1. 1: Establish the construction supervision department, keep the construction materials and equipment, supervise the work efficiency of the construction personnel, and propose reasonable solutions to the problems in the construction process.

1.2 Make a good construction technology plan.

2. Surface structure link

arrange

2. 1: Before manual paving, check whether the formwork is installed in place and the dimensions are up to standard.

2.2: After the cement concrete is poured into the formwork, it is properly tamped, so that the slurry in the concrete is completely discharged from the concrete, effectively avoiding the phenomenon of hollow honeycomb.

2.3: The paving height is slightly higher than the design template 10%, because the concrete will shrink.

shake

2.4. Vibrating is a complicated construction technology, which requires experienced masters. The final standard of vibro-compaction in construction is: "concrete will not sink to the bottom after mixing, there will be no bubbles on the surface, and there will be no floating mud on the concrete surface".

Pulp extraction

2.5: In order to make the road surface smoother, slurry lifting should be carried out.

Cleaning and plastering

2.6: In the process of plastering, the flatness should be constantly checked, and embossing should be carried out after plastering. Remember to have a certain slope when closing the slope.

decorate

2.7: When there is no slurry on the surface of cement concrete, it is most appropriate to press it with your fingers to feel hard. The pulp is pressed in the early stage, and the grain is not deep enough in the later stage.

Health maintenance

2.8: Cover the sacks and water them regularly. After the strength reaches 80%, there is no need to maintain health.

lancing

2.9: When curing induration, cut to the thickness of 1/3. After the maintenance, clean up the sundries on the pavement, fill the joints, and then pour the asphalt into the cracks. At low temperature, the poured asphalt is lower than the pavement, and at high temperature, the poured asphalt is higher than the pavement.

Construction preparation work

1, organization establishment

According to the project scale and progress, the project commander-in-chief will convene all personnel in time to discuss the formation of the construction organization. The specific personnel organization is as follows:

(1), establish on-site organization.

Responsible for the overall coordination of the project site.

(2), set up a full-time quality inspection team.

Responsible for the quality inspection of the project site.

(3), set up a safety inspection team

Responsible for safety production and traffic guidance on the construction site.

(4), set up a professional construction team

Responsible for road laying and kerb installation.

(5), the establishment of civilized production team.

Responsible for on-site civilized production and project finishing work.

The above groups shall be the responsibility of the designated personnel, and the responsibility shall be implemented to the people.

2. Technical preparation

After receiving the engineering drawings, the project leader and technical leader shall promptly organize relevant personnel to study the engineering drawings, conduct on-site investigation, prepare the construction organization design, and make detailed technical disclosure.

3, mechanical equipment preparation

Combined with the characteristics of this project; The following machinery shall be organized during construction:

① Cutting machine: 2 sets.

② Loader: 1 set.

③ Roller: 1 set.

④ Impact rammer: 2 sets.

⑤ Mixer: 1.

⑥ Dump trucks: 2 sets.

All landowners, according to the need to configure the dump truck.

4, material preparation

The main materials of this project (kerbs, square bricks, reinforced concrete pipes, concrete, red bricks, sand and cement) will be supplied in time with good quality and quantity according to the construction progress to ensure the smooth construction of the project.

5, the construction site preparation

After detailed investigation on the site, according to the actual situation on the site, the road has been unblocked, the site has been leveled, and temporary water and electricity for construction will be introduced from the place designated by Party A. The construction party shall conduct on-site setting-out survey according to the engineering drawings.

(2), construction process control

1, control principle

In order to make the project achieve the specified quality objectives, it is necessary to comprehensively and effectively control all the elements in the whole construction process, with the emphasis on the construction process of key processes.

2, the construction process control requirements

On the basis of self-inspection and mutual inspection by the construction team, each working procedure of the project can only be handed over after special inspection by the inspector, and the construction of the next working procedure can not be carried out without inspection in the previous working procedure.

3. General process control

(1), the project leader shall be equipped with all kinds of professionals according to the requirements of the construction plan, and all professionals shall hold relevant certificates.

2, organized by the technical director of construction management personnel, the first-line team for engineering technical disclosure.

(3) According to the construction schedule, the materials engineer will prepare the necessary materials and equipment at the site to ensure the normal construction of the project.

(4) Safety measures shall be formulated by the safety officer, and necessary training shall be given to employees to ensure safe production and civilized construction.

4, construction process inspection and test control

(1), incoming inspection and test

(1), raw materials, components (parts) and engineering equipment entering the site shall be put into storage for acceptance, and the material engineer shall arrange full-time personnel to verify and review their quality documents, and mark various products on the site.

(2) All raw materials, components (parts) entering the site shall be inspected and tested by the construction department (including sampling inspection), and an application for material inspection shall be made to the supervision engineer.

(3), all materials that must have a product quality certificate, in the absence of product quality certificate and inspection certificate, it is strictly prohibited to issue.
