Abstract

The utility model discloses a building block of an inspection well, which comprises a building block body and a connecting building block, wherein the connecting building block is formed by splicing two dovetail tenons and is of an integrated structure; two dovetail tongue-and-grooves with the same shape are respectively formed at the two ends of the building block body; and the dovetail tenons are correspondingly buckled with the dovetail tongue-and-grooves. The building block has the advantages that: a well body formed by building the building block is high in strength and permeability resistance; the inspection well is long in service life; the building block is convenient to use; the labor intensity of workers can be effectively reduced; the working efficiency is improved; and the manufacturing cost is saved.

Description

The manhole building block

Technical field:

The utility model relates to a kind of building unit, relates in particular to a kind of manhole building block.

Background technology:
