Description
Technical field
The utility model is related to a kind of tunnel arch wall concreting mechanisms.
Background technology
Tunnel arch wall concrete in casting process, due to concrete free-falling excessive height can cause concrete from
Analysis influences the pouring quality of concrete, it is therefore desirable to which with sliding slot come delivering concrete, and common concrete sliding slot is mutually only
It is vertical, it is impossible to meet the requirement that each window can be fed.
Utility model content
The shortcomings that in order to overcome the prior art and deficiency, the utility model discloses a kind of tunnel arch wall concrete casting machines
Structure, including separatory funnel, plugging plate and discharge nozzle；The separatory funnel is provided with multiple discharging windows, and the discharge nozzle is from institute
The outside for stating separatory funnel is connected with the discharging window；The plugging plate is arranged in the separatory funnel, the plugging plate
The discharging window can be opened or closed.
Further, delivery pipe and three-way connection, one end of the discharge nozzle and one end of the three-way connection are further included
Connection, other both ends of the three-way connection are respectively connected with delivery pipe.
Further, the side of the separatory funnel is inverted trapezoidal, and the width of the separatory funnel gradually subtracts from top to bottom
It is small.
Further, the discharging window inner wall is provided with internal thread, and one end outer wall of the discharge nozzle is provided with outer spiral shell
Line, the internal thread cooperate with external screw thread and connect.
Further, the plugging plate includes plate body and the boss being arranged on the plate body, and the boss is inserted into
In the discharge nozzle.
Further, the boss is annular convex platform.
Further, the diameter of the annular convex platform gradually increases from inside to outside.
Further, the outer wall of the boss is provided with elastic swelling layer.
Further, the plugging plate further includes the handle being arranged on the plate body.
Further, the outer wall of the separatory funnel is provided with hangers.
A kind of tunnel arch wall concreting mechanism of the utility model can preferably adjust concrete in filling process
Flow direction, reaching each window has concrete warehouse entry, and also allow for control concrete free-falling height, the arch wall poured
Concrete quality appearance is preferable, and concrete inner structure is uniform.
In order to better understand and implement, the utility model is described in detail below in conjunction with the accompanying drawings.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Fig. 2 is the schematic diagram of plugging plate.
Specific embodiment
It please refers to Fig.1 with 2, the utility model discloses a kind of tunnel arch wall concreting mechanism, including separatory funnel
10th, plugging plate 20, discharge nozzle 30, delivery pipe 40 and three-way connection 50；The separatory funnel 10 is provided with multiple discharging windows
11, the discharge nozzle 30 is connected from the outside of the separatory funnel 10 with the discharging window 11；The plugging plate 20 is arranged on
In the separatory funnel 10, the plugging plate 20 can open or close the discharging window 11.One end of the discharge nozzle 30 with
One end connection of the three-way connection 50, other both ends of the three-way connection 50 are respectively connected with delivery pipe 40.The sub-material leakage
The side of bucket 10 is inverted trapezoidal, and the width of the separatory funnel 10 is gradually reduced from top to bottom.
Discharging 11 inner wall of window is provided with internal thread, and one end outer wall of the discharge nozzle 30 is provided with external screw thread, institute
Internal thread is stated to connect with external screw thread mutual cooperation.The plugging plate 20 includes plate body 21 and the boss being arranged on the plate body 21
22, the boss 22 is inserted into the discharge nozzle 30.The boss 22 is annular convex platform 22.The annular convex platform 22
Diameter gradually increases from inside to outside.The outer wall of the boss 22 is provided with elastic swelling layer 221.The plugging plate 20, which further includes, to be set
Put the handle 23 on the plate body 21.The outer wall of the separatory funnel 10 is provided with hangers 12.By the boss 22 of plugging plate 20
When being caught in delivery pipe 40, elastic swelling layer 221 is compressed, and so as to hold out against the inner wall of the delivery pipe 40, ensures sealing.It hangs
The setting of ear 12, which is available for users to, fixes separatory funnel 10.
Mechanism divides storehouse blanking for tunnel arch wall concrete, and the discharge nozzle 30 and delivery pipe 40 are steel pipe, other
PE can also be used to manage in embodiment.Discharge nozzle 30 and delivery pipe 40 are linked together by the three-way connection 50, are fixed on
On trolley.Separatory funnel 10 is welded using steel plate, the closed windows that will need not be perfused using plugging plate 20 when in use,
Mechanism combination ground pump perfusion arch wall concrete divides storehouse blanking effect preferable.
A kind of tunnel arch wall concreting mechanism of the utility model can preferably adjust concrete in filling process
Flow direction, reaching each window has concrete warehouse entry, and also allow for control concrete free-falling height, the arch wall poured
Concrete quality appearance is preferable, and concrete inner structure is uniform.
