周囲に土を埋戻して使用される。b. Conventional technology In general, for this type of manhole, a chestnut foundation etc. is cast at the bottom of the excavated ground, a bottom slab block is laid on this foundation, and a square block or straight wall is placed on top of this bottom slab block. It is constructed by sequentially stacking a plurality of concrete blocks such as blocks and sloping wall blocks, and is then used by backfilling soil around the blocks.

ｉに接合しておかないと埋戻し作業中に各ブロック間に
ずれが生じるという問題がある。However, recent backfilling work is carried out using heavy machinery such as bulldozers, so uneven earth pressure tends to act on the stacked blocks during the work. Therefore, unless the blocks are strongly joined to each other, there is a problem that a shift occurs between the blocks during backfilling work.
