[0023] Example
[0024] See also Figure 1-4 As shown:
[0025] The utility model provides a reusable hole sealer, comprising: an isolation part and a filling part. The isolation part is placed at the opening of the blasthole to be sealed, and is provided with a through hole for sealing the filling material of the blasthole to be sealed; the filling part is sleeved on the isolation part and connected to the isolation part, and is used to fill the gap between the isolation part and the inner wall of the blasthole to be sealed.
[0026] Through such an arrangement, during actual construction, the operator injects the sealing material for the blasthole to be sealed through the grouting pipe along the through hole on the isolation part, and the filling part fills the gap between the isolation part and the inner wall of the blasthole to be sealed, so that there is friction between the entire sealer and the blasthole to be sealed, and the sealing material is not easy to be squeezed out of the blasthole to be sealed during the sealing construction, making the entire sealing construction faster and more convenient, thereby improving the construction efficiency.
[0027] The isolation part is mainly composed of an inner end cap 11, an outer end cap 12 and an isolation tube 20. Through holes are provided in the middle of the inner end cap 11 and the outer end cap 12, one end of the isolation tube 20 is connected to the through hole of the inner end cap 11, and the other end is connected to the through hole of the outer end cap 12.
[0028] The inner end cap 11 and the outer end cap 12 are both convex truncated cone shaped, and the outer wall of the convex truncated cone is provided with wave patterns. The wave patterns are used to increase the friction between the two ends of the filling part and the connection between the inner end cap 11, so that the inner end cap 11 and the outer end cap 12 can seal the two ends of the filling part more tightly.
[0029] In actual use, the inner head cover 11 is placed in the blasthole to be blocked, and blocks the blocking material injected into the blasthole to prevent it from overflowing along the blasthole to be blocked during the injection process, and makes the blocking area filled more densely.
[0030] The filling part is mainly composed of an expansion tube 50 , a fixing ring 60 and an inflation tube 31 .
[0031] In actual use, the expansion tube 50 is mounted on the isolation tube 20, and both ends of the expansion tube 50 are provided with annular grooves 51, and the fixing ring 60 is clamped in the annular grooves 51, so that the two ends of the expansion tube 50 are respectively connected to the inner end cap 11 and the outer end cap 12.
[0032] The outer end cap 12 is provided with a joint pipe 121 and an inner air outlet pipe 122; the joint pipe 121 and the inner air outlet pipe 122 are connected, and the joint pipe 121 is connected to the inflation pipe 31, and the inner air outlet pipe 122 is connected to the gap between the expansion pipe 50 and the isolation pipe 20.
[0033] Through such an arrangement, the inflation pipe 31 is connected to the end cap 12 of the outer header, and communicates with the gap between the expansion pipe 50 and the isolation pipe 20. A stop valve is provided on the inflation pipe 31, which is used to prevent the airflow in the gap between the expansion pipe 50 and the isolation pipe 20 from flowing out along the inflation pipe 31.
[0034] During actual construction, the entire hole sealer is placed at the mouth of the blasthole to be sealed, and an air pump is used to inflate the gap between the expansion tube 50 and the isolation tube 20 along the inflation tube 31, so that the extrusion pressure between the outer wall of the entire expansion tube 50 and the inner wall of the blasthole to be sealed is greater, thereby increasing the friction between the entire hole sealer and the inner wall of the blasthole to be sealed and being able to withstand greater extrusion pressure.
[0035] When constructing the plugging end of the blasthole to be plugged, slurry can be injected with high pressure, making the entire plugging construction faster and improving construction efficiency.
[0036] It also includes a fixing pin 41, which is connected to the end cap 12 of the outer plugging device. By setting the fixing pin 41, when the plugging device is exhausted and the connection between the plugging device and the blasthole to be plugged is still tight, the fixing pin 41 can be dragged by a rope to be taken out, which is simple and convenient.
[0037] The hole sealer provided by the utility model can be applied to construction or waterway maintenance, etc. In actual use, the operator only needs to place the hole sealer in the hole that needs to be temporarily sealed, form a tight connection between the filling part of the hole sealer and the hole, and perform the next operation through the openable and closable through hole reserved in the isolation part, thereby increasing the application scenarios of the hole sealer and making the application range of the hole sealer wider.
[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
