Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prefabricated steel cofferdam,

The present invention relates to a single-structure prefabricated steel flywheel, and more particularly to a method of constructing a low-grade flywheel assembled with a plurality of lower caisson members, made of steel, A prefabricated steel flywheel having a single structure composed of a plurality of upper caulk members formed of a steel material having a single structure and a single upper end flywheel composed of two or more stages, And can be easily assembled by using a C-channel.

In general, bridges that cross river or sea than bridges constructed in land conditions require construction work in watercourses, so there are many constraints on work and construction costs are inevitable due to inevitable underwater construction of the lower foundation.

Recently, in order to reduce underwater construction, the length of the bridge piers has been reduced to make the bridge length larger, so that a lot of construction cost difference is shown according to the type of foundation and the construction method.

Generally, low water depths do not hinder the construction because the soil is constructed and the shaft is constructed and the lower part is constructed. However, in the river or sea where the water depth is deep, the road and shaft are difficult to construct.

The bottom foundation type and the membrane construction method are different according to the case where the rock layer which is the base layer of the lower foundation exists directly on the ground and the soil layer is thick on the rock layer.

If the rock bed is present immediately, the basin and the foundation are applied to the basin. If the soil layer is deep, the pile foundation and the sink basin are applied.

In the case of pile foundation, steel sheet pile method and PC house method are mainly applied.

The waterfall using the steel formwork is made by making a steel puddle form from the land higher than the water depth, and then carrying it to the water conveying and roughing the base position, and then placing the concrete in the formwork by constructing the steel form puddle. A pile house method is a method of constructing a foundation slab installed on the top of a pile by blocking the inflow water of side and bottom by putting the steel sheet pile on the ground as much as the required depth on the barge. So that the construction of the foundation slab becomes a land-based operation, and it is mainly applied to the sea where the difference of the tide interval is large.

However, such a conventional membrane planting method has a problem of generating a lot of construction cost and working air, and the steel sheet pile method has a drawback in that a steel sheet pile is required to be inserted into the soil layer in the water column, The pilehouse method is based on the assumption that the pile foundation of the steel sheet pile method is embedded in the ground and the ground is resistant to horizontal displacement. On the other hand, the pilehouse method of pilehouse method is exposed to the water And the pile is larger than the number of piles in the steel sheet pile method. Therefore, there is a problem that the foundation scale is larger than necessary and the appearance of the foundation is poor.

The existing caisson method has difficulty in assembling, and it is difficult to install each member because it is not horizontally installed when assembling the members, and there is a problem in that the caustic film is filled with the inner and outer pressure liner concrete when the aqueduct concrete is cast.
