摘要： PROBLEM TO BE SOLVED: To make it possible to inhibit a stabilizing fluid containing a carbonate as a dispersant from being deteriorated by the Ca ions in an excavation work for a diaphragm wall, an earth drill pile or the like with the stabilizing fluid and to inhibit the formation of mud film on the cut concrete surface in a work of cutting the concrete or the diaphragm wall. SOLUTION: This method is one for administering a stabilizing fluid in an excavating work for a diaphragm wall, an earth drill pile or the like or in a work for cutting the concrete of the diaphragm wall with a stabilizing fluid wherein the excavation is performed while a stabilizing fluid containing a carbonate as a dispersant is being recirculated. The carbonate concentration and pH value of the fluid are monitored. An alkali hydrogen carbonate or an alkali carbonate is added to the fluid so that the carbonate concentration may not lower to 0.05wt.% or below (in terms of the sodium hydrogen carbonate), and the pH value may fall within the range of 8-13. Thus, the carbonate concentration of the recirculated fluid can be kept at 0.05wt.% or higher, and the pH value can be kept at 8-12.

摘要： PROBLEM TO BE SOLVED: To provide cast-in-place concrete which makes necessary and sufficient strength possessed by a section from a pile head part to a pipe bottom part and which can reduce costs, and a construction method for the cast-in-place concrete.
SOLUTION: In the construction of a cast-in-place concrete pile 20, a tremie pipe 16 is inserted into an excavated hole 12, and concrete is poured into the excavated hole 12 from the tremie pipe 16. In that case, the concrete is poured while a leading end of the tremie pipe 16 is embedded in the already poured concrete and while the tremie pipe 16 is gradually pulled up. The amount of cement in the concrete to be poured is increased as the concrete approaches the bottom part 20A of a pile body, an intermediate part 20B of the pile body and the head part 20C of the pile body.

摘要： PURPOSE:To closely stick a concrete underground wall on the bottom and side faces, by arranging a steel partition formed so as to correspond to the bottom shape of the excavated groove, between the prior element and the posterior element of the cast-in-place underground concrete wall and arranging mesh sheets coming in contact with the inner wall face on the steel plate and metal laths at the outside of the sheet. CONSTITUTION:Trench excavation and slime treatment are carried out in a prior element portion 1. And a steel rod cage 3 provided with a partition plate 2 made of H-shaped steel materials are erected at both sides thereof. At that time, the front end of steel plate 2 is set to correspond to the groove bottom. A metal lath 4 and a mesh sheet 5 are attached to the side end 2a thereof so as to closely contact the excavated ground. The steel plate 2 is allowed to press in the groove bottom by its own weight and securely partition the prior element 1 and the posterior element 1'. In this way, it prevents the prior concrete from leaking to the posterior concrete and allows cement paste to ooze out of the sheet 5 and the lath 4 to improve the adhesion.
