Description

A kind of novel gradient slope culvert outfall drain structure
Technical field
The utility model relates to highway bridge and culvert engineering, specifically a kind of novel gradient slope culvert outfall drain structure.
Background technique
The outlet of mountain highway discharge culvert is usually located at the upper zone of side slope, and the water flow being discharged is flowed into along side slope Bottom of slope.However when encountering side slope and more rising steeply, the water flow dynamic energy along hillslope overland flow is larger, and easy side slope causes defective punching Brush, especially in mountain highway with a varied topography, horizontal alignment bend is more, and bottom of trench longitudinal slope is larger, and geological structure is changeable, causes Slope concentration is larger, and then side slope produces bigger effect.If slope surface is loess, due to the structural and under-compacted of loess Property, under the comprehensive function of rainwater and additional stress, collapsibility is shown as, and be frequently accompanied by generation loess settlement cave, loessial gulch, Phenomena such as Loess landslide, causes slope instability;If the slope surface rock of side slope is exposed, the water confluence that culvert is discharged is fast, infiltrates less, Kinetic energy is larger with flow velocity, be easy to form vortex, drop and hydraulic jump in slope foot, seriously destroy slope foot, if things go on like this side slope Stability constitutes threat.Therefore, it is easy to solve the discharge structure of existing gradient slope culvert so that side slope is seriously washed away, The problem of eventually leading to slope instability, it is very necessary for designing a kind of discharge structure suitable for gradient slope.
Summary of the invention
The utility model is easy to solve the discharge structure of existing gradient slope culvert so that side slope is seriously washed away, finally The problem of leading to slope instability, provides a kind of novel gradient slope culvert outfall drain structure.
The utility model adopts the following technical scheme that realization:
A kind of novel gradient slope culvert outfall drain structure, including culvert outlet, starting discharge structure, intermediate draining knot Structure and stilling pond;Originating discharge structure includes starting plunge pool and starting rhone;The starting plunge pool is set in side slope And be connected with culvert outlet, the left side wall for originating plunge pool is equipped with starting draining hole;It originates rhone and is laterally arranged along side slope, And the upper end is connected with starting draining hole;Intermediate discharge structure includes intermediate plunge pool and intermediate rhone;Fall the centre Pond is horizontally set at the lower section of starting plunge pool along side slope;The right side wall of intermediate plunge pool is equipped with centre and enters water hole mouthful, institute State it is intermediate enter water hole mouthful be connected with the lower end for originating rhone;The left side wall of intermediate plunge pool is equipped with intermediate scupper mouth;In Between rhone along side slope laterally be arranged, and the upper end with centre scupper mouth be connected;Stilling pond with baffle wall style is along side slope cross To the lower section for being set to intermediate plunge pool, the stilling pond is connected with the lower end of intermediate rhone.
It is discharged when water flow is exported from culvert, into starting plunge pool, is introduced into centre under the action of originating rhone Plunge pool, the water flow into intermediate plunge pool are introduced into stilling pond under the action of intermediate rhone.
Multiple intermediate discharge structures are provided between starting discharge structure and the stilling pond;Multiple intermediate discharge structure edges Side slope is laterally sequentially connected.
Bellows is equipped in the starting rhone and intermediate rhone.
The starting discharge structure and intermediate discharge structure are embedded in the inside of side slope.
The utility model is designed reasonably, the kinetic energy of water flow quilt when flowing through starting plunge pool, intermediate plunge pool and stilling pond Cut down step by step, avoid side slope and washed away by flowing water, maintain the stabilization of side slope, protect slope foot, efficiently solves existing steep The discharge structure of side slope culvert is easy so that the problem of side slope is seriously washed away, eventually leads to slope instability, is suitable for highway bridge Contain engineering, especially suitable for having the highway compared with gradient slope.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the floor map of the utility model.
In figure: the outlet of 1- culvert, 21- originate plunge pool, and 22- originates rhone, plunge pool among 31-, the draining of the centre 32- Slot, 4- stilling pond, 41- baffle wall style, 5- side slope.
Specific embodiment
It is described with reference to the accompanying drawings:
