Description
Technical field
The utility model relates to a kind of single clearance type train coal receiving bunker concrete column strengthening reconstruction structure, relates in particular to a kind of steel and concrete combination column structure.
Background technology
At present, the large-size thermal power plant train is unloaded coal and is mainly contained following several mode: the one, and the coal-fired transportation of standard gage railway open-top car, the employing tipper unloading in the power plant of adopting; The 2nd, the coal-fired bottom drop car that adopts transports, and the train clearance type coal ditch that suitable parking stall is set in the power plant is unloaded; The 3rd, the coal-fired standard gage railway open-top car that adopts transports, and screw unloader is set in the power plant unloads.Generally speaking, the standard gage railway open-top car is provided by railway interests or colliery, and bottom drop car is because its particularity of unloading needs power plant to provide for oneself." steam power station designing technique rules " are 7.2.3 and 7.2.5 bar regulation (DL500-2000): railway comes the power plant of coal, when coal consumption 250t/h and more than, or station capacity is at 400MW and when above, can consider that dumptruct unloads coal; Coal consumption 350 ~ 800t/h and more than, or station capacity can arrange two dumptructs at 600MW and when above; The coal tripper of screw unloader and slot type coal hopper should be used for capacity and be no more than the power plant that 600MW or coal consumption are not more than 350t/h.Wherein, bottom drop car is a kind of open hopper wagon, is applicable to fixing marshalling, fixed point loading and unloading, recycles, and the operation efficiency height is arranged, unload advantages such as vehicle speed is fast, is applicable to the power plant that haul distance is nearer, ore deposit point is concentrated relatively, wheel is fixed, raw meal particle size suits.But the design feature of bottom drop car self has determined it to have the following disadvantages in power plant's practical application again: 1. automaticity is low; 2. power plant need all buy by oneself at the bottom of the car, and car purchase fee is with higher; 3. relatively poor to the compliance of power plant's coal source variation; 4. to freezing coal, coarse coal bad adaptability; Coal dust is raised outward when 5. unloading, and surrounding environment is more abominable.Therefore, existing power plant transforms single line clearance type train coal receiving bunker, changes its mode of unloading coal into screw unloader and unloads coal.For guaranteeing screw unloader normal operation use on original coal receiving bunker structure, differ bigger through adjusting original coal receiving bunker concrete frame trestle section and design section, need carry out increasing section to concrete column and reinforce.
At present, common concrete strengthening form has: concrete strengthening, steel-bonded reinforcement, carbon fiber reinforcement etc. are reinforced, replaced to conventional enlarging section method.But, available coagulation earth pillar reinforcing form has its weak point, as: conventional enlarging section method is reinforced and is newly-increased steel bar stress and stirrup in former concrete column border (or both sides), formwork, concreting, but the New-old concrete co-operation is bad, the cooperative transformation poor performance, and owing to influenced by formwork and concrete curing, construction period is longer, also has certain potential safety hazard when constructing under former train coal receiving bunker operating condition; Though the displacement concrete strengthening does not reduce usage space, the anti-bending strength deficiency of concrete component; Outer steel bonding plate, angle steel construction quality are difficult to control, cannot say for sure to demonstrate,prove the globality of steel plate or angle steel and original concrete column, and be low to the concrete horizontal restrain, cost height, and effective increasing section size; Carbon fiber reinforcement involves great expense, and can not effectively improve sectional dimension equally.
