In figure: 1, face, riverbed or sea bed face; 2, land-based area road; 3, immersed tube tunnel; 4, trough.
Detailed description of the invention
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but can not be used for limiting scope of the present utility model.
In description of the present utility model, it should be noted that, term " longitudinal direction ", " transverse direction ", " on ", D score, "left", "right", " end ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
The immersed tube tunnel 3 of the present embodiment, comprises the end tube coupling that is connected with land-based area road 2 and at the middle tube coupling described in both sides between the tube coupling of end.Because end tube coupling needs to be connected with land-based area road 2, obviously it highly can higher than the height of middle tube coupling.In view of traditional immersed tube tunnel 3, from the end tube coupling of both sides, the degree of depth of more past centre then immersed tube tube coupling is darker, causes the operation of tunnel under deep water too many and foundation trench open excavation amount is too large.In the present embodiment, one or more slightly large counter-slope is arranged to the connection of middle pipeline section, thus form the tunnel structure of a vertical face shape entirety in wave segment type, and tunnel at least comprises two troughs 4.Wherein it is emphasized that, in " vertical face shape entirety is in wave segment type ", the line style of each trough 4 both sides of immersed tube tunnel 3 is the vertical circular curve of different radii, also namely the essence of immersed tube tunnel 3 shape is a curved section, and final integral tendency is the same with wave line segment.When the diameter of the circular curve of trough 4 both sides is tending towards infinity, then now immersed tube tunnel 3 shape essence is the straight line that multistage connects successively.
During concrete enforcement, when waters, place, tunnel has flood control to require, the two ends land-based area distance in tunnel can not be too near, can not take water channel, have ready conditions and make W type or other wave segment types when therefore tunnel is longer; In addition, when the waters passed through when tunnel needs to consider large ship navigation draft, except navigation channel place is deep-cut, other region can be lifted above, thus W type described in being formed or other wave segment type sections.Finally, when sea bed face is more smooth, for ensureing that the buried depth thickness vertical alignment in tunnel complies with sea or face, riverbed generally, the setting of thin portion can be carried out by W type or other wave segment types with this understanding.
The immersed tube tunnel 3 of the wave segment type of the present embodiment, reduces the degree of depth of foundation for laid pipe, thus reduces installation difficulty and the construction risk of tube coupling; Decrease immersed tube foundation trench open excavation amount simultaneously, protect water environment.When being especially applicable to the larger submerged tunnel of span, this kind of vertical face design of shape entirety in wave line segment embodies its advantage more.
Should be understood that, in the description of the present embodiment, have ignored the shape of cross section of immersed tube tunnel 3, only each immersed tube tube coupling is approximated to the linear structure along length of tunnel direction.
When the quantity of the trough 4 of immersed tube tunnel 3 is two, now the vertical face shape of immersed tube tunnel 3 is class W shape, refers to Fig. 1.The end tube coupling at its middle left and right two ends connects land-based area road 2 respectively, then arranges tunnel overall structure according to the condition of face, riverbed or sea bed face 1 and land-based area road 2.Wherein, can environmentally need to arrange change slope, many places on " the wave line segment " of the immersed tube tunnel 3 of shape entirety in vertical face in " wave segment type ", final formed reasonable, a linear smoothness of buried depth, draining efficiently easily face of indulging, tunnel arrange.
It is worth mentioning that, be for the tunnel of V-arrangement relative to traditional vertical face shape, because v-shaped structure only has a low spot being easy to conflux, therefore generally can only arrange pump house and/or a collecting-tank under water; And vertical face shape is the tunnel of U-shaped, owing to not having the low spot being easy to conflux, therefore general inconvenience arranges pump house and/or collecting-tank under water.And in the present embodiment, immersed tube tunnel 3 comprises multiple trough 4 position, and all trough 4 positions all can arrange concentrated pump house under water and/or collecting-tank with suiting measures to local conditions, thus provide condition for the draining of the larger tunnel longitudinal direction of length is smooth and easy, and the waste water such as the cleaning of more effectively collecting in tunnel and fire-fighting.In addition, make trough 4 be uniformly distributed along immersed tube tunnel 3 length direction as far as possible, thus more reasonably improve the drainability of immersed tube tunnel 3, shorten the distance outside waste water discharge hole, the emergent drainability under raising bad condition in tunnel.
Above embodiment only for illustration of the utility model, but not to restriction of the present utility model.Although be described in detail the utility model with reference to embodiment, those of ordinary skill in the art is to be understood that, various combination, amendment or equivalent replacement are carried out to the technical solution of the utility model, do not depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model.
