The title of my speech is: study and implement the partys two laws, doing practical play highway. 2015 October 18, the Central Committee of the Communist Party of China promulgated the implementation of the and Chinese Communist Party discipline and punishment regulations. We Heyuan male passers-by to respond positively to the call of the Central Committee of the party, earnestly organize the study party two regulations, truly grasp the essence and gist, and in their respective positions, to hold the bottom line of the discipline, build a strong ideological line of defense, with the courage to play, the courage to fight tough and fearless spirit, at the crucial moment well to complete the task, with practical action to test the study and implement effect Because of discipline in the * * * * * * * * * * * story. Here, let me to cast a brick to attract jade, speak about our highway. Highway line section of the road surface transformation project, last year towards the country seized will be seized one of the items. To complete this arduous task, as a project management office director Comrade, keep in mind from the Communist Party membership, recognize and identify the bottom line, strict management, and strict adherence to the quality of the project. He not only set an example, honesty and self-discipline, but also requires the management of all the members of the O.K., do not eat the construction unit one meal, do not accept the construction unit a ceremony. In this way, they didnt really dare to adhere to the principle. No comrade, constantly put on reworking an emergency meeting to Comrade Zhen to speak louder, management tube too strict. Remember in Dongguan Street, 400 meters long cement concrete surface layer, because of various reasons, the smoothness of the poor in the bottom cavity, covering film traces and car imprinting quality problems, * * * inquiries, immediately rushed to the scene to understand and verify the situation, the convening of the management office, the construction units, supervision units, construction units, construction units construction time is tight, the economic loss and other reasons to intercede * unmoved. He said, now a popular word, to the discipline and rules quite in front, there are no rules Radius, you construction team not accordance with the technical specifications, quality problems, it must be to carry out rectification. Engineering quality responsibility be weightier than Mount Tai, if we manage to this matterPavement quality quantity are placed the matter, we this time to learn two regulations have what use? Still what is the Communist Party? Finally, in his insisted, the road after rework, to solve these problems. In the construction of the new comrades and the project all the colleagues efforts, after four months of fighting, the project the main project was finally completed and passed inspection. Thousands of miles of ice, thousands of miles Piao, this is a splendid and romantic scene. But snow for the highway, it is a disaster, a serious threat to the traffic safety. This year, a month, a century of cold wave swept from North to south, and the snow blowing to Guangdong, but also to bear the blow To * * * * the highway. In January on the evening of 23, Lianping county city temperatures dropped to minus 2 degrees, a wide range of sudden rain sleet, before and after the provincial S341 line in Jiulianshan Mountain tunnel sections of the road appeared in the snow, lead to the passing vehicles skid, traffic is blocked. In the face of the sudden natural disasters, city and county highway department immediately launched the emergency plan for disaster prevention. As the front line of the main force, Lianping Highway Bureau of all Party members and cadres to remember the Party member responsibility, braving the biting cold wind, the first time rushed to the scene, on the icy pavement of salt disposal. Because the temperature is too low, just melt water immediately freezes, addition to the ice work to increase the difficulty. To ensure In addition to the re organization of the depths of the traffic safety, road people braved the icy put reflective cones and warning signs, endure cold at minus 2,3 of Jiulianshan patrols until one in the morning. Just before dawn, Lianping Highway Bureau personnel on the icy road salt ice melting processing until ten oclock, ice melting ice success, the road gradually returned to normal traffic. In the cold winter night, which people do not miss the warm bed, which people do not miss the warm home. However, our highway on the road to the owners of the masses can go home early, the night fighting to secure the avoidance of the road safety and smoothness, fulfill their responsibility. Xi General Secretary Every Party member cadre cautioned against said: blacksmith needs self hard . two regulations , is our own hard standard test, more exercise every party members and cadres of the fire. We should continue to strengthen the party two regulations, conscientiously in practical work, practical play road, the road for the development of the cause of Heyuan and struggle.In the industry domain report the situation of road traffic in recent years, in the province highway departments of the concern and support, our bureau management department based on the job, loyalty duty, best service, to further promote the highway management standardization, legal, scientific and information technology to improve the management level and service quality. This will be my last work is as follows: first, around the center, go all out to greet the seizure in 2015, meet national examination is my bureau work. As the highway management department, we focus on the work of the center to strengthen road renovation and management as the focal
