Description
Technical field
The utility model belongs to municipal works city tunnel structure technique of design and construction field, and in particular to one kind is used for
The percolating water ejectment structure of tunnel sidewalls.
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, percolating water flows down meeting from side wall
It is directly discharged into maintaining roadway B1 by maintaining roadway B1 cover board hole, causes maintaining roadway internal water accumulation, no exclusion channel.The percolating water of side wall
It by effective Path-collection and cannot be discharged into the drainage system in tunnel, influence appearance quality inside and outside tunnel, driving may be brought to pacify
Full hidden danger, therefore, the percolating water timely and effectively excluded in tunnel is very necessary.
Utility model content
The purpose of this utility model is that: a kind of percolating water ejectment structure for tunnel sidewalls is provided, existing tunnel is solved
Road side wall percolating water cannot be by effective Path-collection and the problem of be discharged into the drainage system in tunnel.
The technical solution adopted in the utility model is as follows:
A kind of percolating water ejectment structure for tunnel sidewalls, the maintaining roadway including being set to side wall bottom, maintaining roadway are remote
It is additionally provided with gutter from side wall side, maintaining roadway bottom is provided with the plain coagulation with cross fall and slope aspect gutter
Soil, maintaining roadway are embedded with several consistent and slope aspects with the plain concrete cross fall of maintaining roadway bottom with gutter adjacent wall
The transverse drain of gutter.
Further, the minimum thickness of plain concrete is 100mm, and the cross fall of plain concrete is 2%.
Further, plain concrete is C15 plain concrete.
Further, 10m is divided between adjacent two transverse drains.
Further, the material of the transverse drain is PVC.
Further, the diameter of the transverse drain 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 tunnel sidewalls, in maintaining roadway bottom, backfill has cross fall
Plain concrete, with gutter bottom formed difference in height, maintaining roadway cover board hole collect percolating water, then by maintaining roadway and draining
The percolating water to deposit in maintaining roadway can be effectively discharged, by percolating water in the transverse drain being arranged on gutter adjacent wall
It has been directly discharged into tunnel drainage gutter, then has been discharged into the transversal ditch of tunnel minimum point or the inspection shaft of pre-buried transverse drain, into
And it is discharged into tunnel drainage system.The percolating water ejectment structure design of the tunnel sidewalls is simpler, can be by percolating water by effective
Path-collection is simultaneously discharged into the drainage system in tunnel, and the application of Practical Project is strong.And it constructs and is easier, cost is more economical,
Maintenance is more convenient.
