The present invention relates to a collecting well manhole for a median strip. The collecting well manhole for a median strip is firmly installed on a manhole joint with improved durability by preventing mortar from being mixed with air and forming bubbles while being injected. The collecting well manhole for a median strip injects the mortar without blocking an air outlet and adjusts the amount of the mortar filled in the manhole joint to completely fill the joint. The collecting well manhole for a median strip comprises a bottom manhole (10) including a bottom body (12) of which the top is open and of which one and the other bottom sides are separately joined with an inlet tube (1) and an outlet tube (2) and a first mortar filling groove (14) which is formed on the top of the bottom body (12) and of which inclination increases into the shape of V or U; and a top manhole (20) including a top body (22) with the open bottom and the top formed with a manhole cover (21), a second mortar filling groove (24) of which inclination increases into the shape of V or U at the bottom center of the top body, a mortar inlet (26) extended from one side of the top body (22) to the bottom of the second mortar filling groove (24), and a plurality of air outlets (28) extended from one side of the top body (11) to the top of the second mortar filling groove (24). Air between the first and second mortar filling grooves (14, 24) is discharged through the air outlets (28) by injecting mortar (M) which fills up the inside of the second mortar filling groove (24) from the bottom of the first mortar filling groove (14) through the mortar inlet (26). |
