摘要:
Concrete/mortar is manufactured with a small amount of water by using a dry clathrate water mixture. The dry clathrate water is used in a state wherein the water is impregnated into a water absorbent polymer.

A process relating to the manufacturing of a structural reinforcing material which is made of a glass fiber reinforced plastic, a carbon fiber reinforced plastic or similar material wherein a precise sectional shape is not required. A fiber body including a plurality of reinforcing fibers is impregnated with a hardenable material and subsequently introduced into a drawing die having a desired sectional shape so as to be formed into a drawn article having a predetermined sectional shape. A tape is coiled therearound so as to cover the article. A string member is coiled therearound to thrust into the surface of the article. Thereafter, the drawn fiber body is subjected to a hardening treatment and the tape and string member are removed.

A damping device has a liquid vessel into which the liquid is injected having the flattening wave motion water surface formed in such a manner that the wave motion direction of the wave motion water surface is a strecher one, damping members are provided in order to damp the sloshing of liquid in the liquid vessel, and wave dissipation devices are disposed at the portion which isn't always soaked in liquid in the liquid vessel. Accordingly, the vibration in a construction occurring by wind, earthquake and the like is absorbed by means of viscosity resistence occurring between liquid and damping member, and the vibration is restricted. Moreover, damping performance can be efficiently exercised by providing various kinds of installation forms.

A reinforcing structural material is provided made of a plurality of fiber assembly cords interwoven into a braid, each of the cords being comprised of a plurality of fibers, and the braids being impregnated with a bonding agent for bonding together the fibers and cords. The reinforcing braid is useful for reinforcing a fibrous inorganic composite providing a product which is light in weight but excellent in strength characteristics.

摘要:
A driving process for enlarging a tunnel wherein a primary shield machine is driven along an ordinary diametrical tunnel to a predetermined region to be enlarged. An enlarged starting base is formed in the rear of the primary shield machine. An enlarging shield machine is assembled in the enlarged base. Thereafter, the primary shield machine and the enlarging shield machine are both driven forward along the predetermined region of enlargement to construct an enlarged tunnel.
摘要:
A reinforcing member for civil and architectural structures is made up of a mixture of reinforcing fibers and thermoplastic fibers which become thermoplastic at a temperature which is lower than a temperature at which the reinforcing fibers become thermoplastic. The thermoplastic fibers may be mixed into each bundle of the reinforcing fibers. The mixture may be formed by arranging respective fiber bundles of the reinforcing fibers and fiber bundles of the thermoplastic fibers. It may also be made by mixing the thermoplastic fibers and an electrically conductive heat-generating wiring material into the reinforcing fibers.

Concrete/mortar is manufactured with a small amount of water by using fine polymer particles containing frozen water. The water becomes available when the particles thaw or the particles may be used directly without freezing.
摘要:
A soldified and particulated resin and a substantially solidified-state-maintained water are mixed with cement and after the mixing is finished, the solidified resin and water are liquefied and the cement is hydrated with the liquefied water. Since the resin maintains the solidified and particulated state and the water also maintains the solidified state during mixing, the mixing work of cement, water and resin is uniformly performed.
