Embodiment 1

[0029] according to figure 1 As shown, the covering surface 1 is composed of a first covering surface 11, a second covering surface 12 and a third covering surface 13. When repairing the bridge deck of an interchange overpass, the first covering surface 11, the second covering surface 12 or the third covering surface 11, the second covering surface 12 or the third covering surface can be selected through the combination of repair areas. The covering surface 13 covers the bridge deck. Since the covering surface 1 is the first covering surface 11 , the second covering surface 12 and the third covering surface 13 , the transportation, repairing and splicing operations of the covering surface 1 are convenient.

[0030] Further, the noise reduction and water absorption device 3 includes a noise reduction water absorption plate 31 and a filling groove 32, and the noise reduction water absorption plate 31 and the filling groove 32 are provided in several groups and are arranged altern...

Embodiment 2

[0033] After the cladding 1 covers the bridge deck of the interchange overpass, the noise reduction water absorbing plate 31 is brought into contact with one side of the bridge deck, so that the noise reduction absorbing plate 31 performs the noise reduction operation of the cladding 1 and the bridge deck.

[0034] Further, the inside of the cladding 1 is provided with a pouring chamber 6, the pouring device 5 includes a first pouring steel bar 51, a steel bar 52 and a second pouring steel bar 53, and the pouring chamber 6 includes a first pouring The first pouring groove 61 of the pouring steel bar 51 is included. and the second pouring groove 62 for accommodating the second pouring steel bar 53 , the first pouring steel bar 51 is flush with the first pouring groove 61 and the second pouring steel bar 53 is flush with the second pouring groove 62 .

[0035] Further, the reinforcing bars 52 are arranged inside the first pouring groove 61, and the reinforcing bars 52 slightly pr...

Embodiment 3

[0039] After the cladding 1 is merged, concrete is added to the inside of the pouring chamber 6 through the second filling hole 43. During the merging of the cladding 1, due to the first pouring steel bar 51 and the first pouring groove 61, the second pouring steel bar 53 and the second pouring The groove 62 is flush, so after the cladding 1 is merged, the first pouring steel bar 51 is connected with the first pouring steel bar 51, and the second pouring steel bar 53 is connected with the second pouring steel bar 53, but the steel bar 52 slightly protrudes from the first pouring groove 61 and protrudes. The distance is 1cm, so the two steel bars 52 will be squeezed and deformed after contacting in the process of merging the cladding 1. After the concrete enters the pouring chamber 6, the extruded cladding 1 can be used to strengthen the pouring effect of the concrete, thereby improving the cladding 1. connection strength.

[0040] Further, the lifting device 2 includes a screw...

Abstract

The invention discloses an interchange structure for covering an existing road on a newly-built expressway, which comprises a covering surface, and the covering surface comprises a first covering surface, a second covering surface and a third covering surface; comprising a noise reduction and water absorption device which is arranged on one side of a covering face. Comprising covering surface connecting assemblies and a pouring device, and a first covering surface, a second covering surface and a third covering surface are fixedly connected through the covering surface connecting assemblies and the pouring device. According to the interchange structure for covering the existing road on the newly-built expressway, the covering surface is composed of the first covering surface, the second covering surface and the third covering surface, and when the bridge surface of an interchange overpass is repaired, the first covering surface, the second covering surface or the third covering surface can be selected through repairing area combination, so that the bridge surface is covered; due to the fact that the covering faces comprise the first covering face, the second covering face and the third covering face, the covering faces are convenient to transport, repair and splice.

Description

technical field [0001] The invention belongs to the field of interchange road construction, and in particular relates to an interchange structure with a newly built expressway overlying an existing road. Background technique [0002] The interchange structure refers to the interchangeable interchange, and the interchangeable interchange refers to a crossing method in which cross-line structures are set to separate the intersecting road space, and the upper and lower roads are connected by ramps for turning vehicles. Interchangeable interchanges vary according to the intersection and geometry of the traffic trajectories at the intersection. Interchangeable interchanges can be divided into general interchanges and hub interchanges. General interchangeable interchanges are mainly used for the intersection of arterial roads such as expressways and local roads, and mainly serve the access and distribution of local traffic flows. The hub-type interchange is mainly used for the i...
