On-bridge green belt construction process and bridge construction through process

Abstract

The invention discloses an on-bridge green belt construction process and a bridge construction through the process in the technical field of bridge greening. The process includes the following steps of S1, manufacturing groove beams, wherein U-shaped groove beams are prefabricated on site through concrete and steel strands; S2, hoisting the groove beams, wherein the U-shaped groove beams are hoisted to preserved positions on an on-bridge green belt; S3, laying pipelines, wherein water permeation and drainage pipes and mains supply pipelines are laid in the U-shaped groove beams; S4, wet connecting the ends, wherein concrete is poured in a seam between the ends of every two adjacent U-shaped groove beams for wet connecting; S5, backfilling planting layers, wherein the backfilling of the planting layers is conducted in the U-shaped groove beams, and the sinking type green belt is formed. The cross section of a bridge surface of the bridge constructed through the process and the cross section of roads at the two ends of the bridge are consistent in side, the slow car and fast car driving safety are effectively ensured, the landscape on the bridge is maintained, the pipelines in the green belt smoothly pass by the bridge, and meanwhile the cleaning workload of the bridge surface can be effectively reduced due to the sinking type structure of the green belt.

Description

technical field [0001] The invention relates to the technical field of bridge greening, in particular to a construction technology for a green belt on a bridge and a bridge constructed by the technology. Background technique [0002] At present, the structures along the road can be divided into three forms: road, bridge and tunnel, and the two ends of the bridge and tunnel are connected with the road. Limited by the construction cost, the width of most bridges is smaller than the width of the road. In order to keep the number of lanes on the bridge as consistent as possible with the number of lanes on the road, green belts are generally not set on the bridge, which causes vehicles to pass by on the road. The bridge needs to change lanes, which often leads to accidents. In order to ensure the safety of slow trains and express trains, it is urgent to make the cross-sectional size of the bridge deck (especially the size of the green partition belt on the bridge deck) consisten...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing green belts on the bridge are after the bridge is built, and some planting boxes with green plants are placed on the bridge deck. The way of fixing the planting box makes the municipal pipelines on both sides of the bridge only pass through the bridge deck, resulting in the exposure of each pipeline on the bridge deck, which is less safe

At the same time, the planting box further increases the bearing capacity of the bridge and shortens the service life of the bridge
