Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction, and in particular to a method, device, computer equipment and storage medium for constructing a patching section. Background Art

[0002] The steel tube arch ribs in steel tube concrete arch bridges are mostly constructed by cantilever assembly with inclined buckles and hangings. In order to adjust the linear shape of the steel tube arch ribs during installation, a hinge axis is set at the arch foot section (i.e., the first section of the arch rib). A certain distance is left between the ends of the upper and lower chord tubes of this section and the pre-embedded steel pipes of the arch seat. After the arch ribs are installed to the designed position, the upper and lower chord tubes are connected to the pre-embedded steel pipes of the arch seat with embedded sections, completing the hinge sealing construction, a key step in the construction of steel tube arch ribs.

[0003] However, in actual construction, the pre-buried steel pipes of the arch seat are constructed according to the design, without considering the displacement of the upper and lower chord pipes of the arch foot section due to the installation of the arch ribs, resulting in a large misalignment between the ends of the upper and lower chord pipes and the ends of the pre-buried steel pipes of the arch seat, making it difficult to achieve a butt connection with a misalignment of less than 2mm allowed by the specification. At present, the designed length of the patching section can only be cut into multiple strips along the circumference direction, and forced welding is gradually performed. This not only increases the construction difficulty of the patching section and reduces construction efficiency, but also affects the overall stress and safety performance of the arch rib segment.

[0004] It can be seen that the existing method for constructing patch sections not only has the problems of great construction difficulty and low construction efficiency, but also affects the safety performance of the arch rib segments and cannot meet the construction requirements of arch bridges.

The arch seat embedded steel pipes in the present invention are embedded according to the coordinates obtained by calculating the deformation displacement of the upper chord tube and the lower chord tube of the arch foot section. The coordinates have taken into account the influence of the deformation of the upper chord tube and the lower chord tube of the arch foot section on the coordinates of the arch seat embedded steel pipes. Therefore, accurate positioning of the patching section can be achieved, ensuring that the misalignment of the patching section is within the allowable range of the specification, reducing the construction difficulty while improving the safety of the arch rib segment.

[0026] Figure 3 Shown Figure 2 A partial enlarged schematic diagram is shown in the figure. DETAILED DESCRIPTION

[0027] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] Figure 1 FIG. 1 is a flow chart of a method for constructing a patching section according to an embodiment of the present invention; FIG. Figure 1 As shown, the patching section construction method specifically includes the following steps:

[0029] Step S101 , before pre-embedding the steel pipe in the arch seat, obtain a first displacement of the upper chord pipe port of the arch foot section and a second displacement of the lower chord pipe port of the current arch foot section according to a finite element model.

[0030] In this embodiment, the steel pipes in the arch seat include the pre-embedded steel pipes on the arch seat and the pre-embedded steel pipes under the arch seat described below. Before the steel pipes in the arch seat are embedded, that is, before the pre-embedded steel pipes on the arch seat and the pre-embedded steel pipes under the arch seat are embedded, the first displacement of the upper chord tube port of the arch foot segment and the second displacement of the lower chord tube port of the current arch foot segment are obtained according to the finite element model, including: obtaining the arch rib segment installation sequence and the number of segments predetermined before the pre-embedded steel pipes in the arch seat are hinged; inputting the number of segments and the arch rib segment installation sequence into the established finite element model, and calculating the first displacement of the upper chord tube port of the current arch foot segment and the second displacement of the lower chord tube port of the current arch foot segment; wherein, the first displacement and the second displacement respectively include horizontal displacement, vertical displacement and angular displacement.

[0031] It should be noted that the steel tube concrete arch bridge is composed of several arch rib segments that are suspended and hung one by one, and each arch rib segment includes an upper chord tube and a lower chord tube, such as Figure 2 As shown in (b), the arch foot section (that is, the first section of the arch rib) 1 includes a lower chord tube 2 and an upper chord tube 3. The upper pre-buried steel pipe 5 on the arch seat corresponds to the upper chord tube 3, and the lower pre-buried steel pipe 4 under the arch seat corresponds to the lower chord tube 2. An upper patching section 7 is provided between the upper chord tube 3 and the upper pre-buried steel pipe 5 on the arch seat, and a lower patching section 6 is provided between the lower chord tube 2 and the lower pre-buried steel pipe 4 under the arch seat. In this embodiment, the hinge sealing of the pre-buried steel pipe of the arch seat includes pouring concrete for the pre-buried steel pipe of the arch seat and installing the patching section. This embodiment can be installed after the installation is completed. The hinge sealing of the embedded steel pipe of the arch seat can be carried out immediately after the arch foot section, or the hinge sealing construction can be carried out after any number of arch rib segments are installed. During the tensioning of the cables, the arch rib segments will be deformed by force, resulting in the displacement between the actual installation value and the design value of the port of the arch foot section close to the patching section. The installation sequence and the number of segments installed at different stages will affect the change of the displacement value. Therefore, the installation sequence of each segment and the segment after which the hinge sealing construction should be carried out must be determined before construction, and they will not be changed during the construction process.

[0032] Furthermore, this embodiment uses a finite element program to establish a steel tube arch construction calculation model, that is, a finite element model, for the steel tube concrete arch bridge currently under construction. As for the process of establishing the finite element model, it can be implemented by means of existing technologies and will not be described in detail here. Through the pre-established finite element model, the stress deformation of any arch rib segment during the installation process and the displacement change caused by the arch foot segment can be calculated. Therefore, the installation sequence and number of arch rib segments predetermined before the arch seat embedded steel tube is hinged are input as parameters into the finite element model, and the horizontal displacement, vertical displacement and angular displacement of the upper chord tube port of the arch foot segment, as well as the horizontal displacement, vertical displacement and angular displacement of the lower chord tube port can be obtained. Among them, the upper chord tube port includes the cantilever end center of the upper chord tube, and the lower chord tube port includes the cantilever end center of the lower chord tube, such as Figure 3 Point C in.

[0033] Step S102: Calculate the displacement values ​​of both ends of the pre-buried steel pipe on the arch seat according to the first displacement, and calculate the displacement values ​​of both ends of the pre-buried steel pipe under the arch seat according to the second displacement.

[0034] In this embodiment, the displacement values ​​of both ends of the pre-embedded steel pipe on the arch seat are calculated based on the first displacement, including: calculating the displacement value of the first end of the pre-embedded steel pipe on the arch seat based on the horizontal displacement, the vertical displacement, the angular displacement, and the length of the patching section; calculating the displacement value of the second end of the pre-embedded steel pipe on the arch seat based on the horizontal displacement, the vertical displacement, the angular displacement, the length of the patching section, and the length of the pre-embedded steel pipe on the arch seat; wherein the pre-embedded steel pipe on the arch seat is an embedded steel pipe that matches the upper chord tube of the arch foot section, the first end of the pre-embedded steel pipe on the arch seat is a port close to the upper chord tube of the arch foot section, and the second end of the pre-embedded steel pipe on the arch seat is a port away from the upper chord tube of the arch foot section; Figure 3 Point B is the first end of the embedded steel pipe on the arch seat, and point A is the second end of the embedded steel pipe on the arch seat.

[0035] The calculation formula for calculating the displacement value of the first end of the embedded steel pipe on the arch seat according to the horizontal displacement, the vertical displacement, the angular displacement and the length of the patching section is:

[0036]

[0037] According to the horizontal displacement, the vertical displacement, the angular displacement, the length of the patching section, and the length of the pre-embedded steel pipe on the arch seat, the calculation formula for calculating the displacement value of the second end of the pre-embedded steel pipe on the arch seat is:

[0038]

[0039] Among them, u c 、v c ,θ c u represents the horizontal displacement, vertical displacement and angular displacement of the upper chord tube port of the arch foot section; B 、v B Respectively represent the horizontal displacement and vertical displacement of the first end of the embedded steel pipe on the arch seat; u A 、v A They respectively represent the horizontal displacement and vertical displacement of the second end of the embedded steel pipe on the arch seat; d represents the length of the patching section, and L represents the length of the embedded steel pipe on the arch seat.

[0040] It should be noted that the method for calculating the displacement values ​​of the two ends of the embedded steel pipe under the arch seat based on the second displacement is the same as the method for calculating the displacement values ​​of the two ends of the embedded steel pipe on the arch seat based on the first displacement, and will not be repeated here.

[0041] Step S103 , calculating the actual coordinates of the steel pipe embedded on the arch seat and the actual coordinates of the steel pipe embedded under the arch seat according to the displacement values ​​of both ends of the steel pipe embedded on the arch seat and the displacement values ​​of both ends of the steel pipe embedded under the arch seat.

[0042] In this embodiment, the actual coordinates of the pre-embedded steel pipe on the arch seat are calculated based on the displacement values ​​of the two ends of the pre-embedded steel pipe on the arch seat. The calculation formula is:

[0043]

[0044] in, They represent the design coordinates of the first end and the second end of the embedded steel pipe on the arch seat respectively. They respectively represent the actual coordinates of the first end and the second end of the embedded steel pipe on the arch seat.

[0045] It should be noted that the design coordinates in this embodiment can be geodetic coordinates or relative coordinates established at an arbitrary point. The arbitrary point can be a point on the arch rib segment or a point on the pre-embedded steel pipe of the arch seat; correspondingly, the actual coordinates are coordinates in the same coordinate system as the design coordinates, which are coordinates calculated after considering the stress and deformation of the arch rib segment.

[0046] Correspondingly, the method for calculating the actual coordinates of the pre-embedded steel pipe under the arch seat according to the displacement values ​​of both ends of the pre-embedded steel pipe under the arch seat is the same as the above method, which will not be repeated here.

[0047] Step S104 , performing construction control on the pre-embedded steel pipes on the arch seat, the pre-embedded steel pipes under the arch seat, and the patching section according to the actual coordinates of the pre-embedded steel pipes on the arch seat and the actual coordinates of the pre-embedded steel pipes under the arch seat.

[0048] In this embodiment, construction control of the pre-embedded steel pipes on the arch seat, the pre-embedded steel pipes under the arch seat and the patching section is performed according to the actual coordinates of the pre-embedded steel pipes on the arch seat and the actual coordinates of the pre-embedded steel pipes under the arch seat, including: welding the pre-embedded steel pipes on the arch seat and the pre-embedded steel pipes under the arch seat to the rigid frame, and adjusting the installation position of the rigid frame according to the actual coordinates of the pre-embedded steel pipes on the arch seat and the actual coordinates of the pre-embedded steel pipes under the arch seat; pouring concrete on the rigid frame so that part of the pre-embedded steel pipes on the arch seat and the pre-embedded steel pipes under the arch seat are poured in the concrete; after installing the arch foot section and at least one arch rib segment predetermined before the pre-embedded steel pipes in the arch seat are hinged, the pre-designed patching section is installed.

[0049] It should be noted that if Figure 2As shown, the pre-embedded steel pipes in the arch seat are precisely positioned according to the obtained geodetic coordinates or relative coordinates and welded to the rigid frame 8 in the arch seat. Part of the steel pipes are cast in the arch seat concrete 9. After the deformation of the pre-embedded steel pipes in the arch seat is taken into account, the position of the rigid frame in the original design is changed. The installation position of the rigid frame needs to be adjusted accordingly based on the obtained geodetic coordinates or relative coordinates of the pre-embedded steel pipes in the arch seat. Figure 2 (a) is the design drawing, and 2(b) is the actual installation drawing after considering the deformation of the arch foot section. From the comparison of the two figures, it can be seen that the actual installation positions of the embedded steel pipe 5 on the arch seat and the embedded steel pipe 4 under the arch seat in 2(b) have been appropriately adjusted.

[0050] Furthermore, the arch foot section and other segments of the steel pipe arch are installed in accordance with a predetermined installation sequence until the segment before the arch rib hinge is closed, and the patching section is installed and welded to complete the hinge construction. Since the pre-buried steel pipes of the arch seat are pre-buried according to the coordinates obtained by calculating the deformation of the upper and lower chord tubes of the arch foot section, the coordinates take into account the influence of the deformation of the upper and lower chord tubes of the arch foot section on the pre-buried steel pipes of the arch seat, so precise alignment can be achieved, which can ensure that the misalignment of the patching section is within the allowable range of the specification.
