n of plastic track

XXX track project is led by a company leader。with clear XXX.

To ensure the quality of the polyurethane plastic track surface。including smoothness。slope。and future usage。XXX is applied.

XXX XXX:

A。Request XXX。as well as physical XXX。thermal stability coefficient。volumetric n rate。water n rate。and density analysis。Check if they meet the technical quality requirements.

B。Measure the smoothness and slope of the anti-seepage concrete on-site.

For the straight ns of the plastic track。mark a point every 3 meters along the horizontal and vertical ns。For the curved ns。

mark a point every 3 meters along the radii of the circle。using a theodolite。Place a 3-meter ruler een any two adjacent points and measure the maximum local XXX of no more than 4mm is considered qualified。The pass rate for smoothness is 85%。with 85%-94% being good and ≥95% being excellent.

Measure the XXX instrument according to the design XXX.

Use the grid method to measure the height (relative) of the main track and auxiliary track。Mark the test data on the drawing and calculate the horizontal and vertical slope。The horizontal slope should not exceed 10‰。If the concrete n meets the quality standards after n。the plastic track surface XXX。XXX.

Before paving。conduct a small test on the polyurethane plastic track to be used。Sort the ponent slurry and prepolymer according to the n batch number。Then。conduct a n test and a gel drawing test according to the site's environmental ns。If a batch of slurry has a slow n rate。adjust XXX rate。If a batch of slurry fails to gel。adjust XXX process of a batch of slurry or a

barrel of slurry。stack the batch or XXX and send it back to the XXX.

Measure and draw the boundary lines on the concrete according to the XXX into ns。and pave them by n。starting from the inner circle and moving ards。XXX.

Nail the XXX。XXX.

Prepare the semi-finished products according to the required area for paving。XXX。neatly arranged according to batch number。Place the required black XXX on the operating table.

During the paving process。pay n to the control points and ns.

铺装施工过程包括配料、送料、喂料、摊铺、修边和撒颗粒等工序。在配料工序中，操作工需要按照配方将浆料、预聚体、催化剂和黑胶粒按比例计量，并经过搅拌制成合格的胶浆。如果发现配料出现错误，需要及时处理，如催化剂少加需要迅速补加，浆料和预聚体配比不符合工艺配方需要及时纠正或将错误胶浆倒掉。送料工序的任务是将合格的胶浆送至摊铺地点，

喂料工序的任务则是将胶浆推至摊铺刮尺前。摊铺工序的任务是将配制好的胶浆均匀摊铺在模腔内，操作工需要时刻检查控制厚度的标尺，若高度不符合规定需要及时调整。修边工序的任务是修整接缝边，操作工需要来回检查接缝边，若新铺胶浆液面高于已固化塑胶面或模条边需要将多余胶浆移走，若低于已固化塑胶面或模条边需要用新胶浆补足。撒胶粒工序的任务是根据胶浆固化情况及时铺撒面胶粒，操作工需要根据经验控制撒胶粒时间，如发现撒胶粒时间偏早或偏迟需要及时处理。

2.在人造草坪施工中，水泥混凝土是一项重要的工序。操

作工需要按照设计要求进行混凝土浇筑、压实和表面处理，确保水泥混凝土的平整度和强度符合要求。同时，需要注意浇筑过程中的温度、湿度和风速等环境因素，以及混凝土的配合比例和搅拌时间等技术要求。在浇筑完毕后，需要对混凝土表面进行养护，以确保其强度和平整度。

1.地基处理施工

在场地平整后，采用压路机进行地基压实处理，确保压实度不低于93%。接着进行水泥石粉稳定层摊铺，使用6%的水

泥配合不同粒径的矿粉，但必须先进行技术性能测试。水泥石粉稳定层完成后，使用C25强度等级的水泥混凝土进行浇注，
