[0002] During the construction of pile foundation, grouting treatment is required at the bottom of the pile, so that the slurry penetrates into the sediment layer under high pressure to form an enlarged head at the bottom of the pile to increase the load on the pile end. During the grouting process, one end of the grouting machine needs to be connected to the material container through a pipeline, and the other end needs to be connected to the grouting device through a discharge pipe. Then the grouting device is extended to the bottom of the pile, and the grouting machine is started for grouting.

[0003] During the grouting process, the grouting volume needs to be controlled. The precision flow meters purchased on the market are expensive and easily damaged during cement grouting, which brings great challenges to construction costs and efficiency. In the construction of engineering pile grouting, the flow meter is often a decoration at the beginning of the construction. During the construction process, workers rely on their feelings to grout, which has a great impact on quality management and control. Therefore, it is urgent to design a grouting volume control device that can reduce production costs and improve work efficiency. Utility Model Content

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] like Figures 1 to 5 As shown, a grouting amount control device comprises a material holding barrel 1, which is transparent and has scale lines on its outer wall, and the material holding barrels 1 on both sides of the scale lines are respectively fixed with connecting seats 6 along their axial direction, and the two connecting seats 6 are provided with a movable seat 9 that can slide up and down, and the movable seat 9 is made of light material, and a discharge pipe 16 that is connected with the material holding barrel 1 is penetrated on the end surface of the material holding barrel 1, and a switch valve 17 is also provided on the discharge pipe 16. When in use, the end of the discharge pipe 16 is connected to the grouting machine through an external through pipe;

[0025] A cover plate 2 is placed in the material containing barrel 1, and a plurality of placement grooves are evenly opened on the bottom surface of the cover plate 2 and buoyancy balls 3 are arranged in the placement grooves. A pull rope 13 is provided at the central position of the top surface of the cover plate 2, and counterweight blocks 4 are symmetrically provided at both ends. Handles 5 are also provided on the top surfaces of the two counterweight blocks 4, respectively. With the action of the handles 5, the cover plate 2 can be conveniently and quickly taken and placed. The other end of the pull rope 13 is fixedly connected to the moving seat 9, and detection devices are also provided on the connecting seat 6 and the moving seat 9.

[0026] The detection device includes a proximity switch 10 and a detection block 12. Installation grooves are equidistantly provided on any connecting seat 6 along its height direction, and a proximity switch 10 is provided in the installation groove. Each proximity switch 10 is independently connected to the controller by respective wires, and the controller is also connected to the grouting machine by common wires. An extension end 11 is provided on the movable seat 9, and a detection block 12 adapted to the proximity switch 10 is provided on the extension end 11.

[0027] Through the above structure, when the slurry in the barrel 1 descends, the cover plate 2 will automatically lower, and under the action of the pull rope 13, the movable seat 9 will be driven to move upward, and then the detection block 12 and the proximity switch 10 will be in a coincidence state, so that the proximity switch 10 receives the signal, and under the action of the controller, the grouting machine is shut down. When grouting again, the proximity switch 10 is first put in a power-off state, and then the grouting machine is started to carry out the grouting operation. During the grouting process, the above operations are repeated to effectively control the grouting amount.

[0028] A thread is formed on the outer wall of each proximity switch 10 and two locking nuts matching the thread are disposed on the thread. The two locking nuts are respectively abutted against the two ends of the connecting seat 6. When the two locking nuts are tightened, the proximity switch 10 is installed.

[0029] Embodiment 2

[0030] Based on the first embodiment, Figure 1 and Figure 2 As shown, the specific structure for making the moving seat 9 slide up and down smoothly is as follows:

[0031] A mounting bracket 14 is provided on the top surface of the material containing barrel 1 corresponding to the pull rope 13, and a guide wheel 15 is rotatably provided on the mounting bracket 14. The pull rope 13 passes around the guide wheel 15 and is fixedly connected to the moving seat 9. The setting of the guide wheel 15 can ensure the stability of the pull rope 13 moving up and down.

[0033] In specific use, firstly, the end of the discharge pipe 16 is connected to the external grouting machine through the through pipe, and the grouting machine is started to perform grouting operation. During the grouting process, the slurry in the material holding barrel 1 will drop, and the cover plate 2 will be automatically lowered at this time. Under the action of the pull rope 13, the movable seat 9 is driven to move upward, and then the detection block 12 and the proximity switch 10 are in a coincidence state, so that the proximity switch 10 receives the signal, and under the action of the controller, the grouting machine is stopped to control its grouting amount. When grouting again, the proximity switch 10 is first turned off, and the grouting machine is started to perform grouting operation. During the grouting process, the above operation is repeated to effectively control the grouting amount, thereby improving the use efficiency of the device.

[0034] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto.
