Abstract
The utility model relates to a conveying pipe structure for pumping concrete downwards with a large gradient. At least one valve is arranged on a conveying pipe, at least two exhaust valves are arranged on the conveying pipe, at least one of the exhaust valves is arranged at one side of the valve between each valve and an inlet of the conveying pipe, and at least one of the exhaust valves is arranged at the position of the inlet of the conveying pipe. In the utility model, the concrete is deposited between the inlet of the conveying pipe and the valves by utilizing the valves arranged on the conveying pipe; meanwhile, air between the valves and the inlet of the conveying pipe is released by utilizing the exhaust valves arranged on the conveying pipe, so that the deposited concrete forms a dense cavity-free concrete column with a certain length; when the concrete is downwards pumped with the large gradient, a certain resistance is generated, and the occurrence of the phenomenon of pipe stoppage caused by the downward natural flow segregation of the concrete is prevented; and the distance of the valves away from the inlet of the conveying pipe and the number of the valves can be flexibly regulated according to an actual working condition, and the downward pumping of the concrete with the large gradient under various working conditions is realized. The utility model has simple and reasonable structure and convenient operation, can effectively guarantee the downward stable pumping of the concrete with the large gradient and can realize industrialized application.
Description
Technical field
The utility model discloses a kind of pipe structure of pumping of concrete, be meant the pipe structure of the downward pumping of concrete of a kind of heavy grade especially, belong to engineering machinery class concreting machinery technical field.
Background technology
In the concrete pumping machinery use, whether pipe structure is arranged is and an important link to be directly connected to pumpdown and can to carry out smoothly.General carrier pipe is arranged all standard, but far away in fed distance, drop is big up and down, and under the situation of transmission and concrete transmission side's amount little (also not coming out just to need pipe blow-through as the discharge end concrete), can its pumping just be difficult to guarantee smoothly.Because in these cases, there is following problem in the pumping process, one, conventional pipe structure, when downward pumping and angle of slope are spent greater than 7, need to be provided with the horizontal pipe of 5 times of drops or increase bend pipe etc. in the sloping transfer line lower end, but owing to environmental limit (as mine laneway), can't realize sometimes.Two, the pumping downwards and the gradient are big, and concrete makes to occur the cavity in the carrier pipe because of deadweight gravity flow downwards, concrete also can produce segregation, enter air in its pipeline and segregation back sandstone separates with cement paste, cause concrete flowability poor, resistance increases and causes plugging.Three, if the pumping side of each machine-team amount is little, as 3 cubes of concrete of a pumping and delivery tube more than 300 meters the time, calculate by theoretical, model is that side's amount of 125 the every 100m carrier pipe of carrier pipe inner concrete just has 1.22 cubes, pumping of concrete is not also filled carrier pipe to be about to begin and is washed pipe in such cases, causes pumping of concrete to be difficult to realize.
The utility model content
The purpose of this utility model be to overcome the deficiency of prior art and provide a kind of simple and reasonable, easy to operate, can ensure effectively that heavy grade stablizes the pipe structure of the downward pumping of concrete of heavy grade of pumping of concrete downwards.
The utility model is for solving the problems of the technologies described above, adopt following technical scheme: the pipe structure of the downward pumping of concrete of a kind of heavy grade, it is characterized in that: at least one valve is set on carrier pipe, at least two outlet valves are set on carrier pipe, at least one is arranged on described valve one side between described each valve and the described carrier pipe inlet described outlet valve, and at least one is arranged on described carrier pipe entrance described outlet valve.
In the utility model, described outlet valve is arranged on the upper surface of described carrier pipe.
In the utility model, described valve is a 120-150 rice apart from the minimum range of described carrier pipe inlet.
Operating principle of the present utility model and advantage are summarized as follows: at first, after the concrete that stirs enters from the carrier pipe inlet, utilization is arranged at the valve on the carrier pipe, concrete is stockpiled between carrier pipe inlet and described valve, simultaneously, utilization is arranged at the outlet valve on the carrier pipe, air between described valve and the carrier pipe inlet is discharged, make the concrete that accumulates form certain-length, closely knit, as not have cavity concrete column, make the downward pumping of concrete of heavy grade produce certain resistance, prevent that concrete from flowing automatically segregation downwards and the plugging phenomenon occurring; During pumping work, when outlet valve begins to emit concrete grout, close outlet valve, then, Open valve, accumulate in concrete column between valve and the carrier pipe inlet under the thrust of deadweight and concrete pump output, move forward automatically, realize the purpose of the downward pumping of concrete of heavy grade; Because the concrete column that the concrete that accumulates has formed is certain-length, closely knit, do not have the cavity, therefore, in follow-up pumping process, the phenomenon that can flow automatically and emanate has not guaranteed the stability and the reliability of the downward pumping of concrete of heavy grade.In addition, according to actual condition,, can adjust valve flexibly apart from the distance between the carrier pipe inlet and the quantity of valve, to realize the downward pumping of concrete of heavy grade under the various working as the pumping gradient, distance etc.
In sum, the utility model is simple and reasonable, easy to operate, can ensure effectively that heavy grade stablizes pumping of concrete downwards, can realize industrial applications.
