[0029] Example 1

[0030] The embodiment of the present invention provides a prestressed pipe grouting device, such as Figure 1-Figure 6As shown, it includes: an installation base 1, a mixing barrel 2 is arranged above the installation base 1, a feeding barrel 3 is arranged above the mixing barrel 2, the bottom of the feeding barrel 3 is connected with the inside of the mixing barrel 2 through a feeding pipe 4, a partition 5 is arranged in the feeding barrel 3, the partition 5 divides the feeding barrel 3 into a feeding chamber 6 and a suction chamber 7, a driving component is arranged in the feeding chamber 6, a suction component is arranged in the suction chamber 7, a discharge pipe 8 and an extraction pipe 9 are respectively arranged on the side walls of the feeding barrel 3, one end of the discharge pipe 8 is connected with the inside of the suction chamber 7, and the other end of the discharge pipe 8 is connected with the outside of the feeding barrel 3, a first one-way valve is arranged in the discharge pipe 8, one end of the extraction pipe 9 is connected with the inside of the suction chamber 7, the other end of the extraction pipe 9 extends to the mixing barrel 2 and is provided with an extraction block 10, a second one-way valve is arranged in the extraction pipe 9, a discharge pipe 11 is arranged at the bottom of the mixing barrel 2, the discharge pipe 11 is connected with the input end of a discharge pump 12, and a grouting pipe 13 is arranged at the output end of the discharge pump 12.

[0031] The working principle and beneficial effects of the above technical scheme are as follows: the mixing barrel 2 is installed on the mounting base 1 through a support frame, and the raw materials for preparing the grouting material are put into the feed barrel 3. The prepared raw materials drive the driving component to move and flow into the mixing barrel 2 through the feed pipe 4. After being stirred and mixed evenly in the mixing barrel 2, the grouting material is made. Then, the discharge valve on the discharge pipe 11 is opened, and the discharge pump 12 is started. Then, the grouting operation can be carried out into the pipeline through the grouting pipe 13, so that the grouting material is injected into the pipeline and fills the pipeline evenly and fully. When the prepared raw materials flow through the feed chamber 6, the exhaust component in the exhaust chamber 7 works to enable the air in the mixing barrel 2 to enter the exhaust pipe 9 through the exhaust pipe, and flow into the exhaust chamber 7 through the exhaust pipe 9, and finally be discharged from the exhaust pipe 8 to the outside of the feed barrel 3. The setting of the first one-way valve and the second one-way valve can ensure the one-way flow of air. In the present invention, the air in the mixing barrel 2 can be sucked into the exhaust chamber 7 through the extraction pipe 9 and discharged from the discharge pipe 8, thereby reducing the air in the mixing barrel 2, thereby reducing the generation of bubbles inside the grouting material, improving the grouting quality, ensuring the smooth grouting of the pipeline, and improving the density and durability of the grouting material after construction, thereby improving the construction quality. In addition, the reduction of bubbles in the grouting material can improve the fluidity and filling performance of the grouting material, so that the grouting material can fully fill the prestressed pipe, thereby improving the overall stability of the structure.

[0032] Example 2

[0033] On the basis of the above-mentioned embodiment 1, Figure 1 , Figure 2 As shown, a feed pipe 14 is connected to the feed barrel 3 , and a feed funnel 15 is arranged at the upper end of the feed pipe 14 .

[0034] The working principle and beneficial effects of the above technical solution are as follows: the raw materials for preparing the grouting material are first put into the feed funnel 15, and then enter the feed cavity 6 of the feed barrel 3 through the feed pipe 14. By setting the feed funnel 15, the feeding of the grouting material is facilitated.

[0037] The air extraction component includes a plurality of air extraction blades 18 , which are arranged on the outer wall of the rotating shaft 16 , and are distributed in a circular array about the central axis of the rotating shaft 16 . The air extraction blades 18 are located in the air extraction cavity 7 .

[0038] The working principle and beneficial effects of the above technical scheme are as follows: when the raw materials for preparing the grouting material are put into the feed barrel 3, the raw materials for preparing the grouting material can drive the receiving plate 17 to move, thereby driving the rotating shaft 16 to rotate in the feed barrel 3. The rotation of the rotating shaft 16 can drive the exhaust blade 18 in the exhaust chamber 7 to rotate. When the exhaust blade 18 rotates, the gas in the exhaust chamber 7 can be discharged to the outside of the exhaust chamber 7 through the exhaust pipe 8, and then the exhaust pipe 9 exhausts air from the mixing barrel 2 into the exhaust chamber 7, reducing the air in the mixing barrel 2, thereby reducing the generation of bubbles inside the grouting material, and improving the density and durability of the grouting material after construction.

[0039] Example 4

[0040] On the basis of any one of Examples 1-3, Figure 4 As shown, an air inlet cavity is arranged inside the air pumping block 10, and a plurality of air pumping holes 19 are arranged on the outer wall of the air pumping block 10. The air pumping holes 19 are connected with the inside of the air inlet cavity, and the lower end of the extraction pipe 9 is connected with the inside of the air inlet cavity.

[0041] The working principle and beneficial effects of the above technical solution are as follows: when the vacuum assembly is working, the air in the mixing barrel 2 enters the air inlet cavity through the vacuum hole 19 and then flows into the vacuum cavity 7 through the extraction pipe 9.

[0042] Example 5

[0043] On the basis of any one of Examples 1-4, Figure 2 As shown, a mixing barrel 20 is arranged inside the mixing barrel 2, the upper end of the mixing barrel 20 is rotatably connected to the inner wall of the upper end of the mixing barrel 2, the lower end of the feed pipe 4 is connected to the inside of the mixing barrel 20, and a discharge pipe 21 is arranged at the center position of the lower end of the mixing barrel 20, and the discharge pipe 21 adopts a telescopic pipe.

[0044] The working principle and beneficial effects of the above technical solution are as follows: the raw materials for preparing the grouting material flow into the mixing barrel 20 through the feed pipe 4, can be preliminarily mixed inside the mixing barrel 20 to form a grouting amount, and then flow into the mixing barrel 2 through the discharge pipe 21 for secondary mixing, thereby improving the mixing uniformity of the raw materials for preparing the grouting material.

[0045] Example 6

[0046] On the basis of Example 5, Figure 2 , Figure 4 As shown, an extrusion plate 22 is arranged below the vacuum block 10, and the outer periphery of the extrusion plate 22 is slidably connected to the inner wall of the mixing barrel 2, a slurry discharge cavity 23 is arranged inside the extrusion plate 22, the lower end of the discharge pipe 21 is rotatably connected to the center of the extrusion plate 22, the interior of the discharge pipe 21 is connected to the slurry discharge cavity 23, and a plurality of slurry discharge holes 24 are arranged on the lower surface of the extrusion plate 22, and the slurry discharge holes 24 are connected to the interior of the slurry discharge cavity 23.

[0047] The working principle and beneficial effects of the above technical solution are as follows: initially, the extrusion plate 22 contacts the bottom wall of the mixing barrel 2. When the slurry in the discharge pipe 21 flows into the slurry outlet cavity 23, the slurry can flow out from the slurry outlet hole 24, thereby lifting the extrusion plate 22. As the slurry gradually increases, the extrusion plate 22 gradually slides upward along the inner wall of the mixing barrel 2. Under the partition effect of the extrusion plate 22, the air above the extrusion plate 22 can be reduced from flowing into the bottom of the extrusion plate 22, and the air below the extrusion plate 22 is reduced. At the same time, the extrusion plate 22 Downward squeezing can squeeze out the air mixed in the grouting material and extract it through the extraction pipe 9, further reducing the generation of bubbles inside the grouting material during the stirring and mixing process and improving the quality of the grouting material. During the grouting process, as the grouting material in the mixing barrel 2 decreases, the squeezing plate 22 gradually slides downward, and the edge of the squeezing plate 22 can scrape off the grouting material attached to the inner wall of the mixing barrel 2, thereby reducing the waste of the grouting material and automatically scraping and cleaning the inner wall of the mixing barrel 2, reducing the frequency of manual cleaning and alleviating the labor intensity of the staff.
