第04章 施工測量
4.1 概述
浙江長興捷通物流有限公司碼頭擴建工程，分部、分項工程較多，在本工程的施工中，為了方便施工放樣，便于施工測量控制，擬在業主提供的首級測量控制網點的基礎上，根據工程實際施工需要，進一步建立工程施工測量平面控制網和高程控制網。
工程測量控制網在布設、施測之前需編制詳細的《工程測量控制網布設、施測方案》報監理工程師審批。
4.2 工程測量微網的布設、施測及平差計算
4.2.1工程測量控制網的布設
1、工程測量控制網的布設依據
（1）業主提供的首級工程測量控制網；
（2）本工程施工平面圖；
（3）有關的工程測量規范。
2、工程測量控制網的布設
工程測量控制網根據現場情況布設成閉合導線或符合導線。閉合點或符合點為業主提供的首級測量控制網點。
工程測量控制網的點位布設密度以能夠滿足施工現場的細部放樣要求為準。導線邊長大致相等。埋建測量標志
導線網點選在通視良好、交通方便、地基穩定且能長期保存的地方。視線要避開障礙物。對于能夠長期保存、離施工區較遠的點要考慮到圖形結構和便于加密。直接用于施工放樣的
Chapter No. 04 Construction Survey
4.1 Overview
Logistics Co., Ltd. Zhejiang Changxing Jetto terminal expansion project, division, sub-projects are more in the works, in order to facilitate the construction setting, easy to control construction survey, to be the heads of the owners based on survey control network , according to the actual construction project needs to further develop engineering construction survey control network and the elevation plane control network.
Engineering survey control network in the layout, construction survey required prior to the preparation of detailed "engineering survey control network, sampling program," reported supervising engineer for approval.
4.2 Micro-Network for Engineering Surveying, sampling and adjustment calculation
4.2.1 Engineering Survey Control Network
1, Engineering Survey Control Network based
(1) owners and the heads engineering survey control network;
(2) The construction plan;
(3) the engineering survey.
2, Engineering Survey Control Network
Engineering survey control network according to site conditions laid into a closed wire or line wire. Closed points, or conformity to the heads of the owners to provide survey control network.
Survey Control Network Spot Location density of detail to meet the construction site setting out requirements shall prevail. Traverse roughly equal. Buried survey mark established
Wire communication network chosen as a good and convenient, ground stability and can place long-term preservation. Line of sight to avoid obstacles. For the long-term preservation, distant point from the construction area, taking into account the structure and ease of graphics encryption. Construction Lofting directly
