The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is made a detailed explanation.
As shown in Figure 1, the present embodiment provides a kind of large volume immersed tube to build the construction method of reinforcing cage, comprises the following steps:
Step 001: processing district and semiproduct are stacked; Base plate and top board reinforcing bar processing capacity large (accounting for than weighing more than 81%), reinforcing bar is stacked and is concentrated on base plate storage area and top board storage area; The relatively less and region that mediates of side wall reinforcing bar amount, therefore be arranged in this zone line by reinforcing bar sawing machine, die head threading machine and flatting bending machine; Steel Reinforcing Bar Material and mantle fiber concentrate on this zone line processing, bending machining is distributed in each region, straddle carrier and ferry bus are set and carry out reinforcing bar conveying, each colligation pedestal district all arranges corresponding reinforcing bar semiproduct laydown area, for guaranteeing construction efficiency and professional, reinforcing bar processing and the operation of installation colligation personnel grouping cooperative, not mixture operation.
Step 002: reinforcing bar subregion colligation; On reinforcing bar binding production line, use portable chassis, on base plate steel bar binding pedestal, side wall reinforcing bar binding pedestal and the top board reinforcing bar binding pedestal being provided with at portable chassis, carry out the reinforcing bar binding of immersed tube sections simultaneously; Reinforcing bar is divided into base plate, body of wall, three colligation districts of top board, and work is carried out in three operation areas simultaneously, and at utmost reinforcing bar binding speed is improved in Shangdi.
Step 003: reinforcing bar subregion pushing tow; First by base plate steel bar binding pedestal, side wall reinforcing bar binding pedestal and top board reinforcing bar binding pedestal on portable chassis described in the base plate thrustor on reinforcing bar binding production line, side wall thrustor and the corresponding synchronous push of top board thrustor to building station.The present embodiment also can be monitored by pushing tow control system the synchronous push operation of described base plate thrustor, side wall thrustor and top board thrustor.And, by hydraulic jack, respectively described base plate thrustor, side wall thrustor and top board thrustor are driven.And pushing tow control system is specifically monitored base plate thrustor, side wall thrustor and top board thrustor by following steps:
3a) by oil cylinder working-pressure sensor, the oil pressure induced signal obtaining from described base plate thrustor, side wall thrustor and top board thrustor is sent to the master controller of pushing tow control system, by oil cylinder stroke sensor, the stroke induced signal obtaining from described base plate thrustor, side wall thrustor and top board thrustor is sent to described master controller simultaneously;
3b) described master controller, by oil pressure and the stroke induced signal received, is controlled in real time oil cylinder working-pressure and stroke separately on described base plate thrustor, side wall thrustor and top board thrustor, thereby is made them complete synchronous push operation.
As shown in Figure 2, described pushing tow control system comprises master controller 1, pumping plant sub-controller 2, oil cylinder stroke sensor 3 and oil cylinder working-pressure sensor 4, described oil cylinder stroke sensor 3 is connected 7 with described base plate thrustor 5, side wall thrustor 6 and top board thrustor respectively, and described oil cylinder working-pressure sensor 4 is connected with described base plate thrustor 5, side wall thrustor 6 and top board thrustor 7 respectively, and oil cylinder stroke sensor 3 and oil cylinder working-pressure sensor 4 send induced signal to master controller 1 respectively.Master controller 1 is by the signal of collecting, to pumping plant sub-controller 2, send instruction, thereby control stroke and the oil pressure of base plate thrustor 5, side wall thrustor 6 and top board thrustor 7, three pedestals that synchronous push reinforcing cage is built have been reached, can be by automatic, manual and sequence mode control master controller 1, the synchronous push construction of realization to reinforcing cage, and all pushing tow state parameters are monitored in real time, the pushing tow operation of reinforcing cage effectively, fast and stably controlled.
Step 004: reinforcing cage system conversion; Reinforcing cage incremental launching device by reinforcing cage by sliding rail integral pushing to building station, by displacement air bag jack-up reinforcing cage, withdraw from sliding rail, remove after displacement air bag reinforcing cage and transfer to and on the bed die of building station, complete stressed conversion.The every each configuration 1 cover displacement gas capsule of production line, because reinforcing cage is flexible structure, be out of shape larger, this displacement air bag equidistant placement has many, preferably 12, ultimate range between every two displacement air bags is about 4.4m, calculates the distortion of reinforcing cage, and effective rising height of air bag must be greater than maximum defluxion.The top of this displacement air bag is provided with air bag backing plate, and this air bag backing plate mainly can be comprised of 10mm steel plate and the thick core-board of 3mm, by the combination of steel plate and plank, has both reduced the quality of air bag backing plate, has also improved the toughness of air bag backing plate.In addition, before installation displacement air bag, should first remove burr, prevent from replacing air bag gas leakage.
Above embodiment is only for illustrating the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
