Analysis on Quality Control Methods of Hydraulic Engineering

编辑: 毕业论文 Release time: 2016-08-29 Editor: Graduation Thesis

Abstract: This article analyzes the characteristics of hydraulic engineering construction and the importance of quality control, and on this basis analyzes the methods and measures for effective control of the quality of hydraulic engineering, in order to increase the control of the quality of hydraulic engineering. Ensure that the construction of water conservancy projects benefits the country and the people, and protects the lives and property of the country and people.

Keywords: water control project quality control method strategy

I. Overview of China's water conservancy projects

1. Definition of water conservancy project and purpose of constructing water conservancy project

Definition: A project constructed to control, manage, deploy, protect, and develop surface water and groundwater in nature in order to achieve the purpose of eliminating harm and benefiting.

Purpose: Water is an indispensable precious resource for human production and life, but its state of natural existence does not fully meet human needs. Only by constructing water conservancy projects can we control the flow of water, prevent floods and floods, and adjust and distribute the amount of water to meet the needs of people's living and production for water resources.

2. Development status of water conservancy projects in China

China has a vast territory, abundant rivers, lakes, and other water resources, and possesses unique water resources. However, because China only paid attention to economic growth at the early stage of development and sacrificed environmental resources, it caused serious unreasonable and underutilized water resources. In recent years, the country has gradually realized the importance of water resources for the sustainable development of our economy and social progress, and has increased the emphasis on water resources and investment in construction. In 2009 alone, the central government invested 142.7 billion yuan in water resources facilities. . This has further promoted the development of water conservancy projects in our country, causing a large number of water conservancy projects in China to sprout, but it is worth noting that with the increase in the number of water conservancy projects, the quality problems of the projects have also become apparent, especially some For small and medium-sized water conservancy projects, how to increase the quality control of water conservancy projects, improve the project management system, and improve the quality of the project are related to the national economy and people's livelihood, the safety of the life and property of the country and the people, and also directly affect China's economic and social sustainability, Healthy and rapid development.

Second, the characteristics of hydraulic engineering construction and the importance of quality control:

In addition to large engineering volume, large investment, and long construction period, water conservancy projects also have the following characteristics:

1. Complex working conditions

The design, construction, construction, and management aspects of water conservancy projects are highly systematic and comprehensive, and problems in the construction process of water conservancy projects cannot be viewed in a decentralized and isolated manner;

① Restricted by natural conditions, construction is difficult. The construction conditions of water conservancy projects are complex and there are special requirements for the performance of hydraulic structures. Special construction methods and measures must be adopted in accordance with the technical specifications of hydraulic engineering to ensure the quality of the project;

② The benefit is great and the impact on the environment is also great. For example, after the completion of the Danjiangkou Water Conservancy Hub, on the one hand, its benefits in flood control, power generation, irrigation, shipping, and aquaculture are very significant. From October 1968 to the end of 1983, 52.4 billion KWh of electricity was generated, with an economic benefit of 3.4 billion yuan, equivalent to four times the total cost of the project. And relocation, due to changes in water quality, water temperature, and humidity, changed the microclimate of the reservoir area and changed the nearby ecological balance, etc.

③ The consequences of the accident are serious. According to statistics, although the annual rate of dam failure in the world has been lower than in the past in recent years, it is still about 0.2%. In August 1975, China's Henan Province suffered a severe flood.In addition, the Banqiao and Shimantan two reservoirs collapsed, flooding 11 million acres of farmland downstream, interrupting the Beijing-Guangzhou railway, killing 90,000 people and causing heavy losses;
