交底内容：
1. 本工程包含的预埋件种类：
综合管沟预埋件主要为预埋钢板、预埋钢管、预埋吊环及爬梯等。在标准断面的电缆仓、水仓和通信仓内的侧墙、底板和顶板均须预埋钢板，防火门两侧各埋设一块500×100×10钢板；电缆仓和通信仓的顶板底、底板顶须预埋吊环，另在非标准断面、综合管沟交叉口及各种接出口附近均布置有预埋件。预埋件的具体布置详见相关的设计图纸。
2. 预埋件的制作：
预埋钢板制作安排在公司车间进行，按照设计图纸规格在车床加工钢板，根据需用数量将加工好的钢板运至施工现场。根据设计图纸，规格为250×150×10的钢板设两排锚筋，每排3Φ14，锚筋间距为75.0mm，排距为50.0mm。规格为500×100×10的钢板设一排锚筋，锚筋间距为100mm；锚筋与钢板采用T形焊。
预埋Φ22钢筋吊环安排在现场钢筋加工场制作，按照设计图纸进行下料、加工，制作完成后有序堆放在钢筋棚内，并要注意防锈。
爬梯根据设计图纸要求，若是包塑防腐爬梯，向厂家订做，一般爬梯则安排在现场钢筋加工场制作。
3. 预埋件的安装：
(1).  测量定位：根据设计图纸，按照预埋件的分布及间距在现场进行测量放线定位，并做好预埋定位点标记。
(2).  安装顺序：底板、侧墙预埋钢板要在其钢筋绑扎完成后进行；顶板预埋钢板及吊环要在模板安装完成及绑扎钢筋前进行。
(3).  固定措施：采用点焊的方法固定预埋件，固定时注意：
预埋件定位经复核无误后，将锚固钢筋与综合管沟结构钢

1. This project contains embedded parts Category:
Combined duct embedded parts mainly for embedded steel, embedded pipes, rings and Ladders and so embedded. Section of the cable in the standard warehouse, water storage and communications positions within the side walls, floor and roof must be embedded steel, fire doors on both sides laying a 500 × 100 × 10 steel; cable storage and communications positions in the roof bottom, bottom Top to be embedded rings, the other section in the non-standard, integrated trench intersection and then exits are all embedded parts are arranged. See the specific arrangement of embedded parts related to the design drawings.
2. Embedded parts of the production:
Embedded steel making arrangements to conduct workshops in the company, in accordance with the design drawings specifications sheet in the lathe, the number will be processed according to Xu Yong steel shipped to the construction site. According to design drawings, specifications for the 250 × 150 × 10 set up two rows of steel anchor bars, each row 3Φ14, Anchorage spacing of 75.0mm, row distance of 50.0mm. Specifications for the 500 × 100 × 10 steel plates set up a row of Anchorage, Anchorage spacing of 100mm; anchor bars welded with steel plate with T-shaped.
Φ22 steel rings embedded steel processing arrangements made in the field, in accordance with the design drawings for cutting, processing, production of complete and orderly stacked steel shed, and to rust.
Ladder according to the design drawings, if coated corrosion ladder, customized to the manufacturers, the general ladder is scheduled for processing in the steel production site.
3. Embedded parts of the installation:
(1). Measurement Location: According to design drawings, in accordance with the embedded parts of the distribution and spacing were measured in the field-off position and do a good job embedded anchor tags.
(2). Installation order: bottom, side walls embedded in the steel plate after completion of banding; roof plate and rings embedded in the template installation is complete and the steel banding before.
(3). Fixed measures: use of spot-welding method of fixed embedded parts, fixed attention:
After review and correct positioning embedded parts, will be integrated trench anchor bars and structural steel
