The top of the horizontally arranged perfusion body is communicated with the vertically arranged connecting cylinder. A snap-type connecting body with a freely adjustable length is connected to the outside of the connecting cylinder, and an output hole body is communicated with the outside of the connecting cylinder. An external connection hole body and an input hole body are opened inside the perfusion body, and a first one-way through self-closing valve body is installed at the position of the external connection hole body inside the perfusion body; in the present invention, the input hole body and the output hole body are aligned with the grouting port and the slurry outlet of the sleeve. The external connection hole body is externally connected to the grouting device. The slurry enters the sleeve through the external connection hole body and the input hole body and is discharged through the slurry outlet. The sponge body is used for air discharge, discharging the air inside the sleeve, and will not discharge the mortar inside the sleeve. After the mortar is filled, the self-weight of the mortar can provide a certain pressure to the mortar inside the sleeve, which can control the grouting in the sleeve to be dense and full, making the slurry compact.

Description

Technical Field

[0001] The present invention relates to the technical field of sleeve grouting, and particularly to a sleeve grouting connector and a grouting method thereof. Background Technique

[0002] The currently used grouting construction method is to pour the slurry into the grouting port of one sleeve opening. The slurry flows in the sleeve cavity and the communication cavity. When the slurry flows out from the grouting ports and the slurry outlet ports of each sleeve, immediately block it with a plug until all the grouting ports and the slurry outlet ports are blocked, and this construction comes to an end.

[0003] However, this setting has the following problems: After the grouting is completed, directly block the discharge hole above the sleeve. At this time, there is air remaining inside the sleeve. Since the air cannot be discharged in time, it causes the slurry to be not compact, and the grouting quality cannot be guaranteed. Therefore, in view of the above problems, a sleeve grouting connector and a grouting method thereof are proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a sleeve grouting connector and a grouting method thereof to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A sleeve grouting connector and a grouting method thereof, including a connecting grouting device, a perfusion body, and a connecting cylinder. The top of the horizontally arranged perfusion body is communicated with the vertically arranged connecting cylinder. A snap-type connecting body with a freely adjustable length is connected to the outside of the connecting cylinder, and an output hole body is communicated with the outside of the connecting cylinder. An external connection hole body and an input hole body are opened inside the perfusion body, and a first one-way passing self-closing valve body is installed at the position of the external connection hole body inside the perfusion body;

[0007] A second one-way passing self-closing valve body is installed inside the connecting cylinder, and the second one-way passing self-closing valve body is located below the snap-type connecting body.

[0008] Preferably, both the first one-way passing self-closing valve body and the second one-way passing self-closing valve body are arranged in a "Y" shape. The first one-way passing self-closing valve body is arranged horizontally, and the second one-way passing self-closing valve body is arranged vertically.

[0009] Preferably, both the first one-way passing self-closing valve body and the second one-way passing self-closing valve body are made of silicone material.

[0010] Preferably, both the perfusion body and the connecting cylinder are made of transparent plastic material.

[0011] Preferably, a sponge body with holes at the top, breathable and impermeable to mortar is fixedly installed at the top of the connecting cylinder.

[0012] Preferably, the snap - type connector can adjust the height of the snap - type connector according to the different distances between the lower grouting hole and the upper air outlet hole in the sleeve, and the adjustable range of its height is 0 - 50 mm.

[0013] Preferably, the sponge body is a medium - density sponge, and the density range is 18 - 45 kg / m3.

[0014] Preferably, it includes the following steps:

[0015] S1: Pre - install the communication controller: Adjust the height of the snap - type connector to an appropriate range so that the input hole body and the output hole body are respectively aligned with the lower grouting hole and the upper air outlet hole in the sleeve, and then fix and install them. At this time, the connection between the sleeve and the communication controller is completed;

[0016] S2: Connect the grouting equipment: Pour the mixed mortar into the grouting equipment, align the end of the grouting pipeline with the external connection hole body of the perfusion body and connect them, and then start the grouting equipment;

[0017] S3: Grouting: Manually pour the mortar until the inside of the sleeve and the communication controller are completely filled with mortar. At this time, the pressure of the mortar in the sleeve is equal to the pressure in the grouting pipeline, and stop grouting.

[0018] S4: Curing and disassembly: After curing the grouted mortar under normal conditions for 28 days, manually disassemble the sleeve grouting connection controller.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This device is installed outside the sleeve. According to the actual height of the sleeve, by adjusting the snap - type connector, its input hole body and output hole body are aligned with the grouting port and the slurry outlet of the sleeve. The grouting equipment is connected through the external connection hole body. At this time, the slurry enters the sleeve through the external connection hole body and the input hole body, and is discharged through the slurry outlet. The set first one - way through self - closing valve body and the second one - way through self - closing valve body ensure the one - way flow of the slurry. The set sponge body is used for air discharge, which can discharge the air inside the sleeve and will not discharge the mortar inside the sleeve. After it is filled with mortar, the self - weight of the mortar can provide a certain pressure to the mortar in the sleeve, which can control the grouting in the sleeve to be dense and full, making the slurry compact.
