Description

Technical Field

[0001] The invention relates to the technical field of grouting and sealing construction, in particular to a device for realizing integrated operation of grouting and sealing and a working method thereof. Background Art

[0002] Prefabricated components of civil engineering assembly structures are generally connected through hollow connectors. After being assembled in place, liquid grouting materials with a certain solidification strength and solidification time are poured into the cavity of the connector through the grouting port of the connector by applying pressure with mechanical equipment, so that the cavity of the connector is filled and sealed. Finally, a dense and reliable connection is formed between the prefabricated components to achieve coordinated force. The process of pouring grouting materials is generally called grouting in engineering.

[0003] During the grouting construction process, when the grouting is completed, it is necessary to pull the end of the grouting equipment - currently the most common is a variable diameter cylindrical steel joint, from the grouting port of the connector, and quickly use a plugging device - currently the most common is a conical wooden plug to block the grouting port to prevent the injected slurry from leaking out due to its own weight. This process is generally called sealing in engineering.

[0004] At present, the end of the equipment generally used for grouting is a simple steel cylinder, which only functions to be inserted into the grouting port of the connector, allowing the slurry to pass through it and be injected into the connector, but does not have its sealing function. As a result, the two construction processes of grouting and sealing cannot be operated in an integrated and continuous manner during the construction process. When the grouting is completed, there is a certain time gap from the process of pulling out the end of the grouting equipment to the process of manually plugging the plugging device into the grouting port. Even for skilled operators, it is difficult to ensure that the gap time between the two processes is short enough every time. This results in the grouting material that has been poured into the inner cavity of the connector leaking out of the grouting port under the action of its own weight during this time gap during the sealing process. This may cause gaps in the inner cavity of the connector that was originally filled, resulting in loose grouting, reducing the connection performance between prefabricated components, and ultimately affecting the overall stress safety of the structure.

[0005] In summary, the engineering community needs a device that can seamlessly connect grouting and grouting sealing and integrate the grouting and grouting construction processes to solve the problem of grouting material backflow caused by the conversion gap between the two construction processes of grouting and grouting sealing in the original construction process. Summary of the invention

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0045] like Figures 1 to 6As shown, a device for realizing integrated grouting and grout sealing operation comprises an outer sleeve, a grout sealing pipe and a grout sealing plug. The front end of the outer sleeve is an unclosed structure and its outer diameter gradually decreases, the rear end of the outer sleeve is a closed structure, the outer sleeve is provided with a through hole along its axial direction, the grout sealing pipe is installed in the through hole, the top of the outer sleeve and the through hole form a closed structure, and the bottom of the outer sleeve and the through hole form an unclosed structure, that is, Figure 1 The planar section method shown divides the outer sleeve and the through hole into upper and lower parts. The upper part of the outer sleeve and the upper part of the through hole form a closed structure, and a gap is formed between the lower part of the outer sleeve and the lower part of the through hole, which is the flow channel of the grouting material.

[0046] A first groove is provided on the top of the outer sleeve, and a second groove is provided on the top of the sealing tube. The width of the first groove is equal to the diameter of the through hole, and the width of the second groove is equal to the diameter of the sealing tube.

[0049] A grouting pipe interface is provided at the bottom of the rear end of the outer sleeve. The grouting pipe interface is an arc-shaped curved pipe and is connected to the grouting equipment through the grouting pipe. The grouting pipe interface is connected to the front end of the through hole. The grouting pipe and the grouting pipe interface are tightly fixed by wrapping the packaging cloth strip to prevent the grouting material from leaking. The grouting equipment injects the grouting material into the flow channel formed by the lower part of the outer sleeve and the lower part of the through hole through the grouting pipe and the grouting pipe interface, and the grouting material enters the front end of the outer sleeve through the flow channel.

[0050] The front end of the outer sleeve is connected to the grouting port of the connector. The grouting port of the connector includes a circular hole and a tapered hole. The circular hole is connected to the tapered hole, and the inner diameter of the tapered hole gradually increases. The front end of the outer sleeve can be inserted into the tapered hole of the grouting port, and the two cooperate with each other. The grouting material at the front end of the outer sleeve slowly enters the circular hole of the grouting port through the tapered hole of the grouting port.

Then put the push rod into the sealing pipe and push the push rod to move the sealing plug forward to the front end of the sealing pipe.

[0060] b. Before the first grouting, the grouting equipment needs to be turned on to allow the grouting material to slowly fill the gap between the bottom of the outer sleeve and the through hole. After the grouting material overflows from the front end of the outer sleeve, the grouting construction can be carried out;

[0061] c. During the grouting construction process, first insert the front end of the outer sleeve with a reduced outer diameter into the tapered hole of the grouting port of the connector, and then turn on the grouting equipment to inject the grouting material;

[0062] d. After the grouting material is poured, the sealing construction is carried out. At this time, the grouting equipment is suspended, and the relative position between the front end of the outer sleeve and the grouting port of the connector is kept unchanged. The operator pushes the push rod with force to quickly insert the sealing plug into the circular hole of the grouting port of the connector to complete the sealing of the grouting port;

[0063] e. After the sealing construction is completed, pull out the push rod and remove the outer sleeve from the grouting port, and repeat the above steps c and d to carry out grouting and sealing construction of other connecting parts.

[0064] The present invention places a grout plug in the grout sealing tube in the front-to-back direction with the front smaller and the back larger through the first slot of the outer sleeve and the second slot of the grout sealing tube, then puts a push rod into the grout sealing tube, pushes the push rod, and advances the grout plug to the vicinity of the front end of the grout sealing tube. After the grouting is completed, the push rod is quickly pushed to quickly insert the grout plug into the circular hole of the grouting port of the connector to complete the grouting port blocking, which can effectively prevent the grouting material from flowing back and ensure the stable connection of the connector to the prefabricated component. In addition, the present invention has a simple structure and is easy to operate.
