管涵管道安裝技術(shù)交底.doc

交底內(nèi)容：
本工程管涵位于K0+288里程處，為鋼筋混凝土管。
一、管材：
1.  本工程采用的鋼筋混凝土管必須保證可以承受6.0m覆土壓力，為平口管。
2.  鋼筋混凝土管必須在內(nèi)部熱涂瀝青一道后再安裝連接。
二、管涵基礎(chǔ)：
1.  本工程管涵基礎(chǔ)采用鋼筋混凝土管1800混凝土基礎(chǔ)，具體圖紙見(jiàn)國(guó)家建筑標(biāo)準(zhǔn)設(shè)計(jì)給水排水標(biāo)準(zhǔn)圖集（95S516，第6頁(yè)）。
2.  開(kāi)挖的溝槽人工整平后，標(biāo)高復(fù)測(cè)無(wú)誤即鋪設(shè)砂碎石墊層，整平夯實(shí)后再次復(fù)測(cè)標(biāo)高，無(wú)誤再支模澆注管涵基礎(chǔ)。
混凝土強(qiáng)度等級(jí)為≥C10，第一次澆注（管座平基）的高度為300mm，應(yīng)振搗密
Cards on the table contents:
The project culvert at K0 +288 Mileage for reinforced concrete pipe.
1, pipe:
1. This project used in reinforced concrete pipe must be guaranteed to withstand 6.0m overburden pressure, as the flat mouth tube.
2. Reinforced concrete pipe must be an internal thermal coating asphalt and then install the connection.
Second, culvert foundation:
1. This project based on reinforced concrete culvert pipe 1800 concrete foundation, concrete, see the National Building Standard Design Drawings Water Standard Atlas (95S516, p. 6).
2. Excavation trench were neat square, the level retest is correct that the laying sand gravel pads, leveling retest again after compaction level, and correct re-cast culvert foundation formwork.
Concrete strength grade ≥ C10, the first casting (pipe seat leveling) the height of 300mm, should be vibrated close
