OVM anchoring system of the Great Wall Pass Slope Reinforcement

l250007 in 577l00030007000 ~ 80007 in the 576l0OO2. Construction and manufacturing techniques into the hole: Construction at DTH hammer, drill on the shelf easy to install, easy to use a compass to adjust both the azimuth angle, azimuth angle side angle adjustment device for determining the dimensions in accordance with drill hole depth. In accordance with the design parameters into the holes in the drill diameter than the actual aperture l10 big 3 ~ 5mm. In addition, hole, when through the highly weathered rock or rock mass when the fracture zone. Blow wet yellow or yellow rock powder mixed with a number of original delivery (not fresh, non-break drill, the surface dull dull) rock body, which marks the hole collapse. At this point, immediately stop the drilling, pull out the drill, filling the solid wall, 24h and then re-drill hole, and blowing with compressed air channel. Code claimant claims: According to the design to determine the cable length,[link widoczny dla zalogowanych], with a wheel cutter to cut in order to avoid local temperature. Oriented according to design specifications tied hat rack placed isolation and lashing wire with No. l4; then penetration grouting pipe, cloth good test slurry level within the anchoring section of the wire; final method using human workers to sit in the right cable into the cable,[link widoczny dla zalogowanych], while injection of slurry pipe pressed into the air, to ensure that when you install the anchor hole wall fell on wet scraping dough blowing rock grouting within the anchoring section: because of all the holes for the next dump (2O.), Rotary work, grouting pipe inserted to the hole the end of the slurry from the bottom of the hole into the air by the cable vent slurry 425 with fresh ordinary Portland cement, water-cement ratio of 0.4. Sampled R28 ≥ 30.6N / [Tim:. Position control of the grouting, designed by our factory location of identifiable water and slurry control tester pouring reinforced concrete piers: the slope and anchor may not be vertical,[link widoczny dla zalogowanych], so both compression members reinforced concrete piers to 122 Anchor concentrated load evenly delivered to the mass, and force can be used to adjust the direction of the slope. In order to anchor pier on the surface and the vertical axis, pre-drill the same diameter with a diameter of thin-walled steel and prestressed anchor plate orthogonal weld, steel pipe before pouring concrete into the hole to the other end of pre- tensile stress: the tension before the matching of the supporting equipment to be calibrated. To install the pump according to records. Jack began to tension, while the seven strands are evenly, first to be used by root pretension YC20Q jack. Then sub-second 0-1OOkN a 1100kN (1l00kN for ultra-tension stress). OVM is based on the anchor,[link widoczny dla zalogowanych], anchor point is the tensile force applied to relax after the jack, was to produce a homogeneous clip into the anchor plate reverse movement conical hole. The self-anchored; then was the force stress transfer surface to form a permanent prestressing. Therefore, the correct installation of anchor clamps and tensioning equipment, the performance of the guarantee is necessary to anchor. Installation order: work work anchor plate clips, limit board, jack tools anchors, tools, clip (Figure 3) of them. Install limit board should pay attention to recognize signs, so as to avoid shrinkage increases or anchor within the mouth of the friction system sensitivity increases. Anchor simultaneously deal with the tools to anchor strand is twisted so that, should be painted on the tool clip anchoring spirits back to back anchor flexible. 3 Wu Tian tensioning equipment first startling I. Pi plate 2t central piece 3. Limit board I4. Jin Huang. 5. Tools anchor plate 6. Gongyiyangpian l. Strand secondary grouting: prestressed tension after super. Now a second grouting, the construction of the direct use of grouting pipe inserted into the anchoring section end. Side bags and side note, aside grouting pipe,[link widoczny dla zalogowanych], until the paste until the abuse of a reinforced concrete pier. V. Conclusion Juyongguan slope using sprayed concrete, sand holes bolt, prestressed cable supporting the joint program, complete control of the whereabouts of the slope surface of pumice stone, especially with large tonnage of tomato stress cable, which greatly limits the mountain scattered and creep deformation of the body to prevent the deep pity Dingshan moving this construction company focusing on the top of the rock bolt to be the Construction Method for Ding Youyi explore further promote OVM anchoring system in the small anchor application. Engineering practical proof: OVM anchors can meet the performance indicators and in line with post-tensioned Association International (PTI) The recommendations and national standards, is completely reliable and excellent. mAppHcatonotOVMAnchot-ln ~ Sy ~ 'mU. edtoCoasolid ~ teSlopeLiuXuanDengXueqi (Llughouc0moIIMeeh-GenerIl Nu o 『y, ulnoI1.Gmmgxl54500) grapefruit stare: _f spider lizard jumping larva cricket stare Greatnear fine, la cries of a roundworm Simulium H, but friends paid the state has removed plus larva m m He bend, butterfly Yao Rights snail, tec / mo / a ~ es fire commission has quiet West E foot lizard deleted.
