Description
Technical field
The present invention relates to the method for construction of a kind of high pressure shaft tower, belong to technical field of electric power.
Background technology
In high pressure stem tower foundation is constructed, owing to high pressure stem column foot hole is single hole, and foundation bolt is big from weight, uses tradition side
When method carries out foundation construction, column sinks serious, and foundation bolt is difficult to centering.Instruct accordingly, it would be desirable to work out new construction method
Construction.
Summary of the invention
According to above-mentioned requirements, it is an object of the invention to provide the method for construction of a kind of high pressure shaft tower, to ensure the centering of foundation bolt.
For achieving the above object and other relevant purposes, the present invention provides below scheme:
The method of construction of a kind of high pressure shaft tower, comprises the following steps:
A. repetition measurement location:
Before foundation excavation, it is necessary to check the position at the shaft tower center that nail is vertical when design is surveyed eventually according to construction drawing；The most also tackle quilt
Cross over or pass through the most inadequate landform raised points of thing, wire distance to the ground and leap thing that the whole oversight of design is surveyed and important disconnected
Cake carries out repetition measurement and mends survey, final confirmation shaft tower center；
B. earthwork evacuation:
For hard soil and powdery loess step excavation formula foundation pit, controlling base plate of foundation pit width well, foundation depth is in strict accordance with construction
Figure is constructed；For phenomenon of backbreaking, dig part more and answer paver grouting treatment；For the foundation pit that level of ground water is higher, construction
Time configuration pumping equipment extract hole internal water accumulation out, and add the gradient of hollow place wall；
During excavation of foundation pit, monitoring foundation ditch position and shape at any time, foundation ditch excavates and should carry out in time close to when cheating deep size
Hole is deep to be measured, and carries out Leveling and centering after foundation ditch molding；
C. reinforcing bar binding and basis formwork:
Reinforcing bar binding: before reinforcing bar binding, first has to check specification and the quantity of reinforcing bar, completely the same with construction drawing；In order to
Ensure that the spacing of each position reinforcing bar meets design requirement, according to spacing and the present position of reinforcing bar, reinforcing bar is finished with crayon and ties up
Prick labelling；The application iron wire colligation of reinforcing bar cross point is firm；
Basis formwork includes that bed die and step mould, bed die and stepped formwork use integral forming steel form, and each layer template installs additional respectively
Enclose stupefied, template the most first brush interleaving agent, prevent interleaving agent from gluing, drip on reinforcing bar；Due to casting concrete be at column and
Under the weight effect of concrete, ground floor, second layer step medial surface template stress are relatively big, therefore, must enter it during construction
Row is reinforced, and prevents deformation；
Bed die and the concrete mats pier liner of step mould support bed die height or support with the stupefied each angle of ∠ 125 × 10 angle steel torr, press
After assigned position supports, the relevant position cement mortar at the end, hole is fixed, and upright supports angle steel torr is stupefied；In order to prevent column
The pressure that template is big sinks with model of the column on bed die and step die shoe are stupefied, each for model of the column angle guide chain will be hung to hole respectively
Mouthful the most mounted the most stupefied on；
D., model of the column is installed:
Model of the column is arranged on second layer stepped formwork by angle steel torr is stupefied, model of the column by adjustable apical organ in foundation pit walls
Upper enforcement；Model of the column torr is stupefied to be arranged on stepped formwork, owing to model of the column is higher, heavier, in order to prevent model of the column
Sink, affect construction quality and the end face discrepancy in elevation, need column template to carry out
Promote and reinforcement；
E. the laying of foundation bolt:
Before and after on the horizontal, vertical line direction of foundation bolt, two bolt pitch carry out mark with red pen, and vertically become one
Straight line；This labelling to shift to an earlier date ready-made labelling point-blank on model of the column；
F. the measurement of integral basis foundation torsion: if integral basis foundation torsion meets design requirement, then proceed to next step；As do not met,
Above-mentioned steps a, b, c, d and e are modified；
G. foundation concrete is cast:
Before basis is cast, to the check for the first time of detection ruler little progress row；Basis is monitored during casting；Concrete casts lower margin spiral shell
During bolt extension position, to the second time check of detection ruler little progress row；After each basis has been cast, carry out third time size check；
Through repeated detection, key dimension can be controlled and meet the requirements；Then carry out foundation concrete to cast；
H. foundation ditch backfill:
Use soil or husky backfill that former hole digs out, should often backfill certain thickness watering compacting during backfill once；
The auxiliary pile quantity of described point of hole step conclusion is more than 6 on horizontal, vertical circuit.
Preferably, described reinforcing bar binding step, when assembling reinforcement cross point, when colligation muscle is in Φ less than 12, double with 22#
Stock wiring colligation is together；When colligation muscle is in Φ more than 12, by 22# bifilar wiring decussation colligation twice.
Preferably, described basis formwork step in, each for model of the column angle is hung respectively near coal-mine the most mounted the most stupefied on lead
