Description

The invention relates to road construction and can be used in the construction or reconstruction of intersections at different levels of highways, mainly in urban conditions.

Known transport interchange, containing the intersection at different levels of two roads, containing two right-hand exit, left-turn exit, left-turn loop exit, zone of the abutment-junction of the highway (1). The denouement is not compact, it does not allow the use of the territory above the denouement to accommodate industrial facilities, etc.

The technical result of the invention consists in the possibility of reducing the area for traffic intersection, as well as improving the redistribution of traffic flows, eliminating traffic congestion, increasing throughput while ensuring traffic safety.

The technical result is achieved by the fact that the traffic intersection, comprising the intersection at different levels of two roads, two right-handed exits, one left-handed exit, two left-hinged looped exits, an open-junction zone of the highway, also contains a loopway made at the upper level, and a left-hinged loopway exit having a common section, two left-hinge loop-in entrances, four turns, and the loop overhang is expressed by the relation L≥Н · 2ctg α + l, where L is the loop overhang, H is the distance between the surfaces intersecting to og, m, l is the horizontal section of the road between the exit and the entrance, l = 1 ÷ 450 m, and α is the angle of inclination of the exit or entrance in degrees, while buildings of objects of trade and consumer services are located above the lower level road, limited by loopback passage and industrial facilities.

Figure 1 shows the transport interchange with a loopway in the upper level, containing the intersection at different levels of two roads: lower level roads - 1 and upper level roads - 2.

Figure 2 - loopback passage, exit and entry, side view.

The road junction with a loopway in the upper level contains the intersection at different levels of two roads: lower level 1 roads with straight through passage in both directions and upper level 2 roads with a straight through section in one direction. The traffic intersection contains the zones of abutment-abutment.

From the lower level road 1, we will make a right-turn entrance to road 2 along arrow 3 and a left-hand loopback entrance to road 2 along arrows 4 and 5, as well as a turn along arrows 6 and 7.

From the lower level road 1, we will make a right-handed entrance to road 2 along arrow 8 and a left-hinged loopback entrance to road 2 along arrows 9 and 10, as well as a turn along arrows 11 and 12.

From the upper level road 2, we will loop through the upper level along arrows 13, 14, 15 and 16 and take the right turn onto road 1 along arrows 17 and 18, as well as the left-turn loop exit along arrows 13, 14, 19, 20 and 21.

From the top level road 2, we will make a right turn onto road 1 along arrows 22 and 12, a left turn onto road 1 along arrows 23 and 18, as well as turns 24 and 25.

The road junction contains the intersection at different levels of two roads: lower level 1 roads with straight through in both directions and upper level 2 roads with one straight direct. The traffic intersection contains a loop, the flight of which is expressed by the ratio L≥N · 2ctg α + l.

The movement of traffic flows in figure 1 is carried out according to the schemes below.

When driving on road 1 from right to left:

right-turn entry: 1-3-2, left-hand loopback entry: 1-4-5-2, U-turn: 1-6-7-1;

When driving on road 1 from left to right:

Right-turn entry: 1-8-2, Left-right entry: 1-9-10-2, U-turn: 1-11-12-1.

The traffic intersection contains the intersection at different levels of two roads, and the following options are possible: the lower level 1 road is located at level zero or below it in the tunnel, and the upper level 2 road is located at the overpass or level zero.

The lower level road can be blocked and on it limited by loopback passage, premises for objects of trade, consumer services and industrial and industrial facilities can be placed.

According to claim 2, the technical result is achieved by the fact that a traffic intersection containing an intersection at different levels of two highways, having two right-handed exits, a left-handed exit, a left-hinged loop exit, a zone of an abutment-adjoining road, also contains a loop passage made in the lower level, with a section common with a left-hinged looped exit, one left-handed congress and a looped right-handed exit, having sections in common with left-handed congresses, and the departure of the looped passage is expressed by the ratio L≥Н · ctg α + l, where L is the loopback departure, N is the distance between the surfaces of intersecting roads, m, l is the horizontal section of the road adjacent to the ramp, 1 = 1.0 ÷ 500 m, and α is the angle of inclination of the exit or entrance, degrees, while under the road the upper level, limited by loopback passage, can be located the premises of trade, consumer services and industrial facilities, while, as in claim 1, with an increase in the value of 1, the usable area also increases.

Figure 3 presents a traffic intersection with a loopback passage in the lower level, containing the intersection at different levels of two roads: upper level roads - 1 and lower level roads - 2. (Option 1).

In Fig. 4, there is a traffic intersection with a loopback passage at the lower level, containing the intersection at different levels of two roads: upper level roads - 1 and lower level roads - 2. (Option 2).

Figure 5 - loop passage, exit and entry, side view.

From the upper level road 1 (see Fig. 3), the right exit leaves, marked by arrow 3 to turn right along arrow 4 to road 2, and to the left - along arrows 5, 6 and 7 to road 2. Turn around arrows 6 and 8 to road 1. From the top level road 1, we will also make a left-hand loop exit to road 2 along arrows 9, 10 and 11. From the top-level road (see figure 4), we will also make a left-turn loop exit to road 2 along arrows 9 and 10.

From the top-level road 1, the right-hand exit leaves off at arrow 12 to road 2, as well as the left-hand loop exit at arrows 13, 14, 15 and 16 onto road 2. On the top-level road 1, we turn around at arrows 13, 14, 17 and 18.

Lower level 2 road has a loop passage under road 1 on arrows 19, 20, 15 and 16. Lower level 2 road has a right turn on road 1 on arrows 21 and 8. Lower level 2 road has a right turn on road 1 on arrows 22 and 23, as well as turns on arrows 24 and 25.
