Description
Technical Field
The invention relates to the technical field of building construction devices, in particular to a circulating pile cap forming machine.
Background
The pile cap is a construction facility used for preventing the head of the driven pile from being damaged, and is constructed on the top of the pile foundation after the pile foundation is constructed for 28d, so that the pile foundation is protected from being damaged in the detection process. In every pile foundation construction project, the detection work of the pile foundation must be done, wherein pile caps need to be done to two kinds of detection methods of high strain and compressive bearing capacity, so that the safety of the formal pile foundation in the test process is ensured, and the accuracy of the detection data is ensured.
According to the standard, the conventional pile cap adopts the steel casing as the circular template of the pile cap, after pile cap reinforcement and concrete pouring, gas cutting removal is carried out before detection, the steel quantity for the steel casing is large, and only waste can be done once in use, the quantity of project pile foundations is large, according to the standard sampling proportion, the quantity of the project required for the steel casing is large, so that the project detection cost is high, the construction period is long, meanwhile, the waste of a large amount of steel is caused, and the sustainable development concept of project construction period propulsion and green environmental protection is not facilitated.
In the construction process of the traditional pile cap, the pile cap generally adopts the following process flows: the method comprises the steps of impact drilling to break a pile head, pile head pulling out, pile foundation original steel bar straightening, welding, pile cap steel bar binding, steel casing sleeving, concrete pouring, casing gas welding cutting and detection of the reaching time to be detected.
And (3) impact drilling to break the pile head: section unevenness after the pile head is abolished often causes destruction (chisel absolutely) to the original reinforcing bar of pile foundation, leads to original chisel disconnected reinforcing bar to need the bar planting again, and unevenness's pile head cross-section appearance quality is poor, is unfavorable for pile cap to combine and testing result.
Pile head pulling out: the pile head of present technology is pulled out, and the pile head that will strike the brill and peel off is promoted, hoisted through the excavator, and the in-process can cause the pile head to turn on one's side, presses disconnected or press the curved circumference pile head reinforcing bar even, leads to planting the muscle again, and the chisel in the outside can not completely separate being connected of pile head and pile foundation, promotes, hoist the in-process at the excavator, can lead to the pile head center to have great lower limit or arch, can't carry out the pile foundation and detect or influence the accuracy that detects the data.
Sleeving a steel casing: firstly, after the steel casing is detected to be finished, gas cutting and cutting are needed, the steel consumption is large, and only waste can be generated after one-time use, so that the project detection cost is high, the construction period is long, meanwhile, a large amount of steel is wasted, and the project construction period is not facilitated to be promoted and the sustainable development concept of green and environment protection is not facilitated; secondly, the installation and leveling of the steel casing are completely dependent on manual impression, no guarantee measures are provided, and therefore after concrete pouring is completed, the detection surface of the pile cap is inclined, detection cannot be carried out or deviation influence is caused on detection data, and the detection period and the accuracy of the data are directly influenced.
The occurrence of various problems in the traditional process can cause long-time rework time, and greatly delay project construction period while influencing detection data.
