SU958571A1 - Multilevel highway crossing - Google Patents

Description

- The invention relates to road construction and can be used in the construction of an intersection junction at different levels of highways, mainly in urban conditions. The intersection of roads located at different levels is known, including nine overpasses, nine four stops, four loopback areas with a bypass of the right intersection center connected to intersecting roads l. In this road crossing scheme (the so-called turbine type), there are 9 bridges, which requires a considerable area, increasing earthworks. access roads to intersecting roads, four roundabouts, and an overpass located in the center of the intersection on one of the FSJ roads. However, this intersection has insufficient throughput. The purpose of the invention is to increase the capacity of the intersection. The goal is achieved by the fact that the intersection of roads located at different levels, including access roads to intersecting highways, four ring exits from them and an overpass located in the center of the intersection on one of the roads, is equipped with three additional overpasses, each of which is located corresponding roundabout congress, and four additional, adjacent to intersecting highway roads, left turnaround congresses, two of which pass each under COOT, -I with an additional overpass and two They are under the third additional overpass. The drawing shows the proposed intersection, the plan. Intersecting roads 1 and 2 are interconnected by four left-turning loops 3-6, four left-turning semi-loops 7-10, respectively, and each other by congresses 11-14. 1 passes at an elevated level above the road 2 through the overpass 15.

Loop section 4 is made without overpass,., And with a uniform longitudinal slope as it enters the overpass 15.

The left turn loop sections 3/5 and 6 have one overpass 5, respectively 16, 17 and 18, located on the left turn back loop sites located at the maximum distance from the central overpass 15, i.e. from the intersection of 10 motorways 1 and 2.

A part of overpasses of left-turn loopback sections 3, 5 and b located between overpasses 15, 1b, 15, 17 and 18, 15, respectively, are at an elevated level parallel to the ground, as well as road 1 in the overpass 15, another part of overpasses , left-turning loop areas 3 and 5, located “. between overpasses 15, 16;, 157 17 along the route of transport to the entrance under overpass 15, passes with an equal longitudinal slope. A part of the overpass of the left-turn loop loop section b, located in the conduits 18, 15 along the path of transport from under the overpass. .15 10 points G, entering the overpass 18, runs with a uniform longitudinal slope. .thirty

Under the overpass 16, which is located on the left turning loop section 3, there pass two dollars, 7 and 8.

. Under the overpasses 17 and 18, which are located on the left turn loop sections 5, 6, there are half-loop sections 9 and 10..40, respectively.

Road 2, exits 11-14, half-loop sections 8 and 9 are at the level of the ground surface, - as well as part, half-loop section 7 behind the overpass 16, overpasses 19, 20 and part 45

half loop section 10 to half line 18 is also at ground level.

Part of the half-loop section 7, located at the intersection of overpasses 1 16, runs with a uniform longitudinal incline after the exit with overpasses 16 before the entrance under the overpass 15.

Part of the half-loop section 10, located at the intersection by overpasses 18 and 15, runs with a uniform longitudinal slope after the exit-from under the overpass 15 before starting to enter the overpass 18.

This type of junction at 2 levels serves for the movement of any type of transport.

Forg / 1ula Invention The intersection of roads located at different levels, including access roads to intersecting highways, four ring exits and an overpass located in the center of the intersection on one of the roads that, in order to increase the intersection capacity, it is equipped with three additional overpasses, each of which is located at the corresponding ring congress, and four additional motorways adjoining the intersection of the Cims, left-winged gate congresses, two. each of which passes under the respective additional overpass, and the other two, under the third additional overpass. . .
