A pedestrian bridge and its construction method

Abstract

The invention discloses a pedestrian bridge. The pedestrian bridge comprises a bridge body, and further comprises a plurality of long-strip-shaped concrete foundation platforms which are arranged at intervals, wherein the upper surfaces of the plurality of the concrete foundation platforms together form a bearing plane, and an underground pipeline channel is formed between each two adjacent concrete foundation platforms. Furthermore, the pedestrian bridge comprises a plane steel frame arranged on the bearing plane and a support pillar arranged on the plane steel frame, wherein the bridge body is supported by the support pillar. The invention further discloses a construction method of the pedestrian bridge. According to the pedestrian bridge and the construction method thereof, the plurality of the long-strip-shaped concrete foundation platforms are used to replace traditional pile foundations to support the pedestrian bridge, and the depth and the area of a foundation pit are greatly decreased under the circumstance that the same support effects are obtained. Due to the fact that the depth and the area of the foundation pit are greatly decreased, a person does not need to protect peripheral building foundations or arrange pit wall supports in construction, and the construction is simple and convenient, a construction period is short, construction cost is low, and furthermore no influence can be caused to underground pipelines.

Description

technical field [0001] The invention relates to a bridge and a bridge construction method. Background technique [0002] In my country, urban pedestrian bridges mainly use deep pile foundations. As far as the current construction of urban pedestrian bridges is concerned, there are the following problems: [0003] 1. Regardless of the use of friction piles, end-bearing piles, prefabricated piles or bored piles, there are problems of large construction area and deep foundation pit depth. During construction, it is necessary to protect the foundation of the surrounding buildings and set up pit wall supports. At the same time, due to reasons such as geology or groundwater, the supporting area of ​​the pit wall is large, resulting in difficult construction, high construction cost and long construction period. [0004] 2. The large amount of excavation during construction will seriously affect the lives of surrounding residents due to the dust and mud generated. The long const...

AI Technical Summary

Problems solved by technology

[0003] 1. Regardless of the use of friction piles, end-bearing piles, prefabricated piles or bored piles, there are problems of large construction area and deep foundation pits. During construction, it is necessary to protect the surrounding building foundations and set up pit wall supports

At the same time, due to geological or groundwater and other reasons, the pit wall supports a large area, resulting in difficult construction, high construction costs and long construction period

[0004] 2. During the construction, the amount of excavation was large, and the dust and mud generated seriously affected the lives of the surrounding residents.

The long construction period will also lead to long traffic jams

[0005] 3. Due to the large depth of the foundation pit, it is easy to affect the urban underground pipelines and cables during the construction of the pile foundation
