摘要： PURPOSE:To prevent separation in water and retain high fluidity and construct a homogenious and high strength underground continuous wall, by adding a high performance water reducing agent and gellan gum when placing concrete to an excavated ground. CONSTITUTION:Concrete is placed in an excavated ground charged with a stabilizing liquid and provided with arranged reinforcing rods to construct a underground continuous wall. In this time, a high performance water reducing agent or a high performance water AE reducing agent 0.1-4.0wt.% and gellan gum 0.01-0.5wt.% is added against unit cement weight respectively. And slump flow is made 50-70cm. In this case, it is favorable that gellan gum is a dried powder composed of polysaccharide originated from microorganisms produced by aerobic fermentation of ATTC 31555 bacteria of alkaliguenus strain.

摘要： PURPOSE:To confirm the filling state of concrete in a framework in placing with an optical sensor. CONSTITUTION:An optical sensor 3, wherein a light emitting part 11 and a photodetector part 12 for the light emitting part are provided through a gap 4, is fixed at a position where the sensor is embedded in concrete 1 in a concrete placing framework 1. In response to the filling of the concrete 2 in the inside of the gap 4, the light from the light emitting part 11 is shielded. The filling of the concrete at the position of the optical sensor 3 is confirmed by changing the constants of the photodetector part 12, e.g. the resistance value of a photodiode 14. It is preferable that the presence or absence of the conduction at the photodiode 14 of the photodetector 12 is displayed on a display device 5.

摘要： PURPOSE:To prevent the breakdown of a loose ground by inserting and clamping rock bolts from the inside of a tunnel into a bedrock against the circumferential wall of the excavated tunnel at necessary intervals. CONSTITUTION:A bolt 4 having the overall length longer than the depth of a hole is inserted into a bore with a downward opening among bores bored in the necessary depth with a drill, first of all, grout 5 without welan gum is injected into a gap between the bore 3 and bolt 4, and successively welan gum added grout 6 is injected. A bearing plate or a washer 7 is applied to the projecting end on a tunnel side of the bolt 4, and the bolt is clamped with a nut 8. After a certain amount of grout 5 without welan gum is injected, a certain amount of welan gum is added to the inside of a pump 11 or the inside of a conveying pipe 10, and successively welan gum additive grout 6 is injected, so that continuous switch system injection control is made.

摘要： PURPOSE:To construct the captioned wall of uniform quality and enough watertightness easily by giving primary transition pressure to asphalt (Ap) mixture to attain given width and thickness to pave the existing surface of Ap core, and, after laying uniformly transition material on both sides of Ap core and giving transition pressure thereto, further applying secondary transition pressure to Ap core. CONSTITUTION:Ap core paving device A is moved forward in the longish direction of dam and existing surface of Ap core is heated to melt by heating device 13. Meanwhile, Ap mixture supplied from hopper 11 to hopper 22 is sent to Ap core thickness adjusting device 23, next, to form adjusting plates 21a, 21b and then to vibration tighting device for transition pressure 24 to be given primary transition pressure, and after that is laid on the surface of existing core. With progress of device A, core reaches transition (T) material uniformly laying device 3, where, based on material T and device 3, is scattered to be laid naturally and uniformly on both sides of core. Then material T is given ransition pressure by vibration tightening devices for transition pressure for material T B-1, B-2, while Ap core is given secondary transition pressure by vibration tightening device for transition pressure for Ap core C.

摘要： PROBLEM TO BE SOLVED: To prevent the spoiling of self restoring function even when there are irregularities at the laying place of a sheet by a method wherein water impermeable sheets, made of synthetic rubber, high-density polyethylene and the like, are provided on the surfaces of a water absorbing and inflating layer while layers, consisting of long-fiber non-woven fabric, are provided on the upper and lower surfaces of the sheet main body. SOLUTION: A sheet main body 1 is formed of the layer of a material 1a having water absorbing and inflating property and water impermeable sheets 1b of synthetic rubber, high-density polyethylene and the like, provided on the surfaces of the material 1a. A sheet, consisting of water inflating rubber, into which water absorbing resin is kneaded and which is pinched by synthetic rubber sheets from upper and lower sides thereof, or the sheet of rubber or high-density polyethylene, on which the layers of water absorbing inflating material, such as bentonite and the like, are bonded, for example, are used. A sheet 3 is obtained by providing the layers 2a, 2b of long-fiber non-woven fabric on the upper and lower surfaces of the sheet main body 1. Polyester fiber or polypropylene fiber and the like, for examples, are employed for the material of the long-fiber non-woven fabric.
