Description

Structure for composite mudguard method with guide frame and steel pipe}

The present invention relates to a structure for a composite soil membrane construction method. More specifically, it relates to a structure for a composite soil membrane construction method provided with a guide frame and a steel pipe.

Conventionally, as a construction method for forming a barrier wall and a water-blocking wall, the CIP (Cast In Place Pile) method and the SCW (Soil Cement Wall) method are mainly used.

The CIP (Cast In Place Pile) method is also called the concrete pile method, and it is a method of forming a wall by excavating the ground, discharging the soil, inserting a reinforcing bar, and injecting concrete.

On the other hand, the SCW (Soil Cement Wall) method is a method of forming an underground wall using a cement wall and an H beam, and a hole is made at the place where the H beam is inserted, and cement, soil, and water are mixed in the hole. It is a method of forming a continuous wall and inserting H piles.

However, the existing CIP (Cast In Place Pile) method or SCW method has a disadvantage that additional processes must be accompanied, such as pouring concrete to form a wall on the excavated ground or installing H beams for structural reinforcement. .

Accordingly, it is required to develop a new structure having excellent structural safety and constructability and a construction method using the same while replacing the conventional CIP method and SCW method.
