Square hollow brick

Abstract

The invention relates to a square hollow brick comprising a brick body, water inlet and drain holes, surface water grooves and concave openings; the brick body is hexagonal in shape, the upper surface of the brick body is provided with the concave surface water grooves, the peripheries are communicated, and rainwater can flow into the water inlet and drain holes through the concave openings; the water inlet and drain holes are communicated with internal branched round holes, and the six internal branched round holes are communicated with an internal total round hole at the middle of the brick body. The concave openings are each designed into a shape with narrow upper portion and wide lower portion; the internal total round hole designed at the center of the interior of the brick body is cylindrical in shape, and the upper surface of the cylinder is level to the lower surface of the brick body, so that drained rainwater conveniently flows into a part of square water drain dark channel, and dedicated sewers are not required to be designed on the surface of a square. The square hollow brick has the beneficial effects that: the combination problem of the square brick and the sewers is solved; due to the hollow structure, raw materials of the brick body are saved; if one hole is blocked, due to communication of six faces of the internal total hole and the internal branched holes, water can be fed and drained from other five holes, and the problems of blockage and unsmooth drainage can be effectively prevented.

Description

technical field [0001] The invention relates to a hollow brick, in particular to a square hollow brick. Background technique [0002] At present, most of the square bricks adopt solid structure, which has the following disadvantages: firstly, when it rains, the rainwater cannot be drained immediately, and it is easy to leave accumulated water on the square; That is to say, it increases the labor cost and affects the appearance of the square ground. The above problems all need to be solved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a square hollow brick, which integrates square bricks and drainage holes, solves the problem of quickly removing water accumulation in the square, and does not need to design a special drainage channel for construction on the surface, and has Anti-blocking function. [0004] The technical solution adopted in the present invention is: a square hollow brick includes a brick body, ...
