Construction plan for lime gravel in municipal engineering projects

Safety Guarantee Measures

1. Before the start of the project, all personnel participating in the construction of the project shall be educated on production safety.

2. Adhere to no less than two hours of safety education per week. The engineer in charge will provide safety technical courses based on the construction project at that time and in conjunction with relevant norms and procedures.

3. After passing the training and examination for each type of work, you will be able to work with a certificate.

4. Operators of various types of mechanical equipment must undergo specialized safe operation technical training. Only after passing the examination can they work with a certificate. Operating under the influence of alcohol is strictly prohibited.

5. The on-site layout of production and living facilities should take flood prevention into consideration, and various preventive measures should be taken before the flood season arrives to minimize losses.

6. Set up temporary walls and guards at the construction site to prevent theft, fire and vandalism. Production safety signs, posters, and slogans are set up at the entrance to the construction site and in dangerous operating areas to remind construction workers to pay attention to production safety at any time. No one is allowed to dismantle various safety equipment, facilities, signs, etc. in the venue without authorization.

7. Regularly maintain construction access roads, strengthen maintenance and renovation, and prevent traffic accidents.

Quality Assurance Measures

1. Raw materials - Strengthen the testing of second ash raw materials. Unqualified materials will never be used in this project. The raw materials used in this project are strictly designated (banned). Materials outside the scope confirmed by testing and supervision testing) and increase the frequency of testing of the lime mixture ratio, ash dosage, and strength tests. The lime must be screened. In order to prevent the lime from cracking, the lime must be placed 7-10 times in advance. For natural digestion, the ash is screened before entering the silo, or a vibrating screen with a hole diameter of 2 cm is added to the silo.

2. Mixing - In order to prevent adjustment of the adjusted production ratio due to human factors, a dedicated person is set up in the control room of the mixing building operation station to monitor and record, and at the same time coordinate the testing and production personnel. . After discharging materials every day, the mix ratio and moisture content are detected in time, and parameters are adjusted in time if deviations occur.

3. On-site paving - detect the cross-section of the paved surface in advance, determine the paving thickness together with the owner and supervision team, detect control points based on measurement data and loose paving coefficient, and make timely adjustments if problems are found. And before paving a large area, a 200-meter test section was conducted to determine the loose paving coefficient and compaction method.

4. Rolling - Control the rolling of the roller according to the rolling method confirmed in the test section, and pressurize the edges. The rolling press of the road roller is from the side to the middle, and each round overlaps by more than 1/2 round. The curve is rolled from the inside to the outside, and the rolling method is first light and then heavy, and first slow and then fast.

5. Jointing - The processing of jointing is the focus of quality control of lime gravel. Loose parts should be removed before splicing, and the jointing surface should be formed into a vertical surface, and water should be sprinkled before paving. Wet, and strengthen the rolling of this area during the rolling process (more than four times more than the normal section. The overlapping joints are rolled using asphalt concrete lap joints to ensure the smoothness of the place.

< p>6. Health care - a dedicated person is responsible for health care to ensure that the surface of lime gravel is moist.
