What do you think of the general plan? What should I pay attention to when reading the general plan?

The general construction plan is referred to as the general plan for short. It is assumed that the construction site plan is a horizontal projection plan projected downward to the construction area. Then understand the general plan (2) understand the general plan and the function of the general plan. The general plan reflects the relationship between the new building and the original building in terms of plane shape, number of floors, location, elevation, orientation, surrounding roads, greening layout, topography and so on. It is an important basis for new building positioning, construction setting-out, earthwork construction and construction general layout design. The general plan mainly expresses the position and orientation of the proposed house. (3) General plan and graphic content 1. There are three ways to locate the new building: one is to locate the new building by using the distance between the new building and the original building or the road centerline; The second is to use building coordinates to determine the location of new buildings; The third is to determine the location of the new building by using geodetic coordinates. 2. Location and shape of new buildings and original buildings In the general plan, buildings are divided into five situations, namely, new buildings, original buildings, reserved areas or planned expansion buildings, demolished buildings and new underground buildings or structures. When we look at the general plan, we should distinguish between new buildings and original buildings. In the design, in order to clearly show the overall situation of the building, the number of floors in the upper right corner of the building is generally represented by dots or numbers in the general plan. 3. The terrain nearby. It is generally expressed by contour lines, from which the ups and downs of the terrain can be analyzed. 4. Roads mainly indicate the location, direction and connection with new buildings. 5. Rose chart of wind direction frequency. The wind rose chart is used to reflect the perennial dominant wind direction in the construction site and the dominant wind direction in June, July and August (indicated by dotted lines). * * * There are 16 directions. In the figure, the solid line indicates the annual wind direction frequency, and the dotted line indicates the summer (June, July and August) wind direction frequency. The direction in which the wind blows through the center of the construction area from the outside is called the wind direction. The frequency of wind direction refers to the percentage of times that the wind direction appears in a certain direction in a certain period of time. 6, trees, flowers and other green layout. 7. Layout of fountains, pavilions and sculptures. (4) Line type 1 in the general plan, new building-thick solid line 2, existing building-thin solid line 3, planned reserved land-dotted line 4, demolished building-thin solid line with cross (5) In order to be able to read the construction general plan and legend symbols in the general plan skillfully, you must be familiar with the legend symbols commonly used in the construction general plan, such as the construction general plan. (VI) Reading the general plan Take Figure 50 as an example to explain the steps of reading the general plan. (7) Basic content of general plan: (1) Drawing name and scale: Drawing name is general plan; Scale: 1: 500 (2) near terrain (contour) (roads, ditches, ponds, slopes, etc. (3) New building: The new building is drawn with thick solid lines. There are three new buildings in this painting. The new building is located in the coordinate grid; The name of the new building is student apartment building; 7 floors of the new building; (4) Original buildings: buildings drawn with thin solid lines. Such as: canteen, office building, etc. (5) Visible contours such as roads and fences, greening, compass, dimension line and pipeline layout are also drawn with thin solid lines. (6) The location or scope of adjacent original buildings and demolished buildings. Related reading: The master plan of flowing water villa presents the highest realm of nature and human survival.
