It is located at the top of drilling platform to the top of next section steel reinforcement cage;
Step 4: step 3 is constantly repeated, until the decentralization of final section steel reinforcement cage is completed.
In the method, descending frame is used, the mode that upper section steel reinforcement cage is fixedly connected with drilling platform is existing skill
Any one in art.
In the pay-off method of the steel reinforcement cage, by upper section steel reinforcement cage and drilled in the step 3 by shelving unit
Platform is fixedly connected, wherein the shelving unit includes:
It beats and sends disk, be cylinder-shaped, described beat sends disk to be laid on drilling platform, and described beat sends the inside of disk and stake holes phase
It is right;
Steel pile casting is arranged in the inside beaten and send disk, and is inserted into the stake holes, the height at the top of the steel pile casting
Degree beats the height for sending the top of disk described in being higher than;
Muti-piece stiffener, the circumferential direction interval setting of steel pile casting described in ring, and be located at and described beat the top for sending disk, institute
It states stiffener to be arranged along the vertical direction, one end on the stiffener along its length and the lateral wall of the steel pile casting are removable
Connect with unloading, the other end on the stiffener along its length with it is described beat send disk top side detachable connect;
Muti-piece snap-gauge, the circumferential direction interval setting of steel pile casting described in ring, the snap-gauge is arranged along the vertical direction, and position
With the top side detachable of the steel pile casting connect in one end on the top of the steel pile casting, the snap-gauge along its length
It connects, the other end on the snap-gauge along its length is opposite with the inside of the steel pile casting;
The pay-off method of steel reinforcement cage, comprising the following steps:
Step 1: four columns are fixed on drilling platform, pile foundation steel pile casting is made to be located at the region that four columns surround
Lower section;Install descending frame and shelving unit.
Step 2: removing all snap-gauges, head section steel reinforcement cage is transported in pile foundation steel pile casting by crane, and make first section reinforcing bar
The top of cage is located at the top of drilling platform;
Step 3: the other end on each snap-gauge along its length is inserted into upper section steel reinforcement cage, and make on snap-gauge
It connects to the top side detachable of one end and steel pile casting along its length, crane hook is released later, by next section steel reinforcement cage
It is transported to by crane in the region that four columns, four upper beams and four lower beams surround, to next section steel reinforcement cage and upper one
After the completion of the main reinforcement connection for saving steel reinforcement cage, two movable pulleys are connect with next section steel reinforcement cage, next section muscle cage is promoted later, takes
Snap-gauge out, then transfer the top that next section steel reinforcement cage is located at drilling platform to the top of next section steel reinforcement cage;
