Description

Apparatus for constructing bridge moving}

The present invention relates to a mobile bridge construction device, and more particularly, it is possible not only to work regardless of the ground state, but also to easily build a bridge even if the bridge to be constructed has water such as a valley, a river or a river. The present invention relates to a mobile bridge construction device that can shorten the air and significantly reduce the construction cost.

As shown in FIG. 10, in order to construct a predetermined bridge between a pair of support members 110a and 110b spaced apart from each other, a relatively large amount of equipment and a construction method are required.

First, in the state in which a plurality of pillars 103 are arranged along the transverse direction of the axis connecting the pair of supports 110a and 110b, a reinforcing block 104 is placed on the upper portion of the unit construction 105. A plurality of unit structures 105 are disposed along the axis connecting the pair of supports 110a and 110b to be spaced apart from each other.

When the unit structures 105 are arranged in a row between the pair of supports 110a and 110b, a pair of reinforcing blocks for the unit bridge blocks 101 having a length equal to the distance between the pair of unit structures 105 are provided. It is arranged continuously between the 104.

At this time, in order to put the unit bridge block 101 on the upper portion between the pair of reinforcement block 104, as shown in Figure 10, a pair of crane (120a, 120b) is used.

In general, since the unit bridge block 101 is a weight body having a relatively large length and weight, a pair of cranes 120a and 120b are prepared, and the unit bridge block 101 is provided on a tension rope provided in each crane 120a and 120b. After the end of the both ends, the pair of cranes (120a, 120b) is driven so that the unit bridge block 101 can be disposed on the top of the reinforcement block 104. In this way, if the unit bridge block 101 is completely raised in the upper predetermined position of each unit structure 105, the bridge is completed through a separate post-work.

By the way, in the conventional mobile bridge construction apparatus, it is not difficult to apply when the ground between the pair of supports is strong, but in the case of soft ground, the crane work is not easy, so the stopping work for compacting the ground is necessary. As a result, the air is increased and the construction cost is increased.

In addition, in the case where the bridge is not a general land, but in an area where there is water such as a valley, a river or a river, the crane cannot be located as a ground between a pair of supports, and thus there is a problem that the operation is more difficult.

Accordingly, an object of the present invention is to not only work regardless of the ground state, but also to easily build a bridge even if the bridge is in an area having water such as a valley, a river or a river, thereby shortening the air and significantly reducing the construction cost. It is to provide a mobile bridge construction device to reduce.
