C7標預應力梁張拉施工方案
根據項目辦和高駐辦要求，以及規范規定。依據景婺黃（常）C7合同段主合同、設計圖紙及相應的施工技術規范，我經理部在項目總體施工組織設計方案的基礎上，進一步認真分析，細化，編制了此預應力梁片張拉專項施工方案。
一、預制場的分布及其任務的劃分
本標段有大中小橋6座，其中主線5座，連接線1座。設置預制場3個，第一預制場設置在戴家高架橋橋頭主線路基上，該場主要負責戴家高架橋40m T梁的預制；第二預制場設置在許村中橋與許村分離中間的主線路基上，該場主要負責許村中橋與許村分離立交橋20m空心板梁的預制；第三預制場設置在婺源互通橋頭，該場主要負責董家中橋、婺源互通、張村坳中橋20m、16m空心板梁的預制。
二、預應力梁片的張拉準備
預應力梁的張拉是預制梁施工工藝流程中最為關鍵的施工工序，其工序的有效控制，是確保梁片質量的關
C7 standard prestressed beam tension construction plan
High in the project office and office requirements, and specification. According to King Wu-Huang (regular) C7 contract, the main section of the contract, the construction design drawings and the corresponding technical specifications, I am manager of the Department of General Construction in the project based on organizational design, and further careful analysis, refinement, produced a film of this prestressed beams Tension special construction plan.
First, pre-field distribution and the division of tasks
The tenders are medium and small bridges 6, in which the main line 5, the connection line 1. Set pre-market 3, the first set of prefabricated field wearing home viaduct bridge embankment on the main line, the field is mainly responsible for wearing home precast viaduct 40m T beam; second pre-market setting in the village of Xu Hui Village Bridge and the middle of the main line of separation subgrade, the field is mainly responsible for the village Xu Hui Village separation overpass bridge and 20m precast hollow slab; third pre-market set exchange in Wuyuan Bridge, the site of the bridge is mainly responsible for the Tung family, Wuyuan exchange, Zhang Village Pass the bridge 20m , 16m precast hollow plate girder.
Second, film tensioning prestressed beams prepared
Tensioning prestressed beams are precast girder construction process in the most critical process, the process of effective control is to ensure the quality of the relationship Beam of
