Description

Technical Field

[0001] This application generally relates to the field of building construction technology, and specifically to a layout device and its application. Background Technology

[0002] The anchorage is located on an alluvial island in the river. The bedrock depth in the project area exceeds 100m, and the thickness of the weak overburden layer exceeds 50m. It is mainly composed of silty clay with low strength and ground friction coefficient, poor plasticity, and high compressibility. There is no bearing layer that meets the requirements of traditional diaphragm walls. The sand layers near the bottom of the pit are all highly permeable and confined aquifers with high hydraulic head. There is no natural aquitard in the foundation. During the initial construction of the pit, the anchorage foundation plays a major anchoring role, and its bottom has high requirements for anti-sliding.

[0003] In the field of bridge construction, when using full-section deep ultra-high pressure jet grouting piles for reinforcement, more than 2,500 reinforcement piles are needed in an area with a depth of 54 meters. To achieve the desired reinforcement effect, high precision is required for the entire layout. Existing technologies are prone to errors during layout and cannot mark layout points. Furthermore, after the main unit is in place, due to the obstruction of the drill rod, the layout equipment can only verify the pile position by closely following the drill rod, leading to some errors in the verification. Therefore, controlling the overall layout accuracy is difficult. Summary of the Invention

[0049] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0050] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0051] Please see details. Figure 1-2 This application provides a stakeout apparatus, comprising:

[0052] The casing 10 and the base 20 disposed at the end of the casing 10, wherein the base 20 is provided with a construction opening 21 for installing the construction component 50;

[0053] An adjustment assembly 30 is disposed on the base 20. The adjustment assembly 30 includes a first adjustment sub-component 11 for adjusting the position of the construction component 50 at the construction opening 21, and a second adjustment sub-component 12 for adjusting the position of the construction component 50 along a first direction X and a second adjustment sub-component 12 for adjusting the position of the construction component 50 along a second direction Y.

[0054] The first adjustment component 11 includes a first guide rail portion 31 fixedly disposed on the base 20, a first sliding portion 32 slidably connected to the first guide rail portion 31, and a first pushing portion 33 in contact with the first sliding portion 32. The first pushing portion 33 is used to push the first sliding portion 32 to slide along the first direction X on the first guide rail.

[0055] The second adjustment component 12 includes a second guide rail portion 34 fixedly disposed on the first sliding portion 32, a second sliding portion 35 slidably connected to the second guide rail portion 34, and a second pushing portion 36 in contact with the second sliding portion 35. The second pushing portion 36 is used to push the second sliding portion 35 to slide along the second direction Y on the second guide rail.

[0056] The layout device provided in this embodiment can determine whether the construction component 50 has moved in the plane position and adjust the position of the construction component 50 on the construction opening 21 through the adjustment component 30 set on the base 20. It can realize high-precision plane control of ultra-high pressure jet grouting piles, ensure the accuracy of the construction pile position, facilitate the precise control of the layout plane deviation of the rotary drill rod in the reinforcement process and the precise control of the pile position in the reinforcement process, thereby ensuring the quality of full-section reinforcement and reducing the construction difficulty.

[0057] The casing 10 can be cylindrical, and the base plate is adapted to the shape of the casing 10. The base 20 can be circular. In specific installations, the base 20 is cut from a single piece of steel plate with a diameter greater than 8 cm than that of the casing 10. For example, the casing 10 has a diameter of 80 cm, and the base 20 has a diameter of 88 cm. To reduce weight, a construction opening 21 is cut into a 5 mm steel plate. In this embodiment, to facilitate the adjustment of the position of the construction component 50 on the construction opening 21 by the adjustment assembly 30, the construction opening 21 is located at the center of the base 20. The construction opening 21 is a rectangular opening. For example, the diameter of the jet grouting drill rod is 142 mm, and the allowable adjustment distance on each side along the first direction X and the second direction Y is 50 mm (the limit of control deviation). In this installation, the side length of the construction opening 21 is 25 cm. Furthermore, to improve control accuracy, the size of the central construction hole can be reduced, thereby reducing the allowable position value on each side, thus reducing the limitation of control deviation and achieving the effect of improving control accuracy.

[0058] like Figure 3 As shown, the base 20 is also provided with a plurality of keels 22. The keels 22 include one or more of the following: circular keels 221 arranged axially around the base 20, and strip keels 222 extending along a predetermined direction on the lower surface of the base 20. The strip keels 222 do not overlap with the construction opening 21. The circular keel 221 can be a ring of unequal angle steel welded around the base 20. The strip keel 222 can be a grid-shaped load-bearing frame angle steel welded to the lower surface of the base 20, forming an integral whole with the circular keel 221, thereby improving the strength of the base 20, reducing vibration, and improving control accuracy.

[0059] The base 20 is fixedly provided with a plurality of mounting components 40 that are fixedly connected to the protective sleeve 10. The plurality of mounting components 40 are arranged around the circumference of the protective sleeve 10. Each mounting component 40 includes a mounting part 41 fixedly connected to the base 20 and a mounting rod 42 rotatably connected to the mounting part 41. The mounting rod 42 is used to press against the protective sleeve 10.

[0060] The mounting part 41 can be a circular keel 221, and a tightening nut 43 is provided on the outer side of the circular keel 221. The mounting rod 42 can be a screw rod. By adjusting the position of the mounting rod 42 on the tightening nut 43, the base 20 and the protective sleeve 10 can be clamped together. For example, the base 20 is arranged with four fixed mounting components 40 at 90° intervals. In use, the entire device is fixed by tightening the mounting handle. Optionally, for easy movement and handling, a round steel handle is welded to the end of the mounting rod 42, and a handling handle can also be welded to the lower surface of the base 20.

[0061] To speed up the layout process, when installing the entire layout device, the X and Y axes can be aligned with the east and north of the layout component. In this application, the layout component achieves accurate layout by determining the difference between a point and the intended layout point on the X-axis (east) and Y-axis (north) and moving in that direction.

[0062] like Figure 4 As shown, the first guide rail 31 includes two first sliding shafts 301 fixedly disposed on both sides of the construction opening 21. The first sliding shafts 301 are parallel to the edge of the construction opening 21 disposed along the first direction X.

[0063] The first sliding shaft 301 can be a smooth screw, with one on each side of the first adjustment hole 305. The length is slightly longer than the side length of the central adjustment rectangular hole. Both ends are welded to the base 20 through the first support plate. The first sliding shaft 301 is welded to the top of the first support plate to provide the necessary space for the first support slider.

[0064] like Figure 5As shown, the first sliding part 32 includes a first base plate 302 and a first slider 303 fixedly disposed on the lower surface of the first base plate 302. The first slider 303 includes at least two first sliding blocks 304 that are slidably connected to the first sliding shaft 301 respectively. The first base plate 302 is provided with a first adjustment hole 305 corresponding to the construction port 21.

[0065] The first base plate 302 is made of a whole steel plate with holes. The steel plate is 39cm×25cm in size. A first adjustment hole 305 corresponding to the construction opening 21 is provided in the middle. The first adjustment hole 305 is a rectangular opening with a length of 28cm in the Y direction and a length of 17cm in the X direction. This hole is used to pass through the construction component 50, such as a high-pressure jet grouting drill rod (142mm) or a layout component.

[0066] The first sub-slider is sleeved on the first sliding shaft 301 with an opening diameter of 15mm, which is 1mm larger than that of the smooth screw. The opening position is required to be accurate so that it can be installed accurately. For example, the first sub-slider is divided into four parts, with two parts respectively set on the first sliding shaft 301 on both sides. The sub-slider is welded firmly to the first base plate 302, thereby supporting the first base plate 302 and allowing it to slide freely along the axial direction of the first sliding shaft 301.

[0067] The second guide rail 34 includes two second sliding shafts fixedly disposed on the upper surface of the first substrate 302. The two second sliding shafts are respectively disposed on both sides of the opening of the first adjustment hole 305. The second sliding shafts are parallel to the edge of the construction opening 21 disposed along the second direction Y.

[0068] like Figure 6 As shown, the second sliding part 35 includes a second base plate 312 and a second slider 313 fixedly disposed on the lower surface of the second base plate 312. The second slider 313 includes at least two second sliding blocks 314 respectively slidably connected to the second sliding shaft. The second base plate 312 is provided with a second adjustment hole 315 corresponding to the construction port 21.

[0069] The arrangement of the second guide rail 34 and the second sliding part 35 can refer to the arrangement of the first guide rail 31 and the second sliding part 35, and will not be repeated here.

[0070] It should be noted that in this embodiment, the second adjustment hole 315 corresponds to the first adjustment hole 305. The second adjustment hole 315 is a circular opening. For example, the second substrate 312 is made of a single piece of steel plate with dimensions of 25cm × 25cm. The opening is a circular hole with a diameter of 152mm, which is used to pass through the construction component 50, such as a high-pressure jet grouting drill rod (142mm) or a layout component, with a tolerance of ±5mm on each side. The diameter of the second adjustment hole 315 is smaller than that of the first adjustment hole 305. The second adjustment hole 315 facilitates the installation of the jet grouting drill rod while ensuring coaxiality with the high-pressure jet grouting drill rod. The first adjustment hole 305 and the construction hole facilitate the overall installation of the construction component 50 and the adjustment of its position on the construction port 21. When applied to the jet grouting process, the size of the second adjustment hole 315 allows for precise adjustment by the main power head to ensure that the jet grouting drill rod passes precisely through the second adjustment hole 315, thus ensuring that the deviation of the jet grouting drill rod is within the allowable deviation range.

[0071] The first pushing part 33 includes a first fixing box 321 fixedly connected to the first substrate 302 and a first screw 322 rotatably connected to the first fixing box 321; the first screw 322 extends along the first direction X, one end of the first screw 322 is provided with a first rotating head housed in the first fixing box 321, and the other end is provided with a first rotating handle.

[0072] The first fixing box 321 is welded from multiple small steel plates. The first fixing box 321 is fixedly connected to the first base plate 302 and fixed to one side of the first base plate 302 along the first direction X. Its function is to enclose the first rotating head on the first screw 322 so that the first rotating head can rotate freely in the fixing box. The first fixing box 321 is provided with a through hole for the first screw 322 to pass through. Through the limiting connection of the first fixing box 321 and the guiding effect of the first guide rail part 31 and the first sliding part 32, the rotation of the first screw 322 can be converted into the movement of the first base plate 302 along the first direction X.

[0073] The first screw 322 is provided with a first rotating handle for easy adjustment, thereby enabling the entire first adjusting sub-component 11 and the construction component 50 on it to move along the X-axis by freely rotating the screw to lengthen or shorten it, thereby achieving adjustment along the X-axis.

[0074] The second pushing part 36 includes a second fixing box 331 fixedly connected to the second substrate 312 and a second screw 332 rotatably connected to the second fixing box 331. The second screw 332 extends along the second direction Y. One end of the second screw 332 is provided with a second rotating head 333 housed in the second fixing box 331, and the other end is provided with a second rotating handle 334. The arrangement of the second pushing part 36 can refer to the arrangement of the first pushing part 33, and will not be described again in this application.

[0075] The substrate is provided with a first support part 13 that is rotatably connected to the first push rod. The first support part 13 is provided with a first threaded hole that mates with the first screw 322. When set up, the first support part 13 can be a support steel plate welded to a nut as a whole. The rotation of the first screw 322 can be converted into linear motion of the first substrate 302 along the first direction X through the first threaded hole on the nut, and drive the first slider 303 to move linearly on the first sliding shaft 301.

[0076] The substrate is provided with a second support portion 14 that is rotatably connected to the second push rod, and the second support portion 14 is provided with a second threaded hole that mates with the second screw 332. The arrangement of the second support portion 14 can refer to the arrangement of the first support portion 13, and will not be described again in this application.

[0077] In this embodiment, when the first rotating handle pushes the first screw 322 to rotate longer, it moves between the first rotating handle and the first support part 13; when the first rotating handle pushes the first screw 322 to rotate shorter, it moves between the first support part 13 and the first rotating head. The distance between the first support part 13 and the first fixing box 321 is used to limit the first adjustment distance of the construction component 50 along the first direction X on the construction opening 21. The distance between the first rotating handle and the first support part 13 is used to limit the second adjustment distance of the construction component 50 along the first direction X on the construction opening 21.

[0078] For example, the distance between the root of the first rotating head and the first support portion 13 is 5cm, the distance between the first rotating handle and the first support portion 13 is 10cm, and the distance between the first rotating handle and the first support portion 13 is also 5cm, thereby making the ±5cm control requirement a control limit.

[0079] It should be noted that the dimensions of the first adjustment distance and the second adjustment distance are not limited in the embodiments of this application. They can be set as needed in different embodiments. The distance between the root of the first rotating head and the first support part 13 is 3cm, the distance between the first rotating handle and the first support part 13 is 6cm, and the distance between the first rotating handle and the first support part 13 is also 3cm, so that the ±6cm control requirement is controlled by these.

[0080] Similarly, the distance between the second support portion 14 and the second fixing box 331 is used to limit the third adjustment distance of the construction component 50 along the second direction Y on the construction opening 21, and the distance between the second rotating handle 334 and the second support portion 14 is used to limit the fourth adjustment distance of the construction component 50 along the second direction Y on the construction opening 21.

[0081] In addition, the substrate is provided with a first clearance hole 15 that mates with the moving stroke and rotating stroke of the first rotating handle, and a second clearance hole 16 that mates with the moving stroke and rotating stroke of the second rotating handle 334. The first clearance hole 15 and the second clearance hole 16 facilitate the rotation of the first screw 322 and the second screw 332, making adjustment convenient.

[0082] In another embodiment of this application, such as Figure 7 As shown, the construction component 50 includes a layout component, and the layout device further includes a layout platform 61 detachably connected to the second base plate 312. The layout platform 61 is provided with a plurality of fixing blocks 60 arranged along the axial direction. The fixing blocks 60 are used to be detachably connected to the second adjustment hole 315. The layout platform 61 is provided with a layout port 62 corresponding to the second adjustment hole 315.

[0083] This application embodiment does not limit the number and shape of the fixing blocks 60. The shape of the lofting table 61 can be circular, and the shape of the fixing blocks 60 can be fixing teeth. Multiple fixing teeth arranged circumferentially are engaged and fixed on the second adjustment hole 315 for easy disassembly. For example, the lofting table 61 is welded from a 150mm diameter circular steel plate and three fixing blocks 60. A 2cm diameter circular hole is opened in the center of the circular steel plate as a lofting opening 62. Figure 8 As shown.

[0084] In addition, a layout stand (not shown) or a prism for total station layout can be installed on the base 20 as needed and fixed by connecting bolts. The layout stand is equipped with legs. The height of the legs can be adjusted as needed to adjust the instrument to a horizontal position, thereby achieving precise control of the vertical downward Z-axis of the layout component. This avoids unevenness of the top surface of the casing 10 or other installation factors that cause it to be non-horizontal, resulting in accuracy deviations in the layout.

[0085] The layout device provided in this application embodiment is suitable for bridge ultra-deep foundation reinforcement structures, especially for bridge ultra-deep foundations. By setting up a double-layer reinforcement body, the foundation reinforcement purpose can be achieved, forming an "artificial water-proof layer" with ultra-high reinforcement strength, a friction coefficient that meets the requirements, and a low permeability coefficient, thereby meeting the needs of anchorage diaphragm wall foundations for bearing layer, friction layer, and water-sealing layer.

[0086] The entire cross-section deep ultra-high pressure jet grouting piles were used for reinforcement. More than 2,500 reinforcement piles were arranged in a quincunx pattern in an area with a depth of 54 meters. The upper part of the reinforcement piles used a grid area with a diameter of 1.7m and the lower part used a full-span reinforcement area with a diameter of 2.4m. The pile spacing was 1.7m and the interlocking of the lower full-span area was 70cm. The allowable deviation of the interlocking of the three piles in the quincunx pattern was only 21cm. This formed a full-section interlocking pile at the bottom of the foundation pit, thereby achieving the water sealing effect of the reinforcement surface.

[0087] To achieve the desired reinforcement effect, the verticality deviation of the reinforced piles must not exceed 1 / 400, meaning that for a 54m deep reinforcement, only a tilt deviation of 13.5cm is allowed. During planar layout, the deviation must be ≤5cm, requiring high precision. Under both conditions, the theoretical deviation reaches 18.5cm, leaving only a 2.5cm tolerance for safe bottom sealing. From the perspective of the entire reinforcement construction, further improving the verticality deviation is challenging. Therefore, the main approach is to address the deviation in planar layout to improve the safety bottom sealing tolerance. Meanwhile, conventional RTK layout uses a 12m high handheld layout pole for positioning. Due to the pole's length and the stability limitations of manual handling, while the layout progress meets the ≤5cm planar layout deviation requirement, the accuracy is insufficient.

[0088] In this regard, this application also provides a method for using any of the above-described stakeout devices, wherein, during the construction of an ultra-deep foundation reinforcement structure for a bridge, the method includes:

[0089] S1: Insert the casing 10, lay out the coordinates of the pilot hole pile, and then use a rotary drill to drill the pilot hole.

[0090] S2: The layout component is fixed on the adjustment assembly 30 via the layout platform 61. The base 20 is firmly fixed to the protective casing 10 by tightening the four mounting components 40 and rotating the mounting rod 42. Furthermore, to speed up the layout, the X and Y axes can be aligned with due east and due north when installing the entire layout device; the height of the three legs on the centering base 20 is adjusted to level the instrument, thereby achieving vertical downward control of the Z-axis of the precise control device, making the layout head vertically downward.

[0091] S3: The position of the layout component at the construction opening 21 is adjusted by the adjustment assembly 30. Specifically, based on the coordinates to be laid out for this reinforced pile, a professional surveyor, according to the measurement of the layout machine head, slowly rotates the first screw 322 of the first adjustment component 11 to adjust the layout center to be coaxial with the Y-axis. Depending on the accuracy of the layout equipment, the deviation can reach ±1mm. Based on the coordinates to be laid out for this reinforced pile, the professional surveyor, according to the measurement of the layout machine head and the prompts from the layout handpiece, slowly rotates the second screw 332 of the second adjustment component 12 to adjust the layout center to be coaxial with the X-axis. Depending on the accuracy of the layout equipment, the deviation can reach ±1mm. This ensures accurate acquisition of the layout points.

[0092] S4. After the layout is completed, remove the layout platform 61 and other layout mechanisms on the base 20, such as the layout seat and layout head, and make partial adjustments or resets to make the construction port 21, the first adjustment hole and the second adjustment hole coaxial.

[0093] S5: Lay the roadbed box, use a crane to lift and position the main unit, adjust the position and direction of the main unit so that the center of the bottom of the drill bit is initially aligned with the center of the pilot hole, and use the extendable outriggers to level the main unit. By precisely controlling the operating valve of the jet grouting main unit cantilever beam, adjust it forward, backward, left, and right to ensure that the jet grouting drill rod can smoothly pass through the construction opening 21, the first adjustment hole, and the second adjustment hole, thereby achieving accurate positioning. The deviation of the jet grouting drill rod in the positioning of the main unit can be controlled within ±5mm.

[0094] S6. Install the jet grouting drill rod at the construction port 21 and perform the jet grouting process. Adjust the position of the jet grouting drill rod at the construction port 21 using the adjustment component 30. Specifically, due to the swinging or vibration of the equipment, the equipment may shift. During the jet grouting reinforcement process, observe whether the jet grouting drill rod is attached to the wall of the second adjustment hole to achieve precise control of the position during the reinforcement process and realize refined management.

[0095] S7. After the jet grouting process is completed, remove the jet grouting drill rod and main unit and other construction equipment.

[0096] S8. Use the aforementioned layout device to construct the foundation reinforcement structure. For example, use the device as a safety protection device for the initial setting of the reinforcement cement slurry and the orifice, thus achieving multiple uses for one device.

[0097] The layout device provided in this application strictly controls the deviation to achieve the interlocking of the reinforced piles. By strictly controlling the planar deviation of the pile position, the safety factor of the allowable verticality deviation is improved, thereby reducing the construction difficulty on the one hand and improving the reinforcement quality on the other, forming a full-section water-sealing structure. When used with the RTK precision layout instrument, the planar position deviation can be controlled at the mm level, achieving precise layout of the planar position of the reinforced piles.

[0098] With a total of 2,500 reinforcement piles, a large number of piles are being constructed daily, resulting in a large workload for pile location layout. Using this method for layout can improve the speed of layout, reducing the number of layouts from 3 to 2. At the same time, it can extend the layout time and cycle, increase the time flexibility of layout, and reduce the workload.

[0099] Furthermore, during the jet grouting process, quantifying the process control data of the ultra-high pressure jet grouting equipment allows for real-time determination of whether the reinforced pile plane exceeds limits. This prevents equipment vibration or slippage due to weak foundations from causing inaccurate positioning during layout and errors during reinforcement. This device allows for precise positioning of the drill rod with a small gap on each side. By observing whether the drill rod is in contact with the second adjustment hole during reinforcement, it's possible to determine if the planar position has shifted, thus providing control.

[0100] During the construction of foundation reinforcement structures, the construction safety is high. This device can also play a role in protecting the borehole opening. The diameter of the pilot hole is 65cm and the depth is 54m. During the 24 hours from the completion of the pilot hole to the completion of the reinforcement and hardening, it plays a role in protecting the borehole opening and preventing personnel from falling into the reinforcement hole.
