Grouting 1 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, equipment: ① sweep hole drilling and equipment: hand-drilling rig (SG-100), a hand-held impact drill (ZIC.QC-22). ② slit equipment: 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 tank (homemade). ⑥ measuring equipment: glass rotor flowmeter (LZB-10), cup (various models), Scales (TGT50-1000GAJF). 1.3 Process embedded grouting pipe ventilation methods can be checked. 1, embedded grouting pipe available under the case: preparation → Ventilation → grouting → Check → sweep hole irrigation repair grout holes. 2, embedded grouting tubes could not be used under conditions: preparation → drilling → Khong → pipe → Ventilation → grouting → Check → sweep hole irrigation repair grout holes. 1.4 construction method, embedded grouting pipe construction method can be used in case of (1) Preparation according to the location of surface water seepage, determine the need for the erection bay, and then do the seepage situation described. (2) The opening will be closed on both sides Deformation debris floating pulp grinding, cleaning. Rinse with water, air-dried by plugging Ling closure seams 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 pore volume and collusion based on each hole, the partial deployment of grout, the first stock preparation line should be greater than the pore volume accounted for the amount of pulp. From low to high perfusion sequence, because the curing properties of polyurethane materials, grouting hole grouting adopt appropriate. Grouting pressure is 0.4Mpa ~ 0.5Mpa, grout injection rate observed at any time, to ensure a full grouting filling to achieve an effective seal. Good chemical grouting original records and results tables. Within 5min hole injection amount is less than 100ml, the pressure increased to 0.7 ~ 0.8Mpa. Within 5 min injection hole is larger than 300ml, reduced pressure or adjust the gel time applying grout filling. ⑸ ① surface quality inspection checks: After grouting process 14d, to check whether Deformation surface water seepage, if there is no water seepage, it is judged that the surface inspection and approval; ② internal examination: surface inspection and approval, and then the internal inspection method through a single point water pressure test pressurized water pressure 0.6 Mpa, the number of holes 5% single Deformation number of holes, holes in the original grout hole optional, or grout slurry larger and string holes, and some suitable arrangement on Deformation, aperture is Φ32mm. Pressure water check eligibility criteria for the water permeability q≤0.1Lu, and no dampness blot again; ③ before the final examination if to seepage deformation crack appeared in 14d, the need to take the following approach to deal with: a portion of the water seepage. once again grouting process;. b After filling, the side walls and roof in and around the site with concrete seepage chasers in Deformation Slotting (wedge-shaped cross section), the groove depth 125px, surface width 125px, maximum internal width 150px. After opening wedge grooves, cut with a concrete cutting sewing a seam on a movement joint, seam width 75px, deep seam 5 ~ 150px. Then buried in the vertical movement joint in the concrete surface drilling grout pipe, diameter 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 grooves, and then buried in a good use of water-soluble polyurethane grouting pipe perfusion filled, injection pressure of 0.4 ~ 0.5MPa. 2, embedded grouting tube construction method is not available in case of (1) 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 Deformation from both sides 18 ~ 500px vertically on the concrete surface by drilling or drilling embedded grouting tube position, diameter 12 ~ 20mm, pitch 875px, plum-shaped layout, through the hole depth stop Hose 2 ~ 75px, shown in Figure 3.1-5. ② 12 ~ 20mm opening four weeks will be cutting hair treatment, after buried grouting pipe (3) clear aperture hole with submersible pump clean, requiring clean, Paradise, good clean hole tables. (4) pipe using early strength cement pipe, requiring formation density. (5) opening a closed tube with embedded grouting construction method availability. (6) ventilation ventilation checking oil-free air compressor drilling effect, 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 inspection with embedded grouting pipe construction method of availability. 1.5 special case in the grouting process, when there is a string of adjacent wells pulp, pulp string holes should be closed immediately to ensure that the slurry filled full, or caulking surface leakage should be stopped immediately applied irrigation, reclosable grouting. When the injection is too large, grouting hole than 50ml / min, and can not afford when pressed, can be taken down, shortening the slurry gel time, the 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 when the feed slurry is excessively large, the consent of the site supervision engineer, part of the water can be injected into the mud, then chemical grout perfusion. Individual grout great pressure not afford to bore section, in identifying the cause newspaper Engineer Process. Filling job interruptions should be resumed as soon as possible perfusion. When the restore perfusion, significantly reducing the amount of grout should separately fill hole perfusion. 2 construction joint seepage treatment construction joints in waterproof design has embedded grouting pipe, construction joint seepage treatment in two cases: the case of grouting and grouting pipe can be used in both cases the tube can not be used for construction joints treated .
