水利施工组织毕业设计

摘 要

施工导流是保护水利水电工程在干涸河床正常施工，控制河水下泄所采取的工程措施。施工导流设计是水利水电枢纽总体设计的重要组成部分，是影响坝址选择、枢纽布置、永久建筑物型式、施工程序和施工进度的重要因素。

本设计依据《水利水电工程施工组织设计规范》（SDJ338-89）第二章施工导流的有关规定编写。在对坝址区域的地形、地质资料，水文气象资料分析的基础上通过对堰型、隧洞型的定性分析比较，定出隧洞轴线、堰轴线的位置。由于坝址附近有丰富的料场，并且距坝址较近，交通运输较方便等，综合考虑最终拟建上游为土石坝围堰、下游为土石坝围堰。

该工程主要由上下游围堰、导流隧洞等组成。设计确定上游围堰的堰顶高程为450.50m，堰顶宽为5.00m，堰高为40.50m，下游围堰的堰顶高程为427.00m，堰顶宽为3.00m，堰高为17.00m，隧洞底高程为418.00m，隧洞宽为15.00m，隧洞高17.500m，隧洞坡降为0.001，进口长为50.00m，洞身长为500.00m，出口长为50.00m，并采用扩散消能。

设计最终成果：说明书一份、计算书一份、设计图纸4张及其他计算附图和附表等。

Abstract

The construction diversion is protect water conservancy water electrician the distance be normal to start construction in the dried up river bed, control the engineering measure adopted for leaking river underwater. Construction diversion a design is the importance of water conservancy water electricity vital point total design to constitute part, is influence the dam address choice, vital point decoration, permanent building pattern and start construction the important factor of procedure and construction progress.

This design leads to flow according to 《water conservancy water electrician distance construction organization design norm (SDJ338-89)》 chapter 2 construction of relevant stipulate to write. It is passing the qualitative analysis comparison to the embankment type, tunnel type in the foundation of hydrology weather data analysis to the geography, geology data of the dam address district; settle the position of the tunnel stalk line, cofferdam stalk line. Because the dam address neighborhood abundantly anticipated a field, and was nearer apart from the dam address, transportation more convenient etc., synthesize to consider to finally draw up to set up the upper stream rounds for the concrete cofferdam, downstream to round an Straw-soil cofferdam.

The engineering is mainly visited by top and bottom to round a cofferdam and lead to flow tunnel etc. to constitute. Designing makes sure that the upper stream rounds the crest of cofferdam for the 450.50 ms; cofferdam crest breadth is 5.00 ms, and the cofferdam is 40.50 ms high. The downstream rounds the cofferdam crest engineering is 427.00 ms, cofferdam crest breadth is 3.00 ms, cofferdam is 17.00 ms high. Tunnel bottom Gao Cheng is 418.00 ms, with 15.00 ms wide and 17.50 ms high, the Tunnel ascent declines to 0.001, import is 50.00 ms long, the hole height is a 500.00 ms, export long is 50.00 ms, and adopt to spread to eliminate ability.

The achievements of the design are as follows: directions of the design calculations of the design and with 4 engineering drawings of the design as well as other schedule attached etc...
