Embodiment 1

[0024] Design

[0025] Taking the diameter of the concrete column in the core pressure area of ​​the bridge pier column 10 as 2.75 m and the thickness of the concrete protective layer as 5 cm as an example, the bridge pier column diversion device in this implementation is designed and installed. From figure 1 It can be seen that the relative position relationship between the bridge pier column 10 and the deflector of the device, the first arc segment 1, the second arc segment 5 and the third arc segment 3 of the deflector of the device have a diameter of 2.8 m arc shape, the first arc segment 1 selects a cyclotron (radial spiral shape) as the flat line model of the easement curve. The radius of curvature along the curve changes continuously from -1 / 2.8 to +1 / 2. First arc segment 1 and first curve segment 2, first curve segment 2 and third arc segment 3, third arc segment 3 and second curve segment 4, second curve segment 4 and second arc segment 5 are smoothly connected, and th...

Abstract

The invention discloses a bridge pier stud flow guide device. The bridge pier stud flow guide device is composed of two flow guide plates which are fixedly connected in a welding mode or through bolts. The two flow guide plates are symmetric about the connection surface. The water erosion and corrosion resistance capacity of an existing bridge pier stud is improved by additionally installing the bridge pier stud flow guide device on the outer side of the existing bridge pier stud. The bridge pier stud flow guide device is simple in design and convenient to install. The service life of bridge pier studs can be prolonged effectively.

Description

Technical field [0001] The field of bridge construction of the present invention specifically relates to a bridge pier column diversion device. Background technique [0002] At the beginning of reform and opening up, my country's highway mileage was only 888,000 kilometers, and there were only 128,000 highway bridges with a total length of 3,283 kilometers. After 30 years of hard work, by the end of 2007, the total mileage of my country's highway network reached 3.58 million kilometers. There are a total of 570,000 highway bridges, 23,200 kilometers long, an annual increase of 15,000, and 664 kilometers long. The development of highway bridge technology has achieved world-renowned achievements. In the following seven years, Chinese bridge engineers made independent innovations and completed batches of world-class difficult bridge construction projects, pushing my country from a big bridge country to a bridge power. With the groundbreaking of world-class super projects such as t...
