Description

Technical Field

[0001] The utility model relates to the technical field of pipeline laying, in particular to a pre-buried pipe filling device. Background Technique

[0002] When laying urban pipelines, it is necessary to excavate the road surface, then lay the pipelines in the excavated pits, and restore the road surface after the pipelines are laid. However, when the laid pipelines cross facilities such as roads, bridges, and buildings, especially when they need to cross busy traffic main roads, the above-mentioned traditional method of excavating the road surface to lay pipelines will directly affect the normal operation of urban traffic, and at the same time, the construction site will also cause environmental pollution. Now, horizontal directional excavation equipment is used for trenchless construction. That is, when crossing a traffic road, construction sites are set on both sides of the road, and then trenchless equipment is used to drill and ream holes on both sides, and then lay pipelines. In this way, pipeline crossing construction can be carried out without affecting traffic. However, when the directional drill drills a hole, in order to facilitate the smooth burial of the pipeline into the hole, the diameter of the drilled hole is larger than the diameter of the pipeline. After the pipeline enters the hole, under the action of gravity, there is a large gap between the lower part of the hole and the upper part of the pipeline. This gap will cause the road surface to settle. Especially when the road surface needs to bear a large load, the road will have serious depressions, endangering the safety of the road. Therefore, a pre-buried pipe filling device is provided to solve the problems raised in the above background technique. Content of the Utility Model

Specific implementation manner

[0021] Please refer to Figures 1 to 4 As shown, the present utility model provides an embedded pipe filling device, including a cement output device and a conveying device. The cement output device includes a mixing tank 1, a mixing motor 2, a mixing rod 3, an auger shaft 4 and a feeding hose 5. A feeding pipe 11 is provided through the lower part of the mixing tank 1. The feeding hose 5 is connected to the feeding pipe 11. The mixing motor 2 is fixed above the mixing tank 1. The mixing rod 3 is arranged in the mixing tank 1 and fixed to the output end of the mixing motor 2. The auger shaft 4 is fixed below the mixing rod 3 and the auger shaft 4 is located in the feeding pipe 11. The conveying device includes a mounting base 6, a driving frame 61, at least two groups of transmission roller sets, and a conveying pipe 9. The mounting base 6 is arranged on one side of the mixing tank 1. The driving frame 61 is fixed on the mounting base 6. The transmission roller set includes a driving roller 7 and a driven roller 8. The driving roller 7 and the driven roller 8 are rotatably arranged at intervals in the vertical direction on the driving frame 61. The conveying pipe 9 is movably arranged between the driving roller 7 and the driven roller 8. A spraying head 10 is arranged on the front side of the conveying pipe 9. The spraying head 10 is connected to the feeding hose 5.

[0022] When the driving wheel rotates, it drives the conveying pipe 9 to move forward into the pores until the conveying pipe 9 moves to the other side opening of the drill hole. Then, the cement to be filled is poured into the cement mixing tank 1. The mixing motor 2 is started. While driving the mixing rod 3 to rotate, it drives the auger shaft 4 to stir. When the auger shaft 4 rotates, it will convey the cement in the mixing tank 1 to the feeding hose 5. Finally, the cement is sprayed out from the spraying head 10 to complete the filling of the pores. When the spraying head 10 sprays, the driving roller 7 rotates reversely, so that the conveying pipe 9 gradually moves backward while spraying until the conveying pipe 9 moves out of the drill hole, and the cement completes the filling of the pores between the pipe and the drill hole, so that the road will not produce a depression condition and the road becomes safer. When the pores are relatively long, the conveying pipe 9 can be driven into the pores at both ends of the opening respectively at the same time, and the cement is filled from both sides.

[0023] Specifically, the two sets of the driving roller groups are arranged at intervals in the front-back direction. Belt pulleys 12 are fixed to one ends of the two driving rollers 7 respectively. A conveyor belt 13 is sleeved outside the two belt pulleys 12. A driving motor 14 is connected to one of the belt pulleys 12.

[0024] The driving motor 14 drives the belt pulley 12 to rotate, thereby driving the two sets of driving wheels to rotate synchronously. The two sets of driving wheels are arranged at intervals, which can not only provide support for the conveying pipe 9, but also provide driving force for the conveying pipe 9, so as to facilitate the conveying pipe 9 to enter the pores.

[0025] Furthermore, a fixing seat 62 is also installed on the mounting seat 6. A guiding roller 15 is rotatably connected to the fixing seat 62. The upper surface of the guiding roller 15 is in contact with the conveying pipe 9.

[0026] By providing the guiding roller 15 to provide auxiliary support for the conveying pipe 9. At the same time, by using the rotation of the guiding roller 15, it provides guidance for the conveying pipe 9, facilitates the forward movement of the conveying pipe 9, and enables it to smoothly enter the pores, and can also prevent one end of the conveying pipe 9 from tilting.

[0027] Even further, a rubber layer is wrapped outside the guiding roller 15. The rubber layer helps to increase the friction between the guiding roller 15 and the conveying pipe 9, so as to facilitate driving the conveying pipe 9 to move forward.

[0028] Specifically, the conveying pipe 9 includes a plurality of pipe sections 93. Installation parts and matching parts are respectively provided at two ends of each pipe section 93. The installation parts and the matching parts on two adjacent pipe sections 93 are connected in a matching manner.

[0029] For the conveying pipe 9 formed by the matching connection of a plurality of pipe sections 93, its length can be controlled, which is convenient for reducing the conveying site and occupied space. The pipe sections 93 can be installed while conveying to lengthen the conveying pipe 9. The conveying pipe 9 composed of a plurality of installed pipe sections 93 is also convenient for transportation.

[0030] The installation part and the matching part can be connected by the cooperation of a clamping protrusion and a clamping groove, or can be connected by a threaded structure.

[0031] Furthermore, a mounting plate 91 is fixedly connected to the front side of the conveying pipe 9. A connecting plate 92 is fixedly connected to the lower side of the mounting plate 91. The connecting plate 92 is in a screw connection with the spraying head 10.

[0032] By providing the connecting plate 92, it is convenient to install the spraying head 10, and it is also convenient to replace the spraying head 10 when the spraying head 10 is damaged.

[0033] Specifically, two groups of spray material branch pipes 101 are fixedly and penetratingly connected to one end of the spray material head 10. By arranging the two groups of spray material branch pipes 101, cement can be evenly laid on both sides of the embedded pipe, so that no voids will appear inside the pores, improving the filling efficiency.

[0034] Specifically, a plurality of stirring blades 31 are installed on the stirring rod 3. The stirring blades 31 can stir the cement inside the stirring tank 1 to prevent the cement from coagulating.

[0035] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
