Abstract
The utility model relates to a water-drainage open cut tunnel aqueduct of a road cut section. In a high wind area, in order to reduce influence on line operation, a longer road cut is arranged at a local section, and waterflood on the earth surface of the road cut section cannot be dredged and drained and is easy to flood rails and trains. According to the utility model, an open cut tunnel along a road direction is arranged, and a curved wall of the open cut tunnel is of an inverted arch enclosed structure; the aqueduct which is vertical to the road direction is arranged above the open cut tunnel; wet masonry rubbles are refilled between the open cut tunnel and the aqueduct; the cross section of the aqueduct is trapezoid, and the aqueduct is composed of an aqueduct reinforced concrete baseplate and inclined aqueduct concrete side walls at two sides; and a deformation seam is arranged on the aqueduct at every interval of 10m. The water-drainage open cut tunnel aqueduct disclosed by the utility model downwards pass through a drainage structure in a form of an enclosed open cut tunnel, and the waterflood on the earth surface at the road cut section is effectively dredged and drained on the premise of furthest reducing the influences of the drainage structure and other facilities on line operation safety.
Description
Technical field
The utility model belongs to the traffic engineering technical field, is specifically related to a kind of dug way draining open cut tunnel aqueduct.
Background technology
Domestic Bai Lifeng district and the three Shi Lifeng districts in the Lan-xing Railway second two-wire Xinjiang, for reduce strong wind to the influence of circuit operation with consider the setting of anti-Wind Engineering as far as possible, local paragraph is provided with long cutting; But Bai Lifeng district, three Shi Lifeng districts are located in cross flow area, Gobi desert; Rainfall is little but rainfall is concentrated, intensity is big, adds vegetation sparse, very easily causes water damage; Face of land flood can't guide, floods easily and track and train.
Summary of the invention
The purpose of the utility model provide a kind of can be at the dug way draining open cut tunnel aqueduct of the guide face of land, the cutting location flood of draining difficulty.
The technical scheme that the utility model adopted is:
A kind of dug way draining open cut tunnel aqueduct is characterized in that:
Be provided with the open cut tunnel along road direction, its bent wall is the inverted arch enclosed construction;
The top of open cut tunnel is provided with the aqueduct vertical with road direction;
Be the backfill filler between open cut tunnel and the aqueduct.
The form of fracture of described aqueduct is trapezoidal, is made up of the aqueduct concrete side wall of aqueduct reinforced concrete floor and two tilt.
When the aqueduct below is backfill stone, is close to aqueduct reinforced concrete floor below aqueduct bed load cobble bed course is set.
Described aqueduct is every to be provided with the deformation joint vertical with the aqueduct direction at a distance from 10m.
Described aqueduct deformation joint aqueduct initiating terminal is provided with vertical skirt.
The outside both sides of described open cut tunnel respectively are provided with pre-buried gutter, and its trend is consistent with the open cut tunnel direction with the gradient.
Described backfill filler is two parts, and the aqueduct below is the mortar flag stone backfill for the part of open cut tunnel, and other parts are that common native stone rammer is filled out.
The utlity model has following advantage:
The utility model is crossed drainage structures with break-through under the open cut tunnel form of sealing---aqueduct, reducing to greatest extent under drainage structures and the prerequisite of other facilities the influence of circuit operation security, and the face of land flood to the cutting location carries out guide effectively; Mortar flag stone is adopted in the open cut tunnel backfill of aqueduct scope, and along the aqueduct direction aqueduct deformation joint is set, and can prevent effectively that differential settlement from causing the aqueduct cracking.
Description of drawings
Fig. 1 is the aqueduct layout plan.
Fig. 2 is the aqueduct longitudinal section.
Fig. 3 is aqueduct open cut tunnel section cross section.
Fig. 4 is the general section of aqueduct cross section.
Among the figure, 1-open cut tunnel, 2-aqueduct, 3-upper reaches parallel works; 4-downstream parallel works, 5-aqueduct deformation joint, the 6-aqueduct skirt that hangs down, the backfill of 7-mortar flag stone; The common native stone of 8-rams fills out the pre-buried gutter of 9-, 10-aqueduct bed load cobble bed course; 11-aqueduct reinforced concrete floor, 12-aqueduct concrete side wall, 13-orbital plane.
The specific embodiment
Below in conjunction with the specific embodiment the utility model is carried out detailed explanation.
A kind of dug way draining open cut tunnel aqueduct that the utility model is related; Be provided with open cut tunnel 1 along road direction; Its bent wall is the inverted arch enclosed construction; Adopt cast-in-place reinforced concrete structure, open cut tunnel 1 length confirms that according to cheuch orographic condition and aqueduct width open cut tunnel 1 provides the running environment of sealing for the train of dug way form.The top of open cut tunnel 1 is provided with the aqueduct 2 vertical with road direction.Be the backfill filler between open cut tunnel 1 and the aqueduct 2, the backfill filler is two parts, and aqueduct 2 belows are that open cut tunnel 1 adopts mortar flag stone backfill 7, and other parts are that common native stone rammer fills out 8.During being provided with of mortar flag stone backfill 7 in order to prevent that differential settlement from causing the aqueduct cracking.The form of fracture of aqueduct 2 is trapezoidal, and its sectional dimension is calculated definite according to the shape and the factors such as surface roughness coefficient, longitudinal gradient of the flow that passes through, aqueduct through waterpower.Aqueduct 2 is made up of the aqueduct concrete side wall 12 of aqueduct reinforced concrete floor 11 and two tilt, when aqueduct 2 belows are backfill stone, are close to aqueduct reinforced concrete floor 11 belows aqueduct bed load cobble bed course 10 is set.Aqueduct 2 is established deformation joint 5, is spaced apart 10m.For preventing the surface water scour, the skirt 6 that hangs down is set at deformation joint aqueduct initiating terminal.Open cut tunnel 1 outside both sides respectively are provided with pre-buried gutter 9, and its trend is consistent with open cut tunnel 1 direction with the gradient.The upstream and downstream of aqueduct 2 is answered corresponding setting upper reaches parallel works 3 and downstream parallel works 4.This open cut tunnel aqueduct structure also can be used for other graded crossing engineerings on road interchange etc. and last cross-line road.
