The present invention relates to an underground clam or mud pile and a method of constructing a mud or mud membrane using the same by spraying a high-density material through an officer to fill gaps between piles and to completely collapse the order and soil.

When digging in order to build various structures, a plurality of piles or piles for piles are connected in order to prevent the ground from being collapsed by soil or groundwater. In this way, a continuous pile of water-based or earthquake piles form a wall in the ground, so that during construction, a water-block or earth-block may be used, and after construction, formwork may be fixed or form part of a wall.

The structure of the pile or soil pile file has a structure of a tube with steel frame embedded to increase rigidity inside a polygonal or circular body in which a rod insertion hole is formed in which a drilling rod is inserted in the center thereof, and each of them is embedded in the ground one by one. As a result, a water barrier or an earthen wall is formed.

The construction method using this method is a repetitive operation in which a drilling rod is inserted into a rod inserting hole, and a file is buried in the ground while excavating, withdrawing a rod, inserting another file, and reinserting it into an adjacent position of a pre-inserted file. Towards the surface, the underground water barrier or the soil wall, in which a plurality of piles are connected, is formed.

However, no matter how close the construction between the pile and the pile wall using the pile, the gap between the pile is bound to be formed, there is a problem that water or soil flows through the gap, the ground collapses.

In particular, in the case of embedding a circular pile inside the circular drilling pipe and embedding it in the ground, the excavation is carried out while the circular drilling pipe and the drilling rod are inserted into the ground, and then the drilling rod is withdrawn, and then the circular pile is inserted, When the excavation pipe is drawn out, at this time, a space equal to the thickness of the circular excavation pipe is formed, and there is a risk that the water or earthquake work in the ground where the groundwater is inefficient is ineffective and the entire structure collapses after the construction of the structure.

An object of the present invention is to solve the conventional problems as described above, by installing a spray pipe formed with a plurality of injection holes in the pile for the water film or soil film, after embedding one pile in the ground or a plurality of water film Alternatively, after forming the earthen wall, the high-density material is sprayed by the injection pipe to fill the gap between the piles to prevent the flow of soil and groundwater to prevent the collapse of the ground. To provide a construction method.
