Description

Technical Field

[0001] The present application relates to the technical field of bridge engineering, and in particular to a construction method and system for a progressive and regressive assembled steel box tie arch bridge. Background Art

[0002] Currently, steel-box tied-arch bridges are widely used in bridge engineering. They possess the general characteristics of arch bridges, while also possessing their own unique features. They combine the advantages of both arch and beam structures, effectively sharing loads and fully utilizing the structural properties and combined effects of the beam's bending and the arch's compression. Key construction methods include in-situ support assembly, vertical arch rib lifting, and beam-arch top-pushing.

[0003] In related technologies, for the construction of steel box tie-arch bridges where the bridge deck is high above the river surface and the bridge deck width is narrow and the working space is limited, it is generally necessary to build a trestle on the water surface, and park or run ordinary cranes or gantry cranes on the trestle to assemble steel main beams and steel box arch ribs.

[0004] However, in related technologies, when using traveling cranes or gantry cranes on trestle bridges for hoisting operations, the lifting height cannot meet the assembly requirements of both the steel main beams and the arch ribs. Furthermore, the use of large-scale lifting equipment for assembly places high demands on on-site access roads and construction trestle bridges, significantly increasing construction costs and safety risks. Therefore, how to reduce the lifting height, avoid working in confined spaces, and reduce the investment in large temporary structures such as trestle bridges are urgent technical issues that need to be addressed by those skilled in the art. Summary of the Invention

[0005] The embodiments of the present application provide a construction method and system for a progressive and regressive assembly of a steel box tie arch bridge to solve the problems in the related art of high hoisting height, limited working space, and large investment in large temporary structures such as trestles during the construction of steel box tie arch bridges.

The steel main beam supports and steel main beam components in several subsequent segmental steel main beams are lifted to the bridge deck through the lifting station and transported to the lifting range of the full-rotating crane by a longitudinal trolley running on the longitudinal track.

[0016] In some embodiments, the method of sequentially hoisting a plurality of segmented steel box arch ribs in a direction opposite to the construction advancement direction of the steel main beam using a full-rotation crane traveling on the completed steel main beam includes:

[0018] Carry out the construction of subsequent segmental steel box arch ribs after the steel box arch rib closure section;

[0019] Assemble the steel box arch rib closure section.

[0020] In some embodiments, when the construction of several segmented steel box arch ribs is carried out in sequence to the steel box arch rib closing section, the steel box arch rib bracket and the steel box arch rib component are lifted to the bridge deck by the lifting station and transported to the lifting range of the full-rotation crane by the longitudinal movement trolley.

[0021] In some embodiments, the steel box arch rib closing section is arranged at the arch waist of the steel box arch rib close to the steel platform and close to the arch foot section.

[0036] The embodiment of the present application provides a construction method for a progressive and retrograde assembly of a steel box tie-arch bridge, which first builds a steel platform on the embankment, uses the steel platform as a platform for a full-rotation crane to carry out the hoisting construction of the steel main beam support and the steel main beam of the first section, uses the steel main beam support as a temporary support to support the steel main beam, and then uses the completed steel main beam as a platform for a full-rotation crane to carry out the hoisting construction of the steel main beam support and the steel main beam of the subsequent sections. At the same time, the hoisting construction of the subsequent steel box arch ribs is also carried out by moving the full-rotation crane on the steel main beam.

DETAILED DESCRIPTION

[0055] 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.

[0056] The embodiments of the present application provide a construction method and system for a progressive and regressive assembly of a steel box tie-arch bridge, which can solve the problems of the current steel box tie-arch bridge hoisting operation, such as the bridge deck being high above the river surface or the ground, the bridge deck being narrow, the limited working space, and the problem of increased construction costs caused by the investment of a water trestle.

[0057] Reference Figure 1-16 As shown, a construction method of a progressive and regressive assembled steel box tied arch bridge provided by the present application includes the following steps:

[0058] S1: Complete the construction of the foundation and substructure 1 at both ends of the steel box tied arch bridge.

[0059] Reference Figure 1 Specifically, the foundation and lower structure 1 include piers and foundations at both ends of the arch bridge.

[0060] S2: A steel platform 2 is set up on the embankment at one end of the steel box tied arch bridge, and a full-rotation crane 3 is set up on the steel platform 2.

[0061] Reference Figure 2 Specifically, when the steel platform 2 is built, it is erected along the bridge axis on one side of the steel box tied arch bridge. The steel platform 2 serves as the bearing foundation of the full-revolving crane 3. When erecting the full-revolving crane 3, an ordinary crane is used to lift and assemble the components of the full-revolving crane 3 on the shore land. The full-revolving crane 3 has a self-propelled function.

[0062] S3: Use a fully revolving crane 3 to sequentially hoist several segments of steel main beams 4 along the longitudinal direction of the bridge. For each segment of steel main beam 4, a fully revolving crane 3 is first used to set up the steel main beam supports 5. Steel main beam components 401 are then assembled on the steel main beam supports 5. The fully revolving crane 3 then hoists the first segment of steel main beam 4 onto the steel platform 2. Subsequent segments of steel main beams 4 are then hoisted using the fully revolving crane 3 from the completed steel main beams 4. Adjacent steel main beam components 401 are connected and secured by welding or bolting.

[0063] Specifically, refer to Figure 3-9 As shown, including:

[0064] S301: Construction of the first segment steel main beam 4 is performed on the steel platform 2.

[0065] Reference Figure 3 and Figure 4 During the construction of the first section steel main beam 4, materials such as the steel main beam component 401 and the steel main beam support 5 are transported by land to the lifting range of the full-revolving crane 3, and then lifted from the ground to the bridge deck height by the full-revolving crane 3.

[0066] S302: The full-revolving crane 3 automatically moves forward a distance of a segment steel main beam 4, and then performs hoisting construction of the next segment steel main beam 4, and repeats this step until the construction of the subsequent segment steel main beam 4 is completed.

[0067] When the full-revolving crane 3 moves, a track for the full-revolving crane 3 to move needs to be set up on the built steel main beam 4, and the full-revolving crane 3 moves on the track by itself.

[0068] Furthermore, during construction of the steel main beam 4 located on the embankment, the steel main beam bracket 5 and the steel main beam component 401 are transported by land to the lifting range of the full-revolving crane 3, and then lifted from the ground to the bridge deck level using the full-revolving crane 3. In this step, the lifting range of the full-revolving crane 3 must meet the requirements for lifting components on the land near the bank, and the full-revolving bridge deck crane must be equipped with sufficient wire rope length.

[0069] Reference Figure 7 After the construction of the steel main beam 4 on the embankment is completed, the lifting station 6 is assembled on the steel platform 2, and the longitudinal movement track along the longitudinal direction of the bridge is assembled on the completed steel main beam 4. The steel main beam bracket 5 and the steel main beam component 401 in the subsequent several segment steel main beams 4 are lifted to the bridge deck through the lifting station 6, and are transported to the lifting range of the full-rotation crane 3 by the longitudinal movement trolley 7 running on the longitudinal movement track.

[0070] Among them, the lifting station 6, the longitudinal movement track and the longitudinal movement trolley 7 are all assembled using the full-rotation crane 3.

[0071] Reference Figure 6 After the construction of the steel main beam 4 on the embankment is completed, the full-wheel crane can also directly lift the steel main beam component 401 and the steel main beam support 5 from the ground to carry out the construction of the first section of the steel main beam 4 located on the river surface. After the construction of the steel main beam 4 in this section is completed, the lifting station 6, longitudinal movement track and longitudinal movement trolley 7 can be constructed.

[0072] S4: A full-rotating crane 3 traveling on the completed steel main beam 4 is used to sequentially hoist several segmented steel box arch ribs 8 in a direction opposite to the construction advancement direction of the steel main beam 4. During the construction of each segmented steel box arch rib 8, a steel box arch rib support 9 is first erected, and then the steel box arch rib component 801 is assembled on the steel box arch rib support 9.

[0073] Specifically, refer to Figure 10-16 Shown, including:

[0074] S401: construct several segments of steel box arch ribs 8 in sequence until the steel box arch rib closing section 802.

[0075] Reference Figure 10-12 Among them, the steel box arch rib bracket 9 and the steel box arch rib component 801 are lifted to the bridge deck by the lifting station 6, and transported to the lifting range of the full-rotation crane 3 by the longitudinal movement trolley 7.

[0076] Furthermore, after the full-revolving crane 3 completes the construction of a section of steel box arch rib 8, it moves back a distance of a section of steel main beam 4 before carrying out the hoisting construction of the next section of steel box arch rib 8.

[0077] S402: Carry out construction of the subsequent segment steel box arch rib 8 of the steel box arch rib closing section 802.

[0078] Reference Figure 13 and Figure 14 , wherein the steel box arch rib closing section 802 is arranged at the arch waist of the steel box arch rib 8 on the side close to the steel platform 2 and close to the arch foot section. When constructing the subsequent segment steel box arch rib 8 of the closing section, the lifting station 6 and the longitudinal movement track and the longitudinal movement trolley 7 are first dismantled, and the full-revolving crane 3 retreats to the steel platform 2 to carry out the subsequent steel box arch rib 8 arch foot section construction of the steel box arch rib closing section 802. Accordingly, the steel box arch rib bracket 9 and the steel box arch rib component 801 are transported by land to the lifting range of the full-revolving bridge crane.

[0079] S403: Assemble the steel box arch rib closing section 802.

[0080] Reference Figure 15 In order to ensure the consistency of the internal forces of the arch ribs on both sides, a predetermined force is applied to the steel box arches at both ends of the closing mouth according to the internal force value measured at the corresponding position of the closing section on the other side, and the closing section is installed and welded at the designed closing temperature.

[0081] S5: dismantle the full-slewing crane 3, the steel platform 2 and the steel box arch rib support 9, and dismantle the steel main beam support 5 after completing the installation of the steel box tied arch bridge hanger 10 and the bridge deck system construction.

[0082] Reference Figure 16 Specifically, a ground crane is used to dismantle the full-rotating crane 3 and the steel platform 2, and then the subsequent processes of the steel box tied arch bridge are completed. The subsequent processes include, in order, the dismantling of the steel box arch rib support 9, the installation of the hanger 10, the construction of the bridge deck system, and the dismantling of the steel main beam support 5.

[0083] Through the above-mentioned arrangement, a steel platform 2 is first built on the embankment, and the steel platform 2 is used as a platform for the full-rotation crane 3 to carry out the hoisting construction of the steel main beam support 5 and the steel main beam 4 of the first section, and the steel main beam support 5 is used as a temporary support to support the steel main beam 4, and then the completed steel main beam 4 is used as a platform for the full-rotation crane 3 to carry out the hoisting construction of the steel main beam support 5 and the steel main beam 4 of the subsequent sections. At the same time, the subsequent hoisting construction of the steel box arch rib 8 is also carried out by moving the full-rotation crane 3 on the steel main beam 4. Therefore, the water surface or ground hoisting operation is converted to the bridge deck hoisting operation, the lifting height is greatly reduced, and the progressive and retrograde assembly avoids the problems of narrow bridge deck space and large interference in hoisting operations. Compared with the traditional in-situ bracket assembly method, it is safer and more efficient, and the investment cost is greatly reduced.

[0084] The embodiment of the present application also provides a construction system for progressive and regressive assembly of a steel box tie arch bridge, which includes a steel platform 2, a full-rotation crane 3, a steel main beam support 5 and a steel box arch rib support 9.

[0085] Reference Figure 1-6 As shown, the steel platform 2 is arranged on the embankment at one end of the steel box tied arch bridge, and the full-revolving crane 3 is used to lift the steel main beam 4 and the steel box arch rib 8, and the full-revolving crane 3 lifts the steel main beam 4 and the steel box arch rib 8 to be constructed on the steel platform 2 and the completed steel main beam 4, and the full-revolving crane 3 has a self-propelled function; the steel main beam support 5 is supported on the embankment or the riverbed and the bottom is located underground for temporarily supporting the steel main beam 4; the steel box arch rib support 9 is erected on the steel main beam 4 for temporarily supporting the steel box arch rib 8.

[0086] Reference Figure 7 As shown, a lifting station 6 is also built on the steel platform 2. Specifically, the lifting station 6 is built after the full-rotating crane 3 is moved out of the steel platform 2. The lifting station 6 is used to lift the steel main beam component 401, the steel main beam support 5, the steel box arch rib support 9 and the steel box arch rib component 801 to the bridge deck height.

[0087] Reference Figure 7-12 As shown, further, longitudinal tracks are laid on the steel platform 2 and the completed steel main beam 4, and the longitudinal tracks are arranged along the longitudinal direction of the bridge. A longitudinal trolley 7 is installed on the longitudinal tracks, and the longitudinal trolley 7 moves on the longitudinal tracks to transport the steel main beam component 401, the steel main beam support 5, the steel box arch rib support 9 and the steel box arch rib component 801 to the lifting range of the full-rotation crane 3.
