Concrete construction joint construction technology

Abstract

The invention relates to a concrete construction joint construction technology which comprises the steps that S1, a scabbling device carries out scabbling treatment on the concrete surface of a construction joint, and the scabbling device comprises a transmission mechanism used for transmitting a second scabbling machine and a scabbling mechanism used for scabbling; S2, a cleaning device is used for flushing sundries in the construction joint, and a collecting mechanism is used for collecting the sundries; and S3, the flushed construction joint is poured, and a central control unit obtains the vibrating frequency of a vibrating machine according to the scabbling efficiency of the scabbling device to vibrate concrete poured in the construction joint. The central control unit is arranged, the central control unit obtains the weight of sundries through the collecting device, adjusts the scabbling efficiency of the scabbling device and adjusts the water pressure and the water spraying angle of the water spraying pipe so that scabbling treatment can meet the preset standard, and meanwhile, the vibration frequency is obtained through the scabbling efficiency so that construction joint concrete construction can meet the preset standard.

Description

technical field [0001] The invention relates to the field of concrete, in particular to a construction technique for concrete construction joints. Background technique [0002] In the process of concrete pouring, due to design requirements or construction needs to be poured in sections, the joints formed between the concrete poured first and later, because the concrete poured first exceeds the initial setting time, the gap between the concrete poured later and the concrete poured later There is a joint surface, the concrete aggregate is concentrated at the construction joint, the concrete is loose, the new and old concrete stubble is obvious, and water leaks along the gap. The laitance layer and bleeding layer are correspondingly thicker, and the treatment of construction joints is more difficult. The effect of scraping off the surface laitance or secondary vibration is not good, resulting in the thick and fine aggregate when the concrete is poured at the joint. Inhomogenei...

Problems solved by technology

[0004] For this reason, the present invention provides a concrete construction joint construction process, which can solve the problem that the vibrating frequency cannot be adjusted according to the chiseling efficiency, so that the construction effect of the construction joint concrete conforms to the preset standard
