Embodiment Construction
[0049] Various embodiments of the invention will be described in more detail below with reference to the accompanying drawings. In the various drawings, the same elements are denoted by the same or similar reference numerals. For the sake of clarity, various parts in the drawings have not been drawn to scale.
[0050] Such as Figure 1 to Figure 5 As shown, the present invention provides a construction method for the flyover 400 at the intersection of the main line road and the local road. The construction method for the flyover 400 at the intersection of the main line road and the local road includes the following steps 1 to 6.
[0051] Step 1: Temporarily divert the local road at the construction position of the overpass 400 of the local road to form a temporary local road 100 in an unopened state;
[0052] In this step, in order to follow up the construction of the overpass 400, it is necessary to temporarily reroute the road at the construction position of the overpass 4...

A method for constructing an overpass at the intersection of a main line road and a local road is disclosed, comprising: Step 1: temporarily diverting the local road at the construction position of the overpass on the local road to form a temporary local road in an unopened state; Step 2: Build a temporary bridge on the temporary local road, which is located at the intersection of the unopened temporary local road and the construction road; Step 3: After the temporary bridge is built, open the temporary local road, and switch the passage of people and vehicles from the construction position of the bridge On the temporary local road; step 4: excavate the construction access road below the access bridge, and get through the construction access road; step 5: build an overpass at the construction position of the overpass, so that the local road passes under the overpass; step Six: After the overpass is put into use, clear the temporary local roads. The method can make the traffic smooth, and the traffic does not need to be cut off during the whole construction process; it is safe and stable, economical and environmentally friendly, and easy to dismantle.
Description
technical field [0001] The invention relates to the technical field of road construction, in particular to a method for constructing an overpass at the intersection of a main line road and a local road. Background technique [0002] During the construction process of highway and railway projects, the main road crosses the local road from time to time. When the elevation of the local road is lower than the main road, it is necessary to build a channel culvert first to ensure the smooth traffic and the passage of people on the local road, and then carry out subgrade filling. , and when the elevation of the local road is higher than the main line, it is necessary to set up an overpass for the passage of vehicles and personnel, and the temporary relocation and diversion of the local road will inevitably be involved in the construction of the overpass, otherwise the traffic can only be cut off according to the traditional method, which is of great importance to the world It is al...
