Description

Technical Field

[0001] The present invention relates to the technical field of underground continuous wall construction devices, and in particular to an underground continuous wall groove wall reinforcement device and method for an ultra-deep foundation pit. Background Art

[0002] An underground continuous wall is a foundation project that uses a trenching machine on the ground to dig a long and narrow deep trench along the peripheral axis of the deep excavation project under the condition of mud wall protection. After the trench is cleared, a steel cage is hung in the trench, and then underwater concrete is poured using the conduit method to form a unit trench section. This process is carried out section by section to build a continuous reinforced concrete wall underground as a water-cutting, anti-seepage, load-bearing and water-retaining structure. If the trench wall collapses after the trench is formed, it will make it impossible to continue construction, greatly affecting the construction progress. Therefore, the trench wall needs to be reinforced after the trench is formed.

The bottom of the side panel is serrated, and the two ends of the side panel and one end of the adjacent flange panel are respectively connected in sequence through the flange panel and side panel plug-in mechanisms to form a groove wall side panel assembly with a length matching the length of the underground continuous wall groove wall; the two ends of the web panel and the middle of the corresponding flange panel are respectively vertically connected through the side panel and web panel plug-in mechanisms; although this patent can reinforce the continuous wall groove wall, it is inconvenient to take and place during reinforcement, and the reinforcement efficiency is low.

[0045] An ultra-deep foundation pit underground continuous wall trench reinforcement device is provided in the embodiment, such as Figures 1 to 5 and Figures 11 to 14As shown, the first position adjustment assembly 6 includes four groups of lifting adjustment mechanisms installed on the support base 1, and the four groups of lifting adjustment mechanisms are symmetrically distributed on the flip plate side of the support base 1. Each group of lifting adjustment mechanisms includes a sliding frame 601, a lifting rod 602, a third screw 603, a fourth motor 604, a fifth motor 605, and a rotating drum 606.

[0047] When the device of the present invention is in use, the flip plate 205 only needs to enter the continuous wall groove body at the lower part, and does not need to go down completely. The distance of the flip plate 205 is less than the height of the first reinforcement plate - a. When the flip plate drops to a height of b, the first reinforcement plate 301 drops by a distance a+b. That is, when the flip plate 205 drops to the bottom, the first reinforcement plate 301 has a distance that is completely dropped to the continuous wall groove body.

[0048] The working principle of the present invention is as follows: when the first position adjustment component is working, the output shaft of the fifth motor 605 drives the sliding frame 601 to move through the third screw 603, the sliding frame 601 drives the lifting rod 602 to move, and the output shaft of the fourth motor 604 drives the rotating drum 606 to rotate.

[0049] When the flip unit is working, the output shaft of the first motor 202 drives the flip plate 205 to rotate through the first connecting shaft 203, thereby changing the placement state of the flip plate 205; when the first reinforcement unit is working, the output shaft of the third motor 302 drives the second lead screw 303 to rotate, and when the second lead screw 303 rotates, it drives the second reinforcement plate 401 and the third reinforcement plate 403 to move horizontally; when the second reinforcement unit is working, the piston rod of the first electric cylinder 402 drives one first reinforcement plate 301 to move through the third reinforcement plate 403, and the piston rod of the second electric cylinder 404 drives another first reinforcement plate 301 to move through the second reinforcement plate 401, and the two first reinforcement plates 301 move toward or oppositely to adjust the distance between the two first reinforcement plates.

[0050] The reinforcement assembly is clamped on the flipping unit through the clamping unit, and the flipping unit flips the reinforcement assembly from a horizontal state to a vertical state; the first position adjustment assembly drives the flipping unit to move through the first support frame 201, and the flipping unit drives the reinforcement assembly to move into the continuous wall groove through the clamping unit; the lifting unit drives the reinforcement assembly to continue to descend in the continuous wall groove through the clamping unit, so that the reinforcement assembly is completely placed in the continuous wall groove, the clamping unit releases the reinforcement assembly, and the first position adjustment assembly and the second position adjustment assembly return to the initial position, and the first position adjustment assembly and the second position adjustment assembly are both away from the reinforcement assembly. The first electric cylinder 402 pushes the first reinforcing plate 301 through the third reinforcing plate 403, and the second electric cylinder 404 pushes the other first reinforcing plate 301 through the second reinforcing plate 401, so that the two first reinforcing plates 301 support the two groove surfaces of the continuous wall groove, and the verticality of the groove wall is detected by multiple verticality measurement sensors on the first reinforcing plate 301; the third motor 302 drives the second reinforcing plate 401 and the third reinforcing plate 403 to move to the side of the first reinforcing plate 301 through the second lead screw 303, so that the second reinforcing plate 401 and the third reinforcing plate 403 support the other two groove surfaces of the continuous wall groove; when the continuous wall groove needs to be In front of the inner lower steel cage, the first electric cylinder 402 pushes the first reinforcement plate 301 to move in the opposite direction through the third reinforcement plate 403, and the second electric cylinder 404 pushes the other first reinforcement plate 301 to move in the opposite direction through the second reinforcement plate 401, so that the two first reinforcement plates 301 are respectively away from the two groove surfaces of the continuous wall groove, and the third motor 302 drives the second reinforcement plate 401 and the third reinforcement plate 403 to move in the opposite direction through the second lead screw 303, so that the second reinforcement plate 401 and the third reinforcement plate 403 are away from the other two groove surfaces of the continuous wall groove, and the reinforcement assembly is clamped by the clamping unit, and the reinforcement assembly is removed by the first position adjustment assembly and the second position adjustment assembly.

[0051] The embodiment provides a method for reinforcing the underground continuous wall trench wall of an ultra-deep foundation pit, which uses the above-mentioned ultra-deep foundation pit underground continuous wall trench wall reinforcement device for reinforcement, and specifically includes the following steps:

[0053] S2. The first position adjustment component is used to adjust the flip plate and the reinforcement component so that the flip plate and the reinforcement component are moved downward as a whole into the continuous wall groove to be reinforced. At this time, the first position adjustment component stops working.

[0054] S3. The lifting unit and the clamping unit of the second position adjustment component drive the reinforcement component to continue to descend in the continuous wall groove, so that the reinforcement component is placed in the continuous wall groove, and the clamping unit is controlled to release the reinforcement component. The first position adjustment component and the second position adjustment component return to the initial position. At this time, the first position adjustment component and the second position adjustment component are both away from the reinforcement component.

[0055] S4.
