Description
Technical field
The utility model belongs to municipal works city tunnel structure-design technique field, and in particular to one kind is in tunnel
The percolating water ejectment structure of wall.
Background technique
City tunnel can effectively improve road passage capability, alleviate urban traffic pressure, and than elevated bridge occupied space
Less, small to the influence of environment.With the development and utilization of urban underground space, the underground trend increasingly significant of means of transportation, city
City tunnel will more enter people's lives.
Although the design and construction technology of city tunnel are more mature, anti-row's problem of tunnel structure percolating water is still
It is the emphasis and difficult point in design and construction.Tunnel structure waterproof system include concrete structure self-waterproofing, outer waterproofing layer and
The thin portions water proof structure such as deformation joint, construction joint, wall pipe, built-in fitting.Although all taking much count of tunnel in design and construction overall process
Waterproof and water drainage system, but percolating water phenomenon or inevitable, all possible generation in the positions such as waterproof layer, detail structure in Practical Project
Different degrees of percolating water.
Tunnel structure percolating water causes humid environment in tunnel, shortens the service life of tunnel auxiliary facility, increases maintenance
Expense.It will lead to concrete structure damage, road surface large area ponding in tunnel when percolating water is serious, not only influence traffic safety,
The service life of structure can also be reduced.
City tunnel generally uses armored concrete single hole or multiple box culvert structure, and box culvert structure is by top plate and bottom plate, side wall
And middle wall (multiple box culvert) composition.Along the longitudinally disposed maintaining roadway in tunnel and gutter, the bottom Zhong Qiang is vertical along tunnel for side wall bottom
To setting anticollision kerbstone.Fig. 1 show typical diplopore box culvert structure cross section.
At present in engineering, common anticollision kerbstone and flat stone (A drawing), maintaining roadway and gutter (B drawing)
As shown in Figure 2 and Figure 3.When percolating water occurs for the detail structures such as tunnel structure waterproof layer, deformation joint, therefrom wall flows down meeting to percolating water
It covers anticollision kerbstone A1 to arrange by flat stone A2 to tunnel road surface, then is discharged into the longitudinal drainage gutter in tunnel by acclive road surface
In B2, drainage pattern inorganization is random.Middle wall percolating water by effective Path-collection and cannot be discharged into the drainage system in tunnel
It is interior, appearance quality inside and outside tunnel is influenced, traffic safety hidden danger may be brought, therefore, timely and effectively excludes the percolating water in tunnel
It is very necessary.
Utility model content
The purpose of this utility model is that: a kind of percolating water ejectment structure for wall in tunnel is provided, existing tunnel is solved
Wall percolating water cannot be by effective Path-collection and the problem of be discharged into the drainage system in tunnel in road.
The technical solution adopted in the utility model is as follows:
A kind of percolating water ejectment structure for wall in tunnel, including along length of tunnel direction and the bottom Zhong Qiang being arranged in
Anticollision kerbstone is provided with flat stone by anticollision kerbstone, be provided at the top of anticollision kerbstone it is longitudinal receive ditch, it is longitudinal to receive ditch longitudinal slope and tunnel
Road longitudinal slope is consistent, and anticollision kerbstone outer surface is provided with several drain measure ditches, is provided on the flat stone by anticollision kerbstone bottom
Longitudinal flat stone gutter, longitudinal flat stone gutter longitudinal slope are consistent with tunnel longitudinal slope.
Further, 10m is divided between adjacent two sections of drain measure ditches.
Further, drain measure ditch is the semicircle drain measure ditch that radius is 25mm.
Further, longitudinal ditch of receiving is the longitudinal receipts ditch of semicircle that radius is 25mm.
Further, longitudinal flat stone gutter is the longitudinal flat stone gutter of semicircle that radius is 50mm.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1, in the utility model, the percolating water ejectment structure of wall in tunnel is provided with longitudinal receipts water at the top of anticollision kerbstone
Ditch A3 is provided with drain measure ditch A4 in anticollision kerbstone outer surface, is provided on the flat stone of anticollision kerbstone bottom longitudinal flat
The percolating water of wall in tunnel can be collected and be discharged into the drainage system in tunnel by specific path by stone gutter A5, be prevented
It hits longitudinal ditch A3 that receives at the top of kerbstone and collects percolating water, longitudinal ditch A3 longitudinal slope of receiving is consistent with tunnel longitudinal slope, the leakage of collection
Water flows into the flat stone draining in the longitudinal direction adjacent with anticollision kerbstone bottom by the drain measure ditch A4 that anticollision kerbstone outer surface is reserved
In ditch A5, longitudinal flat stone gutter A5 longitudinal slope is consistent with tunnel longitudinal slope, and the percolating water in longitudinal flat stone gutter A5 is vertical with tunnel
Slope is discharged into the transversal ditch of tunnel minimum point or the inspection shaft of pre-buried transverse drain, and then is discharged into tunnel drainage system.It should
The percolating water ejectment structure design of wall is simple in tunnel, percolating water by effective Path-collection and can be discharged into the draining system in tunnel
In system, the application of Practical Project is strong.And the pre-buried a large amount of drainpipe ejectment percolating water under road surface is not needed, construction is more held
Easily, cost is more economical, and maintenance is more convenient.
