Chapter 1 site measurement, accurate measurement principles is a key foundation Construction Survey smooth construction and line quality assurance, on the basis of the surface land clearing and construction units in conjunction with the track and field positioning actinomycetes, set corner posts and centrally located foundation piles, with Tongjiao pound and be protected from impact during construction shift. 2, will be a good point level has been determined on the basis of water level measurements with good elevation to the school after the introduction of the venue to coordinate point is determined as ± 0.00 relative elevation, put away the standard point, so that the whole field is level ground. Fix a playground at the construction site construction contour to facilitate construction. According to the design to control the slope of the track and field size, ensure that the basis of the width of the standard point to prevent the destruction of human factors, natural factors, to avoid unnecessary losses arise construction, provision of regular standard point retest. In order to ensure smooth drainage, must be trimmed longitudinal design requirements. All the signs are construction site set up smooth and services based on silicon pu material, so it should be protected. For some of the original control point from construction to completion and acceptance have an important role, more attention should be paid properly protected. Chapter II heavy engineering and technical measures adopted one, heavy and difficult a project, the project is 350 m outdoor track stadium, a large circular arc radius of curvature, construction survey difficult. 2, a large area of ??concrete pouring grassroots, anti-cracking, flatness and drainage slope control difficult. 3, density requires a high base course construction. Second, the response 1, the project Surveying SET500 uses a digital total station laser theodolite and a J2 100m steel tape measure, measure the formation of the three team Surveying silicon pu foaming material is not easy to ensure that accurate. 2, 12T vibratory roller compacted dense layering. 3, according to the requirements and reasonable arrangement schedule interspersed with each step, the use of network technology to control the completion of each step; the whole construction process of information management, the establishment of the duration control leading group, analyze the causes, improved construction methods to ensure successful completion. 4, in strict accordance with safety standards for civilized construction management, construction closed silicon pu material good elasticity, breathable create civilization site Runway: Features: breathable, also known as seepage runway runway, because it has good air permeability and water permeability is more rain widespread adoption area. That has the advantage of breathable runway and runway performance in general, and low cost, has become one of the plastic runway surface mainstream products. I produced the breathable runway generally used professional paver, flatness has been effectively controlled, plus upper layer using a professional spraying machine spraying polyurethane glue and high, so the surface layer and other types of runway Compared fastness relatively large, the basic need for maintenance during use, greatly reducing maintenance costs. Elastic layer breathable runway recycled scrap tires and other rubber material is pulverized into particles paving, reducing the "black pollution", and make a contribution to environmental protection. On the basis of requirements: breathable runway using cement concrete foundation to foundation requirements should have a certain strength and stability. You can not have or can produce cracks and freezing due to uneven heaving caused by the high water content still need to add cushion formations, basic needs thickening or measures taken to prevent frost heave in cold regions according to the local geological conditions. The thickness of cement concrete generally require about 120-150mm, 3 m straightedge flatness error requires no more than 3 mm silicon pu materials manufacturers, the strength required to achieve more than C20, slope surface to the outer edge inwards from the runway edge (gutter) put 6 ‰ -10 ‰ slope, it is recommended to do 8 ‰ appropriate. Cement concrete at intervals of not more than six meters to be cut sew, sew recommend 4-5 Mitch, cement concrete curing period recommended by the standard curing period of 28 days. In the case of poor flatness is prohibited to do with pure cement mortar leveling layer of skin type, it should be left to deal with when surface construction.
