Abstract

PROBLEM TO BE SOLVED: To prevent the penetration of dust, gravel, mud, rainwater, or cleaning water to the clearance between the outer periphery of a lid body and an inspection port to eliminate the clogging by consolidation thereof by providing a collar for blocking the clearance on the circumference of a lid body supported in the inspection port by a support member. SOLUTION: In an inspection port 2 provided at desired intervals in a passage 1, a collar 7 for blocking a slight clearance 6 formed with the inspection port circumferential wall 2a or a support frame part is provided on the circumferential upper end of a lid body 3 supported by a support frame 4. Lateral pressure moderating cutout parts 9 are provided on desired positions of the body part 8 of the lid body 3 at prescribed intervals, and a leg part 10 for supporting the lid body 3 is formed between the cutout parts 9. Since the clearance 6 formed between the inspection port part and the circumference of the lid body 3 is sealed by the collar 7 on the circumferential upper end of the lid body 3, and the lateral pressure added to the lid body 3 is moderated, not only the lid body 3 can be more easily opened, but also the possibility of contaminating a facility inspection chamber or inspection port lid chamber can be eliminated.

In the conventional inspection port cover, dust, gravel, mud, and the like are formed in a small gap 6 formed between the outer periphery of the lid 3 and the support frame 4 portion 4B of the inspection port 2. Rain water, cleaning water, etc. enter and solidify, causing clogging. After a period of time, the lid 3 sticks to the inspection port, and furthermore, side pressure is applied to the lid, so it should be easily opened. There is a problem that can not be. In severe cases, it may not be possible to open the lid by hooking the handle 3A of the lid 3 and opening the lid with a jack. In such a case, there is a problem that the lid 3 is destroyed, which is uneconomical and causes noise pollution due to noise generated at the time of the destruction.
In addition, the water that has entered through the gap 6 stains the inspection chamber below the inspection lid, or stains the second inspection lid chamber immediately below the inspection lid, such as a lid opening / closing handle, a lock, and the like provided on the lid. There was also a risk of rusting and erosion of the manhole member.

When inspecting and repairing the equipment under the floor, the lid 3 is opened, or the lid of the second inspection lid just below is opened to enter the room, and the equipment is inspected and repaired. A gap 6 formed between the cover 3 and the outer periphery of the cover 3 is sealed by the flange 7 at the upper end of the outer periphery of the cover 3, so that dust and
Gravel, mud, rainwater, cleaning water, etc. do not enter, there is no solidification and clogging, and there is no risk that the lid 3 will stick to the inspection opening. For this reason, not only can the lid 3 be easily opened, but there is no possibility that the equipment inspection room or the second inspection opening cover room will be soiled. Further, by providing the notch 9 for side pressure relief in the body 8 of the cover 3, the side pressure applied to the cover 3 is reduced, and the cover 3 can be more easily opened. Therefore, according to the present invention, the lid 3 can be easily opened and responded immediately even in an emergency without breaking the lid and generating noise pollution, thereby contributing to an improvement in safety. For example, by infiltrating the water between the flange 7 of the lid 3 and the edge of the inspection opening with caulking and a waterproof material, the infiltration of sewage is reliably prevented, and the equipment inspection room and the second inspection opening cover room are provided. Not only can further enhance the effect of preventing fouling, but also eliminate the risk of rusting and erosion of manhole members such as a cover opening / closing handle and a lock provided in the second inspection opening cover.
