Hengyang dickite expanders, Hengyang silent broken agent used for mine construction 2, static baopo Planning (1) Static baopo principle is to use static baopo installed in boreholes in the hydration reaction carbatex soundless cracking agent, the crystal deformation volume swelling occurs, then slowly and quietly to swell pressure is applied to the walls of the pores. Because the walls of the pores were bound, this swelling pressure into tensile stress, tensile strength of concrete is usually only 1.5 ~ 3MPa, in this stretch under stress easily lead to broken. Test indicated, swollen static pressure carbatex demolition agent occurring in the borehole typically up to 30 ~ 80MPa, can ensure plenty of concrete without sensation, noise, flying rocks and gas security crack broken condition. (2) blast hole planning 1) floor broken. 170㎜ thick slab, with a double in the two-way Φ12 @ 150 steel, dense pores hole depth of 15 to 17㎝ from A = 10cm, row spacing B = 10cm, aperture 40 mm. Optional oblique way that the length of the drill hole to increase, through open V-shaped groove to form a double free surface work, slant-hole depth of 20 cm, pitch A = 20 cm; row spacing B = 20 cm. (A) cross-sectional view; (b) plan 2) Beam broken. Beam, under reinforced both Ф25, partially stripped two layers of reinforced according to the situation, and then drilling broken; hole depth L = 0.9 × Leung, from A = B = 15 cm; pore diameter of 40mm. 3) wall broken. Choice of top-down selection of drilling or wall holing the way broken. Manufacturing and filling in accordance with (3) breaking agent is not the same as the season is not the same selection Jiaze static crushing agents, water-cement ratio the greater the pressure on the smaller swell, swell response time is longer. Taking into account the liquidity of the construction demolition agent, when mixing cement ratio of 30%. The slurry was agitated with artificial horizontal hole with a smaller water-cement ratio, and corked fill in opening with a sponge or a thick creamy dry clay-like strip inserted into the hole in the broken agent tamping and blocked from the outside. Oblique hole or down hole poured directly. 3, broken construction using electric air compressor 1, drilling machine, a small number of picks. (1) pre-split clouds construction process blasthole drill drill fill broken agent → → mixing broken agent borehole filled broken → perfusion agent picks broken → → small structure to save or small artificial selection process picks tick chisel. (2) Construction Safety Measures 1) because the Department working at height, workers need to wear seat belts, wearing helmets. 2) Hole in strict accordance with the needs of the drilling work to ensure that the pre-pre-occurrence of cracks and broken completely full. 3) mixing, filling, filling picks broken broken when agents use, the need to wear protective glasses, mixing personnel need to wear rubber gloves to work. 4) do the lower part of the support and work broken guardrail enclosure floor beams to prevent pieces from falling. Jiaze silent demolition agent static crushing, construction no sensation, no shock, no flying rocks, both to ensure the safety and construction period, but also to ensure the integrity of the structure is not removed and the strength, to get a better effect. Non-destructive removal of static cutting skills for the reinforced concrete structure open holes and some elements removed, how to prevent hammering and other destructive form of conventional construction approach to this problem structure damage, the client company to introduce a variety of construction machinery, construction equipment professionally part of treatment does not form any damage to the surrounding structure, and based on the actual situation of the hole to reinforce its peripheral members. Jiaze silent static crushing agents goods (procedure: drilling → stirring → grout → cracking) for pore size, pore depth, pitch has certain needs, and not the same season is not the same rock slightly different, please do not ignore accurate methods of operation, ability to ensure the goods reach a very good role.
