Description

Construction method of annular foundation using edge section pipe and its foundation {CONSTRUCTION METHOD OF FOUNDATION USING RECTANGULAR PIPE AND ITS FOUNDATION}

The present invention relates to an annular base and a construction method thereof, and more particularly, to a construction method of the annular base using a cross-sectional square tube improved in strength through a change in the structure and its foundation.

In general, bridges that cross rivers or seas than bridges built in land conditions have to be constructed at the water level, so there are many constraints on the work, and underwater construction of the lower foundation is inevitable, which is expensive.

In addition, in recent years, the length of the pier is increased by the length of the bridge to reduce the underwater construction to increase the base of the lower foundation, showing a lot of construction cost differences depending on the type and construction method of the lower foundation.

In general, since the lower part is constructed with highways and shafts with soil, there is no major obstacle in construction, but the highways and shafts are difficult in deep rivers and seas, and the water barrier construction is performed in parallel with the construction of lower foundations.

Specifically, when the rock layer is present immediately, a fixed well base and a direct foundation are applied, and when the soil layer is deep, a pile foundation and a submerged well are applied.

In the case of stationary and submerged well wells, the water is generally formed using steel formwork, and in the case of pile foundations, the steel sheet pile method and the PC house method are mainly applied.

The water block using steel formwork is a method of making steel well formwork on the ground higher than water depth, submerging it in water transport and foundation position, and placing concrete inside the formwork to install steel formwork. It is a method of constructing the foundation slab installed on the top of the pile under the ground condition by cutting the channel pile on the ground to the required depth on the barge and blocking the inflow of the inside and the bottom of the pile. This method is to apply the basic slab construction to the land work. It is mainly applied to the sea where the difference between tides occurs.

In addition, as one of the techniques for constructing a conventional annular base, there is a method of constructing a temporary barrier using a plurality of cylindrical piles, but the cylindrical pile is manufactured through a process of rolling a sheet material, so the limitation of the thickness is limited. There is a problem.

Specifically, since the cylindrical pile is made by rolling a sheet, the diameter of the entire cylindrical pile is inevitably affected by the thickness of the sheet. In other words, the diameter of the entire cylindrical pile and the thickness of the plate is in proportion to each other. Therefore, the thickness of the plate is affected by the diameter of the entire cylindrical pile.

For example, when constructing an annular foundation using a cylindrical pile in an area with high side pressure, it is necessary to secure high bearing capacity by high side pressure, and the thickness of the plate needs to be thick to secure high bearing capacity. However, when the thickness of the plate is thick, not only the construction is difficult because the diameter of the entire cylindrical pile is large, but also a problem that the space secured inside the wall of the annular foundation becomes thicker than necessary may be rather small.

In addition, such a conventional water barrier method requires a lot of construction costs and a long working air, and in particular, in the case of performing a clogging operation or installation of an annular foundation in water, the operator by the pressure difference according to the pressure as well as the air pressure There was a problem that caused a diving bottle or other safety accident.

As shown in FIG. 1, the conventional water barrier method has a problem that a lot of construction cost and working air occurs, the steel sheet pile method requires a driving cost and a lot of work time because the steel sheet piles must be incorporated into the soil layer in the water surface. The submerged wells are expensive due to the use of unnecessary steel formwork, and the PC house method has the pile foundation of the steel sheet pile method into the ground, so the ground resists the horizontal displacement, while the pile foundation of the PC house method is Since it is exposed to the surface of water and has no effect on the horizontal resistance of the ground, it is necessary to put more piles than the number of piles in the steel sheet pile method. Therefore, the size of the foundation is larger than necessary and the aesthetics are not good due to the exposure of the foundation.
