Grouting an auxiliary materials and tools, high pressure pipe, hose. 2, pliers, wrenches, wire. 3, pipe material: early strength cement (mixed with quick-setting cement material material). 4, the device: ① sweep hole drilling and equipment: Handheld Rig (SG-100), handheld percussion drill (ZIC.QC-22). ② lancing device: Concrete cutting and sewing machine. ③ hole cleaning equipment: high pressure water gun. ④ Ventilation: oil-free air compressor (Y112M-4). ⑤ grouting equipment: hand-pressure grout pump (HY-1), injection pump (homemade), slurry storage barrels (homemade). ⑥ metering equipment: glass rotameter (LZB-10), cup (various models), scales (TGT50-1000GAJF). 1.3 embedded grouting process ventilation tube method can be checked. 1, embedded grouting pipe under availability: Preparations ventilation → → → filling examination after grouting hole repair grout hole → sweep. 2, embedded grouting pipe not the case of using: Preparations clearance hole drilling → → → → ventilation pipe grouting → → → sweep irrigation inspection hole repair grout holes. 1.4 Construction Method 1, embedded grouting pipe construction methods are available in case of (a) the preparation according to the location of surface water seepage, decide whether the erection bay, and then do the water seepage description. (2) on both sides of the orifice closure of Deformation debris floating pulp grinding, cleaning. Rinse with water, air-dried by plugging Ling closed seam closed width 175px, thickness 75px, requires sticking closely, no leakage of plasma. In addition, the exhaust pipe buried along Deformation, spacing 1m. Blocking material cleared after quality inspection. ⑶ ventilation checking oil-free air compressor ventilation, ventilation pressure ≤0.25Mpa, good ventilation record. ⑷ grouting collusion based on pore volume and each hole, the partial deployment of grout, first prepare the slurry pipeline should be greater than the pore volume accounted for plasma volume. From low to high perfusion sequence, because the curing properties of polyurethane materials, grouting hole grouting using appropriate. Grouting pressure is 0.4Mpa ~ 0.5Mpa, grout injection rate observed at any time, to ensure a full grouting achieve an effective seal. Good chemical grouting original records and results table. Within 5min hole injection amount is less than 100ml, the pressure is increased to 0.7 ~ 0.8Mpa. Within 5 min injection hole is larger than 300ml, reduce stress or grout gel time adjusting irrigation facilities. ⑸ ① surface quality inspection check: After grouting treatment 14d, check whether Deformation surface water seepage, if there is no water seepage, surface inspection is to determine eligibility; ② internal inspection: After surface inspection and approval, and then checked by a single point inside water pressure test method pressurized water pressure 0.6 Mpa, the number of holes 5% single Deformation number of holes, the holes in the original grout hole optional, or suck on a larger amount of pulp and pulp string holes, and some suitable arrangement on the Deformation, aperture is Φ32mm. Water pressure check eligibility criteria for water permeability q≤0.1Lu, and no dampness blot again; ③ before the final examination if they appear to seepage of Deformation in 14d, the need to take the following approach to treatment: a part of the seepage. once again grouting treatment;. b After filling, the side walls and roof for the site and in the vicinity of seepage with concrete cutting and sewing machine in Deformation Slotting (wedge-shaped cross section), the groove depth 125px, surface width 125px, internal biggest width 150px. After opening wedge grooves, cut with a concrete cutting sewing a seam on a movement joint, seam width of 75px, deep seam 5 ~ 150px. Then buried in the vertical movement joint in the concrete surface drilling grouting pipes, aperture 12mm, pitch 2500px, deep hole through the slit depth of about 125px. After completion of drilling pipe with epoxy mortar to fill the dense wedge slot, and then use the buried pipe perfusion good water-soluble polyurethane grout filled, injection pressure is 0.4 ~ 0.5MPa. 2, embedded grouting tube construction method is not available in case of (a) the preparation according to the location of surface water seepage, determine the need for the erection bay, and then do the sewing surface seepage description. (2) Drilling ① from Deformation at 18 ~ 500px sides perpendicular to the concrete surface by drilling or drilling embedded grouting tube position, aperture 12 ~ 20mm, pitch 875px, plum-shaped layout, only through the hole depth water with 2 ~ 75px, shown in Figure 3.1-5. ② the 12 ~ 20mm orifice four weeks before cutting hair treatment, after buried grouting pipe (3) clear aperture hole with submersible pump clean, requiring clean, Paradise, good hole cleaning tables. (4) the use of early strength cement pipe buried require smooth dense. (5) with embedded grouting pipe orifice closed availability construction methods. (6) ventilation ventilation checking oil-free air compressor drilling results, the ventilation pressure ≤0.25Mpa, ventilation ratio of 100 the number of ventilation holes 5, good ventilation record. (7) with embedded grouting pipe grouting construction method of availability. (8) Quality Check with embedded grouting tube construction method of availability. 1.5 special case in the grouting process, when there is a string of adjacent holes pulp, pulp string holes should be closed immediately to ensure full filling slurry, or caulking surface leakage irrigation facilities should be stopped immediately, re-grouting closed. When excessive for injection, grouting hole than 50ml / min, can not afford the time and pressure, can be taken down, shorten time to gel slurry, slurry viscosity increases perfusion, or the use of intermittent grouting treatment, usually intermittent time may be 8 ~ 12h. Deformation due to the large gap, so that when the slurry into excessive when, after the consent of the site supervising engineer, part of the water can be injected into the mud, and then chemical grout perfusion. Individual grout is large, can not afford to pore pressure section, in identifying the reasons for the Engineer Research report processing. Grouting work interruptions should be restored as soon as possible perfusion. When the recovery perfusion significantly reduced the amount of grout should be separate perfusion fill holes. 2 construction joint seepage treatment in a waterproof design construction joints in the grouting pipes embedded in the construction joint seepage handle two cases: cases grouting pipe can be used and the grouting pipe can not be used for construction joints in both cases handled .
