museum Outdoor works Construction organization design
The project site is 206m long, 112m wide and covers an area of 23072 ㎡. After subtracting about 3400 ㎡ occupied by buildings, the actual outdoor project occupies about 19672 ㎡, covers about 4.5m × 732m of roads, which is about 3294 ㎡, about 2500 ㎡ of lawn tiles, about 4000 ㎡ of granite floor, about 900 ㎡ of square tiles, about 1000 ㎡ of two pools (including 201 ㎡ of round pools), and the rest is about 6978 ㎡ of green land, The bluestone floor is 800 ㎡, and a small amount of shale slabs and pebbles are added. The fence is about 600m long, and there are two electrically controlled entrance and exit gates. Since the drawing of this project is a landscape control drawing, its practice is incomplete, so it is recommended to construct according to the following requirements. 1. The road is 4.5m wide, and the method is as follows: the base course is compacted three times, 250 thick hand laid rubble is compacted three times, the road roller is compacted three times, 50 thick gravel leveling layer, 200 thick C30 concrete (see Figure I), and the turning radius of all turns and T-junctions is 8m. The longitudinal gradient of the road is 0.5%, with an expansion joint every 12m and a contraction joint every 4m (see Figure 2). 2. Practice of granite, bluestone slab and square brick The site shall be compacted for three times, 100 thick C20 concrete cushion shall be poured, and the surface course shall be pasted with 1:2 cement mortar. The total thickness of the surface course is 50, and the thickness of the plate shall be 18-20mm. See the landscape map for details. 3. Lawn tile After the site excavation, it shall be compacted for three times, paved with 200 thick graded sand and stone, and paved with 70-100 thick lawn bricks. 4. Greening area Take 300 thick soil layer of the existing site and transport it out of the site. Fill 300 thick planting soil. After the greening design scheme is out, confirm the planting variety and model selection. The large green area and the square are separated by curbs. The independent trees are built with 240 thick bricks, with an inner diameter of ≥ 1000 and a height of 300. The surface is covered with opalescent tiles (100 × 100 exterior wall porcelain plates), and the seam width is 10mm. 5. Pool The bottom and wall of the pool are reinforced concrete, concrete C30, and the reinforcement is double-layer and two-way ζ 12@200 , the reinforcement φ 8 @ 400 in the wall plate is arranged in quincunx shape (the base plate horse stool is 12@1000 Plum shaped layout), the waterproof material is 4-thick SBS waterproof coiled material, and other practices are the same as the original drawing. The surface layer is covered with milky white 100 × 100 ceramic tiles (closely laid).
