地坪綠地坪工程中，大部分都使用混凝土作為基礎，而混凝土基礎存在這一個人力無法改變的因素，就是混凝土會根據環境溫度進行熱脹冷縮，所以混凝土澆筑后必須切割有伸縮縫作為混凝土自身熱漲冷縮的緩沖空間;除了伸縮縫之外還有地坪施工中止的合道縫，也會根據溫度進行伸縮。由于我們施工的地坪綠產品是覆蓋在混凝土之上的，如果伸縮縫合道縫之類的沒有進行處理，在混凝土進行熱脹冷縮運動的時候，就會很容易地將地坪表面拉裂;為了延緩地坪被拉裂，保證地坪綠產品的使用質量，在做基礎處理的時候，必須按照本規程處理伸縮縫。
一、伸縮縫處理的作用
1、延緩混凝土基礎熱脹冷縮運動時將地坪表面拉裂的時間，減少地坪被拉裂的概率;
2、盡可能的保證地坪整體、美觀。
二、需要處理伸縮縫的地坪種類
1、環氧地坪
2、壓克力球場地坪
3、硅PU球場
4、其他地面(地坪)系統
三、基礎切割工具
常見地面伸縮縫處理機械設備：
品名 使用電壓 適用范圍
馬路切割機 380V 大面積切割
角向磨光機 220V 伸縮縫斜度研磨
手提式切割機 220V 不規則裂縫切割與小面積切割
四、打磨準備
1、檢查所有的連接電線是否存在破損、串聯等現象，發現破損或者短路必須馬上修復或者更換，不得勉強接駁電線;
2、檢查打磨使用的機械，接駁電線后是否能夠正常運轉、零件是否松動或缺失;
3、穿戴好勞保用品，將需要保護的設備用薄膜或者彩條布進行覆蓋，避免污染;
4、原基礎如果還沒有切割伸縮縫的，需用墨斗彈線后再進行切割，切割必須形成直線;
5、根據機器的使用電壓接駁電線，電線接駁時，應選擇在電源穩定且安全的配電箱進行接駁;電源線源頭應該先固定起來再接駁，避免在切割過程中出現拉扯將電線扯掉形成短路。
五、切割程序
1、大面積切割需先根據設計彈好墨斗線，沿著墨斗線直線切割，需注意切割機水箱的水量，水量低過一半需及時加水;
2、大切割機切割完以后，將泥漿全部清理干凈，然后用角向磨光機將伸縮縫兩邊斜向研磨成45°，兩邊相距寬度不得少于1㎝;
3、不規則的龜裂縫，需用手提式切割機順著裂縫切割至少2㎝深，并且同樣使用角向磨光機將兩邊研磨成斜45°，寬度不得少于1㎝。
六、衛生清理
1、清理衛生，可選用吸塵器或者大掃把，隨身需配備毛刷和勾縫用的器具，清理時必須將伸縮縫內的泥漿和灰塵清理干凈。
Ping Ping green projects, most of them use concrete as a base, and the presence of this human element can not be changed concrete foundation is the concrete will be conducted according to the ambient temperature thermal expansion and contraction, expansion joints must be cut so as concrete pouring concrete self-heating or cooling of buffer space; in addition there are expansion joints Floor construction suspended Hop Road seam will be scaled according to the temperature. Because of our construction floor green product is overlaid on top of the concrete, if the co-channel seam joints like no treatment, thermal expansion and contraction movement in concrete and they will easily crack the floor surface ; to delay floor pulled crack, ensure the use of quality floor green products in the foundation process, he must deal with the expansion joints in accordance with these regulations.
First, the expansion joint treatment effect
1, the motion will delay the expansion and contraction of the concrete foundation floor surface crack of time, reducing the probability of crack in the floor pulled;
2, as far as possible to ensure that the whole floor, beautiful.
Second, the need to deal with the type of expansion joints Floor
1, Epoxy
2, acrylic stadium floor
3, silicon PU Stadium
4. Other floor (ground floor) system
Third, the basic cutting tool
Common ground joints processing machinery and equipment:
Name Use voltage range
Road cutting machine 380V large cutting
220V inclination angle grinder grind joints
Portable Cutting Machine 220V irregular fractured cutting and cutting small area
Fourth, polished ready
1. Check all wiring connections if there is damage, the series phenomenon, found damaged or short must immediately repair or replacement can not be forced feeder wires;
2. Check the grinding machine used is capable of functioning after connecting wires, loose or missing parts;
3. Wear good labor supplies, the need to protect the device with film or color of the cloth cover, to avoid contamination;
4, the original foundation if it is not cut expansion joints, elastic cord before fountain required cutting, cutting is necessary to form a straight line;
5. The use of voltage wires connecting the machine, when the wire feeder, should be selected in a stable and safe power distribution box were connected; the source of the power cord should be fixed up and then access, to avoid pulling the cutting process wire and ripped off a short circuit.
Fifth, the cutting procedure
1, a large area of the cutting must first play good fountain line according to the design, along fountain line straight cuts, cutting water machine should pay attention to the water tank, the water is too low half of the need for timely water;
2 large cutting machine after cutting finished, clean all the mud, then with the angle grinder to grind the joints on both sides of the diagonal into 45 °, a width of not less than 1 cm apart on both sides;
3, irregular craquelure, portable cutting machine required at least 2 cm deep cut along the crack, and the same on both sides using angle grinders will grind to a ramp 45 °, a width of not less than 1 cm.
Sixth, hygiene clean-up
1, clean up, the choice of a vacuum cleaner or a big broom, brush and a player to be equipped with the instruments pointing, mud and dust inside the joints must be clean when cleaning.
