Detailed Product Description: | 100 m high chimney sliding construction program Abstract] brief introduction Jiangsu Dafeng Sunshine Thermal Power Plant 100 m high chimney foundation construction, sliding construction technology, focusing on the aspects of the construction quality of the 100 m high chimney construction for the entire control. 1 Project Overview Jiangsu Dafeng Sunshine chimney power plant engineering, construction drawings numbered chimney 99SG212, height 100 m, inner diameter of the tube wall outlet 3? 3 m, the cylinder wall concrete C30. Form the basis for the slab foundation, the base portion, a bottom elevation of the foundation slab -4? 00 m in diameter at the bottom under the port 18? 58 m, the foundation slab outside of the high 1? 05 m, the center of a circle with a radius of 5? 45 m floor level in the range of 2? 1 m. Base ring wall height of 1? 9 m, chimney concrete foundation using C25, C10 cushion 10 cm thick concrete, concrete for the total amount of 470 m3. 2 foundation construction 2? A construction process C10 concrete pad poured → template installation (Brick form) → base floor concreting steel banding → → → steel banding cup-shaped base plate mounting → → concrete curing concrete pouring. 2? 2 Construction Method 2? 2? 1 basic template foundation slab construction with brick base template annular tire mold. Prior to 120 mm thick steel banding masonry brick red brick along the outside of the ring with a standard basis, the inside painting, based outside the ring as a template, the template using basic cup styling composition template. 2? 2? 2 construction joints leaving in accordance with construction specifications, chimney foundation construction joints should remain in the ring junction of wall and floor, can not remain in any other parts of industrial sewing facilities. Due to the high floor of the ring wall thickness at the intersection, according to the construction specifications set in the center of dowels, dowels model Φ12, spacing 300 mm, depth 500 mm. 2? 2? Erection of the project according to the characteristics of three large amount of concrete pouring platform construction must ensure smooth pouring platform. In order to make the project concrete pouring cold without leaving seam, using concrete pouring from around the middle of symmetry, so casting platform with full tang erection, erection part of the platform holder (steel) buried in the concrete foundation. 2? 2? 4 concrete foundation construction chimney using two self-loading concrete mixer with the chute will be transported to the construction site pouring concrete. Chimney foundation slab concreting symmetrical placement, will be divided into two construction workers pouring concrete pouring operations group were symmetrical, and on the basis of the center line of the rendezvous, the concrete chute decentralization adopted within the template. When pouring the foundation annular cylinder, the erection of three runways in the pit, with the car with the chute pouring, pouring pouring personnel from three directions, points the way to the slope hierarchical pouring pouring 3-point hierarchical forward displacement, each pouring thickness is about 300 mm. Plum-shaped vibrator mode by using the top-down vibration, vibration distance of not more than 300 mm. Plug-in vibrator vibrators into the concrete surface appear laitance, concrete is no longer fall so far. In order to make concrete the machine heat loss to a minimum, with the use of water with stirring, in the shortest possible time concrete transported to the site and were pouring immediately to ensure the concrete into the mold temperature of not less than 5 ℃. Concrete transport, pouring and intermittent full time should not exceed the initial setting time of concrete |
