Terminology3.1 Definitions:3.1.1 Except as noted, soil related definitions are in accor-dance with Terminologies D653 and F2651.4. Significance and Use4.1 A dense, uniform, smooth and vigorously (or he

17、althy)growing natural turfgrass golf green or tee provides the idealand preferred putting or teeing surface for golf. Sand iscommonly used to construct high performance putting greenand tee rootzone systems. Sand is chosen as a primaryconstruction material due to its compaction resistance andimprove

18、d drainage and aeration compared to other soil mate-rials. A loamy soil that may provide a more stable surface andenhanced growing media compared to sand under optimal ornormal conditions will quickly compact and deteriorate incondition if used in periods of excessive soil moisture, such asduring or

19、 following a rain event. A properly constructedsand-based rootzone on the other hand will resist compactioneven during wet periods. Even when compacted, sands willretain an enhanced drainage and aeration state compared tonative soil rootzones under the same level of traffic. As such,sand-based rootz

20、ones are more conducive to providing anall-weather type of putting or teeing surface. Once compacted,sands are also easier to decompact with the use of mechanicalaeration equipment.4.2 Properties of both the soil and grass plants must beconsidered in planning, constructing, and maintaining a highqua

21、lity putting green or tee installation. Turfgrasses utilizedmust be adapted to the local growing conditions and be capableof forming a thick, dense, turf cover at the desired mowingheight. Unvegetated sand is not inherently stable and thereforeit is imperative that grasses are utilized to withstand

22、the rigorsof play. Sand does however have incredible load bearingcapacity and if a dense, uniform turf cover is maintained thesand-based system can provide a firm and uniform playingsurface.4.3 A successful sand-based rootzone system is dependentupon the proper selection of materials to use in the p

23、roject. Theproper selection of sand, organic amendments, soil, and gravelis of vital concern to the performance of the system. Thisstandard guide addresses these issues.4.3.1 During construction, consideration should be given tofactors such as the physical and chemical properties of root-zone materi

24、als, surface and internal drainage as well as stonesand other debris.4.3.2 Maintenance practices that influence playability in-clude mowing, irrigation, fertilization, and mechanical aera-tion. These factors are addressed in other standards (GuidesF2060, F2269, and F2397).4.4 Those responsible for t

25、he design, construction, or main-tenance, or a combination thereof, of golf putting greens andtees will benefit from this guide.4.5 A successful project development depends upon properplanning and upon the selection of and cooperation amongdesign and construction team members. A sand-based puttinggr

26、een/tee rootzone project design team should include a golfcourse architect/designer, an agronomist or soil scientist, orboth, and an owners design representative. Additions to theteam during the construction phase should include an ownersproject manager (often an expansion of role for the ownersdesi

27、gn representative), an owners quality control agent (oftenthe personnel that is employed in advance with the intent ofbecoming the finished projects golf course superintendent/greenskeeper), an owners testing agent (often an expansion ofroles for the projects agronomist/soil scientist) and the con-t

28、ractor.4.5.1 Planning for projects must be conducted well inadvance of the intended construction date. Often this planningrequires numerous meetings to create a calendar of events,schedule, approvals, assessments, performance criteria, qualitycontrol (QC) protocols, material sourcing, geotechnical r

29、e-ports, and construction budgets.NOTE 1Other specifications on soils for golf green and putting greenconstruction that have been published were considered during the devel-opment of this standard.5. Construction5.1 The steps involved in the construction of a new puttinggreen or tee include:(1) Surv

30、ey and stake the site to establish subgrade and finishgrade elevations,(2) Construct and prepare subgrade, subgrade being correctand certified,(3) Install subsurface drainage system,(4) Frame out putting green/tee perimeter as appropriate,(5) Install irrigation system (irrigation system may beinstal

31、led prior to rootzone installation),(6) Prepare for rootzone installation,(a) secure suitable sand, properly tested and approved,(b) blend any amendments with sand to project specifica-tions, approve using QC program,(c) install approved gravel (if included in design),(7) Install rootzone blend,(8)

32、Bring green/tee to final grade and contour as perspecifications, compact to specifications,(a) a pre-plant fertilizer application may be applied at thispoint as specified,(9) Establish turf by appropriate methods (seed, sprigs, plugsor sod),(10) Apply fertilizer as appropriate based upon soil testre

33、commendations, and(11) Turf to be established based upon grow-in recommen-dations from a competent agronomist for the turf speciesutilized and the climate of the site.5.2 Survey and StakeThis procedure should be done toconform to project Golf Course Architects specifications asF2747 102appropriate f

34、or the grade contour. When constructing a replace-ment green or tee, this step may be deleted or modified asappropriate. Care should be taken to protect staking during theconstruction process.5.3 Construct and Prepare SubgradeContour the sub-grade to specifications at a suggested tolerance of +25 mm

35、 (1in.) within 3 m (10 ft) of linear direction as specified in 5.5.7.The subgrade should be installed finished to a depth such toaccommodate the final profile depth of rootzone and a gravellayer (if included). The subgrade should be compacted suffi-ciently (suggested 85 % minimum to 90 % maximum sta

36、ndardproctor density (Test Methods D698) to prevent future set-tling. Subgrade should be designed to conform to the surfacecontour of finished putting surface.5.4 Subsurface Drainage SystemMany types of designsexist for subsurface drainage with the most common includinga grid or herringbone pattern.

37、 Most commonly used drainagesystems for sand-based putting greens and tees utilize perfo-rated drainlines with 10 cm (4 in.) diameter in a 4.5 to 6 m (15to 20 ft) spacing between drainline laterals. This spacingtypically depends upon site conditions such as height abovegroundwater, surface grading,

38、and soil type of the subgrade.5.4.1 Drainline TrenchesTrenches constructed for drain-lines should be excavated into a properly prepared, graded andcompacted subgrade. Drainage trenches should be deep enoughto conform to the drainage contours. All drainage trenches anddrainline installations should m

39、aintain a minimum positiveslope gradient of 0.5 % towards drainage outlets with trenchbottoms compacted to subgrade specifications. Drainage exca-vations should be made such that a minimum of 5 cm (2 in.) ofbedding material can be contained around the installed drain-line (below, to each side, and a

40、bove). For example, a 10 cm (4in.) diameter drainline installation will require a minimumdimension of 20 cm (8 in.) wide by 20 cm (8 in.) depth (forexample, 10 cm drainline + (5 cm/side 3 2 sides) = 20 cm; 10cm drainline+5cmtop+5cmbottom = 20 cm). Oncedrainage trenches are excavated, all excavated m

41、aterial shouldbe removed from the subgrade surface and disposed off thegreen or tee construction site. The subgrade should have noelevations of subgrade soil material such to hinder the flow ofwater along the subgrade interface into the drainage trench.Once drainage trenches have been excavated, the

42、 trenchbottoms should be sufficiently compacted to the subgradecompaction specifications prior to installation of drainagesystem. Subgrade shall be re-surveyed and certified prior togravel or rootzone import.5.4.2 Surface DrainageTo maintain adequate surfacedrainage, all green/tee installations shou

43、ld include a minimumof 0.5 % slope gradient (contours) to remove water off of theputting green/tee in case of a storm event with severe rainfallintensity.NOTE 2In planning and designing projects, consideration shall begiven to the permeability of the rootzone when determining the slope ofthe finishe

44、d surface and the need for adjacent surface drainage systems.Further consideration shall be given in cold climates where frost penetra-tion may impact the permeability of the rootzone when determining theslope of the finished surface and the need for adjacent surface drainagesystems. Generally, the

45、need for improved surface drainage increases asthe permeability of the rootzone decreases.5.4.3 Sub-Surface Drainage MaterialThree recom-mended options exist for the use of drainage material. Option1: sand rootzone material is utilized to backfill around drain-lines within the drainage trenches. Opt

46、ion 2: gravel material isutilized to backfill around drainlines in the drainage trenches.Option 3: gravel is utilized to backfill around drainlines indrainage trenches and to form a drainage layer overlying thesubgrade before placement of rootzone sand blend. Option 3 isthe method recommended by the

47、 USGA for putting greeninstallations. All backfill treatments shall be compacted tospecifications prior to further installation procedures. It isrecommended that backfill for trench bottoms is installed andcompacted prior to installing drain pipe into the trenches. It isrecommended that the trench b

48、ottom remain unobstructed andno soil pilings, wood blocks, concrete or metal blocks areutilized to permanently adjust and maintain the slope ofdrainlines. Any blocks which were temporarily used for thispurpose must be removed from underneath the drainlines andany cavities backfilled before proceedin

49、g. It is recommendedthat drainage trenches (bottom and sides ONLY) should belined with a woven geosynthetic filter fabric to preventcontamination (lateral movement of subgrade materials intotrench fill). Geosynthetic filter fabric should NOT be used tocover the drainage trench. Many geosynthetic filter fabrics areprone (or designed) to plug from fine particulates as they“filter” them from passing through the fabric. Therefore, thesefabrics should never be used to wrap a drainline, cover adrainage trench, to cover a gravel drainage layer, or to separatethe rootzone f
