Shiyan rock crushing agent, Shiyan static expanders: Well pile subway tunnel rock excavation material 2, non baozha of carbatex silent broken agent Product Features carbatex is a non-silent expansive demolition agent baozha of products for cutting and breaking rock, concrete structures efficiently expandable material powder. With the amount of clean cold water and stir into the broken agent slurry, poured concrete and rock drilling may be generated 120MPa (1200kg / cm 2) the expansion pressure, over time, they can in no vibration, no noise, no By flying rocks and no gas situation the concrete and rock crushing, cutting. 2.1 Jiaze disregard expansive security is safe, no vibration, noise, flying rocks and gas in the crushing objects safe operation under polluted conditions. 2.2 Non-baozha of carbatex silent expansive non baozha of items not classified as dangerous goods, and general cargo as purchase, transport and use. Not subject to national dangerous goods, baozha product management restrictions. 2.3 Jiaze environmental protection products are environmentally friendly. Use no ground vibration, no noise, no flying rocks, no gas, no dust, no shock and no harmful substances to the environment, it is an international popular environmental pollution Jiaze products. 2.4 versatility carbatex product by adding proper hydration inhibitor to regulate the reaction rate at different temperatures, as an alternative to traditional demolition agent, based on the use of the operating environment temperature is different, choose different carbatex product models, work efficiency and operability can greatly improved. 2, static baopo design (1) Static Static baopo baopo principle is hydration carbatex use static crushing agents installed in the borehole, the crystal deformation volume expansion, so slow and quiet pressure is applied to the expanded empty hole wall. Due to space constraints of the cell wall, this expansion pressure into tensile stress, tensile strength of concrete is generally only 1.5 ~ 3MPa, in which the tensile stress can lead to broken down. Tests show that the expansion pressure carbatex static crushing agents produced in the borehole generally up to 30 ~ 80MPa, can fully guarantee the concrete in the absence of vibration, noise, flying rocks and gas security crack broken. (2) blasthole design 1) floor broken. 170㎜ thick slab, with a double in the two-way Φ12 @ 150 steel, dense pores 15 to 17㎝ hole depth, spacing A = 10cm, row spacing B = 10cm, aperture 40 mm. Inclined drilling method may be increased so that the length of the hole caused by the open V-shaped groove double free surface operations, oblique hole depth 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, can be partially stripped two layers of reinforced under the circumstances, and then drilling broken; hole depth L = 0.9 × beam height, spacing A = B = 15 cm; pore diameter of 40mm. 3) wall broken. Drilling may be top-down or use the wall holing way broken. (3) preparation and filling broken agents use different carbatex static crushing agents depending on the season, the greater the water-cement ratio, the expansion pressure is smaller, the longer the expansion reaction. 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 with a dry thick clay-like demolition agent twist strips stuffed tamping and plugging the hole from the outside. Oblique hole or down hole poured directly. 3, broken construction using an electric air compressor 1, drilling machine, a small number of picks. (1) the construction process intensive pre-split drilling → drilling blast holes filled with broken agent blasthole → mixing broken agent → perfusion filling broken agent broken → → small picks for retention structure using artificial or small picks tick cutting process. (2) Construction Safety Measures 1) because the Department of high-altitude operations, workers need to wear seat belts, wearing helmets. 2) strictly in accordance with the requirements of the cloth hole drilling operations, in order to guarantee a pre-pre-crack and break substantially complete. 3) mixing, filling, broken perfusion agents use picks broken, you should wear protective glasses, mixing personnel need to wear rubber gloves job. 4) good broken barricade enclosure floor and work the lower support beam, in order to avoid falling debris. Jiaze silent demolition agent static crushing, construction of no vibration, no shock, no flying rocks, both to ensure the construction safety and schedule, and to ensure the integrity and strength of the structure is not removed, can achieve better results. Lossless static cutting demolition techniques damage the structure of the problem in the reinforced concrete structure for opening holes and partial elements removed, how to avoid hammering and other destructive conventional construction methods, the client company to introduce a variety of construction machinery, construction equipment by professional local processing does not cause any damage to the surrounding structure, and strengthening its members around the hole according to the actual situation.
