摘要： PROBLEM TO BE SOLVED: To prevent a plant such as a flower plant, a tree or a plant from weakening or withering due to the forgetting of watering, etc. SOLUTION: This water-retaining mat charged with charcoal is obtained by using water-permeable and tough non-woven fabrics 1 as the front and back surface cloths of the water-retaining mat charged with the charcoal, charging non-woven fabrics, a polymer and granular charcoal as water-absorbable materials between the non-woven fabrics, wrapping the water-absorbable materials with the non-woven fabrics, and subsequently covering the water- absorbing materials with the non woven fabrics. The retention of water, the growth of the plant on the charcoal and the prevention of soil drying for a long time can be achieved only by placing the mat on the root portion of a flower plant, a tree or a plant and subsequently applying water to the mat.

摘要： PURPOSE: To improve the stability in the ground by providing a plurality of openings in a side wall of a hollow pile body and mounting a core body, in which a plurality of wedge bodies are disposed, in the pile body so that the wedge bodies are engaged with the openings. CONSTITUTION: A core body 5, to which a plurality of wedge bodies 6 and inner drive bodies 7 are attached, is put into a leading pile body 2 from a top opening thereof. And the body 5 is pushed as far as a point where the forward end of the body 6 of the body 5 contacts an opening 4 of the body 2 so as to be engaged therewith to form a pile for use in a civil construction work. And in the construction work, the pile is inserted into the ground from the forward end direction of the body 2 and the body 5 is then pushed to move it in the forward direction and the body 6 is protruded outward from the opening 4 so as to be inserted obliquely into the ground. And when the pile is driven deeply into the ground, a joint pile body 2' is connected to the body 2 through a connector 3 and a core body 5' is pushed to cause the body 6 to protrude from the opening 4 into the ground.

摘要： PURPOSE: To stabilize underground a pile under civilengineering works and prevent slipping out of the pile by forming it from a joint pile and a leading pile furnished with an opening in the side wall, and fitting a core having a plurality of wedges in each pile. CONSTITUTION: The head tip of a leading pile 2 is shaped conical, while the tail end is left open, and a connection part is formed into a single piece at the edge of the opening. The inside of each joint pile 2' is made hollow, and the two ends are left open. Further an opening 4 is bored in the side wall of each pile, and each wedge 6 furnished at a core 5 is protruded to outside the pile from the opening 4. At service, the leading pile 2 is previously driven into the earth, and a necessary number of joint piles 2' are put in connections. After completion of driving, the core 5 is pressed. The core 5 moves toward the head tip of the pile, and the wedge 6 of the core 5 protrudes into the earth through the opening 4 or 3' so that the rooted state is established.
