[0014] Furthermore, reinforcing ribs are welded between the connecting plates of adjacent drill tubes.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] ① After the anchor pipe is anchored in the soil layer, grouting material is injected into the top of the track pipe. There are no large particles in the grouting material, and the grouting material has great fluidity. The grouting material is poured in from the top of the track pipe. After the bottom of the track pipe is filled, the grouting material enters the grouting pipe through the grouting pipe, and then flows into the anchor pipe, and finally flows out from the grouting hole. There are several grouting holes distributed on the side wall of the anchor pipe. After the grouting material flows out of the grouting hole, it wraps the anchor pipe and fills the gap between the anchor pipe and the borehole. When the grouting material reaches the connecting hole, grouting material will enter the drill barrel. With the increase of grouting material, the grouting material will eventually fill the borehole, drill barrel, track pipe and anchor pipe tightly.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-3 As shown, a foundation reinforcement device for civil engineering comprises: a drill tube 1 drilled into the foundation, a connecting hole 11 is opened on the side wall of the drill tube 1; a track tube 2 fixedly connected to the drill tube 1, a grouting hole 41 is opened on the top of the track tube 2, and a grouting hole 21 is opened on the side wall of the track tube 2; a connecting plate 12 fixedly connected to the side wall of the top of the drill tube 1; a connecting tube 3 fixedly connected to the side wall of the track tube 2; an anchoring tube 4 rotatably connected to the connecting tube 3, the top of the anchoring tube 4 is connected to the grouting hole 21 through a grouting tube 7, and a grouting hole 41 is opened on the side wall of the anchoring tube 4; a moving tube 5 slidably connected to the track tube 2; and a joystick 6 fixedly connected to the side wall of the moving tube 5.

[0025] The bottom of the drill barrel 1 is a conical head, and a spiral piece 13 is fixedly connected to the side wall of the bottom of the drill barrel 1. When installing the drill barrel 1, a hole is first drilled in a place where there is no pile in the foundation, and then the drill barrel 1 is placed in the drill hole. The drill barrel 1 is rotated to make the spiral piece 13 embedded in the soil layer, so that the drill barrel 1 is stably anchored in the foundation. After the drill barrel 1 is embedded, the connecting piece is located above the foundation.

[0026] The middle of the drill tube 1 is hollow, and the connecting hole 11 connects the inside of the drill tube 1 with the outside. The connecting hole 11 is a vertical hole, and the connecting holes 11 are arranged in a circular array on the side wall of the drill tube 1. A track tube 2 is welded at the bottom center of the hollow part of the drill tube 1, and the top of the track tube 2 is flush with the top of the drill tube 1.

[0027] Two moving tubes 5 are provided on the track tube 2, and a connecting tube 3 is provided under each moving tube 5. The outer diameter of the fixed tube is larger than the inner diameter of the connecting tube 3. When the moving tube 5 slides to the top of the connecting tube 3, the connecting tube 3 restricts the moving tube 5 from continuing to move downward, so that the moving tube 5 can only slide above the connecting tube 3.

[0028] Three first connection shafts 51 are welded to the side wall of the moving tube 5 . The three first connection shafts 51 are distributed in a ring array on the side wall of the moving tube 5 . The angle between the connected first connection shafts 51 is 120 degrees.

[0029] The anchoring tube 4 is arranged below the first connecting shaft 51, the first connecting shaft 51 and the anchoring tube 4 are in the same vertical plane, the outer side of the anchoring tube 4 is a connecting hole, the second connecting shaft 42 is welded to the side wall of the anchoring tube 4, the first connecting shaft 51 and the second connecting shaft 42 are connected by a connecting rod 9, the upper part of the connecting rod 9 is rotatably connected to the first connecting shaft 51, and the lower part of the connecting rod 9 is rotatably connected to the second connecting shaft 42.

[0030] The side wall of the connecting tube 3 is fixedly connected with a third connecting shaft 31 . Three third connecting shafts 31 are also provided on each connecting tube 3 . The three third connecting shafts 31 are respectively provided under each first connecting shaft 51 . The top side wall of the anchoring tube 4 is rotatably connected with the third connecting shaft 31 .

[0031] When the movable tube 5 is pressed down, the movable tube 5 moves vertically downward along the direction of the track tube 2, and the connecting rod 9 pushes the second connecting shaft 42 outward without moving. At the same time, the top of the anchor tube 4 rotates upward with the third connecting shaft 31 as the axis. At this time, the anchor tube 4 can extend out of the connecting hole 11. The length of the connecting hole 11 is greater than the length of the anchor tube 4. The anchor rod can be smoothly rotated out of the connecting hole 11. The front end of the anchor tube 4 is a conical head. After the anchor tube 4 extends out of the connecting hole 11, it is inserted into the inner wall of the borehole, so that the device can be more firmly installed in the borehole.

[0032] A joystick 6 is connected at the gap between the first connecting shafts 51. There are three joysticks 6 in total, which connect the upper and lower moving tubes 5. When the joystick 6 moves up and down, the two moving tubes 5 are lifted and lowered synchronously. When the anchor tube 4 does not protrude from the connecting hole 11, the distance between the moving tube 5 and the connecting tube 3 is relatively large. At this time, the top of the joystick 6 is higher than the top of the drill tube 1. A force plate 61 is welded on the top of the joystick 6. After the drill tube 1 is fixed, the force plate 61 is knocked to lower the joystick 6. The joystick 6 drives the moving rod to lower, and further makes the anchor tube 4 extend out of the connecting hole. When the force plate 61 is flush with the top of the track tube 2, the anchor tube 4 is embedded in the soil. A hole is provided in the middle of the force plate 61. The diameter of the hole is larger than the diameter of the track tube 2, and the track tube 2 can pass through the hole.

[0033] When the anchor tube 4 rotates outward, the moving track of the anchor tube 4 will leave track marks on the inner wall of the soil layer, and the diameter of the drill hole is slightly larger than the diameter of the drill tube 1. There is also a gap between the drill tube 1 and the drill hole. After the anchor tube 4 is anchored in the soil layer, grouting material is injected into the top of the track tube 2. There are no large particles in the grouting material, and the grouting material has great fluidity. The grouting material is poured in from the top of the track tube 2. After the bottom of the track tube 2 is filled, the grouting material enters the grouting pipe 7 through the grouting pipe, and then flows into the anchor tube 4, and finally flows out from the grouting hole 41. There are several grouting holes 41 distributed on the side walls of the anchor pipe 4. The grouting material flows out of the grouting holes 41 and wraps around the anchor pipe 4, filling the gap between the anchor pipe 4 and the borehole. When the grouting material reaches the connecting hole, the grouting material will enter the drill barrel 1. As the grouting material increases, the borehole, the drill barrel 1, the track pipe 2 and the anchor pipe 4 will be completely and tightly filled. After the grouting material solidifies, the drill barrel 1 and the anchor pipe 4 are completely and tightly anchored in the foundation, making the foundation soil more compact and enhancing the strength and bearing capacity of the foundation.

[0034] The grouting pipe 7 is a hose, and the grouting pipe 7 can follow the rotation of the anchoring pipe 4 .

[0035] After the grouting material solidifies, two reinforcing ribs 8 are welded on the connecting plate 12. The reinforcing ribs 8 connect the adjacent drill tubes 1 together. Finally, the reinforcing ribs 8 form two layers of steel mesh. When pouring the cushion layer, the height of the cushion layer concrete exceeds the connecting plate 12, so that the cushion layer has a stronger tensile and compressive resistance, further making the foundation more stable and reducing the settlement of the foundation in the later stage.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
