Abstract
The utility model discloses a check valve device of a pump pipe of a concrete delivery pump, which is characterized in that: the device comprises a concrete receiving pipe positioned on the bottom of a steel pipe column, a check valve plate and a pump pipe connecting pipe, wherein the check valve plate is fixedly connected between the concrete receiving pipe and the pump pipe, and the concrete receiving pipe is connected with the pump pipe by a specially-manufactured flange. The check valve plate mentioned in the utility model can ensure the concrete to pass smoothly when the concrete is being poured, effectively stops refluxing of the concrete after the concrete is poured, and is convenient for installation and construction, connected like a common concrete pump pipe on site and simple to operate.
Description
Technical field
The utility model relates to the anti-backflow field of pump line concrete of building site, relates in particular to a kind of concrete pump pump line check vavle device.
Background technique
Along with developing by leaps and bounds of building construction technology, the application of concrete filled steel tube is more and more, the casting method of steel core concrete column post core concrete has high throwing method and jack-block, jack-up construction technology is to utilize the pumping pressure of concrete pump that self-compacting concrete is poured into from the Steel Cylindrical Column bottom, until a kind of concrete without vibration method of construction of filling with whole Steel Cylindrical Column.For preventing that concrete refluxes when concrete delivery pipe is removed, need the backflow valve to be set in the column bottom, can prevent that just concrete from refluxing.
The model utility content
Technical problem to be solved in the utility model provides a kind of concrete pump pump line check vavle device, has solved concrete reflux problem when concrete delivery pipe is removed behind the steel core concrete column post core concrete casting complete.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
A kind of concrete pump pump line check vavle device is characterized in that: described device comprises that the concrete of Steel Cylindrical Column bottom inserts pipe, check valve plate, pump line connecting tube; Described check valve plate is fixedly connected on concrete and inserts between pipe and the pump line connecting tube; Described concrete inserts pipe and is connected by flange with the pump line connecting tube.
Check valve plate one end is provided with perforate consistent with Diameter of pump tube and bolt hole, and an end only is provided with bolt hole.
Described concrete inserts the steel pipe of Guan Weiyu pump line with diameter, one end and the welding of steel pipe bottom, and an end connects concrete and inserts pipe end flange.
Described pump line connecting tube one end is connected with pump line connecting tube end flange, and the other end is connected with the transfer pump pump line with flange.
Described two ends up and down with concrete access pipe flange connecting are equipped with outer bolt hole and inner bolt hole.
The utlity model has following advantage:
Check valve plate of the present utility model can guarantee that when concreting concrete passes through smoothly, builds and can effectively stop concrete backflow after finishing; Be convenient to installation, after the machine shaping, direct image normal concrete pump line equally connects at the scene, and is easy and simple to handle.Concrete reflux problem when the utility model has solved in the large diameter steel pipe post concreting preferably, guaranteed the degree of compaction of steel core concrete column post core concrete, thereby guarantee the integral construction quality of steel core concrete column, reduce concrete backflow waste simultaneously; Have simple and quickly, use manpower and material resources sparingly, characteristics such as fixed.

Embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in the figure, the 1-concrete inserts pipe, 2-check valve plate, 3-pump line connecting tube, the special flange of 4-concrete access pipe end, the common flange of 5-, and the 6-pump line connects the special flange of pipe end.
Check valve plate of the present utility model is fixedly connected on concrete and inserts between pipe and the pump line connecting tube; Described concrete inserts pipe and is connected by special flange with the pump line connecting tube.
Check valve plate one end is provided with perforate consistent with Diameter of pump tube and bolt hole, and an end only is provided with bolt hole.
Described concrete inserts the steel pipe of Guan Weiyu pump line with diameter, one end and the welding of steel pipe bottom, and an end connects special flange.
Described pump line connecting tube one end is connected with special flange, and an end is connected with the transfer pump pump line with common flange.
The two ends up and down of the described special flange that is connected with concrete access pipe are equipped with outer bolt hole and inner bolt hole.
As shown in the figure, build that end that perforate is arranged on the stage check valve plate and concrete insert pipe and the pump line connecting tube is fixed by special flange, use this moment the inner bolt hole of managing on the special flange that is connected to fix with the concrete access.Build and finish, remove two bolts up and down on the special flange, mobile check valve plate is fixed an end of no perforate on the check valve plate by the outer bolt hole on the special flange, and pump line is removed in the fixing back of check valve plate.
