It should be noted that, in the absence of conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] See also Figures 1 to 3, the figure shows the preferred structure of the foundation treatment grouting device provided by the embodiment of the present invention. As shown in the figure, the foundation treatment grouting device includes: a moving device 1, a driving device 2, a positioning device 3, a grouting pipe 4 and an insert 5. Among them, the moving device 1 is used to be movable and can be fixed at any position. Specifically, the moving device 1 can be a mobile vehicle.

[0021] Preferably, the mobile device 1 comprises: a vehicle bucket 11, a connecting member 12 and a plurality of wheels 13. Each wheel 13 is rotatably disposed at the bottom of the vehicle bucket 11 ( Figure 1 The lower part shown in the figure), the connecting member 12 is arranged on one side of the bucket 11, and the connecting member 12 is used to be detachably connected with the traction device, so that the traction device tows the bucket 11 to move to any position to facilitate the movement of the bucket 11. In specific implementation, the connecting member 12 is bolted to the traction device.

[0022] The mobile device 1 is provided with a through opening along the longitudinal direction, wherein the longitudinal direction is Figure 1 The middle a direction is the direction from top to bottom. Specifically, the through opening is opened in the truck bucket 11, preferably at the center of the truck bucket 11.

[0023] The inserting member 5 and the driving device 2 can be movably arranged in the through hole, so that the inserting member 5 and the driving device 2 can be moved up and down in the through hole (relative to the Figure 1 In addition, the driving device 2 is placed above the inserting member 5 (relative to Figure 1 The driving device 2 contacts the plug-in member 5, and the driving device 2 is used to drive the plug-in member 5 downward (relative to Figure 1 The grouting hole is then drilled and inserted into the ground.

[0024] The interior of the insert 5 is hollow, and a plurality of through holes 51 are opened on the side wall of the insert 5. The grouting pipe 4 is partially inserted into the interior of the insert 5, that is, the end of the grouting pipe 4 is placed in the insert 5. The grouting pipe 4 is used to grout into the insert 5. The slurry flows into the soil layer through the through holes 51 in the insert 5, thereby completing the grouting.

[0025] Specifically, the insert 5 may include: a casing 52, a cover 53 and a drill bit 54. The top of the casing 52 ( Figure 2 The upper part of the casing 52 is open, and the top of the casing 52 is detachably connected to the cover 53, so that the casing 52 and the cover 53 can be opened and closed. Preferably, the cover 53 and the top of the casing 52 are threaded. The cover 53 is provided with an opening for the grouting pipe 4 to pass through, so that the end of the grouting pipe 4 is placed in the casing 52. The drill bit 54 is arranged at the bottom ( Figure 2 The drill bit 54 is drilled underground to facilitate drilling of the grouting hole. During specific implementation, the drill bit 54 is tapered.

[0026] In specific implementation, the casing 52 is cylindrical, the cover 53 is circular, and the outer diameter of the cover 53 is larger than the outer diameter of the casing 52. In this way, after the casing 52 is inserted into the ground, the cover 53 can play a blocking role, making it easy to pull the casing 52 out of the grouting hole.

[0027] After the grouting is completed, the external force device drives the driving device 2 to move upward, and the lifting device drives the plug-in 5 to move upward, so that the plug-in 5 is separated from the grouting hole. The positioning device 3 is arranged on the moving device 1. When the plug-in 5 is completely moved to be separated from the grouting hole, the positioning device 3 positions the plug-in 5, and the moving device 1 drives the plug-in 5 to move together. Specifically, the positioning device 3 is arranged on the top of the bucket 11 ( Figure 1 shown in the upper part).

[0028] Preferably, the driving device 2 includes: a pressure pump 21 and a pressure hammer 22. The pressure pump 21 is movably connected to the positioning device 3, and the pressure hammer 22 is connected to the pressure pump 21, and the pressure hammer 22 is in contact with the plug-in component 5. Both the pressure pump 21 and the pressure hammer 22 can move up and down in the through-hole, and the pressure pump 21 drives the pressure hammer 22 to move downward. Since the pressure hammer 22 is in contact with the cover body 53 in the plug-in component 5, the pressure hammer 22 drives the plug-in component 5 to move underground. After the grouting is completed, the external force device drives the pressure pump 21 and the pressure hammer 22 to move upward together, and the lifting device drives the plug-in component 5 to move upward, then the positioning device 3 positions the plug-in component 5, and since the pressure hammer 22 is in contact with the cover body 53 in the plug-in component 5, the positioning device 3 also positions the pressure pump 21 and the pressure hammer 22, thereby facilitating the overall movement.

[0029] During specific implementation, the pressure pump 21 and the pressure hammer 22 are both provided with channels in the longitudinal direction, and the channel of the pressure pump 21 is connected with the channel of the pressure hammer 22 , and the channel is used for the grouting pipe 4 to pass through.

[0030] Preferably, the driving device 2 includes: a pressure pump 21 and a pressure hammer 22; the pressure pump 21 is movably connected to the positioning device 3, and the pressure hammer 22 is connected to the pressure pump 21 and in contact with the plug-in component 5; and / or, the moving device 1 includes: a truck bed 11, a connecting piece 12 and a plurality of wheels 13; a through opening is provided in the truck bed 11, and the positioning device 3 is arranged at the top of the truck bed 11; each wheel 13 is rotatably arranged at the bottom of the truck bed 11; and the connecting piece 12 is arranged on one side of the truck bed 11.

[0031] It can be seen that in the present embodiment, the driving device 2 drives the plug-in component 5 to be inserted into the ground to drill grouting holes, and the grouting pipe 4 injects grout into the plug-in component 5 to realize grouting of the grouting holes to ensure the stability of the soil. After the grouting is completed, the plug-in component 5 and the driving device 2 can move upward relative to the through-hole, and the positioning device 3 can position the plug-in component 5. Since the driving device 2 is placed above the plug-in component 5, the positioning device 3 can also position the driving device 2 so that the plug-in component 5 is separated from the ground 15. The moving device 1 can drive the plug-in component 5, the driving device 2 and the positioning device 3 to move to any position together, so that the entire device can be reused and can be moved and transported. The entire device has a simple structure and is easy to operate, which improves the practical effect and construction efficiency, reduces the construction cost, and solves the problem that the soft soil layer construction equipment in the prior art is prone to low construction efficiency, high cost and cannot be reused. It can also be applicable to various foundations, even soft soil layer foundations, and can effectively improve the bearing capacity of soft soil layer foundations.

[0032] See also Figures 1 to 3 In the above embodiment, the positioning device 3 may include: a supporting mechanism and four positioning plates 31. The supporting mechanism is arranged on the mobile device 1, specifically, the supporting mechanism is arranged on the top of the bucket 11. The four positioning plates 31 are movably arranged on the supporting mechanism in a lateral direction, and the lateral direction is perpendicular to the longitudinal direction. Figure 2 The b direction in Figure 2 The four positioning plates 31 are arranged at intervals on the support mechanism, and preferably, the positioning plates 31 are evenly distributed on the support mechanism.

[0033] The inner side of each positioning plate 31 is arc-shaped. The four positioning plates 31 can move relative to the supporting mechanism. After the four positioning plates 31 move inward to be relatively close, the inner sides of the four positioning plates 31 are surrounded by a clamping space, and the insert 5 is clamped in the clamping space. When the four positioning plates 31 move outward, the four positioning plates 31 are separated, and the clamping space cannot be formed, and the insert 5 cannot be clamped. At this time, the insert 5 can move up and down relative to the through-hole, and then the grouting hole is drilled. Specifically, the clamping space is circular, and the circular diameter of the clamping space is smaller than the outer diameter of the cover body 53 in the insert 5. The cover body 53 is placed above the four positioning plates 31, and the four positioning plates 31 block the cover body 53, thereby realizing the positioning of the four positioning plates 31. More specifically, the circular diameter of the clamping space matches the outer diameter of the casing 52.

[0034] During specific implementation, the pressure pump 21 is movably connected to the supporting mechanism.

[0035] In specific implementation, the setting positions of the four positioning plates 31 on the supporting mechanism can be determined according to the position of the plug-in component 5 after it is separated from the grouting hole and the ground 15. As long as it can be ensured that the four positioning plates 31 can position the plug-in component 5 so that the plug-in component 5 is separated from the ground 15 and the plug-in component 5 can move with the moving device 1, this embodiment does not impose any restrictions on the positions of the four positioning plates 31.

[0036] It can be seen that in this embodiment, after the grouting is completed, the lifting device lifts the plug-in component 5 out of the grouting hole and makes the plug-in component 5 separate from the grouting hole and the ground 15. At this time, the four positioning plates 31 move inward laterally relative to the supporting mechanism to a matched state. The four positioning plates 31 clamp the casing 52 of the plug-in component 5 and block the cover body 53, thereby realizing the positioning of the cover body 53. The supporting mechanism supports the four positioning plates 31.

[0037] See also Figures 1 to 3 In the above embodiment, the support mechanism may include: four support frames 32 and four support columns 33. The cross section of each support frame 32 is L-shaped, and each support frame 32 has a preset height, which can be determined according to actual conditions, and this embodiment does not impose any restrictions on this.

[0038] The four support frames 32 are all disposed on the mobile device 1. Specifically, the bottoms of the four support frames 32 ( Figure 2 The lower part shown in the figure is connected to the top of the bucket 11. The four support frames 32 are spaced and symmetrically arranged, and the four support frames 32 form a support structure with a quadrilateral cross section. In addition, each support frame 32 is located at the four corners of the support structure. Specifically, the cross section of the support structure is a quadrilateral, and the positions of the four support frames 32 are respectively placed at the four corners of the quadrilateral cross section. There is a certain distance between any two adjacent support frames 32, and the distance can be determined according to actual conditions, and this embodiment does not impose any restrictions on this.

[0039] The four positioning plates 31 correspond to the four support frames 32 one by one, and each positioning plate 31 is movably disposed on the corresponding support frame 32 along the horizontal direction. Figure 2 The locating plates 31 are movably inserted into the corresponding openings, and each locating plate 31 is detachably connected to the support frame 32 after each locating plate 31 moves inward to align. Preferably, the detachable connection is a bolt connection. After the grouting is completed, the connection between each locating plate 31 and the corresponding support frame 32 is released, and each locating plate 31 is moved outward.

[0040] In a specific implementation, the opening of each support frame 32 is arranged close to the top of the support frame 32 , and the position of each opening corresponds to the position of the corresponding positioning plate 31 .

[0041] In order to ensure the accurate position of the four positioning plates 31, a baffle 34 is provided on the outside of each positioning plate 31, and the baffle 34 is perpendicular to the positioning plate 31, so that the positioning plate 31 and the baffle 34 form an L shape, and after each positioning plate 31 moves inward to match, each baffle 34 abuts against the corresponding support frame 32, and each baffle 34 is bolted to the corresponding support frame 32. In this way, the moving position of the positioning plate 31 is limited by the baffle 34, so that each positioning plate 31 is stably matched, and the connection between each positioning plate 31 and the corresponding support frame 32 is convenient.

[0042] In a specific implementation, the baffle 34 is disposed at a position on the positioning plate 31 such that when the baffle 34 abuts against the support frame 32 , the positioning plates 31 can be aligned together to form a clamping space with a circular cross-section.

[0043] The four support columns 33 are all arranged inside the support structure, that is, placed inside the space surrounded by the four support frames 32, and the four support columns 33 correspond to the four positioning plates 31 one by one. Figure 2 The lower end shown in the figure) is connected to the mobile device 1, and the second end ( Figure 2 The upper ends of the support columns 33 are in contact with the corresponding positioning plates 31, and each support column 33 is used to support the positioning plates 31 so that each positioning plate 31 is stable.

[0044] For specific implementation, see Figure 1 and Figure 2 The support mechanism may further include: a top cover 35. The top cover 35 is connected to the tops of the four support frames 32. The top cover 35 is provided with an opening that penetrates the thickness of the top cover. The size of the opening needs to match the size of the pressure pump 21 and the pressure hammer 22, or the size of the opening is larger than the size of the pressure pump 21 and the pressure hammer 22. The pressure pump 21 and the pressure hammer 22 are movably inserted into the opening. In this way, after the grouting is completed, the insertion member 5 is positioned by the four positioning plates 31, and the pressure pump 21 and the pressure hammer 22 can be inserted into the top cover 35, which is convenient for the placement of the pressure pump 21 and the pressure hammer 22.

[0045] During specific implementation, the pressure pump 21 is movably connected to the top cover 35 .

[0046] It can be seen that in this embodiment, the supporting mechanism has a simple structure, is easy to implement, and can provide stable support for each positioning plate 31 .

[0047] See also Figures 1 to 3In the above embodiments, a stabilizing protection component is provided between any two adjacent support frames 32 to ensure the stability between the two support frames 32 .

[0048] Each stable protection component may include: a protection net 6 and two diagonal braces 7. The two diagonal braces 7 are cross-arranged between two adjacent support frames 32, and the two diagonal braces 7 are arranged in a cross shape. The protection net 6 is arranged between two adjacent support frames 32, the two diagonal braces 7 and the mobile device 1. Specifically, the protection net 6 is arranged between the two adjacent support frames 32, the lower part of the two diagonal braces 7 and the mobile device 1. In this way, the stability and safety between the two adjacent support frames 32 can be effectively improved.

[0049] See also Figures 1 to 3 In the above embodiments, the foundation treatment grouting device may further include: four support plates 8. The cross section of each support plate 8 is L-shaped. The four support plates 8 correspond one to one with the four support frames 32. The mobile device 1 is provided with four penetration openings in the longitudinal direction, and the shape of each penetration opening is L-shaped. The four penetration openings are all placed on the outside of the through-opening, and the four penetration openings are evenly distributed along the circumference of the through-opening. Specifically, each penetration opening is opened in the truck bucket 11.

[0050] Each support plate 8 corresponds to each insertion opening one by one, and each support plate 8 can be slidably inserted into the corresponding insertion opening, that is, each support plate 8 can move up and down in the corresponding insertion opening. The four support plates 8 can be attached to the outer side of the corresponding support frame 32, and when each support plate 8 moves to the corresponding support frame 32, each support plate 8 is detachably connected to the corresponding support frame 32. Moreover, when each support plate 8 moves to contact the ground 15, each support plate 8 is detachably connected to the mobile device 1.

[0051] Preferably, each support plate 8 is connected to the corresponding support frame 32 by bolts. Specifically, each support plate 8 is provided with a bolt hole 10, and the corresponding support frame 32 is also provided with a bolt hole 10. The support plates 8 correspond to the bolt holes 10 on the support frames 32 and are connected by bolts.

[0052] In specific implementation, the number of bolt holes 10 on the support plate 8 and the number of bolt holes 10 on the support frame 32 can be determined according to actual conditions, and this embodiment does not impose any restrictions on this. In this embodiment, the number of bolt holes 10 on the support plate 8 and the number of bolt holes 10 on the support frame 32 are both three, and each bolt hole 10 on the support plate 8 corresponds to each bolt hole 10 on the support frame 32 one by one and both are connected by bolts.

[0053] Preferably, the side wall of the mobile device 1 is provided with a waist-shaped hole 9 corresponding to each penetration opening, and there are four waist-shaped holes 9, each waist-shaped hole 9 is connected with the corresponding penetration opening, and the waist-shaped hole 9 is opened from the side wall of the bucket 11 to the inside of the bucket 11 until it is connected with the penetration opening, and the vertical axis direction of the waist-shaped hole 9 is Figure 2 Direction a shown. Each support plate 8 is provided with a connection hole 81. When each support plate 8 moves to contact the ground 15, the connection hole 81 on each support plate 8 corresponds to the corresponding waist-shaped hole 9, and then connected by bolts, so that each support plate 8 is connected to the truck bucket 11. In this way, when each support plate 8 is connected to the waist-shaped hole 9 on the truck bucket 11, the bolt can adjust the position in the vertical axis direction of the waist-shaped hole 9, that is, the bolt can freely adjust the position within the range of the waist-shaped hole 9, and then adjust the relative position between each support plate 8 and the mobile device 1. Each support plate 8 can adjust the height of the mobile device 1 while supporting the mobile device 1.

[0054] In a specific implementation, the connection hole 81 on each support plate 8 may coincide with one of the bolt holes 10 on the support plate 8 .

[0055] It can be seen that in the present embodiment, by providing four support plates 8, each support plate 8 can support the mobile device 1, thereby improving the overall stability of the mobile device 1, and the waist-shaped holes 9 provided on the mobile device 1 enable the relative positions of each support plate 8 to be adjusted when connected to the mobile device 1, thereby adjusting the height of the mobile device 1 and ensuring the stable drilling of the grouting holes.

[0056] During specific implementation, a reinforcing plate 14 is provided on the ground 15 corresponding to the grouting hole, and the reinforcing plate 14 blocks the cover body 53 of the insert 5 .

[0057] Combination Figures 1 to 3 The method of using the foundation treatment grouting device is introduced as follows: the truck bucket 11 is moved to the desired position, and the positioning device 3 releases the positioning of the casing 52, that is, the positioning of the pressure pump 21 and the pressure hammer 22 is released. The four support plates 8 are disconnected from the four support frames 32, and the four support plates 8 slide in the corresponding penetration openings until they contact the ground 15. Each support plate 8 is bolted to the waist-shaped hole 9 on the truck bucket 11, so that each support plate 8 is relatively fixed to the truck bucket 11, thereby supporting the truck bucket 11. Since the pressure hammer 22 is in contact with the cover body 53, the pressure pump 21 drives the pressure hammer 22 to move downward, and the pressure hammer 22 collides and pressurizes the cover body 53, so that the casing 52 is inserted into the ground to drill the grouting hole. One end of the grouting pipe 4 is placed outside the pressure pump 21, and the grouting pipe 4 is inserted through the pressure pump 21, the pressure hammer 22 and the cover body 53. The other end of the grouting pipe 4 is placed in the casing 52. The grouting pipe 4 injects slurry into the casing 52, and the slurry is injected into the soil layer through the through holes 51 on the casing 52.

[0058] After the grouting is completed, the external force device lifts the pressure pump 21 and the pressure hammer 22, and the lifting device lifts the casing 52, so that the casing 52 is completely separated from the grouting hole and the ground 15 and is suspended. At this time, the four positioning plates 31 are moved inward to a matched state, and the clamping space surrounded by the inner side of the four positioning plates 31 clamps the casing 52, and the four positioning plates 31 block the cover body 53, so that the casing 52 and the four positioning plates 31 are relatively fixed to prevent the casing 52 from falling downward. At this time, since the pressure hammer 22 is placed above the cover body 53, the four positioning plates 31 position the pressure hammer 22 and the pressure pump 21. Then, the baffles 34 on the outside of the four positioning plates 31 are bolted to the corresponding support frames 32. At the same time, the bolt connection between the four support plates 8 and the bucket 11 is released, and the four support plates 8 are moved upward to fit with the four support frames 32. The four support plates 8 correspond to the four support frames 32 one by one and are bolted. At this time, the bucket 11 is pulled to move, so that the entire foundation treatment grouting device can be moved. When it moves to other required positions, the above operation can be repeated.

[0059] To sum up, in this embodiment, the driving device 2 drives the plug-in component 5 to be inserted into the ground to drill grouting holes, and the grouting pipe 4 injects grout into the plug-in component 5 to realize grouting of the grouting holes to ensure the stability of the soil. After the grouting is completed, the plug-in component 5 and the driving device 2 move upward relative to the through-hole, and the positioning device 3 positions the plug-in component 5 so that the plug-in component 5 is separated from the ground 15.
