Embodiment 1
[0054] see figure 1 , the low porosity grouting process of concrete pouring, comprising the following steps:
[0055] S1, see figure 2 , first make the pouring formwork, and then install the micro-seismic air column longitudinally in the middle of the pouring formwork;
[0056] S2. Install inflatable pinballs at the end of the micro-vibration air column protruding from the formwork;
[0057] S3. Pouring concrete slurry into the formwork from above the formwork, and vibrating;
[0058] S4. Afterwards, the inflatable pinball is repeatedly pressed repeatedly, and the gas inside the inflatable pinball enters into the micro-vibration air column, thereby driving the concrete slurry to vibrate slightly from the inside;
[0059] S5. After a period of time, remove the inflated pinball, and inject pre-solidified powder into the micro-vibration air column along the upper port of the micro-vibration air column;
[0060] S6. Seal the upper end of the micro-seismic gas column, perform ...

Abstract
The invention discloses a low voidage grouting process of concrete pouring, and belongs to the field of concrete pouring. According to the low voidage grouting process of concrete pouring, a micro-vibration air column is arranged in a mold plate; after grouting, an inflated ball is squeezed to transfer the position of inert gas inside the pinball, so the micro-vibration air column continuously generates outward expansion vibration and the location of a micro-vibration rod is continuously moved; therefore, surrounding concrete slurry can be effectively loosened, the porosity volume inside the micro-vibration air column can be effectively lowered, and the strength and quality of concrete is significantly improved; and at the same time, pre-solidified powder is injected into the inside of themicro-vibration air column after grouting, so on the one hand, voids in the micro-vibration air column can be effectively filled and influence of the voids on a concrete prefabricated member is effectively avoided, and on the other hand, an operator can open a sealed opening part of the micro-vibration air column to detect the phenomenon of the pre-solidified powder so as to judge the water seepage condition of the concrete prefabricated member, so timely maintenance is convenient and safety is improved.
Description
technical field [0001] The invention relates to the field of concrete pouring, more specifically, to a low-voidity grouting process for concrete pouring. Background technique [0002] Ordinary concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in an appropriate proportion, and uniformly stirred, compacted and cured. . Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, that is, fresh concrete or concrete mixture; the hard state after hardening, that is, hardened concrete or concrete. The strength grade of concrete is divided by the standard value of cubic compressive strength. The strength grade of ordinary concrete in China is divided into 14 grades: C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75 and C80 . [0003] Generalized concrete is an artificial stone made of ceme...
