Embodiment Construction

[0027] specific implementation plan

[0028] An improved full cloverleaf interchange can be used in the design of a full-interchange interchange at the intersection of two expressways; its fast straight lanes are divided into two layers, such as high-rise in the east-west direction, and low-level in the north-south direction, with the high-rise lanes in front of the intersection Start to drive up with a small slope at a certain distance, drive horizontally within the required range of the interchange, and keep the low-level lanes at the same height as the ground.

[0029] Such as figure 1 The improved full cloverleaf interchange has four left-turn ramps L (figure numbers: L1, L2, L3 and L4) to meet the left-turn driving of vehicles, such as figure 2 The left-turn ramp L is composed of a circular ramp and an extended ramp, wherein the circular ramp is composed of a circular front section a and a circular rear section b, and the extended ramp is composed of a straight section ...

Abstract

The invention relates to the field of overpass designing and discloses an invention scheme of an improved clover leaf overpass, thoroughly solving the problem of travelling crane weaving between confluence points of four left turn ramps of the clover leaf overpass and the travelling crane collision problem on a side road. The improved clover leaf overpass is characterized in that the tail end of each ring-shaped ramp of the traditional clover leaf overpass continuously extends to form a segment of extended ramp; the front segment of the extended ramp is parallel to a target main line, crossesupwards or traverses downwards to move away the main line; and the rear segment of the extended ramp bends outwards relative to the target main line, and crosses upwards or traverses downwards the other ring-shaped ramp and then is connected with a right turn ramp R with the same target main line. Through the guidance of the extended ramp, a left turn vehicle does not move to the main line at once after passing through the ring-shaped ramp, moves ahead along the direction of the target main line, bypasses a distance slantly outwards, crosses upwards and traverses downwards to move out from the target main line, and moves into the target main line through a right turn lane, thus avoiding the left turn vehicle firstly moving at right and the left turn vehicle secondly moving at right on thesame main line from weaving.

Description

technical field [0001] The invention relates to an overpass, in particular to an improved full cloverleaf overpass. Background technique [0002] Since the reform and opening up, with the rapid growth of my country's economy, the rapid increase of urban population has increased the number of vehicles; the construction of roads between cities and cities is also developing rapidly, more vehicles and road intersections cause vehicle congestion and congestion, many A large number of all-interchange overpasses have been built on the traffic arteries and expressways of large and medium-sized cities, and the conflicts of road plane crossing traffic flow are eliminated by means of space separation. [0003] The basic types of interchanges include cloverleaf, partial cloverleaf, trumpet, Y, ring and diamond, etc. Although different forms of interchanges can meet the full range of vehicles, they all have different forms of shortcomings. The main problems are: large area, many levels, ...
