檢測器環(huán)路-中英對照

每只支架包括可移動封蓋、電線出路的金屬孔眼、托架和信號吊架組件的型號、數(shù)量和位置必須在圖紙上標(biāo)出。
1.柱子可以選擇整塊鋼底座,要求符合A36 ASIM的規(guī)定,或者采用鑄鋼錨栓基座,要求符合A27 ASTM,等級65-35的規(guī)定。
m. 采用兩個連續(xù)的焊接點嵌入柱子進行保護,一個焊接點在柱子內(nèi)側(cè),另一個在柱子基礎(chǔ)的頂部外側(cè)的末端上。
3.完工:全部鋼材組成部分必須經(jīng)過熱浸鍍鋅處理,并且符合第09875 部分防腐蝕條款的規(guī)定,獲得皇室委員會的批準(zhǔn)。
H.混凝土材料:混凝土和其它基礎(chǔ)材料必須符合03300部分的規(guī)定,"現(xiàn)場澆注混凝土"包括防水防腐蝕保護和絕緣板。
I 檢測器環(huán)路:
1.環(huán)路檢測器電線由2.5毫米、90°C組成。600 V標(biāo)準(zhǔn)電線帶有2個通過環(huán)路的彎角。 環(huán)路末端留有大約2米長環(huán)線,留有通信口方便接入。
2. 承包商有責(zé)任削減圖紙中規(guī)定管溝的尺寸和形狀,承包商也可以從每個環(huán)到路線的邊緣切一個管溝引線。環(huán)路的轉(zhuǎn)角可以斜切。保證管溝干凈平整。所有的削減由一條單個的圓形通道完成。

3.管溝為褐色,在切割后不得有任何碎片和水分留在管溝內(nèi)。如果環(huán)線沒有立即安裝,安裝皇室委員會的要求,為防止槽口崩塌,承包商必須安裝一根木頭或者其它填料。如果環(huán)路的施工要求有路肩,在車行道水平下面和信道的終端必須安裝一條導(dǎo)管通過路肩。
4.形成環(huán)路的電線在其整個長度必須保持連續(xù),并且安裝不得有任何捻接。環(huán)路電線從管溝延伸到最近的通信口。從這里接入到環(huán)檢測器并進行密封。
5.環(huán)檢測器電線必須采用以下方式安裝。管溝為褐色,在切割后不得有任何碎片和水分留在管溝內(nèi),電線的轉(zhuǎn)角處必須放在入槽內(nèi),不得有紐結(jié)或者卷曲,在槽角落絕緣材料周圍不得有拉緊或者伸展。將一根圓角木頭放在管溝的底部方便安排電線。在電線安置后,檢查電線是否松弛,拉出以部分,檢查是否繃緊。 如果發(fā)現(xiàn)有任何上述問題,立即進行改正。
 Each arm to include removable cap for tip, grommeted wire outlets, sign support brackets, and signal hanger assemblies of type, quantity and at locations shown on drawings.
1. Poles to have either a one piece steel base plate meeting requirements of ASIM A36 or a cast steel anchor base meeting requirements of ASTM A27, Grade 65-35.
m. Base to telescope the pole and be secured to pole with two continuous welds, one on inside of base at end of pole and, the other on outside at top of base.
3. Finish: All steel components shall be hot dip galvanized and corrosion protected in accordance with Section 09875 and as approved by the Royal Commission.
H. Concrete Materials: Concrete and' other materialist for foundations shall comply with Section 03300, "Cast-In-Place Concrete" including waterproofing corrosion protection and insulation board.
Detector Loop:
1. The loop detector wire will consist of 2.5-mm 90°C. standard wire 600V with two turns through the loop. The ends of the loop wire about 2 meters long will be left in the handhole for splicing purposes.
2. It will be Contractor's responsibility to saw cut a trench of the dimensions and shape specified in the approved drawings. The Contractor shall also saw cut an access trench from each loop to the edge of the route. The corners of the loops shall be cut diagonally to. assure a clean, smooth
 
trench. All cuts shall be accomplished in a single pass with a circular pavement cutting saw.
3. The trench shall be blown free of debris and moisture after the trench has been cut. If the loop wire is not immediately installed the Contractor shall install either a wood or other filler, approved by the Royal Commission, to prevent the slot from collapsing. If a curb is proposed for construction where the loops are being installed, a conduit shall be installed through the curb below the roadway level and terminate in the access channel.
4. The wire forming the loop shall be continuous throughout its length and installed without splices. The loop wire shall extend from the trench to the nearest handhole. At this point they shall be sealed for future splicing to loop detector leads.
5. The loop detector wire shall be installed in the following manner. After the trench is blown free of debris and moisture, the turns of wire shall be laid in the slot so that there are no kinks or curls, and no straining or stretching of the insulation around the corners of the slot. A piece of wood with rounded corners shall be used to seat the wire in the bottom of the trench. After the wire is placed, it shall be rechecked for slack, raised portions, andlor tightness. if any of the foregoing are found, they shall be corrected.
