Adopt the inclined shaft pull of above-described inclined shaft sliding die body structure to climb the formula construction technology, may further comprise the steps:
Step 1, preparation;
(1), the borehole wall is handled; Wind successively should be cleared away or used to borehole wall dust before building concrete,, generally not adopt water to wash away for safety; The cavity of anchor spray is destroyed, made sliding formwork build concrete and spray concrete with anchor and combine closely, guarantee the concrete pouring quality; Inclined shaft center line unwrapping wire; According to borehole wall site specific, take corresponding measure, guarantee safe construction;
(2), try assembling, debugging before the sliding formwork assembling; Whether perfect in order to check the sliding mode system device of making after finishing, whether structure is reasonable, and whether processing adheres to specification, and the sliding formwork die body can be assembled and use smoothly, must carry out overall package and debugging on ground;
A, jack is organized into groups test;
Withstand voltage: pressurization 12Mpa, 5 minutes no seepage and no leakages;
Zero load is climbed: adjust stroke and be 25mm;
Load climbs: 5 tons of loadings of record are according to pole-climbing impression and stroke size, and the volume that impression is close with stroke is one group;
Standby, the spare part of jack: the work jack is 16, and reserve level is 1/3, i.e. the 5-6 platform.
Spare parts: block 50% up and down, big small pressure spring, oil extraction spring, big or small seal and snap ring each 20%.
B, sliding formwork assembling quality standard;
Assembling back sliding formwork die body should meet following quality requirement: template diameter design load 7500mm, deviation ± 2mm;
Port radius 7503mm ± 3mm on the template; Port radius 7500mm ± 3mm under the template;
Two-way verticality ± the 2mm of hoisting frame; Hoisting frame left and right sides position 20mm; Hoisting frame front and back position 5mm;
Jack floor level degree ± 2mm; Jack axis verticality: do not allow;
Adjacent forms planeness ± 0.5mm.
Step 3, in the enclosure of adjacent sliding formwork monomer mounting template;
The pumping concrete mode of putting in storage is adopted in step 5, concrete blanking; During pour concrete, adopt layer-by-layer casting from low to high, every cast one deck checks whether the center line of inclined shaft sliding die body structure departs from the inclined shaft central axis;
Build for the first time the concrete or the mortar of thick half aggregate of 10cm, then build the second layer by layering 30cm, when thickness reaches 70cm, check whether the sliding formwork die body has the inclined shaft of departing from central axis, the 4th layer of normal after-pouring, build 1m for the 4th layer, continue to check and build layer 5, layer 5 is built 1m, continues to check and builds layer 6, until building be 0.3 meter suitable for reading away from sliding formwork die body, beginning is just sliding.
When building each layer,, build again after must adjusting, reinforce sliding formwork die body structure if sliding formwork die body structure centre line has the inclined shaft of departing from central axis phenomenon;
In order to guarantee that concrete puts in storage smoothly, require the concrete workability good, the slump is controlled at about 15～17cm.
Construction changes normal the cunning when rising over to, should keep continuous construction as far as possible, and establishes special messenger's observation and analyze the concrete surface condition, determines suitable sliding the liter time; The concrete of the demoulding does not have trickling and drawing crack phenomenon, and hand is by there being hard sensation, and can reserve the finger mark about 1mm, and is can the usefulness trowel floating; The sliding formwork concrete is required solid 8 to 10 hours body initial setting times, and so-called solid body initial set is not reach initial set but do not trickle, and promptly hand is by there being 1mm to refer to trace, the pressure about about 0.1Mpa.
According to the site operation situation, determine the rational sliding speed of sliding formwork die body, by normal sliding the liter each 1 hour at interval, the sliding rise of control 30cm/ time, a day sliding rise is controlled at about 3 meters.
Having a shave is one important procedure of sliding formwork concrete, must carry out this work immediately after the concrete demoulding, generally flattens or repairs with magma on the concrete surface with trowel.
Measure control: the sliding formwork die body rises in the process sliding, be subjected to various inhomogeneous dynamic effects, drift condition can take place in the sliding formwork die body, for convenience, observe the skew of sliding formwork die body in time, establish three three parallel lines that are parallel to the inclined shaft central axis in enclosure inboard (trisection), observe the initial position of enclosure, in time rectify a deviation parallel lines; The every segment length of parallel lines is not more than 20 meters.
External force correction: utilize borehole wall dowel to use and lead chain tractive die body, apply foreign compulsion die body (rotation) displacement, reach the correction purpose; Or at top spacing 1.5m two No. 16 channel-section steels are installed along the inclined shaft axis direction and are made track, form the rail sliding formwork.
Self rectifies a deviation: by adjusting the jack discrepancy in elevation, the work card of making has the generation discrepancy in elevation of corresponding purpose, self rectifies a deviation gradually sliding the liter in the process.
The correction of self and external force: when deviation (or rotation) was big, two kinds of methods and usefulness reached the correction purpose.
Labor organization and duration
1, labor organization: adopt two classes of 12 hours operating types, program manager 1 people, chief technology officer 1 people, footman assistant manager 2 * 1 people, footman technician 2 * 1 people, footman squad leader 2 * 1 people, bar bender 2 * 10 people, concrete worker 2 * 7 people, electrician 2 * 1 people, electric welder 2 * 1 people, maintenance 2 * 2 people have a shave, sliding formwork is safeguarded worker 2 * 2 people, and general labourer 2 * 4 people add up to: 62 people;
2, the construction period: die body is made 10 days (making can not account for the straight line duration), and die body was installed 7 days, and 20 days (every day is by 3 meters) of sliding liter are removed and had bad luck 5 days, count 32 days.
Should be noted that at last: the actual sliding time that rises is only used 11 days.
Above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present invention; And not breaking away from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope that the present invention asks for protection.
