The concrete mixing station is an important part of the construction process and plays an important role in the smooth development of the construction project. It is of great significance to strengthen the control of pollution during the construction process and achieve green environmental protection. Below, Lianhua Company will talk about the main points that need attention in the construction of concrete mixing plant area:
1. The construction land of concrete mixing station should be reasonably laid out, away from residential and densely populated areas. With the development of the city, environmental protection requirements have become more stringent, and some cities have required the relocation of production enterprises with serious noise and pollution to areas far from the urban area.
2. The construction of concrete mixing station needs to consider the transportation distance and choose the convenient transportation location. The construction site selection of the concrete mixing plant not only affects the construction quality of the enterprise, but also ensures that the concrete transportation is not separated from the center, the slump loss is controlled within the prescribed range, and the production and transportation costs of the enterprise are affected.
3. The construction of concrete mixing station should choose the unequal plane, the upper layer is the sand stone material factory, the lower layer is the mixing host and the underground reservoir. The gravel is sent to the mixing tank through the conveyor belt. The construction of the mixing building with the unequal height plane can reduce the conveying distance of the sand and gravel, which is beneficial to speed up the production speed and reduce the production energy consumption. Moreover, the terrain advantage can conveniently collect the rainwater and reduce the water consumption of the production. .
4. The concrete in the production plant area should be hardened by concrete. The surrounding area, living area and office area should make full use of the unhardened open space for greening. Soundproof and dustproof equipment should be installed on the side of the factory near the residential area. The concrete mixing plant should be greened at the beginning of the station construction. It can plant double-row trees around the park, plant evergreen shrubs between the trees, plant green lawns between the forests, and plant climbing walls around the buildings. Rock climbing plants such as tigers have a good effect on reducing noise and dust. In addition, the mixing truck driving in the plant area is easy to cause dust, so the driving speed of the production volume should be controlled in the plant area, generally 5-10km/h is guaranteed.
5. The gravel yard should be closed (three walls, with hard top) installed, and an appropriate amount of rotary spray device should be installed around the material yard. The handling, unloading and loading of concrete raw materials should be closed. The gravel yard is the place where the traditional mixing station produces the most dust. The gravel unloading, stacking, handling and wind blowing can generate a lot of dust. In order to reduce dust pollution, the sand and gravel plant should be closed and installed with a rotary spray device around the material yard. The device can be oriented and quantitatively sprayed according to the humidity of the material yard and the dust of the material yard, which can not only reduce the dust of the gravel yard. Emissions can also greatly reduce noise.
