Abstract
Description
Technical Field
[0001] The present application relates to the technical field of grouting construction, and in particular to a pressure-maintaining and non-return device for grouting of assembled structural sleeves. Background Art
[0002] During the wall construction process, grouting is generally required to fill the embedded connectors with concrete, so that a stable connection between adjacent walls can be achieved after the concrete solidifies.
[0003] The most widely used grouting pipe in engineering adopts a straight-through connection form. The grouting material is injected into the connecting parts of the wall through professional grouting equipment. The connecting parts are generally in the form of a sleeve. Rebars are inserted in the sleeve. A grouting port is opened at the lower end of the sleeve, and a grouting outlet is opened at the upper end of the sleeve. When the grouting pipe of the grouting equipment is inserted into the grouting port, the grouting equipment injects the grouting material into the sleeve through the grouting port. After the sleeve is filled, it flows out from the grouting outlet. It is necessary to seal the grouting outlet with a wooden plug in time, and immediately continue to seal the grouting port with a wooden plug after pulling out the grouting pipe of the grouting equipment.
[0004] In the above-mentioned method of preventing the grouting liquid from flowing back, there is a backflow in the process of blocking the slurry outlet. Utility Model Content
[0005] In order to reduce the degree of backflow at the slurry outlet, the present application provides a pressure-maintaining and non-return device for grouting of an assembled structural sleeve.
[0006] The present application provides a pressure-maintaining and non-return device for grouting of assembled structural sleeves, which adopts the following technical solution:
[0007] A pressure-maintaining and non-return device for grouting sleeves of assembled structures, comprising a tee, wherein the first tube of the tee is installed on the grouting hole of the sleeve, the second tube of the tee is connected to the grouting equipment, and the axes of the second tube and the first tube are perpendicular to each other; the pressure-maintaining and non-return device also includes a wooden plug, which is slidably installed in the third tube of the tee or the first tube, the third tube and the first tube are coaxial, and the tee is provided with a fixing part for fixing the wooden plug.
[0008] By adopting the above technical solution, the device realizes flexible control during the grouting process through the clever design of the three-way pipe structure. The first through-tube is directly connected to the sleeve to ensure accurate grouting; the second through-tube is connected to the grouting equipment to ensure the continuity of the grouting process; the third through-tube is coaxially arranged with the first through-tube, and is installed through the sliding of the wooden plug. At the end of grouting, when the pressure change in the sleeve remains basically unchanged, the liquid flow can be quickly blocked, which can reduce the degree of reflux at the slurry outlet. The setting of the three-way pipe enhances the flexibility and practicality of the device.
[0009] Optionally, the fixing member is a fixing rod, one end of which is fixedly mounted on the wooden plug, and the other end of which is threadedly mounted on the end of the third through pipe.
[0010] By adopting the above technical solution, the fixing rod is used as the fixing part of the wooden plug, which not only simplifies the installation process, but also improves the stability of the fixing of the wooden plug. One end of the fixing rod is fixedly installed on the wooden plug; the other end is threadedly installed on the end of the third through pipe, ensuring the firmness and detachability of the fixing, which is convenient for subsequent maintenance and replacement.
[0011] Optionally, the first through pipe and the grouting hole are threadedly connected.
[0012] By adopting the above technical solution, the threaded connection makes the connection between the first through pipe and the grouting hole tighter and more reliable, effectively preventing the problem of liquid leakage during the grouting process. At the same time, this connection method is also convenient for installation and disassembly, improving work efficiency.
[0013] Optionally, the second through pipe is threadedly connected with a grouting pipe, and one end of the grouting pipe extends out of the second through pipe.
[0014] By adopting the above technical solution, by threading the grouting pipe on the second through pipe and extending one end of the grouting pipe out of the second through pipe, it is not only convenient to connect the grouting equipment, but also makes the grouting process smoother. The design of the grouting pipe makes the grouting operation more flexible and can adapt to different grouting needs.
[0015] Optionally, a slurry outlet is provided on the wall of the grouting pipe. During grouting, the other end of the grouting pipe is located at the connection point of the tee pipe, and the slurry outlet of the grouting pipe is only connected to the first through pipe.
[0016] By adopting the above technical solution, a slurry outlet is opened on the grouting pipe, and the other end is located at the connection point of the three-way pipe during grouting, while ensuring that the slurry outlet is only connected to the first through pipe. This design effectively avoids liquid turbulence during the grouting process and ensures the accuracy and efficiency of grouting.
[0017] Optionally, an observation tube is also included, one end of which is fixedly mounted on the slurry outlet of the sleeve, and an observation hole is opened on the tube wall of the observation tube.
[0018] By adopting the above technical solution, the observation tube is fixedly installed on the slurry outlet hole of the sleeve, and an observation hole is opened. When the grouting material flows out from the observation hole, it indicates that the grouting is completed.
[0019] Optionally, a wooden plug is also slidably disposed in the observation tube.
[0020] By adopting the above technical solution, a wooden plug is also slidably arranged in the observation tube, which further enhances the flexibility of the device. When it is necessary to pause the observation or perform other operations, the observation hole can be blocked by sliding the wooden plug.
[0021] Optionally, the three-way pipe is made of transparent material.
[0022] By adopting the above technical solution and using transparent materials to make the three-way pipe, the entire grouting process is made more transparent. Operators can clearly observe the flow of liquid in the pipe without disassembling the device, which greatly improves work efficiency and safety.
[0023] In summary, the present application includes at least one of the following beneficial effects:
[0024] 1. The use of three-way pipes and wooden plugs can flexibly control the flow of liquid, achieve precise control of grouting operations, and improve the safety and efficiency of operations;
[0025] 2. It is preferred to use a fixing rod as the fixing part. The wooden plug can be conveniently fixed or released by rotating the fixing rod, and the operation is simple and quick. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0029] The following is combined with Figure 1-2 This application is described in further detail.
[0030] The embodiment of the present application discloses a pressure-maintaining and non-return device for grouting of an assembled structure sleeve.
[0031] Example 1
[0032] Reference Figure 1This embodiment discloses a pressure-maintaining and non-return device for grouting sleeves of assembled structures, comprising a tee pipe 2, wherein a first pipe 21 of the tee pipe 2 passes through a wall 10 and is installed on a grouting hole 11 of a sleeve 1, and a second pipe 22 of the tee pipe 2 is sealed and connected to a grouting device, and the axes of the first pipe 21 and the second pipe 22 are perpendicular to each other. The device also comprises a wooden plug 5, which is slidably installed in a third pipe 23 of the tee pipe 2, the third pipe 23 and the first pipe 21 are coaxial, and the outer peripheral side of the wooden plug 5 is completely attached to the inner wall of the third pipe 23.
[0033] The three-way pipe 2 is provided with a fixing member for fixing the wooden plug 5. The fixing member adopts a fixing rod 3, one end of which is fixedly mounted on the wooden plug 5, and the other end is threadedly mounted on the end of the third through pipe 23. The end of the third through pipe 23 is coaxially provided with a threaded sleeve 4, and the outer wall of the fixing rod 3 is distributed with threads threadedly connected with the threaded sleeve 4, and the fixing rod 3 is threadedly mounted on the third through pipe 23 through the threaded sleeve 4. The fixing rod 3 is connected with a handle for easy rotation. When it is necessary to prevent the flow of liquid, the wooden plug 5 is pushed into the third through pipe 23 by rotating the fixing rod 3. There is a certain pressure in the sleeve 1 after grouting, and the wooden plug 5 rotates with the rotation of the fixing rod 3. The wooden plug 5 that continuously rotates into the third through pipe 23 can better overcome the pressure in the sleeve 1, so that the connection between the first through pipe 21 and the second through pipe 22 of the three-way pipe 2 is blocked.
[0034] In this embodiment, the first through pipe 21 and the grouting hole 11 are connected by a threaded connection. This connection method is simple and easy to use, and has good sealing and stability. The installation can be completed by simply screwing the first through pipe 21 into the grouting hole 11, which is convenient and quick. At the same time, the threaded connection is also convenient for future disassembly.
[0035] The second through pipe 22 in this embodiment is also connected to the grouting pipe 6 by threaded connection. The outer pipe wall of the grouting pipe 6 is completely fitted with the inner pipe wall of the second through pipe 22. One end of the grouting pipe 6 extends out of the second through pipe 22 and can be fixedly connected to the grouting pipe of the grouting equipment by a clamp. A grouting outlet 61 is provided on the pipe wall at the other end of the grouting pipe 6. During grouting, the other end of the grouting pipe 6 is located at the three-pipe connection of the tee pipe 2, so that the grouting outlet 61 of the grouting pipe 6 is only connected to the first through pipe 21. This design can ensure the orderly progress of the grouting operation and avoid liquid leakage and waste.
[0036] When the grouting pipe 6 is grouting, it also plays a certain shielding role on the wooden plug 5, reducing the contact between the wooden plug 5 and the grouting material as much as possible. Only when the grouting pipe 6 completely withdraws from the connection of the tee pipe 2 and the grouting pipe 6 is only located in the second through pipe 22, the wooden plug 5 can enter the first through pipe 21.
[0037] The present embodiment provides an implementation principle of a grouting pressure-maintaining and non-return device for an assembled structure sleeve.
[0038] Before grouting, the tee pipe 2 and the observation tube 7 are threadedly installed on the grouting sleeve, and the grouting pipe 6 on the tee pipe 2 is screwed to the head so that the grouting pipe 6 abuts against the inner wall of the connection point of the tee pipe 2. Then the grouting pipe 6 and the grouting pipeline of the grouting equipment are fixedly connected by a clamp and grouting is started. When the slurry outlet hole 12 of the sleeve 1 is slurried, the slurry outlet hole 12 is first sealed with a wooden plug 5, and then the grouting pipe 6 is rotated to make the grouting pipe 6 leave the connection point of the tee pipe 2. At this time, the pressure in the tee pipe 2 is almost the same as the pressure in the sleeve 1, and the grouting material in the sleeve 1 will not flow back quickly. When the grouting pipe 6 no longer blocks the wooden plug 5, the fixing rod 3 is rotated to push the wooden plug 5 into the first through pipe 21 to block the liquid from continuing to flow, thereby reducing the grouting reflux in the sleeve 1 as a whole.
[0039] Example 2
[0040] Reference Figure 2 On the basis of Example 1, a grouting pressure-maintaining and non-return device for assembled structure sleeve further includes an observation tube 7, one end of which is also fixedly mounted on the grouting hole 12 of the sleeve 1 through a threaded structure, and an observation hole 71 is provided on the wall of the observation tube 7. The grouting situation in the sleeve 1 can be visually observed through the observation hole 71. If the grouting material flows out of the observation hole 71, it means that the grouting in the sleeve 1 is completed.
[0041] In this embodiment, a wooden plug 5 is further slidably disposed in the observation tube 7. When the flow of liquid in the observation tube 7 needs to be blocked, the wooden plug 5 can be simply pushed into the observation tube 7. The observation hole 71 is located on the lower surface of the through-tube 7, and the grouting material is not easy to contact the wooden plug 5 when it flows out. This design enables the observation tube 7 to have an observation function, thereby improving the flexibility and versatility of the device.
[0042] The fixing method of the wooden plug 5 on the observation tube 7 is the same as the fixing method of the wooden plug 5 on the three-way pipe 2, and the fixing rod 3 and the observation tube 7 are also threadedly connected.
[0043] The three-way pipe 2 and the observation tube 7 are both made of transparent materials, such as transparent plastic. This design allows the user to visually observe the flow of liquid in the three-way pipe 2 and the observation tube 7, which is convenient for timely discovery of potential problems and handling. At the same time, the transparent material also has good corrosion resistance and wear resistance, which can meet the use requirements in the field of building grouting technology.
[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
