Abstract: PURPOSE:To smoothly perform the catchment and drainage by having multiple compartments formed with void parts, locating these voids sloping down toward the central part and forming a sealed air passage on the upper part of at least one of longitudinal plates. CONSTITUTION:Catchment and drainage pipes 2, 2 are communicated by a pipe joint 3 and buried in the ground. The water in the ground enters into respective compartments 8a, 8b, 8c, 8d, 8e through void parts 12a, 12b, 12c, 12d, 12e. Since the area of the compartment 8a is large enough, the water combined by the pipe joint 3 flows into the compartment 8a. Since the air in an air passage 6 is led into respective compartment 8a, etc. through the cavity 14 of the pipe joint 3, the water in the respective compartments 8a, etc. is flowed in the longitudinal direction and while, in the pipe joint, it enters into the large compartment 8a of the central side because of its sloped shape. Consequently, the entered water goes forward the longitudinal direction, staying mainly in the compartment 8a, so as to be drained.

Title: Lightweight block
Inventor: MINE TATSURO
IPC: C04B14/16
Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To produce a lightweight concrete block by producing from a cement compsn. into which a lightweight aggregate is mixed to give a specified specific gravity. SOLUTION: The cement compsn. is prepared to have <1 specific gravity. As for the lightweight aggregate, an inorg. aggregate such as hollow glass particles is preferably used. It is more preferable to use recycled glass foam body or pumiceous sand balloon. When the objective concrete block is produced from the cement compsn. to which the lightweight aggregate comprising recycled glass foam body of particles of 0.3 to 5 mm diameters and pumiceous sand balloon of particles of 0.03 to 0.5 mm diameters are mixed, the packing rate of the aggregate increases and both of the mold releasing rate and the strength can be increased. If the concrete block is produced by vibration press-forming, the block can be instantly released from the die after formed, and increases the productivity.  By using a compsn. prepared by mixing 30 to 60 vol.% recycled glass foam body of particles of 0.3 to 5 mm diameters and 15 to 40 vol.% pumiceous sand balloon of particles of 0.03 to 0.5 mm diameters with cement paste having 35 to 50% water/cement rate, the packing of the aggregate is more efficient.
