Device and process for removing water bubbles on side surfaces of segments

Abstract

The invention provides a device and process for removing water bubbles on side surfaces of segments. The device comprises a high-pressure sealing barrel, a water inlet pipeline, a water outlet pipeline, a heater, an atomizing nozzle, an oscillator and an air pump, wherein the air pump communicates with the high-pressure sealing barrel, one end of the water inlet pipeline communicates with the high-pressure sealing barrel and is provided with the atomizing nozzle, the atomizing nozzle is connected with the oscillator, and the heater is arranged on the water inlet pipeline, and the high-pressuresealing barrel communicates with the water outlet pipeline. By the device for removing the water bubbles, at the beginning of concrete pouring, generation of the water bubbles accumulated on the sidesurfaces is avoided, an effect of removing the water bubbles during construction is achieved, traditional secondary vibration and a process of inserting a thin iron sheet for guiding and dischargingare omitted, the device is convenient to use and operate, and the effect of the device is better than that of a traditional mode.

Description

technical field [0001] The invention relates to a concrete construction technology, in particular to a device and a technology for removing water bubbles on the side of a segment. Background technique [0002] Concrete segments are used as the main lining structure during construction, and surface cracks and water bubbles are more likely to be generated during the production process of segments. These water bubbles mostly appear on the side of the segment and near the water stop, especially at the top of the arc-shaped water stop of the segment. Although there is no great danger to the segment at the beginning, as the age of the concrete increases, the external load and Repeated action under external temperature changes, these small air bubbles will affect the time period of the service life of the segment, and also weaken the thickness of the local protective layer, which has a certain impact on the quality of the segment. As long as corresponding measures are implemented, ...

AI Technical Summary

Problems solved by technology

[0004] The existing method of discharging water bubbles has certain disadvantages when used. The thin iron sheet is used for drainage. Due to careless operation, the thin iron sheet will scratch the outer arc surface of the side of the tube. At the same time, add a water reducer The prices on the market vary and there are many types, so it is difficult to choose comparatively, and it is also difficult to grasp the time and operation process of the second vibration

Unable to meet the needs of the existing process flow, which will have a certain impact on the operation
