Jiyuan rock swelling broken agent, blasting Jiyuan silent expansive Which is better? Static baopo in structural transformation Engineering carbatex silent soundless cracking agent client instance: a building construction area of ??66000m2, frame - shear structure, 3 basements, 15 floors. Structure construction process due to planning requirements need to be broken, anchorage or remove them from 5 to 15 part-situ concrete floor and roof beams. Because concrete is C40, reinforced floor is Φ12 @ 150 double two-way, Liang smaller cross-section, steel-intensive, high concrete strength, and are high-altitude operations, it is broken construction dangerous, technically demanding. 1, program selection (1) Construction requirements 1) removal of reservations should be broken as far as possible to protect steel, anchorage to reduce the amount of work, for which only the use of pneumatic drills, diamond can not be used. 2) To ensure that no disturbance is not opened structure, without affecting its strength. 3) Minimizing the site other machinery and equipment (such as cranes, outdoor elevator) with time jobs. 4) construction process from 5 to 15 layers from bottom to top, but 10, 11 layers from top to bottom construction. 5) prohibit falling objects and broken chunks of concrete to prevent falling, in order to avoid disturbing the underlying structure. (2) the program selected in accordance with the construction requirements and site conditions, the comparison using the first pre-split static baopo broken program, namely the use of the pre-split baopo principle, required to keep the structure from the outside 5cm first 1-2 rows of intensive drilling pores, as Static Breaking provide free face broken, the follow-up work to reduce the disturbance to the retention structure, and then need to remove part of the drilling, filling carbatex static crushing agent. After the concrete cracking, crushing with picks concentrate removal and retains its reinforcement. The program has a duration of suitable low cost, retains its bars, take a short time and the crane on the advantages of small structural perturbations, but the higher technical requirements for construction, need to pay close attention to safety during the construction. 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.
