Permanent underdrainage structure and permanent underdrainage method of construction of ground

摘要

The present invention relates to a permeable concrete structure and a connection terminal, and a perpetual drainage structure using a perforated pipe and a permanent drainage method thereof, due to the permeable concrete (10) and the permeable concrete (10) The connection terminal 11 mounted on the formed space 10a, the hole pipe bundle 12 connected to the connection terminal 11, the permeable concrete 13 to be poured into the space 10a, and the permeable concrete ( 10) (13) It is composed of an impermeable waterproof coating agent 14 installed on the upper surface and a water collecting well 23 connected to the end of the perforated pipe 12a. Without any separate work, it smoothly handles the infiltration water flowing from the basement, reduces the cost of construction by reducing the thickness of the foundation and the thickness of the foundation floor, and the amount of gravel. It is related to the foundation floor permanent drainage to enable the external inspection of the blockage of the pipeline due to foreign substances, and to clean the pipeline of the perforated pipe with equipment from the outside when the pipeline is blocked.;Permanent drainage system, perforated pipe, underground infiltration, permeable concrete
