The present invention relates to an H-type pile for pillar piles used in the ground stabilization method for securing the stability of the pit surface in the construction of the excavation work for the construction of structures such as basement or retaining wall of the building during construction or civil works. More specifically, the present invention relates to an H-type pile in which an anchor insertion hole for inserting an anchor supporting a retaining wall or an anchor insertion cutout is formed.

In general, excavation of ground in static equilibrium will inevitably cause ground displacement. Therefore, it is very important to select the ground stability method to minimize the ground displacement and deformation. In particular, the design of the masonry structure considering the magnitude, distribution and displacement of the lateral earth pressure acting on the wall is very important in the construction of today's underground structures where problems that can occur with excavation are becoming more complicated in size and contents. It is becoming important. Therefore, it is essential to select an economical and safe earthing method considering all the conditions such as the topography and geological conditions of the site.

Soil blocking method is largely divided into earth wall method to maintain the independence of the back soil sediment and the support method to reinforce it structurally, and the most popular earth wall method is the thumb pile earth plate method, CIP (Cast In Place Pile) method, There are SCW (Soil Cement Wall), Slurry Wall, and Sheet Pile. In addition, the method of supporting the retaining wall is largely divided into a beam method and an anchor method, and the beam method includes a reinforcement method and a reverse hammering method, and the anchor method includes an earth anchor method and a small nailing method.

In particular, the thumb pile earth plate method is to install a thumb pile such as H-Pile in the ground at intervals of 1 to 2 meters before excavation, and to support the collapse and earth pressure of the soil by installing the earth plate between the thumb pile at the same time as the excavation. This type is most commonly used in earth wall, but it is almost unprotected against soil deformation, soil backfill failure, groundwater, etc. If it is necessary for geological conditions, it is applied in parallel with grouting method. In addition, the earth anchor method does not require braces and braces, thus securing a wide working place, thus improving the excavation efficiency, and supporting the side pressure of the retaining wall with the anchors on the back side, so that it is easy to apply even in digging planes with irregular slope or shape have. Soil nailing method is a method developed for the purpose of providing a flexible support to the excavation surface or slope stability. This method basically inserts stiffeners that can resist tensile stress, shear stress and bending moment at relatively tight intervals without prestressing, increasing the overall shear strength of the original ground and restraining the displacements as much as possible during or after excavation work. It is a technique to limit the relaxation expected afterwards.

As a method of forming the earth wall by the thumb pile earth plate method and supporting it by the anchor method, an earth anchor method using a horizontal beam is widely known. That is, as a method of stacking a plurality of earth plate between a plurality of H-shaped steel column fixed at an arbitrary interval, the earth anchor is used to fix a plurality of H-shaped steel column supporting the earth plate to the earth wall or rock wall. At this time, the fixing of the earth anchor is installed in a horizontal beam as a horizontal beam to a plurality of H-shaped steel column fixed in the vertical direction, and fixed to the H-shaped steel band anchor anchor. In this conventional earth anchor method, since the H-shaped steel strip is necessarily installed in the lateral direction, it is necessary to mobilize a separate heavy equipment, and there is a risk of an accident when lifting the H-shaped steel belt and rotating it when using the heavy equipment. Very high. In addition, since the H-shaped steel strip is expensive, usually when a pair of H-shaped steel strips are installed at an arbitrary height on the H-shaped steel column, more than necessary materials are used to increase the construction cost. In addition, when the formal structure is integrally constructed on the earth wall supported by the earth anchor, the concrete retaining wall much thicker than the required wall thickness needs to be cast due to the interference of the horizontal beam and the reinforcing steel used in the formal structure. There is a problem that is committed.

The present invention relates to an H-type pile for the thumb pile that can be mounted to the reinforcement such as an anchor on the thumb pile itself without using a belt, while maintaining the stiffness of the joint of the H-shaped pile, that is, the web portion, An object of the present invention is to provide an H-shaped pile having an anchor insertion hole or an anchor insertion cutout for inserting a reinforcement such as a nail.
