Pile crown reinforcing bar must arrange straight, and integral position is not eccentric, and top packages Reinforced Hoop rib ring and secured.
(2) pier shaft main reinforcement is processed, pier shaft main reinforcement bottom is bent by design, so as to the connection of same stake top reinforcing bar, Reinforced Hoop
Rib ring is made into circular ring shape, and diameter is reasonable, and weld is secured.Common stirrup processing and fabricating is good, and connector is not connected to, to put on pier
Body main reinforcement.
(3) the small springboard (being supported in Reinforced Hoop rib ring, as stirrup operation platform above) constructed upwards is got out.
(4) preparation of pier shaft main reinforcement and pile crown bar splicing, fixation is performed.
(5) training for manually holding up single pier shaft main reinforcement is performed, determines that the rigidity after pier shaft main reinforcement erects whether there is and asks
Topic, and determine the method for guaranteeing that pier shaft main reinforcement is vertical.
(6) Reinforced Hoop rib ring is put
In order to reinforce the overall stiffness of pier shaft main reinforcement, pier shaft main reinforcement is generally provided with reinforcement stirrup in design, reinforces stirrup
The usually spiral of diameter 20mm or more, strength and stiffness with higher.
The Reinforced Hoop rib ring for all pier shafts made neatly is overlayed on the Reinforced Hoop rib ring of pile crown top, this is
The key link of this engineering method solves the problems, such as being inserted in for Reinforced Hoop rib ring.If Reinforced Hoop rib ring spacing is larger, it is unfavorable for subsequent
Artificial merogenesis operation, can suitably increase Reinforced Hoop rib ring, reduce strong stirrup circle spacing.
(7) it erects pier shaft main reinforcement and is connect with stake top reinforcing bar
It manually holds up the pier shaft main reinforcement made is single, is deep into the pier of the Reinforced Hoop rib ring and stake top position that place
Body main reinforcement inside and drilled pile main reinforcement firm welding (using spot welding).All pier shaft main reinforcements and drilled pile reinforcing bar are completed according to this
Connection and fixation.If pier shaft main reinforcement bottom, which is bent with deviation, should carry out appropriate adjustment, have to guarantee that pier shaft main reinforcement is erect
Vertically.
(8) strong stirrup and fixation are lifted up
After all pier shaft main reinforcements connect and are in plumbness, it is lifted up all Reinforced Hoop rib rings；It can be step by step
It carries out, until bottom Reinforced Hoop rib ring to design position, nethermost Reinforced Hoop rib ring and pier shaft main reinforcement is fixed into (binding)
Securely, reach the degree that construction can be continued up as support.In the process, other can be added for the ease of operation
Strong stirrup circle is fixed temporarily.
(9) thin stirrup is bound
This intersegmental thin stirrup is secured by design spacing binding.
(10) continue next segmental construction, until completing
It is support with the first segment Reinforced Hoop rib ring that state sets, puts small springboard above it as platform, press
Next segmental construction is carried out according to the step of (8), (9), until the construction of top Reinforced Hoop rib ring finishes, is carried out down after inspecting for acceptance
The construction of one step.
Relatively narrow thicker plank can be used by being supported on the small springboard reinforced on stirrup, it is also possible to which fashioned iron etc. has to fix
Securely.
Material is reinforcing bar, steel plate, spring steel plate.
Quality control
(1) quality control standard
" highway bridge and culvert construction technology construction technique normalizing " (JTGT F50-2011)
" Road Engineering Quality Checking And Evaluation standard " (JTG F-80/1-2012)
(2) the quality control in work progress
1. reinforcing bar and steel plate should test before, the processable production in qualified rear.
2. pier shaft main reinforcement lower part is bent by design size and angle, precise control of angular degree so that pier shaft main reinforcement with
Plumbness is in after the connection of bored concrete pile main reinforcement.And pier shaft main reinforcement has to be connected firmly with bored concrete pile main reinforcement.
3. reinforcing bar is centainly careful not to destroy pier shaft main reinforcement when connecting, pier shaft main reinforcement intensity is reduced；The binding of thin stirrup
It is secured when than commonsense method construction；
4. paying attention to guaranteeing the spacing of Reinforced Hoop rib ring and thin stirrup.
Safety measure
(1) Ying Zunzhao People's Republic of China (PRC) industry current standard " highway engineering construction act of technique for security " and " highway
Terms security evaluation guide " requirement carry out.
(2) technical measures of construction safety scheme should be formulated according to operation, and strictly acted in accordance with it.
(3) construction site operating personnel answers hard hat required at all times, should highly fasten seat belts more than constructing operation personnel after 2m.
