Abstract
The utility model relates to a kind of efficient wave absorption structures applied in navigable tunnel, belong to hydraulic engineering navigation field.The utility model advantage is: 1, making full use of space where the pavement of two sides inside navigable tunnel, do not increase place space additionally；2, ship wave in navigable tunnel, fill the classification dispersion energy dissipating of sluicing long wave wave energy, improve wave absorption efficiency.
Description
Technical field
The utility model relates to a kind of efficient wave absorption structures applied in navigable tunnel, belong to hydraulic engineering navigation neck
Domain.
Background technique
China, river, central and west regions is predominantly located at mountain area, and the height of water is big, and beach is more, slope is steep, stream is anxious, multiple in high mountain gorge
Navigation structure is built under the conditions of miscellaneous has great difficulty and challenge.Navigable tunnel can make full use of site contour to be designed
And arrangement, it is adaptable, it is an effective way of solution high-mountain gorge areas navigation structure arrangement difficulty, however tunnel of opening the navigation or air flight
Hole is typical shallow water stenotic type navigation channel, and ship navigates by water in such navigation channel, and ship resistance increases, and speed reduces, and trim increases,
Steerage is deteriorated, and maneuvering performance reduces, and the possible asymmetric waters in ship two sides and ship wave, fill sluicing oscillation wave reflection it is folded
Add, asymmetric lateral force will be generated to hull, increases control course difficulty；In addition, navigable tunnel construction technique difficulty is high, ruler
Degree influences project cost greatly, according to the applicant understood, to be designed and arranged navigable tunnel sectional form that there is presently no phases
Codes and standards are closed, how reasonable wave absorption measure arrangement is carried out under the premise of not increasing its section scale as far as possible and construction is
One of the difficult point of navigable tunnel design.
Wave absorption (wave) the measure spininess usually said is to harbour seashore, wave flume etc., in bank slope (or physical model) two
End arrangement stake formula, box wave trap, and then rarely have research in this special restricted waterway in navigable tunnel, main cause
There is two: 1, navigable tunnel to be related to numerous influence factors such as geology, ship, navigation channel arrangement, the multidisciplinary friendship such as structural mechanics, hydraulics
Fork, construction difficulty are larger；2, the current construction of navigable tunnel both at home and abroad is substantially at starting state, relevant Construction and operation experience pole
It is deficient.Wujiang Goupitan navigable tunnel is first, China navigable tunnel put into operation, has just completed main body at present and has poured；It moves
The Stad tunnel (Stad Ship Tunnel) of prestige West Coast is planning demonstration.
Navigable tunnel belongs to typical shallow water restricted waterway, and no matter section scale is from structural stability, economical rationality
Property for can not it is larger, additionally due to direction of ship travel is consistent with the long wave direction of motion in tunnel channel, this leads to nothing
Method lays the conventional wave absorption measure of a wide range of complexity on long wave motion vertical face, otherwise will affect ship and passes through, while ship
The water body that any position navigation can disturb in middle channel in middle channel generates new wave source, this is designed for navigable tunnel
Propose great challenge.
Utility model content
For deficiency existing for present technology, the utility model is in order to solve the shipping agency of ship in navigable tunnel when driving
The problems such as wave action, and then a kind of efficient wave absorption structure applied in navigable tunnel is provided, with low cost, wave absorption efficiency
The features such as higher, convenient for installation and maintenance.
The technical solution adopted in the utility model is:
A kind of efficient wave absorption structure applied in navigable tunnel, comprising: bearing column, wave absorption transverse slat；Above-mentioned wave absorption
Transverse slat includes: the rectangle PVC board of two pieces of thickness 1cm；Two pieces of above-mentioned PVC boards etc. are big, and shape is identical, are highly not less than 60cm,
Width and bearing column are with tunnel side wall apart from identical；Two PVC transverse slat spacing 5cm, using the steel seat supports of 5cm in two PVC boards
Between；It is evenly arranged the circular hole of diameter 5cm in two PVC boards, is 15cm per horizontally-arranged, the adjacent 2 circular hole circle center distances of vertical setting of types；It is above-mentioned
Bearing column, that is, tunnel in the column on pavement is supported under the pavement of two sides；Above-mentioned wave absorption transverse slat be fixed on bearing column and
Between tunnel abutment wall.
Wave absorption transverse slat horizontal center line Installation Elevation is navigable tunnel design water level.
Above-mentioned wave absorption structure is no more than 20m along tunnel direction largest interval.
Specifically, the benefit of the utility model is as follows:
1, the utility model makes full use of space where the pavement of two sides inside navigable tunnel, does not increase field additionally
Ground space.
2, ship wave in navigable tunnel, fill the classification dispersion energy dissipating of sluicing long wave wave energy, improve wave absorption efficiency.
3, wave absorption platen size appropriate can be selected during practice of construction according to concrete engineering, general reference property is high.
Detailed description of the invention
Fig. 1 is mounted with the navigable tunnel diagrammatic cross-section of the utility model；
The enlarged diagram of the position Fig. 2 Fig. 1 M；
The diagrammatic cross-section in another direction of Fig. 3 the utility model wave absorption transverse slat.
Specific embodiment
The utility model is further described with reference to the accompanying drawing, following embodiment is only used for clearly illustrating this
The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
Embodiment one
Certain its sectional form of long range navigable tunnel is gateway opening type, and it is wide to design ship type by tunnel channel clear span 18m
10.8m designs maximum speed 3.0m/s, and respectively there are the pavements 1m wide 2 more than design water level for two sides.
Pavement 2 is lower to be arranged bearing column 3, wave absorption transverse slat 4；Wave absorption transverse slat includes: the rectangle PVC board of two pieces of thickness 1cm
41；Above-mentioned two pieces of PVC boards 41 are equal big, and shape is identical, height 60cm, and width and bearing column 3 are with tunnel side wall 1 apart from identical
For 55cm；Two PVC boards, 41 spacing 5cm, is supported between two PVC boards 41 using the steel seat 42 of 5cm；Uniform cloth in two PVC boards 41
The circular hole of diameter 5cm is set, is 15cm per horizontally-arranged, the adjacent 2 circular hole circle center distances of vertical setting of types；Above-mentioned bearing column 3 is in tunnel
The column on the lower support pavement in two sides pavement 2；Above-mentioned wave absorption transverse slat 4 is fixed between bearing column 3 and tunnel abutment wall 1.
4 horizontal center line Installation Elevation of wave absorption transverse slat is navigable tunnel design water level.
Wave absorption structure is along tunnel direction interval 15m.
