Description

Deformed sheet pile and its installation method {Post pile and Sheet Pile combination}

The present invention relates to a deformed sheet pile and a method of installing the same, and more particularly, when an underground excavation work is performed in the basic construction for various buildings, inserting an H type pile into the ground, and the H type pile Insert the seat pile with seat pile connection hook adjacent to the ground, install temporary block structure inside the ground, and proceed with underground excavation to make the ground stable. Soil and groundwater to collapse and ground due to instability of ground It relates to a deformed sheet pile and its installation method to prevent the inflow of water.

In general, excavation work is carried out with a certain depth to the lower side of the ground in order to build the underground structure of the building, and during such excavation work, temporary earthquake structures to prevent the earth wall from collapsing due to earth pressure or water pressure by the excavation. The installation work is being done in parallel.

In the construction of temporary cladding structure, there were problems of ordering, settlement, lack of free space at the border of adjacent land, construction period and material loss in the existing construction method (H-Pile + earth plate). The method was used.

The sheet pile method is not a plate concept when constructing a wall of a wall, but a method of creating a wall structure by a continuous construction method of engaging a plate of a small pile concept. That is, this is by the continuous type of the sheet pile (Sheet Pile) of the same width as compared to the earth plate method has the advantage that the order effect is improved and settlement problems can be solved. However, in this method, since the construction of the sheet pile is continuous type, the construction speed is very slow, and the sheet pile is inevitably cut in the middle of the construction by the one-way continuous construction. The problem of air delay and material cost was enormous, as it had to be calibrated. In addition, the existing sheet piles have a very small allowable bending stress in the direction of the shaft, so that all of them must be inserted to a certain depth to cope with the main earth pressure. Therefore, there are problems such as air delay and material cost increase.

In addition, the sheet pile used in the sheet pile construction method has a curved shape, not a plate shape, with connecting rings at both ends. In theory, steel sheet can be used for recycling, but in practice, it can be used only once or twice. The curved part is unfolded or the ring is deformed, which makes it difficult to recycle.

This is to prevent the inundation and excavation of soil and groundwater due to instability.

When the present invention is used, the ground is excavated after the deformation sheet pile is installed, so it may be effective for stabilization of the ground, and the sheet pile inserted between the H-shaped piles may be used by connecting one or two or more grounds. Depending on the state of use, the utilization varies. In addition, since the degree of function is increased, the problem of the conventional earth plate method can be solved. In addition, compared to the existing sheet pile method, semi-permanent materials can be recycled, thereby reducing the waste of resources as well as recycling the materials used in the existing sheet pile method. In addition, the existing sheet pile method requires the incorporation of individual sheet piles up to a certain depth, which reduces the economic efficiency. Economical in time and cost.
