Problems solved by technology

Although the sleeve grouting connection is more commonly used, due to the complex operation of the sleeve grouting construction, the uneven quality of the construction personnel, and the difficulty of visual inspection of the construction quality, the grouting is often not full, which also brings difficulties to the on-site inspection personnel. Detection trouble
However, if the pipe is blocked during the grouting process, it is easy to have a large grouting pressure or overflow of the grout, which will cause the illusion that the sleeve is full and affect the actual grouting quality of the sleeve.

Embodiment 1

[0037] refer to Figure 1 to Figure 3 , the technical scheme of a prefabricated structure intelligent sleeve grouting device of this embodiment is as follows:

[0038] An assembled structure intelligent sleeve grouting device, comprising a hopper 1, a material box 2, a screw pump 3, a grouting pipe 4, a pressure sensor 5, and a flow meter 6; the material box 2 is connected to the outlet of the hopper 1; the The screw pump 3 is arranged inside the material box 2, and the grout outlet of the screw pump 3 extends out of the material box 2; the grouting pipe 4 is connected with the grout outlet of the screw pump 3; the pressure sensor 5 is arranged on the grouting pipe 4; the flow meter 6 is set between the screw pump 3 and the grouting pipe 4.

[0039] An intelligent sleeve grouting device with an assembled structure in this embodiment, when in use, the slurry is injected into the material box 2 from the outlet of the hopper 1, and is discharged from the grouting pipe 4 through ...

Embodiment 2

[0048] This embodiment provides a construction method for the prefabricated structure intelligent sleeve grouting device described in Embodiment 1, including the following steps:

[0049] S1, inject the slurry into the material box 2 through the hopper 1, start the screw pump 3 in the forward direction, grout the sleeve a of the assembled structure, and detect the flow rate and pressure of the slurry during the grouting process in real time through the pressure sensor 5 and the flow meter 6;

[0050] S2, set a blocking state judging pressure P1, the pressure of the slurry exceeds the blocking state judging pressure P1 and the flow rate of the slurry becomes smaller, repeatedly start the screw pump 3 forward and reverse several times, and then continue to start the screw pump 3 in the forward direction. The sleeve a of the structure is grouted;

[0051] S3, when the cumulative grouting amount of the flowmeter 6 reaches the required grouting amount of the sleeve a, the grouting ...

Embodiment 3

[0057] refer to figure 1 , figure 2 , Figure 4 , Fig. This embodiment provides another construction method for an assembled structure intelligent sleeve grouting device, including the following steps:

[0058] S1, dock the grouting port of the grouting pipe 4 with the grouting port of the sleeve a, connect the third port of the tee 14 with the grouting port of the sleeve a; open the first valve 8 and the second valve 9; Close the third valve 10, the pumping device 12;

[0059] S2, inject the slurry into the material box 2 through the hopper 1, start the screw pump 3 in the forward direction, grout the sleeve a of the assembled structure, and detect the flow and pressure of the slurry during the grouting process in real time through the pressure sensor 5 and the flow meter 6;

[0060] S3, when the sleeve a is blocked, close the first valve 8 and the second valve 9; open the third valve 10 and the pumping device 12;

[0061] S4, when the sleeve a is unblocked, reopen the f...

Abstract

The purpose of the present invention is to provide an assembled structure intelligent sleeve grouting device and construction method, aiming at the deficiencies of the prior art, through real-time monitoring of data such as grouting pressure, flow rate and flow rate, intelligently judge the grouting state and make corresponding grouting adjustments Measures to ensure the quality of grouting. An intelligent sleeve grouting device with an assembled structure, including a hopper, a material box, a screw pump, a grouting pipe, a pressure sensor, and a flow meter; the material box is connected to the outlet of the hopper; the screw pump is arranged inside the material box , the grout outlet of the screw pump stretches out of the material box; the grouting pipe is connected with the grout outlet of the screw pump; the pressure sensor is arranged at the grout outlet of the grouting pipe; the flow meter is arranged between the screw pump and the between the grouting pipes.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to a prefabricated structure intelligent sleeve grouting device and a construction method. Background technique [0002] With the continuous advancement of national policies, prefabricated buildings have become the key development direction of the construction industry. The effective connection between the prefabricated components of the prefabricated building is the key to ensure the safety and quality of the prefabricated structure. [0003] Existing connection methods include sleeve grouting connection, grout anchor lap joint, sleeve extrusion connection, etc. Although the sleeve grouting connection is more commonly used, due to the complex operation of the sleeve grouting construction, the uneven quality of the construction personnel, and the difficulty of visual inspection of the construction quality, the grouting is often not full, which also brings difficulties to the ...
