Frost heaving resistance device for embankment project

Abstract

The invention discloses a frost heaving resistance device for an embankment project. The frost heaving resistance device comprises a sealing plate, the interior of the sealing plate is divided into at least four independent cavities through at least three supporting plates, and a steam generator is arranged at the bottom of the sealing plate. The side edge of a power assembly located at the right end of the steam generator is connected with an arc-shaped base plate through a waterproof piston. The left end of the steam generator is provided with a water inlet pipe, and an electromagnetic timing valve is arranged on the water inlet pipe. The upper end of the steam generator is connected with a steam conveying pipe, and steam conveying branch pipes identical with the independent cavities in number are arranged at the right end of the steam conveying pipe. The outer end of the sealing plate is painted with a layer of anti-freezing finishing coat. According to the frost heaving resistance device, by means of the double measures of heat generated by the underwater steam generator needing no manual power supplying and the anti-freezing finishing coat formed by scientific compatibility, freezing of a hydraulic construction structure in frost weather is well prevented, and the hydraulic construction is prevented from being damaged by frost heaving; in addition, the frost heaving resistance device is low in cost, small in power consumption and capable of being used for a long time.

Description

technical field [0001] The invention relates to a water conservancy protection device, in particular to an anti-frost heave device for embankment engineering, and belongs to the technical field of water conservancy engineering. Background technique [0002] Water utilization embankment is a kind of water conservancy project used to retain water, release water and discharge floods. In the severe winter in the north, it is common for static ice pressure to damage the embankment structure, resulting in water leakage and collapse of the embankment structure and failure of the gate to continue to operate normally. , leaving a huge security risk. [0003] At present, there are many methods to prevent ice swelling and damage of embankment buildings, such as the benzene board method, that is, laying a deformed benzene board on the water facing surface of the building to absorb the static ice pressure caused by ice swelling, but the benzene board needs to be used every year.

[0002] Water utilization dykes are a kind of water conservancy project used to retain water, release water and discharge floods. In the severe winter in the north, it is common for static ice pressure to damage the dam structures, resulting in leakage of dam structures and failure of the gates to continue normal use. , leaving a huge security risk

[0003] At present, there are many methods to prevent ice swelling and damage of embankment buildings, such as the benzene board method, that is, laying a deformed benzene board on the water facing surface of the building to absorb the static ice pressure caused by ice swelling, but the benzene board needs to be used every year. Replacement, the labor cost is relatively high; the other is the bubble blowing method, that is, the pipeline is erected below the water surface of the building, and compressed hot air or high water temperature is sprayed out of the water surface through a submersible pump to form a non-freezing water belt, but The disadvantage of this method is that this method will not change due to the amplitude of the water level, while the water level in general reservoirs, rivers and other reservoirs is not constant, and some changes will occur according to the rainy season or dry season and artificial use In general, the place where there is water will freeze, so the actual use effect is not ideal; in addition, there is a way to melt ice with heat pipes, that is, to add heat pipe anti-freezing devices in the gate panel or gate groove, and use electric heat to melt the ice , although the effect is good, but the power consumption is large and the cost is high
