[0034] like Figure 1 and Figure 2As shown, the retaining wall crack grouting repair device provided in this embodiment includes: a grouting machine 100, an injection pipe 200, an injection head 300, and a sealing device 400; one end of the injection pipe 200 is connected to the grouting machine 100, and the other end of the injection pipe 200 is connected to the injection head 300; the sealing device 400 is connected to the injection head 300, and the sealing device 400 is adapted to the target wall surface 900 or the target crack 800; when the injection head 300 is inserted into the target crack 800, the sealing device 400 surrounds the grout injected from the injection head 300 into the target crack 800 along the extension direction of the target crack 800.

[0035] The grouting machine 100 can use a propeller to mix and transport the grout, so that the grout is delivered along the injection pipe 200 to the grouting head 300. The grout discharged from the grouting head 300 can be injected into the target crack 800. The sealing device 400 can be fixed by inserting into the target crack 800, and the sealing device 400 can prevent the grout from overflowing and flowing in a large area within the target crack 800. The sealing device 400 can also be fixed by adsorption or snapping onto a specific part of the target wall surface 900, and the sealing device 400 can be used to seal the outside of the target crack 800 to prevent the grout inside the target crack 800 from overflowing.

[0036] like Figure 1 , Figure 3 and Figure 4 As shown, in an optional embodiment, the sealing device 400 includes a baffle 410, which is spaced apart from the grouting head 300, and the baffle 410 has a blocking surface facing the grouting head 300. The baffle 410 can be inserted into the target crack 800, and the grout injected into the target crack 800 by the grouting head 300 is blocked by the blocking surface, thereby concentrating the grout in the area near the grouting head 300 inside the target crack 800 and preventing excessive grout spillage.

[0037] Furthermore, the baffle 410 has a tapered end that gradually narrows along the direction of insertion into the target crack 800. The tapered end easily enters the narrower target crack 800, and as the insertion depth of the baffle 410 increases, the two sides of the tapered end gradually abut against the inner wall of the target crack 800, thus allowing it to fit target cracks 800 of different widths.

[0038] Furthermore, at least two baffles 410 are provided, and the grouting head 300 is located between the two baffles 410, so that the grout can be concentrated between the two baffles 410, avoiding the grout from overflowing along the target crack 800 in a large area during the grouting process.

[0039] In an optional embodiment, the sealing device 400 includes a sheath 420 surrounding the grouting head 300; with the grouting head 300 inserted into the target crack 800, the sheath 420 abuts against the target wall surface 900. The sheath 420 may be made of materials such as rubber or silicone, and grout overflowing from the target crack 800 can be received by the sheath 420, thereby preventing grout from overflowing and slipping outwards.

[0040] Furthermore, the sleeve 420 is connected to the handle 430, which is sleeved on the injection pipe 200. The sleeve 420 and the handle 430 can be connected by adhesive, snap-fit ​​or threaded connection. The handle 430 is sleeved on and connected to the injection pipe 200. The sleeve 420 has an inner cavity surrounding the grouting head 300 and with a diameter larger than the outer diameter of the injection pipe 200. Grout overflowing from the target crack 800 can be collected in the sleeve 420.

[0041] like Figure 1 and Figure 2 As shown, the grouting machine 100 is mounted on the mobile frame 500, which can be equipped with wheels that support it on the ground and can also be equipped with handrails, so as to facilitate the movement of the retaining wall crack grouting repair device.

[0042] Furthermore, the grouting machine 100 or the mobile frame 500 is equipped with a take-up reel 600; the injection pipe 200 includes a delivery pipe 210 and an injection pipe 220, with the grouting machine 100, delivery pipe 210, injection pipe 220, and injection head 300 in sequential fluid communication, and the delivery pipe 210 wound on the take-up reel 600. The delivery pipe 210 is a flexible hose that can be wound on the take-up reel 600, and the injection pipe 220 can be a rigid pipe to support the injection head 300 to connect to the target crack 800.

[0043] See Figure 2 , Figure 3 and Figure 5 As shown, the conveying pipe 210 is connected to the grouting machine 100 via a connecting sleeve 230, wherein the conveying pipe 210 is connected to the connecting sleeve 230, and the connecting sleeve 230 is fitted onto the discharge port of the grouting machine 100. A control belt 510 is used to bind the connecting sleeve 230 so that the connecting sleeve 230 tightens the discharge pipe of the grouting machine 100. The control belt 510 has multiple slots 501 along its extension direction. A connecting block 520 is connected to one end of the control belt 510. An adjusting rod 530 is equipped with teeth or threads and is rotatably connected to the connecting block 520. The teeth or threads engage with the slots 501. By turning the adjusting rod 530, the multiple slots 501 can be engaged one by one with the teeth or threads, thereby adjusting the tension of the control belt 510.

[0044] like Figure 3 and Figure 4As shown, the movable frame 500 or the winding reel 600 is movably connected to the support frame 700, and the grouting pipe 220 is installed on the support frame 700.

[0045] In an optional embodiment, the support frame 700 can be adjusted in position by means of telescopic lifting or swinging relative to the winding reel 600, thereby changing the position of the grouting pipe 220, and thus adjusting the grouting head 300 to inject grout into the target position.

[0046] In this embodiment, the support frame 700 includes: a support plate 710, a movable plate 720, a binding strap 730, a stop plate 740, a support spring 750, and an operating rod 760; the support plate 710 is movably connected to the movable frame 500 or the winding reel 600, and the movable plate 720 is movably connected to the support plate 710; one end of the binding strap 730 is connected to the movable plate 720, and the grouting pipe 220 is bound between the movable plate 720 and the binding strap 730, and the other end of the binding strap 730 is clamped between the stop plate 740 and the movable plate 720; the operating rod 760 is connected to the stop plate 740, and the support spring 750 is connected between the movable plate 720 and the stop plate 740, and the support spring 750 has an elastic tendency to press the stop plate 740 against the binding strap 730.

[0047] The support plate 710 is movably connected to the movable frame 500 or the winding reel 600, allowing it to slide or rotate and be locked by friction or threaded fasteners. The movable plate 720 can slide or rotate relative to the support plate 710. The positions of the grouting pipe 220 can be adjusted by combining the movements of the support plate 710 and the movable plate 720, thereby adjusting the working position of the grouting head 300. When it is necessary to install or remove the grouting pipe 220, the operating lever 760 can be pulled to disengage the abutment plate 740 from the restraint belt 730. At this time, the grouting pipe 220 can be installed or removed between the movable plate 720 and the restraint belt 730. After releasing the operating lever 760, the support spring 750 drives the abutment plate 740 to press against the restraint belt 730, thereby keeping the restraint belt 730 in a restrained state on the grouting pipe 220.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
