摘要： PROBLEM TO BE SOLVED: To construct lining in intimate contact with natural ground and to reduce construction period and cost by solving problems with tunnel lining method, such as packing of backfill in lined segments, the leakage of concrete in ECL method, the accuracy of filling inside natural ground, generation of dust and bouncing in spraying method, and the quality control, etc., of sprayed material, and by simplifying constructing processes. SOLUTION: As a shield is advanced, an inner form 5 is assembled in the form of a ring, a water-permeable bag 6 is placed, and concrete 7 is pressurized and placed in the bag 6 within a space surrounded by a press ring 4 installed on the working face side of the inner form 5, the inner form 5, an existing lined body 8, and natural ground, to form ring-shaped concrete lining 8 to provide a lined body. The bagged concrete is swollen throughout a predetermined range by pressurization, the concrete in the bag 6 is dewatered, and thus solid bagged concrete lining 8 is easily formed, whereby a highly accurate tunnel shell can be constructed in a short construction period at low cost.

摘要： PROBLEM TO BE SOLVED: To provide a caisson type pile method making use of packed concrete capable of eliminating voids between earth retaining material and bedrock hole wall, eliminating a backing material and carrying out simple execution in sound work environment. SOLUTION: Water permeable ring shaped bags 20 are arranged along a hole wall of an excavated hole to cast concrete. Water is dewatered by casting pressure to form packed concretes 21. Repeating the constitution, the packed concretes 21 are piled up and down to use them as an earth retaining material. The bag is swelled in a state to project onto the outside of a ring, and it is tightly contacted to the hole wall and is dewatered to harden. By the constitution, in a caisson type pile method for a caisson type pile and shaft excavation, the collapse of a bedrock hole wall is prevented, the conventional execution of the backing material can be eliminated, and execution with safe and high economic efficiency can be carried out. Since water is only permeated, the sound work environment can be realized.

摘要： PROBLEM TO BE SOLVED: To construct a pier capable of reducing the construction period by pressurizing and dehydrating ready mixed concrete immediately after placing it and early developing the early stage strength and early demolding, causing neither excess water on the surface of concrete nor laitance due to bleeding, and curtailing the construction joint work time.
SOLUTION: A water permeable form 3 is installed in a position where ready mixed concrete is placed and the placed concrete is pressurized and dehydrated to construct a columnar structure. A water permeable sheet 1 permeating water in ready mixed concrete and a water permeable form 3 that a reticular body 2 such as an expanded panel or the like supporting the sheet is assembled by reinforcing members are used. A fabric or the like having a function permeating water in the ready mixed concrete is used for the water permeable sheet 1. When pressurizing the ready mixed concrete placed in the water permeable sheet 1, as water in the ready mixed concrete is discharged, solid self-supportable concrete having nearly 0 cm in slump.

摘要： PURPOSE:To obtain an impervious sheet having a high impervious performance and a high flowing water resistant performance by clamping a water absorbing and swelling inorganic substance with a permeable sheet and a semi-permeable sheet. CONSTITUTION:An adhesive 4 which shows elasticity at an ambient temperature, is applied, spray coated or spiral-coated on a resinous sheet 1 made of porous rubber, for example. One layer of water absorbing and swelling inorganic substance, such as bentonite, which is granulated and treated preferably to a thickness of 0.5 to 5.0mm, is installed to the sheet preliminarily. When a plurality of layers are installed, an adhesive is applied on the first layer, and then a bentonite layer 3, for example, is formed in the case of the second layer. This process is repeated one after another. The final layer, for example, the bentonite layer 3 is coated with an adhesive. Then, a permeable sheet made of natural fiber textile 2, for example, is laminated thereon. An impervious sheet is available by applying roll pressure as occasion demands. This structure makes it possible to secure impervious properties even when rain falls during construction work and hence prevent the flow out of bentonite 3, for example.

摘要： PURPOSE:To provide a jointing method of a water-barrier sheet easy to joint and excellent in water-barrier property. CONSTITUTION:A water-barrier sheet is placed on a basis. After its fringe surface is swelled to form a gel layer 9, a water-permeable sheet 1 part of a prescribed width is stripped. An adjacent water-barrier sheet 5' is overlapped on the exposed surface to form a joint. The joint thus formed is covered with soil, and water is added to unify the joint by the swelling of a water absorbing inorganic material 2. By previous swelling of the fringe surface of the water- barrier sheet, the water-permeable sheet part of the prescribed width can easily be stripped, and by overlapping the water-barrier sheet on the exposed surface, the unification of the joint can be easily and promptly accomplished. Moreover, the water-stopping property of the joint is sufficiently secured.

摘要： PURPOSE:To obtain a water impervious sheet which can be manufactured at any desired thickness by coating high water absorbing inorganic particles having a predetermined particle diameter to the water permeable sheet having a predetermined strength with the specified adhesive showing the elasticity at an ordinary temperature, and forming a sheet as a plurality of layers which consists of multiple sheets coated with the high water absorbing inorganic particles. CONSTITUTION:High water absorbing inorganic particles 2 are distributed between an upper and a lower water permeable sheets 1, and the adhesive 3 is distributed fibrously between layers of the inorganic particles 2 to form a water impervious sheet. The hot-melt adhesive 3 is sprayed like a spider's net on the permeable polyester non woven fabric 1 having a tensile strength at about 30kg/5cm width, and thereafter, bentonite granulated products, which has a particle diameter of about 1.5mm and a length of about 2.5mm and shows the elasticity at an ordinary temperature, are stuck immediately at a predetermined thickness. This process is repeated sometimes to laminate the permeable polyester non woven fabric, and they are rolled by a pressurizing roller to form a water impervious sheet having a thickness of about 15mm. A permanent water impervious sheet having high reliability and any desired thickness is thereby obtained.
