Description
Technical field
The present invention relates to bridge field, especially a kind of flexible pontoon bridge that can stretch and can realize fast erecting.
Background technology
Pontoon bridge ancient times is called boat beam. It replaces bridge pier with ship boat, therefore there is the title of " floating boat ", " floating purlin ", " bridge of boats ", belongs to provisional bridge. Due to the characteristic of pontoon bridge, be militarily often employed, therefore claim again on " war bridge ".
Traditional pontoon bridge all needs to have the boat that can suspend or case as supporter, and this just need to all be fixed into each supporter one, also needs supporter and pontic to fix, otherwise easily causes supporter to separate with pontic, occurs dangerous. Supporter is all fixed into one, the time needing is longer, and fixed support body is also more difficult in water. Also need other equipment to transport supporter, and can only be fixed one by one, set up cumbersome.
The erection mode of tradition pontoon bridge, hinder the popularization of pontoon bridge, also given and substitute by increasing other bridge, if can solve pontoon bridge and set up the problem of speed, just can highlight the characteristic of pontoon bridge, pontoon bridge is applied, in emergency situations, can be played the effect of fast open passway, when especially speedily carrying out rescue work, can play the effect of life passage.
