Chapter 1 Foundation
A, The foundation design and size
According to the IAAF relevant farmland path place designs the related request of standard manual request and the road infrastructures.
Two, The foundation drain
Adopt the turtle carry on the back type catchment, at inside of the field and runway adopts the wreath form catchment ditch, gather with the surroundings again the of water connect with each other, attaining the place catchment request.A ground of artificial lawn material and its basal catchment function requests are should be big in 180 mms/ h.
The artificial lawn place center line is gone to the slope of the on all sides side line and shoulded be small in 3 ‰s.
Three, Foundation type
The artificial lawn place can adopt the bituminous concrete foundation, the cement concrete foundation, hard quality sandy soil and native cement foundation.
Four, The foundation checks before acceptance the standard
1, Check before acceptance the request
The foundation should have the certain strength and stabilities.The foundation can't produce the crack and because of keeping the causable asymmetry jelly bulge in deep freeze.At keep the region in deep freeze, of the surface layer and the crushed stones layer should plus one layer soil work cloth buffer layer, the foundation that follows to drain the ditch should do the special watertightness processing.
Basal and neat degree:3 meters keep the Chinese foot error margin<4, horizontal, lengthways slope<3 ‰s, the runway area<4 ‰s, the surface should be flat, smooth, the assurance drain, the diameter 3 m district inside, the biggest cleft is is small in 10 mms;The diameter 0.3 ms inside, the biggest cleft is is small in 2 mms. At keep the region in deep freeze, of the surface layer and the crushed stones layer should plus one layer soil work cloth buffer layer, follow to drain the ditch and should do the special watertightness processing in the foundation.
The foundation surface at the request of keep to sweep dry, the asphalt, the concrete foundation completion of work is behind more than 30 dayses maintain the period.
2, The concrete foundation wants to use the No.20 cement, concrete height>=8 cms, the big area usage needs to consider to stay the stretch and shrink to sew.
3, The technique index sign of the bituminous concrete foundation:
After the foundation supply press the consistency solid degree>95%;The roadbed class goes together with the sand layer to press solid the solid degree of consistency amounts to the 2.3 Kgs/ kilogram above, a press a vestige depth to be no bigger than the 5 mms, the surface is neat and solid to have no sand nest, plum flower phenomenon;The consistency solid degree of the grass-roots crushed stones layer attains the 2.3 Kgs/ kilogram above, the ground gravel 2.14 Kgs/ kilogram is above, the surface is solid and going smoothly, the crevice is even, a presses to have no obvious trace;The black crushed stones layer of bituminous concrete presses solid the solid degree of consistency to attain 97% above, do the capacity to attain the 2.35 Kgs/ kilogram above, the surface has no greasy dirt, the asphalt piece that have no to did not mix blend to open, neat have no crack, have no obvious to press a vestige, have no lousy side to jostle, have no lax to face, knot to sew going smoothly, have no the phenomenon of prevent water, accumulate the water after stopping rain half an hour;The asphalt foundation should adopt not asphalt material with wax, or little contain wax, the asphalt admixture anticipates and must press solid well, the needle goes into a 1/10 mms>60, soften the point>50 ℃s, a 60 cms of extension;The anti- presses the strength R20>25 Kgs/ cm2, R50>25 Kgs/ cm2, the hot stability coefficient Kt= R20/ R50<3.5.The body rate of expansion<1%, the body absorbs water rate 6-10%.
4, Check before acceptance the procedure
Carry on according to a layer of foundation quantity standard to measure the solid quantity actually, carry on fix to the unqualified district whole;Check before acceptance the check to the data, provide from the construction unit, lawn construction the unit keeps to merge total finish construction the data;Establishment construction project;Press the engineering quantity establishment material plan quantity, beard a material arrive together the rear can start construction.
5, Tidy up on the scene
Carry on clean up towards the first floor that fix to set up lately, clearance mud, greasy dirt etc.;To the old foundation, carry on to the damaged district together the structure repair;Set up the above concrete foundation of 3 years towards fix, sew the beard to the stretch and shrink of the spot to tidy up thoroughly, stuff with the new material;To the asphalt foundation, discover the crack, should the clearance sew inside the miscellaneous articles or objects, spreading to take off one layer of the wax glass cloth after infusing the sparse asphalt, the cloth breadth is no less than the 30 cms.
Chapter 2 The first floor cloth build
A, The quantity request
The first floor cloth should have a certificate with qualified factory;The first floor cloth external appearance is neat after build, without the foundation of discover , wrinkle up the phenomenon;Build good of cloth should spread the sod to press solid in time.The first floor cloth the general doption have nonwoven cloth.
Two, Build the method
Single layer fluently to alignment, of each cloth takes to connect to be apart from the 5-10 cms.The edge orders to glue to connect the foundation on.
Three, Heavy reference of the first floor cloth gram( press grass high, the place type, the foundation type dissimilarity distinction)
The grass is high Have no cloth specification of Place type Have no cloth specification of nonwoven cloth Foundation type
20mm 120g~150g A ground 120g~150g Asphalt
20mm 120g~150g A ground 120g~150g Concrete

Chapter 3 The artificial lawn build
A, Construction preparation
The lawn ships to the construction the spot, according to build the diagram to prepare lawn spreads to open, the confirmation quantity, color of the lawn, make sure that the grass silk pour to for same direction, relatedly to assist to anticipate, construction equipments and tool, confirming construction temperature should keep are above with 10 ℃s.
Two, The diagraph puts the line
Design the position that the diagram paper marks each side of place line and lineses presently and up according to the place, the marking should know definitely.
Three, Construction
1, Will glue to connect to take to follow the lines marking to glue to connect the first floor cloth on.
2, Following artificial lawn lines the lines marking glues to connect to glue to connect to take on, insure it neat and firm.
3, Carry on slicing the side to the artificial lawn with the appropriation tool, put together to connect, put together to sew to be apart from should<2 mms.
4, Put together to sew to carry on glue to connect to the lawn, the lawn puts together to sew of all apply to glue to connect to take to glue to connect.
5, Put together to sew to carry on press solid to the lawn, insure to put together to sew neat and firm.
