Description

TECHNICAL FIELD

[0001] The present application relates to the ship launching rail construction technical field, in particular to a kind of construction control method of multiple rows parallel rail. BACKGROUND

[0002] In the shipbuilding field, as a key link, the traditional method usually adopts double-row parallel rail to form relatively independent inclined ship frame structure. The core of track installation is the pre-embedded precision of steel pad, and the conventional practice uses steel pad with a standard length of 3 meters, which is fixed by secondary pouring process. The specific construction process is as follows: first, use total station and other measuring equipment to preliminarily position the steel pad, then temporarily weld it to the reinforcement cage of the base beam; then pour the lower concrete layer and wait for hardening; after the concrete solidifies, install the pre-bolt in the reserved hole, and adjust the steel pad to the theoretical elevation on the primary pouring surface with the help of adjusting screw; then secondary pouring is carried out, and the steel pad is fixed by using pre-bolt nut; finally, the track and pressing plate are assembled on the surface of the steel pad. However, the reinforcement cage is prone to deformation during construction, which leads to positioning deviation of the steel pad, and further causes insufficient installation precision of the track. SUMMARY

[0003] The problem solved by the present application is: how to improve the construction precision of multiple rows parallel rail.

[0004] To solve the above problems, the present application provides a construction control method for multiple rows parallel rail, comprising the following steps: A support is placed between the steel pad and the base cushion beam, the top of the support is connected with the steel pad, and the bottom of the support is connected with the base cushion beam; A plurality of pre-bolts are arranged along the extension direction of the track, the threaded portion of each pre-bolt penetrates the steel pad and the top of the support, and two adjusting nuts are assembled on the threaded portion, the two adjusting nuts clamping the steel pad and the top of the support; Pour concrete between the steel pad and the base cushion beam, and after the concrete solidifies, assemble the track on the steel pad.

[0005] Optionally, the construction control method for multiple rows parallel rail further comprises the following steps: Before assembling the track, a three-dimensional spatial model of multiple rows parallel rail is established; A monitoring point is set on the axis of each track model at a first distance, and the monitoring points at the same position of multiple track models form contour lines, and multiple contour lines are perpendicular to multiple axes; When assembling the tracks, each track replicates the monitoring point, and any contour line formed by connecting the monitoring points at the same location on multiple tracks is perpendicular to the axis of the track.

[0006] Optionally, the construction control method for multiple rows of parallel tracks further includes the following steps: The reinforcing cage is placed between the steel pad and the foundation beam, and the reinforcing cage is connected to the support.

[0007] Optionally, the rail assembly on the steel pad includes: Two rows of track fixing seats are provided on each of the steel pads, the track is located between the two rows of track fixing seats, and one end of each track fixing seat is welded to the steel pad, while the other end presses down on the track.

[0008] Optionally, the rail assembly on the steel pad further includes: A rubber pad is provided between the track and the steel pad.

[0009] Optionally, the bracket includes a top plate, a bottom plate, and a support column connecting the top plate and the bottom plate. The support column is inserted and fixed to the foundation pad beam. The threaded portion passes through the top plate and the steel pad, and the top plate and the steel pad are located between the two adjusting nuts.

[0010] Optionally, the construction control method for multiple rows of parallel tracks further includes the following steps: Displacement sensors are installed at both ends of the steel pad along its length, and an inclination sensor is installed in the middle of the steel pad. During the concrete pouring process, the displacement and tilt data of the steel pad are monitored in real time by the displacement sensors and the inclination sensor. If the data exceeds the threshold, the adjustment nut is rotated to correct the displacement and tilt angle of the steel pad.

[0011] Optionally, the concrete is early-strength, high-flowability concrete, which is poured between the steel pad and the foundation pad beam through layered pouring and low-vibration compaction.

[0012] Optionally, the bracket is made of high-strength alloy steel and coated with a marine-grade anti-corrosion coating.

[0013] Optionally, the steel pad is 6 meters long and is manufactured by plasma or laser CNC automatic cutting.

[0014] Compared with existing technologies, the construction control method for multi-row parallel tracks of the present invention, by placing a bracket between the steel pad and the foundation beam, with the top of the bracket connected to the steel pad and the bottom of the bracket connected to the foundation beam, forms a rigid support structure between the steel pad and the foundation beam. This effectively isolates the influence of deformation of the foundation beam or reinforcing cage on the positioning of the steel pad, ensuring that the steel pad remains stable at the adjusted elevation. That is, during the concrete pouring process, the position of the steel pad is no longer affected by changes in the foundation structure, thereby improving the installation accuracy of the steel pad. Furthermore, by arranging multiple pre-embedded bolts at intervals along the track extension direction, each pre-embedded bolt...

Then, by pouring concrete between the steel pad and the foundation beam, and after the concrete has solidified, the track is assembled on the steel pad. The solidified concrete can be used to lock the construction position of the steel pad. Moreover, the secondary pouring step in the traditional method is eliminated, and the track can be directly assembled on the steel pad, which simplifies the construction process and improves construction efficiency.

[0019] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in sequences other than those illustrated or described herein.

[0020] Combination Figures 1 to 3 As shown, this embodiment of the invention provides a construction control method for multiple rows of parallel tracks, comprising the following steps: Step 1: Place bracket 4 between steel pad 1 and foundation beam 5. The top of bracket 4 is connected to steel pad 1, and the bottom of bracket 4 is connected to foundation beam 5. Step 2: Arrange multiple pre-embedded bolts 2 at intervals along the extension direction of the track. The threaded part of each pre-embedded bolt 2 passes through the top of the steel pad 1 and the bracket 4, and two adjusting nuts 3 are installed on the threaded part. The two adjusting nuts 3 clamp the top of the steel pad 1 and the bracket 4. Step 3: Pour concrete between the steel pad 1 and the foundation beam 5, and after the concrete has solidified, assemble the track on the steel pad 1.

[0021] Specifically, the bracket 4 can achieve its function in various ways, such as by adopting a detachable modular design, an integrated molding structure, or a combined assembly structure. Its material can be metal, composite materials, or other materials with sufficient strength. Furthermore, the bracket 4 can be installed using methods such as plug-in connection, snap-fit ​​connection, or bolt fixing to adapt to different construction needs. A single track is installed on the corresponding steel pad 1, with the track extending in the same direction as the length of the steel pad 1. Before construction, multiple positioning holes are pre-drilled on the steel pad 1, equidistantly arranged along its length (the direction of track extension), with each positioning hole corresponding to a pre-embedded bolt 2.

[0022] During the construction of the steel pad 1, each pre-embedded bolt 2 is equipped with two adjusting nuts 3. After the bracket 4 is placed between the steel pad 1 and the foundation pad beam 5, one adjusting nut 3 can be installed on the pre-embedded bolt 2 first. Then, the threaded part of the pre-embedded bolt 2 passes through the top of the bracket 4 and the positioning hole on the steel pad 1 from bottom to top, and extends out from the positioning hole on the steel pad 1. Then, another adjusting nut 3 is installed on the pre-embedded bolt 2. The two adjusting nuts 3 clamp the top of the bracket 4 and the steel pad 1. Then, the bottom of the bracket 4 is inserted and fixed to the foundation pad beam 5. The bracket 4 forms a support structure between the steel pad 1 and the foundation pad beam 5. Because the steel pad 1 is relatively long, some parts of it may bend upwards or downwards due to assembly. In this case, it can be leveled using adjusting nuts 3. For example, if a certain position on the steel pad 1 bulges upwards, it indicates that the adjusting nut 3 below or near that bulging position is overtightened. The adjusting nut 3 at that position needs to be loosened, and then the corresponding adjusting nut 3 above it should be tightened. The threaded connection between the adjusting nut 3 and the pre-embedded bolt 2 will press down the bulging position. It should be noted that in this embodiment, leveling the steel pad 1 means ensuring that the steel pad 1 is parallel to the foundation beam 5, that is, the plane of the steel pad 1 is on the construction slope. Then, concrete is poured between the steel pad 1 and the foundation beam. During the concrete pouring process, the support 4 can overcome the displacement of the steel pad 1 caused by the pouring, thus requiring only one pour. After the concrete solidifies, the track can be directly assembled on the steel pad 1.

[0023] Thus, by placing a bracket 4 between the steel pad 1 and the foundation beam 5, with the top of the bracket 4 connected to the steel pad 1 and the bottom of the bracket 4 connected to the foundation beam 5, the bracket 4 can form a rigid support structure between the steel pad 1 and the foundation beam. This effectively isolates the influence of deformation of the foundation beam or reinforcing cage on the positioning of the steel pad 1, ensuring that the steel pad 1 remains stable at the adjusted elevation. That is, during the concrete pouring process, the position of the steel pad 1 is no longer affected by changes in the foundation structure, thereby improving the installation accuracy of the steel pad 1. By arranging multiple pre-embedded bolts 2 at intervals along the track extension direction, the threaded part of each pre-embedded bolt 2 penetrates the steel pad 1 and the bracket. The top of the steel pad 1 and the support 4 are fitted with two adjusting nuts 3 on the threaded part. The two adjusting nuts 3 clamp the top of the steel pad 1 and the support 4. The adjusting nuts 3 can ensure the stability of the connection between the top of the steel pad 1 and the support 4. On the other hand, the steel pad 1 can be leveled by rotating the adjusting nuts 3. Then, by pouring concrete between the steel pad 1 and the foundation pad beam 5, and after the concrete has solidified, the track is assembled on the steel pad 1. The solidified concrete can be used to lock the construction position of the steel pad 1. In addition, the secondary pouring step in the traditional method is eliminated, and the track can be directly assembled on the steel pad 1, which simplifies the construction process and improves the construction efficiency.

[0024] Optionally, combinedFigure 4 As shown, the construction control method for multiple parallel tracks also includes the following steps: Step 4: Before assembling the tracks, create a three-dimensional spatial model of multiple rows of parallel tracks; Step 5: Set a monitoring point b at a first distance on axis a of each track model. Connect the monitoring points b at the same location of multiple track models to form contour lines c. All contour lines c are perpendicular to multiple axes a. Step 6: When assembling the tracks, each track replicates monitoring point b, and any contour line c formed by connecting monitoring points b at the same location on multiple tracks is perpendicular to the track axis a.

[0025] Specifically, a 1:1 three-dimensional spatial model of multiple rows of parallel tracks is established based on the track construction slope. In this model, the track axis 'a' is considered the corresponding track, with n tracks set along the parallel direction. On each axis 'a', a monitoring point 'b' is set every 5 meters. The lines connecting multiple monitoring points 'b' at the same location form contour lines 'c'. The multiple track axes 'a' and contour lines 'c' form a contour line measurement control network, with each contour line 'c' perpendicular to the multiple axes 'a'. During actual track assembly, referring to the monitoring points 'b' on axis 'a' in the track model, multiple monitoring points 'b' are replicated on the track, ensuring that any contour line 'c' formed by connecting monitoring points 'b' at the same location on multiple tracks is perpendicular to the track axis 'a', and that multiple monitoring points 'b' are all located on the same contour line 'c'.

[0026] Based on the principle of consistent height of contour line c, the elevation relationship of multiple rows of tracks is intuitively reflected. The coordinates of the control points on contour line c are strictly adjusted to the correct position, and the dimensions are verified with measuring tools such as steel tape measures. This makes small deviations in the height direction visible, which facilitates quick location and correction of elevation inconsistencies.

[0027] Thus, by establishing a three-dimensional spatial model of multiple parallel tracks before assembling the tracks, and setting a monitoring point b at a first interval on the axis a of each track model, the contour lines c are formed by connecting the monitoring points b at the same position on multiple track models. The contour lines c are all perpendicular to the multiple axes a, which can simulate the actual track construction position. Then, by replicating the monitoring points b on each track during assembly, and ensuring that any contour line c formed by connecting the monitoring points b at the same position on multiple tracks is perpendicular to the track axis a, the installation position of each track can be corrected using the contour lines c. This ensures that each track is assembled on the steel pad 1 strictly according to the position of the three-dimensional spatial model of multiple parallel tracks, thereby improving the installation accuracy of the tracks.

[0028] Optionally, the construction control method for multiple rows of parallel tracks also includes the following steps: Place the steel cage between the steel pad 1 and the foundation pad beam 5, and connect the steel cage to the support 4.

[0029] Specifically, a reinforcing cage refers to a cage-like structure made of reinforcing bars, which can be formed by binding or welding multiple longitudinal reinforcing bars and transverse stirrups. In step two, the reinforcing cage is precisely placed between the steel base plate 1 and the foundation beam 5. The reinforcing cage serves as a reinforcing structure during concrete pouring. By connecting the reinforcing cage to the support 4, a composite load-bearing system is formed. This system not only enhances the overall structural stability but also effectively reduces the risk of foundation deformation caused by external loads or environmental factors. With the assistance of the reinforcing cage, the support 4 maintains a precise position during concrete pouring, avoiding displacement problems caused by vibration or gravity, thereby ensuring the geometric accuracy of the track installation and the stability of long-term operation.

[0030] Thus, by placing the steel cage between the steel pad 1 and the foundation pad beam 5 during step two, and connecting the steel cage to the support 4, the steel cage and the support 4 work together to enhance the stability of the steel pad 1 during the pouring process.

[0031] Optionally, the rail assembly on the steel base plate 1 includes: Two rows of track fixing seats 6 are set on each steel pad 1, with the track located between the two rows of track fixing seats 6, and one end of each track fixing seat 6 is welded to the steel pad 1, while the other end presses down on the track.

[0032] Specifically, the track fixing seat 6 is a rigid structural component used to fix the track and apply downward pressure. Two rows of track fixing seats 6 are installed on each steel base plate 1, with the track located between the two rows of track fixing seats 6. One end of the track fixing seat 6 is permanently connected to the steel base plate 1 by welding to ensure stability during subsequent use. The other end of the track fixing seat 6 is designed to apply vertical downward pressure to the track to prevent displacement by directly constraining the track's degrees of freedom.

[0033] In this way, a rigid connection system is constructed by welding one end of the track fixing seat 6 to the steel pad 1. The other end of the track fixing seat 6 applies continuous downward pressure to the track, and the track is located between the two rows of track fixing seats 6. The two rows of track fixing seats 6 restrict the possibility of track movement in the horizontal and vertical directions, which not only simplifies the track installation process and reduces the need for repeated adjustments, but also significantly improves the integrity and stability of the track and the foundation structure.

[0034] Optionally, the rail assembly on the steel base plate 1 includes: Two rows of track fixing seats 6 are set on each steel pad 1, with the track located between the two rows of track fixing seats 6, and one end of each track fixing seat 6 is welded to the steel pad 1, while the other end presses down on the track.

[0035] Specifically, when the track is subjected to operating loads, the rubber pad undergoes controllable elastic deformation, consuming impact energy and thus significantly suppressing minor deviations in track position, ensuring long-term stability of installation accuracy. Simultaneously, the rubber pad can adapt to minor uneven settlement or deformation of the foundation, avoiding stress concentration caused by rigid connections and reducing mechanical wear between the track and the steel pad 1.

[0036] Thus, by setting a rubber pad between the track and the steel pad 1, the rubber pad can cooperate with the downward pressure of the track fixing seat 6, enhancing the overall stability of the track. This not only improves the track installation accuracy but also significantly improves the vibration resistance and service life of the track system.

[0037] Optionally, combined Figure 3 As shown, the bracket 4 includes a top plate 41, a bottom plate 42, and a support column 43 connecting the top plate 41 and the bottom plate 42. The support column 43 is inserted and fixed to the foundation pad beam 5. The threaded part passes through the top plate 41 and the steel pad 1. The top plate 41 and the steel pad 1 are located between two adjusting nuts 3.

[0038] Specifically, the top plate 41 and the bottom plate 42 are parallel to the steel pad 1. There are two rows of support columns 43. The top plate 41 and the bottom plate 42 are located between the two rows of support columns 43 and are connected to the two rows of support columns 43. The top plate 41, the bottom plate 42 and the support columns 43 form a frame structure. Before pouring, the bottom of the support column 43 is inserted and fixed on the foundation pad beam, and the threaded part of the pre-embedded bolt 2 passes through the top plate 41 and the steel pad 1. The top plate 41 and the steel pad 1 are located between two adjusting nuts 3.

[0039] Thus, by inserting and fixing the support column 43 to the foundation pad beam 5, and by connecting the top plate 41 and the bottom plate 42, the support column 43 ensures the stability of the top plate 41 and the bottom plate 42, so that the top plate 41, the bottom plate 42 and the support column 43 can form a stable frame support structure during the concrete pouring process, thereby ensuring the stability of the steel pad 1 during the concrete pouring process.

[0040] Optionally, the construction control method for multiple rows of parallel tracks also includes the following steps: Displacement sensors are installed at both ends of the steel pad 1 along its length, and an inclination sensor is installed in the middle of the steel pad 1. During the concrete pouring process, the displacement and tilt data of the steel pad 1 are monitored in real time by the displacement sensors and the inclination sensor. If the data exceeds the threshold, the adjustment nut 3 is rotated to correct the displacement and tilt angle of the steel pad 1.

[0041] Specifically, the length direction of the steel pad 1 is the same as the track extension direction. Displacement sensors are used to detect changes in the horizontal position of the steel pad 1; these can be laser displacement sensors, inductive displacement sensors, or ultrasonic displacement sensors. Tilt sensors are used to measure the tilt angle of the steel pad 1 in the vertical direction; these can be MEMS tilt sensors, electrolyte tilt sensors, or fiber optic tilt sensors. By installing displacement sensors at both ends of the steel pad 1 along its length, and considering that the displacement of the steel pad 1 in the length dimension often exhibits synchronous offset at both ends, capturing the relative positional changes at both ends allows for accurate identification of overall translational or extensive deformation. Tilt sensors are installed in the middle of the steel pad 1. Since the middle region of the steel pad 1 is most sensitive to bending or tilting deformation, tilt monitoring at this location can effectively reflect the tilting state of the steel pad 1 caused by uneven foundation stress or vibration.

[0042] If the steel pad 1 shifts during concrete pouring, it may be due to the adjusting nut 3 becoming loose. Tightening the adjusting nut 3 will correct the shift. Similarly, if the steel pad 1 bends or deforms in the middle, the adjusting nut 3 can be adjusted to correct its tilt angle. This ensures that minor deviations during construction are detected before they accumulate into significant errors, avoiding the lag in post-construction inspections. When monitoring data triggers a threshold, the displacement and tilt angle of the steel pad 1 can be corrected by adjusting the adjusting nut 3.

[0043] Thus, by installing displacement sensors at both ends of the steel pad 1 along its length and tilt sensors at the middle of the steel pad 1, the displacement and tilt data of the steel pad 1 can be monitored in real time during the concrete pouring process. If the data exceeds the threshold, the adjustment nut 3 is rotated to correct the displacement and tilt angle of the steel pad 1. This enables the concrete pouring process to have real-time feedback and instant adjustment capabilities, which not only improves the positional stability of the steel pad 1 during the concrete pouring process but also significantly improves the accuracy and smoothness of the track installation, thus ensuring the overall operational reliability of the multi-row parallel track system.

[0044] Optionally, the concrete is early-strength, high-flowability concrete, which is poured between the steel pad 1 and the foundation pad beam through layered pouring and low-vibration compaction.

[0045] Specifically, early-strength high-flowability concrete refers to special concrete with rapid hardening and excellent flowability, which can be made from cement-based materials incorporating high-efficiency water-reducing agents and early-strength agents. Layered pouring is a method of gradually pouring concrete in batches to avoid concentrated impact loads caused by excessive single pours, thereby ensuring the stability of the pouring process. Low-vibration compaction refers to an operation method that controls the vibration intensity to the minimum necessary level while ensuring the density of the concrete, aiming to reduce the disturbance of the vibration equipment to the steel pad 1.

[0046] Thus, early-strength, high-flowability concrete was chosen. Its early-strength characteristics accelerated the hardening process, shortened the transition time from pouring to structural stability, and reduced the possibility of the steel plate 1 tilting due to external forces during the solidification stage. Furthermore, the early-strength, high-flowability concrete was poured in layers and compacted with low vibration between the steel plate 1 and the foundation beam. The high flowability of the early-strength, high-flowability concrete allowed it to flow smoothly and fully fill the voids, reducing the need for high-intensity vibration. This avoided the risk of displacement caused by vibration energy being transferred to the steel plate 1 during vibration. The layered pouring method ensured that the pouring pressure was evenly distributed between the steel plate 1 and the foundation beam, further suppressing local deformation. Low-vibration compaction ensured the concrete's density while minimizing disturbance to the steel plate 1, guaranteeing the accuracy of the displacement and tilt sensor data and preventing frequent compensation adjustments due to false alarms.

[0047] Optionally, the bracket 4 is made of high-strength alloy steel and coated with a marine-grade anti-corrosion coating.

[0048] Specifically, high-strength alloy steel can be steel with added alloying elements such as chromium and nickel. Marine-grade anti-corrosion coatings can be achieved through methods such as spraying epoxy resin coatings or polyurethane coatings. In the construction control method for multiple parallel tracks, the support frame 4, as a key supporting component, has its top plate 41, bottom plate 42, and support column 43 all made of high-strength alloy steel. This ensures that the support frame 4 can effectively suppress bending and torsion when subjected to construction loads and environmental stresses, thereby maintaining the long-term stability of the steel pad 1. Simultaneously, the marine-grade anti-corrosion coating applied to the surface of the support frame 4 forms a dense protective layer, suitable for the actual operating environment of ship launching systems, overcoming the problem of rapid failure of conventional coatings under marine conditions.

[0049] Thus, by using high-strength alloy steel to make bracket 4 and coating its surface with marine-grade anti-corrosion coating, bracket 4 can not only maintain structural integrity under complex working conditions, but also significantly extend its service life and reduce maintenance intervention, providing a reliable foundation for the high-precision installation of the track system. In this way, the use of bracket 4 in conjunction with components such as pre-embedded bolts 2 and adjusting nuts 3 further enhances the accuracy and stability of adjusting the position of steel pad 1 during construction, thereby improving the overall construction efficiency and quality.

[0050] Optionally, the steel pad 1 is 6 meters long and is manufactured by plasma or laser CNC automatic cutting.

[0051] Specifically, plasma or laser CNC automatic cutting uses computer-controlled cutting equipment to precisely cut metal materials, which can meet the processing requirements of complex shapes and high-precision dimensions. Its purpose is to ensure the edge flatness and dimensional consistency of the steel pad 1.

[0052] Thus, in traditional construction methods, the 3-meter-long steel base plate 1 is easily affected by the deformation of the reinforcing cage due to the large number of splices, leading to a decrease in positioning accuracy. However, increasing the length of the steel base plate 1 to 6 meters significantly reduces the number of splices in the track extension direction, thereby reducing the risk of displacement caused by stress concentration or deformation at the splices. At the same time, the application of plasma or laser CNC automatic cutting technology greatly improves the manufacturing precision of the steel base plate 1, avoiding the dimensional deviation problems common in traditional manual or semi-automatic cutting. This not only simplifies the on-site installation steps but also reduces the time for secondary adjustments due to manufacturing errors, thereby effectively improving construction efficiency and the overall assembly quality of the track system.

[0053] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
