[0017] The technical solution of the utility model is clearly and completely described below in conjunction with the drawings and specific implementation methods of the specification. The described embodiment is one embodiment of the utility model, and the utility model may also have other implementation methods.

[0018] Example:

[0019] See also Figure 1~Figure 4 The utility model discloses a chute device for concrete encapsulation of municipal pipelines, comprising a plurality of standard section chutes 1 connected in sequence; the standard section chute 1 has a U-shaped cross section and a plurality of protruding speed reduction bumps 2 are arranged at the bottom thereof.

[0020] In this embodiment, the chute device further includes a latch; through holes are opened at the top of the left and right sides of the front and rear ends of the U-shaped standard section chute 1; when the through hole at the rear end of the previous standard section chute 1 is aligned with the through hole at the front end of the next standard section chute 1, the latch passes through the through hole to connect the previous standard section chute 1 with the next standard section chute 1. In addition, there are many other ways to connect the previous standard section chute 1 with the next standard section chute 1, not limited to this connection method.

[0021] Traditional chutes are long, cannot be disassembled, and are not easy to circulate and store. The utility model is provided with a plurality of standard section chutes 1 connected in sequence, so that the chute device is easy to install, disassemble and transport; and by providing a convex deceleration bump 2 at the bottom of the standard section chute 1, when the chute device performs concrete encapsulation operation on the municipal pipeline 10, the presence of the deceleration bump 2 can effectively reduce the flow speed of the concrete and improve the concrete encapsulation quality.

[0022] Before the municipal pipeline encapsulation construction, adjust the working slope of the chute and select the required chute length according to the trench excavation depth and the diameter of the installed pipeline. To ensure the flow rate of the chute concrete, control the chute slope range to 45°~60°. According to the calculated chute length, select the corresponding number of standard section chutes. Before installing the chute, check whether the chute is intact and the fixing device is reliable. At the same time, according to the length of the encapsulated pipeline required, select a suitable unloading position. The unloading position is generally set in the middle of each section of the pipeline encapsulation. After the chute is installed, use a clean water source to moisten the chute, but there should be no water accumulation. When pouring concrete, control the concrete discharge speed according to the actual needs of the site, and control the concrete pouring thickness to 200-300mm. After the concrete pouring is completed, disassemble the chute from bottom to top, clean the chute device in time to avoid the chute being blocked by the dry and hard concrete residue, and transport the used chute to the cleaning area for cleaning and trimming. After checking that it is correct, store the standard section chute in the tool box for continued use next time.

[0023] As a preferred embodiment, the standard section chute 1 located at the head is used to receive concrete; a discharge hole 3 is opened at the bottom of the standard section chute 1 located at the tail; a hinge 4 is provided on the side of the discharge hole 3, and the hinge 4 is connected to a sealing plate 5, and the sealing plate 5 opens and closes the discharge hole 3 under the action of the hinge 4; when the sealing plate 5 is opened and the concrete flows to the standard section chute 1 at the tail, the concrete is blocked by the sealing plate 5 and discharged from the discharge hole 3.

[0024] In this embodiment, sealing plate fulcrums 11 are further provided on both sides of the standard section chute 1 at the tail; when the sealing plate 5 needs to be opened, the sealing plate 5 leans on the sealing plate fulcrums 11 for greater stability.

[0025] When using traditional chutes for pipeline concrete encapsulation construction, due to the weak quality awareness of construction workers, for the convenience of construction, the concrete on one side of the pipeline is often completely poured before pouring the concrete on the other side. In this way, since the pipeline is not symmetrically stressed, it is bound to affect the quality of the installed pipeline and greatly affect the qualified rate of the pipeline closed water test in the later stage. For this reason, the device is provided with a discharge hole 3 at the bottom of the standard section chute 1 located at the tail; a hinge 4 is provided on the side of the discharge hole 3, and the hinge 4 is connected with a sealing plate 5. When the concrete pouring on one side of the municipal pipeline 10 reaches the standard layer thickness, the sealing plate 5 is opened, and the sealing plate 5 is used to block the concrete in the standard section chute 1 and guide it to the other side of the municipal pipeline 10, and the concrete on the other side can be poured, thereby achieving the requirements of symmetrical pouring, ensuring the quality of concrete encapsulation construction, and also ensuring the quality of the installed pipeline. When the thickness of the concrete on both sides is basically the same, vibration begins, and both sides of the pipeline need to be vibrated at the same time to ensure that the two sides of the pipeline are symmetrically stressed. After the vibration is completed, the concrete is poured again, and the cycle is repeated until the concrete is fully poured.

[0026] As a preferred embodiment, it also includes a horizontal rotating member 6, a vertical support member 7, and a connecting member 8; the connecting member 8 is open at both ends, one end is connected to the standard section chute 1 located at the head, and the other end is connected to one end of the horizontal rotating member 6, and the connecting member 8 is used to receive concrete and make the concrete flow to the standard section chute 1 located at the head under the action of gravity; the other end of the horizontal rotating member 6 is connected to the vertical support member 7, and the horizontal rotating member 6 rotates around the vertical support member 7; the vertical support member 7 stands on the ground.

[0027] In this embodiment, the horizontal rotating member 6 is rotated as needed to more conveniently receive the concrete in the concrete tank truck. At the same time, rotating the horizontal rotating member 6 can also expand the scope of pouring concrete during concrete encapsulation construction without moving the entire device, thereby improving the concrete pouring efficiency.

[0028] As a preferred embodiment, the vertical support member 7 is retractable.

[0029] In this embodiment, the specific structure of the vertical support member 7 is not limited, and the vertical support member 7 can be an electric telescopic rod or a sleeve structure. The vertical support member 7 can be telescopic so that when pouring concrete, the vertical support member 7 can be telescopic as needed to increase or decrease the height of concrete pouring.

[0030] As a preferred embodiment, it also includes a horizontal rotating member 6, a vertical support member 7, and a connecting member 8; the connecting member 8 is open at both ends, one end is connected to the standard section chute 1 located at the head, and the other end is connected to one end of the horizontal rotating member 6, the connecting member 8 is used to receive concrete and make the concrete flow to the standard section chute 1 located at the head under the action of gravity; the other end of the horizontal rotating member 6 is connected to the vertical support member 7, and the horizontal rotating member 6 rotates around the vertical support member 7; it also includes a mobile cart 9, and the vertical support member 7 is connected to the mobile cart 9.
