The present invention relates to a pile pillar, and more particularly, by attaching a porous grouting pipe to a pile made of rust-treated steel or steel pipe to grind after grounding or press-fitting the ground, thereby improving peripheral ground and increasing end support. At the same time relates to a pile pillar using a porous grouting pipe to form the pillar of the structure.

There was a problem that the construction cost and the construction period were very high by performing the grandoting after the drilling work or constructing the foundation concrete after digging in a wide section to secure the bearing capacity in the case of independent foundation.

In order to solve the above problems, the present invention attaches a porous grouting tube so that it is pulled in together when the pile is pressed or struck, and without reinforcing the pile support and reinforcing and improving the support of the surrounding ground as well. The purpose is to increase the effect together and form the foundation, and to increase the rigidity of the column by filling the inside of the support column with concrete.

Another object of the present invention is to connect to the support pillar of the upper structure using a high support force or to form a pillar to support the upper structure using the pile itself by filling the inside of the support pillar with concrete The purpose is to increase the rigidity of the column.

In order to achieve the above object, the pile pillar of the present invention is welded by attaching a porous grouting pipe to the rust-treated steel or steel pipe, and after fixing the steel rod to prevent the inflow of foreign matters when navigating into the grouting pipe, the foundation ground It is characterized in that the grouting is carried out after direct driving or pre-injection by means of excavation, and the concrete is filled in the support pillar of the upper structure.

Welding the grouting pipe to the rust-proofed steel or steel pipe pile (Fig.1.①) and inserting steel rods to prevent foreign substances from entering (Fig.2.③) After installation (Fig.3.⑤), remove the steel rod to prevent foreign substances from entering, and then insert the cap (Fig.4) and insert it to the tip of the ROD (Fig.3.⑥) for high pressure injection (Fig.3.⑦) While pulling the high pressure slowly (Fig. 3.3.⑧, ⑨) to secure the tip support and peripheral support. Repeat the operation of Figure 3 to form the front foundation as shown in Figure 5.

Fig. 6 secures the tip and surrounding support by grouting by the porous grouting pipe to the height to be inserted into the ground, and forms the column by directly using the exposed part as a pier or connecting with the pillar of the upper structure. .

Fig. 7 shows the axial deformation of the column by filling it with concrete (Fig. 7.15) in the interior of the stake pillar that directly supports the superstructure or the pillar that connects to the pillar of the superstructure, as illustrated in FIG. To suppress the formation of refractory and earthquake resistant structures (Fig. 7.14).

The present invention by attaching a porous grouting pipe (Fig. 1 .②) to the rust-treated steel pipe or section steel (Fig. 1. ①) to improve the ground without additional drilling work for grouting (Fig. 5, ⑪, 6, ⑩), using the high bearing capacity of the pile pillars to connect to the pillar of the upper structure (Fig. 6, ⑩, ⑫, ⑬) or the pillar pillar itself is the pillar of the upper structure It can be used for the construction of refractory and seismic structures (Fig. 6.4), which fills the inside of the column (Fig. 7.15) to suppress axial deformation and torsion (Fig. 7.14).

In addition, the construction of the present invention to the ground foundation in the soft ground by the group pile (Fig. 5. 으로서) by the prevention of unequal settlement and improvement and reinforcement of the soft ground.

Claims (2)

Steel rods for attaching porous grouting pipes (Fig.1.②) to steel pipes or section steels (Fig. (Fig.2.③), rod with fixable pinhole and clamp (Fig.2.④), stopper to check the discharge of grout material (Fig.4) Independent foundation, front foundation formation, ground improvement and reinforcement using piles using porous grouting pipes as construction methods (Fig.3.⑩, Fig.5.⑪, Fig.6, ⑩). Using the pile function of the present invention to directly support the upper structure (Fig. 6. ⑫) or to connect with the support pillar of the upper structure (Fig. 6. ⑬) to form a pillar and the inside of the column using concrete By filling (Fig. 7.15), the deformation of the pillars is suppressed and a fireproof and seismic structure is formed (Fig. 7.14).
