what is the importance in view of safety for warehouse design
Warehouse shelves are the functions of people to be engaged in the storage of goods, according to the requirements of the storage of the environment and the establishment of storage space. The warehouse has the function of storing, adjusting supply and demand, connecting transportation, processing and distribution. The basic function of the warehouse is the storage function, which is to ensure that the material in the process of the storage of intact, so that the warehouse operations to achieve a safe and reasonable and economic. Warehouse safety is the basic requirement of warehouse management, warehouse design and warehouse security have a close relationship. Warehouse design involves a lot of content, this chapter mainly from the perspective of warehouse security to investigate the problem of warehouse design.
Because of the variety of warehouse, the warehouse design is also different, the security focus of the warehouse design is not the same. However, regardless of how the warehouse classification, the main or general warehouse and two major categories of warehouse. This chapter will discuss the design and security of the general warehouse and the warehouse respectively.
The security design of the first section general warehouse
General warehouse is a warehouse for storage of goods without special requirements. This kind of warehouse is the most widely distributed, the proportion of the largest, the use of the most common warehouse, so the research on the design and security of general warehouse has a very important significance. Warehouse safety including safety, warehouse facilities storage materials warehouse personnel safety and security aspects. In the design of the warehouse, we should ensure the safety of people, money and material from the point of safety.
Library site selection and security
Warehouse planning is to consider the distribution of the warehouse nodes in a regional scope, determine the location of the proposed warehouse. Construction of the warehouse, can not be blind to any construction must be carefully planned, repeated research for decision making do overall planning, reasonable arrangement. In this way, will not lead to the layout of the chaos, the use of inconvenience; it will not waste money, land use; will not leave a security risk. Only reasonable planning and design, in order to ensure the warehouse building in a reliable engineering geological basis, to make the warehouse has a safe, hygienic, convenient environment, to meet the storage, loading and unloading operations, such as safety requirements.
Warehouse planning requires special knowledge of two aspects of economy and technology, especially technical knowledge, if not carefully analyzed from the perspective of engineering technology, the location of the selected warehouse, hydrological, climate, topography and other natural conditions and transportation, power supply, water supply, sanitation, safety and other environmental requirements, you may leave a hidden danger to the warehouse. So the following conditions must be taken into account when choosing a warehouse address.
(a) geological conditions
Geological conditions can be used to analyze the original geological data, or the field survey to obtain the relevant information. It mainly examines whether the selected address of the foundation bearing capacity to meet the requirements, whether there is a bad geological phenomenon. If the selected address of the foundation bearing capacity is small or have bad geological phenomenon, then the construction of the warehouse is not safe. In the investigation of geological conditions, it is to analyze the nature of different strata, foundation, soil, the size of solid particles, the density of soil, water and gas in soil. The ground bearing capacity of different geological structures are selected for the foundation with high bearing capacity of the warehouse and the bearing capacity of different geological structures is 1 - 2.
Bearing capacity of different geological structures
(two) hydrological conditions
If we build in the coastal areas along the Yangtze River, we must consider all kinds of hydrological conditions, such as the heterogeneity of the flood, the annual water quantity, the variation of the flow velocity, the erosion of the bank and the deposition of the sediment. Of course, the most important factor in these factors is to consider the prevention of flood. Usually warehouse, the highest flood water level in flood frequency 0.5% ~ 1.0% (i.e. in 50 to 100 years of the worst flooding occurred when not submerged) to consider. In addition, in the construction of the warehouse should also take into account the water level, water quality, water, etc., especially the impact of the underground water level on the project, the water level is too high will not conducive to the foundation of the project.
(three) climate conditions
Temperature and humidity management is an important work of warehouse material management, which is an important measure to ensure the quality of goods. Therefore, the effect of climate condition on storage materials should be considered in the design of the warehouse.
Climate condition is a few aspects, such as solar radiation, air temperature, humidity and precipitation, and the main meteorological conditions affecting the safety of warehouse is the wind. The wind is represented by the wind direction and the wind speed of two. The direction of the wind is generally divided into 8 or 16 directions, the total number of times during a period (such as January, one quarter, one year or many years), and the total number of different directions of the wind direction in the period of the total number of times the ratio of the total number of points (that is, the wind direction). The wind is like the wind, the wind, the wind and the fire, health, etc..
(four) terrain conditions
Terrain condition is an important condition to be taken into account in warehouse planning. From the perspective of natural geography, the terrain is divided into three types: mountain, hill and plain. In a small area within the scope of the terrain can also further divided into various forms, mountain valleys, slopes, gullies, basin, Valley Road, river floodplain, terrace. In addition to the terrain in the plain area is more than a single, in the mountains or hills, often by a variety of combinations of terrain. In addition, the ground of Gao Cheng
