摘要： PURPOSE: To make comparison of the slime amount deposited on a widened bottom part of an excavated hole with that on a shaft part by sampling from the slime deposit on the widened bottom part and the slime deposit on the shaft under the same conditions. CONSTITUTION: A plurality of enlarged width arms 6, 7 equipped at the tips with slime sampling cylinders 10 are swingably installed in the middle part of a hung-down rod 1 to be inserted in an excavated hole H, and at the bottom of the rod 1 a bottom landing slide pipe 3 is furnished in such a way that its relative sliding amount with the rod 1 is adjustable. The arms 6, 7 are coupled with the slide pipe 3 through coupling rods 8, 9.

摘要： PURPOSE: To make it possible to reduce a construction cost by pouring a stabilizing liquid containing a deterioration retardant before placing concrete in an excavated ditch formed by pouring the stabilizing liquid in the ground, and substituting it for the stabilizing liquid in the bottom of the excavated ditch. CONSTITUTION: A stabilizing liquid A is poured into an excavated ditch 2 while excavating the ditch 2. A reinforced cage is lowered into the excavated ditch 2 formed in a specific shape and is erected in a specific position, and a specific number of tremie pipes 4 are installed. The stabilizing liquid A is sucked up with a pump 6, a deterioration retardant is added to the liquid A to make a stabilizing liquid B, it is supplied to the tremie pipes 4, and it is poured to the bottom of the excavated ditch 2. After that, concrete 8 is poured into the tremie pipes 4, the stabilizing liquid B filled into the pipes 4 is pushed into the excavated ditch 2. The stabilizing liquid B is pushed into the excavated ditch 2 in parallel with the cast of the concrete 8. The stabilizing liquid A is discharged with the pump 6 in parallel with the cast of the concrete 8, and the concrete 8 is placed into the excavated ditch 2 until it reaches specific height, while the stabilizing liquid B in a deteriorated part caused by contact with the concrete 8 is collected to abolish.

摘要： PURPOSE:To remove efficiently a muddy film formed on an excavated wall surface of a continuous underground foundation. CONSTITUTION:A guide rail 25, which is formed in a part of a joint member buried on the side ends of a preceding element of a continuous underground foundation, and an engageable guide member 20 are installed to the side surfaces of the foundation and suspended with a hanging wire 39 from the ground. A support beam 30, which supports a brush 32, whose end is laid out so as to come in contact with a groove wall surface at the position of a joint between the elements of the continuous underground foundation, is fixed with a main frame 10, which may rise along a guide rail 25 by winding up and unwinding the hanging wire 39 in the groove where the continuous underground foundation is constructed. A muddy film formed on the groove wall surface is scraped and removed with the brush 32 which moves vertically by accompanying the lift motion of the main frame 10.

摘要： PURPOSE:To provide a concrete placing height measuring unit which has a simple structure so as to be manufactured at a low cost, which has an unlimited measuring range, and which can carry out measurement even though a hindrance such as reinforcement or if it is inclined, and which can not be affected by an environmental temperature or the like, by providing an integrating flowmeter in an outflow pipe connected to the upper end of a flexible tube in which liquid is enclosed. CONSTITUTION:Before placing concrete, a flexible tube 8 is filled therein with liquid 8 having a pressure equal to that of liquid 13 outside thereof, and accordingly, it is held in an inflated condition. After placing concrete 14, the flexible tube 7 is collapsed by the weight of the concrete 14, and accordingly, the liquid 8 in the tube is depressed. A part of the liquid 8 corresponding to a decrease in the volume of the tube 8 due to the corruption thereof, is led to through the outflow tube 9 to an integrating flowmeter 10 for measuring the quantity of the part of the liquid 8. That is, the quantity of the liquid discharged from the tube 7 is measured as a variation in the placing height of the concrete. With this arrangement, it is possible to simply and inexpensively manufacture the concrete placing height measuring unit which has an unlimited measuring range and which can carry out measurement even though a hindrance is present.
