Problems solved by technology

[0004] The technical problem to be solved by the present invention is: after canceling the red and green lights to direct traffic at the intersection, solve the problem of unimpeded passage of motor vehicles, pedestrians and non-motor vehicles in all directions at the same time
The roadway of the first-floor bridge in the air of the Changtong Bridge at the intersection of steel structure is mainly to solve the problem of motor vehicles turning left and rear, and the simultaneous driving of three-dimensional intersections going straight horizontally. problem going straight

example 1

[0026] Example 1. figure 1 For the plan view of the present invention, what numeral represents among the figure is: sidewalk (7), non-motor vehicle lane (8), isolation zone (9), motor vehicle driveway (10-123456 in the east, 123456 in the south, 123456 in the west , North 123456), the motor vehicle driveway (11) that turns left and the left rear steering as one, the bridge deck motor vehicle driveway (12) that goes straight horizontally, the overpass (13) that pedestrians and non-motor vehicles use. The specific routes for motor vehicles traveling in all directions at the same time on the unblocked bridge at the intersection are as follows:

[0027] Routes for motor vehicles traveling from south to west, north, east, and south:

[0028] Vehicles turning left from south to west: Turn left at 90 degrees from the upper bridge on the (South 4) carriageway and go straight to the lower bridge on the (West 3) carriageway.

[0029] Vehicles going straight from south to north: Just g...

example 2

[0047] Example 2. figure 2 What is shown is the air bridge pavement of a one-story steel structure crossing smooth bridge built on the basis of the road marking lines of motor vehicles in all directions on the existing crossing and crossing. carriageway. The air bridge roadway of the Changtong bridge at the intersection, the four bridge roadway for motor vehicles to turn left and left and rear as a whole, and the two air bridge roadway for motor vehicles to go straight horizontally are raised by 4.50 meters, so that motor vehicles The four traffic roads where the vehicle turns left and the left rear are integrated, and the two traffic lanes for motor vehicles to go straight horizontally, along the uphill ramp of the Changtong bridge at the intersection, and drive on the bridge pavement roadway with steel structure. As a result, vehicles driving on the Changtong bridge are left-turning, left-rear-turning and horizontal straight-going vehicles, and longitudinal straight-going ...

example 3

[0048] Example 3. image 3Described is, the bridge pavement driveway (11) of the unimpeded bridge at the crossroads of the intersection that the motor vehicle driving of 4.50 meters high above the ground distances the ground 4.50 meters from the left steering and the left rear steering, it is made of the uphill ramp of the steel structure, the uphill rear Keep left on the straight road (11---1), turn left to a 90-degree semi-circular curve (11---2), go straight and then lean on the downhill road to the right (11-3), continue to turn left A 90-degree circular closed shape bend (11---4) and a downhill slope (11-5) after going straight. The driving method of turning left is: go straight from the ground (4) driveway to the uphill ramp (11---1) of the Changtong bridge at the intersection, turn left through the semicircular-shaped driveway (11---2) 90 After 10 degrees, go straight in the direction, and then go downhill from the right straight road (11---3) into the ground straight ...

Abstract

The invention relates to a bridge deck device of a smooth-moving bridge for a steel-structure intersection, which is constructed above the intersection. In the device, a triangular single annular closed bridge deck traffic lane and a transverse straight going bridge deck traffic lane which enables left turning and left rear turning of motor vehicles into a whole can be manufactured by utilizing the relationships of upper and lower intersections, front and rear intersections and left and right intersections of an air bridge deck which is 4.50 meters high from the ground. Furthermore, a foundation combination using the two bridge decks forms the smooth-moving bridge for the intersection, and a method for planar crossing traffic of motor vehicles in crossroads is changed into a method for vertical crossing traffic so as to solve the running problem that motor vehicles cannot move smoothly in each direction of the intersection in each direction at the same time. Four steel structure passenger bridges or an x-shaped underground passage can be constructed to solve the problem that passengers and non-power-driven vehicles cannot walk or run smoothly in each direction.

Description

Technical field: [0001] The present invention relates to a method of constructing a one-story steel structure bridge pavement above the existing crossing area, utilizing the up and down crossing, front and rear crossing and left and right crossing relations of the air bridge pavement at a height of 4.50 meters from the ground , make motor vehicle left-turn and left-back turn and transverse straight bridge roadway, and the left-turn and left-back turn into a triangular single-circle closed bridge roadway and two transverse straight bridge roadway The driving road is the main device. In this way, the driving mode of motor vehicles at the crossroads is changed to the driving mode of three-dimensional intersections, and a steel-structured crossroad bridge is built to solve the problem of unimpeded driving of motor vehicles in all directions at the same time at the intersection. On the outside of the four directions of the Changtong Bridge at the intersection of the steel structur...
