Description

Technical Field

[0001] This application relates to the technical field of building construction, and particularly to a sonic logging pipe structure and grouting equipment. Background Art

[0002] In modern construction projects, the diaphragm wall, as an important part of the deep foundation pit support structure, its construction quality is directly related to the safety and stability of the entire project. However, during the actual construction process, common construction problems such as non-compactness at the bottom of the diaphragm wall and voids existing at the wall edge often occur after the construction of the bottom of the diaphragm wall. These problems not only weaken the bearing capacity of the diaphragm wall but also may lead to serious consequences such as groundwater seepage and foundation pit instability, posing a major threat to the project progress and safety.

[0003] To address the above problems, traditional methods mostly adopt grouting technology to fill the voids to improve the overall performance of the diaphragm wall. However, the existing grouting technology faces many challenges in practical applications. For example, after the conventional sonic logging pipe completes the ultrasonic detection task, additional grouting and plugging are required, and it cannot be directly converted into a grouting pipe for use, resulting in the need to set up a grouting pipe separately, increasing the construction cost and time.

[0042] During the construction process of a building, diaphragm walls are usually constructed using reinforced concrete structures. During the construction process, common construction problems such as incomplete compaction at the bottom of the concrete wall and gaps at the wall edges may occur. To solve this problem, after ultrasonic testing of the sonic logging tube 100, the sonic logging tube 100 is used as a grouting tube to grout the bottom or the edges of the wall, thereby filling the possible gaps at the wall edges and making the bottom of the wall more compact. Specifically, the solution mainly involves setting a pressure grouting device 300 that can conduct unidirectionally at the bottom and outer surface of the sonic logging tube 100, and conducting unidirectionally from the inside to the outside of the sonic logging tube 100, so that the external slurry cannot enter the sonic logging tube 100 through the pressure grouting device 300. After the external concrete is poured and tested through the sonic logging tube 100, grouting can be carried out into the sonic logging tube 100, and then the slurry enters the bottom or the edges of the wall through the pressure grouting device 300 to achieve the reinforcement of the bottom of the wall and the filling of the gaps at the wall edges.

[0043] In this application, the coupling sleeve 200 connects and communicates two adjacent sonic logging tubes 100. The sonic logging tubes 100 are welded to the corresponding steel reinforcement cages. After the steel reinforcement cages are filled with concrete slurry, the possible gaps at the wall edges can be filled with the slurry from the sonic logging tubes 100 through the pressure grouting device 300.

[0044] The sonic logging tube structure provided in this application includes a sonic logging tube 100, a coupling sleeve 200, and a pressure grouting device 300. Among them, the coupling sleeve 200 is located between two adjacent sonic logging tubes 100, and the coupling sleeve 200 is used to connect two adjacent sonic logging tubes 100. The pressure grouting device 300 is installed on the coupling sleeve 200, and the pressure grouting device 300 can conduct unidirectionally and is in communication with the inner cavity of the coupling sleeve 200.

[0045] Refer to Figure 1 and Figure 2 As shown, in this application, the coupling sleeve 200 is used to connect two adjacent sonic logging tubes 100, and since the inside of the sonic logging tube 100 is hollow, the two adjacent sonic logging tubes 100 can be communicated through the sonic logging tube 100.

[0046] At least one connection hole is provided on the outer surface of the connecting sleeve 200, so that the acoustic pipe 100 can at least form a tee structure. The connection hole on the outer surface of the connecting sleeve 200 is connected to a grouting device 300 communicating with its interior, and the grouting device 300 has a one-way conduction function; when multiple grouting devices 300 are required, only multiple connection holes need to be provided on the connecting sleeve 200.

[0047] In this embodiment, the one-way conduction is only in the outward direction from the acoustic pipe 100 to the grouting device 300, and it is blocked in the direction from the outside to the acoustic pipe 100. The purpose is that before grouting the acoustic pipe 100, it is necessary to pour and treat the space or wall outside the acoustic pipe 100. In order to prevent the external slurry from entering the acoustic pipe 100, the one-way conduction function of the grouting device 300 is used to block the slurry and prevent the slurry from entering the acoustic pipe 100 and causing blockage. If there is slurry in the acoustic pipe 100, the ultrasonic detection process cannot be carried out; after the detection is completed and grouting of the acoustic pipe 100 is required, the slurry enters the wall through the grouting device 300 to fill the possible gaps in the wall.

[0048] Threads are provided on the inner wall or outer wall of the connecting sleeve 200, and the connecting sleeve 200 is connected to the adjacent acoustic pipe 100 by threads.

[0049] Refer to Figure 1 and Figure 2 As shown, in this embodiment, when the inner wall of the connecting sleeve 200 is provided with internal threads, the outer surface of the adjacent acoustic pipe 100 is provided with external threads; when the outer wall of the connecting sleeve 200 is provided with external threads, the inner wall of the adjacent acoustic pipe 100 is provided with internal threads. In practice, it can be selected and used according to the processing difficulty and different needs, and no limitation is made here.

[0050] The helix direction of the thread can also be selected according to needs. For example, positive helix threads or reverse helix threads can be selected. In this embodiment, reverse threads are selected for both the connecting sleeve 200 and the acoustic pipe 100.

[0051] In this embodiment, in order to grout the wall bottom to increase its strength, the end of the lowermost acoustic pipe 100 has a connector 600, and the grouting device 300 is installed at the end of the connector 600 away from the lowermost acoustic pipe 100.

[0052] Continue to refer to Figure 1 and Figure 2 , the grouting device 300 at the bottom of the lowermost acoustic pipe 100 also has a one-way conduction function. The difference is that the grouting device 300 is located at the bottom of the lowermost acoustic pipe 100. Thus, when grouting the acoustic pipe 100, the slurry grouts the wall bottom through the lowermost grouting device 300 to make the wall bottom more dense and firm.

[0053] In this embodiment, the grouting device 300 at the bottommost part extends beyond the steel reinforcement cage by at least 50 mm. The purpose is that the slurry outlet of the grouting device 300 can grout the bottom of the steel reinforcement cage to prevent the slurry outlet of the grouting device 300 from being blocked by the previously poured concrete. Of course, in this application, the distance that the grouting device 300 at the bottommost part extends beyond the steel reinforcement cage can also be other distances, which are not specifically limited here.

[0054] Refer to Figure 1 、 Figure 2 and Figure 5 As shown, it can be understood that the connector 600 is a connecting pipe, which is connected to the grouting device 300 through the connecting pipe. It can be connected by means of threaded connection or other means, which are not limited here.

[0055] A communicating pipe 400 is fixedly connected to the outer surface of the connecting sleeve 200. The communicating pipe 400 communicates with the inner cavity of the connecting sleeve 200. The connecting sleeve 200 is installed at the end of the communicating pipe 400 away from the connecting sleeve 200. The grouting device 300 communicates with the inner cavity of the connecting sleeve 200 through the communicating pipe 400.

[0056] Refer to Figures 1 to 4 As shown, in order to enable the slurry from the sonic logging tube 100 to be conveyed to the wall side, the communicating pipe 400 is required for conveying. The slurry from the sonic logging tube 100 is first conveyed into the communicating pipe 400, and then the slurry enters the wall side through the grouting device 300 to fill the gap at the wall side.

[0057] In this embodiment, the communicating pipe 400 can be a rigid pipe body or a flexible metal pipe body. Specifically, when it is a rigid pipe body, the communicating pipe 400 can be a hollow steel pipe. If it is a flexible pipe body, it can be a gooseneck pipe. It should be noted here that the gooseneck pipe can be bent at a certain angle. The gooseneck pipe is well known to those skilled in the art and will not be elaborated in detail here.

[0058] Fixing members 500 are provided on one side of the connecting sleeve 200. The fixing members 500 include fixing plates 510. The fixing plates 510 are provided with protruding portions 520. A limiting hole 530 adapted to the communicating pipe 400 is formed through the protruding portions 520.

[0059] Refer to Figure 1 and Figure 6 As shown, in order to prevent the slurry from damaging the communicating pipe 400 or causing its position to move during external grouting, fixing members 500 need to be provided at the position of the communicating pipe 400 to fix it and prevent it from being damaged.

[0060] Continue to refer to Figure 1 andFigure 6 During installation, first, pass the limit hole 530 through the connecting pipe 400, and then weld the fixing plate 510 to the steel reinforcement cage. The fixing plate 510 and the protruding part 520 form a stable "convex" shape, thereby fixing the connecting pipe 400 and preventing the connecting pipe 400 from being damaged or displaced by external forces.

[0061] The grouting device 300 includes a fixed pipe 310. A connecting part 320 is provided at the end of the fixed pipe 310 close to the connecting sleeve 200. A grouting port 330 is provided at the end of the fixed pipe 310 far from the connecting sleeve 200. A one-way conduction structure 340 is provided at the end of the fixed pipe 310 far from the connecting part 320. The one-way conduction structure 340 is used for one-way conduction of the grouting port 330. There are a plurality of the grouting ports 330, and the grouting ports 330 are evenly spaced about the axis of the fixed pipe 310.

[0062] Since the processes of bottom wall grouting and side wall grouting are the same, here, side wall grouting is taken as an example.

[0063] Refer to Figure 7 、 Figure 8 、 Figure 10 and Figure 11 As shown in

[0064] The one-way conduction structure 340 includes a first ring body 341 and a second ring body 342 provided at the end of the fixed pipe 310. The first ring body 341 and the second ring body 342 define a conduction chamber 343. The outlet of the grouting port 330 is located in the conduction chamber 343. A sealing plate 344 is provided at the opening of the second ring body 342 far from the connecting part 320. The sealing plate 344 is used to block the opening of the sealing plate 344. A sealing sleeve 345 is provided on the outer circumferential surface of the second ring body 342. The sealing sleeve 345 can be deformed under force. The connection between the sealing sleeve 345 and the second ring body 342 is located between the outlet of the grouting port 330 and the second ring body 342.

[0065] Refer to Figure 8As shown, when pouring concrete for steel bars, in order to prevent the concrete slurry or other foreign objects from entering the sonic logging tube 100 through the channel formed by the grouting port 330, the fixed tube 310, and the connecting tube 400, a deformable sealing sleeve 345 is required to block the outlet of the grouting port 330. The concrete abuts against the sealing sleeve 345, and the force of the concrete acting on the sealing sleeve 345 causes the sealing sleeve 345 to deform. A part of the outer surface of the sealing sleeve 345 abuts against the inner wall of the first ring body 341 and may also abut against the surface of the grouting port 330, thereby realizing the closure of the opening of the conduction chamber 343 and the blocking of the outlet of the grouting port 330, preventing the external concrete slurry from entering the fixed tube 310 through the conduction chamber 343 and the grouting port 330.

[0066] Refer to Figure 9 As shown, Figure 9 FIG. is a schematic diagram of the state where the sealing sleeve 345 no longer blocks the conduction chamber 343 and the grouting port 330. Specifically, when it is necessary to fill the gap along the wall through the grouting port 330, the high-pressure slurry will enter the conduction chamber 343 through the grouting port 330. As the slurry continues to be conveyed, the sealing sleeve 345 will undergo a certain deformation, and the sealing sleeve 345 will no longer block the opening of the grouting port 330 and the opening of the conduction chamber 343. Thus, the slurry from the fixed tube 310 will enter the gap along the wall through the grouting port 330 and the conduction chamber 343 to complete the filling of the gap along the wall.

[0067] In this embodiment, in order to prevent the slurry from the fixed tube 310 from entering the sealing sleeve 345, the opening of the second ring body 342 is blocked by a sealing plate 344, thereby preventing the slurry from entering the sealing sleeve 345. For example, the sealing sleeve 345 is a rubber sleeve and can undergo a certain deformation. Of course, the sealing sleeve 345 can also be made of other materials, and the specific material is not limited here.

[0068] The inner diameter of the first ring body 341 and the inner diameter of the second ring body 342 gradually increase in the direction away from the connecting portion 320.

[0069] Refer to Figure 11 As shown, both the first ring body 341 and the second ring body 342 are conical, and the slope of the first ring body 341 is greater than the slope of the second ring body 342, so as to form a larger conduction chamber 343, which is convenient for filling the gap along the wall from the fixed tube 310 through the grouting port 330 and the conduction chamber 343.

[0070] The present application also discloses a grouting device for grouting the acoustic logging tube structure described above, including a grouting machine 700 and a grouting head connected to the grouting machine 700. The grouting head includes a first pipeline 800 and a second pipeline 1000. A water bag 900 is arranged at the end of the first pipeline 800. The first pipeline 800 is connected to the water bag 900. The outlet of the second pipeline 1000 is located below the water bag 900.

[0071] Referring to Figure 1 and Figure 12 As shown, when grouting, the grouting head is placed at the bottom of the acoustic logging tube 100. Water is injected into the water bag 900 through the first pipeline 800 to make it expand, so as to seal the gap between the second pipeline 1000 and the inner wall of the acoustic logging tube 100. When grouting, the pressure inside the tube is increased, which can enable the slurry to better pass through the grouting device 300 and enter the gap at the bottom or side of the wall. Then, the inside of the acoustic logging tube 100 is grouted through the second pipeline 1000, and the grouting is gradually completed from bottom to top.
