Detailed Description
The bridge construction method provided by the invention is further described in detail below with reference to the accompanying drawings and specific embodiments. Advantages and features of the present invention will become apparent from the following description and from the claims. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is merely for the purpose of facilitating and distinctly claiming the embodiments of the present invention.
In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "left", "right", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
As shown in fig. 1, an embodiment of the present invention provides a bridge construction method, including the following steps:
s1, constructing the steel pipe pile of the bridge lower structure;
s2, constructing a foundation bearing platform of the bridge lower structure, and erecting at least two temporary supports;
s3, after the temporary support is completely erected, carrying out midspan sectional hoisting on the bridge, wherein the midspan sections are bridge sections except bridge sections at two ends of the outermost side of the bridge;
s4, maintaining the foundation bearing platform of the lower structure of the bridge, and butt-welding the hoisted midspan sections;
and S5, hoisting and welding the rest bridge sections.
The substructure includes a bridge steel pipe pile and a foundation cap.
The bridge in the embodiment is a semi-self-anchored stayed cable bridge, and the specific structure of the bridge is shown in fig. 2. It can be seen that the bridge construction phase is divided into 5 bridge segments, namely, a first bridge segment 1, a second bridge segment 2, a third bridge segment 3, a fourth bridge segment 4 and a fifth bridge segment 5, wherein the second bridge segment 2, the third bridge segment 3 and the fourth bridge segment 4 are midspan segments, and the first bridge segment 1 and the fifth bridge segment 5 respectively include a pylon. The bridge also includes 4 temporary supports for supporting each bridge segment. Therefore, when the number of the temporary supports is N, the number of the bridge segments is N +1, wherein N is larger than or equal to 3, and constructors can set the number of the bridge segments according to actual requirements.
As can be seen in fig. 2, the temporary supports include an onshore temporary support 7 and an aquatic temporary support 8.
As shown in fig. 3 and 4, the onshore temporary support 7 comprises steel box girders 12 for pressure transfer members, steel columns 13 for vertical support, short columns 16 for supporting bridge segments, and angle irons 14 for diagonal support.
In order to improve the stability of the temporary shore support 7, a roadbed box 15 for temporary support is arranged between the temporary shore support and the bottom surface for pressure diffusion.
As shown in fig. 5 and 6, the marine temporary support 8 includes a steel truss strut 20 for vertical support, an operation platform 18 for construction of a constructor, a staircase 19 for up and down movement of the constructor, and a stub 16 for supporting a bridge segment.
In actual construction, the difficulty of machining the foundation cap 11 of the substructure is great, and the machining period is long, so in construction, after the steel pipe pile 10 is completely constructed in the step S1, the construction of the foundation cap 11 is started until the step S4 is completed, and the construction of the foundation cap 11 can be performed in this period of time, so as to shorten the construction time.
Meanwhile, in order to reduce the influence on the construction of the foundation cap 11, in the step S3, the midspan section includes 3 bridge sections, and the hoisting sequence is performed from the middle of the bridge to two sides of the bridge.
In the construction process, a flood prevention wall 9 is arranged between the shore temporary support 7 and the river to enhance the safety of the shore temporary support 7.
Of course, in the step S3, the floating crane is used to hoist the midspan section of the bridge, and the hoisting sequence is performed from the middle to both sides.
In addition, as the bridge cable tower is positioned on the bridge segments at the two ends of the outermost side of the bridge, after the bridge segments at the two ends of the outermost side of the bridge are hoisted, the stay cables 6 can be installed.
It should be noted that the bridge construction method of the present invention can also be used for ground anchored cable-stayed bridges and self-anchored cable-stayed bridges.
In conclusion, in the bridge construction method, the construction of the substructure and the bridge segment is carried out simultaneously in the construction process, so that the construction time of the bridge is greatly shortened, the construction progress is improved, and the river closure time is reduced.
Finally, it should be noted that the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
