Description

Cap module-based column wall for building foundation}

The present invention relates to a column-type wall, and more specifically, by installing a cap module on a column-type retaining wall pile for excavation, the retaining wall pile is utilized as a permanent pile foundation for a building, thereby enabling the construction of building foundation piles. This relates to a column-type wall including cap modules used as a building foundation, which reduces the number of units, shortens the construction period, and reduces construction costs.

Generally, in construction or civil engineering sites, temporary earth retaining facilities are installed in the excavation area by carrying out earth retaining construction to prevent the surrounding soil from collapsing. These temporary earth retaining facilities include earth retaining walls built along the excavation surface. The earth retaining walls include methods using H-piles and earth plates, column-type earth retaining methods, sheet pile methods, slurry wall methods, etc. It is constructed with

Here, the construction method using H-piles and earth plates is a method of forming an earth retaining wall by driving H-piles at regular intervals and then blocking the spaces between the H-piles with earth plates.

In addition, the column-type earth retaining method is a method of forming a column-type earth retaining wall by continuously driving in-situ concrete piles or ready-made piles. These column-type earth retaining methods include the CIP (cast in place pile) method, which involves excavating the ground, inserting rebar into the inside of the excavated hole, filling it with aggregate, and then injecting mortar to construct the pile on site; There is a SCW (soil cement wall) method that mixes soil with cement paste and then presses in H-piles or rebar.

The sheet pile method is a method of forming an earth retaining wall by connecting plate-shaped piles in succession, and the slurry wall method uses a stabilizing fluid when excavating the ground to prevent collapse of the ground, inserts reinforcing bars into it, and pours concrete. This is a method of continuously installing concrete retaining walls.

In particular, among the column-type earth retaining methods, there is a method that uses earth retaining walls as permanent building walls. However, since there is currently no way to use the column-type earth retaining method as a permanent pile foundation for a building, an additional pile foundation must be constructed around the building. In particular, the number of pile foundations required to be installed around buildings is increasing due to the strengthening of earthquake-resistant foundation design. Therefore, the cost of pile foundations that must be installed around the building also increases. In addition, when installing an underground building using the column-type retaining method, there is a problem that it is very difficult to construct a pile foundation around the building underground due to the size of the equipment.
