摘要： PURPOSE:To construct a composite foundation pile having a great bearing capacity in a short time by a method in which a pit with an expanded bottom is excavated, concrete is placed to the expanded bottom, and a custom-made pile having a shoe on its tip is penetrated into the pit. CONSTITUTION:Excavation is made to form an expanded bottom reaching the bearing stratum, and concrete 2 is placed to the expanded bottom B to form a cast-in-place concrete pile 2 of a large diameter. A custom-made concrete pile 3 of a small diameter is penetrated into the pile 2, and its bonding strength with concrete is increased by a shoe 4 provided to the tip of the pile 3. Since the pile 3 and the pile 2 are integrally formed, the pile having a great supporting capacity can be constructed in a short time.

摘要： PURPOSE:To raise the self-standing property of an underground continuous wall as well as to suppress the early-period subsidence of the wall by a method in which a hollow is formed in the underground continuous wall, and earth anchors are provided in the hollow to give it a post tension force. CONSTITUTION:A trench 1 for an underground continuous wall of an expanded width is excavated in a given place, and an iron bar cage 3 in which a hollow pipe 2 is vertically set is erected into the trench 1. Concrete 4 is placed and hardened, and then an earth anchor hole 5 is drilled in the ground through the hollow pipe 2 by means of a boring machine. Afterwards, an anchoring grout is injected, an anchor steel material 6 is inserted to form an earth anchor, and after the concrete 4 hardens, post tension is given to the anchor in order to construct an underground continuous wall. A self-standing property can thus be given to the underground continuous wall.

摘要： PURPOSE:To reduce the cost of solidifying work on the surrounding of a pile by a method in which a custom-made pile having a mud water solidifying agent layer on its periphery is erected into an excavated pit and cured until the surrounding of the pile is solidified upon reaction of the solidifying agent with the excavating mud water. CONSTITUTION:A solidifying agent layer 2 of cement, aluminum powder, iron powder, etc., is beforehand coated or bonded with the periphery of a custom- made pile 1. The custom-made pile 1 is erected into an excavated pit and cured until the surrounding of the pile is solidified by reaction of the solidifying agent with the excavating mud water to form a solidified ground 3. Since any solidifying liquid for the surrounding of the pile is not used, the disposal treatment of wastes can be eliminated and the solidifying work is easy. The cost of the solidifying work can thus be reduced and strong ground to earthquake can be formed.

摘要： PURPOSE:To reduce the cost of solidification work of the surrounding of a pile by a method in which a water-soluble material bag filled with a mud water solidifying agent is wound around the periphery of a custom-made pile and fixed, and the custom-made pile is erected into an excavated pit and cured until the surrounding ground of the pile is solidified. CONSTITUTION:A solidifying agent 3, e.g., cement, aluminum powder, iron powder, etc., is packed into a cylindrical or flat bag 2 made of a water-soluble paper, film, woven fabric or nonwoven fabric. The bag 2 is wound around the periphery of a custom-made pile 1 and clamped with an iron plate 4, and then the custom-made pile 1 is erected into an excavated pit 1. When the bag 2 absorbs the excavating mud water, the bag 2 is dissolved, the solidifying agent 3 is dispersed into the mud water and reacted with the mud water, and the mud water with the agent 3 is dried and solidified to form a solidified surrounding body 5 of the pile. Since a solidifying liquid for the surrounding of the pile is not used, the disposal operation of wastes can be eliminated, and the solidifying is easy. The cost of the solidifying work can thus be reduced.

摘要： PURPOSE:To provide an excavator capable of excavating at constant width and to simplify mechanisms thereof by adopting a wide cutter composed of a number of protruded bits around a rotating cylinder. CONSTITUTION:The main part is composed of main cutters 2 and wide cutters 4 arranged at both sides of the main cutters 2. Said wide cutter 4 is composed of a number of protruded bits 6 around a rotating cylinder 5 supported with a horizontal axis 8, and is arranged for being pushed out obliquely downward from an excavator body 1. The required excavating work is carried out utilizing the cutter composed in this way.

摘要： PURPOSE:To improve rigidity and accordingly increase safety of an underground structure by connecting the underground structure of a building in a unitary body with continuous underground walls by means of shear keys fixed to widened portions at the middle depth of the said walls. CONSTITUTION:While digging a continuous trench 1, reguired trench width is partly widened at planned positions 3, 4 for constructing the structure. Reinforcement assemblies 5 fitted with shear keys 6 are then positioned inside the trench 1 and concreted thereafter. Next, the structure 8 is constructed after digging the ground and is connected with the concreted wall through the aid of the protruded sear keys 6.
