[0020] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined in this application.
[0021] Reference Figure 1 and Figure 2The present invention is an observation device for the fullness of grouting inside a sleeve 1. The main structure includes a connecting pipe 2 connected to the sleeve 1. Grout is poured into the interior of the sleeve 1. The connecting pipe 2 is connected to the sleeve 1 to form a communicating vessel structure, so that the liquid level of the slurry in the sleeve 1 is consistent with that in the connecting pipe 2, thereby facilitating indirect control of the liquid level when the sleeve 1 is about to be filled with full grouting. For the convenience of observation, the connecting pipe 2 can also be set to a transparent material, so that the observation of the slurry level is more direct. The connecting pipe 2 is L-shaped, and a through overflow hole 3 is provided on the side wall of the sleeve 1. When the slurry is about to be filled with full grouting, the slurry will flow out. The overflow hole 3 enters the connecting pipe 2, and the horizontal part of the connecting pipe 2L is connected to the overflow hole 3. Specifically, the end of the horizontal part is connected and fixed to the overflow hole 3 by plugging. The top of the vertical part of the connecting pipe 2L is movably connected with a pipe cap 4, and the pipe cap 4 can be detachably connected to the top of the connecting pipe 2L by means of threaded connection or the like. The height of the pipe cap 4 is higher than the height of the top of the sleeve 1, so that there is enough space in the connecting pipe 2 to ensure that the slurry level of the injection can be kept synchronized with the liquid level in the sleeve 1. The pipe cap 4 is provided with an observation rod 5, and a scale is preferably set on the observation rod 5 so that the observation rod 5 extends out of the pipe cap. The length of the pipe cap 4 can be accurately and timely observed. The observation rod 5 passes through the pipe cap 4 and can move vertically relative to it. The bottom of the observation rod 5 is fixed with a float 6 by welding or bolts. When the slurry level in the connecting pipe 2 rises, the float 6 and the observation rod 5 are driven to rise under the action of buoyancy, so as to accurately control the slurry level of the grouting. Until the observation rod 5 stops rising, that is, when the scale leaked from the observation rod 5 does not change, it indicates that the sleeve 1 is full of grouting. At this time, the grouting can be stopped in time, and the timing of full grouting can be controlled more accurately. Under the premise of ensuring the quality of grouting construction, the accuracy of grouting time is guaranteed. , avoiding the waste of grouting time and further improving the efficiency of grouting construction. A horizontal telescopic rod 7 is sleeved on the L-shaped vertical part of the connecting pipe 2. Preferably, a collar is provided at one end of the telescopic rod 7, which is sleeved on the outside of the connecting pipe 2. A connecting block 8 is welded or bolted to one end of the telescopic rod 7. The connecting block 8 is connected to the side wall of the sleeve 1. Such a structure uses the telescopic rod 7 to reinforce the connection between the sleeve 1 and the connecting pipe 2, avoiding the connecting pipe 2 and the overflow hole 3 from being separated or having gaps under the action of the grouting pressure, resulting in leakage, and ensuring the timeliness and accuracy of the control of the slurry grouting level in the sleeve 1.
[0022] Preferably, the connecting block 8 is made of magnetic material, and the connecting block 8 is magnetically attracted to the side wall of the sleeve 1. Such a structure does not require modification of the side wall of the sleeve 1. The connecting block 8 can be directly attracted to the side wall of the sleeve 1 by magnetism to achieve reinforcement of the connecting pipe 2. After use, it can also be disassembled and recycled, which further simplifies the operation steps and improves the reuse effect of the device.
[0023] Preferably, refer to Figure 3 , a spring 9 is provided at the bottom of the pipe cap 4. Specifically, a rotating block is rotatably provided at the bottom of the pipe cap 4. The spring 9 is fixed to the rotating block by bolts, so that the pipe cap 4 will not drive the spring 9 to rotate when it is rotated to open. The bottom of the spring 9 is connected to the float 6 by bolts. Such a structure allows the pipe cap 4 to be taken out together with the spring 9 and the float 6 after disassembly, which is convenient for reuse, making the device more reusable.
[0024] Preferably, a sealing plug 10 is provided between the L-shaped horizontal part of the connecting pipe 2 and the overflow hole 3. The sealing plug 10 is generally made of rubber material to ensure the sealing effect of the connection, avoid slurry leakage, and ensure the accuracy of slurry injection level observation.
[0025] Preferably, the telescopic rod 7 includes a fixed rod 11 and a sliding sleeve 12. The fixed rod 11 is slidably connected to the inside of the sliding sleeve 12. The ends of the fixed rod 11 and the ends of the sliding sleeve 12 are respectively fixedly connected to the connecting block 8 and the side wall of the connecting pipe 2 by welding or bolts. The corresponding positions of the fixed rod 11 and the sliding sleeve 12 are provided with penetrating positioning holes 13, and a positioning rod 14 is movably inserted into the positioning hole 13. By sliding the fixed rod 11, the length of the fixed rod 11 and the sliding sleeve 12 is matched with the spacing between the sleeve 1 and the connecting pipe 2. Thereafter, the positioning rod 14 is inserted into the positioning holes 13 at the corresponding positions of the fixed rod 11 and the sleeve 1 to achieve the adjustment and fixation of the length of the telescopic rod 7. The structure is simple, the operation steps are further simplified, and the convenience of reinforcing the connecting pipe 2 is ensured.
[0026] Preferably, the pipe cap 4 is provided with a plurality of air holes 15. The setting of the air holes 15 can discharge the air therein from the air holes 15 when the liquid level in the connecting pipe 2 rises, thereby avoiding air compression from hindering the rising of the slurry liquid level in the connecting pipe 2 and ensuring the accuracy of the slurry liquid level observation in the sleeve 1.
[0027] Working principle: The utility model is provided with an L-shaped connecting pipe 2 at the overflow hole 3 on the side wall of the sleeve 1. The horizontal part of the L-shaped connecting pipe 2 is connected to the overflow hole 3, so that the slurry to be poured passes through the overflow hole 3 into the interior of the connecting pipe 2 when it is about to be filled. The top of the vertical part of the L-shaped connecting pipe 2 is movably connected with a pipe cap 4. An observation rod 5 that can move up and down relative to the pipe cap 4 is provided on the pipe cap 4. A float 6 is provided at the bottom of the observation rod 5. When the slurry continues to be poured, this structure will drive the float 6 and the observation rod 5 to rise. When the observation rod 5 continues to rise, it indicates that the slurry has not been poured full. Continue pouring until the height of the observation rod 5 no longer rises, indicating that the slurry has been poured full. After the filling is full, the filling can be stopped at this time. The structure is simple and the operation is convenient, so that the timing of full filling can be controlled more accurately, the quality of the filling construction is guaranteed, and the efficiency of the filling construction is further improved; a horizontal telescopic rod 7 is arranged on the L-shaped vertical part of the connecting pipe 2, and a connecting block 8 is provided at one end of the telescopic rod 7, which is connected to the side wall of the sleeve 1. Such a structure uses the telescopic rod 7 to fix the position of the connecting pipe 2 after installation, to prevent the connecting pipe 2 from being separated from the overflow hole 3 under the action of the filling pressure, to ensure the synchronization of the slurry in the connecting pipe 2 and the slurry liquid level in the sleeve 1, and to make the control of the slurry filling situation in the sleeve 1 more accurate.
