Xiangtan stone crusher where agents buy? Direct factory Xiangtan silent expansive static baopo in construction renovation project application carbatex silent soundless cracking agent client instance: a building construction area 66000m2, frame - shear structure, 3 basements, 15 floors. Construction process, construction planning requirements need to be broken because of its 5 to 15 layers, some cast concrete beams and roof, anchorage or withdrawn. Because concrete is C40, reinforced floor is Φ12 @ 150 double two-way, Liang smaller cross-section, reinforced dense, high strength grade concrete, and are working at height, so the risk of broken construction, high skill requirements. 1, plan selection (1) Construction demand 1) the removal of broken due perhaps to save, safeguard steel, to reduce the workload anchorage, for which only use pneumatic drills, can not use stones. 2) To ensure that no disturbance is not opened structure, without affecting its strength. 3) Make the cut scene perhaps other machinery and equipment (such as cranes, outdoor elevator) with the work of the moment. 4) construction process from 5 to 15 layers from bottom to top, but during the construction of the first 10, 11 layers from top to bottom. 5) stop falling objects and broken eradicate falling chunk of concrete, to avoid disturbing base construction. (2) Program selection based on site conditions and construction demand, by comparison to the pre-selection of static baopo broken after split plan, that the use of pre-split baopo principle in 5cm intervals should be kept outside the structure by drilling one or two rows of dense voids for Static broken broken free supply side, reducing follow-up to save the structure of the disturbance, and then need to remove some drilling, filling carbatex static crushing agent. After the concrete cracking, crushing removal with picks will be set and saved during the rebar. The program has a time limit for low cost, can save during the bars, take a short time and for construction crane minor disturbances strengths, but a higher demand for construction skills required close attention to safety during the 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 swell, so slow and quiet will swell pressure 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 which the effect of the tensile stress can 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 the open V-shaped grooves cause double-free work surface, inclined 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. Preparation and filling in accordance with (3) broken agent season is not the same selection of different carbatex static crushing agents, water-cement ratio the greater the swelling pressure, the longer response time to swell. Taking into account the liquidity of the construction demolition agent, when mixing cement ratio of 30%. Artificial mixing slurry horizontal hole with a smaller water-cement ratio, and corked fill in opening with a sponge or a thick creamy dry clay-like plunge hole in demolition agent tamping bar 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 stone crusher agent Xiangtan Where to buy?
