Description

Technical Field

[0001] The utility model relates to the technical field of grouting sleeves, in particular to a detection device for the fullness and density of grouting sleeves. Background Technique

[0002] The grouting sleeve is also known as the grouting sleeve joint or the sleeve grouting joint. The grouting sleeve is a combination of a specially processed sleeve, a supporting grouting material, and steel bars. When connecting the steel bars, fast-hardening non-shrinking grouting material is injected. Relying on the bonding and biting action between materials to connect the steel bars and the sleeve, the sleeve grouting joint has the advantages of reliable performance, wide applicability, and simple installation; the sleeve grouting connection technology is applicable to fields such as reinforced concrete structure engineering, steel structure engineering, bridge engineering, offshore oil exploitation platform engineering, and offshore wind power towers. The sleeve grouting connection technology is a new type of steel structure connection method generated due to the needs of engineering practice and technological development. The emergence of this connection method makes up for the deficiencies of traditional steel structure connection methods (mainly including welding and bolt connection), and has been rapidly developed and applied.

[0003] At present, when the grouting sleeve is filled, the grouting inside is prone to gaps, resulting in the situation of incomplete grouting. Even if the incompleteness is detected subsequently, it is relatively difficult to replenish the grouting. At the same time, when the grouting sleeve is filled, the slurry outlet hole needs to be quickly covered, and the slurry outlet hole also needs to be quickly opened and closed during subsequent detection. If the closing is too slow, voids will occur. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a detection device for the fullness and density of grouting sleeves to solve the problems mentioned in the above background technology, that is, when the current grouting sleeve is filled, the grouting inside is prone to gaps, resulting in the situation of incomplete grouting. Even if the incompleteness is detected subsequently, it is relatively difficult to replenish the grouting. At the same time, when the grouting sleeve is filled, the slurry outlet hole needs to be quickly covered, and the slurry outlet hole also needs to be quickly opened and closed during subsequent detection. If the closing is too slow, voids will occur.

[0005] To achieve the above object, the utility model provides the following technical solution: A detection device for the fullness and density of a grouting sleeve, comprising a connecting sleeve and a grouting pipe. A sleeve is fixedly installed on the inner wall of the connecting sleeve. An upper steel bar joint and a lower steel bar joint are arranged on the outer surface of the sleeve. A first sealing block is fixedly installed on the outer surface of the upper steel bar joint, and the outer surface of the first sealing block is fixedly connected to the outer surfaces of the connecting sleeve and the sleeve. A second sealing block is fixedly installed on the outer surface of the lower steel bar joint, and the outer surface of the second sealing block is fixedly connected to the outer surface of the sleeve. The output end of the grouting pipe is fixedly communicated with the sleeve through the connecting sleeve. An outlet pipe is fixedly communicated with the outer surface of the connecting sleeve. A through hole is opened on the outer surface of the sleeve away from the outlet pipe. A first telescopic spring is fixedly installed on the outer surface of the first sealing block, and the output end of the first telescopic spring is fixedly installed with a first fixing plate. The outer surface of the first fixing plate is movably attached to the inner wall of the connecting sleeve and the outer surface of the sleeve. A second telescopic spring is fixedly installed on the outer surface of the sleeve, and the output end of the second telescopic spring is fixedly installed with a second fixing plate. The outer surface of the second fixing plate is movably attached to the inner wall of the connecting sleeve and the outer surface of the sleeve.

[0006] Preferably, an L-shaped pipe is threadedly connected to the outer surface of the outlet pipe, and a pressing stop valve is arranged on the outer surface of the L-shaped pipe.

[0007] Preferably, the outlet pipe is arranged above the grouting pipe, and both the first fixing plate and the second fixing plate are semicircular arcs.

[0008] Preferably, the first telescopic spring and the second telescopic spring are arranged oppositely, and the outer surface of the second fixing plate is movably connected to the output end of the outlet pipe.

[0009] Preferably, a plug seat is opened on the inner wall of the L-shaped pipe, and the output end of the pressing stop valve is movably connected to the outer surface of the plug seat.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. For this detection device for the fullness and density of the grouting sleeve, the grouting liquid is grouted through the grouting pipe. First, it flows into the closed space established by the first sealing block, the second sealing block and the sleeve. After being filled, it contacts the first telescopic spring and the first fixing plate through the through hole. The second fixing plate moves along the inner wall of the connecting sleeve and the outer surface of the sleeve. The first telescopic spring and the second telescopic spring continuously extend during the continuous grouting process, vibrating the grouting liquid, so that the grouting liquid is more fully connected with the grouting sleeve, thereby achieving the effect of reducing the occurrence of gaps in the internal grouting of the grouting sleeve during filling, reducing the detection of non-fullness of the sleeve fullness, and making it more difficult to replenish the grouting.

[0012] 2. The grouting sleeve fullness and density detection device has an L-shaped pipe threadedly connected to the outer surface of the slurry outlet pipe. At the same time, a pressing plug valve is arranged on the outer surface of the L-shaped pipe. The L-shaped pipe and the pressing plug valve are vertically arranged, that is, pressing down quickly blocks the slurry outlet pipe, and pulling up allows the slurry outlet pipe to flow through, thus avoiding the problem that voids will occur if the closing is too slow.

[0020] Embodiment 1:

[0021] Please refer to Figures 1-5 ,

[0022] A grouting sleeve fullness and density detection device, including a connecting sleeve 1 and a grouting pipe 2. A sleeve 9 is fixedly installed on the inner wall of the connecting sleeve 1. An upper steel bar joint 6 and a lower steel bar joint 7 are arranged on the outer surface of the sleeve 9. A first sealing block 8 is fixedly installed on the outer surface of the upper steel bar joint 6. The outer surface of the first sealing block 8 is fixedly connected to the outer surfaces of the connecting sleeve 1 and the sleeve 9. A second sealing block 13 is fixedly installed on the outer surface of the lower steel bar joint 7. The outer surface of the second sealing block 13 is fixedly connected to the outer surface of the sleeve 9. The output end of the grouting pipe 2 is fixedly communicated with the sleeve 9 through the connecting sleeve 1. A slurry outlet pipe 3 is fixedly communicated with the outer surface of the connecting sleeve 1. A through hole 10 is opened on the outer surface of the sleeve 9 away from the slurry outlet pipe 3. A first telescopic spring 11 is fixedly installed on the outer surface of the first sealing block 8. The output end of the first telescopic spring 11 is fixedly installed with a first fixing plate 12. The outer surface of the first fixing plate 12 is movably attached to the inner wall of the connecting sleeve 1 and the outer surface of the sleeve 9. A second telescopic spring 14 is fixedly installed on the outer surface of the sleeve 9. The output end of the second telescopic spring 14 is fixedly installed with a second fixing plate 15. The outer surface of the second fixing plate 15 is movably attached to the inner wall of the connecting sleeve 1 and the outer surface of the sleeve 9.

[0023] Specifically, grouting is carried out through the grouting pipe 2. First, it flows into the closed space established by the first sealing block 8, the second sealing block 13 and the sleeve 9. After being filled, it contacts the first telescopic spring 11 and the first fixing plate 12 through the through hole 10. Under the pressure of the grouting liquid, the first telescopic spring 11 extends, driving the first fixing plate 12 to move along the inner wall of the connecting sleeve 1 and the outer surface of the sleeve 9. Then the grouting liquid contacts the second telescopic spring 14 and the second fixing plate 15 through the outer surface of the grouting pipe 2. Under the pressure of the grouting liquid, the second telescopic spring 14 extends, driving the second fixing plate 15 to move along the inner wall of the connecting sleeve 1 and the outer surface of the sleeve 9, making the grouting more delicate, and finally discharging from the slurry outlet pipe 3, thereby achieving the effect of reducing the occurrence of gaps in the internal grouting of the grouting sleeve during filling, reducing the detection of non-fullness of the sleeve fullness, and making it more difficult to replenish grouting.

[0024] In the embodiment: The slurry outlet pipe 3 is arranged above the grouting pipe 2, and both the first fixing plate 12 and the second fixing plate 15 are semicircular arcs.

[0025] Specifically, because the slurry outlet pipe 3 is arranged above the grouting pipe 2, the upward grouting fullness is stronger, and both the first fixing plate 12 and the second fixing plate 15 are semicircular arcs and completely fit the middle gap between the sleeve 9 and the connecting sleeve 1, making the grouting flow along the established route and the fullness stronger.

[0026] In the embodiment: The first telescopic spring 11 and the second telescopic spring 14 are arranged oppositely, and the outer surface of the second fixing plate 15 is movably connected to the output end of the slurry outlet pipe 3.

[0027] Specifically, since the first telescopic spring 11 and the second telescopic spring 14 are arranged oppositely, and the outer surface of the second fixing plate 15 is movably connected to the output end of the slurry outlet pipe 3, the second fixing plate 15 is movably connected to the connection part of the slurry outlet pipe 3 and the connecting sleeve 1 under the push of the grouting, and finally the detection of the grouting fullness degree in the connecting sleeve 1 is completed.

[0028] Working principle: The grouting liquid is grouted through the grouting pipe 2, first flows into the closed space established by the first sealing block 8, the second sealing block 13 and the casing 9, and after being filled, it contacts the first telescopic spring 11 and the first fixing plate 12 through the through port 10. Under the pressure of the grouting liquid, the first telescopic spring 11 extends, driving the first fixing plate 12 to move along the inner wall of the connecting sleeve 1 and the outer surface of the casing 9. The first telescopic spring 11 continuously extends during the continuous grouting process, vibrating the grouting liquid, so that the grouting liquid is more fully connected with the grouting sleeve. The grouting liquid then contacts the second telescopic spring 14 and the second fixing plate 15 through the outer surface of the grouting pipe 2. Under the pressure of the grouting liquid, the second telescopic spring 14 extends, driving the second fixing plate 15 to move along the inner wall of the connecting sleeve 1 and the outer surface of the casing 9, making the grouting more delicate, and finally discharging from the slurry outlet pipe 3. Compared with the related technology, a grouting sleeve fullness and density detection device provided by the present utility model has the following beneficial effects: thus achieving the effect of reducing the occurrence of gaps in the internal grouting of the grouting sleeve during filling, reducing the detection of non-fullness of the sleeve fullness, and making it more difficult to supplement the grouting.

[0029] Embodiment 2:

[0032] Specifically, by threadedly connecting the L-shaped pipe 4 to the outer surface of the slurry outlet pipe 3, and at the same time, a pressing plug valve 5 is arranged on the outer surface of the L-shaped pipe 4. The L-shaped pipe 4 and the pressing plug valve 5 are arranged vertically, that is, pressing down quickly blocks the slurry outlet pipe 3, and pulling up releases the slurry outlet pipe 3, thus achieving the effect of avoiding the problem of voids caused by slow closing.

[0033] In the embodiment: A plug seat is provided on the inner wall of the L-shaped pipe 4, and the output end of the pressing plug valve 5 is movably connected to the outer surface of the plug seat.

[0034] Specifically, since the inner wall of the L-shaped pipe 4 is provided with a plug seat, the output end of the pressing plug valve 5 is movably connected to the outer surface of the plug seat. The pressing plug valve 5 is connected to the plug seat to cut off the flow of the slurry outlet pipe 3, achieving the effect of quick opening and closing.

[0035] Working principle: An L-shaped pipe 4 is threadedly connected to the outer surface of the slurry outlet pipe 3. At the same time, a pressing plug valve 5 is arranged on the outer surface of the L-shaped pipe 4. The L-shaped pipe 4 and the pressing plug valve 5 are vertically arranged, that is, pressing down quickly blocks the slurry outlet pipe 3, and pulling up allows the slurry outlet pipe 3 to flow.
