Detailed Implementation

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] See attached document Figures 1-6This utility model provides a grouting sleeve for dam construction that can monitor grout fullness. It includes an upper cylinder 100, with a lower cylinder 200 connected to the bottom of the outer wall of the upper cylinder 100. A grout discharge pipe 110 and a grouting pipe 120 are respectively connected to the upper side of the outer wall of the upper cylinder 100. The grout discharge pipe 110 is used to discharge excess grout during grouting, while the grouting pipe 120 is used to inject grout into the upper cylinder 100. Both the inner walls of the upper cylinder 100 and the lower cylinder 200 are equipped with a first detection sensor 204 and a second detection sensor 320 to monitor grout fullness. The first detection sensor 204 and the second detection sensor 320 can be selected as corresponding pressure sensors or liquid level sensors as needed. When the grouting material enters and fills the sleeve, the grout level inside the sleeve is monitored. The pressure sensor detects pressure changes and analyzes the data to determine if the grouting status is normal. The liquid level sensor monitors the liquid level of the grouting material in real time to ensure that the grouting material fills the entire sleeve. The upper cylinder 100 has a main body 130 of steel bars to be fixed inside. The lower cylinder 200 has a two-section structure. The top of the outer wall of the lower cylinder 200 is integrally fixed with a connecting thread 201. The bottom of the inner wall of the upper cylinder 100 and the corresponding position of the connecting thread 201 are provided with an internal thread groove for connection. The outer wall of the connecting thread 201 is threaded to the inner wall of the internal thread groove. After the personnel connect the lower cylinder 200, they can first install the lower cylinder 200 on the bottom of the inner wall of the upper cylinder 100 through the connecting thread 201. In this way, the personnel can easily install and disassemble the lower cylinder 200.

[0026] The inner wall of the lower cylinder 200 is provided with a first sensor mounting groove 203 for installing the first detection sensor 204. The first detection sensor 204 is fixed to the inner wall of the first sensor mounting groove 203. The first detection sensor 204 can be detachably fixed to the inner wall of the first sensor mounting groove 203, so that personnel can easily remove the first detection sensor 204 from the first sensor mounting groove 203 after disassembling the lower cylinder 200. The first detection sensor 204 can be fixed to the inner wall of the first sensor mounting groove 203 by bolts or clips. Positioning pins are fixed to the contact ends of the outer walls on opposite sides of the two sections of the lower cylinder 200. Positioning pins 202 and positioning slots are provided, and the positioning pins 202 and positioning slots are staggered. The two lower cylinders 200 are connected by aligning the positioning pins 202 and positioning slots. The positioning pins 202 and positioning slots make it easy for personnel to connect and splice the two lower cylinders 200 together. The upper cylinder 100 and the lower cylinder 200 are fixed with fixing rings 210 on opposite outer walls. The two fixing rings 210 are fixedly connected by locking bolts 220. The fixing rings 210 are provided so that after the personnel install the lower cylinder 200 at the bottom of the upper cylinder 100, the fixing rings 210 can be fixed together by locking bolts 220, thereby improving the fixing effect of the upper cylinder 100 and the lower cylinder 200.

[0027] The upper cylinder 100 is provided with a fixing component for fixing the second detection sensor 320. The fixing component includes a second sensor mounting base 310, which is opened on the outer wall side of the upper cylinder 100. The inner wall of the second sensor mounting base 310 is connected to the inner wall side of the upper cylinder 100 through a slot. The second sensor mounting base 310 can be opened at the position where personnel need to install the second detection sensor 320. The second detection sensor 320 is installed on the second sensor mounting base 310. The inner wall of the upper cylinder 100 is provided with a groove for the wire harness to pass through. A sealing ring 330 is fixed to the inner wall of the upper cylinder 100 and to the outer side of the second sensor 320. A sealing plate 300 is fixed to the end of the upper cylinder 100 away from the second sensor 320. The outer wall of the sealing plate 300 is fixed to the upper cylinder 100 with bolts. The second detection sensor 320 can be installed on the inner wall of the second sensor mounting base 310. The sealing ring 330 can seal the gap between the second detection sensor 320 and the second sensor mounting base 310. The sealing plate 300 is used to seal the open end of the second sensor mounting base 310. Rotary shafts are fixed on both sides of the outer wall of the upper cylinder 100 and on both sides of the second sensor mounting base 310. A baffle is rotatably connected to the end of each rotating shaft away from the upper cylinder 100. The end furthest from the rotating shaft abuts against both sides of the outer wall of the sealing plate 300. After the personnel first abut against the sealing plate 300 on the second sensor mounting base 310, the baffle can be rotated to make it press against the outer wall of the sealing plate 300. In this way, the sealing plate 300 can be simply fixed on the second sensor mounting base 310. Then, the personnel can fix the sealing plate 300 to the second sensor mounting base 310 with bolts. A certain damping can be set between the baffle and the rotating shaft to improve the stability of the baffle pressing against the sealing plate 300.

[0028] The usage process of this utility model is as follows: Those skilled in the art can first assemble the device according to the above instructions, then connect all electrical equipment to an external power supply, and control the operation of the device through an external controller. Then, personnel can install the required first detection sensor 204 and second detection sensor 320 in their corresponding positions. Next, personnel can first align the lower cylinder 200 with the upper cylinder 100 via the connecting thread 201, ensuring alignment with the fixing ring 210. Simultaneously, personnel can wrap sealing tape or install sealing strips on the connecting thread 201 to improve the sealing of the connection. Finally, the fixing ring 210 is fixed using the locking bolt 220. The upper cylinder 100 and the lower cylinder 200 can be fixedly connected (personnel can mark the screw-in points on the upper cylinder 100 and the lower cylinder 200 so that the fixing ring 210 can be aligned after rotation). Then, the personnel can insert the bottom end of the sleeve to the construction end position of the dam. Then, the personnel can insert the main body of the steel bar 130 into the interior of the upper cylinder 100. Then, the grout is injected through the grouting pipe 120 so that the grout can fill the interior of the upper cylinder 100. At the same time, the first detection sensor 204 and the second detection sensor 320 installed can be powered on to detect the state and level of the grout in the upper cylinder 100 and transmit the detection data to the personnel's uplink receiving end for viewing via data cable.

[0029] When the first detection sensor 204 or the second detection sensor 320 malfunctions, personnel can choose to remove the lower cylinder 200, open the lower cylinder 200, take out the first detection sensor 204, and then remove the bolts of the fixing sealing plate 300 and the second sensor mounting base 310, so that the second detection sensor 320 can be taken out for repair or replacement.

[0030] Specifically, since the outer wall of the lower cylinder 200 is located at the bottom and often needs to extend into the construction area of ​​the dam, the first detection sensor 204 needs to be installed on the inner wall side of the lower cylinder 200 to avoid damage to it when inserting or removing the sleeve.

[0031] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
