge of ground water, the emission problem of underground water in tunnel when building tunnel wherein, have to be considered.
Generally when subterranean tunnels such as railway construction, highway, city underground and defence engineerings, for preventing ground water discharge the most smooth
And affect the long-term safety operation in tunnel, in tunnel, need to be configured to the discharge-channel of lower water.General way is exactly at tunnel
On road base plate, both sides or single-side drainage ditch are set near arch springing position, tunnel-liner left and right.By in tunnel by construction of concrete lining
The subsoil water staying the position such as the osculum set and lining cutting weak link to ooze out on seam or lining cutting or to be flowed in tunnel is pooled to two
In the gutter of side or one side, and drained into outside hole by it.Although this way cost is low, but can only be without subsoil water or ground
Use when the stratum that lower water content is smaller is built tunnel.
And for the bigger stratum of subsoil water content, especially rich in the stratum of subsoil water, due to the supply of subsoil water in stratum
Abundant with source, when building tunnel wherein, the excess of subsoil water is penetrated into or is flowed into and can transport tunnel structure and long-term safety thereof
Battalion's generation has a strong impact on.One side or the Normal practice in gutter, both sides are set on tunnel floor if still used, it is difficult to row
Except penetrating into a large amount of subsoil water in tunnel, time serious, also affect the safe operation in tunnel.Additionally, on tunnel floor
Both sides or one side time gutter is set, owing to the elevation in gutter is consistent with tunnel floor elevation, when a large amount of subsoil water in rainy season
When penetrating into tunnel, the silt in stratum can be brought in gutter by subsoil water, and then silt can deposit in gutter and can block up
Plug gutter, causes subsoil water to overflow in gutter and have influence on the safe operation in tunnel.Especially to being in extremely frigid zones
Traffic tunnel for, when underground water in tunnel drainage difficulty or during overflow everywhere in tunnel, subsoil water will be at tunnel in winter
Freeze in road, and then influence whether vehicle and the safe passing of pedestrian in tunnel.
Along with China Express Railway, highway and the fast development of the underground engineering such as city underground and defence engineering, tunnel
Engineering will be used in traffic network in a large number, and therefore the probability in Tunnel Passing water rich strata also will certainly increase.And pass
The tunnel internal drainage way of system can not adapt to tunnel drainage and the needs of safe operation in water rich strata, it is therefore desirable to seeks
Seek a kind of new structure being suitable in water rich strata collecting and get rid of subsoil water in tunnel.

Flow to rhone under the effect of deadweight, will not accumulate on the base plate in tunnel, being dried and cleaning, no of tunnel floor can be kept
Improve only the operating environment in tunnel, but also reduce the labor intensity of pump drainage subsoil water, it is possible to decrease take out during tunnel operation
The maintenance cost of row's subsoil water.
Additionally, during tunnel is runed for a long time, even if the rhone section of tunnel bottom is blocked by mud, can be by being arranged on button
Groove section is rinsed and clears up by the spilled water hole on plate, it is possible to cleared up as inspection shaft by the spilled water hole on buckle, it is simple to
Keep the smooth and easy of rhone section draining.Compared with conventional drainage pattern, discharge structure of the present utility model not only reduces clearly
In reason rhone, the labor intensity of mud, also can reduce the expense of water-pumping/draining.Further, since subsoil water is along at the bottom of less than tunnel
Flowing in the bottom rhone of plate hight journey, even if the temperature in tunnel reduces, for the tunnel being in extremely frigid zones, tunnel
Owing to being provided with heat-insulation layer below road base plate, therefore under the effect of heat-insulation layer, the temperature in rhone will not reduce, thus
Subsoil water in groove will not freeze, and rhone by ice blockage, thus would not can be further ensured that extremely frigid zones water rich strata
In tunnel in the winter time period safe operation.
Additionally, due to rhone is placed in the rock mass of tunnel bottom, the rock mass around groove section has higher intensity, and it can
Support and prevent groove section from sinking, in order to making full use of and play the bearing capacity of rock mass itself.The buckle of rhone section, abutment wall
Can be according to vehicle current in the flow of underground water in tunnel, tunnel, pedestrian or other special loads through meter with base plate thickness
Calculate and determined, it is simple to meet tunnel and pass through vehicle or undertake the needs of other special loads, there is stronger adaptability.
Therefore, the discharge structure of tunnel bottom in rich water lithostratigraphy described in the utility model, have compact conformation,
Drainage effect is good, load-carrying properties are high, convenient construction, cost and the relatively low feature of maintenance cost, and range is wide.
