2. On-site investigation of construction projects (surrounding roads and traffic conditions, existing buildings, water and electricity connections, on-site drainage outlets, construction areas and entrance and exit settings of fences, etc.). ).
3, the general situation of the construction project, construction scheme, construction progress plan, in order to understand the situation of each construction stage, reasonable planning of construction site.
4, all kinds of building materials, components, processed products, construction machinery and transportation list (including needs
Information such as quantity and overall dimensions), so as to plan the storage location and transportation route in the construction site.
5, component processing plant scale, warehouse and other temporary facilities demand quantity and specifications.
6. Technical Specification for Fire Safety in Construction Sites (GB 50720-20 1 1),
Technical specification for temporary buildings in JGJ construction site /T 188-2009.
7, the local authorities and the relevant provisions of the construction unit on the construction site safety and civilized construction, the construction unit safety and civilized construction standards.
Content of general layout of construction
1. Draw the proposed building (structure) and determine the construction site area.
2. Set fences, entrances and exits, and introduce off-site traffic roads; The construction site area is divided into site office area, temporary living area and site production area.
3. Site production area layout (different layout requirements will be different in the construction stage, taking the superstructure construction as an example):
(1) Layout of main machinery and equipment (tower crane layout should be considered first, then construction elevator layout should be considered, and concrete pumps and other machinery should be arranged after the internal transportation roads are arranged).
(2) Layout of internal transportation roads.
(3) Arrange the processing plant and mixing station (consider the steel bar processing plant first).
(4) Arrange temporary facilities (warehouse, steel shed, woodwork shed, guard, reservoir, car wash pool, etc.) in the production area. ).
(5) yard for materials, semi-finished products and components.
4. Layout of on-site office area and temporary living area. -If the site is small, and the site office area and temporary living area are rented or designated by Party A, a floor plan is attached.
5. Arrange temporary water and electricity pipe network and drainage system.
6. Necessary legends, descriptions and labels, compasses, etc.
Construction site plan's Drawing Methods and Skills
1, drawn in stages
Taking the general contracting project of housing construction as an example, it is suggested to arrange it in the following stages:
(1) earthwork excavation and support stage of foundation pit: at this stage, the production area will draw foundation pit sideline, foundation pit ramp, transportation channel, foundation pit drainage ditch and grit chamber in the foundation pit, and the entrance and exit will be provided with car wash tanks.
(2) Basement construction stage: At this stage, the production area should draw the foundation pit sideline, and draw the basement structure and the outer edge of the post-pouring belt. The layout of tower crane should meet the requirements of superstructure construction.
(3) Superstructure construction stage: At this stage, the outer contour line of the basement in the production area can be drawn as a dotted line, and the layout of the processing plant is different from that in the basement construction stage. Some processing plants can be moved to the basement roof, which can increase the layout of construction elevators, masonry material yards and installation sites.
(4) Decoration and installation construction stage: at this stage, it is necessary to replace the steel bar processing plant, formwork processing plant and scaffold material yard required for structural construction in the production area, and increase the decoration construction site and installation site layout.
(5) Outdoor engineering construction stage: At this stage, the processing yard and material yard are basically replaced, and the influential office area and temporary living area should also be replaced. At this stage, residential roads and
The outdoor landscape structure is painted.
2. Layout of tower crane
The plane position of tower crane mainly depends on the plane shape of the building and the surrounding site conditions.
Generally arranged at the edge of buildings, high-rise buildings must be reinforced with walls, and the distance from the walls is about 5 meters;
The service radius of tower crane should basically cover high-rise buildings;
If there are prefabricated members or steel structures for hoisting, check the hoisting capacity of tower crane (most
Long distance, heaviest component);
The arrangement of group towers should avoid each other, but the coverage should overlap a little; hammer-head crane
The layout should also consider the convenience of disassembly.
3. Transportation road layout
(1) Use the original road as much as possible;
(2) Meet the requirements of fire control, with a width of not less than 4m; If the construction site is relatively loose, two lanes can be set up; if the site is relatively narrow, a single lane, preferably circular, or a return yard can be set up;
(3) The transportation channel should reach the main processing plant and the construction elevator from the municipal road as far as possible.
4. Arrange construction elevators, concrete pumps and other machinery.
When arranging the construction elevator, you should check the standard floor plane of the tower and try to set it on the balcony.
The concrete delivery pump should be as close to the inlet and outlet as possible.
5, determine the location of steel processing plant, mixing station, processing shed and material and component yard; Should be as close as possible to the place of use or within the capacity of the crane, and can not affect the transportation channel.
