Description
Technical field
The utility model relates to the To Construction of Silo field, especially a kind of Hoisting System of the wholecircle template for To Construction of Silo.
Background technology
At present, the concrete conventional lining mode of power station pressure regulation vertical shaft mainly contains two kinds: the one, and adopt combined steel formwork to build, template is taken off, formwork erection all adopts manual type, utilizes the scaffold of setting up to come formwork.But this mode construction working amount is large, and construction is long circulation timei, and construction speed is slow.The second way is to adopt vertical shaft hydraulic slip-form mode to water building lining, and the vertical shaft hydraulic slip-form is the comparatively ripe mode of present pressure regulation vertical shaft lining cutting.
According to shaft structure pattern and layout feature, its hydraulic slip-form system mainly is comprised of template system, operation platform system, hydraulic lifting system and accessory system etc.Take the bottom of precoating as the basis, establish at a certain distance one, metal support bar, the hollow hydraulic jack is sleeved on every cramp bar, by bolt, the top of the base of hydraulic jack and cantilever hoisting frame is linked together, template is suspended on the cantilever hoisting frame, and hoisting frame adopts the surrounding space frame structure.Template and scaffold adopt adjusts the screw mandrel stretching.For the ease of construction, lay plank at the top of scaffold, with stacking equipment and material, bottom suspension suspension bracket platform concrete coating and watering, spray are protected.Adopt the mode of serial or parallel connection to be connected with hydraulic control system the grouping of all hydraulic jack.Like this, along with concrete the solidifying in template bottom, when template lower floor concrete reached demoulding condition, the operation hydraulic mechanism drove all hydraulic jack, just can drive hoisting frame, scaffold, template etc. along the cramp bar upward sliding, until can build the position of one deck concrete.So circulation is until the vertical shaft top.Sliding mode design can be with reference to the relevant requirements in standard GB/T J113-87 " Technical code for construction using hydraulic slip formworks ", but this kind lining cutting mode can only be built from bottom to top.
It is stable that the lining cutting mode of vertical shaft hydraulic slip-form requires to excavate the location geologic structure, the guarantee construction safety.For the broken unstable situation of geologic structure, especially thin when borehole wall surrounding rock body, when one-tenth well condition is very poor, excavation area and the degree of depth of vertical shaft are larger, and the borehole wall may cave in, and the application shaft hydraulic slip-form can not guarantee construction safety.For safety and the construction speed that guarantees to construct, can only adopt limit Wa Dajing, limit to beat the parallel operations construction operation method that anchor pole linked network concrete, limit water the reversal of the natural order of things concrete guard wall.Therefore breast wall concrete can only be poured into a mould from top to bottom in this case, can not be with conventional hydraulic slip-form lining cutting.But how to hang upside down concrete, become the difficult problem that needs solve.
If the reversal of the natural order of things concrete construction according to prior art, adopts the large-scale combined steel form to build, on the one hand, set up the construction working amounts such as scaffold, formwork large, construction is long circulation timei, can not in time seal the country rock of exposed fragmentation.And combined steel formwork builds the reversal of the natural order of things concrete to large well excavating sequences construction serious interference, and is very large on the construction speed impact of whole engineering.
Hang upside down long deficiency of concrete construction duration in order to overcome existing large-scale combined steel form, proposed to carry out top-down concrete pouring construction with a kind of whole upset hanging template of wholecircle that can hang upside down concrete construction, to shorten the constructure scheme of construction period.in imagination, the whole upset hanging template of this wholecircle comprises the pattern board supporting framework, the template assembly, be connected to the mould plate supporting device between template assembly and pattern board supporting framework, the template assembly comprises that wholecircle side form and die face are the inclined-plane bed die of frustum cone side, the die face baseline of described inclined-plane bed die and the axial line of wholecircle side form are the angle of acute angle, match with the wholecircle side form in the upper end of inclined-plane bed die, the lower end is positioned at the outside of wholecircle side form, reduction along with the concreting position, wholecircle side form and inclined-plane bed die also will descend thereupon, thereby consist of progressively downward concreting position in storehouse, this just needs to consider the fixing of a complete set of template, the demoulding and lifting, also to consider the uniformity that template is stressed.
For addressing the above problem, also can follow beyond example at present, but obviously can not indiscriminately imitate the suspension that has the vertical shaft sliding formwork now.
