The sidewalks on both sides are equipped with hanging plates on the outside, and the communication cables are embedded to cross the Luohe River.
At the same time, the western half starts the enclosure construction.
They are installed at the connection between pier and bridge, which can transfer the load of bridge to pier and play the role of buffer and isolation.
In May this year, the peony bridge ushered in the first comprehensive overhaul since its completion.
The surface is painted with dark gray frosted material, and the middle is decorated with Golden Peony.
On the morning of the 15th, the reporter saw on the peony bridge that the overhaul project of the east half of the bridge has entered the final stage, the newly laid bridge deck is flat and tidy, and the workers are installing machine and non isolation guardrails.
In addition, the isolation guardrail adopts the fixed installation method, and the anti-collision ground beam design is added to the municipal bridges in the city for the first time, which has higher safety performance and ensures safer passage of passing vehicles and pedestrians.
This coating can play a good role in waterproof and seepage prevention, and is convenient for cleaning.
Taking the opportunity of this overhaul, the Bureau comprehensively upgraded the bridge deck isolation guardrail, the new guardrail used solid materials, and two rows of upper and lower anti-collision beams were added on one side of the motorway.
● bridge bearings there are 3200 bridge bearings in Peony bridge.
At that time, peony bridge will provide greater convenience for citizens to travel in a healthier state.
The reporter learned from the municipal urban administration that from now on, the east half of the peony bridge is officially opened to traffic.
Due to long-term wind and rain erosion, the hanging plate made of concrete is damaged and aged, which affects the safety of pedestrians under the bridge.
Don’t underestimate these “parts”.
The surface stains can be removed by simple washing with water.
Different from the previous isolation guardrail, the appearance of the newly replaced isolation guardrail is more stable and atmospheric.
In addition to the replacement of machine and non isolation guardrails, there are many new changes in the east half of Daqiao.
Not only the shape is upgraded, but also the safety performance is greatly improved.
It has been 22 years since it was completed and opened to traffic.
There have been cracks and water seepage problems.
Generally speaking, the service life of bridge bearings is 15 years, and the original bearings of peony bridge have been used for 22 years, resulting in displacement and aging.
● the peony bridge with hanging plates on the outside of the sidewalk has a total length of 1369.65m.
During the overhaul, some hanging plates of the approach bridge were replaced with new steel plates, which have stronger corrosion resistance and longer service life.
According to the relevant person in charge of the municipal urban administration, the isolation guardrail previously used by the bridge was movable and easy to deform and shift after being hit by vehicles.
The reporter saw that the anti-collision ground beam is poured with concrete, 20 cm high, as the base of the isolation guardrail.

● the sidewalk of peony bridge is about 3M wide.
Peony bridge is the third municipal bridge across Luohe River in Luoyang.
Previously, it was laid with ordinary concrete and has been in service for 22 years.
During this overhaul, these piers were reinforced, and all piers were coated with fair faced concrete protective agent to enhance the durability of piers.
The whole reinforcement project involves 18 projects, including the demolition and reconstruction of the deck pavement of the main bridge, the upgrading and reconstruction of the deck drainage system and expansion joints, the jacking and replacement of bridge bearings, the replacement of machine non isolation guardrails, pier reinforcement, etc.
● the piers have been brushed with wind and water for a long time, so that some piers of the main bridge of Mudan bridge have different degrees of cracks and weathering.
At present, 3200 bearings of the whole bridge have been replaced.
The surface of the anti-collision ground beam is coated with fair faced concrete protective agent.
“The peony bridge reinforcement project has many construction procedures, scattered operation surfaces, and frequent precipitation since July this year, which has a great impact on the construction period.” the relevant person in charge of the Municipal Urban Administration said that at present, the bureau is accelerating the project according to the requirements of the working mechanism of “Road office” to ensure that the bridge is fully opened to traffic before February next year.
During the overhaul, the sidewalk was re paved with polyurethane anti-skid ceramic particles, which was not only beautiful and durable, but also anti-skid and anti-seepage.
