Description

Technical Field

[0001] The present application relates to the technical field of bridge construction, and in particular to a suspension bridge anchor pipe positioning device and positioning method. Background Art

[0002] The force of suspension bridge cables is mainly borne by the anchoring structure. The anchor pipe is one of the main anchoring forms of suspension bridges and is also the key force-bearing structure of suspension bridges. Anchor pipe installation generally adopts layered installation and layered pouring of anchor concrete. Positioning measurement is repeated and very complicated. The positioning measurement of anchor pipes requires high accuracy, the spatial geometric relationship between anchor pipes requires precision, and the measurement environment is complex, which is a challenge for on-site measurement work.

[0003] In the related art, the total station coordinate method is generally used for anchor pipe positioning measurement. The total station is placed on the control point of the bridge control network, and each anchor pipe on each layer is absolutely positioned one by one. The positioning workload is large, and there are defects such as a large number of measurement personnel and low measurement and installation efficiency. In the related art, there is also a method for positioning and measuring anchor pipe groups using the "universal rangefinder + tube head prism" tooling, but more than three adjusted anchor pipes in different layers are required as control points to adjust the anchor pipe to be positioned. The number of control points required is large and the calculation is difficult. At the same time, the "universal rangefinder + tube head prism" tooling is complex and has low operating efficiency. It is suitable for the positioning construction of large-scale anchor pipe groups, but it is not suitable for the general suspension bridge anchor pipe positioning construction that uses layer-by-layer positioning of anchor pipes. There are defects such as a large number of control points required, complex process, and low efficiency, which urgently need to be improved. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] The embodiments of the present application provide a suspension bridge anchor pipe positioning device and positioning method, which can solve the technical problems existing in the prior art of using a conventional layer-by-layer anchor pipe positioning method, which requires a large number of control points, has a complex process and is inefficient.

[0030] In a first aspect, an embodiment of the present application provides a suspension bridge anchor pipe positioning device.

[0031] Reference Figure 1 , Figure 1 Schematic diagram of the anchor pipe positioning device for a suspension bridge according to an embodiment of the present application. Figure 1 As shown, in one embodiment, the anchor pipe positioning device of the suspension bridge includes a first telescopic measuring rod 1 and a second telescopic measuring rod 2, and the two ends of the first telescopic measuring rod 1 are respectively vertically and detachably mounted on two adjusted anchor pipes 4 through fasteners 3. One end of the second telescopic measuring rod 2 is vertically and detachably mounted on the anchor pipe 5 to be adjusted through fasteners 3, and the other end is slidably arranged on the pipe body of the first telescopic measuring rod 1, and the second telescopic measuring rod 2 and the first telescopic measuring rod 1 are perpendicular to each other.

[0032] In this embodiment, the first telescopic measuring rod 1 and the second telescopic measuring rod 2 are both telescopic measuring rods, which are telescopically extended section by section, and the joints of two adjacent sections can be fixed by fastening screws 32. In addition, the plane where the first telescopic measuring rod 1 and the second telescopic measuring rod 2 are located is parallel to the bottom surface of the anchor. The fastener 3 can be a clamp or a clamp.

[0033] In this embodiment, the two ends of the first telescopic measuring rod 1 are vertically installed on two adjusted anchor pipes 4 by fasteners 3 respectively, which is not only suitable for the positioning construction of anchor pipes of suspension bridges of different specifications, but also can form a stable positioning reference; one end of the second telescopic measuring rod 2 is vertically installed on the anchor pipe 5 to be adjusted by fasteners 3, and the other end is slidably set on the tube body of the first telescopic measuring rod 1, and the second telescopic measuring rod 2 and the first telescopic measuring rod 1 are perpendicular to each other, so that not only the second telescopic measuring rod 2 can be allowed to move and adjust to a certain extent on the first telescopic measuring rod 1, but also this sliding connection facilitates the adjustment of the relative position between the second telescopic measuring rod 2 and the first telescopic measuring rod 1, and by reading the scale at the intersection of the first telescopic measuring rod 1 and the second telescopic measuring rod 2, and the length of the second telescopic measuring rod 2, the scale corresponding to the actual vertical foot of the anchor pipe 5 to be adjusted projected on the first telescopic measuring rod 1, and the actual vertical distance from the anchor pipe 5 to be adjusted to the first telescopic measuring rod 1 can be determined, thereby achieving accurate positioning of the anchor pipe 5 to be adjusted.

[0034] In addition, the first telescopic measuring rod 1 and the second telescopic measuring rod 2 can be detachably installed on the anchor pipe (including the adjusted anchor pipe 4 and the anchor pipe 5 to be adjusted), which makes it easier for operators to install and remove the first telescopic measuring rod 1 and the second telescopic measuring rod 2 more quickly, bringing convenience to the anchor pipe positioning construction of the suspension bridge. Through the above technical solution, only two control points (i.e., two adjusted anchor pipes 4) are required to achieve accurate positioning of the anchor pipe 5 to be adjusted, with a simple process and high efficiency, solving the technical problems existing in the prior art of using conventional layer-by-layer anchor pipe positioning methods, requiring a large number of control points, complex processes and low efficiency.

[0035] Further, in one embodiment, if Figure 1 As shown, the axis of the first telescopic measuring rod 1 and the axis of the adjusted anchor pipe 4 are located in the same plane, and the axis of the second telescopic measuring rod 2 and the axis of the anchor pipe 5 to be adjusted are located in the same plane. In this embodiment, through the above technical solution, it can be ensured that no error caused by angle deviation will occur during the measurement process. In fact, by measuring in this way, construction personnel can observe and measure more easily without complicated angle adjustment or calculation, which simplifies the construction process and improves work efficiency.

[0036] Further, in one embodiment, if Figure 1 As shown, the first telescopic measuring rod 1 includes a first sleeve 11 with a scale, and a round rod 12 with a scale coaxially and telescopically arranged at both ends of the first sleeve 11, and a fastener 3 is provided at the protruding end of the round rod 12. In this embodiment, through the above technical solution, the first sleeve 11 and the round rod 12 are both provided with scales, which makes the measurement process more intuitive and accurate. The round rod 12 is coaxially and telescopically arranged at both ends of the first sleeve 11, so that the first telescopic measuring rod 1 can be adjusted as needed and can adapt to different measurement requirements. The protruding end of the round rod 12 is provided with a fastener 3, which can be arranged in an integrated welding manner or by screwing in and installing.

[0037] In addition, the sleeve and the round rod 12 are made of high-strength materials and have high hardness and durability, so that the first telescopic measuring rod 1 can maintain stable performance even under harsh environmental conditions and extend its service life.

[0038] Further, in one embodiment, if Figure 1 As shown, the second telescopic measuring rod 2 includes a circular tube 21 with scale, a second sleeve 22 with scale and a round rod 12 with scale, the circular tube 21 is slidably sleeved on the first sleeve 11, one end of the second sleeve 22 is centrally arranged on the tube body of the circular tube 21, the round rod 12 is coaxially and telescopically arranged on the other end of the second sleeve 22, and the protruding end of the round rod 12 is provided with a fastener 3. In this embodiment, through the above technical scheme, it is ensured that the second telescopic measuring rod 2 is moved and adjusted to a certain extent on the first telescopic measuring rod 1. In addition, the second sleeve 22 and the round rod 12 are both provided with scales, which makes the measurement process more intuitive and accurate; the round rod 12 is coaxially and telescopically arranged at both ends of the second sleeve 22, so that the second telescopic measuring rod 2 can be adjusted as needed and can adapt to different measurement requirements. The protruding end of the round rod 12 is provided with a fastener 3, which can be arranged in an integrally welded manner or by screwing in and installing.

[0039] Further, in one embodiment, if Figure 1As shown, the round bar 12 and the first sleeve 11, and the round bar 12 and the second sleeve 22 are all fixed by fixing screws. In the present embodiment, through the above technical solution, the fixing screw can provide a firm connection, so that the round bar 12 and the sleeve (including the first sleeve 11 and the second sleeve 22) are not easy to move or loosen relative to each other, and the overall structural stability of the first telescopic measuring rod 1 or the second telescopic measuring rod 2 is enhanced, so that it can maintain high accuracy and reliability during use. In addition, through the fixing screw, it is convenient for the construction personnel to adjust the extension length of the round bar 12 in the sleeve to meet different measurement requirements. After the adjustment is completed, the position of the round bar 12 can be fixed by tightening the fixing screw, which can prevent it from sliding during use. At the same time, because the fixing screw provides a stable connection, the relative position between the round bar 12 and the sleeve remains unchanged. This helps to ensure the accuracy during the measurement process and avoids the error caused by loose connection.

[0040] Further, in one embodiment, if Figure 1 As shown, the fastener 3 includes a U-shaped clamp 31 and a plurality of fastening screws 32. The U-shaped clamp 31 is connected to the protruding end of the round rod 12. The plurality of fastening screws 32 symmetrically pass through the two arms of the U-shaped clamp 31 to clamp the adjusted anchor pipe 4 or the anchor pipe 5 to be adjusted. In this embodiment, through the above technical solution, the U-shaped clamp 31 is first tightly fitted on the adjusted anchor pipe 4 or the anchor pipe 5 to be adjusted, and then the fastening screws 32 are used for strong clamping, thereby achieving a stable connection with the anchor pipe (including the adjusted anchor pipe 4 and the anchor pipe 5 to be adjusted), effectively improving the stability and reliability of the overall structure, and ensuring that high-precision positioning can be maintained in a complex construction environment. In addition, this structure can flexibly adapt to anchor pipes of different diameters, and can meet a variety of construction needs without replacing fasteners 3 of different specifications.

[0041] Furthermore, in one embodiment, the fastening screw 32 has a scale. In this embodiment, through the above technical solution, the construction personnel can intuitively read and adjust the rotation angle or extension length of the fastening screw 32, so as to achieve accurate adjustment and positioning between the first telescopic measuring rod 1 and the adjusted anchor pipe 4, and between the second telescopic measuring rod 2 and the anchor pipe to be adjusted 5, which helps to ensure the accuracy requirements during the construction process, reduce error accumulation, and improve the overall construction quality. At the same time, the construction personnel can tighten according to the predetermined torque or clamping force according to the scale on the fastening screw 32, ensuring that each fastening point meets the same standard, thereby improving the stability and reliability of the overall structure.

[0042] In a second aspect, an embodiment of the present application provides a positioning method for a suspension bridge anchor pipe positioning device based on any of the above embodiments.

[0043] Reference Figure 2 , Figure 2Schematic diagram of the flow of the positioning method of the anchor pipe positioning device for a suspension bridge in the embodiment of the present application. Figure 2 As shown, in one embodiment, the steps of the positioning method include:

[0044] Step S10, assembling the suspension bridge anchor pipe positioning device.

[0045] In this embodiment, the positioning method used in the technical solution needs to be implemented with the help of the suspension bridge anchor pipe positioning device. Therefore, when positioning the anchor pipe 5 to be adjusted, the suspension bridge anchor pipe positioning device needs to be assembled. Figure 1 As shown, when in use, the first telescopic measuring rod 1 and the second telescopic measuring rod 2 are perpendicular to each other, and the second telescopic measuring rod 2 is slidably arranged on the tube body of the first telescopic measuring rod 1; when not in use, the first telescopic measuring rod 1 and the second telescopic measuring rod 2 are separated separately, which is convenient for storage and transportation. In addition, the anchor pipe positioning device for the suspension bridge is based on the use of two adjusted anchor pipes 4, so the two anchor pipes need to be adjusted in advance.

[0046] Step S20, vertically install the two ends of the first telescopic measuring rod 1 on the two adjusted anchor pipes 4 through fasteners 3 respectively, and vertically install one end of the second telescopic measuring rod 2 on the anchor pipe 5 to be adjusted through fasteners 3.

[0047] In this embodiment, after the suspension bridge anchor pipe positioning device is assembled, the two ends of the first telescopic measuring rod 1 can be vertically installed on the two adjusted anchor pipes 4 through the fasteners 3, and one end of the second telescopic measuring rod 2 can be vertically installed on the anchor pipe 5 to be adjusted through the fasteners 3. During the installation process, the two ends of the first telescopic measuring rod 1 installed on the adjusted anchor pipe 4 and the one end of the second telescopic measuring rod 2 installed on the anchor pipe 5 to be adjusted can be adaptively adjusted in length, which can ensure the smooth progress of the installation process. After the two ends of the first telescopic measuring rod 1 are installed on the two adjusted anchor pipes 4, a stable reference can be formed. In addition, the second telescopic measuring rod 2 is perpendicular to the first telescopic measuring rod 1, which avoids the measurement error caused by shaking and tilting of the first telescopic measuring rod 1 and the second telescopic measuring rod 2.

[0048] Step S30 , reading the scale corresponding to the actual vertical foot of the anchor pipe 5 to be adjusted projected on the first telescopic measuring rod 1 , and the actual vertical distance from the anchor pipe 5 to be adjusted to the first telescopic measuring rod 1 .

[0049] In this embodiment, since the first telescopic measuring rod 1 and the second telescopic measuring rod 2 are perpendicular to each other, the intersection of the two perpendicularities can be used as the actual vertical foot of the anchor pipe 5 to be adjusted projected on the first telescopic measuring rod 1, and the scale of the second telescopic measuring rod 2 is used as the actual vertical distance from the anchor pipe 5 to be adjusted to the first telescopic measuring rod 1. The scale corresponding to the actual vertical foot and the actual vertical distance are read to ensure the accuracy of the positioning of the anchor pipe 5 to be adjusted.

[0050] Step S40, compare the scales corresponding to the actual perpendicular foot and the theoretical perpendicular foot to obtain the first deviation of the anchor pipe 5 to be adjusted in the axial direction of the first telescopic measuring rod 1; compare the actual vertical distance and the theoretical vertical distance to obtain the second deviation of the anchor pipe 5 to be adjusted in the axial direction of the second telescopic measuring rod 2.

[0051] In this embodiment, the construction personnel will calculate the theoretical position of the anchor pipe 5 to be adjusted relative to the two adjusted anchor pipes 4 in advance according to the construction design drawings and by using geometric relationships, and further determine the theoretical foot of the theoretical position projected on the first telescopic measuring rod 1, as well as the theoretical vertical distance from the theoretical position to the first telescopic measuring rod 1, all of which are regarded as known quantities. During the positioning construction, by comparing the scales corresponding to the actual foot of the vertical and the theoretical foot of the vertical, the first deviation of the anchor pipe 5 to be adjusted in the axial direction of the first telescopic measuring rod 1 can be obtained. By comparing the actual vertical distance and the theoretical vertical distance, the second deviation of the anchor pipe 5 to be adjusted in the axial direction of the second telescopic measuring rod 2 can be obtained. The deviation between the actual position and the theoretical position of the anchor pipe 5 to be adjusted can be accurately determined by combining the first deviation and the second deviation, and standardized adjustments can be made according to the first deviation and the second deviation.

[0052] Furthermore, in one embodiment, the positioning method also includes a step of determining an installation reference plane of the suspension bridge anchor pipe positioning device, which step includes: selecting a cross section parallel to the anchor bottom surface where all anchor pipes are located as the installation reference plane of the suspension bridge anchor pipe positioning device.

[0053] In this embodiment, by selecting a cross-section common to all anchor pipes as the installation reference plane of the suspension bridge anchor pipe positioning device, it can be ensured that the first telescopic measuring rod 1 and the second telescopic measuring rod 2 of the suspension bridge anchor pipe positioning device are on the same horizontal plane, thereby improving the accuracy and consistency of the installation.

[0054] In this embodiment, according to the need for segmented adjustment of the anchor pipe 5 to be adjusted and the need for the segmented axis of the anchor pipe 5 to be adjusted to be straight, two or even more installation reference surfaces based on the two adjusted anchor pipes 4 can be flexibly selected, or the other two adjusted anchor pipes 4 can be selected to establish the installation reference surface, and the positioning and adjustment can be performed on any axis point of the anchor pipe 5 to be adjusted, so as to solve the measurement technical problems of multi-section positioning of long anchor pipes and the lack of visibility due to the obstruction of construction facilities. For example, if the axis of the middle part of the anchor pipe 5 to be adjusted is drooped and deformed due to its own gravity, an installation reference surface can be selected to be established in the middle part of the anchor pipe, and the positioning and adjustment of the axis of the middle part of the anchor pipe 5 to be adjusted can be performed. For another example, if the two adjusted anchor pipes 4 are blocked by construction facilities at the middle part of the anchor pipe 5 to be adjusted and cannot see each other, the middle part of the anchor pipe 5 to be adjusted can be selected to see the other two adjusted anchor pipes 4, and the installation reference surface can be re-established to position and adjust the axis of the middle part of the anchor pipe 5 to be adjusted. Among them, the long anchor pipe refers to an anchor pipe with a longer length and a larger volume. For example, the length of a general long anchor pipe is between 40 meters and 100 meters.

[0055] Furthermore, in one embodiment, the steps of the positioning method further include:

[0056] If the first deviation or the second deviation does not satisfy the corresponding allowable deviation range, the position of the anchor pipe 5 to be adjusted in the axial direction of the corresponding telescopic measuring rod is adjusted until the first deviation or the second deviation satisfies the corresponding allowable deviation range. If the first deviation and the second deviation do not satisfy the corresponding allowable deviation range, the position of the anchor pipe 5 to be adjusted in the axial direction of each telescopic measuring rod is adjusted until the first deviation and the second deviation both satisfy the corresponding allowable deviation range.

[0057] In this embodiment, after calculating the first deviation and the second deviation between the actual position and the theoretical position of the anchor pipe 5 to be adjusted, it is also necessary to determine whether the first deviation satisfies its corresponding allowable deviation range, and whether the second deviation satisfies its corresponding allowable deviation range. If both the first deviation and the second deviation satisfy their respective corresponding allowable deviation ranges, it means that the deviation between the actual position and the theoretical position of the anchor pipe 5 to be adjusted is not large and can be almost ignored, so no adjustment is required; if the first deviation or the second deviation does not satisfy its corresponding allowable deviation range (for example: the allowable deviation range corresponding to the first deviation is 5 mm, and the allowable deviation range corresponding to the second deviation is 3 mm, where the actual positioning construction requirements are mainly taken into account), it means that the deviation between the actual position and the theoretical position of the anchor pipe 5 to be adjusted is large, and it is necessary to adjust the axial position of the anchor pipe 5 to be adjusted on the first telescopic measuring rod 1 or adjust the axial position of the anchor pipe 5 to be adjusted on the second telescopic measuring rod 2 until the first deviation or the second deviation satisfies its corresponding allowable deviation range; if both the first deviation and the second deviation do not satisfy their respective corresponding allowable deviation ranges, it means that the deviation between the actual position and the theoretical position of the anchor pipe 5 to be adjusted is very large, and it is necessary to adjust the axial position of the anchor pipe 5 to be adjusted on the first telescopic measuring rod 1 and adjust the axial position of the anchor pipe 5 to be adjusted on the second telescopic measuring rod 2 until the first deviation and the second deviation satisfy their respective corresponding allowable deviation ranges. Through the above technical solution, the construction difficulty can be reduced and the construction efficiency can be effectively improved.
