general situation
Shizilin Bridge is located on the Haihe River at the junction of Nankai District, Hongqiao District and Hebei District.
The original bridge was built in 1954, with a length of 93m and a width of 24.6m The main bridge is divided into three spans with a span of 24m+45m+24m. The structure is a prestressed concrete box continuous cantilever beam with variable cross-section.
1994 widened to 43m. A new bridge with a width of 9.3m and a structural section of three-span prestressed concrete box continuous beam with a span of 25.2m+45m+25.2m will be built on both sides of the old bridge. ..
In August 2003, in the comprehensive development and reconstruction of Haihe River, because the clearance of the old bridge could not meet the navigation requirements of Haihe River, Tianjin Urban Construction and Design Institute completed the overall jacking design of the bridge, and successfully applied the jacking translation technology to the bridge reconstruction field for the first time in China, achieving a major breakthrough in the domestic bridge reconstruction technology.
The project was implemented by Tianjin Urban Construction Group General Contracting Company, and the bridge body was successfully hoisted with computer control technology, and the hoisting height was 1.438+0 m.
design concept
The landscape design of the new bridge adopts the modern design concept, based on the principle of building a world-famous river and a scenic bridge, and on the basis of fully considering the harmony between the Haihe River and the surrounding landscape and buildings, the original four stone lions at the bridgehead are retained, and hundreds of new stone lions of different sizes are molded in different parts of the bridge railing, bridge body and pier.
In particular, the relief of the lion image is used at the pier, which means that when people sail through here, they can also see the lovely little lion passing under the bridge, which fully embodies the characteristics of the Lion Forest Bridge. Lions come in different shapes, each one is different, some growl, some bow their heads to rest, some are lively and lovely, and they have become a veritable lion forest.
In addition, the deck treatment of Shizilin Bridge will use colored asphalt for the first time, which is unique in lighting treatment and particularly spectacular at night. In order not to affect the overall landscape of Shizilin Bridge, the gas pipeline next to Shizilin Bridge was also changed to cross under the river.
It is unique in lighting treatment, and the night effect is particularly spectacular.
Uplift engineering
The lifting project of Shizilin Bridge is the first successful application of jack-up translation technology in the field of bridge reconstruction in China. It is a breakthrough in domestic bridge reconstruction technology and a precedent in the field of urban bridge design.
The hoisting of Shizilin Bridge is unprecedented in China, and it is the first hoisting project in China!
Less than 1 month, the old lion forest bridge, which weighs 4200 tons and has experienced 30 years of wind and rain, was pushed into place by the bridge. After the whole bridge is jack-up by computer control technology, temporary support is carried out first, and cast-in-place concrete filled steel tubular columns are used as permanent support. After reaching the design strength standard, the bearing was installed in place, and finally the overall "length and height" of the original bridge was realized. 48660.6886868866 1
The scenery on the bridge
There are 184 lions on the Lion Forest Bridge.
It turns out that there are three kinds of lions on the Shilin Bridge, one is two pairs of identical white marble carvings, the other is the high relief on the stone piles between the bridge railings, and the third is the cast iron lion on the railing post between each stone pile. There are 184 lions on the Lion Forest Bridge.
As the symbol of the Lion Forest Bridge, the four lions at the bridgehead were renovated, and 1 177 lions were added at different parts of the bridge, making the bridge a veritable "lion forest".
