Description

Technical Field

[0001] This utility model belongs to the field of bridge construction technology, and more specifically, it relates to a reinforcement and support device for foundation construction. Background Technology

[0002] As the foundation engineering in bridge engineering, pile foundation engineering can transfer the load of the bridge to the soil layer with good bearing capacity at a deeper underground level to meet the requirements of bearing capacity and settlement. Drilled cast-in-place piles are one of the more common types of bridge pile foundations. When drilling pile foundations, a pile foundation casing is placed on the top of the pile hole to protect the pile body and prevent soil collapse and pile hole deformation. Existing pile foundation casings are generally tubular structures made of materials such as steel cylinders or plastic cylinders.

[0003] Existing application number: CN202222023444.X, this utility model discloses a bridge pile foundation construction casing, including a pile foundation casing body and an adjustable push plate. A positioning block is provided at the upper end of the inner wall of the pile foundation casing body. The adjustable push plate is connected to a fixed threaded port via a long adjusting bolt and is located inside the positioning block. A cylinder opening reinforcement strip is provided at the lower end of the inner wall of the pile foundation casing body. A guide block is provided at the middle of the inner wall of the pile foundation casing body, aligned with the positioning block. A guide opening is provided below the guide block. In this utility model, four rows of telescopic hooks are provided in four directions inside the pile foundation casing body, and each row of telescopic hooks is assembled into one unit via the adjustable push plate. By loosening the long adjusting bolt at the top, the adjustable push plate can be raised to an obliquely upward position, causing each telescopic hook to retract inside the guide opening, keeping the outer wall of the pile foundation casing body smooth, facilitating the hammering of the pile foundation casing body into the soil layer.

[0004] Based on the above, after the casing is inserted into the top of the pile hole, in order to ensure that it is accurately aligned with the design coordinates of the pile foundation, it is usually necessary to pull a rope to mark the center position of the casing. This process is not only cumbersome, but if a deviation in the position of the casing is found during the measurement process, the casing must be pushed to adjust its position. During this process, the rope is very easy to break or shift due to excessive force, which will make it necessary to pull it again. This undoubtedly increases the complexity and time cost of the operation. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a reinforcement support device for foundation construction. This addresses the issue that, in existing methods, after the casing is inserted into the top of the pile hole, to ensure its precise alignment with the design coordinates of the pile foundation, it is typically necessary to use a string to mark the center position of the casing. This process is not only cumbersome, but also requires pushing the casing to adjust its position if a deviation is found during measurement. During this process, the string is prone to breaking or shifting due to excessive force, necessitating re-stringing, which undoubtedly increases the complexity and time cost of the operation.

[0006] The purpose and effect of this utility model's reinforcement and support device for foundation construction are achieved through the following specific technical means:

[0007] A reinforcement and support device for foundation construction includes a casing body;

[0008] Mounting box, which is fixedly connected to the front top of the casing body;

[0009] A control knob is rotatably connected to the front of the mounting box;

[0010] Two sliding connectors are provided, and the two sliding connectors are slidably connected to the top of the protective cylinder body;

[0011] The positioning and holding components are provided in two pieces, and the two positioning and holding components are respectively fixedly connected to the inner side of two sliding connecting components;

[0012] The connecting rod is provided in two parts, and the two connecting rods are respectively fixedly connected to the outside of the two sliding connecting parts;

[0013] A drilling positioning assembly is disposed inside the mounting box;

[0014] A fixed-point mapping component is disposed inside two positioning and holding components.

[0015] Furthermore, the drilling positioning assembly includes:

[0016] A transmission worm gear, which is coaxially and fixedly connected to the back of the control knob;

[0017] A first drive shaft is rotatably connected inside the mounting box;

[0018] A transmission worm gear is coaxially and fixedly connected to the top of the first transmission shaft, and the transmission worm gear meshes with the transmission worm.

[0019] Furthermore, the drilling positioning assembly also includes:

[0020] A transmission gear, which is coaxially and fixedly connected to the lower part of the first transmission shaft;

[0021] The transmission rack consists of two racks, which are slidably connected inside the mounting box. The outer ends of the two racks are fixedly connected to the inner sides of two connecting rods, and the two racks mesh with transmission gears respectively.

[0022] Furthermore, the fixed-point mapping component includes:

[0023] A connecting shaft is provided, and two connecting shafts are respectively rotatably connected to the top of two positioning and holding members;

[0024] The rotating plate consists of two pieces, with the outer ends of the two rotating plates respectively fixedly connected to the outer sides of the two connecting shafts.

[0025] Furthermore, the fixed-point mapping component also includes:

[0026] The placement slots are provided, and two placement slots are provided, which are respectively provided on the inner side of the two rotating plates.

[0027] Furthermore, the fixed-point mapping component also includes:

[0028] The first positioning magnet is provided in two sets, with two first positioning magnets in each set. The two sets of first positioning magnets are respectively fixedly connected to the inside of two rotating plates.

[0029] The second positioning magnet is provided in two sets, with two pieces in each set. The two sets of second positioning magnets are respectively fixedly connected inside the two positioning and holding pieces.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] First, after adjusting the position of the casing, move the drill bit to the top of the casing. Then, turn the operating knob to move the two positioning and holding parts inward at the same time. After that, adjust the drill bit to a state that is close to but not in contact with the inner side of the two positioning and holding parts. This ensures that the drilling position is as close as possible to the center of the casing, effectively improving the accuracy of the pile foundation position and reducing errors.

[0032] Secondly, after flipping the rotating plate to the open state, the circle formed by the two placement slots is the center of the main body of the casing. At this time, by inserting an RTK measuring device into the placement slot, the coordinates of the center can be quickly determined without the need for stringing, making the operation highly efficient. The rotating plate can be magnetically attached and securely stored in the positioning and holding parts to avoid accidental flipping, ensuring construction accuracy and efficiency.

[0033] This invention allows two positioning and holding components to move inward by operating a knob, ensuring that the drill bit is close to the center of the casing, thus improving the accuracy of pile foundation construction and reducing errors. By flipping the rotating plate to the open state, the center coordinates can be quickly determined through the placement slot, eliminating the need for string lines and making the operation highly efficient. The rotating plate can be magnetically attached to the positioning and holding components to prevent accidental flipping, thereby improving construction quality and progress and providing strong support for pile foundation construction in bridge engineering.

Detailed Implementation

[0041] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0042] Example 1:

[0043] As attached Figure 1 To be continued Figure 5 As shown:

[0044] This utility model provides a reinforcement and support device for foundation construction, including a protective casing body 1;

[0045] Mounting box 2 is fixedly connected to the front top of the casing body 1;

[0046] Control knob 3 is connected to the front of mounting box 2 when rotated.

[0047] Sliding connector 4, two sliding connectors 4 are provided, and the two sliding connectors 4 are slidably connected to the top of the protective casing body 1;

[0048] Positioning and holding member 5, two positioning and holding members 5 are provided, and the two positioning and holding members 5 are respectively fixedly connected to the inner side of the two sliding connecting members 4;

[0049] Two connecting rods 401 are provided, and the two connecting rods 401 are respectively fixedly connected to the outside of the two sliding connecting parts 4;

[0050] Drilling positioning component, which is located inside mounting box 2.

[0051] The drilling positioning component includes:

[0052] The transmission worm gear 6 is coaxially and fixedly connected to the back of the control knob 3;

[0053] The first drive shaft 7 is rotatably connected inside the mounting box 2;

[0054] The transmission worm gear 701 is coaxially and fixedly connected to the top of the first transmission shaft 7. The transmission worm gear 701 meshes with the transmission worm 6. The function is that rotating the control knob 3 can drive the first transmission shaft 7 to rotate through the worm gear transmission mechanism formed by the meshing of the transmission worm gear 701 and the transmission worm 6.

[0055] The drilling positioning assembly also includes:

[0056] The transmission gear 702 is coaxially and fixedly connected to the underside of the first transmission shaft 7.

[0057] The transmission rack 8 consists of two racks, which are slidably connected inside the mounting box 2. The outer ends of the two racks are fixedly connected to the inner sides of the two connecting rods 401. The two racks mesh with the transmission gears 702. The effect is that when the first transmission shaft 7 rotates, the gear and rack transmission mechanism formed by the meshing of the two racks and the transmission gears 702 will drive the two connecting rods 401 to move inward or outward simultaneously. This will cause the two positioning and holding parts 5 to engage or disengage through the two sliding connecting parts 4.

[0058] The specific usage and function of this embodiment are as follows:

[0059] After adjusting the position of the casing body 1, first move the drill bit of the drilling rig to the top of the casing body 1, and then turn the control knob 3. The worm gear transmission mechanism formed by the meshing of the transmission worm 701 and the transmission worm 6 drives the first transmission shaft 7 to rotate. The rotation of the first transmission shaft 7 will drive the two connecting rods 401 to move inward simultaneously through the gear and rack transmission mechanism formed by the meshing of the two transmission racks 8 and the transmission gear 702. Thus, the two sliding connecting parts 4 will drive the two positioning and holding parts 5 to engage inward. By moving the drill bit of the drilling rig to a state that is as close as possible to the two positioning and holding parts 5 without contacting them, the position of the drill bit when drilling can be as close as possible to the center of the casing body 1, making the subsequent pile foundation pile position more accurate.

[0060] Example 2:

[0061] Based on Example 1, as shown in the appendix Figure 1To be continued Figure 5 As shown, it also includes a fixed-point mapping component, which is set inside the two positioning and holding components 5.

[0062] The fixed-point surveying component includes:

[0063] Two connecting shafts 9 are provided, and the two connecting shafts 9 are respectively rotatably connected to the top of the two positioning and holding parts 5;

[0064] Two rotating plates 10 are provided. The outer ends of the two rotating plates 10 are respectively fixedly connected to the outside of the two connecting shafts 9. The function is that the two rotating plates 10 can be flipped upward and folded into the two positioning and holding parts 5 or flipped downward and opened through the two connecting shafts 9.

[0065] The fixed-point mapping component also includes:

[0066] Placement slots 1001 are provided, and two placement slots 1001 are provided. The two placement slots 1001 are respectively provided inside the two rotating plates 10. The purpose of this is that the circle formed by the two placement slots 1001 is the center of the protective casing body 1. By inserting the measuring rod of the RTK measuring device into the two placement slots 1001, the coordinates of the center of the protective casing body 1 can be quickly determined.

[0067] The fixed-point mapping component also includes:

[0068] The first positioning magnet 1002 is provided in two sets, with two first positioning magnets 1002 in each set. The two sets of first positioning magnets 1002 are respectively fixedly connected to the inside of the two rotating plates 10.

[0069] The second positioning magnet 11 is provided in two sets, with two pieces in each set. The two sets of second positioning magnets 11 are fixedly connected inside the two positioning and holding parts 5. The effect is that, through the attraction of the two sets of first positioning magnets 1002 and the two sets of second positioning magnets 11, the two rotating plates 10 can be retracted into the two positioning and holding parts 5, and will not easily flip open, making the position more stable.

[0070] The specific usage and function of this embodiment are as follows:

[0071] After the casing body 1 is placed into the pile hole, the control knob 3 is rotated to move the two positioning and holding parts 5 inward and fit together. Then, through the two connecting shafts 9, the two rotating plates 10 can be flipped upward and retracted into the two positioning and holding parts 5, or flipped downward and opened. The circle formed by the two placement slots 1001 is the center of the casing body 1. By inserting the measuring rod of the RTK measuring equipment into the two placement slots 1001, the coordinates of the center of the casing body 1 can be quickly determined. Then, the position of the casing body 1 can be slightly moved using machinery. Adjust until the coordinates of the center of the casing body 1 coincide with the design coordinates of the pile foundation. No ropes need to be laid during the process, making the operation more efficient. After determining the position of the casing body 1, retract the two rotating plates 10 upwards. Through the attraction of the two sets of first positioning magnets 1002 and two sets of second positioning magnets 11, the two rotating plates 10 can be more securely retracted into the two positioning and holding parts 5, and will not easily flip open. Then, the control knob 3 can be rotated in the opposite direction to control the two positioning and holding parts 5 to separate outwards, and then the drilling rig can be lowered.
