Problems solved by technology

[0003] Due to the particularity of the semi-grouting sleeve, it is difficult to check the fullness of the grouting after the grouting is completed
At the same time, even if it is found that the half-grouting sleeve is not full, it is difficult to fill it
Therefore, the insufficiency of the half-grouting sleeve will cause huge safety hazards and lead to direct economic losses

Embodiment 1

[0028] like Figure 1-3 As shown, the present invention provides a device for inspecting the fullness of a semi-grouting sleeve, which includes a vent plug 1, a detection tube 2, a slurry outlet plug 3 and an industrial endoscope, and the slurry outlet plug 3 It is in the shape of a truncated cone and has a horizontal through hole on the upper side, and a truncated circular through hole on the lower side. The smaller end of the truncated circular through hole is set on the side with a larger diameter of the plug of the pulp outlet; The air vent plug 1 is arranged in the frustum-shaped through hole of the pulp outlet plug 3; the detection tube 2 is arranged in the horizontal through hole of the pulp outlet plug 3, and The end at the corner is set horizontally upwards, and the detection tube 2 has a detachable airtight seal at the end outside the grout outlet plug, which can effectively prevent the grout from entering the detection tube 2 during grouting, resulting in failure of...

Embodiment 2

[0037] like Figure 4 and Figure 5 As shown, the difference between this embodiment and Embodiment 1 lies in the detection tube 2, and the other end of the detection tube 2 in this embodiment is flush with the inner side of the pulp outlet plug.

Abstract

The invention discloses a semi-grouting sleeve fullness inspection device and a using method. The device includes a slurry outlet plug, a vent hole plugging matter, a test tube and an industrial endoscope, wherein the slurry outlet plug is in the shape of a truncated cone and has a horizontal through hole on the upper side, a truncated through hole is on the lower side, a smaller end of the truncated through hole is disposed on the side of the slurry outlet plug with the larger diameter, the vent hole plugging matter is embedded in the truncated through hole below the slurry outlet plug, the test tube is disposed in a horizontal through hole of the slurry outlet plug at an upper portion, the test tube has a detachable airtight seal at one end of the outer side of the slurry outlet plug, the other end of the test tube has an opening, the industrial endoscope can be detected by the test tube extending into the interior of a semi-grouting sleeve. The device is advantaged in that after grouting, the fullness inside the grouting sleeve can be quickly, intuitively and reliably detected, moreover, in the case of finding that grouting is not full, the semi-grouting sleeve can be filled with grouting on site, and check can be performed another time.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to a device for checking the fullness of a half-grouting sleeve and a method for using it. Background technique [0002] With the promotion and application of prefabricated structures in my country, semi-grouting sleeves are widely used in the connection between prefabricated components of prefabricated structures. The grouting fullness of the half-grouting sleeve directly determines the connection strength between components and the overall safety of the building. [0003] Due to the particularity of the semi-grouting sleeve, it is difficult to check the fullness of the grouting after the grouting is completed. At the same time, even if it is found that the half-grouting sleeve is not full, it is difficult to fill it. Therefore, the insufficiency of the half-grouting sleeve will cause huge safety hazards and lead to direct economic losses. [0004] Therefore, there is an u...
