An automatic deflation device for brine dry pipe

Abstract

The invention discloses a salt water main pipe automatic deflating device and belongs to the field of freezing method construction technological machines. The salt water main pipe automatic deflatingdevice comprises two connecting pipes arranged on a salt water main pipe, a guiding rod, a telescopic rod, a deflating switch and a floating block, wherein the deflating switch and the floating blockare arranged on the guiding rod. The ends, away from the salt water main pipe, of the two connecting pipes are connected with a guiding rod, a deflating pipe penetrating through the guiding pipe is arranged on the guiding pipe, and a cut-off valve is arranged on the deflating pipe. The guiding rod is connected to the cut-off valve, a baffle is arranged on the position, corresponding to the deflating switch, in the guiding pipe, and a gap for allowing salt water to pass through is formed between the lower edge of the baffle and the inner wall of the guiding pipe. According to the salt water main pipe automatic deflating device, through the floating block, by means of the buoyancy effect, the deflating switch is touched, automatic control is achieved, manpower interference is not needed, theoperation difficulty is reduced, the manpower burden is reduced, control is more accurate and more timely, and the time and construction costs are saved.

Description

technical field [0001] The invention relates to a freezing method construction technology device, which belongs to the field of freezing method construction technology machinery, in particular to an automatic deflation device for a salt water dry pipe. Background technique [0002] Artificial ground freezing method sinking technology is an ideal special sinking method in the case of coal mine shafts passing through layers with thick topsoil and many aquifers in my country. Since 1955, when the westerly shafts of Linxi Mine in Kailuan were constructed using the freezing method for the first time, more than 700 vertical shaft shafts have been constructed, and the cumulative length of frozen shaft shafts has reached 150 km, which has been widely used. Artificial ground freezing technology began in the 19th century, based on the research on the physical and mechanical properties of permafrost under natural freezing conditions, and gradually developed with artificial freezing and...

Problems solved by technology

[0004] The traditional method is time-consuming and laborious. In view of this problem, it is very necessary to research and invent an automatic deflation device for brine mains to assist deflation, which can not only save construction cost and time cost, but also ensure the safe and smooth construction of the freezing method.
