Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, and more specifically, to a grouting pipe laying device for municipal engineering construction. Background Technology

[0002] Grouting reinforcement technology is an engineering technique that involves injecting concrete grout into loose soil or structural cracks under pressure to improve its integrity and strength through filling, penetration and consolidation. In municipal engineering road reinforcement, grouting reinforcement is often used to improve the strength of roads. When grouting roads, it is necessary to drill holes of the required depth using a drilling rig and then embed grouting pipes for grouting. Currently, most grouting and drilling integrated grouting and reinforcement drilling rigs are used to complete the work. The drill rod of the grouting and reinforcement drilling rig is hollow inside. After the drill rod completes the drilling, a concrete slurry delivery pipe is connected to the top of the drill rod. The concrete slurry is pumped into the drill rod through a delivery pump to grout the road interior. The application of this device effectively improves the efficiency of road reinforcement. However, due to the long length of the drill rod, the drill bit end is far from the device body, resulting in poor stability of the drill bit end. In the initial stage of drilling, when the rotating drill bit comes into contact with the hard road, the drill bit will bounce slightly, making it impossible to drill smoothly into the road. Moreover, the bouncing of the drill rod can cause damage to the connection between the drill rod and the device body. At the same time, when the drilling is completed and grouting is carried out, the concrete slurry will overflow from the gap between the drill rod and the drill hole, resulting in waste. Therefore, to address this problem, this application provides a grouting pipe embedding device for municipal engineering construction to meet the requirements. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a grouting pipe laying device for municipal engineering construction. By setting a stabilizing component to improve the stability of the drill rod and simultaneously sealing the borehole to reduce the amount of concrete grout overflow, the present invention solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A grouting pipe laying device for municipal engineering construction includes a grouting drill body, a drill rod inside the grouting drill body, a base fixedly connected to the bottom of the grouting drill body, a fixed bracket fixedly connected to the top of the grouting drill body, and a stabilizing component. The stabilizing component is used to stabilize the stability of the drill rod during operation and is connected to the fixed bracket.

[0006] In a preferred embodiment, the stabilizing component includes a stabilizing collar fixedly connected to one end of the fixed bracket, the stabilizing collar being sleeved on the outside of the drill pipe.

[0007] In a preferred embodiment, a connecting cone wheel is fixedly connected to the bottom of the stabilizing collar, a closed cone bag is sleeved on the outside of the connecting cone wheel, and a telescopic spring is fixedly connected inside the closed cone bag.

[0008] In a preferred embodiment, a rubber cone plug is fixedly connected to the bottom end of the closed cone bag, and a flow guide skirt is fixedly connected to the top end of the rubber cone plug.

[0009] In a preferred embodiment, the bottom of the rubber cone plug is fixedly connected to an annular base, and the top of the annular base is fixedly connected to a vertical skeleton, which is disposed inside the rubber cone plug.

[0010] In a preferred embodiment, the rubber cone plug is internally fixedly connected to an annular skeleton, which is fixedly connected to the vertical skeleton.

[0011] In a preferred embodiment, a thickened band is fixedly connected to the outer side of the rubber cone plug.

[0012] In a preferred embodiment, a base plate is fixedly connected to the bottom of the fixed bracket, and a bolt is inserted into the interior of the base plate, the bolt being threadedly connected to the base.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This utility model, by setting a stabilizing collar, can restrict the movement direction of the drill rod, so that the drill rod can only rotate inside the stabilizing collar. By limiting the drill rod by the stabilizing collar, and the stabilizing collar being close to the drill bit end of the drill rod, the stability of the drill rod during drilling can be effectively improved, and the phenomenon of drill rod jumping causing damage to the connection between the drill rod and the main body of the device can be avoided.

[0015] This invention utilizes a sealed cone bag and a rubber cone plug. The rubber cone plug can be inserted into the borehole to fill the gap between the drill rod and the borehole, significantly reducing the amount of concrete grout overflow. Furthermore, the rubber cone plug, combined with the vertical and ring-shaped skeletons, can increase strength while maintaining a certain degree of elasticity, thereby increasing the firmness of the rubber cone plug in the borehole and preventing it from coming out. The sealed cone bag can seal the top end of the rubber cone plug after grouting is completed, and the guide skirt can prevent sewage and other impurities from entering the borehole and affecting the quality of the concrete grout, as well as the phenomenon of reduced concrete grout setting speed.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Refer to the instruction manual appendix Figure 1 As shown in the figure, a grouting pipe laying device for municipal engineering construction according to an embodiment of the present invention includes a grouting drill body 1, a drill rod 2 inside the grouting drill body 1, a base 3 fixedly connected to the bottom of the grouting drill body 1, a fixed bracket 4 on the top of the grouting drill body 1, a base plate 15 fixedly connected to the bottom of the fixed bracket 4, a bolt 16 inserted inside the base plate 15, the bolt 16 being threadedly connected to the base 3, the fixed bracket 4 being connected to the base 3 by the bolt 16, facilitating the assembly and disassembly of the fixed bracket 4, and a stabilizing component, which is used to stabilize the stability of the drill rod during operation. The stabilizing component is connected to the fixed bracket 4 and includes a stabilizing collar 5 fixedly connected to one end of the fixed bracket 4, the stabilizing collar 5 being sleeved on the outside of the drill rod 2, the stabilizing collar 5 having an annular structure, the inner diameter of the stabilizing collar 5 being adapted to the outer diameter of the drill rod 2, and the drill rod 2 being able to rotate inside the stabilizing collar 5.

[0024] It should be noted that the stabilizing collar 5 restricts the movement direction of the drill rod 2, allowing it to rotate only inside the stabilizing collar 5. To reduce friction between the drill rod 2 and the stabilizing collar 5, lubricating oil or other friction-reducing liquids can be applied to the inside of the stabilizing collar 5 during use. When installing the drill rod 2 inside the stabilizing collar 5, it can be raised by starting the grouting drilling machine body 1. It is important to note that the drill bit should not be installed at the bottom of the drill rod 2 at this time. After raising the drill rod 2 to a certain height, it is secured with bolts 16. The fixed bracket 4 is fixed to the top of the grouting drill body 1, so that the stabilizing collar 5 is concentric with the drill rod 2. This installation method is simple and convenient, and easy to disassemble, maintain and replace later. At this time, by starting the grouting drill body 1, the drill rod 2 is lowered, and the drill rod 2 can be inserted into the inner side of the stabilizing collar 5. After the drill bit is installed, drilling can be carried out. The stabilizing collar 5 limits the drill rod 2, and the stabilizing collar 5 is close to the drill bit end of the drill rod 2, which can effectively improve the stability of the drill rod 2 when drilling, and avoid the phenomenon that the drill rod 2 jumps and causes damage to the connection between the drill rod and the main body of the device.

[0025] Furthermore, such as Figures 2-5 As shown, a connecting conical wheel 6 is fixedly connected to the bottom of the stabilizing collar 5. A closed conical bag 7 is fitted onto the outer side of the connecting conical wheel 6. The outer contour of the connecting conical wheel 6 is conical, and the bottom diameter of the connecting conical wheel 6 is smaller than the top diameter, thus facilitating the fitting of the closed conical bag 7 onto the outer side of the connecting conical wheel 6. An annular groove is provided at the connection between the connecting conical wheel 6 and the closed conical bag 7, and the top part of the closed conical bag 7 can be engaged in the annular groove, thereby improving the stability of the connection between the closed conical bag 7 and the connecting conical wheel 6. The closed conical bag 7 is made of rubber and has a certain degree of elasticity. The maximum diameter of the port at the top of the closed cone bag 7 can be changed by telescopic expansion. The port at the top of the closed cone bag 7 is provided with pleats. The pleats are designed so that when the port at the top of the closed cone bag 7 is contracted to its minimum diameter, the pleats are in close contact, thereby sealing the port at the top of the closed cone bag 7. A telescopic spring 8 is fixedly connected inside the closed cone bag 7. The telescopic spring 8 is an elastic structure that can change its diameter by telescopic expansion. The telescopic spring 8 remains in a contracted state under normal conditions without force. The maximum diameter of the port at the top of the closed cone bag 7 can be changed by telescopic spring 8.

[0026] A rubber cone plug 9 is fixedly connected to the bottom end of the closed cone bag 7. The rubber cone plug 9 is a cone-shaped structure made of rubber. A flow guide skirt 10 is fixedly connected to the top end of the rubber cone plug 9. The flow guide skirt 10 is also cone-shaped and can guide sewage and other liquids away from the borehole. An annular base 11 is fixedly connected to the bottom of the rubber cone plug 9. The annular base 11 is made of metal and is easy to insert into the borehole. A vertical frame 12 is fixedly connected to the top of the annular base 11 and is located inside the rubber cone plug 9. The rubber cone plug 9 is internally fixedly connected to an annular skeleton 13, which is fixedly connected to the vertical skeleton 12. The vertical skeleton 12 and the annular skeleton 13 further enhance the strength of the rubber cone plug 9, making the rubber cone plug 9 more stable while having a certain elasticity. The diameter of the multiple annular skeletons 13 gradually decreases from top to bottom to match the taper of the rubber cone plug 9. The rubber cone plug 9 is fixedly connected to a thickened band 14 on the outside, which increases the maximum diameter of the rubber cone plug 9 in stages through multiple thickened bands 14.

[0027] It should be noted that when the drill rod is drilled into the road, because the maximum diameter of the drill bit is larger than the diameter of the drill rod 2, a gap will exist between the drill rod 2 and the borehole. By pressing down on the guide skirt 10, the rubber cone plug 9 is inserted into the borehole and continues until the guide skirt 10 is tightly attached to the road surface. Since the closed cone bag 7 is normally in a folded and retracted state, i.e. Figure 2 As shown, when the rubber cone plug 9 descends, the connecting cone wheel 6 is stretched and remains connected to the telescopic spring 8. The conical profile of the rubber cone plug 9 allows it to slightly contract after entering the borehole to fit tightly against it. The elasticity of the vertical skeleton 12 and the annular skeleton 13 increases the stability of the rubber cone plug 9 after it enters the borehole. Furthermore, the friction between the rubber cone plug 9 and the borehole is increased by multiple thickened bands 14, which further increases the tightness and firmness of the fit between the rubber cone plug 9 and the borehole. This significantly reduces the amount of concrete grout overflow during the grouting stage, thereby reducing waste.

[0028] After grouting is completed, the sealing cone bag 7 is separated from the connecting cone wheel 6 by pressing down, and the drill rod 2 is lifted to separate from the borehole, leaving the rubber cone plug 9 inside the borehole. At this time, the main body 1 of the grouting drill can be moved. At this time, the telescopic spring 8 loses the limit of the connecting cone wheel 6 and retracts, driving the top port of the sealing cone bag 7 to shrink until it is closed. Since the sealing cone bag 7 is relatively long, the top port of the sealing cone bag 7 can be kept from facing upwards, thus completing the sealing of the borehole and preventing impurities and sewage from entering the borehole through the port of the sealing cone bag 7. This avoids the phenomenon of reduced concrete slurry quality and reduced solidification speed in the borehole. At the same time, the guide skirt 10 guides sewage and other liquids to a position away from the edge of the borehole, further reducing the possibility of sewage entering the borehole. After the concrete slurry has solidified, the rubber cone plug 9 can be removed by lifting the sealing cone bag 7. The rubber cone plug 9 can be reused to reduce the cost of use.

[0029] When connecting the closed cone bag 7 to the connecting cone wheel 6, the telescopic spring 8 can be expanded to match the bottom diameter of the connecting cone wheel 6 by stretching the closed cone bag 7. Then, the port of the connecting cone wheel 6 can be pushed upward until the telescopic spring 8 is engaged in the annular groove of the connecting cone wheel 6 to complete the installation. The installation process is relatively simple and convenient.
