四、LD-211螺旋道釘錨固劑與硫磺錨固劑的對比:
4. LD-211 spiral screw anchorsvs sulfur anchors :
product
Performance Sulfur anchoring agent LD-211 screw spike anchoring agent
pulling resistance >60KN >90KN
Moisture insulation performance 1.5MΩ 50MΩ
Fatigue resistance 2 million times >6 million times
It does not produce any toxic and harmful gas substances. It is a environment-friendly anchoring agent.
五、施工工藝
1、孔洞處理:
錨固前應先將孔內和道釘表面的雜物、粉塵及油污鐵銹清除干凈。將道釘孔底部用木塞、粘土等堵嚴,防止漏漿。填充物上部距道釘孔上口應不小于135mm。
2、材料配制:
1)檢查產品外包裝,規格、型號、生產日期,確保產品在廠家規定的保質期內。
2)打開包裝桶蓋,檢查內裝A料、B料、C料均無破損、漏灑、受潮結塊現象,每桶中的裝配比例為A料:B料:C料=100:50:650。
3)攪拌配料時,先將A料倒入桶中,邊攪拌邊緩慢加入B料,攪拌均勻后再將C料倒入桶中,攪拌成均勻的稀膏狀。
3、錨固施工:
1)將拌合均勻的LD-211螺旋道釘錨固劑,灌注入道釘預留孔中,將道釘套入道釘錨固架從灌注孔上部壓入灌滿錨固劑的孔正中,轉動道釘并輕輕敲擊道釘上部,使錨固劑受振動達到密實。
2)道釘的錨固深度不得小于115mm。
V. Construction Technology
1. hole processing:
The debris, dust and oil rust on the surfaces of the holes and spikes should be removed before the anchoring. The bottom of the spike hole with a cork, clay, etc. to prevent leakage. The upper part of the filler should be not less than 135mm from the upper hole of the spike.
2.material preparation:
1) Check the product packaging, specifications, model, and production date to ensure that the product is within theshelf life.
2) Open the packaging lid, check the A, B and C materials are not damaged, spilled or damp, and the assembly ratio is A: B: C=100:50:650 .
3) When stirring the ingredients, first pour the A-material into the barrel, slowly add the B-material while stirring, and then stir the C-material into the barrel and stir into a uniform thin paste.
3.anchor construction:
1) Mix the uniform LD-211 screw spike anchoring agent, pouring itinto the hole , and put the spike into the center of the holewhichfilled with the anchoring agent, rotate the spike and Gently strike the upper part of the spike to make the anchoring agent vibrated to achieve compaction.
2) The anchorage depth of spikes shall not be less than 115mm.
六、注意事項
1、嚴禁使用未拌合均勻或處于初凝狀態的錨固劑,配制好的膠液應在30分鐘內用完。
2、錨固過程中嚴禁道釘與軌枕孔壁及底部填充物接觸以免影響絕緣效果。
3、孔底填充物要壓實,嚴禁粘附于孔壁,以免在孔壁與錨固劑之間形成隔離層影響抗拔效果。
4、嚴禁軌枕預留孔壁潮濕情況下錨固,以免影響抗拔效果。
5、A料和B料存放時間較長后會出現輕微分層現象,使用前應先搖勻方可使用。
6、在25℃環境溫度下,錨固完成24h后可上線受力,嚴禁提前受力,以免造成損壞。溫度**25℃時固化時間將相應延長。
6. Attention
1. It is forbidden to use the anchoring agent which is not evenly mixed or in the initial setting state. The prepared glue should be used within 30 minutes.
2. Do not allow the spike to contact the hole wall and the bottom filler during the anchoring process to avoid affecting the insulation effect.
3. It is forbidden to anchor anchors in the Damp environment so as not to affect the anti-pulling effect.
4. A and B should be shaking before used when stored for a long time.
5. There should no force between 24htoavoid damage, The complete curing time will be prolonged when the temperature is lower than 25°C.
