DEVICE FOR PROCESSING DRAINAGE OF CONCRETE STRUCTURE

摘要

PURPOSE: A drainage processor of a concrete structure is provided to sufficiently drain water by preventing the inflow of concrete into a drain pipe at a pouring of the concrete and the inflow of earth into the drain pipe after finishing a construction. CONSTITUTION: A drain pipe(101) is installed inside a concrete structure to form a weep hole. An inner cap(200) is installed in an inlet of the drain pipe. The inner cap comprises a disk part and a cylindrical pipe inserting part. The disk part has many perforation holes to drain water. The cylindrical pipe inserting part is integrally formed with the disk part. An outer cap(300) is installed in an outlet of the drain pipe. The outer cap comprises a disk part to be contacted and fixed in the inside of a mold(105) and a cylindrical pipe inserting part to be integrally formed with the disk part. Thereby, the inflow of concrete and earth into the drain pipe are prevented. Therefore, the drain function is maintained certainly.
