Circulating pile cap former

Abstract

The invention provides a circulating type pile cap forming device which comprises a pile casing body, the pile casing body comprises two semicircular wall bodies, one sides of the two semicircular wall bodies are connected in a hinged mode, and one semicircular wall body rotates around one side of the other semicircular wall body so that the two semicircular wall bodies can define the pile casing body; the semicircular wall body is also provided with a detection hole, and the inner wall of the semicircular wall body is also provided with a covering piece for covering the detection hole; the connecting assembly is used for enabling the other sides of the two semicircular wall bodies to be detachably connected; and the inner walls of the two semicircular wall bodies are coated with the release agent layers. The pile casing body is formed by the two semicircular wall bodies in a detachable mode, the pile casing body can be dismantled after a pile cap is formed, cyclic utilization is facilitated, production cost is saved, and construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of building construction devices, in particular to a circulating pile cap former. Background technique [0002] The pile cap is a construction facility used to prevent the pile head from being damaged. After 28 days of pile foundation construction, it is finally constructed on the top of the pile foundation to protect the pile foundation from being damaged during the inspection process. In every pile foundation construction project, it is necessary to do pile foundation detection work, and the two detection methods of high strain and compressive bearing capacity need to be pile caps to ensure the safety of the formal pile foundation during the test process and guarantee Check the accuracy of the data. [0003] According to the specification, the conventional pile cap is a round formwork using a steel casing as the pile cap. After the pile cap reinforcement is bound and the concrete is poured, gas cutting is...

Problems solved by technology

[0005] Impact drilling to break the pile head: After the pile head is broken, the section is uneven, which often causes damage to the original steel bars of the pile foundation (chisel off), resulting in the original chiseled steel bars Rebar needs to be replanted, and the appearance quality of the uneven pile head section is poor, which is not conducive to the combination of pile caps and test results

[0006] Pile head extraction: The current process of pile head extraction involves lifting and hoisting the pile head stripped by the impact drill through an excavator. During the process, the pile head will roll over, or even break or bend the circumferential pile head steel bar, resulting in re-planting the bar. Moreover, the chiseling on the outside cannot completely separate the connection between the pile head and the pile foundation. During the lifting and hoisting process of the excavator, there will be a large lower limit or protrusion in the center of the pile head, which will make it impossible to detect the pile foundation or affect the accuracy of the detection data.

[0007]Steel casing: First, the steel casing needs to be cut off by gas cutting after the inspection, which requires a large amount of steel and can only be discarded after one use, resulting in The cost of project inspection is high, the construction period is long, and it also causes a lot of waste of steel, which is not conducive to the advancement of the project construction period and the sustainable development concept of green environmental protection; second, the installation and leveling of the steel casing are all based on manual perception , there are no safeguards, resulting in that after the concrete pouring is completed, the detection surface of the pile cap is inclined, which makes it impossible to detect or cause deviations to the detection data, directly affecting the detection period and the accuracy of the data

[0008]The emergence of various problems in the traditional process will cause a long time for rework, which will greatly delay the project duration while affecting the test data
