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(kuò)建工程，分部、分項(xiàng)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(yè)主提供的首級(jí)測量控制網(wǎng)點(diǎn)的基礎(chǔ)上，根據(jù)工程實(shí)際施工需要，進(jìn)一步建立工程施工測量平面控制網(wǎng)和高程控制網(wǎng)。
工程測量控制網(wǎng)在布設(shè)、施測之前需編制詳細(xì)的《工程測量控制網(wǎng)布設(shè)、施測方案》報(bào)監(jiān)理工程師審批。
4.2 工程測量微網(wǎng)的布設(shè)、施測及平差計(jì)算
4.2.1工程測量控制網(wǎng)的布設(shè)
1、工程測量控制網(wǎng)的布設(shè)依據(jù)
（1）業(yè)主提供的首級(jí)工程測量控制網(wǎng)；
（2）本工程施工平面圖；
（3）有關(guān)的工程測量規(guī)范。
2、工程測量控制網(wǎng)的布設(shè)
工程測量控制網(wǎng)根據(jù)現(xiàn)場情況布設(shè)成閉合導(dǎo)線或符合導(dǎo)線。閉合點(diǎn)或符合點(diǎn)為業(yè)主提供的首級(jí)測量控制網(wǎng)點(diǎn)。
工程測量控制網(wǎng)的點(diǎn)位布設(shè)密度以能夠滿足施工現(xiàn)場的細(xì)部放樣要求為準(zhǔn)。導(dǎo)線邊長大致相等。埋建測量標(biāo)志
導(dǎo)線網(wǎng)點(diǎn)選在通視良好、交通方便、地基穩(wěn)定且能長期保存的地方。視線要避開障礙物。對(duì)于能夠長期保存、離施工區(qū)較遠(yuǎn)的點(diǎn)要考慮到圖形結(jié)構(gòu)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
