According to the National Highway Law of People's Republic of China (PRC), the Regulations on Highway Management of People's Republic of China (PRC), the Regulations on Highway Management of Anhui Province and the Administrative Licensing Law of People's Republic of China (PRC), this plan is formulated in combination with the actual situation in China.
2 overview
Performance of 10 contract in Jixi county, Xuancheng city, Anhui province and town section of Liaoning province of Nanjing Expressway. ZK39 276.576 for the design mileage of the left lane? ZK43 709.068 Right line mileage K39 +270 to K43 +7 10. The Ministry of Education plans to build a service road at the intersection of S323 line group to ensure safety and efficiency. In this way, S323 line K3 +650 K3 +950 and S2 15 line K 147 +000 and K3 +720 cross into the project department, and the four-in-one * *.
3。 Construction method
3. 1。 According to the design drawings, accurately design the survey category of sidewalk junction with widths of 6m,10m and10m.
3.2。 The shoulder is replaced with 30 cm gravel as cushion, then rolled, and the top surface of C20 concrete is poured with a thickness of 20cm. Clean the concrete surface of asphalt pavement.
3.3。 Fill the top of culvert with 50 cm gravel, and then roll it. C20 concrete with a thickness of 20cm is poured on the top surface.
3.4。 During the construction process, full-time security personnel were set up at each intersection. The sidewalk is responsible for directing vehicles of historic buildings to ensure the safety, cleaning up vehicles at intersections and construction vehicles, and ensuring roads with muddy construction vehicles.
3.5。 Mark the exact positions on both sides of10m grade crossing on the sidewalk.
3.6。 Fences shall be set on both sides of the exact location of the construction road in grade crossing with safe sidewalks. At the intersection within 50m on both sides of the construction road, about every piece of the S323 provincial road S2 15 is painted with deceleration zones, and the sidewalk intersection is 200m away from the deceleration warning signs.
4。 Quality, safety and environmental protection measures
4. 1。 Organization's engineering quality assurance measures
(1) Ensure that
The quality of the project management team established by the project is led by the project manager, who is fully responsible for the quality responsibility of the project leader. There is a full-time quality engineer, the quality inspection department under the project department, a full-time quality engineer under the professional project department and a quality control engineer under the project team. The working class set up quality inspectors to control the whole process of project implementation.
(2) System guarantee
① The project has established a perfect lifelong responsibility system for quality.
Implement the lifelong responsibility system for project quality. Quality lifelong responsibility book, signed by competent leaders at all levels, to ensure that all quality-related quality responsibilities can be traced back, to clarify the highly responsible attitude between departments on work quality and personnel quality, to ensure their work quality and work quality, and to ensure a virtuous circle of various systems and field operations. Validity and authority
(2) Ensure that quality inspection engineers supervise the project department to set up full-time quality inspection engineers, and the project department will be institutionalized. The effectiveness of quality inspection and supervision of project management ensures the on-site quality control engineer, who is the incentive institution to manage project implementation. Working experience in the project department, for all kinds of valuation, must be signed by quality inspection engineer, pre-measurement plan, project management department approval and financial payment. Valuation system
(3) establish a quality assurance fund, from the cost of each project department to achieve high-quality products at a higher price, and set aside 2% for quality assurance, check the valuation fund, professional engineering team, higher price, and better implement the quality system. According to the quality of engineering and technical team, the pricing method of quality incentive coefficient of responsibility budget is implemented. The chief engineer and project manager of the quality incentive project shall be submitted to the quality control engineer for approval.
④
The goal of safe production is to establish and improve the quality inspection and certification system: six elimination, two control and one innovation.
VI elimination: eliminate the accident of the last worker who died obviously due to work or non-work, eliminate the accident in multiplayer games, prevent the occurrence of major mechanical equipment accidents, eliminate traffic accidents, cause our responsibilities, and prevent major floods and fire accidents; stop
The second control: in recent years, the serious injury rate is controlled below 0.5%, and the annual injury rate of crisis explosive explosion accidents is controlled below 0.5%.
Elimination: Eliminate illegal command, illegal operation and inertia accidents. 6%。
Create:
Establish a safety assurance system, led by the project department, and firmly establish the guiding principle of "safety first, prevention first, comprehensive management" so that everyone can have a safe website. The characteristics of safety and development, the safety measures of this project are as follows:
(1) Establish a safety leading group.
Person in charge:
Deputy Team Leader Xu Jing (Project Manager), Chu Jingjie (Assistant Manager) and Minister of Safety: Wang Wenting ().
: Fu Binkui Wang Yongli Li Fen Jiang Wei Zuo Wei
() Development safety
Strictly implement construction measures; And from the actual situation of technology, solve the safety problems in construction in time and realize the safety goal.
(1) During the construction, strictly implement:
(2) The construction and installation of temporary power lines on the construction site, the safety technical regulations and safety technical operating rules for construction and installation workers, and the installation and use of power transformation and distribution facilities conform to the requirements of Technical Specification for Temporary Power Use in Building Construction (JGJ46-88) issued by the Ministry of Construction, as well as the idea of power line construction organization design. Do not pull cables indiscriminately or connect them randomly.
(3) Construction machinery, according to the specified location, this method may infringe on the installation of provincial highway 323, S2 15 pavement construction machinery, and put it into use after passing the safety inspection. Special operations personnel's
(4) The website GB5036-85 "Provisions on Safety Technical Assessment of Special Operators" special post training and assessment certificate.
4.2。 Environmental protection and civilized construction measures
(1) Environmental protection measures at the construction site
(1) Strive to requisition farmland within the scope that the owner may occupy less or fail to act.
(2) The construction site and garbage disposal on the construction site, environmental protection, residents' reaction to the quality of the construction team, centralized stacking of production garbage and timely treatment. avoid
(3) The sewage in the sewage pool will be discharged up to the standard after precipitation, which will not pollute the nearby water system. In the orderly work, the construction site is civilized and environmentally friendly, which fully embodies the excellent architecture and environmental protection of modern civilization.
(4) Pay attention to the excavation. If there is an underground pipeline, if you contact the owner and relevant departments in time and solve the problem reasonably, instead of blindly doing it, if you accidentally encounter the underground pipeline, report it in time to protect the site. succedent
(5) After the sidewalk construction is completed, water should be sprinkled on the construction road every day to ensure that it is moist and does not accumulate dust.
(2) Civilized construction
(1) Establish civilized construction organization and formulate specific measures to keep the site and living area clean and tidy.
(2) Safety warning signs, protective piles and speed-limiting facilities are mainly set on the construction roads to reduce personnel, and outsiders are not allowed to enter.
