In these modern cities, there are so many kinds of bridges, like: stone arch bridges, highway bridges, railway bridges, tower bridges… Some of them are enough bigger that can cross the sea, and some of them are in the village just to connect the sides of a small river. Whatever they exist around our life all the time, all the time. Without any questions, they play a very important role that connect one place to another place and also offer a convenient way for people or we can say for the whole transportation system.
As a bridge, it has many methods to create its value, for example: except for connection, it also can be a feature spot. Try to think: Around our life, a majority of people would be restless when they drive a car on the way to work or home in a rush time. Can you imagine there has a bridge that full of creativity in front of your eyes? In this way, when people cross the bridge, they can have a taste of the fantastic view, actually should pay some tips, and as time goes by, there will have a win-win situation.
Statement of Problem
(1) We should consider about the materials.
(2) The view how to make a special bridge to attract people eyes.
(3) The scale of each part of the bridge is a little confused us.
First, it cannot fall down.
Second, the hight must not be shorter than 40cm.
Third, plan dimension must not be smaller than 100×30cm
Fourth, electrical writing installed with at least 10LED bulbs.
It should be strong, durable and finished to a high standard.
It must be possible to manufacture the design in the classroom.
It must be strong materials like wood.
We can use steel reinforced concrete to make the main body. The two bases of start and the end should be built under the ground, for the bases in the middle should be built in the water. Cause it should bear the wight of so many cars at the same time.
For example a beam bridge is utilised for short spans and through truss or over truss bridges are used for longer spans. However, special methods need to be employed in the construction of a steel railway bridges such as parallel building and jacking sideways.
In order to let people watch the viwe of the sea, we can build a ferris wheel. The ferris wheel should be put in the middle of the bridge. It will be the banlance point of the whole bridge to balance the bearing capcity.
My bridge structure is very simple, but I think it is very strong. It is like a stone arch bridge, but the deck is flat, and there are fences on the bridge.
Design and Develop
We build the bridge that has two roads, one is for car and another is for train. The base consititude with 12 paper piers, and the train road has crawls. Then build the Ferris wheel on the top of the bridge
Construction in process
(1) First, we use a big wood board for our base.
Second, draw the sketch on the board. The details for which things should be where.
Third, use 502 to conglutinate the bridge piers with the board.
Fourth，we drew the base of the bridge in blue.
Fifth, build the small wood board to suport the base.
Sixth，paint the holders.
Seventh，put the bridge on the base.
Eighth，paint the body in grey.
Ninth，add the guardrail on the sides of the road.
Tenth，put another road and paint them in black.
Eleventh，make the holder for Ferris wheel between two roads.
Twelfth，make the big supports to fix the Ferris wheel.
Test and Evaluate
We use the thing that heavier than our bridge, for example we put the heacy thing on the bridge body. When we don not build the guardrail we used hands to press the body of bridge, it sagged. After that we made the holder and guardrail on the sides of the bridge to support road,and make sure it canbe enough strong to bear the weight that we gave. Actually, we succeed, we put more emphatic and it would not break.
We added Led in the Ferris wheel
A dvantage And Principle
Advantage: Make the bridge look better, the structure is more perfect.
Principle: Through the inhalation of seawater to cool, and then discharged, make railway cooling, it will not cause any pollution.
Twelfth，make the big supports to fix the Ferris whee
