Huanggang silent broken agent, Huanggang static expanders, stone crushing a helper, material requirements Jiazejiaze silent broken agent model temperature range (℃) swelling pressure (MPa) 8 hours 24 hours 48 hours I 20--40 ≥30 ≥ 55 ≥90 II 10--20 ≥20 ≥45 ≥60 III -5--10 ≥10 ≥25 ≥35 Second, the main machinery equipment 1. Drilling equipment: with an internal combustion rock drill, pneumatic drills and adapt compressor, drill rod, drill, duct, pipe, gun club, hair tubes. Drill diameter 35 ~ 50mm. Gun stick with wood processing, diameter 30mm, length 1.5m, hair effective ∮25mm steel processing. 2. Oxyacetylene cutting equipment steel cutter. Charge stirring machine with a plastic tube, plastic boxes, plastic bailer, each two plastic funnel, stirring 2 to 3 sticks. Enamel or glass measuring cup (volume 100mL) 2 只. Restructuring of the blender with a small drill 1 to 2 units. High sleeves rubber gloves, protective glasses, masks and a few pieces. Third, working conditions 1. Before crushing response building (structure) building materials of construction, nature, work environment, engineering, requires fragmentation, schedule requirements. The temperature, the steel reinforcement specifications and conduct a detailed investigation. Preparation of design crushing, crushing agent is selected according to the actual situation, determine the desired drilling parameters, drilling and crushing distribution program. 2. Foundation, soil trailer coupling, underground facilities or crushed rock should dig around until the break below the bottom of 100 ~ 200mm. 3. When removing the concrete, it should identify the distribution of steel, and then drilling, and will be part of the stirrups and vertical ribs broken body with oxyacetylene flame cut. Fourth, the construction operation process 1. The construction program is still broken: broken structure (body) survey design → → broken broken agents select parameters → drilling → drilling off part of reinforced → filling perfusion → Health → secondary crusher → cleanup. 2. Hole layout structure according to the degree of freedom of the case may be, or as much as possible to create the free surface, take a different approach different city-hole free surface. You can take vertical, horizontal, diagonal, etc. Arrangement of Holes. SCA uses Jiaze broken forms carbatex silent broken agent, drilling parameters refer to Table 2-8 use. Hole Jiaze static crushing agents to be broken object reference exemplar 2-8 Jiaze drilling parameters agents SCA crushing amount (kg / m3) aperture d (mm) pitch a (cm) resistance line W (cm) hole depth l soft rock crusher 40 ~ 50 40 ~ 60 30 ~ 50 H 8 ~ 10, the hard rock crusher 40 ~ 65 40 ~ 60 30 ~ 50 1.05H 10 ~ 15 hard and soft rock cutting 35 to 40 20 to 40 100 ~ 200 H 5 ~ 15 unreinforced concrete 35 ~ 50 40 ~ 60 30 ~ 40 0.8H 8 ~ 10 reinforced concrete foundation, columns, beams, walls, plates 35 ~ 50 15 ~ 40 20 ~ 30 0.9H 15 ~ 25 35 ~ 50 10 ~ 30 20 ~ 30 0.9H 15 ~ 20 Note: H crushing is highly object program; however distance b = 0.6 ~ 0.9a. 3. Should be strictly in accordance with the design requirements of the job blasthole location, direction, angle, depth drilling facilities. Blasthole drills after all, have to use a hair blow tube boreholes and water exchange or cotton waste, waste paper and other openings to be blocked in charge. 4. Mixing: When using carbatex SCA broken agent broken agent, generally water-cement ratio of 0.30 to 0.35, the bag (weight 5kg) broken agent, add water, 1.5 ~ 1.75kg. When mixing, the first quantitative broken agent who fall within the plastic container, and then slowly added to the gauging water, mechanical or manual mix into a homogeneous slurry having fluidity alternate. Requirements mix, mixing time is no more than 3min. Such as the use KE crusher agent, first with a graduated cylinder to take the required number of liquid (liquid 303) plus the amount of water needed, stir with a stick, to dissolve uniformly, and then the master agent (powder) and the required adjuvants were mixed uniformly.
