Description
Technical field
The invention belongs to building machinery application, and in particular to PLC dual controls in a kind of high water-permeable brick production in sponge city
Lowering or hoisting gear and its control method.
Background technology
With the propulsion of urbanization process, cell square quantity is continuously increased, and the living standard of people is improved constantly, with building
The corresponding auxiliary facility constantly improve in area, between block, the Condom such as road, square is also more and more.
Granite, Dali are mainly used in the ground in city square, commercial street, pavement, community activity ground, parking lot etc. at present
The fluid-tight material laying such as stone, glazed tile, cement and pitch, the harm in the face of urban environment is very big fluid-tightly.Under
During rain, waterproof ground prevent rainwater directly infiltrate through ground, completely ponding make one trip become very inconvenient；Precious
Expensive water resource has increased the burden of municipal drainage facility finally as drainage pipeline flows away；A large amount of losses of rainwater cause ground
Lower water level is difficult to, and directly influences the health of urban vegetation so that the ground flora in city is difficult to normal growth, increases
