Description

Technical Field

[0001] The utility model relates to the technical field of grouting machines, in particular to a grouting device for municipal road construction. Background Art

[0002] During the construction of municipal roads, certain curable slurries are injected into the cracks or pores of the rock foundation through appropriate methods. The grouting technology, which improves its physical and mechanical properties through replacement, filling, extrusion, etc., is increasingly widely used. The grouting equipment that has developed accordingly is also becoming more mature and is one of the more common construction equipment in road construction projects.

[0003] The prior art discloses a grouting device for municipal road construction with application number CN202022026632.9, comprising a base, a mixing box is fixedly installed on the top of the base, and the other end of the hard pipe is connected to a grouting pipe, one side of the support plate is fixedly connected to a fixing rod, the outer side of the fixing rod is fixedly sleeved with a winding roller for winding the grouting pipe, the bottom of one side of the support plate is fixedly connected to a connecting block, and one side of the connecting block is fixedly connected to an elastic clip for clamping the grouting pipe. Through the setting of the winding roller and the elastic clip, the grouting pipe can be wound around the winding roller, and then the end of the grouting pipe is clamped by the elastic clip, and then the end of the grouting pipe is fixed, so that the grouting pipe is neatly arranged to avoid the entanglement of the grouting pipe. Through the setting of the scraper, the concrete slurry on the inner wall of the mixing box can be scraped off by the scraper to prevent the concrete slurry from adhering to the inner wall of the mixing box.

[0004] However, the scraper of the device always needs to be in contact with the inner wall of the mixing box. When mixing, the scraper always rubs against the inner wall of the mixing box, which will not only reduce the mixing speed, but also cause wear of the scraper, thereby creating a gap between the scraper and the box wall, which will reduce the scraping effect in the later stage. Secondly, although the device can clean the slurry on the box wall, it cannot clean the inner wall of the pipe. Since accelerators are added to the cement slurry, the residual slurry may cause the grouting pipe to be blocked after use, making the grouting equipment unusable next time. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a grouting device for municipal road construction to solve the technical problems in the above-mentioned background technology.

[0009] Furthermore, a plurality of groups of nozzles are provided at the bottom of the annular tube, and the plurality of groups of nozzles are inclined toward the inner wall of the storage tank.

[0010] By adopting the above technical solution, the residual material on the inner wall of the storage tank can be effectively washed through multiple groups of inclined nozzles, thereby improving the cleaning effect.

The rotation of the one-way screw causes the threaded block to push the scraper to move through the connecting rod, so that the scraper contacts the tank wall, and the water pump draws cleaning liquid from the liquid storage tank, thereby cleaning the residual slurry inside the storage tank. At the same time, the motor drives the reciprocating screw to rotate, thereby causing the rotating tube to rotate, and the rotating tube drives the scraper through the connecting tube to scrape off the residual slurry on the inner wall of the storage tank. At the same time, the rotation of the reciprocating screw causes the threaded plate to move through the piston The rod drives the piston plate to perform piston movement, and then the cleaning liquid inside the storage tank is extracted. The extracted cleaning liquid can flush and clean the residual slurry inside the extraction pipe and the injection pipe. These settings can prevent the scraper from affecting the stirring speed due to friction during stirring work, and avoid the scraper wear affecting the scraping effect. The staff can quickly clean the residual slurry in the grouting machine body more promptly after the grouting is completed, to prevent the cleaning difficulty from increasing after too long, and to prevent the grouting machine body from being damaged due to delayed cleaning. In addition, there is no need to set up a extraction pump, which greatly reduces the construction cost and energy consumption, and is ideal for environmental protection.
