1.施工放線,根據要求結合防塵網圖紙尺寸,找出本工程相應的基礎位置,用白灰灑出準確的基礎位置。

1. Construction layout, according to the requirements, combined with the size of the dust-proof net drawing, find the corresponding foundation position of this project, and sprinkle the accurate foundation position with white ash.

2.土方開挖,基礎土方開挖采用機械開挖,人工修正挖至正負零以下2.0中間距離2m,達到設計要求,合格后再澆注C15砼墊層。

2. Earthwork excavation: Mechanical excavation is used for foundation earthwork excavation, and manual correction is carried out to a distance of 2.0 meters below plus or minus zero, meeting the design requirements. After passing the inspection, C15 concrete cushion layer is poured.

3.鋼筋制作和捆扎,所有進場鋼筋需具有產品質量合格證,鋼筋運至現場后應按批次分不同等級牌號,直徑分別持牌堆放。鋼筋的交叉點應用鐵絲扎牢,梁和柱的扎筋應于受力鋼筋垂直設置,扎筋彎鉤疊合處應沿受力鋼筋方向錯開設置。預埋件應采用固定架固定其位置,安裝符合要求以后,應于鋼筋籠點焊牢固,鋼筋籠要與模板固接,在基礎砼澆注過程中應隨時復查檢控,防止?jié)沧⒒炷習r產生位移。

3. Steel bar production and bundling. All incoming steel bars must have a product quality certificate. After the steel bars are transported to the site, they should be classified into different grades and grades according to batches, and their diameters should be stacked with different licenses. The intersection of steel bars should be firmly tied with iron wire. The tie bars of beams and columns should be set perpendicular to the load-bearing steel bars, and the overlap of the tie bar hooks should be staggered along the direction of the load-bearing steel bars. The embedded parts should be fixed in position using a fixed frame. After installation meets the requirements, they should be spot welded firmly to the steel cage. The steel cage should be firmly connected to the template. During the pouring process of the foundation concrete, it should be checked and controlled at any time to prevent displacement during pouring.

4.支護模板:基礎模板可應用木模和鋼模配合使用,在土質較好的基礎內,可直接將土壁削平作模,安裝模板前,先復查并注出地基墊層標高和中間線的位置,彈出基礎邊線,每個柱子有四塊模板拼釘而成,連接梁由三鋼模拼裝而成,模板四周要設置斜撐,是模板牢固不易變形。

4. Supporting formwork: the foundation formwork can be used in combination with wood formwork and steel formwork. In the foundation with good soil quality, the soil wall can be directly flattened as a formwork. Before installing the formwork, the elevation of the foundation cushion and the position of the middle line should be rechecked and noted, and the foundation sideline should be popped out. Each column is made of four formwork plates, and the connecting beam is made of three steel formworks. slant support should be set around the formwork, so that the formwork is firm and not easy to deform.

5.澆注混凝土:防塵網基礎承臺混凝土強度等級為C25,對其材料要求:水泥強度等級為325號,普通硅酸鹽水泥,粗骨料圍毆粒徑5-20mm的卵石,細骨料為中粗砂,含泥量小于百分之3,混凝土高度為10-30mm。

5. Pouring concrete: The strength grade of the dustproof net foundation bearing platform concrete is C25, and the material requirements are as follows: cement strength grade is 325, ordinary Portland cement, coarse aggregate is mixed with pebbles with a particle size of 5-20mm, fine aggregate is medium coarse sand, with a mud content of less than 3%, and the concrete height is 10-30mm.

6.基礎回填:撤模后,用干性粘土回填壘實。基礎混凝土強度達到設計強度的百分之93以上后,即可進行防塵網鋼結構安裝。

6. Foundation backfilling: After removing the formwork, use dry clay to backfill and compact. After the strength of the foundation concrete reaches 93% or more of the design strength, the installation of the dustproof mesh steel structure can be carried out.
